5.4 ITEM 5.4. ity of A River MEMORANDUM TO: Planning Commission 61 FROM: Kendra Lindahl, Zoning AssistanA i DATE: May 28, 1996 SUBJECT: Variance Request by Diane Tyson and Michael Schwingle, Public Hearing Case No. V 96-04 Request The applicant is requesting a variance for a 5 foot setback from the garage, and a variance for a 35 foot shoreland setback from the Elk River for a septic system. Location • 18741 Yankton Street NW, Part of the NW 1/4 of the NW 1/4, Section 31, Township 33, Range 26, PID #75-131-2205 and 75-463-0080. Zoning/Land Use R-lb (Single Family Residential)/MR (Medium Density Residential) Attachments • Location Maps • Site Plan • Letter from Jon Christensen Background The existing septic system at 18741 Yankton St. NW is failing. Staff inspected the site with the installer, Leo Deschenes, and found that there is not sufficient room for the applicant to place a new septic system on the property and still meet all required setbacks. Staff reviewed options with designer Jon Christensen, and we believe that his proposal is the most logical solution. • 13065 Orono Parkway • P.O. Box 490 • Elk River, MN 55330 • (612) 441-7420 • Fax: (612) 441-7425 Memo to the Planning Commission Page 2 May 28, 1996 The applicant is proposing to purchase the adjacent parcel of land (Lot 10, • Sixth Plat of Camp Cozy) for the purpose of providing room for the septic system. The purchase of this land is contingent on approval of the variance. The proposed location is the only available location that is above the watertable and floodplain. The designer is proposing a pressurized system. The proposed septic system should have enough lateral to treat coliforms and nitrates. The system should be graded away from the river to reduce any potential contamination problems. The current ordinance requires a 75 foot setback from the ordinary high water mark for septic systems. The applicant is requesting a 40 foot variance for a 35 foot setback from the ordinary high water mark. The applicant is also requesting a variance for a 5 foot setback instead of the required 20 foot setback from any structure. Staff had a preliminary discussion with Dan Lais of the DNR-Division of Waters and indicated that, in staffs opinion, this variance is the best solution available. The DNR will review this item and get a letter to the City Council outlining their position. • Variance This property is subject to the normal standards found in section 900.40 of the Elk River Ordinance which states that a variance may only be granted if it meets those five conditions. Because this property is in the Shoreland Management area, Council shall also consider the following: I. whether the applicant has reasonable use of the land without the variance; II. whether the property is used seasonally or year-round; III. whether the variance is being requested solely on the basis of economic considerations; IV. the characteristics of development on adjacent properties. In staffs opinion, this applicant very clearly shows a hardship in that there is no room to place a new septic system on the property. They are required to have a septic system on site and the only way they will be able to do that is to get a variance on the setbacks. If the variance is not granted, the applicant will lose all use of the land as a residence. • s:\planning\ke n dra\v96-04.doc Memo to the Planning Commission Page 3 May 28, 1996 • Recommendation Staff recommends approval of the variance for a 5 foot building setback and a 35 foot shoreland setback for the purpose of installing a septic system with the following findings and conditions: Findings 1. Literal enforcement of the ordinance would cause undue hardship by denying the applicant full use of the property. Without a variance, no septic system can be placed on the property and the property would not be usable as a dwelling. 2. The hardship is caused by special conditions of the land which make the proposed location the only available site above the watertable and floodplain. 3. Literal application of the ordinance would deprive the petitioner of rights enjoyed by other property owners in the same district by denying them use of their land as a residence. 4. The variance will not adversely affect the neighborhood or residents of the city and will be in keeping with the spirit and intent of the ordinance. Replacing the failing septic system will reduce any harmful III environmental impacts caused by the failing septic system. Conditions In order to protect this environmentally sensitive area, staff recommends approval with the following conditions: 1. Adjacent property will be purchased and combined with the existing lot for location of the drainfield. Applicant will provide the city with a copy of the lot combination prior to receipt of a building permit. 2. Septic system will be constructed according to the conditions outlined in the letter from Jon Christensen. 3. The top grade of the septic system will be graded away from the Elk River. 4. Approval of this project is contingent on DNR approval. • s:\planning\ke n dra\v96-04.doc 01/01/89 05: 31 PAGE 01 Page._ of Client l4aa F 1t.) a - 1A��aat1� �v�� • Property 1 Y Z t ut1 c e Q.o 22 I \I"\d'q u1. is n`tiQeSim C..bla nu 3 SAcv 501 tea 'vvw� c'irai' Vcii(17 r^ s ��3� t± IravA `��.9 N-�v-w �^+� �Q X`""'x � S J* ti�m z S lnu .,► � .
