Soil Erosion

Program or Regulatory Projects

Environmental review of government programs and regulations to streamline implementation by providing a common analytical foundation for future individual projects

California Department of Water Resources

Small Erosion Repair Program

To facilitate rapid repair of erosion damage on levees along the Sacramento River, DWR worked with the U.S. Army Corps of Engineers, Central Valley Regional Water Quality Control Board, U.S. Fish and Wildlife Service, California Department of Fish and Game, and Central Valley Flood Protection Board to create the Small Erosion Repair Program. The agencies wrote a guidance manual to help DWR maintenance staff implement the program.

Debra Lilly managed the environmental review portion of the approval process. The project team prepared a programmatic EIR to satisfy CEQA requirements, a programmatic biological assessment to satisfy the federal Endangered Species Act, and a programmatic agreement to satisfy the requirements of Section 106 of the National Historic Preservation Act.

El Dorado County General Plan

The El Dorado County General Plan EIR addressed impacts of adopting the proposed general plan under four alternative scenarios.

While with a previous firm, Ms. Lilly evaluated agriculture/forestry, land use, and visual impacts of these scenarios, addressing possible mechanisms for protecting agricultural areas from land use conflicts and requiring a detailed understanding of the economic analysis of development options within the county.

California State Water Resources Control Board

On-Site Wastewater System Regulations

The State Water Resources Control Board drafted California’s first statewide regulations for on-site wastewater treatment systems, with input from regional water quality control boards, U.S. Environmental Protection Agency, and stakeholders (including county health departments and the California On-site Wastewater Association).

As project manager for the preparation of a complex program EIR, Ms. Lilly assisted with agency and stakeholder coordination and development of the analytical approach.

She managed preparation of the analysis, which focused on hydrology and water quality, biological resources, geology and soils, and land use and growth trends. An evaluation of the fiscal impacts of implementing the regulations was also prepared. Following extensive public review and comment, the regulations were redrafted and a Substitute Environmental Document was recently finalized by the agency.

Streamlining Analysis

Conducting program-level environmental analysis of a “program,” or group of interrelated projects with a common purpose, allowed clients to implement individual projects without the need for extensive additional review.

This process, known as “tiering,” saves time and money and creates efficiency in program administration (State CEQA Guidelines Section 15152(a)).
