The design of the proposed subdivision is in substantial conformance with the applicable zoning regulations. 3. The design of the subdivision and the type of associated improvements will not likely cause serious public health problems because water and sanitary facilities services will be available to the new parcel. 4. The density of the subdivision is physically suitable for the proposed density of the development. 5. The design of the proposed subdivision and improvements are not likely to cause substantial environmental damage or subsequently injure fish or wildlife or their habitat since this property is in an area where residential development has previously occurred. 6. The design of the proposed subdivision and proposed improvements will not conflict with easements, acquired by the public at large, for access through or use of, property within the proposed subdivision. Variance This variance does not constitute a grant of special privilege inconsistent with the limitations on other properties in the area and the R -40; Single Family Residential District and the R -65; Single Family Residential District in which the subject property is located. 2. Because of the following special circumstances applicable to this specific property, strict application of the zoning regulations would deprive the subject property of rights enjoyed by others in the general vicinity and /or located in the same zoning district: a. A two parcel subdivision of the subject property could be accomplished without the need for approval of a variance. However, the variance would allow for a shared driveway which would reduce the overall amount of new impervious surface area and associated stormwater runoff. The gross square footages of the subdivided parcels would meet the minimum lot size requirements for their respective zoning districts and the parcels would have an average of 1.25 - -/- acres per unit, which exceeds the one unit per acre standard established under the Residential — Country Estates General Plan land use designation. b. There are existing lots within the adjacent area that are less than one acre in net or gross area. The size of the new subject parcels would be in character with the existing surrounding lots within the same zoning district. PAGE 3 OF RESOLUTION NO. 44 -2013 3. This variance is in substantial conformance with the intent and purpose of the R -40; Single Family Residential District and the R -65; Single Family Residential District in which the subject property is located since the variance will allow for a two parcel minor subdivision that is consistent with the development pattern of the neighborhood. CONDITIONS OF APPROVAL Conditions of approval with an asterisk ( *) in the left -hand column are standard project conditions of approval.
