Tri-Cities Subdivision Plat Guide - Washington Bylaws
Preparing a subdivision plat in Tri-Cities, Washington requires following state law and local planning rules early in the design process. This guide explains typical requirements, timelines, review steps, and who enforces plat approval in Tri-Cities jurisdictions (Kennewick, Pasco, Richland). Use it to plan checklist items, coordinate with the city planning office and county auditor, and reduce delays when creating new lots for sale or development.
Overview: What a subdivision plat does
A subdivision plat legally divides a parcel into new lots, sets public right-of-way and easement dedications, and creates the recorded map that a county auditor files. Expect surveys, engineering, public notice, and coordination with utilities and the city planning department.
Pre-application & Early Steps
- Prepare an initial survey and conceptual site plan showing lot lines, roads, easements, and existing structures.
- Contact the local planning department for a pre-application meeting to confirm submittal requirements and standards.
- Check zoning and comprehensive plan designations to confirm minimum lot sizes, density, setbacks, and permitted uses.
- Coordinate with public works or engineering for street, drainage, and utility improvement requirements.
Required Materials for Submittal
- Preliminary plat drawings and legal description prepared by a licensed surveyor or engineer.
- Title report, any existing easement instruments, and proof of ownership.
- Application fees and deposit for review. Amounts vary by city.
- Environmental and SEPA checklist if applicable under state law.
Review & Approval Process
Typical steps: submittal of preliminary plat, technical review (city engineers, utilities), public notice and hearings (if required), conditional approval with required improvements or bonds, final plat submittal, signatures, and recording with the county auditor. Local codes set specific deadlines for resubmittal responses and recording time windows.
