San Bruno Mountain HCP

One of TRA's areas of special expertise is habitat conservation plans (HCPs) for endangered species. Habitat conservation plans are authorized under the federal Endangered Species Act (Section 10(a)) for take of listed endangered or threatened species on private lands. We prepared the first two HCPs for endangered species, the San Bruno Mountain HCP (1982). and the Coachella Valley Fringe-toed Lizard HCP (1985).

Both of these plans supported applications for Section 10(a) permits which were subsequently approved by the U.S. Fish and Wildlife Service. Based on the San Bruno Mountain experience, the Endangered Species Act (ESA) was amended in 1982 to include a provision for an incidental take permit supported by an HCP. For our second HCP, the Coachella Valley Fringe-toed Lizard HCP, TRA received an Outstanding Planning Award from the Inland Empire Chapter of the American Planning Association.

Placer County Conservation

Since 1998, TRA has been providing assistance to the County of Placer on two important projects that will guide the future of the County: 1) the Placer Legacy Open Space and Agricultural Conservation Program and the Placer County Conservation Plan, a joint Habitat Conservation Plan/Natural Communities Conservation Plan. For the Open Space Program we assisted the County with a GIS analysis and mapping of resources. For the PCCP, TRA has participated in focused interagency meetings meant to direct the scope and direction of the PCCP. We designed a series of GIS models forecasting habitat loss by vegetation community type and mitigation scenarios for analysis under the Plan as well as a GIS database of the resources present in the plan area. In 2004, we prepared a Conservation Strategy Overview and in February we published a full Agency review draft of the PCCP.


Headwaters Forest

From 1996-1999, TRA provided assistance to the State of California Resources Agency for the Headwaters Forest project. We prepared a conservation strategy for the marbled murrelet, Coho salmon and other species of concern; provided technical review of the HCP, and reconciliation of the HCP and Sustained Yield Plan (SYP). We also provided administrative review of the EIS/EIR (prepared by others). A key component of the EIS/EIR was the preparation of the Mitigation and Monitoring Plan, which specified exactly what measures are to be taken to reduce all listed impacts to less than significant levels.


Land Use and Economics Study
Grassland Ecological Area
Merced County, CA

In 2001, TRA produced a Land Use and Economics Study, jointly funded by the Grassland Water District, the Packard Foundation and the Great Valley Center. It may be the first of its kind to provide a comprehensive picture of the economic values of wetlands in the County, and their impact on the local economy. These non-urban land uses produce a net economic benefit to the local economy, whereas urban development, particularly sprawl type residential development, produces a net economic loss to local government. The study will benefit stakeholders by streamlining project review and improving the certainty of land use decisions. The work products include a final report, a public information booklet, and a workshop for the public and government stakeholders.


San Mateo Coastal Annexation Environmental Impact Report

The Midpeninsula Regional Open Space District is a public agency that acquires and manages open space resources in Santa Cruz, Santa Clara and San Mateo counties. The District proposes to extend its boundaries to include the majority of the San Mateo County coastside, approximately 140,000 acres, in order to acquire and manage land and easements for the preservation of open space and agriculture, and the protection of sensitive resources. The proposed annexation to the District is subject to approval by the San Mateo County Local Agency Formation Commission (LAFCo).
