CASE REQUEST FOR A VARIANCE FROM SIDE YARD SETBACK REQUIREMENTS AI~D IMPERVIOUS SURFACE AREA RESTRICTIONS; CASE OF BILL DUBATS, LAKEVIEW ENTERPRISES, INC. By: Zoning Administrator Sylvia Frolik Background: Bill Dubats of L~keview Enterprises, Inc., has applied for site plan approval to construct self- service storage facilities on Lot 3, Block 3, Riverside West. The subject property is located in the Critical River Overlay District and as such, the impervious surface area is restricted to 30% of the lot area. Mr. Dul:;atS' site plan reflects an impervious surface area of 90%. In addition, the p~operty is zoned B-3 Highway Business and the side yard setback in this district ~s 10 feet. Mr. Dtlbats ~s propomng to develop the site with a zero lot line configuration along the north side yard. Observations: This developmen would be an expansion of the self-service storage facilities existing on Lots 1 and 2 of Riversid6 West. In 1987, a variance was granted to the setback requirements in order that the storage fac~hqes to be developed on Lot 1 could be placed w~th a spacing consistent with the structures already constructed on Lot 2. Likewise, Mr. Dubats is proposing to continue the spacing consistency between structures established on Lots 1 and 2 and hence a variance to the side yard setback is necessary along the north property line of Lot 3. The property is inithe Critical River Overlay Distr/ct and is restricted to a 30% impervious surface area which inch/des structures and pavement. The site plan proposes approximately 90% impervious surfa~ area. The main purpose of the impervious surface area restriction is to prevent pollution of the Mi/ssissippi River from surface water runoff. The original drainage plan submitted by the applicant v~ould have resulted in a runoff discharge of 3.8 cfs in a 2 year storm. Mr. Dubats has worked with the City Engineer to modify the drainage plan to provide for a detention volume consisting of a trehch lined with block that will reduce the surface water discharge into the existing storm water syste,im to 1.7 cfs. An additional pu~ose of the development restrictions established in the Critical River Overlay District is to mairf~ain a minimum amount of development density in order to preserve the natural aesthetics of the r~ver corr/dor. The subject property is not visible from the fiver. Mr. Dubats development plan has been forwarded to the Department of Natural Resources, Metro Council and the Environmental Quality Board for review and comment. At the date of this writing, no response comn~ents have been received by the City.
