Section 4.5 - OFF-SITE IMPROVEMENT PLAN SUBMITTAL REQUIREMENTS

Universal Citation: 2 DE Admin Code 4.5

Current through Register Vol. 28, No. 3, September 1, 2024

Prior to submittal of off-site improvement plans, the engineer shall schedule a pre-submittal meeting with DelDOT Development Coordination. It is recommended that this meeting should be held at least 12 months prior to the intended start of construction of the off-site improvements. The engineer shall complete and submit a design criteria form (http://devcoord.deldot.gov > Forms) prior to the meeting.

Any plan submitted to DelDOT for review must contain all elements listed in this section. When a plan is submitted for review, it will be checked to ensure the required elements are on the plan. If any elements are not relevant to the particular site then these elements shall be specified in the submittal letter. If all elements are not on the plan, the plan will be returned to the engineer for resubmission with no comments provided by DelDOT.

The developer's engineer shall prepare and submit all construction plans and right of way exhibits to DelDOT for review and approval for the project as outlined in the Off-site Improvement Agreement described in Chapter 2. All required submissions to internal DelDOT support sections shall be made to the Development Coordination Section and then shall be distributed throughout DelDOT in accordance with these regulations. The engineer shall design the project in accordance with the American Association of State Highway and Transportation Officials (AASHTO) A Policy on Geometric Design of Highways and Streets, DelDOT's Road Design Manual (RDM), and DelDOT Standards Specifications, Policies, and Practices. In instances where the engineer determines that the project cannot comply with these standards, the engineer shall provide to DelDOT a completed design deviation form. DelDOT shall have the final authority on any process modifications or design deviations.

The engineer shall coordinate with the utility companies to determine existing facility locations and to start the discussions on possible relocations.

Existing deeds, plot plans, existing roadway plans and field surveys shall be used to establish and verify the existing right-of-way and property lines. The engineer or surveyor is responsible for attesting to the right-of-way shown on the plans.

The engineer will work through the Development Coordination Section for pavement evaluation and design verification. This may include pavement cores and subgrade soils analysis. The engineer will work through the Development Coordination Section for hazardous material/contaminated site delineation.

The engineer will work through the Development Coordination Section to identify environmental or cultural resources that are present within the existing and/or proposed right-of-way. The engineer shall prepare, apply for, and obtain all necessary permits and environmental or historic documentation required by federal, state, and local authorities. Copies of the permits and supporting documentation shall be provided to DelDOT prior to final plan approval.

DelDOT will provide assistance in identifying but not obtaining all necessary permits and coordination for off-site road improvements. To construct the off-site improvements, the project may require, but not be limited to:

A. Right-of-way

B. Utility coordination

C. Permits associated with the Environmental Protection Agency's (EPA) Clean Water Act, Section 404

D. Permits associated with the Federal Highway Administration's (FHWA) Department of Transportation act of 1966, Section 4(f) regarding historical sites

E. Permits associated with the Federal Highway Administration's (FHWA) Land and Water Conservation Fund Act, Section 6(f) regarding parklands

F. Permits associated with the National Pollutant Discharge Elimination System (NPDES) regarding erosion control

G. Delaware Department of Natural Resources and Environmental Control (DNREC) Wetlands and Subaqueous Land Permit

4.5.1 Off-Site Improvement Plan Submittal Requirements - Content and Process

A. Off-site Improvement Plans shall be prepared in accordance with Construction Plan standards as established in Section 4.3 and the requirements outlined in this section.

Submittal shall include the following items, along with the Off-site Improvement Gatekeeping Checklist and Design Checklist (http://devcoord.deldot.gov > Checklists):
1. Title sheet

2. Plan sheet index

3. Notes and legend sheet

4. Typical sections as defined in Section 4.3.3

5. Horizontal and vertical control points

6. Construction plan with proposed design (including conceptual drainage layout and clear zone)

7. Existing and proposed profile including existing and proposed drainage, underground utilities with test hole data, soil boring, and test holes plotted

8. Grades and Geometrics showing where coordinates are to be given (edge of gutter, begin/end of transitions, and critical curve points) for proposed geometrics and tick marks where grades will be given (edge of gutter in intersections, super-elevation transitions, and critical points)

9. Stormwater management plans and report or a waiver from the SWM Engineer

10. Site specific construction details. (A separate plan sheet may be required for details.) DelDOT standard details shall not be shown on plans.

11. Construction Phasing, M.O.T., and Erosion Control plans (with utility construction phasing taken into account)

12. Detour plans

13. Environmental Compliance Plan

14. Lighting plan, including proposed pole locations

15. Landscaping plan

16. Utility relocation plans, including overhead and underground utility relocations

17. Signing and striping and conduit plans

18. Signalization plans

19. Cross sections as defined in Section 4.3.10

Refer to DelDOT's Model Plans at: http://www.deldot.gov/information/business/drc/modelplans.shtml for a sample plan set.

B. DelDOT's Development Coordination Section will distribute the Construction Plans to the following stakeholders for review and comment:
1. Stormwater Engineer with Stormwater Report

2. Construction Management to review constructability and phasing

3. Traffic Section for review and comment pertaining to signal design, proposed signing and striping, and detour plan consideration

4. Roadside Development Administrator to determine tree replacement requirements and subsequent real estate needs, and to ensure proper selection of tree types for replacement policy. The engineer shall coordinate tree impact and mitigation analysis with a landscape architect.

5. Design Services Section for documentation of proposed impacts to environmental and cultural resources. Any permits that have been issued shall be made available to the Design Services Section. The engineer should also make Design Services aware of all correspondence that has occurred between the resource agencies and the developer.

6. Materials and Research

7. Chief Safety Officer

8. Bicycle/Pedestrian Coordinator

9. Architectural Accessibility Board (for approval)

10. DTC

11. Chief Engineer

12. Public Works

13. Others, as determined by the Subdivision Engineer

C. Depending on the complexity of the project, DelDOT may require the Developer to hold at least one Public Workshop. This workshop should be held soon after the initial plan submittal.

1. Symbols and legends

2. Right of way plan view

3. Right of way data

4. Right of way tabulation (see http://devcoord.deldot.gov > Checklists for the Right of Way Plan Checklist)
