Hanover's staff worked to secure a California Department of Fish and Game Streambed Alteration Agreement, an Encroachment Permit with the Central Valley Flood Protection Board, and a concurrence determination from the USFWS verifying that the proposed project would not result in impacts to the Valley Elderberry Longhorn Beetle. The proposed bicycle path proposed for the southwestern quadrant of the City of Chico and will extend from an existing bike path undercrossing at Highway 99 and Humboldt Avenue over Little Chico Creek to the East 20th Street Community Park. The path would continue through the park and terminate at Chapman Elementary School.

Hanover's staff worked to secure permits including a Section 404 Nationwide 33 Permit from the Corps of Engineers, a Regional Water Quality Control Board clean water certification, California Department of Fish and Game Streambed Alteration Agreement and the Glenn County Resource Conservation District use permit. This project ultimately involved consultation with the National Oceanic and Atmospheric Administration, Fisheries and the U.S. Fish and Wildlife Service over potential impacts to endangered species. The project will remove gravel from streamside habitat and in turn will work with the RCD to remove non-native vegetation from the creek bed and will create wetlands to further restore essential fish habitat for endangered anadromous fish.

Hanover 's environmental compliance specialists created an extensive permit package for two oil recycling facilities. These permit applications which are required by the Department of Toxic Substance Control (DTSC) contain operation plans, safety and contingency plans, community profiles, inspection plans, descriptions of waste streams and waste management plans.

Kamie Loeser, Hanover's Senior Planner, prepared and filed the Clean Water Act (CWA) Section 404 Nationwide Permit 14-Linear Transportation Project for a 2-mile stretch of roadway in El Dorado County . The improvement and expansion of the proposed roadway was part of the implementation of a capital improvement program associated with a Specific Plan area. The project consisted of roadway improvements and realignment, which would result in the fill of wetlands and the relocation of roadside ditches and temporary impacts to ephemeral drainages. In addition, Ms. Loeser prepared the CWA Section 401 Water Quality Certification for the Regional Water Quality Control Board and the Streambed Alteration Agreement for the Department of Fish and Game. Ms. Loeser served as liaison between the project proponent/developer and agencies; all permits were obtained.
