URBAN STREAM RESTORATION FOR CENTRAL CREEK SPECIFICATIONS

PART 1 PROJECT DESCRIPTION

1.01 The project is a stream restoration and revitalization project to enhance, restore, and stabilize two sections of a 4,800 LF reach of Central Creek by removing concrete channel liners, restoring in-stream habitat, and restoring/enhancing riparian buffers, directly addressing a source of impairment. Segments of the restored riparian corridor will include a walkway that will establish a greenway trail connection to local businesses and the downtown area; portions of the greenway trail that do not follow the Central Creek riparian corridor will use existing and/or proposed sidewalks to connect the riparian segments of the greenway trail. It is an American Rescue Plan Act (ARPA) American Rescue Plan (ARP) Resource Protection Grant funded project.
