Wetland, Wildlife & Shoreline Consulting

feature image

Our wetland, shoreline and wildlife biologists provide expert consulting services throughout the Puget Sound and Strait of Juan de Fuca.


We work with residential landowners, homeowners, developers, and the building community in a variety of protected environments. These may include wetlands, shorelines, streams and wildlife corridors, FEMA Flood Zones, and habitats for protected animals. We work with you from feasibility and planning to construction and monitoring.

Call us regarding your wetland or shoreline project today

We perform wetland delineations, no-net-loss assessments, shoreline impact assessments, habitat management plans, and mitigation plans for properties throughout the Puget Sound and Strait of Juan de Fuca.

Steep Slope Inspection

We inspect steep slopes and bluffs across our state for vegetation and drainage concerns. Click here for more information.

Shoreline Biologists

Shoreline consulting is generally required whenever building near a Shoreline of the State. Services may include an ordinary high watermark study, no-net loss report and habitat management plan.

Wetland Delineation and Rating

A wetland delineation and rating are required whenever developing near a potential wetland . A delineation identifies the boundary of the wetland and the rating calculates the buffer width. After the delineation and rating, a mitigation plan may be required depending on what impacts are planned.

Feasibility Studies

Feasibility studies are generally performed while purchasing real estate to better understand the environmental risks on a property. Find out before you purchase if your intentions are doable or not. This applies for wetlands, streams and shorelines.

No Net Loss (NNL) Assessments

A net loss assessment (NNL) is a study generally required during shoreline development. This study documents your shoreline’s existing conditions and describes how your proposed actions will increase or diminish those baseline functions. Mitigation is often required to result in a “no net loss of shoreline function.”

Ordinary High Water Mark (OHWM) Delineation

An ordinary high watermark of a Shoreline of the State or stream is commonly used as the stratification between aquatic and upland habitat. The OHWM is determined by a qualified biologist on site examining a combination of vegetative and hydraulic factors. We place markers at the OHWM for a licensed surveyor to collect for a site plan requirements.

FEMA Habitat Assessments

A FEMA habitat assessment is required whenever planned development occurs within a FEMA Flood Zone. These unique areas can be along a marine or freshwater shoreline and are mapped on a federal level. The FEMA Flood Zone has no buffer, you’re either within the area and require a habitat assessment, or you’re outside and do not.

Biological Site Assessments (BSA)

Biological site assessments are commonly required when impacts like development occur within multiple regulated environments, like a Shoreline of the State, a wetland and a Aquatic Habitat Conservation Area. These studies are generally performed in two phases. Phase 1 includes identifying existing conditions, locating critical areas, and rating them.

Fish Exclusion, Removal and Relocation

We are certified by the Washington Department of Transportation to carry out fish electrofishing and fish exclusion required for logging, culvert replacement, and other infrastructure.
