Short Plats & Subdivisions
Divide land in a way the county will actually approve
A land division is an infrastructure project with lot lines drawn on it. The layout that maximizes lots on paper is often not the layout that survives review.
Short plat, subdivision, or boundary line adjustment
Washington jurisdictions treat these as distinct processes with different thresholds, review paths, and timelines. Short subdivisions divide a parcel into a limited number of lots and generally go through administrative review. Full subdivisions cross that threshold and carry preliminary plat approval, public notice, and a hearing. Boundary line adjustments move lines between existing lots without creating new ones — much faster, and sometimes all a project actually needs.
Choosing the wrong one costs a year. The first thing CLD does is confirm which process the project belongs in, under that specific jurisdiction's code.
Layout is driven by infrastructure, not geometry
Lot yield is constrained by what has to be built to serve the lots: road standards and turnarounds, utility extensions, stormwater facilities and their required footprint, critical area buffers, and open space or tree retention requirements. A layout drawn to maximize lot count without reconciling those requirements gets redrawn during review, and every redraw costs a cycle.
CLD works with the civil engineer and surveyor from the concept stage so the layout that gets submitted is the layout that gets approved.
Preliminary through final plat
Preliminary approval comes with conditions. Final plat approval means every one of those conditions has been satisfied, infrastructure is built or bonded, and the mylar is ready to record. The gap between the two is where most plats lose time — conditions that nobody tracked, bonds that weren't set up, or as-builts that don't match the approved plans.
What you get
- Process determination — BLA, short plat, or full subdivision
- Yield analysis reconciled against infrastructure requirements
- Concept layout coordinated with civil and survey
- Preliminary plat application and hearing support
- Condition-of-approval tracking through final plat
- Coordination of infrastructure construction and bonding
Bring CLD in when
- You own acreage and want to know how many lots it really supports
- A preliminary plat has conditions and no one is tracking them
- The layout keeps changing every time civil or the county weighs in
- You need to know whether a boundary line adjustment would be enough
Common questions
How many lots can I get out of my property?
Zoning density is the starting point, not the answer. Actual yield depends on critical areas, road and stormwater requirements, and access. A feasibility review produces a defensible number instead of a hopeful one.
How long does a short plat take in Washington?
Timelines vary widely by jurisdiction and by whether infrastructure has to be built. The bigger variable is usually the condition-satisfaction phase between preliminary and final approval, not the initial review.
Do I need a surveyor and a civil engineer?
Yes, for anything beyond a simple boundary line adjustment. CLD coordinates them rather than replacing them, so their work is reconciled before it reaches the county.
