Bulk Standards Single Family Lot The table below outlines the proposed bulk standards and the minimum requirements for each of the two zoning districts (both for the 65-foot and 80-foot wide districts). Regardless of whether a Zoning Amendment is approved or not, certain modifications to the Preliminary Plat will be necessary. Standard 11 ProposedIF R-1 Residential (MUSA) - 65 R-1 Residential (MUSA) - 80 Lot Size > 0.15 acres 0.15 acres 0.25 acres Lot Width 65 feet IF 65 feet 80 feet Front Setback 25 feet IF 25 feet 30 feet Side Setback IL 7.5 feet:11 5 feetIF- 5 feet Side (Corner) Setback 15 feet IF 25 feet 30 feet Rear Setback 20 feet IF 20 feet 30 feet 1 Does not appear to impact any lots, but the standard should still be updated to match the requirement. Attached Townhomes The table below outlines the proposed bulk standards and the minimum requirements for the R-2 Residential (Medium Density) District. Modifications to the Preliminary Plat are required to ensure compliance with the minimum standards. Standard Proposed 11 R-2 District Requirement Setback from Private Road and public road right of way 25 feet 25 feet Setback from Exterior Development Boundary 30 feet 30 feet Building to Building Setback 25 feet 20 feet Streets and Access As the Planning Commission may recall, the Sketch Plan proposed a single, long (-2,100 feet) cul-de-sac to service this entire subdivision. The Applicant has continued to refine the Preliminary Plat in response to both Staff and the Planning Commission's concerns with that original configuration. Staff met internally to review the potential of utilizing a portion of Fire Station #1 to accommodate a second access into the subdivision. However, due to the location of the septic system, geothermal wells, and a planned future expansion to the building, it was determined that this is not a viable option. The Applicant has provided an updated Site Plan that now includes a second access from Armstrong Boulevard. City Staff sent this to Anoka County Highway staff for feedback. The second access does not meet current spacing guidelines for a County Highway; however, Anoka County Highway staff acknowledged the City's concerns about a single point of access serving this many homes and have noted they think a solution can be found. They did state that any potential second access would need to be a right in, right out only, must include a triangular, raised concrete median (pork chop) to reinforce the right in, right out access, and would also require a right turn lane for southbound traffic on Armstrong Boulevard. While Anoka County Highway has not provided formal approval, they are continuing to work with the City to find a safe solution. Formal approval of the Preliminary Plat would need to be contingent upon, among other things, County approval of a second access onto Armstrong Boulevard. Currently, the east -west road providing the second access to Armstrong Boulevard is proposed as a private street. Staff from multiple departments have indicated a preference for this to be a public street so that parking restrictions can be properly enforced and the street can be kept clear of snow and ice. This will likely impact road width and possibly the building configurations. Density Transitioning North and west of the Subject Property are existing residential lots zoned R-1 Residential (Rural Developing). Thus, regardless of the outcome of the requested Zoning Amendment, density transitioning is required along the common boundary line with the adjacent, impacted uses (the density transitionmg ordinance does not differentiate between 80 foot wide lots and 65 foot wide lots, it's just based on whether they're in the MUSA or not). While there are multiple options to satisfy density transitioning, the Applicant is proposing to utilize landscaping to achieve compliance. Per City Code Section 117-110 (Residential Development Transitioning), if landscaping is utilized, one of the following two options must be implemented: e Vegetative Buffer "C" - a minimum 45 feet in width in common ownership with the following planting schedule per 100
