Site work for a water / sewer project in Silver Spring, Maryland. Conceptual plans call for site work for a water / sewer project.

The original plans approved in 2017 by the Washington Suburban Sanitary Commission (WSSC) for Elizabeth Square included the replacement of the 10-inch sewer line on the west portion of the WMATA and CSX tracks with a 12-inch line that did not go under the tracks. The current proposed Purple Line development design approved by WSSC includes an alternate sewer line routed under the tracks. WSSC now requires HOC, in coordination with Purple Line Plan (PLP), to install an upsize 15-inch sewer line along the alternative route to meet the capacity of both Elizabeth Square and the proposed HOC Headquarters building at Fenwick Lane andSecond Avenue. WSSC requires the revised plans to be in effect before the Elizabeth House III and the South County Regional Recreation and Aquatic Center (SCRRAC) building can obtain an occupancy permit. The current approved contract documents indicate that the new Capital Crescent Trail (located in between Elizabeth House and CSX/Washington Metropolitan Area Transit Authority (WMATA) tracks), including the associated retaining wall, trail and storm systems will be completed by the Maryland Transportation Authority (MTA)/Purple Line. The HOC project will eventually connectinto these Capital Crescent Trail storm systems in order to achieve final inspections. However, MTA/Purple Line is not scheduled to install these Capital Crescent Trail storm systems until after the HOC project completion date. As a result, HOC must install a temporary 15-inch storm line to accommodate the Elizabeth House III and South County Regional Recreation and Aquatic Center (SCRRAC) project until MTA/Purple Line is completed. The project is included in the county's 2023-2028 Capital Improvement Program (CIP). As of July 29, 2022, further details regarding design and construction have not been identified.* *Project information has been obtained through a public capital improvement plan (CIP).
