TRANSPORTATION/PLANNING: Rock Region Metro: No comments received. Planning Division: No comments. H. ANALYSIS: The applicant proposes to subdivide 27.46 acres of property into 85 lots for single family development. The subdivision will include Phases 7 through 8 of the Copper Run residential development as follows: Phase 7 – 41 lots Part of Tract O Phase 8 – 44 lots Part of Tract O The proposed lots will range in size from 0.13 acre to 0.17 acre. There will be 5,120 linear feet of new streets with the proposed development. A 90 foot wide right-of-way will be dedicated along the south property line of the overall property to accommodate a future east/west minor arterial roadway, as shown on the City’s Master Street Plan. A 30 foot wide secondary access will extend from Ironwood Way, between Lots 134 and 135, to the future east/west minor arterial roadway. The applicant is requesting a variance to advance grade Phase 8 with the grading of Phase 7. The applicant notes that the advance grading of Phase 8 will reduce the amount of earthen material that will have to be hauled across city streets. Staff supports the advance grading request. Sections 36-254(d) 1 thru 3 of the City’s Zoning Ordinance requires minimum front building setbacks of 25 feet, minimum rear building setbacks of 25 feet and minimum side setbacks of 8 feet or 10 percent of the lot width. The applicant is requesting a variance to allow 20 foot front and rear setbacks and 5 foot side setbacks for the lots are wider than 50 feet. Staff is supportive of the requested variance, as the proposed setbacks are the same as those within the existing Copper Run Subdivision. The applicant is also requesting a variance to allow a reduced lot area for several of the lots within Phases 7 and 8. Several of the interior lots (Lots 302-320 and 323-341) have proposed lots areas of 5,750 square feet. The minimum lot area required by doe is 6,000 square feet. The requested variance is a very minor decrease in lot area. Staff supports the variance request. November 9, 2023 ITEM NO.: 1 (Cont.) FILE NO.: S-1844-F 8 To staff’s knowledge there are no outstanding issues associated with the proposed preliminary plat. Staff is supportive of the proposed preliminary plat.
