DelDOT Land Development Reviews

JMT provided reviews of record (site) plan submissions, subdivision street plans, entrance plans, and offsite improvements for compliance with DelDOT and AASHTO standards.


Kent and New Castle Counties, DE


Delaware Department of Transportation

As a result of the rapid development occurring in the State of Delaware and a growing backlog of major subdivision and commercial entrance applications, the Delaware Department of Transportation (DelDOT) asked JMT to assist with the reviews of these projects in Kent County. In order to make the approval process more efficient, JMT was given the authority to approve applications on behalf of DelDOT. Using a team of reviewers, JMT reduced the backlog within several months, from starting the reviews to responding to plan submissions with comment letters in a timely manner.

Also as a result of the rapid development throughout the state, DelDOT experienced a growing backlog of stormwater reviews associated with frontage road and other roadway improvements within DelDOT’s right-of-way, as required for the development projects.

Using a team of reviewers, JMT began reviewing stormwater management, erosion and sediment control, and drainage design for projects throughout the entire state. JMT worked as an extension of staff for DelDOT’s Stormwater Engineer, including attending meetings with engineers, Delaware Department of Natural Resources and Environmental Control, and other delegated agencies. JMT also provided training to DelDOT staff to increase their technical knowledge of drainage design.

In addition to the reviews, duties included meeting regularly with engineers and developers regarding applications, traffic impact study recommendations and required off-site improvements, preparing letter agreements between DelDOT and applicants, and issuing comments on behalf of DelDOT for the Regional Planning Commission (RPC) and Preliminary Land Use Service (PLUS).

To streamline and standardize the review process, JMT created checklists and standard comments for its reviewers to use for record plan, subdivision construction, and entrance plan reviews, which DelDOT added to its revised Standards and Regulations for Subdivision Streets and State Highway Access manual.

JMT helped facilitate drainage reviews by creating the pipe cover/pipe angle chart for the developer’s engineers to complete and submit for review to verify stormdrains placed under subdivision streets and at their junction with drainage structures adhered to DelDOT’s Standard Construction Details.

Due to the increasing number of applications and offsite improvements, JMT created a web-based tracking and documentation system to facilitate the creation and management of project reviews, offsite improvements required by applicants, and project-related data. The database allows the reviewer to complete the checklists online, select the standard comments, and output a formatted comment letter to send to the developer’s engineer or query reports, determining the number of applications approved within a defined time period or the number of developers participating in an offsite improvement. The web-based interface provides maximum accessibility by multiple consultants, DelDOT staff and JMT staff.
