DelDOT Subdivision Manual Changes

On Tuesday, March 16th, ACEC-Kent County met with Marc Cote of DelDOT to discuss some of the recent changes to the Subdivision Manual. Melissa Koenig, P.E., Associate of Landmark/JCM attended the meeting. The following were some of the changes that were discussed:

• Soon, there will be a GIS application available online.

• When calculating site distance, please use the JMT spreadsheet. When showing the site triangles on a plan, the decision point is 18’ from the edge of travel lane (can range from 14.5’ to 18’, but for the most part use the 18’). The spreadsheet can be found under the subdivision section at http://deldot.gov/information/business/

• The Subdivision Plan Review Schedules online are for Record Plans and Construction Plans. The engineer can attend the Plan Review Meeting if it will be helpful. The schedule for offsite improvements has not been determined yet. The plan review schedule is available online at http://deldot.gov/public.ejs?command=PublicPlanReviewSchedule

• Please note on the Site Plan Gate-Keeping Checklist one of the required items is a photo showing the proposed entrance staked. You will also need to provide calculations showing the minimum connectivity ratio of 1.4 is met. Marc said this will be covered in future training sessions by DelDOT. The Gate-Keeping checklist is available online at http://deldot.gov/information/business/subdivisions/Subdivision_Gatekeeping_Checklist.pdf

• The DelDOT ES2M Checklist should be completed for onsite and offsite submittals. (http://www.deldot.gov/information/pubs_forms/manuals/es2m/index.shtml)

• If the total open area of culvert pipes is > 20 S.F., then it is considered a bridge (see Appendix Q). If there are multiple pipes, all the areas must be added together.

• The Pre-Submittal Meeting (required for ADT>200) can be before or after the PLUS process. (http://deldot.gov/information/business/subdivisions/Subdivisions_Pre-submittal_Meeting_Requirements.pdf)

• Please submit the meeting request form when asking to meet with the subdivision section so that they can be prepared for the meeting. The request form can be found under the subdivision section at http://deldot.gov/information/business/
