Each project below represents a distinct regulatory context, habitat type, or county. Client names are withheld per confidentiality agreements; project details reflect publicly available information.

01
Creek Bank stabilization & Permitting·Napa County·2020

Napa River Bank Stabilization Project

Consulted for a local municipality to obtain permits for stabilizing approximately 200 feet of creek bank on the Napa River to secure and protect an existing sewer line.  Developed a riparian enhancement planting plan designed to benefit special-status anadromous fish and wildlife.

Habitat TypesRiparian corridor and perennial creek.
OutcomePermits secured within 6 months. Project constructed.
02
Wetland Mitigation / CESA Compliance·Sonoma County·2008-2026

Santa Rosa Plain Seasonal Wetland & California Tiger Salamander Habitat Mitigation Project

Identified an off-site mitigation property to create and enhance vernal pool habitat and California Tiger Salamander (CTS) habitat on the Santa Rosa Plain.  The project was to serve as mitigation for a pre-existing violation for one client and mitigation for development of an off-loading facility for another.  The mitigation project proposed to construct approximately 13.81 acres of seasonal wetlands and preserve approximately 2.13 acres of high-quality seasonal wetlands on the project site.

Habitat TypesVernal pool, grassland.
OutcomeIncidental Take Permit and Clean Water Act 404 and 401 permits obtained.  97 percent of mitigation wetlands met success criteria and breeding habitat for CTS was documented.
03
Biological Resources Assessment·Sonoma County·2025-2026

Sonoma Valley Oak Woodland Grading Violation

Assisted various clients with violations issued by the County of Sonoma for unauthorized grading in oak woodlands.   Prepared biological resource assessments for each property as required by the County and prepared oak woodland mitigation plans.

Habitat TypesOak woodland.
OutcomeResolved violations.
04
Coastal Permit & Biological Assessment·Sonoma County·2026

Timber Cove Coastal Permit

Prepared biological assessment and mitigation plans for private landowners within the Coastal Zone.  Designed reduced setback alternatives to Environmentally Sensitive Habitat Areas identified within the Local Coastal Plan.

OutcomeLand Use Permits for single-family homes obtained from County.
05
Regulatory Permitting·Lake County·2025

Middletown Wetland Delineation and Biological Resources Assessment
