Environmental Rules in Beaverton, OR

Beaverton maintains 115 local ordinances across all categories, and 2 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Beaverton falls on the strict-to-permissive spectrum compared to other cities.

Stormwater Management

Any Beaverton property connected to the public storm drainage system must pay a monthly maintenance charge set by council resolution, with a defined path to disconnect if runoff is retained on-site.

Key details: Governing sections: BC 4.06.010–4.06.040. Charge basis: Monthly, set by council resolution. Disconnection path: On-site retention verified by City Engineer. Applies to: Any property draining to public system.

Failing to pay the storm drainage charge is treated like other City utility delinquencies and can lead to collection action; the charge continues until the City Engineer confirms a valid disconnection.

Flood Zones

Beaverton participates in FEMA's National Flood Insurance Program and regulates development in mapped Special Flood Hazard Areas under the Beaverton Development Code Chapter 60.05 (Special Districts and Overlay Zones, including Floodplain). The primary Beaverton floodplains follow Beaverton Creek, Fanno Creek, Johnson Creek, and Hall Creek (FEMA Zone AE). New construction and substantial improvements in SFHAs must meet elevation, floodproofing, and Oregon-specific PICM (Pre-Implementation Compliance Measures) habitat-protection standards.

Key details: NFIP Status: Participating community. Local Floodplain Code: Beaverton Development Code Chapter 60.05. Primary Floodplains: Beaverton Creek, Fanno Creek, Johnson Creek, Hall Creek (Zone AE). Substantial Improvement: 50% of pre-improvement market value triggers BFE compliance. Oregon PICM: Habitat/no-net-loss standards adopted by Dec 1, 2024.

Floodplain development without permit, or in violation of elevation, freeboard, or floodway no-rise standards under BDC Chapter 60.05, may trigger stop-work orders, after-the-fact permitting, mandatory removal, and code-compliance penalties. Substantial NFIP non-compliance also risks community probation and suspension from the flood-insurance program.

This is one of the stricter rules in Beaverton's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
