Ashville Park Stormwater

​​​​​​Overview

The Ashville Park neighborhood is located in the southeastern part of the City bounded by Princess Anne Road to the west and Sandbridge Road to the east.  The Stormwater drainage system drains through 15 on-site interconnected lakes to Ashville Creek and then to Muddy Creek and ultimately into Back Bay.  During intense rainfall events or windblown tidal events that are accompanied with moderate rain events, Ashville Park experiences wide-spread roadway flooding.  During three severe rainfall events in 2016 (Tropical Storm Hermine Sept. 1, 2016; Tropical Storm Julia Sept. 19, 2016; Hurricane Matthew Oct. 2016), in addition to roadway flooding, residential structural flooding was experienced.      The City retained a national engineering firm to develop a comprehensive drainage analysis to ide​ntify improvements to address the flooding.  This analysis is complete and the FY18 capital improvement program recently adopted by the City Council provides funding to begin to implement the initial improvements.  Refer to the “Related Documents” section to read the “Ashville Park Stormwater Management System Flood Mitigation Plan, February 21, 2017”.

Current Drainage Improvement Projects

      • ​​​Ashville Park Drainage Improvements, CIP 7-047:  This is a multi-phase project that will alleviate roadway and structural flooding by utilizing pump stations, storm drain pipe improvements in the existing villages, interconnections between the lakes, and a new channel from the lakes to the downstream drainage ditch.​ 
      • Ashville Park Weir, CIP 7-416 (SW Infrastructure Rehabilitation & Improvements II):  This project will provide for the construction of a permanent weir structure at the outfall ditch at Flanagans Lane to protect against tidal influence on the Ashville Park storm drainage system.

​​​​Current Update

Until sufficient flood control improvements have been designed and constructed, Public Works Operations will be utilizing portable pumps to lower the lake levels in advance of significant storm events, to help mitigate flooding.  Public Works Engineering has issued a work order for the preliminary design of the initial flood control improvements currently funded in CIP 7-047.
