ENVIRONMENTAL (SEPA) DETERMINATION OF
NON-SIGNIFICANCE (DNS)
PROJECT NUMBER: PR20-000002/LUA20-000145
APPLICANT: Jennifer Henning, City of Renton / 1055 S Grady Way, Renton, WA 98057
PROJECT NAME: 2020 Flood Insurance Rate Maps (FIRM) adoption and Revisions to Title IV
PROJECT DESCRIPTION: 2020 FIRM and Regulation Update
The City of Renton is a participant in the National Floodplain Insurance Program NFIP. The NFIP provides affordable
insurance to property owners, renters and businesses located in the regulated floodplain. To participate in the NFIP, a City
or community must adopt and enforce floodplain management ordinances that meet or exceed the minimum
requirements of the NFIP. These requirements are intended to prevent loss of life, loss of property, reduce taxpayer costs
for disaster relief, as well as minimize economic and social hardships that result from flooding.
In May 2020, FEMA notified the City of Renton that a revised Flood Insurance Study (FIS) and Flood Insurance Rate Map
(FIRM) have been completed for King County. The FIS and FIRM will become effective on August 19, 2020. By the FIS and
FIRM effective date, the City of Renton is required to adopt a floodplain management ordinance that meets or exceeds
the minimum NFIP requirements, and request approval from the FEMA Regional Office. The FEMA Regional Office is
required to approve the legally enforceable floodplain management measures that the City adopts in accordance with
Title 44 Code of Federal Regulations Section 60.3(d). The approval of the NFIP State Coordinator at the Department of
Ecology (DOE) is also required.
Compliance with the mandatory minimum requirements of the NFIP, in order to avoid suspension from the program,
obligates the City to take the following actions:
1. Adopt the revised FIRM that will become effective on August 19. The City’s code includes an “automatic adoption
clause” for floodplain map updates as RMC #4-3-050 Section E (Maps) references the 1989 study and “any
subsequent revision”. Hence, the City does not need to take any action specifically for the adoption of the revised
FIRM.
2. Complete the amendments to Title IV, chapters 3 and 11, requested by DOE and FEMA following the Community
Assistance Visit (CAV) that took place in June 2019 and detailed in a letter received in December 2019. The CAV is
a major component of the NFIP where FEMA and DOE staff provide technical assistance and recommendations to
the City to ensure adequate enforcement of floodplain management regulations. The CAV review of Title IV
resulted in a request to add multiple sections.
