Explanation
§ Pond projects are implemented in accordance with the City Council-approved Pond and Dam Rehabilitation Policy, aimed at protecting as many existing ponds as possible prior to removal by private development or structural failure, and to use these ponds as a highly cost-effective tool to achieve water quality and flood control goals, and permit compliance.
§ On average, improving existing ponds costs one-fifth the expense of creating new water quality measures providing equivalent environmental benefit.
§ The Marlwood-Waverly Water Quality Enhancement Project is located in Council District 5 encompassing two ponds and a drainage culvert.
§ The 5.9 acre Marlwood pond and 17.9 acre Waverly pond are located east of the intersection of East W.T. Harris Boulevard and Albemarle Road. The ponds are located in the McAlpine Creek watershed and improve polluted runoff from approximately 1,348 acres of developed land.
§ This project will also replace the drainage culvert under Marlwood Circle, which is structurally deficient and contributing to failure of the existing pavement.
§ The project will include the following types of work:
- Erosion control,
- Storm drainage,
- Rebuilding the failing dam and spillway systems, and
- Seeding and site restoration.
§ These enhancements will improve the quality of water moving through the ponds before the water discharges into the creek by allowing pollutants to settle out and remain in the sediment at the bottom of the pond.
§ On December 22, 2017, the City issued an Invitation to Bid; three bids were received from interested service providers.
§ United Construction Company Inc was selected as the lowest responsive, responsible bidder.
§ The project is anticipated to be complete by first quarter 2020.
