Project Description
E&A provides annual Post-Construction Stormwater Management Plan (PCSMP) inspections for the Windgate Ranch residential subdivision, a 170-acre development with approximately 350 residential lots. Windgate Ranch—Sanitary Improvement District #557—is responsible for maintaining 20 stormwater treatment structures, including 14 bioretention basins, five rain gardens, and one dry detention basin. E&A was hired to conduct inspections and prepare reports in compliance with City of Omaha requirements. During development, temporary sediment basins were used to manage runoff from grading and construction activities; these were later converted into permanent post-construction features as the site stabilized with vegetation.
Note: As of July 1, 2008, the City of Omaha requires the installation of post-construction stormwater management features as part of new land development to comply with the requirements in their Municipal Separate Storm Sewer System (MS4) permit. Post-construction stormwater management applies to land development that results in an increase of impervious surface area greater than 5,000 square feet.
