Clearly some hardcover variance is required to allow <br />any driveway on the property. <br />2. With the driveway hardcover variance, 2 units <br />(1 existing + 1 new) could be built meeting all <br />other requirww nts and without further variances. <br />3. Allowing three units as in the previously approved <br />plat would require a nominal 10% hardcover variance <br />within the buildable area. <br />4. Allowing four units as proposed would require a <br />s <br />nominal 201 hardcover variance. <br />5. Five units as might be allowed by gross lot area <br />density is clearly not physically practical within <br />the setback rec,uirements. <br />Recosmended Considerations for Preliminary Plat Approval <br />1. Determine reasonable density to be allowed <br />` <br />a) 2 u- �o with driveway hardcover var nce only <br />b) 3 u, j with driveway and 10% structural hardcover variance <br />s <br />e) 4 units with driveway and 20t structural hardcover variance <br />2. Conditioned upon <br />a) drainage improvements per plan, including holding ponds, <br />relocated and resloped driveway, building eaves troughs, <br />maximum hardcover square footage depending upon density, <br />and orosion control meauures. MCWD munt approve drainage plan. <br />b) new driveway with turnaround per plan <br />1) minimum 12' paved width for 2 units <br />2) minimum 18' paved width for 3 or 4 units <br />c) dedication of new City cul de sac and ritjht <br />of way including paving , f utrect anti cul de <br />sac and rip rappinn ut whore ab in previous <br />applications. <br />
