Project Description: Riverwalk Residential Subdivision Design and Development
Owner:
Location: Wells, Maine
Project Team: Walsh Engineering Associates, Inc.
Work Scope:
WEA provided engineering services for the development of a 33-lot residential subdivision in Wells, Maine, located in a sensitive fishery adjacent to the banks of the Merriland River and Hobbs Brook. WEA analyzed the hydrology and hydraulics of the site, breaking it down into 24 sub-watersheds and 14 stormwater treatment BMPs, including buffers and soil filters. As well as the on-site analysis, WEA studied the hydrologic impact of the 9,000-acre upstream watershed for the sizing of the four stream crossings including a bridge structure. The project required approval by the Maine DEP under SLODA and therefore required an analysis that met the Chapter 500 stormwater rules for flooding and treatment. Permitting included local (Town of Wells), state (Maine DEP SLODA, NRPA Tier II NRPA, Maine IF&W), and federal (Army Corps of Engineers). Given the issues related to the fisheries, the analysis was rigorously reviewed and subsequently received approval.
