The work covered by this specification consists of routine structural and vegetation maintenance for the City of Omaha’s (City) Rockbrook Creek Green Infrastructure (Rockbrook Creek GI) site located between Prairie Lane Park to approximately 115th Ave and Elm St. It was constructed as part of the City’s OPW 52101 Rockbrook Tributary Rehabilitation Project at Frederick Street in 2014. The Rockbrook Creek maintenance area is approximately 1,100 feet long, with a culvert under Frederick Street between 115th Avenue and Westwood Lane, adjacent to Prairie Lane Park. The project was constructed primarily in 2013. The channel has native grasses along the banks and clusters of shrubs along the fence line north of Frederick Street. There are granite boulder grade control structures along the channel to minimize erosion. The channel is enclosed in a chain link fence line, which as two gates for personnel access on the east side of the channel near Frederick Street. Refer to the attached drawing sheets for the location and site access locations.
