Windsor Woods, Princess Anne Plaza (including Northgate) and The Lakes Stormwater

​​​​​​​

Overview


 
Windsor Woods, Princess Anne Plaza and The Lakes are neighborhoods located ​​in what was once​​​ the undeveloped headwaters of the Lynnhaven River. According to aerial photos from 1949, the area was originall​y forest surrounded by farmland.  Much of the area has relatively low elevations.  This coupled with increasing sea levels (approximately 1-foot over the last 50 years) and the increasing frequency of storms with significant tides and rainfall amounts, has resulted in severe flooding of the neighborhood during these storm events.  The City has funded and completed a number of drainage improvement projects over the years (see the section “Past Drainage Improvement Projects”); a number of drainage improvement projects are currently underway or will be starting soon (see the section “Current Drainage Improvement Projects”); and, beginning with the FY18 budget, the City Council has established initial funding to develop a multi-year program of projects to comprehensively address flooding in Windsor Woods, Princess Anne Plaza and The Lakes.​​

Past Drainage Improvement Projects​

      • ​​Canal Number 2 Improvements, CIP 2-909:  The City cost-participated with the Army Corp of Engineers to construct Canal #2.  The canal extends from London Bridge to West Neck Creek.  The canal helps to alleviate flooding in and around Princess Anne Plaza and surrounding areas by diverting the stormwater runoff from London Bridge Creek to the Eastern Branch of the Lynnhaven River.  The project was completed in 1990, and the total project cost was $55M.
      • Rosemont Road – Windsor Woods Drainage, CIP 7-115:  This project included the construction of two stormwater detention ponds; one on the Bow Creek Golf Course and another one along Rosemont Road adjacent to the St. Francis Episcopal Church.  It was completed in May 1996, and the total project cost was $1.2M.
      • Princess Anne Plaza Drainage Phase 2, CIP 7-114:  The first phase of this project included channel improvements and channel re-routing within Bow Creek Golf Course.  It was completed in August 1996.  The second phase included box culverts under Club House Road and Bow Creek Boulevard. It was completed in June 1998.  The third phase included channel improvements from Bow Creek Boulevard to Rosemont Road and a pedestrian bridge in Northgate Park. This was completed in October 2000.  The total project cost was $4.3M.
      • Stormwater Infrastructure Rehabilitation, CIP 7-004:  This project provided inspection and rehabilitation of stormwater infrastructure.  The stormwater piping system was mapped, cleaned, and repairs were made by either slip-lining pipes or pipe replacement.  This was completed in 2008, and the total project cost was $5M.  
      • Bow Creek Rec Center Storm Drainage Work, CIP 3-405:  Storm drain improvements were installed with the Bow Creek Recreation Center to help drainage for the recreation center as well as provide additional storm drainage improvements for Club House Road and the immediate area.  This was completed in 2015, and the total project cost was $600K.

​​Current Drainage Improvement Projects

      • ​​Windsor Woods Canal, CIP 7-028.002:  This project will dredge the 4,100-ft canal to its original capacity.  The approximate volume of dredge material to be removed is 10,900 cubic yards.  Construction Notice to Proceed was given June 27, 2017 and will be complete in July 2018.  The total project cost is $2M.
      • Windsor Oaks West – Phase I CIP 7-415:  This project dredged the 1,510-ft canal to its original capacity.  The approximate volume of dredge material removed wa​s 4,218 cubic yards.  Construction is complete.  The total project cost was $700K.
      • Windsor Oaks West – Phase II CIP 7-415:  This project dredged the 2,760-ft canal to its original capacity.  The approximate volume of dredge material removed was 7,053 cubic yards.  Mobilization and dredging began in July 2017 and was completed in January 2018.  The total project cost was $675K​.
      • Windsor Oaks West – Phase III CIP 7-415:  This project will dredge the 2,150-ft canal to its original capacity.  The approximate volume of dredge material to be removed is 3,000 cubic yards.  Construction will begin in October 2018 and be complete in July​ 2019.  The total project cost is $625K.
      • Princess Anne Plaza – Northgate Ditch, CIP 7-028.001:  This project will dredge the 6,000-ft canal to its original capacity.  The approximate volume of dredge material to be removed is 3,000 cubic yards.  Construction Notice to Proceed was given May 19, 2017 and will be complete in July​​ 2018.  The total project cost is $2M.​​​​​​

Current Update

Michael Baker International, teamed with CDM Smith, was chosen to provide technical engineering services to develop and apply stormwater management models, analyze existing stormwater management infrastructure, identify and recommend improvements including cost and phasing plans, design, preparation of construction documents, and construction phase services, for Windsor Woods, Princess Anne Plaza and The Lakes Combined Drainage Improvements.  An detailed engineering analysis to develop the specific program of flood control measures is underway.  The analysis will identify the needed improvements, the costs of those improvements, the implementation plan of the improvements including a phasing plan and the environmental permits that may be required to construct the improvements. 

April 6, 2018

Recently, two modeling studies to evaluate preliminary alternatives to alleviate flooding in the three neighborhoods were developed by the City's consultant, CDM Smith.  Links to these studies are available in the "Plans and Studies" area of this web page.​
