Zoning File #2053 August 15, 1995 Page 3 Staff has also been advised by on-site septic consultant, Steve Schirmers of S-P Testing, that at least three of the mound sites tested were at an 8 % grade. Septic code specifically says that mound systems must be placed on a slope no greater than 6 % . Staff has advised that in subdivisions that if one of the test sites on one lot within a division is located on a slope greater than 6 % that a variance may be considered for one system. The On-Site Septic Manager has advised that it would be inconsistent for the Department to grant variances for three septic sites on the three lot plat. Based on the limitations of dry buildable area, it is doubtful whether there would be enough area to support a drainage retention facility as would be required for all subdivisions in excess of two lots. Refer to Exhibit B, applicant asks that you consider granting variances to allow the three lot division as proposed. A. Will you grant a lot width variance for Lot 2 as proposed? B. If cul-de-sac is extended westward, would you recommend granting area variances for a new subdivision? ... What of the additional needs for drainage retention on the site? There is nothing unique or unusual about this property to suggest a need for granting variances nor would the granting of these variances be consistent with past actions of the City. The lot layout as proposed is contrived to meet the limited area needs. Applicant would be best advised to proceed with a two lot subdivision, with a back lot/front lot configuration. A back lot/front lot configuration would require a minimum of 5 + acres. The 30' driveway outlot can be placed within the profile of the existing driveway minimizing tree removal and any impact on existing elevations. The Planning Commission may advise applicant to contact adjacent property owners to the north to see if there is any land available to enable applicant to meet requirements of a three lot division. lsv
