Preffminary Plat Review: Summerset ~k~feadows ~epternber 30, 2005 Page 3 of 8 Lot S~zes: The m/n/mum lot size for a R-1 Single Family Urban. lot is 10,800 square feet. Most of the proposed single~family lots are less than the required lot size {139 o£ 154 lot). You are request/ng the smaller single-family lot sizes as part of' the PUD'. The sing£e~ ' fam!ly lots range from 7,952 sq. ft. to 14,698 sq. ft. with an average lot size between 8900 to 9,000 square feet. Townfiomes do not have minimum lot size. From the submitted prelim/nary plat, it appears that the townhome units will be divided by the' Common' · Interest Community (CIC) plat. Please confirm if this is the' case. Lot Dimensions:' The minimum lot width for R.~I Single Family lots is 80 feet. as · measured at front yard setback. It appears that all of the single,family lots are less than 80 feet wide at building setback. The lots average about 61 feet in w/dth a~ the front building setback line. You are requesting this smaller' lot w/dth as part of the PUD. re.ques? in order to foster a neighborhood design element as well as to make up for the loss of'nearlY 14 acres b. ei.n.g given t.o the City.fg.r the future Mississippi River Bridge c?oss~ng. Under City- Code; there is:not a minimum lot wi.c~th'/'edtuirement f6r to~vnhomes. Set/backs: -Per Staff direction, you have' prepared a setback exhibit (pg. I7-18-of 35).', Setbacks' appear to be met for al!' of the units except for two areas (Lot 1, Block 3. and Lot 5, Block 6). The r~quired Comer side Yard setback is 30 feet. The'Developer is proposing. that that these two lots have a 25-foot comer side yard setback.. This deviation from code will be .required to have approval as part of the PUD request. Grading and Drainage Plans: The project will require a Permit_from the ~.0wer Rum.. River Water Management' Organization: The permit will address the storm' water calculations as well as the wetland, filling and mitigation as noted below. Review of the ' grading tabulation indicates that all of the IOts: have the' ,m4nimurn .2 foot-vertical separation between the nearest 100 year water, level and the lowest floor elevation. This project will also reqUire:an ._NPDES II pCrmi~ from .the Mirmes0ta. Pollution Control Agency. A copy of tt{e perm/t' appl~cation must be provided: tO the 'city.' The :~ermit must be transferred if the prop~erty, is sold during development or when the contractc~rS working ~on site change. The tf, pical p~rmit is v.alid, seven, days after the application, is mailed; however, there are specific conditions under wh/ch a longer.-. revieTM Period is required. The~e specific condit[bns should be investigated during the review process so that construction is 'not delayed waiting for this permit. The park grading in the northwest comer' should' be adjusted to move th~ drainage Swale . away from the middle of the park.- An exhibit must be prepared showing how the park. couid be developed with parkir/g, a play tfeld and other amefiities. The park area may be ' more useful to the city if the narrow triangular' area north of lots' 8 -' 11 was'reconfigured _ by losing a lot and extending the remaining lot lines to the'r/ght of way. The drainage and utility easements along rear lot lines must cover the area anticipated to be inundated during the i00 year event. Please review the anticipated flow width in drainage swales and adjust the easements accordingly. 32
