Answers to the questions we hear most often from property owners, buyers, and developers across Western Washington.
Getting started
What does Eastside Environmental Pros actually do?
We are an ecological consulting firm specializing in wetland delineation, stream and shoreline classification, and environmental permitting across all Western Washington counties. We identify regulated critical areas on your property, assess how they affect your project, and prepare all the documentation needed to move through the permitting process — from feasibility through permit approval.
Do I need an environmental consultant for my project?
If your property has — or may have — wetlands, streams, shorelines, or other critical areas nearby, most local jurisdictions in Washington State will require a critical areas study or wetland delineation before they issue a building permit. Hiring a consultant early saves time and often money, since it prevents costly redesigns after an architect or engineer has already developed plans.
What counties do you serve?
We serve all Western Washington counties, with the majority of our work in King County, Snohomish County, Pierce County, Whatcom County, and Skagit County. If you’re unsure whether we cover your area, contact us — we’re happy to let you know.
The process
What is a wetland delineation and why do I need one?
A wetland delineation is a field investigation that precisely maps the boundaries of any wetlands, streams, or shorelines on your property. The results determine where you can build and what protective buffer distances apply. It’s required by local, state, and federal agencies before most permits involving development near water features can be approved.
What is a Critical Areas Report (CAR) and when is it required?
A Critical Areas Report is a formal document required by most jurisdictions when wetlands, streams, steep slopes, or other regulated features are on or near your project site. It documents the findings of the delineation and explains how your proposed development will — or will not — impact those areas. We prepare CARs as part of our standard permit support services.
What’s the difference between a feasibility study and a full delineation?
A feasibility study gives you a general picture of buildable area and constraints — ideal for early-stage planning or pre-purchase decisions. A full delineation produces the precise, flagged boundaries required by permitting agencies. We offer three tiers: a basic site walk with map, a feasibility reconnaissance, and a feasibility delineation that includes all the fieldwork needed for permit submittals in a single visit.
Will you need to access my property? What does a site visit involve?
Yes — field visits are typically required to conduct an accurate delineation. Our ecologists walk the property, assess soils, vegetation, and hydrology, and place flags marking wetland and stream boundaries. Most residential site visits take between 2 and 6 hours depending on property size and complexity.
Cost & timing
How much does a wetland delineation cost?
Costs vary based on property size, terrain, number of critical features present, and report complexity. We provide transparent, upfront estimates before any work begins. Contact us to get an estimate specific to your property.
How long does the process take from start to report delivery?
For most residential projects, we can complete fieldwork within 1–2 weeks of engagement and deliver the report within 1–3 weeks of the site visit. Time-sensitive requests — especially pre-purchase feasibility studies — are prioritized and can often be scheduled within days.
Do I need to hire a surveyor in addition to an ecologist?
Not always. We use high-accuracy GPS equipment that can locate delineation flags to within 12 inches, which is sufficient for many project types. However, some projects such as plats and short plats do require a licensed surveyor — we’ll let you know upfront if that applies to your situation.
Permits & agencies
Which government agencies are involved in the permitting process?
Depending on your project, you may interact with your local city or county planning department, the Washington Department of Ecology, the Army Corps of Engineers, and potentially the U.S. Fish and Wildlife Service. We maintain strong working relationships with staff at these agencies across Western Washington.
What is a JARPA and do I need one?
A Joint Aquatic Resource Permit Application (JARPA) is a combined permit application submitted to Washington State and federal agencies when your project involves work in or near waters. Not every project requires one — we’ll let you know during our assessment whether a JARPA applies to your situation.
What happens if there’s already a code enforcement case on my property?
We can help. We assess whether a violation actually occurred, and if so, develop a remediation plan to bring the property back into compliance. We’ve worked on numerous code enforcement cases across Western Washington and understand how to navigate the process efficiently.
Purchasing property
Should I get a wetland study before buying a property?
Strongly recommended. Critical areas like wetlands and streams can significantly restrict what you’re allowed to build — and those restrictions aren’t always visible on a plat map. We specialize in pre-purchase feasibility studies and prioritize them in our scheduling so buyers can get answers before closing.
Can you conduct a study on a property I don’t own yet?
Yes — as long as the current property owner provides written permission to access the property, we can conduct a feasibility study on behalf of a prospective buyer. Contact us as early as possible in your due diligence process.
A previous wetland study gave us a large buffer. Can it be re-evaluated?
Yes, and it’s often worth doing. Buffer widths depend on wetland category and rating — a more thorough or updated rating can sometimes result in a significantly smaller buffer, opening up more buildable area. We’ll give you an honest assessment of whether a re-evaluation is likely to help in your case.
