Stormwater compliance ensures runoff is managed safely and that Rainwise rebates stay valid. Osprey Exterior partners with municipal reviewers to document every detail, from downspout routing to infiltration trench dimensions. Start with our services overview to understand how drainage, gutters, and cisterns align.
Seattle requirements
Seattle Public Utilities requires proof that new systems disconnect from the combined sewer and infiltrate on-site. RainWise projects must include before-and-after diagrams, calculations, and photos. We host all files in a secure client portal for rapid sharing with inspectors.

Eastside city highlights
In Bellevue, code section 24.06 outlines detention and infiltration standards. Redmond and Kirkland focus on pre-application meetings and erosion control. Our compliance team keeps templates updated for each jurisdiction.
Documentation you’ll need
- Site assessment: Photos of downspouts, grading, and pervious surfaces.
- Design packet: Drawings that show pipe sizing, cistern layout, and overflow routing.
- Post-install checklist: Signed inspection forms, rebate paperwork, and maintenance schedule.
Pair these documents with our project portfolio to see how code compliance leads to fast approvals.
Staying compliant long term
Annual gutter cleaning, cistern inspections, and reviewing seasonal maintenance checklists keep systems operating. Osprey Exterior offers service plans and cistern tune-ups to maintain warranty and rebate status.
