Markham Ravine Corridor Enhancement

Lincoln, California

Foothill Associates worked on a 200┬▒ acre project with the City of Lincoln within the Markham Ravine corridor to restore and enhance wildlife habitat values, improve the aesthetic appearance of the corridor, enhance flood protection and management, and create an open space system that is a regional recreational destination. The project involved the development of an overall concept plan, master plan, and the preparation of construction documents for Phase 1. Improvements within the corridor included a Class I trail system, interpretive signage, a nature interpretive center, pedestrian bridge crossings, picnic areas, and parking/staging areas. New overflow channels and wetland basins will increase storm water management options and habitat diversity within the corridor. Design considerations were carefully coordinated and managed to minimize or eliminate the need for Federal permits and to comply with the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA).

 

Foothill Associates facilitated all of the environmental permitting and drafted the Adaptive Management Plan for the area. The Initial Study and Mitigated Negative Declaration (IS/MND) included an analysis and discussion of potential impacts related to aesthetic, air quality, biological resources, cultural resources, geology and soils, hydrology band water quality, hazards and hazardous materials, land use, noise, and transportation. Foothill Associates staff conducted all resource assessment and jurisdictional delineation work.  Mitigation measures were identified to reduce all potentially significant impacts to less than significant levels. The final IS/MND and Mitigation Monitoring and Reporting Program (MMRP) were adopted by the City.

 

This project included numerous public presentations to community groups, the City Parks and Recreation Committee, and City Council.
