Utilities Manual Regulations
The Delaware Department of Transportation through its Transportation Solutions - Utilities Section has developed revised regulations for the installation, adjustment, and maintenance of utility lines and appurtenances within the rights-of-way of Delaware's highways. These regulations define the requirements which apply to utility accommodation along or within the rights-of-way of State-controlled highways, and State-maintained streets and roads within suburban developments or within the incorporated limits of a municipality.
The Utilities Manual revises and updates the DelDOT Utilities Design Manual, effective in October 1995.
Public Comment Period and Notice of Public Hearing
The Departments will take written comments on the Regulations from January 1, 2007 through January 31, 2007. Any requests for copies of the Utilities Manual, or any questions or comments regarding this document should be directed to:

The Mission of the State of Delaware's Department of Transportation is to provide a safe, efficient, and environmentally sensitive transportation network that offers a variety of convenient, and cost-effective choices for the movement of people and goods.
Effective management and design of utility installations are imperative for the safe and expedient construction and maintenance of the transportation network. Close coordination with utility owners is essential to meet these objectives.
This manual outlines the general practices, policies, and procedures that affect the relationship between the Delaware Department of Transportation, hereafter referred to as the Department or DelDOT, and those entities desiring to place utility lines and appurtenances within the rights-of-way of this State. This manual explains the requirements and procedures necessary to facilitate utility installation, relocation, maintenance as well as any utility work in conjunction with highway project construction within Department right-of-way.
1.1 Purpose And Objectives
1.1.1 The overriding goal for this manual is to allow the user to locate and understand those regulations and procedures that are most pertinent to their activities in the highway-utilities process. The process embraces a large and exceedingly complex series of issues. This manual simplifies and condenses these issues for ease of location by the user.
1.1.2 The manual has been prepared to accomplish these objectives:
1.1.3 The information in this manual applies to all public and some private facilities, including (but not limited to) electric power, telephone, telegraph, communications, cable TV, lighting, water, gas, oil, petroleum, steam, chemicals, sewage, drainage, irrigation, and similar lines that are located within the rights-of-way of highways under the Department's jurisdiction. Underground, surface, and overhead facilities-whether singular or in combination-are covered by this manual.
1.2 Statutory Authority
1.2.1 The Delaware Code provides the Department with the authority and responsibility to regulate the use of all utilities on state highway rights-of-way. For the benefit of the reader, this manual reviews applicable portions of Delaware law.
1.2.2 The Department has the sole legal authority to control the use of state highway rights-of-way. Vesting this control in a single agency was necessary to ensure the safety of motorists and the proper operation of highway facilities. The Department has formulated the guidelines, policies, and procedures in this manual as tools for regulating utilities to achieve the aforementioned purposes.
1.2.3 The "Delaware State Highway Department" was established into law on April 2, 1917. Chapter 166 of the 1935 Code amended the original Act that created the Highway Department. Additional amendments, including Title 17 of Delaware Code, were enacted by the Legislature on February 11, 1953, and approved by the governor on February 12, 1953, including all prior amendments. This act provides authorization for the State to participate in the acquisition of rights-of-way, the placement of new utilities, and the adjustment of existing utilities.
1.2.4 Title 26 of the Delaware Code (1953) provides authorization for the State to control new installations of pipes, conduits, and wires above or beneath the public roads.
1.2.5 Section 143, Title 17, Delaware Code, established by law on January 16, 1962, made the State responsible for the entire cost of altering or relocating utilities that are within public highway rights-of-way-when the utility facilities are owned or operated by a municipality, governmental body, or subdivision of the State-as necessitated by highway construction, reconstruction, relocation, repair, or maintenance.
1.2.6 Section 132, Title 17, Delaware Code (1966) provides for the State to reimburse the owner for the expense of relocating public utility facilities necessitated by any project where the State is to be reimbursed at least 90% of the project cost from federal funds or by the federal government or any agency thereof. Such expense is to be the amount paid by the owner that is properly attributable to the relocation, after deducting therefrom any increase in the value of the new facilities and any salvage value derived from the old facilities.
1.2.7 Section 143, Title 17, Delaware Code, amended on June 29, 2004, allows the Department of Transportation flexibility to negotiate alteration or relocation agreements with public utilities in order to improve efficiency and fairness. While not required to do so, the Department may choose to enter into an agreement with a public utility for this purpose.
1.2.8 The opinion of the Court of Chancery, State of Delaware (1963) is the basis on which the State reimburses utility owners the expense of relocating public utility facilities on rights-of-way for which they hold title, or have permission or easement for occupancy, as necessitated by any project.
1.2.9 Adherence to the policies, practices and procedures of the Department of Transportation-and, more specifically, to the requirements described in the Utilities Manual-must be undertaken with full knowledge of, and compliance with, Chapter 8, Title 26, of the Delaware Code entitled "Underground Utility Damage Prevention and Safety." The Department's commitment to provide for the protection of public health and safety is of major importance and must be maintained at all times.
1.3 Construction And Location Requirements
The State reserves the right to review and approve the detailed location and design of all utility installations, adjustments, or relocations affecting the highway rights-of-way, and will issue permits for proposed utility work. Chapter 3 describes permitting requirements.
1.4 Exceptions To Requirements
The utility company shall submit any request, for deviation from the standards described in this manual, due to extreme hardship, to the Department. The request shall be in writing and must include full justification surrounding the hardship. The Department will assess the situation and provide recommendations. The documentation will be sent to the Utilities Engineer for coordination and comment, who shall then forward it to the Chief Engineer for final action.
1.5 Transmittal Of Information
Where the manual specifies the submittal of plans or other documents, utilities are encouraged to submit electronic files with the Department's approval.
If utilities choose to submit plans or other documents electronically, their systems and GIS databases must be compatible with DelDOT's current systems in order to transfer files electronically.
The requirements presented in this chapter apply to the location and design of all utility installations within the highway rights-of-way.
2.1 Types Of Work
There are two distinct types of utility work in highway rights-of-way:
2.1.1 Permit and New Service Installation Work. This work usually encompasses the maintenance of existing utility facilities or the installation of new services or utility distribution facilities. The appropriate District Public Works staff issues the permits and inspects the work.
The purpose of the permit is to alert DelDOT that the work is taking place, so that DelDOT can review the traffic control, proposed locations and design and inspect the work to ensure the integrity of the roadway.
2.1.2 Project Design and Facility Relocation Work. This work results from highway construction projects where it is necessary to relocate utility facilities. Project design work is coordinated through the Utilities Engineer and the Utilities Section. A permit is usually not required for this type of work because the highway construction project supervisor inspects the work. However, a permit is required for utility work in advance of construction where DelDOT Construction is not yet assigned to the project. The permit is processed via the District Public Works office. A permit is also required for preliminary test holes for the location of utilities unless the District waives the requirement.
Traffic control for project design work is coordinated with the highway contractor, the highway construction project supervisor and the Construction District to ensure proper safety standards are employed.
The District Public Works Section administers permit work in its district. The Construction Group Engineer administers highway construction projects. The Chief Engineer and the Assistant Director of Project Development are responsible for the project design. Any situations that cannot be resolved through the normal process may be forwarded to the appropriate authority.
2.2 Highway Safety And Traffic Control
The Department considers highway safety a high priority that is an essential and indispensable component of every project from planning through the design and construction phases. Therefore, companies that install, maintain, service, operate, or otherwise work upon utilities within highway rights-of-way are always obligated to consider the safety of the general public. This includes providing appropriate traffic control within work areas.
2.2.1 Traffic Control
All reasonable measures shall be taken for the protection and safe operation of traffic during and after installation of facilities. For all utility maintenance or construction operations within public highway rights-of-way:
22.214.171.124 All traffic control shall conform to the requirements specified in the most current DelDOT manual Traffic Controls for Streets and Highways Construction, Maintenance, and Utility Operations ("Traffic Control Manual") and any other applicable State and federal regulations.
126.96.36.199. A traffic control plan, referencing the Traffic Control Manual, must be submitted and approved whenever a permit is required.
188.8.131.52 Failure by a utility to provide for traffic safety will be cause for immediate suspension of operations. The work will not be allowed to continue until the District is satisfied that proper traffic control is established.
184.108.40.206 If there are any discrepancies between the Manual on Uniform Traffic Control Devices (MUTCD) and the Traffic Control Manual, the DelDOT Safety Section shall be contacted for clarification. In all questions of interpretations of the MUTCD and the Traffic Control Manual, the judgment of the Chief Traffic Engineer shall be final. The protection prescribed for each situation shall be based on the speed and volume of traffic, duration of operation and exposure to hazards. The term "street" refers to all the streets in any municipality, including cities, towns, villages, or other local jurisdictions.
2.2.2 Traffic Control And Safety References
220.127.116.11 Title 17 of the Delaware Code provides for the establishment of traffic control and safety standards to be observed during utility construction and maintenance operations on or adjoining any public highway, road, or street. Public and private utilities, contractors under contract with utility companies, and all others engaged in utility construction and maintenance are required to comply with these standards.
18.104.22.168 The Traffic Control Manual explains in detail the principles and requirements of traffic control and safety standards. It covers traffic control procedures, responsibilities of involved parties, required training for personnel, and descriptions of approved control devices.
22.214.171.124 Responsible utility officials are strongly encouraged to obtain the Traffic Control Manual, study its contents, and make copies available to their field supervisors. The Traffic Control Manual can be found online at http://www.deldot.gov/static/publications_forms.shtml. The standards are to be implemented through the training and supervision of utility employees. Failure to meet standards will result in stoppage of work until deficiencies are brought into compliance.
126.96.36.199 All workers within state right of way shall have high visibility safety apparel that meets ANSI 107-2004 standard requirements. This apparel will meet the standard performance for Class 2 risk exposure. The apparel background material color shall be fluorescent yellow-green as defined in the standard. The reflective material shall be either orange, yellow, white, silver, yellow-green, or a fluorescent version of these colors, and shall be visible at a minimum distance of 1000'. For nighttime work, apparel meeting standard performance for Class 3 risk exposure is recommended.
2.2.3 Traffic Control Plan
188.8.131.52 The traffic control plan is an important aspect of the project. It shall be prepared by qualified individuals and understood by all affected parties before work begins. In preparing the traffic control plan; the sample cases in the Traffic Control Manual shall be followed. The plan must be submitted or traffic control case identified when applying to the District Office for a construction permit. If utility officials need to veer from standard case studies, an ATSSA Certified Traffic Control Supervisor must submit changes to DelDOT Safety for approval prior to applying for permit.
184.108.40.206 The utility work shall not begin until the District approvals have been obtained and the approved permit information including traffic control are on the job site. Once the job has begun, the utility inspectors must ensure that the plan is followed throughout the project.
In the case of emergency work where there is no prior approval of a traffic control plan; the utility is still required to follow the DelDOT Traffic Control Manual.
The requirement for a utility traffic control plan may be waived on construction projects when the utility adjustments are made simultaneously with the highway contractor's operations and the highway contractor provides the traffic control. Under these circumstances, the utility and highway contractor must cooperate and coordinate their work so that neither is delayed by the other's operation. See Section 220.127.116.11.
2.2.4 Flaggers And Traffic Control
18.104.22.168 Flaggers are essential in controlling traffic when one lane is closed and motorists must alternately use the remaining lane. Other important assignments for flaggers are necessary in utility work, such as lane closures for equipment passage, the pulling of cable crossings, and the control of traffic speed.
22.214.171.124 The Department has specific requirements for flagger warning signs, safety clothing, training, and associated flagger concerns, as described in the Traffic Control Manual. Utility supervisors are expected to understand and abide by these requirements. Flaggers are required to be ATSSA certified, expected to be alert, and to know the correct way to stop traffic, slow it down, and keep it moving.
2.2.5 Inspection Of Traffic Control
Routine inspections of traffic control elements must be made to ensure acceptable levels of operation. Inspections will be performed by trained District personnel and shall be accomplished at a frequency corresponding to the magnitude of the:
126.96.36.199 utility activity,
188.8.131.52 traffic volumes, and
184.108.40.206 other contributing factors.
When a utility or utility contractor fails to follow the approved traffic control plan, inspectors will suspend the work until the required traffic control is in place. Failure to follow the traffic control plan violates 21 Del.C. §4105 and is subject to punishment by law.
2.3 Location Of Utility Facilities
In planning utility locations on highway rights-of-way, consideration must be given at all times to sound engineering principles, public safety, and economic benefits to the State. The planning must consider safety, the visual quality of the highway, and efficiency of maintenance.
2.3.1 Specifically, the following items must be considered:
220.127.116.11 Minimize future project interference. New utility facilities shall be located to minimize the need for later adjustments to accommodate future highway improvements or other utility installations. The location should allow for adequate access to the facilities and accommodate future maintenance. In addition to meeting with DelDOT to discuss future projects, the following are sources to check on projects:
18.104.22.168 Minimize future interference to traffic. Consider methods to maintain utility facilities with minimum interference to highway traffic.
22.214.171.124 Preserve safe traffic operation and future space. New longitudinal installations shall be located on a uniform alignment as near as practicable to the right of way line and outside the clear zone to provide a safe environment for traffic operation and preserve space for future highway improvements or other utility installations.
126.96.36.199 Comply with ADA. The location of utility facilities and appurtenances shall be in accordance with the Americans With Disabilities Act.
188.8.131.52 Allow only Perpendicular Crossings. Utility lines shall cross the highway on a line generally perpendicular to the highway alignment;
184.108.40.206 Consider utility facility's ownership, operation, and maintenance methods for all facilities that it installs within the boundaries of the right-of-way as well as private underground services or other facilities.
220.127.116.11 Comply with Clearances and Clear Zone policies. Conform to horizontal and vertical clearances of aboveground utility lines with the "clear zone" roadside policies applicable to the system and the particular highway section involved. The locations of aboveground utility facilities shall be consistent with the clearances applicable to all roadside obstacles for the type of highway involved. See Appendix A for the definitions of "clear roadside policy", "clear zone" and "horizontal clearances."
Clear zones are established for new construction and major reconstruction projects. Clear zones on other existing roadways may be less than desirable. Utilities shall check with the District Public Works Engineer to determine the clear zone widths for specific locations for utility work performed under permits. The calculation of clear zone widths is explained in DelDOT's Road Design Manual and the AASHTO Roadside Design Guide.
If there is no feasible alternative to locating appurtenances within the clear zone, the appurtenances (including fire hydrants) must meet breakaway criteria.
18.104.22.168 Consider future drainage. Future drainage requirements shall be considered when determining location of utility installations. Existing swales or ditches may need to be deepened. New drainage ditches may need to be constructed. New storm water drainage pipelines may need to be installed in the future.
2.3.2 Highways With Fully Controlled Access
Freeways and some expressways have full control of access. Full control of access to highways means that preference is given to through traffic by providing access connections only with selected public roads and by prohibiting at-grade crossings and direct private driveway connections. Delaware highways with full access control include:
22.214.171.124 Crossing Of Freeway Right-of-way
New utility installations, and adjustments or relocations of existing utilities, are permitted to cross a freeway only in exceptional cases. The installation's effect on safety must be considered. All installations shall cross the freeway on a line perpendicular to its longitudinal alignment. Underground crossings are preferred. Overhead crossings are not desirable and shall be avoided. If a utility believes there is no feasible alternative to an overhead crossing, it must submit a written request to the district. The utility request must include the proposed cost of the overhead installation, describe other alternatives, and detail the associated costs of those alternatives. District Public Works will use the information in making a final decision.
Aerial, Aerial service connections, Underground
Written hardship request with detailed estimates and justification will be considered
The following applies to developed areas or areas that are planned for development:
126.96.36.199 Utilities Along Freeways - Lateral Positioning
188.8.131.52.1 Longitudinal installations of utilities will not be permitted within the denial-of-access lines of a freeway and other roads as determined by District Public Works. Frontage roads, where provided, may be used for placement of utilities with the approval of the District Public Works Engineer. Utilities located outside the access lines cannot be serviced by entrance from through-traffic roadways or ramps.
Lateral Positioning on Freeways
Lateral Positioning on Freeways
Within denial of access lines, Frontage Roads, Other Roads
Written hardship request with detailed estimates and justification will be considered
Outside denial of access lines
184.108.40.206.2 Utilities located on existing highway rights-of-way where the highway facility is being upgraded to a freeway must normally be moved. Permission for such utilities to remain in place may be granted if all service can be made from outside the access control line.
220.127.116.11 Utilities Along Roads Or Streets Crossing Freeways
Where a utility follows a road or street that crosses a freeway, the utility shall cross the freeway on the location of the crossroad or street, and generally within its right-of-way. The utility must be serviced without access from the freeway. All work is subject to State and FHWA regulations in effect at the time. Overhead crossings are not desirable and shall be avoided as noted in Section 18.104.22.168.
2.3.3 Partial-access-control Highways
On partial-access-control highways, preference is given to through traffic to a degree that, in addition to access connections with selected public roads, there may also be some other roads crossing at grade as well as some private driveway connections. Except for the types of highways listed under full access control in Section 2.3.1, most highways in Delaware have partial access control.
22.214.171.124 Utilities Along Partial-access-control Highways - Lateral Positioning
126.96.36.199.1 In considering an aboveground facility along a partial-access-control highway, the following constraints apply with respect to the location of the facilities. Any exceptions to these requirements can be submitted by the utility and will be considered by the Department.
188.8.131.52 Utilities Along Highways - Vertical Positioning
184.108.40.206.1 Overhead electric power and communications structures, lines and cables shall be installed in compliance with the latest edition of the National Electrical Safety Code. Existing lines and cables shall be maintained at minimum clearance of 23.5 feet above track rails of railroads and a minimum clearance of 18 feet above roads, streets, entrances and other areas subject to truck traffic. The above two clearances shall be maintained under all conditions, i.e. maximum conductor sag conditions (subject to terms of railroad permit requirements) and a minimum of 18 feet above all roadways-or in accordance with the codes described in Section 2.4, whichever is greater.
220.127.116.11.2 The owner of utility facilities is responsible for moving them to eliminate any visual obstruction or interference to any traffic control device. This includes moving structures, overhead lines and cables, splice boxes, enclosures, and other appurtenances in order to provide adequate visibility of a traffic control device.
18.104.22.168 Historic Sites, Scenic Areas, Parks, Etc.
Aboveground utility installations-including those needed for highway purposes such as highway lighting or to serve a weigh station, rest area, or recreation area-are not permitted on highway rights-of-way or other lands which are acquired or improved with federal aid or direct federal highway funds and are located within or adjacent to areas of scenic enhancement and natural beauty. Such areas include public park and recreational lands, wildlife and waterfowl refuges, historic sites as described in 23 U.S.C. 138, scenic strips, overlooks, rest areas, and landscaped areas. However, the Department may permit exceptions provided that the conditions described in the current Program Guide for Utility Adjustments on Federal-Aid Highways are met. Relocation of pre-existing utility facilities from overhead to underground is subject to reimbursement within the guidelines described in Section 4.0.
22.214.171.124 Subdivision Streets Not Yet Accepted For State Maintenance
The Subdivision Developer shall be responsible for submitting utility installation site plans to District Public Works for review and approval prior to commencement of street construction within the subdivision and prior to utility installation.
It is not necessary for a utility to obtain a construction permit in new subdivisions. Upon completion and acceptance of the subdivision streets, the utilities that are located within the State right-of-way shall be franchised in accordance with the existing Annual Master Franchise for each utility.
The utilities in a subdivision will be located as follows:
126.96.36.199.1 Utilities will be allowed within the right-of-way.
188.8.131.52.1.2 Aboveground utilities must be avoided if possible. If pole lines are to be used, they must be placed behind the clear zone.
184.108.40.206.1.3 Where feasible, underground utilities shall be placed behind the proposed curb line or in an established utility easement.
220.127.116.11.1.4 The main lines of underground utilities must be longitudinally located between the right-of-way line and the curb or edge of pavement-except for sanitary sewers that will be placed to avoid the wheel path when they cannot be located outside the roadway. If possible, sanitary sewers should avoid the crown of the roadway. Service lines may cross under the paved area to connect residences with main lines.
18.104.22.168 Subdivision Streets Accepted For State Maintenance
Utility construction permits are required for existing subdivisions. Existing underground utilities will be permitted to remain in place in subdivisions with streets currently maintained by the Department. However, any utilities that are upgraded shall be located according to Section 22.214.171.124, provided there is enough right-of-way to place them behind curbs.
2.4.1 A Master Franchise must be in force for any utility facilities present in the highway right-of-way. The utility's proposed design in all cases must:
2.4.2 Permit And New Service Installation
126.96.36.199 The District Public Works Engineer will review a permit application for new or existing utilities, maintenance work and re-construction, and some utility work in advance of highway construction. If acceptable, the District Public Works Section will approve the:
188.8.131.52.1 proposed location for the utility facility, and
184.108.40.206.2 methods of installing and/or attaching the facility and repairing the highway or structure.
220.127.116.11 The District will review and approve the traffic control plan to ensure highway safety, including the safe and free flow of traffic.
2.4.2 Project Design And Facility Relocation
On DelDOT highway construction projects the Utilities Engineer will coordinate, review, and approve the utility's proposed plans for the:
18.104.22.168 Utility installations on, over, or under the rights-of-way of State highways, and utility attachments to highway structures, are to meet or exceed the requirements listed below as well as any other applicable codes or regulations.
22.214.171.124 Provisions for future expansion of utility facilities are to be made when planning for adjustments to existing facilities or preparing for new installations.
126.96.36.199 Underground utilities must consider safe trenching practices when preparing their designs and constructing their facilities. Both the utilities and their contractors must comply with all Occupational Safety and Health Administration (OSHA) requirements while working on highway rights-of-way. If unsafe work environments exist, work must stop until safe conditions are established or restored.
2.4.5 Other Permits
Utilities are responsible for obtaining all required permits from municipal, State, and federal governmental agencies and railroads. Examples of these permits include, but are not limited to:
2.5 Utility Clearances And Depth Of Cover
2.5.1 Positioning And Clearances
188.8.131.52 Vertical and horizontal clearances between utilities and utility clearances above roadways must conform to the utility codes cited in Section 2.4 and any other applicable industry codes and standards.
184.108.40.206 The following chart summarizes positioning and clearances that are mentioned in other sections of the Utilities Manual. Please see the appropriate section of the Utilities Manual for further details.

2.5.3 For Highway Appurtenances
220.127.116.11 Utilities must provide the minimum overhead clearances above the roadway defined in the references listed in Section 2.4. Appropriate clearances from signal poles shall also be maintained, as applicable codes require.
18.104.22.168 Utility accesses and valve covers shall not be located in the roadway of rural highways. If there is no feasible alternative in urban and suburban areas, they shall not be located in a wheel path or in the centerline of the roadway.
22.214.171.124 Horizontal clearances will be in accordance with the clear zone requirements described in the DelDOT Road Design Manual and A Policy on Geometric Design of Highways and Streets (AASHTO's Green Book). Exceptions must have the approval of the District Public Works Section.
2.6 Underground Installations
2.6.1 Underground Utilities Crossing Highways
Avoid utility crossings in deep cuts, near bridge and retaining wall footings, and at highway cross drains where flow of water, drift, or streambed load may be obstructed and in wet or rocky terrain. The crossings shall also be avoided where it is difficult to attain minimum cover, and through paved or unpaved berm slopes under structures. See Section 2.3 for more information regarding crossings of freeways and partial-access-control highways. refer to section 2.6.3 for more information regarding pipelines.
2.6.2 Installation Methods
126.96.36.199 Directional Boring, Jacking And Push-augering
188.8.131.52.1 Directional boring is the industry standard and the method accepted by the Department. Boring is defined as the operation by which large carriers or casings are jacked through oversize bores. The bores are carved progressively ahead of the leading edge of the advancing pipe as soil is mucked back through the pipe. Jacking is defined as the pushing of a sleeve or casing pipe under a highway to make an underground utility crossing without disturbing the roadbed by open trenching.
184.108.40.206.2 Utilities must provide plans for proposed jacking, push-augering, or directional bore operations for approval by the District Public Works Section when applying for a construction permit. Directional bores are the preferred method and shall be considered wherever possible. Pits for jacking, push-augering or directional bore are not permitted in a proposed paving area.
220.127.116.11.3 The pits for jacking, push-augering, or directional bore must be excavated no closer to the roadway than 5 feet from the edge of an improved shoulder. Where the shoulder is dirt or grass, the pit excavation may encroach on the shoulder but must remain at least 10 feet from the edge of pavement. Adequate measures must be taken to ensure traffic safety and the integrity of the roadway, especially where the pit is so close to the traveled way. Two approved pit layouts are shown in Figure 2-1. For curb-and-gutter sections, pits must be a minimum of 5 feet from the back of the curb. If sufficient right-of-way is unavailable in the above situations, lesser distances, 2 feet or greater, may be approved.
18.104.22.168 Open Cutting
22.214.171.124.1 The open cutting of a roadway for the purpose of working on or installing new underground facilities shall be avoided. DelDOT's policy is to avoid the open cutting of any roadway for at least five years after resurfacing or reconstruction, unless there is no alternative. Exceptions will be made only in cases of hardship as determined by the Department on a case-by-case basis.
126.96.36.199.2 The District Public Works Section shall review requests for open cutting on a case-by-case basis, and shall have final approval of how the work is to be accomplished. For work related to a DelDOT highway project, permission for open cutting shall be requested as part of the Utility Statement during the planning of the project.
188.8.131.52.3 In the event open cutting is allowed, the utility must adhere strictly to the backfill and restoration requirements. The District Public Works Section will specify fill material. Borrow type C can be utilized however; Flowable Fill is recommended for cross-road cuts. Flowable Fill may be required by the District Public Works Section. Information regarding Flowable Fill from the Special Provisions can be found in Appendix F of this manual.
184.108.40.206.4 Utilities may not cover open trenches with steel plates between October 31 and April 15. The District Public Works Section may grant exceptions.
220.127.116.11 Other Installation Methods
18.104.22.168.1 Methods of installing utilities beneath roadways, other than push-augering, jacking, and directional bore will be considered for approval only on a case-by-case basis for specific sites. The utility must prepare and submit complete plans and specifications for the excavation, design, and installation involved in other methods.
22.214.171.124.2 Other methods include tunneling and installing tunnel liners or open-cut construction involving the installation of:
All pipeline installations must conform to the applicable regulations pertaining to the type of installation being constructed. The Department considers vents, drains, markers, manholes, and shutoffs as parts of pipeline installations.
Utilities are required to give advance notice and obtain approval from the District Office for any new pipeline or anticipated change to the current design or operation of a pipeline. The permit application shall specify the applicable codes to be used. Construction permits for pipelines shall specify the class of materials being carried, transmittant, the maximum working, test, or design pressures, and the design standards for the carrier.
126.96.36.199 Placement Of Pipeline
Pipelines installed longitudinally - The pipeline must be placed as close as possible to the outer extremities of the highway, unless approved otherwise in municipality or suburban development. The placement shall not interfere with highway drainage or with the structural integrity of the travelway shoulders or embankment.
188.8.131.52.1 Pipeline Crossings:
184.108.40.206.1.1 Pipeline crossings shall not be located in deep cuts, across cuts and fills, on steep slopes, near footings of bridges or retaining wall footings, across intersections at grade or ramp terminals, in wet or rocky terrain, across drains where flows of water, drifts, or stream beds may be obstructed, or within basins of an underpass drained by a pump.
220.127.116.11.1.2 Pipe, conduit, sewer, or other similar facility must not be placed inside any drainage pipe. Neither shall objects be placed across the ends of any drainage pipe or culvert so as to obstruct the full flow of water.
18.104.22.168.1.3 Pipelines crossing streams must be securely suspended above flood lines or lay beneath streambeds.
22.214.171.124.2 Pipeline Appurtenances:
126.96.36.199.2.1 Manholes - Manholes are not to be located in the traveled way of any expressway or public way for vehicular travel. The District Public Works Section may authorize exceptions only at locations where manholes are essential parts of existing lines that have been previously authorized to remain in place. Such installations shall avoid intersections. Manholes shall be designed and located so that they will not interfere with other utilities and planned highway expansion. Manholes are not to be located in the flow line of ditches, the centerline of the roadway, or the wheel path of traffic. All manholes must be flush with the finished grade. Refer to Section 188.8.131.52 for information regarding Subdivisions.
184.108.40.206.2.2 Valves - Shut-off valves, preferably automatic, must be installed in lines at or near the ends of structures. Isolation valves will also be required near crossings of unusual hazards. Exceptions may be allowed when other safety devices placed within a reasonable distance of the structure or hazard can isolate the pipeline.
220.127.116.11.2.3 Vents - Any vents shall be located at both ends of casings longer than 150 ft and at the high end of short casings. Vent standpipes shall not interfere with maintenance, use of the highway, nor affect pedestrian traffic. The standpipes shall be highly visible and preferably located on a right-of-way line.
18.104.22.168 Hazardous Transmittants
Crossings by pipelines carrying a hazardous liquid or liquefied gas (including propane) or other hazardous or volatile material shall not be allowed. Exceptions will be made only in cases of hardship as determined by the Department on a case-by-case basis with reference to federal guidelines. Natural gas pipelines, however, will be allowed via the permit review and approval process through the District Office.
22.214.171.124 Pipeline Installation
126.96.36.199 A casing is a larger pipe, conduit, or duct enclosing a carrier. Underground utility crossings of roadways shall be made in sleeves or casings for the following conditions:
188.8.131.52.1 Utility crossings of freeways, expressways, and other controlled access highways and at other locations where it is necessary to avoid trenched construction and prevent inconvenience to highway users;
184.108.40.206.2 To protect carrier pipe from external loads or shock, either during or after construction of the highway; and
220.127.116.11.3 To prevent leaked material from saturating or damaging the highway embankment by conveying leaking fluids or gases away from the area directly beneath the roadway to a point of venting at or near the right-of-way line or to a point of drainage in the highway ditch or a natural drainage way.
18.104.22.168 When To Utilize Casings
Except for circumstances as described in Section 22.214.171.124, the Department requires that:
126.96.36.199.1 All crossings of full-access-control roadways (interstate highways, toll roads, freeways) shall be enclosed or cased.
188.8.131.52.2 All crossings of existing or proposed arterial and collector roadways (partial-access-control roadways) shall be enclosed or cased. Arterial and collector roadways are identified on the DelDOT Functional Classification Maps.
184.108.40.206.3 Casings are required for crossings of existing or proposed major entrances to commercial facilities or residential subdivisions. However, if an exception is granted, at such locations the minimum design shall be the same as the design requirements outlined in Section 220.127.116.11, or as approved by the District Public Works Section.
18.104.22.168.4 Typically, jacked or bored installations of coated carrier pipes shall be cased unless assurance can be provided against damage to the protective coating.
22.214.171.124.5 Consideration shall be given to encasement or other suitable protection for any pipeline
126.96.36.199.5.1 with less than minimum cover,
188.8.131.52.5.2 near footings of bridges or other highway structures
184.108.40.206.5.3 across unstable or subsiding ground, or
220.127.116.11.5.4 near other locations where hazardous conditions may exist.
18.104.22.168 Exceptions To Casings
22.214.171.124.1 Suitable bridging, concrete slabs, or other appropriate measures should be used to protect existing uncased pipelines which by reason of shallow cover or location make them vulnerable to damage from highway construction or maintenance operations. Such existing lines may remain in place without further protection measures if they are of adequate depth and do not conflict with the highway construction or maintenance operations, provided both highway and utility officials are satisfied that the lines are, and will remain, structurally sound and operationally safe.
126.96.36.199.2 Uncased construction can be employed if approved by District Public Works for permit work or the Utilities Engineer during highway construction projects. The approval is acceptable when open cutting is approved, if necessary, and in the following circumstances:
188.8.131.52.2.1 The carrier is approved by the Department and conforms to the material and design requirements of the utility industry, governmental codes and standards, can support the load of the highway plus loads superimposed thereon when the pipe is operated under all ranges of pressure from maximum internal to zero pressure, with a higher factor of safety than normally required for cased construction. Carriers meeting these requirements can be used for the following installations provided a profile is submitted along with the plans for the following types of installations:
184.108.40.206.2.1.1 Natural Gas - utilities can employ welded steel pipe or high density polyethylene pipe (HDPE) as an uncased carrier pipe with at least 42 inches of cover. All such pipes shall meet design requirements as outlined above. The design of the HDPE pipe will also meet the minimum requirements referenced in the table in Appendix L.
220.127.116.11.2.1.2 Sewer - utilities can employ high density polyethylene pipe as an uncased carrier pipe. All such HDPE pipes shall meet design requirements as outlined above. The design of the HDPE pipe will also meet the minimum requirements referenced in the table in Appendix L.
18.104.22.168.2.1.3 Water - The minimum requirements for waterline crossings shall be ductile iron pipe with an industry standard push joint and at least 42 inches of cover. All such ductile iron pipes shall meet design requirements as outlined above.
22.214.171.124.2.2 Other Transmittants: A Department approved uncased crossing of welded steel pipelines carrying a transmittant which is flammable, corrosive, expansive, or unstable materials, particularly if carried at high pressure, may be permitted, provided additional protective measures are taken in lieu of casing. Such measures would employ higher factor of safety in the design, construction, and testing of the uncased carrier pipe, including such features as thicker wall pipe, radiograph testing of welds, hydrostatic testing, coating and wrapping, and cathodic protection
126.96.36.199.3 Suitable bridging, concrete slabs, or other appropriate measures shall be used to protect existing uncased pipelines which by reason of shallow cover or location make them vulnerable to damage from highway construction or maintenance operations.
188.8.131.52.4 Any exceptions (aside from 1a,1b, and 1c) to the casing requirements shall be determined by the District Public Works Section, based upon a written request for the exception stating the hardship and proposed method of crossing. In requesting exceptions, the utility shall consider the Department's policy of no open cutting of a roadway within 5 years after it has been resurfaced, except for an emergency. In addition, there shall be no open cutting for service lateral crossings. Utilities shall also consider those areas where repairs would be restricted by lack of rights-of-way or easements.
184.108.40.206 Permits For Casings
In all situations where a casing is to be installed, the utility shall submit a plan describing the location, method, and type of casing for approval by the District Public Works Section.
220.127.116.11 Placement Of Casing
18.104.22.168 Where casings are required, the location of the crossings must be determined carefully so that, if necessary, the utility can acquire sufficient right-of-way or private easements to remove or replace the utilities.
Casings shall extend at least 5 feet beyond the curb, pavement, projected fill slopes, or ditch lines to assure proper support of roadways during any repairs to pipelines. For all access-controlled highways, the encasement shall extend from right-of-way line to right-of way line or outside outer curbs. The design shall encompass allowance for future widening of the highway without the need of utility adjustment.
22.214.171.124 Types Of Casing
Casings shall be designed to support the load of the highway and superimposed loads thereon and at least equal the structural requirements for highway drainage facilities. Corrugated materials shall not be allowed.
126.96.36.199.1 Volatile Transmittant - The casings for facilities transmitting volatile materials must be of steel pipe or high density polyethylene of standard manufacture. The design of the HDPE pipe will also meet the minimum requirements referenced in the table in Appendix L. The joints must be welded or fused sealed around the entire circumference of the pipe as industry standards and regulations allow.
188.8.131.52.2 Non-Volatile Transmittant - The casings for facilities transmitting non-volatile materials may be of standard material such as steel pipe or high density polyethylene. The design of the HDPE pipe will also meet the minimum requirements referenced in the table in Appendix L. Other usable materials must be of a design to sustain the live and dead loads currently used in Delaware highway design. Such materials include reinforced concrete pipe, cast iron pipe, aluminum pipe, high density polyethylene pipe and ductile iron pipe.
184.108.40.206 Casing Installation
220.127.116.11.1 All pipeline installations must conform to the applicable regulations pertaining to the type of installation being constructed. When a pipeline casing is placed under a roadway, all installations are to be made by jacking, push-augering, or other approved methods. If coated pipe is used for jacking or boring, the same pipe should not be used as a carrier pipe.
18.104.22.168.2 A typical layout for jacking through a roadway is shown in Figure 2-1. Appropriate traffic control measures shall be used in accordance with DelDOT's Traffic Control Manual due to the reduction in shoulder use by the traveling public caused by jacking operations.
22.214.171.124.3 Other requirements for installation are as follows:
126.96.36.199.3.1 Non-Metallic Pipe - Installations of non-metallic pipe must include a tracer material that is detectable by locating devices that are acceptable within the industry.
188.8.131.52.3.2 Depth of Casing - The minimum cover required over casings is 42 inches, as measured from the top of the casing. The critical control for the depth of cover on a non-cased pipeline crossing is the low point in the highway cross-section. Normally, this is the bottom of the longitudinal ditch. Additional protection shall be provided for any pipeline with less then minimal cover.
184.108.40.206.3.3 Clearances - All utilities shall be separated from one another as required by appropriate codes and ordinances.
220.127.116.11.3.4 Sealing of Casing - Casing pipe over 4 inches in diameter must be sealed. Where carrier pipes that carry combustibles are cased, the casing pipes must be provided with a screened vent on each end that is as near as feasible to the right-of-way boundaries.
18.104.22.168.3.5 Drains - Drains shall be provided for casings and tunnels enclosing carriers of liquid, liquefied gas, or heavy gas. Drains may not outfall into roadside ditches. Such outfall shall not be used as a wasteway for purging the carrier unless specifically authorized by a National Pollutant Discharge Elimination System (NPDES) permit.
22.214.171.124.3.6 Vents - Where carrier pipes that carry combustibles are cased, the casing pipes must be provided with a screened vent on each end that is as near as feasible to the right-of-way boundaries. Other requirements are as follows:
126.96.36.199.3.7 Vents required for cased pipes are to be located at the high end of short casings-less than 150 feet long-and at both ends of casings longer than 150 feet.
188.8.131.52.3.8 Vent standpipes and warning markers are to be located and constructed so as not to interfere with the maintenance of the highway nor be concealed by vegetation.
2.6.5 Electric, Communication, And CATV
184.108.40.206 The requirements discussed earlier in this chapter describing installations and maintenance of pipelines crossing highway rights-of-way-as related to casings, markers, and installations- must also be applied to underground electric, CATV, and communications lines two inches or larger. The minimum depth of cover for these cased crossings is 42". Greater cover may be required depending on the construction of the roadway.
220.127.116.11 For underground electric, CATV, and communications lines less than two inches in diameter:
18.104.22.168.1 Where a conduit or casing is placed under an existing roadway, all installations must be made by jacking, push-augering, directional bore or other approved methods. The casing must have a minimum nominal diameter of 2 inches and is to be placed a minimum of 24 inches below the surface. The utilities must also conform to the National Electric Safety Code and any other utility codes cited in Section 2.4. Utilities may be required to install facilities deeper on a case by case basis depending upon the construction of the roadway.
22.214.171.124.2 Where the burying of cable is permitted along the edge of pavement, it may be done by plowing or trenching methods. The nearest edge of the trench must be at least 5 feet from the edge of the pavement, however, this distance can be reduced to 2 feet or greater should sufficient right-of-way be unavailable. The minimum depth of bury for CATV, communications, and electric is 24 inches, however, these utilities must also conform to the National Electric Safety Code and any other applicable regulations.
2.7 Attachments To Structures
126.96.36.199 Attaching utility lines to a highway structure can materially affect the structure, the safe operation of traffic, and the efficiency of maintenance, safety inspections, and structural repairs.
188.8.131.52 New attachments of utility facilities such as water, gas, sanitary sewer mains and electrical facilities will not be allowed to be attached to new structures. Communications and other telecommunications will not be permitted unless an extreme hardship can be proven. If a utility believes there is no feasible alternative, it must submit a written request to the district. In the request, the utility must include the proposed cost of the installation, describe other alternatives, and detail the associated costs of those alternatives. The District Public Works Engineer, Bridge Design Engineer, and Utilities Engineer and District Public Works will use the information in making a decision. The request is also subject to the approval of the Assistant Director, Design and Chief Engineer. Wheren utility attachments are indicatedrequested, they will be considered only if the structure in question is of a design that is adequate to support the additional load and to accommodate the utility facility without compromise of highway features, including reasonable ease of bridge maintenance. In all cases, gas lines or pipelines carrying explosive, corrosive, or flammable fluids must follow all applicable Federal and State codes.
184.108.40.206 The Department may enter into an agreement to reimburse the utility to design and inspect facility support and protection during Department projects as described in Chapter 4. Refer to the OSHA Technical Manual for requirements.
2.7.2 Request For Attachment
220.127.116.11 In extreme hardship cases, the utility shall submit to the Utilities Section Engineer a written request to attach its facility to a structure owned and maintained by DelDOTDistrict Public Works. The request shall include the following items:
18.104.22.168.1 Identification of the structure including details regarding the utility facility and its contents, such as pressure, voltage, current, flammability, freeze point, weight per foot, and any other pertinent information.
22.214.171.124.2 Calculations performed by a Delaware registered professional engineer to demonstrate the structural impact on the existing structure. All hazardous impacts must be addressed-magnetic fields, protection against electrocution, etc.
126.96.36.199.3 A study identifying alternate methods of getting the facility over, under, or around the obstacle, as well as the costs and problems associated with each alternative.
188.8.131.52.4 Descriptions of the proposed method of attachment and the appropriate devices for protecting the bridge and the facility.
184.108.40.206.5 The costs of the design and/or increased construction expenses, including the utility's commitment to pay for the construction expenses.
220.127.116.11 The request for attachment shall then be reviewed and approved by the District Public Works Engineer, Utilities Engineer and the Bridge Design Engineer. The request is also subject to the approval of the Assistant Director, Design and Chief Engineer.
18.104.22.168 Utilities are expected to make a good-faith effort to accommodate DelDOT maintenance or construction requirements. The Utility shall submit all material and construction specifications for inclusion in contract documents for any work to be performed by DelDOT's contractor.
2.7.3 New Construction
If the Department approves the attachment, the utility must commit agree to havingallow the facility installed by the Department's contractor at the price assigned to this bid item within the Department's construction project bid, at the utility's expense. The utility shall reimburse the Department in accordance with the terms of an agreement outlining the conditions of bridge occupancy.
2.7.4 Existing Structures
The following policies apply to utilities on existing structures:
22.214.171.124 Existing utilities attached to a structure can remain if they are not impacted by a Department project.
126.96.36.199 Existing utilities must be relocated off the structure if the Department's project requires either temporary or permanent relocation.
188.8.131.52 Any utility that plans to replace a facility attached to a structure shall relocate the facility off the structure.
184.108.40.206 The utility must consult the Department District Public Works on its choice of contractor, and have the Department's District Public Work's consent. The utility, by agreement, shall pay for Department inspection, and the Department shall have an inspector on site during the construction.
2.7.5 Attachment Procedures
The following should be considered when the design of utility attachments is reviewed:
220.127.116.11 The attachment is designed to minimize adverse impact on structure maintenance.
18.104.22.168 No facilities are attached to the outsides of structures.
22.214.171.124 All utility facilities attached to structures shall be housed in casing pipes to allow for insertion and extraction of the carrier facility.
126.96.36.199 No manholes are constructed in bridge decks.
188.8.131.52 Utilities are placed so that the vertical clearance of the bridge above the stream, pavement, or railroad tracks is not reduced.
184.108.40.206 Utilities are located beneath decks, between the outer girders or beams, and within a cell -above the low superstructure steel or masonry.
220.127.116.11 Support rollers, saddles, or padded or coated hangers are used to muffle vibration noise.
18.104.22.168 The casings of pipes or conduits that are carried through bridges, or attached to them, are effectively opened or vented at each end to prevent pressure buildups and detect gas or fluid leaks. Casing pipes shall be sealed at the ends with a flexible material to prevent flowing water or debris from entering the annular space between the casing and carrier. Casing drains shall be provided for a carrier of liquid, liquefied gas, or heavy gas.
22.214.171.124 Additional protective measures are taken where pipes or conduits carried through or attached to structures are not cased. Such measures shall employ a higher safety factor in the design, construction, and testing of the pipeline than would normally be required for cased construction.
126.96.36.199 Upon leaving bridges, the utilities are aligned outside the roadway in as short a distance as operationally practicable.
188.8.131.52 Hangers or rollers are suspended from inserts below deck or from hanger rods clamped to beam flanges. No bolting through bridge floors or beams should be allowed.
184.108.40.206 Where appropriate, the linear expansion and contraction of utilities due to temperature changes are provided for. Line bends or expansion couplings should be used.
220.127.116.11 Suitable corrosion protection is provided.
18.104.22.168 Communication and electric lines that are attached to structures, or pass through them, are suitably insulated and grounded, and are carried in protective conduit or pipe from the point of exit from the ground to re-entry. Carrier pipe and casing pipe shall be suitably insulated from electric power line attachments.
22.214.171.124 Pipes and conduits that are carried through abutments are sleeved and tightly sealed with mastic, or carried through by other approved methods.
2.8 Preservation And Restoration
126.96.36.199 Utilities are prohibited from spraying, cutting, and trimming trees on public highways or street rights-of-way unless written permission has been granted by the Department. When permission is granted for a utility to cut or trim trees, the work must be performed in compliance with Department standards.
188.8.131.52 Where tree removal is permitted, stumps must be removed, and the resulting holes shall be properly backfilled to allow for settlement in accordance with the DelDOT Standard Specifications.
184.108.40.206 The Department has adopted the ANSI Standard A300 (Part 1)-2001 entitled Tree Care Operations - Tree, Shrub and Other Woody Plant Maintenance - Standard Practices. The Landscaping and Reforestation Act Implementation (located in Appendix A of the DelDOT Road Design Manual) also provides guidelines for tree protection and maintenance during road construction projects.
220.127.116.11 For all future transportation projects and maintenance activities on existing highway alignments, trees must be replaced in accordance with the Department's Landscaping and Reforestation Act Implementation located in Appendix A of the DelDOT Road Design Manual. Each employee or agent of the Department who participates in the planning, design, and construction of projects and normal maintenance of the roadways should be aware of the aesthetic and environmental effect that natural vegetation provides. Every effort must be made to preserve the beauty of Delaware's roads. However, each employee or agent must also be aware of the danger posed by hazards left along the roadside. The AASHTO Roadside Design Guide should be used as reference. The traveling public has the right to expect a reasonably safe road and roadside area when faced with potential dangers such as blowouts, evasions of other vehicles or animals, adverse weather conditions, and other uncontrollable situations.
18.104.22.168 Utilities shall ensure that appropriate erosion control devices are in place before work starts and properly maintained during construction. The surface area disturbed by utility installations or relocations shall be kept to a minimum.
Care shall also be taken in utility installations to avoid disturbing existing highway or private drainage facilities or sprinkler systems. Any damage to the facilities by the utility company or its subcontractors shall be repaired at the utility company's expense.
22.214.171.124 Damage to highway traveled ways, shoulders, and drainage features caused by utility installations or repairs must be immediately restored to their original condition as stated in the Delaware Code. If utilities have not completed restoration within 30 days, noncompliance regulations will take effect. Temporary patches from winter months shall be permanently restored by May 15 before noncompliance action will be taken. Damage to roadside areas in the right-of-way shall be repaired as soon as possible, or as specified by the District Public Works Section. Restoration is also necessary when utilities are working on active construction sites. The District Public Works Section will determine any necessary repairs.
126.96.36.199 The utilities shall restore the damaged areas to a condition at least equivalent to that which existed prior to the utility work. In all cases, the District Public Works Section will determine the extent of restoration required. All such work will be done at the utility's expense and in accordance with the appropriate Standard Specifications. The Seeding specification is located in Section 734 of the Standard Specifications.
188.8.131.52 The utility shall maintain the non-pavement restoration for a period of 12 months after the satisfactory completion. Utilities are responsible for maintaining pavement patches that result from utility work for three (3) years.
2.8.3 Traveled Way-general
To maintain traffic, not more than one lane of traffic shall be closed at a time whenever a traveled way is cut. All cross-road cuts for utilities will be made perpendicular to the longitudinal centerline of the traveled way, and perpendicular to the plane of the finished subgrade. All patches must have a minimum length of 6 feet (as measured along the roadway centerline) and the width of the lane or lanes disturbed. Any lane encroachment of one foot or more requires restoration of the full lane width. Before reopening the section, the area shall be made usable for traffic. DelDOT Standard Construction Detail P-2 illustrates cross-road cuts.
2.8.3 Flowable Fill
Flowable fill is recommended for restoration of cross-road cuts although Borrow Type C can be utilized. Flowable fill shall meet the requirements of Special Provision 208500 as shown in Appendix F. The District Public Works Section may require flowable fill.
2.8.4 Temporary Patches
184.108.40.206 If immediate repairs to the traveled way are not feasible-and if the District Public Works Section concurs-a temporary patch may be used until permanent repairs are completed. Figure 2-3 shows the minimum design requirements for temporary patches: at least 8 inches of compacted graded aggregate overlaid by at least 2 inches of Superpave Type C 160 Gyration, PG 64-22. When weather conditions prohibit the use of such mix, District Public Works can approve 10 inches of compacted graded aggregate overlaid by at least 2 inches of cold patch mix.
220.127.116.11 Figure 2-3 also illustrates trench width and backfill layer requirements. Backfill shall be placed and compacted in successive layers. Trench widths vary, but should not be less than 2 feet plus the outside diameter of the pipe. Each backfill layer is to be placed in a level, uniform cross section not exceeding 8 inches in loose depth, and then compacted with a mechanical tamper according to the Standard Specifications Division 200 regarding Earthwork.
2.8.5 Surface Treatments And Hot Mix Pavements
18.104.22.168 Firgure 2-4 illustrates the details of permanent cross-road or longitudinal utility patches for surface-treated or hot mix asphalt roads and shoulders. Note that this is a minimum patch. If the existing roadway has a heavier cross section than indicated in Figure 2-4, it will be replaced with the same cross section or as directed by the District Public Works Section.
22.214.171.124 The compaction requirements for both the patch material and the backfill material are covered in Division 200 of DelDOT's Standard Specifications.
126.96.36.199 The details for a temporary patch are shown in Figure 2-3.
2.8.6 Portland Cement Concrete Pavements
188.8.131.52 Portland cement concrete (PCC) streets and roads must be patched as described in Section 503-"Patching Portland Cement Concrete Pavement"-of the Standard Specifications. The details are shown in the DelDOT's Standard Construction Detail P-2 for PCC Pavement Patching.
184.108.40.206 An approved concrete saw shall be used to make a vertical, full-depth cut in the concrete pavement. The cut is to be made to ensure a straight, clean, vertical surface.
220.127.116.11 Temporary patches are discouraged in PCC pavements in favor of plating the opening and returning the next day to pour permanent ones. If a temporary patch is to be used, it will require the same cross section as shown in Figure 2-3 (8 inches graded).
18.104.22.168 Other details of utility patches in PCC pavements are shown in Standard No. P2 of DelDOT's Standard Construction Details.
2.8.7 HOt Mix Overlays On Pcc Pavements
Utility patches made in PCC pavements with hot mix overlays shall comply with the current Standard Specifications and gain approval of the District Public Works Section. The patch layout is illustrated in Standard No. P2 of DelDOT's Standard Construction Details.
22.214.171.124 Damage to roadside areas in the right of way shall be repaired as soon as possible to conditions at least equivalent to those existing prior to utility work. The restoration of roadside areas is concerned mainly with trenching and backfilling requirements. First, excavation widths will vary depending on the type of utility being placed.
126.96.36.199 Trenches for cables, conduits, conductors, or pipes-other than those that are plowed or cut by a small trencher with a 4-inch to 6-inch cut-must be at least 8 inches wide.
188.8.131.52 Trenches for pipe (other than rectangular or square conduit) with an outside diameter of 6 inches or more must be cut 2 feet wider than the outside diameter of the pipe. The pipe will then be placed in the trench with a 1-foot clearance on each side.
184.108.40.206 Trenches are to be backfilled or covered immediately after installation of the utility facility. They cannot be left open overnight because they pose a hazard to the public. Authorization to use steel plates at any time other than April 15 through October 31 must be obtained from the District Public Works Section.
220.127.116.11 Acceptable material must be used to backfill trenches. It shall be placed in 8-inch layers (loose measurement) and thoroughly compacted-just as for trenches in pavement areas. The backfill material and compaction method must meet the requirements of the Standard Specifications.
18.104.22.168 Excavated material that is not satisfactory for backfill shall be removed from the area immediately after excavation. Material that is satisfactory for backfill must be stockpiled in a safe and orderly manner-preferably not stored on the roadway. District Public Works can approve storage on the roadway if necessary. Material stockpiled in the immediate work area must not pose a hazard to the traveling public. All materials shall be stockpiled in accordance with the rules established by the Manual on Uniform Traffic Control Devices (MUTCD).
2.8.9 Manholes And Valve Boxes
22.214.171.124 Where manholes or valve boxes are repaired in pavement areas, backfill shall be placed in 8-inch layers (loose measurement) and thoroughly compacted-the same as for trenches in pavement areas. The backfill material (Type C Borrow) and compaction method must meet the current Standard Specifications.
During construction, areas around manhole lids and valve boxes must be dug by a non-destructive method. The details of proper roadway patching around manhole lids are shown in Figure 2-5.
2.8.10 Test Holes
126.96.36.199.1 When possible, test holes are to be dug by a nondestructive method-such as by vacuum removal in a hole less than 244 square inches. The repair shall be only the size of the hole. The fill shall be compacted in lifts, and the same amount of stone, hot mix, concrete, etc.- as the existing roadway-shall be replaced.
188.8.131.52.2 Sometimes small holes (up to 2 inches in diameter) bored in the surface for any type of utility testing or maintenance will be repaired with a flexible embedding sealer (cold poured resilient type epoxy joint sealer) approved by the District Public Works Section.
2.8.11 Highway Construction Projects
184.108.40.206 The restoration requirements defined in Sections 220.127.116.11 through 18.104.22.168 apply to the placement of utilities on existing roadways and rights-of-way. Where utility relocations and adjustments are made in conjunction with a highway improvement project, some portions of the restoration by the utilities may be unnecessary. For example, full restoration is unnecessary when the area will be repaved as a part of the highway improvement. Under these circumstances, appropriate portions of the restoration requirements may be waived.
22.214.171.124 The utility is responsible for restoring all sedimentation and erosion control measures to their original conditions and for maintaining temporary patches.
3.1 Definitions and General Requirements
The Department uses three different types of documents to manage the installation and/or occupancy of utility facilities on, under or across State right-of-way. These documents include franchises, permits, and agreements.
Public Utility Annual Master Franchise - The Public Utility Annual Master Franchise is a legal instrument that grants the use of highway rights-of-way. It authorizes a public utility to place its facilities within State rights-of-way without any vested interest therein (under the provisions of Title 17 of the Delaware Code). A franchise does not serve as a control instrument over construction methods, traffic control features, or timing as opposed to a permit, which does. The only type of franchise accepted by the Department is the Public Utility Annual Master Franchise established October of 2004. The Master Franchise eliminated the need for a public utility to apply for a franchise each time a new utility installation was to be located within State right-of-way. The public utility applies for a Master Franchise for each County where it owns facilities within the State right-of-way. The executed Master Franchise remains in force for a period of 50 years and automatically renews annually for another 50 years unless otherwise agreed to by the parties.
Use and Occupancy Agreement - This agreement is between the Department and an individual or entity for a privately owned utility that crosses a State-maintained road. It provides the Department with information about the crossing and sets forth the conditions for it. This agreement may also be used for privately or individually owned facilities to be located on State rights-of-way.
Utility Construction Permit - A Utility Construction Permit authorizes a utility to construct, maintain, or repair a utility facility within State rights-of-way. The highway is under the control of District Public Works, and a Utility Construction Permit is used to secure the District Public Works Section's approval of the details controlling construction activities.
Letter Agreement - A letter agreement is a legal instrument between a utility and the Department to establish the utility work in conjunction with a DelDOT highway construction project that the Department has determined to be reimbursable. It describes the terms and conditions-in accordance with the State code-by which the work and subsequent payment will be handled. An executed letter agreement is required prior to the performance of any work that is to be reimbursed. See Chapter 4 for further discussion.
3.1.2 General Requirements
A Master Franchise is required if a public utility locates facilities on State right-of-way. A public utility must submit a franchise application for each County where its facilities are located within the State rights-of-way.
A Utility Construction Permit is required in all cases of maintenance or installation of utility facilities on State right-of-way, including right-of-way within a municipality unless otherwise specified for a State Highway Construction Project. A Master Franchise or a Use and Occupancy Agreement must be in force before a construction permit is valid. The application for a Utility Construction Permit must be submitted to the applicable District Office of Public Works.
A Utility Construction Permit may not be issued to place aboveground or underground parallel facilities along both sides of a traveled way, unless justified and approved by the District Public Works Section or located within subdivisions. In the case of underground, safety and adequate space for other utilities should be considered before exceptions are approved.
If the utility crosses over or under a railroad, the District will make a notation on the permit that the work is subject to approval by the railroad company. A copy of the railroad company approval shall be supplied upon request to the District prior to crossing the railroad.
3.2 Master Franchise
The Master Franchise is a legal instrument by which the use of highway right-of-way is granted. It is not a control instrument over construction methods, traffic control features, or timing as opposed to a permit. The Department may grant a Master Franchise to the following utilities:
126.96.36.199 a public utility subject to the regulatory jurisdiction of the Public Service Commission;
188.8.131.52 a cable system operator or video services provider franchised by the Public Service Commission or a municipality; or
184.108.40.206 a utility owned, operated, controlled or created by the State, a municipality, county, or other political subdivision.
The Public Utility Annual Master Franchise form is located in Appendix B of this manual.
The Master Franchise requires that all facilities to be constructed must meet the requirements set forth in this manual for locations, construction, construction methods, timing, etc.
The utility submits three Master Franchise forms for each County where they own facilities in the State rights-of-way. The three forms shall be signed with signature attested and the Company seal affixed. The franchise forms are to be submitted to the Utilities Engineer's office for processing.
The appropriate Utility Coordinator reviews the Master Franchise forms for accuracy and completeness. If satisfactory, DelDOT Deputy Attorney General, Assistant Director of Engineering Support, and the Director of Technology and Support Services will execute the agreement and affix the Departmental seal. An original will be returned to the utility, one is forwarded to the DelDOT Director of Technology and Support Services, and one is retained in the Utilities Section. A copy of the Master Franchise will be forwarded to the appropriate District.
Each Master Franchise remains in effect for 50 years from the date of execution by the Department. The Master Franchise shall automatically renew annually for another 50 years unless otherwise agreed to by the parties. There is no need to file the franchise application annually.
Upon completion and acceptance of the subdivision or industrial streets, the utilities that are located within the State right-of-way shall be franchised in accordance with the existing countywide Public Utility Annual Master Franchise for each individual utility. Future work performed in that development will require only a utility construction permit. Please refer to the Standards and Regulations for Subdivision Streets and State Highway Access for requirements regarding subdivisions.
3.2.7 Freeway Right-of-way
220.127.116.11Only in exceptional cases are utilities granted a Utility Construction Permit to cross freeway right-of-way on new locations, and rarely are they permitted to run longitudinally on freeway right-of-way.
18.104.22.168 A utility will be permitted along a freeway on a new location only under strictly controlled conditions. An application for permission to use or occupy the freeway right-of-way must be directed to the District Public Works Section.
22.214.171.124 The application must address the following:
126.96.36.199.1 the direct and indirect environmental and economic effects of any loss of productive agricultural land which may result from disapproving the use of the right-of-way,
188.8.131.52.2 the utility's compliance with the provisions of this manual and AASHTO policies as referred to in Appendix D,
184.108.40.206.3 why any other utility location would be extremely difficult and unreasonably costly for the utility consumer and
220.127.116.11.4 how the utility's installation on the freeway right-of-way will not adversely affect the design, construction, stability, traffic safety, or operation of the freeway.
18.104.22.168 The District Public Works Section will assess the situation and send the application with a recommendation and justification to the Utilities Engineer for coordination and comment. The Utilities Engineer will then review the application and provide the necessary coordination. Next, the application will be sent to the Assistant Director, Engineering Support for review.
3.2.8 Coordination Between Utility and State
Both the Department and the utility company representatives need to exchange information regularly to help avoid conflicts between utility company projects and Department projects in terms of location, construction, or method of installation.
3.3 Use and Occupancy Agreements
The Use and Occupancy Agreement (shown in Appendix B) is to be used for privately or individually owned facilities that are located on or across a State-maintained roadway. For example, if a landowner owns both sides of a State roadway and needs to convey irrigation lines, water lines, gas lines, etc., between the properties, the landowner and Department must execute a Use and Occupancy Agreement.
The Utility Use and Occupancy Agreement provides the Department with information about the facilities and sets forth their conditions. The owner must obtain a Utility Construction Permit for any construction, maintenance, or repair.
The Use and Occupancy Agreement provides the Department with information about the crossing and sets forth the conditions for the facilities. Only crossings will be allowed; longitudinal lines will not be permitted.
Signs will be provided by the Department to mark the utility crossing at each right-of-way line. Furnishing the mounting post and installation in accordance with Department requirements is the responsibility of the utility owner.
A Use and Occupancy Agreement must be prepared by the owner, in triplicate, for each installation where a facility is placed on a State-maintained roadway.
The Utility Use and Occupancy Agreement is then processed according to the following steps:
3.4 Construction Permits
A Utility Construction Permit form (Appendix B) must be completed for all utility construction not performed in conjunction with a DelDOT construction project. A permit is required if utility work is done in advance of the construction project where DelDOT Construction has not yet been assigned. The permit is used to secure the District Public Works Section's approval of the details controlling construction activities. An executed Public Utility Annual Master Franchise shall be on file prior to submission of a construction permit application for Public Utilities. A privately owned facility must have a Utility Construction Permit and a Use and Occupancy Agreement before any type of installation, repairs or relocation.
To apply for a permit, contact the appropriate District Public Works Office:
North District: Area north of and including I-95 and I-495 (except area west of Route 7, south of Route 2), including the City of Wilmington.
Canal District: Area south of I-95 and I-495 (including west of Route 7 and south of Route 2 to Kent County, including the City of Newark.)
Usually, four sketches or plans must be attached to the construction permit application upon submittal. However, it is best to contact the District to see if there have been any changes to the requirements.
3.4.2 Electronic Permits
A computerized permit process intended for large users may supplement the construction permit process. The utilities wishing to use the system will need to execute a letter agreement with the Department specifying the conditions of the electronic permits.
A Utility Construction Permit is required any time utility construction work (including excavations or openings) will disturb anything on the roadway or State right-of-way. The permit is necessary each time a facility is upgraded or rebuilt, or an installation is added (excluding services). Project Design Work (as defined in Section 2.1) is excluded from this requirement except in cases when Utility Work is performed in advance of construction or the Department requests test holes for the locations of utilities. The District may waive the permit requirement for test holes.
Permits for Public Utilities will be issued only if a Master Franchise is in force. Private owners of facilities must have a Use and Occupancy Agreement along with a permit. The new permit request must show the existing and proposed installation.
A utility that performs work on the State right-of-way longer than one working day to repair or adjust an existing facility-or that disturbs the roadway-must have a construction permit. If the work takes less than one day, and does not disturb the roadway, a permit is not required. However, the utility must notify the District Public Works Office of any lane closure on any roadway outside of a subdivision before starting work. The notification must include the location and type of work to be performed.
In an emergency, the utility must promptly notify the District Public Works Office. The utility is responsible for communicating the type of emergency and location of the work to be performed and other pertinent information. The utility must submit a construction permit to the District Public Works Office as soon as possible. In case of an emergency during normal business hours, call the District Public Works numbers listed in Section 3.4.1. After normal business hours, please call:
New Castle County: 302-323-1111
Kent County: 302-760-2473
Sussex County: 302-855-1111
No fees are authorized at this time.
22.214.171.124 Utility Construction Permits are to be prepared in four copies (unless submitted electronically) by the utility company and submitted to the office of the District Public Works Section along with four copies of plan. The sketches or plans must show the:
126.96.36.199.1 width of the right-of-way,
188.8.131.52.2 type of roadway,
184.108.40.206.3 width of traveled way,
220.127.116.11.4 distance from the crossroad or side road to the installation,
18.104.22.168.5 distance from the centerline of the roadway to the installation,
22.214.171.124.6 type of shoulder,
126.96.36.199.7 width of shoulder,
188.8.131.52.8 drainage system in the utility area,
184.108.40.206.9 trench and restoration details,
220.127.116.11.10 north arrow, scale and legend, and
18.104.22.168.11 railroads crossing roadways.
22.214.171.124 In addition, all sketches for pressure pipeline installations must specify the class of transmittant, the maximum working pressure, the maximum design pressures, and the design standards for the carrier.
126.96.36.199 When a Utility Construction Permit is needed after a DelDOT highway contract has been awarded, the utility must obtain written permission from the DelDOT contractor to work in the project area. This policy includes any utility work not caused by the construction or improvement of a highway. For an exception to be made, the utility must have written permission from DelDOT to perform such work. To give this written permission, DelDOT must first obtain a satisfactory waiver, release, and quit claim from the State's contractor. It must cover all damages and all defenses whatsoever for delays caused by the utility work. If a dispute arises or the contractor will not provide the appropriate document, then the District Public Works Section has the option of setting a time frame in which the utility may work.
The Utility Company submits a permit application to the District Public Works Office. The District assigns a permit number and distributes the originals as follows:
Utility Construction Permits are required for work to be performed on state right of way or state maintained roads within the incorporated limits of a municipality. The utility must also have approval of the municipality.
3.5 Utility Construction, Relocation, Or Repair Not Due To Highway Construction
3.5.1 A public utility must not start construction of a new installation, repairs, or relocation until a Utility Construction Permit has been issued and a Master Franchise is in force. A privately owned facility must have a Utility Construction Permit and a Use and Occupancy Agreement before any type of installation, repairs or relocation.
3.5.2 The District Public Works office must be notified at least one working day before the start of construction. (Notification may be given in writing, orally, or by fax.) The information transmitted must include the starting date, road number, and permit number. Refer to Section 3.4.3 for further details including emergency situations.
3.5.3 Permits issued by the State may be revoked whenever state authorities ascertain a threat to the traveling public. Other causes for revocation may include--but may not be limited to--misuse, noncompliance with State requirements, or improper maintenance of traffic. Depending on the circumstances, any permit application may be denied.
3.5.4 The utility company or its contractor must have a responsible representative at the job site at all times to supervise the work. Information on the Utility Construction Permit must be available to this responsible representative.
3.5.6 Utilities must notify "Miss Utility" at least two working days before starting work. A "working day" shall mean every day, except Saturday, Sunday and state, federal and recognized operator holidays.
3.6.1 If a utility fails to comply with any of the conditions, restrictions, or regulations prescribed by DelDOT and stated in this manual, the following actions will be taken:
188.8.131.52 The State will notify the utility, in writing, of the noncompliance. The State may also impose such actions, as it may deem appropriate, including an immediate stop work order until the utility complies.
184.108.40.206 The utility must correct the noncompliance within 30 days after receiving written notice from the State.
220.127.116.11 After the thirty 30 day period, the State will be required to take any action necessary to protect the safety of the traveling public. This may include restoration of roads or taking possession of and removing poles, pole lines, wires, pipelines, conduits, fixtures, or other structures or property owned by the utility and located on State right-of-way.
18.104.22.168 The utility will be responsible for all costs and expenses associated with the necessary action to correct the situation.
4.0 Utility Adjustments for Highway Construction
Existing utilities along highways that are to be reconstructed may sometimes be allowed to remain in place, however they usually must be adjusted or relocated to accommodate the construction work and the reconstructed highway.
Utility facilities must not be in the way of the reconstruction work in order to remain in place. In addition, their future maintenance must not create a hazard for the traveling public. The Utilities Engineer shall determine whether they may remain in place.
In general, utilities are not reimbursed by the State for the cost of adjusting or relocating their facilities. In accordance with Section 143, Title 17, Delaware Code, however, some work is reimbursable. Both cases are discussed in this chapter.
4.1 Preconstruction Coordination
The Utilities Section shall manage coordination of the design process for utility relocations and adjustments associated with highway construction projects. Utility companies shall provide information to the Department for all of their facilities within the existing or proposed right-of-way. The information provided will include the facility types, sizes, and locations.
4.1.1 Concept Phase
In the concept phase, the Department Project Manager is responsible for defining the limits of the right-of-way necessary to construct, operate, maintain the highway and plan for utility relocation. To minimize design time and avoid costly revisions, the Project Manager shall consult with the Utilities Section early in the design process. The Project Manager collaborates with the assigned Utility Coordinator to determine potential utility impacts. The Project Manager and Utility Coordinator shall determine the extent and timing of utility designation.
The Utility Coordinator identifies existing utilities and contacts existing utility companies as necessary. The utility companies shall submit any easement or "prior rights" documentation to the Utilities Engineer. The purpose of the submittal is to establish a compensable interest if the utility is seeking reimbursement in accordance with Delaware Code. An executed agreement between the Department and the utility shall be in place for all eligible adjustments before any utility work can begin. Refer to Section 4.3 for more information regarding agreements.
Note: It is the sole responsibility of the utility to provide the documentation of a compensable interest and NOT the Department's responsibility to seek it.
22.214.171.124 Utility Designation
The Project Manager and the Utility Coordinator will determine whether utility designation will be performed through MISS UTILITY, a Subsurface Utility Engineering (SUE) consultant or if utility designation is not required. The Project Manager specifies the Federal Highway Administration (FHWA) quality level of the SUE process required for the design of the project. If test holes are required, the Project Manager also specifies the number of test holes needed. The FHWA quality levels are classified as follows:
The American Society of Civil Engineers Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data CI/ASCE 38-02 shall be followed for the classification and depiction of subsurface utility data.
The results of the designation shall be forwarded to the Project Manager for incorporation into the plans and cross sections. The Project Manager, in coordination with the Utility Coordinator, shall determine which conflicts cannot be avoided and discuss alternatives with the affected utility company. The utility companies shall identify potential problems that could affect the project schedule at this stage of the plan development.
126.96.36.199 Subsurface Utility Engineering (SUE) Consultant
A Utilities Section SUE consultant or SUE consultant subcontracting to an approved Design Consultant may be utilized to acquire utility facility information. In all cases, the SUE consultant shall provide all information obtained from the approved tasks to the Project Manager, the approved Design Consultant for the project, and the DelDOT Utilities Section Coordinator. The SUE tasks may include utility designation, test holes, and coordination services. The SUE information includes, but is not limited to plans, test hole results, and review meetings.
The utilities are required to provide or verify the designation information on their facilities regardless of the Department's use of a SUE consultant.
4.1.2 Survey Plans
The Project Manager will provide two sets of survey plans per utility to the Utility Coordinator for distribution to each utility company. The utility will identify its existing and known abandoned facilities on the plans, indicating whether they are aerial, surface, or buried underground. The utility will also include information indicating
The utility company must return the information to the Utilities Section within 30 days of receipt unless a later date is agreed upon by the Project Manager and the utility representatives.
4.1.3 Preliminary Plans
188.8.131.52 The Project Manager shall prepare preliminary plans showing the proposed alignment, typical sections, profile, schematic drainage alignment, existing right-of-way, proposed right-of-way, easements, clear zone, test hole data on cross-sections (if obtained), existing utility facilities from the survey data, and other details. The American Society of Civil Engineers Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data CI/ASCE 38-02 standards shall be followed for the classification and depiction of subsurface utility data.
184.108.40.206 The Project Manager will provide the Utilities Coordinator with two sets of preliminary plans to distribute to each utility involved in the project. If current, the utility information on the previously marked Survey plans will be shown on the preliminary plans.
220.127.116.11 The utility company is required to mark the preliminary plans with any additional right-of-way necessary for relocation of facilities. The following is typically requested with the marked Preliminary Plans:
18.104.22.168.1 suggested design modifications that would eliminate relocations,
22.214.171.124.2 description of utility relocations along with estimated timeframe for construction,
126.96.36.199.3 list of stations and offsets where test holes are needed,
188.8.131.52.4 identification of any permits that may be required, and
184.108.40.206.5 information on any other utility's facilities located on its poles.
220.127.116.11.6 Joint Use or third party installation requirements.
18.104.22.168 A utility may be dependent upon another utility's plans and actions in order to complete the work. The Utility Coordinator should be made aware of this condition in order to ensure efficient coordination of the project.
22.214.171.124 The utility company owning the pole, duct system, etc is responsible for coordinating the relocation of any renters or lessees as required by the Telecommunication Act of 1996.
The utility company shall return the proposed work plan on one set of plans provided by the Department within 30 days of receipt. If a site meeting is held, the plans will be returned within two weeks of the meeting. In either case, a later date may be agreed upon by the project manager and the utility representatives.
126.96.36.199 Coordination & Site Meeting
If a subsequent site meeting is held, the utilities shall return preliminary plans at the meeting or within two weeks of the meeting. The Utilities Section will forward a copy of the plans to the Project Manager.
The Project Manager, in coordination with the Utility Coordinator and the utility company's representative, will review the preliminary plans for potential conflicts with existing utilities, and will determine which conflicts cannot be avoided. Any proposed signage or street lighting to be done in conjunction with the project shall also be reviewed and coordinated. If power lines must be relocated, the Project Manager shall coordinate the lighting needs, street lighting, signalization, traffic coordination installations, Traffic Impact Study (TIS) recommendations, etc. with the power company. DelDOT should apply for any necessary electric service from the utilities at this stage. If feasible, the utility poles may serve as light standards as well as carry the lines. Joint use agreements and location of DelDOT facilities shall be clarified as well.
188.8.131.52 Reimbursable Work
If reimbursable work is involved and the letter agreement has been executed, the utility shall provide a cost estimate for the preliminary engineering (PE). The Utilities Engineer may elect to waive a detailed cost estimate for Preliminary Engineering.
The Utilities Engineer shall grant a notice to proceed for preliminary engineering upon Departmental authorization of funding. A notice to proceed must be issued before the utility begins preliminary engineering in order for the preliminary engineering costs to be considered reimbursable by the Department.
Within 30 days of the issuance of the notice to proceed and receipt of preliminary plans, or the date agreed to by the Utilities Engineer, the utility company shall supply a Utility Plans, Specifications and Estimate (Utility PS&E) package, consisting of plans, specifications, and estimate and four sets of marked color-coded plans. Utilities may submit color-coded plans electronically, however they must be printable on standard size paper. These plans indicate:
1. existing to remain,
2. existing to remove,
3. proposed reimbursable and
4. proposed non-reimbursable.
Refer to Section 4.3 for further details on plan preparation and reimbursable work.
The Utilities Engineer will review the Utility PS&E package and verify any proposed reimbursable work.
4.1.4 Semifinal Plans
The Project Manager will give the assigned Utility Coordinator two sets of semifinal plans to distribute to each utility involved in the project. Any unresolved conflicts with the proposed construction and the utility's proposed relocation scheme need to be resolved.
The proposed relocation plan will be shown on the semifinal plans with any corrections to existing facilities and submitted along with the utility company's proposed Utility Statement (Resume of proposed work).
The Utility Statement (Resume of proposed work), submitted by the utility company, shall contain:
1. a description of the existing facilities;
2. any proposed changes, adjustments, or relocations;
3. the location, of the changes using station count and offsets;
4. quantities of borrow Type C if necessary;
5. the proposed time schedule (in calendar days) for completing the alterations, adjustments, or relocations for each phase of the Project's Sequence of Construction/ Maintenance of Traffic Plan; and
6. Any other information that may impact the state's contractor.
The utility will return one set of semifinal plans with the changes marked, the proposed relocation plan, and their proposed Utility Statement to the Utilities Engineer within thirty (30) days of receipt unless a coordination meeting is requested. If a coordination meeting is scheduled, the plans should be returned within two weeks of the meeting. In either case, a later date may be agreed upon by the project manager and the utility representatives. The Utilities Engineer will verify any proposed reimbursable work.
The DelDOT Project Utility Statement is subsequently prepared from all of the Utility Statements submitted by each of the public utilities. The DelDOT Project Utility Statement includes construction phases in which the work will occur and may include a list of locations for open cutting of roads. The Utilities Engineer will forward the DelDOT Project Utility Statement to the Project Manager. The applicable proposed relocation plans will also be forwarded.
The DelDOT Project Manager shall generate a bar chart showing the road construction sequencing and how it coordinates with the utility relocation sequencing. The Utilities Engineer with the concurrence of the Project Manager and Regional Construction Engineer may waive the bar chart requirement for minor projects.
The Project Utility Statement shall be submitted with the bar chart to construction. The Project Manager shall include the utility costs in the project cost estimate and append a construction sequencing bar chart, which does not contain specific dates. The following note shall be placed on the bar chart:
"The information shown in the Contract Documents, including the Utility Statement and the Utility Schedule contained herein, concerning the location, type and size of existing and proposed utilities, their locations, and construction timing has been compiled by the preparer based on information furnished by each of the involved Utility Companies. It shall be the responsibility of the State's Contractor to verify all information and coordinate with the Utility Companies prior to and during construction, as specified in Section 105.09 of the Standard Specifications." Other general notes referencing contractor expectations to be included on the DelDOT Utility Statement are shown in Appendix H.
The Project Manager shall sign approval of the DelDOT Utility Statement and return it to the Utilities Engineer.
If necessary, a coordination meeting will be scheduled with affected utility companies to review the Utility Statements and sequencing bar chart. Utility companies shall modify their Utility Statements based upon the coordination meeting. Final Utility Statements from the utility companies are to be submitted to DelDOT within 30 days of the meeting so that a revised DelDOT Utility Statement can be prepared.
4.1.5 Final Plans
When the plans are completed and the project is advertised, one set of final plans will be forwarded to each utility involved in the project. The Construction Engineer shall issue the notice to proceed with the relocation of facilities at or following the Preconstruction meeting.
For reimbursable alterations, adjustments, or relocations, the Utilities Engineer shall notify the utility, Project Manager, and Construction Region when the proposed utility work has been authorized. The Utilities Engineer will also direct the utility to proceed with its alterations, adjustments, or alterations. See Section 4.3 for further details.
4.2 Non-reimbursable Work
Adjustments to utility facilities occupying highway right-of-way by Master Franchise are not eligible for reimbursement. Exceptions are discussed in Section 4.3. If the facilities have to be relocated due to the Department's project, the Department will provide right-of-way for relocation of the facilities. The relocation of the utility facilities will be at the sole expense of the utility.
4.3 Reimbursable Work
4.3.1 Utility Reimbursement on Highway Construction Projects
Section 143, Title 17, Delaware Code determines the policies governing expenses of utility adjustments, removals, and relocations. A copy of Section 143 is located in Appendix F. The most recent copy of the Delaware Code may be found at Online Delaware Code at http://www.delcode.state.de.us/.
Utilities are required to use the procedures established by FHWA for reimbursement. These are explained in the U.S. Department of Transportation Federal Highway Administration Program Guide for Relocation And Accommodation on Federal-Aid Highway Projects including amendments.
The State shall fund adjustments, alterations, or relocations caused by DelDOT reconstruction, construction, relocation, repair, or maintenance of a public highway in the following circumstances:
1. Governmental Facilities - The facilities are owned and/or operated by a public utility of a municipality or of any governmental body or political subdivision of the State.
Appendix B - Agreement 86U-04
Appendix B - Agreement 86U-05
Appendix B - Agreement 86U-06
Appendix B - Agreement 86U-07
2. Court of Chancery Decision - The facility is private but located on fee simple real estate owned by the utility, or on a documented easement granted by a third party to the utility.
Appendix B - Agreement 86U-04
Appendix B - Agreement 86U-05
Appendix B - Agreement 86U-06
If the utility is the owner of the right-of-way in fee-or if the facility is located legally on private property-and this property is acquired by the State for the reconstruction of a highway or structure, the State will assume liability for the cost of altering, adjusting, or relocating the existing facilities. The utility must provide documentation in the form of a copy of the record from the Recorder of Deeds. The utility may request "prior rights" rather than compensation by the Department before the Department extinguishes the existing easement. Documentation must be completed by DelDOT Real Estate personnel and subsequently submitted to the Recorder of Deeds in the county in which said facilities are located.
3. "Prior Rights" - The utility may have "prior rights". Prior rights exist when a utility is determined to have legally occupied a public right-of-way prior to the time such right-of-way was conveyed to or acquired by the Department. Please see Section 4.3.3 for further details.
4. "Second Move" - The Department requires a second alteration or relocation of the same nongovernmental public utility facility within ten years from the date of completion of the initial alteration or relocation.
Appendix B - Agreement 86U-38
5. Change in Plans - The Department alters its plan of construction before project completion, requiring a nongovernmental public utility to relocate its facility that has already been partially or fully relocated in connection with the project. The Department shall reimburse the public utility for the cost of altering or relocating in relation to the change in the Department plans. An approved Utility PS&E is required before a notice to proceed for this work can be issued.
Appendix B - Agreement 86U-38
6. Delay - The Department cancels or does not commence a highway construction, reconstruction, relocation, repair, or maintenance project within a period of two (2) years from the date of authorization to proceed with nongovernmental utility work.
Appendix B - Agreement 86U-38
7. Temporary Facilities - The Department requests a temporary alteration or relocation of the nongovernmental public utility facility. For example, if facilities need to be relocated temporarily for a bridge replacement and will need to be moved again when the construction project is complete.
Appendix B - Agreement 86U-38
The amount of reimbursement to be paid to a public utility in Section 184.108.40.206 is the entire cost of alteration or relocation minus any betterment of the altered or new facility and any salvage value derived from the old facility.
220.127.116.11 Discretionary Funding
Decisions to fund utility relocations and adjustments in the following circumstances are left to the discretion of the Secretary of Transportation. The Department may enter into an agreement with a nongovernmental public utility by reason of highway construction, reconstruction, relocation, repair, or maintenance project as follows:
8. Special Circumstances - The Department may enter into an agreement with a nongovernmental public utility to reimburse for up to 50% for alterations or relocation if the facility is located within a highway right-of-way or public right-of-way by grant or franchise. The alteration or relocation must be necessitated by special circumstances with written approval from the Secretary of the Department of Transportation. A copy of the written determination of the Secretary shall be forwarded to the Public Service Commission for filing with the public records of the Commission.
Appendix B - Agreement 86U-36
9. Unique Materials - The Department may enter into an agreement if the nongovernmental public utility construction specifications require the use and/or storage of unique materials or supplies in advance of the construction contract.
Appendix B - Agreement 86U-37

Appendix B - Agreement 86U-07
Betterment is defined as any upgrade to a facility being relocated, made solely for the benefit of and at the election of the utility and not attributable to highway construction as determined by the Utilities Engineer. The cost of a betterment or increased size in facilities is only reimbursable in accordance with FHWA regulations of facility increase due to public safety or as allowed by specific agreements enabled by Delaware law.
When seeking reimbursement with betterment involved, the utility shall submit two (2) Utility PS&E packages. The first detailed estimate with color-coded plans indicates relocation or adjustment in kind and the second shows the facility size increase or betterment. Right-of-way acquisition and salvage value shall be included where applicable on all estimates. Refer to Appendix C for details.
4.3.3 Prior Rights
Prior Rights, as mentioned above, exists when a utility's existing facilities have a compensable right to be located on DelDOT right-of-way. Prior Rights occur in the following circumstances:
1. The utility facility was constructed on private property through a recorded easement of record in the Recorder of Deeds office and the facility and its easement are encompassed by a DelDOT project.
2. The utility facility was relocated onto or remained in DelDOT right-of-way under a previous project and at the time, it was agreed that if it became necessary to relocate for a future transportation project, the cost would be borne by the project participants. (For proper documentation of this right, the utility must furnish a copy of the utility agreement stating the arrangement previously agreed to by DelDOT.)
In cases of Prior Rights, the Department must approve all documentation. A flowchart of the process is located in Appendix K.
Utilities normally do not have compensable interest or "Prior Rights" in subdivisions. The right-of-way in subdivisions belongs to the State upon recordation.
4.3.4 Reimbursable Work Process
During the process of plan review discussed in Section 4.1, reimbursable work may be discovered. If the utility and the Utilities Section agree that reimbursable work will be involved, then the following must occur:
4.3.5 Utility Adjustment Agreements
Utility alteration, adjustment, or relocation agreements are used where the Department will be responsible for the cost of the work. An executed agreement shall be in place before any work begins when State and/or federal funds are used to pay for all or part of eligible utility adjustments. Samples of these letter agreements can be found in Appendix B.
18.104.22.168 Agreement Requirements
Utility adjustment agreements must include:
Work incidental to utility relocations shall be performed by the utility with its own forces including a utility's open-end and/or continuing construction contractor, or by an approved utility contractor, unless such work is included in the Department's construction contract by separate agreement. When a utility obtains a contractor for the relocation work, the utility, federal and state regulations apply.
22.214.171.124 Preparation of Agreements
When it is determined that a utility is to be reimbursed by the Department for a utility adjustment, the Utilities Section will prepare a letter agreement. The agreements are based upon State law and Court of Chancery decisions authorizing reimbursement, the type of ownership of the utility, state and/or federal participation, and the process for design and installation. Appendix B provides samples of letter agreements used by the Department.
The Utilities Section will prepare the appropriate letter agreement for adjustment work. The agreement will include preliminary engineering that may be accomplished as part of the Department's project, either by the utility's own forces or by its contractor. The preliminary engineering is considered part of the Department's project because the existing locations and the proposed adjustments or relocations are incorporated in the Department's construction plans.
The proposed letter agreement is forwarded to the Department's Deputy Attorney General for review/signature and/or comments. Any changes made by the attorney are incorporated in the agreement. Four original letter agreements are forwarded to the utility for signature and seal affixation, and returned to the Utilities Engineer. The Chief Engineer or the Assistant Director of Engineering Support as designee provides signature approval with the final authorization provided by the Director of Technology and Support Services. The agreement is considered executed when the Department's seal is affixed.
The distribution of the executed agreement is as follows:
Executed agreements are a part of the Utility PS&E submissions. The approved estimate and color-coded plans of the work involved are attached and considered part of the agreement.
126.96.36.199 Utility Plan Preparation
The Project Manager will furnish the Utilities Engineer with construction plans and cross-sections for review. When reimbursable work is involved, the plans shall be used by the utility to estimate the scope of the utility work to be done. Reimbursable work is described in Section 188.8.131.52. The utility shall submit the preliminary engineering (PE) estimate for any engineering required to design the alteration, adjustments and/or relocation. The Department Utilities Engineer may elect to waive a detailed cost estimate for preliminary engineering. A sample of the engineering estimate is located in Appendix C.
Utilities are required to use the procedures established by FWHA for reimbursement. The procedures are explained in the U.S. DOT FHWA Program Guide for Utility Relocation And Accommodation on Federal-Aid Highway Projects including amendments and the Federal-Aid Policy Guide (FAPG) Code of Federal Regulations Title 23.
The PE estimate shall become part of the letter agreement mentioned above in Section 184.108.40.206. When the PE estimate is approved, a notice to proceed will be provided to the utility to begin the design for the adjustments and/or relocations. The utility shall prepare the Utility Plans, Specifications and Estimate (Utility PS&E) for the relocation or adjustment and forward them to the Utilities Engineer for review.
Once the Utility PS&E package is reviewed and approved, it is forwarded to DelDOT Finance for funding authorization and approval. The Utilities Section must issue a notice to proceed before the utility can begin construction work. Any work performed prior to notice to proceed shall be at the sole expense of the utility.
220.127.116.11 Employment of a Consultant for Utility PS&E
As mutually agreed to by the Department and utility, preliminary engineering activities associated with utility relocation work may be done by an engineering consultant selected by the utility, with the approval of the Department. A utility must submit a letter to the Utilities Engineer requesting authorization to obtain a consultant to provide preliminary engineering services for utility relocations. The request shall state the type of work the consultant is expected to perform during the utility relocation for the project-i.e., prepare utility plans, specifications, estimates; inspect materials; and supervise work. The request shall meet the provisions established by federal procurement regulations of the U.S. DOT FHWA, and the applicable regulations of the Program Guide for Utility Adjustments on Federal-Aid Highways. Federal funds may participate in the cost of such services performed under existing written continuing contracts when it is demonstrated that such work is performed regularly for the utility in its own work and that the costs are reasonable.
When a consultant is to prepare the Utility Plans, Specifications and Estimates, the utility must provide the DelDOT Utilities Engineer with preliminary plans, estimates, and a fee schedule from the consultant for performing the work. (The utility is required to review and approve the data before submitting it to the Utilities Engineer.) After Departmental review, the information may be forwarded to FHWA for concurrence.
When the estimate and other data are acceptable to the State (and to FHWA, if applicable) the utility is notified to prepare and submit to the Utilities Engineer the specifications, estimates, and a draft of the contract between the responsible consultant and the utility. The draft must stipulate the work to be done under the agreement and the method of payment for preparing the Utility PS&E package.
A consultant fee that is based on a percentage of the work to be performed will not be approved.
When federal participation is involved in a highway construction project, the agreement with the consultant shall conform to federal procurement regulations and appropriate U.S. DOT regulations. Upon approval of the draft, the State may authorize the utility to execute the agreement with the consultant.
18.104.22.168 Processing Utility PS&E Packages
The Utility Plans, Specifications and Estimates (Utility PS&E) submitted by the utility shall include:
22.214.171.124.2 Four complete Utility PS&E packages shall be forwarded to the Utilities Engineer. The utility may in submit the color-coded Utility PS&E package electronically if in an acceptable format. Upon review and approval of the package for completeness and accuracy by the Utilities Engineer, the Utilities Section requests funding authorization and notifies the Project Manager. One copy of the Utility PS&E package is forwarded to the Construction Region for their use in concurring that the work is done in accordance with the Utility PS&E. See Section 4.4.4 for information regarding inspections.
4.4 Construction Coordination
4.4.1 Authorization Of Utility Work
The Utilities Engineer will notify the utility, Project Manager and Construction Region when the proposed utility work has been authorized. The Construction District directs the utility to proceed with its alterations, adjustments, or relocations.
When State or federal funds will pay all or part of the costs of adjustments, all work done by the utility's own forces shall be on a force account basis.
When a utility's request to perform the work by competitive bid has been approved, the following steps shall be taken:
When a utility requests permission to perform the work with a current continuing contract, using an outside contractor, the following shall take place:
4.4.2 Coordination During Construction
126.96.36.199 Utility Preconstruction Conferences
Representatives of each utility having facilities within the project limits, along with representatives of the contractor, may be required to meet with the Construction Region Engineer's representative to discuss in detail the effect that each utility's adjustment or relocation will have on the progress of the project.
188.8.131.52 Preconstruction Conferences
The Construction Region Engineer will notify the appropriate utilities, the "Miss Utility" Center, and the "Miss Utility" Representative, as to the place, time, and date that a preconstruction conference will be held.
184.108.40.206 Contractor's Schedule
The utility work on Department projects most often occurs simultaneously with the contractor's work and thus requires coordination. When this coordination is via a project utility meeting, a utility representative is required to attend. The utility and the contractor shall cooperate in scheduling work so that neither one is delayed by the other's operations. In addition, all traffic control for utility work must be performed according to DelDOT's Traffic Control Manual (Traffic Controls for Streets and Highways Construction, Maintenance, and Utility Operations) and coordinated with the immediate DelDOT project supervisor. This will be done to avoid conflicts and unnecessary disruptions in traffic flows through construction projects.
The utility is required to attend progress meetings called by the Construction Region Engineer or a designated representative to review progress on certain projects.
This section refers to changes required to the plans or estimates after the notice to proceed is given. Occasionally, field conditions necessitate revision to a utility's approved plan of adjustment or relocation.
220.127.116.11 Revision to Construction Project
Changes to Construction Projects and their impact on utility relocation costs shall be carefully considered before proceeding. Refer to the Section 18.104.22.168 summary of reimbursement to public utilities for "Second Moves" and "Change in Plans." The time involved, material availability, additional labor and utility costs shall be evaluated before changes are pursued.
The Utilities Engineer, Construction Engineer, and the Project Manager shall review any project plan revisions. Their approval is necessary in order to proceed with the revision.
22.214.171.124 Revision of Utility Plans and Estimates
The utility shall forward a copy of the revised plan and/or estimate and the justification for the change for approval by the Utilities Engineer. Upon approval of the change, the Utilities Section shall request additional funds to cover the added cost.

Clear Roadside Policy: The Department's policy of providing a clear recovery area (clear zone so as to increase safety, improve traffic operations, and enhance the aesthetic quality of highways by designing, constructing, and maintaining highway roadsides as wide, flat, and with no abrupt changes in slope as practical and as free as practical from natural or manufactured hazards such as trees, drainage structures, non-yielding sign supports, highway lighting supports, utility poles, and other ground-mounted structures. The policy addresses the removal of roadside obstacles that are likely to be associated with accident or injury to highway users. However, when such obstacles are essential, the policy provides for appropriate countermeasures to reduce hazards. Countermeasures include placing utility facilities at locations that shield the hazard from out-of-control vehicles by using breakaway features, impact attenuation devices, or shielding. Full consideration is to be given to sound engineering principles and economic factors in all cases. See the DelDOT Road Design Manual and the AASHTO Roadside Design Guide for more details.
Clear Zone: The total roadside border area, starting at the edge of the traveled way, available for safe use by errant vehicles. This area may consist of a shoulder, a recoverable slope, a non-recoverable slope, and/or a clear run-out area clear of fixed or non-traversable objects. The purpose is to provide errant vehicles a reasonable opportunity to stop safely or otherwise regain control of the vehicle. The desired width is dependent upon the traffic volumes and speeds, and on the roadside geometry. See the DelDOT Road Design Manual and the AASHTO Roadside Design Guide for calculation of Clear Zone widths.
