SITE INFORMATION The subject development site is a 0101.1 acre parcel located inside the northern 'edge of the Springfield Urban Growth Boundary (UGB). ' The Assessor's map description is 17-03-24-00, Tax Lot 500, and the parcel is municipally addressed as 2833 20th Street. Twentieth Street terminates in a cul-de-sac bulb at the southern edge of the subject property. The site is entirely within the mapped FEMA 100-year floodplain for the McKenzie River, and lies between the 450 to 453 foot Base Flood Elevation (BFE) levels as shown on FIRM Map 41039C1'153F dated June 2, 1999: The applicant is requesting a Floodplain Overlay District approval to construct a residential dwelling and in- ground swimming pool near the florthern edge of the property, Established base flood elevations will be used to determine the futUre building floor elevation and other appropriate floodproofing measures for the site, FEMA flood mapping (FIRM Map 41039C1l53F, Panel 1153, dated June 2,1999) establishes a base flood elevation ofbetween450 feet (west of the site) and 453 feet (east ofthe site) for the property. The applicant has interpolated the flood information and proposes a BFE of approximately 452 feet for the'site. The applicant's site diagram depicts existing ground elevations at the corners of the proposed building envelope that range from 448.2 feet to 449.0 feet. To meet FEMA floodproofmg requirements, the finished floor eJe:vation is to be at least one foot(12 inches) above the base flood elevation (-452 feet). The applicant is proposing a finished floor elevation of 453.1 feet. ' APPLICABLE STANDARDS AND CRITERIA The applicani seeks approval for construction of a single family home and in-ground swimming pool. The applicant is not proposing significant grading or placement of fill. The property formerly contained a mobile home, and existing utilities will be extended to serve the proposed dwelling, including water, electricity and telecommunication lines. It is not clear from the applicant's submittal whether the existing septic system will be used to serve the proposed dwelling, or if a new system will be installed. Septic systems may have to be floodproofed in accordance with FEMA requirementS. In accordance with SDC 3.3-410, the regulations of Section 3.3-400 apply to all areas of special flood hazard within the City and its urbanizable area, Where the regulations and permitted uses of an underlying district conflict with those of an overlay district, the more restrictive standardS'Shall apply, Finding I: Areas of special flood hazard are defined in SDC 6.1-110 as: "The land in the floodplain subject to a one percent or greater chance of flooding in any given year. Designation on maps always includes the letters A or V," Finding 2: SDC 6.1-110 defmes base flood as: "The flood ha~ing a one percent chance of being equaled or exceeded in any given year.
