Full Breakdown
Under Section 15.16.150, a flood zone development permit must be obtained before any construction or other development, including manufactured homes, within any area of special flood hazard established by the flood insurance study adopted at Section 15.16.070. Applicants must submit plans in duplicate showing the location, dimensions and elevation of existing or proposed structures, proposed water supply, sanitary sewer and utility locations, grading and drainage information, the location of any regulatory floodway, base flood elevation data, and the proposed elevation of the lowest floor of every structure.
Nonresidential floodproofing must be certified by a registered civil engineer or architect, and crawl-space foundations require documentation of flood opening area consistent with FEMA technical bulletins. The city engineer, designated under Section 15.16.130 to administer the chapter, reviews each application to confirm the site is reasonably safe from flooding and that the project will not raise the base flood elevation more than one foot anywhere in the city, per Section 15.16.140. The city engineer may not issue the permit until the applicant pays a development permit processing fee set by council resolution and based on the actual cost of review.
Appeals of the city engineer's decisions go to the city council under Section 15.16.160, and this chapter was originally adopted by Ordinance No. 967 on January 25, 2011.
Violations & Fines
Building or developing land within a special flood hazard area without the required flood zone development permit is a misdemeanor under Section 15.16.080, and the city engineer can pursue remedial action to correct the violation. The city council hears appeals of the city engineer's permit denials or interpretations under Section 15.16.160.
