Recommendation
Staff recommends that the Mayor and Council award and authorize the City Manager to Execute a Contract Responsive to Invitation for Bid (IFB) #25-25, Croydon Creek & Calvin Park Tributary Stream Restoration Project, to Kinsley Construction, LLC, of York, PA in the amount not to exceed $4,640,979.75.
Discussion
IFB #25-25, Croydon Creek & Calvin Park Tributary Stream Restoration, is a publicly bid, stream restoration project, within Civic Center Park, near the Croydon Creek Nature Center of Rockville, MD. This project restores the streams at Croydon Creek and the Calvin Park Tributary to Rock Creek. These streams have highly eroded stream banks that are significant sources of sediment that reduce water quality within the watershed and ultimately the Chesapeake Bay. This project also constructs a park access path enhancement.
The Croydon Creek & Calvin Park Tributary Stream Restoration project (The Project) is located within the Rock Creek Watershed. Rock Creek originates in northern Montgomery County, passes briefly through Rockville, and continues through the District of Columbia to meet the Potomac River. The Rock Creek watershed encompasses four (4) square miles of the eastern side of the City. The watershed includes parts of Rockville Town Center and the Rockville Pike/Hungerford Drive corridors, the neighborhoods of Lincoln Park, East Rockville and Twinbrook, and industrial areas along Gude Drive and Southlawn Lane, as well as Redgate Park and Civic Center Park.
The Project is within a park solely owned by the City of Rockville. This project includes two separate stream segments. Between the segments is a stream section previously restored by the Washington Sanitary Sewer Commission. The Croydon Creek Stream segment begins at a failed dam northwest of the Glenview Mansion and continues easterly to Rock Creek Regional Park. The Calvin Park Tributary segment begins at Baltimore Road and flows in a northerly direction to Croydon Creek. Both stream segments are in poor condition, are highly eroded, over-widened, and are poorly graded. Excessive erosion over time has resulted in sediment accumulation throughout the proposed project area as well as sediment transport downstream.
The Croydon Creek & Calvin Park Stream Restoration project is designed to improve water quality and restore habitat both in stream and within the forested buffer. The proposed design includes natural channel design techniques, such as rock weirs and riffle grade control structures, to provide lifting of the channel to reconnect to the floodplain during storm flows and to enhance in-stream habitat. Additionally, a new pedestrian bridge crossing is included to cross an outfall channel originating at Norbeck Road, along the Heritage Trail.
Mayor and Council History
The Mayor and Council authorized the City Manager to sign a memorandum of agreement with the U.S. Army Corps of Engineers and the Maryland Historical Trust to allow the City of Rockville to remove a historic dam in Croydon Creek as part of the stream restoration project on November 7, 2022.
Additionally, the Mayor and Council authorized the City Manager to sign a grant agreement with the Maryland Department of Natural Resources (DNR) in the amount of $2,000,000 to partially fund the cost of the stream restoration project on January 9, 2023.
