Critical Areas & Environmental
Wetlands, slopes and buffers, handled early instead of expensively
Critical areas don't make a site unbuildable. They make it a different site than the one you thought you were buying, and the difference is worth knowing early.
What counts as a critical area
Washington jurisdictions adopt critical areas ordinances under the Growth Management Act, and the categories are consistent even when the specifics aren't: wetlands, fish and wildlife habitat conservation areas including streams and their buffers, geologically hazardous areas such as steep and landslide-prone slopes, frequently flooded areas, and critical aquifer recharge areas.
What varies by jurisdiction is buffer width, how buffers are measured, what averaging or reduction is allowed, what mitigation ratios apply, and what triggers a full report versus a screening. Two adjacent parcels in different jurisdictions can face materially different requirements for the same wetland.
How CLD works these projects
Screening first — desktop review of mapped critical areas, soils, hydrology and aerials to determine whether a formal delineation is needed at all. Where it is, CLD scopes and coordinates the wetland biologist, geotechnical engineer, or habitat consultant, reviews their reports before submittal, and makes sure their conclusions are consistent with the site plan.
Then the harder part: negotiating the development footprint. Buffer averaging, reasonable use provisions, mitigation sequencing and enhancement plans are all tools that can recover buildable area — but only if they're raised at the right point in the process and supported properly.
Mitigation and monitoring
Where impacts are unavoidable, mitigation comes with a plan, a planting schedule, performance standards, and multi-year monitoring obligations that outlive construction. CLD makes sure those obligations are understood and budgeted before they're accepted as permit conditions, and coordinates the monitoring reports afterward.
What you get
- Desktop critical areas screening and constraint mapping
- Scoping and coordination of wetland, geotech and habitat consultants
- Technical report review before agency submittal
- Buffer averaging and reduction strategy where code allows
- Mitigation plan coordination and permit condition review
- Monitoring obligation tracking after construction
Bring CLD in when
- Mapped wetlands, streams, or steep slopes touch your parcel
- A buffer is eating the part of the site you planned to build on
- You received a critical areas report and don't know what it means for yield
- Agency review flagged an environmental issue you weren't expecting
Common questions
The county map shows a wetland on my property. Is it buildable?
Often yes. Mapped wetlands are frequently inaccurate at parcel scale, and a formal delineation sometimes finds a smaller wetland, a lower category, or none at all. Even where one exists, buffer averaging and site design can usually recover a workable envelope.
Do you perform wetland delineations?
No. Delineations are performed by qualified wetland biologists. CLD scopes the work, coordinates the consultant, reviews the report, and manages how the findings interact with your site plan and permit.
How much buffer will I lose?
It depends on wetland category, rating, and the local ordinance — the range across Washington jurisdictions is wide. This is one of the highest-value things to determine before purchase.
