WLC was hired to provide design and contract administration services for the Glendale Avenue: 21st Street to 24th Street Storm Water Improvements and the Eastdale Creek Storm Water Detention Facilities. Recommendations included in the City of Casper’s 1983 Storm Water Management Master Plan, which WLC developed, were to construct a storm water detention facility near the intersection of Glendale Avenue and 24th Street and increase the size of the storm sewer system within Glendale Avenue. The Glendale Improvements included upsizing existing storm sewer and increasing inlets along Glendale Avenue and intersecting streets. This also included the installation of new sanitary sewer in some areas and rehabilitating existing sanitary sewer in other areas. The project also consisted of replacement of existing water mains, reconstruction of roadway, and geotechnical engineering. The Eastdale Creek Storm Water Detention Facilities project included geotechnical engineering design and construction of two earthen dams to detain storm runoff. This included analyzing future runoff within the Eastdale watershed using CUHP procedures. At full capacity, the structures detain approximately 80 acre-feet of water and will detain the runoff produced by the 100-year storm event. The release of water from the structures is effectively metered by several outlet structures to reduce the rate of runoff entering the Glendale Avenue underground storm sewer. These detention structures are dry the majority of the time and hold water as needed during large storm events.
