Project Details Towlston Meadows Sec 3 Pond 1 Capital Facilities/Utilities Design and Construction Division/Transportation Stormwater Construction Branch Description: The purpose of Towlston Meadows Pond retrofit project was to increase the quality of the water discharge from the pond without creating any adverse impact to the existing downstream outfall system. In addition, enhancements were made by creating a new access road to better access the facility for any future maintenance needs. This project was substantially completed on-time and within budget, on April 4, 2014. Project Overview: • Re-grading of the pond and installation of four (4) 18-inch deep micro pools. • Increase storage volume by approximately 50% and provide water quality benefits to include removal of 3.4 lbs./yr. total phosphorus, 15.4 lbs./yr. total nitrogen, and 662 lbs./yr. total suspended solids. • Construct an all-weather maintenance access road using tufftrack pavers technology. • Incorporate native vegetation to promote the natural landscaping restoration of the project site.
