FINDINGS AND CONCLUSIONS: Criterion No. 1: That the variance is necessary because of exceptional or extraordinary circumstances regarding the size, shape, topography, or location of the subject property; or the location o( a pre-existing improvement on the subject property that conformed to tne zoning code in effect when the improvement was constructed. a. Findinqs: The proposed buil�iing is located at the City of Everett sewage treatment (acilily. 1'he site is over 450 acres in size however, it is surrounded on three sides by bodies of water, and also contains severa; environmentally sensitive features. The entire parcel is within the Rural Flood Fr'nge District designated as such due to periodic flooding of the Snohomish P.iver, and therefore is subject to addilional regulations of the Federal Flood Insurance Program, as well as the Shoreline Master Flan. The existing facility is the only one of ils kind within the Cily of Everett. Much of the site is already occupied by approximately 190- acres of wastewater treatment ponds which have dike elevations oi approximately 3.48 feet. The seven-acre mechanical treatment pror,�ss station and administration building are built on fill to provide a finished floor elevation of approximately 16.62. The area occupied by the mechanical treatment facility is unavailable for the proposed building location due ?o a thirty million dollar expansion proposed over the next couple of years for the treatment processing facility. The areas surrounding the � jministration building are limited in their development potential due to Shorel�ne Jiirisdiction and irsuRicient buildinc� space, which leaves the area to lhe east of the administration huilding the o�ily possible building location within an exiting flood protection area. This area however is limited in building siting by several factors, including: 1) a PUD transformer and switch gear facility to the soulh: 2) a 54-inch sewer influent line to the west; 3) an existing drainage swaie to the north along 4'" Street SE; 4) site shape and layout of existing features. AF�proximalely 5,700 cubic yards of fill will be used to elevate the building a minimum of two feet above the 100-year (lood elevalion. Seventy six (76) concrete piles wili support and anchor the building's finished floor elevation to a 16.95 foot elevation, approximately 4.4 fe�t above the 100-year flood elevation. All of the existing treatment dikcs are at elevaiinns of approximately 8.48 (eet. The proposed cuilding will comply with lhe requirement for all structures to be two feet above the regulatory ilcod protecticn elevation. The proFosed variance is for the land that lies beyond the structure, as well as the driveway. The siting of the new facility is limited to the proposed location based upon existing site features, as well as existing and proposed deve�opment tr�=nds cr site. �
