Project Summary

Timmons Group is providing stormwater-related engineering and consulting services including permitting, planning and design for the City. The City currently operates under a National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit. We are working with the City to identify discrete task order projects to assist with the planning, development, and execution of its Stormwater Management Program to meet the applicable requirements of the MS4 Permit, the VSMP regulations, and the City’s adopted Capital Improvements Program.

Services consist of providing assistance in implementing program  lements within the current permit, as well as providing technical support in drafting and submission of annual reports and permit updates as required by Virginia DEQ. Services include, but are not limited to:

  • Preparation of a Chesapeake Bay TMDL Action Plan (Action Plan) that will cover the City’s regulated MS4. The Action Plan will assist with meeting the Special Condition for the Chesapeake Bay TMDL (Section I. C) in the City’s MS4 Permit
  • Performing dry weather screening of up to 50 stormwater outfalls to implement the City’s Illicit Discharge Detection Program
  • Developing written procedures for good housekeeping on City-owned/operated facilities
  • Presentation with the City’s Engineering Division to include other City Departments/ Divisions that share responsibility for implementation of the MS4 Permit Program Plan to discuss permit requirements, responsibilities by Department/Division, and summarize the importance of compliance
