TITLE
Recommendation to authorize City Manager to execute an amendment to Agreement No. 30773 between the City of Long Beach and Moffatt & Nichol Engineers for engineering professional services for the Colorado Lagoon Restoration Project, in an amount not to exceed $79,293, and any amendments to the contract necessary to extend the term, amend the scope of work or adjust the fee schedule of hourly rates for inflation for any term extensions. (District 3)
DISCUSSION
The Colorado Lagoon (Lagoon) is a 28.3-acre tidal lagoon located in the middle of a suburban neighborhood (map attached). It serves three main functions: 1) hosting sensitive estuarine habitat; 2) providing public recreation (including swimming); and 3) retaining and conveying storm flows. Unfortunately, the water and sediment quality within the Lagoon has degraded over time. To improve the conditions of the Lagoon, a Master Restoration Plan has been developed and is being implemented in accordance with funding availability.
On June 10, 2008, the City Council authorized the City Manager to execute a contract with Moffatt & Nichol for engineering design services. The design development phase was split into three main parts. Part 1 of the engineering design effort covers those project components that are being funded by the State Water Resources Control Board with federal Stimulus funds. Part 2 covers dredging of contaminated sediments, contouring of the side slopes to improve intertidal and transitional-zone wetland habitat, and to revegetate the impact areas with native plants. Part 2 project components are being funded, in part, by the U.S. Army Corps of Engineers. Part 3 covers all other improvements that are not currently funded (e.g., removal of the North Arm restroom, parking lot and access road, revegetation, and walking trail installation). The Part 3 effort remains suspended until additional funding is identified. The engineering designs for Part 1 have been completed, and efforts are under...
