Front Setback 30 feet 25 feet L Side Setback rSide (Corner) Setback 1 r 5 feet 30 feet 10 feet 15 feet Rear Setback 30 feet l 30 feet I * If the density transitioning area is platted as an outlot (recommended by Staff), some of the lots would drop below the 0.25 acre threshold (lot sizes for six of the proposed lots would be 0.20 to 0.22 acres in size). 1 Does not appear to impact any lots (no corner lots proposed), but the standard should still be updated to reflect the actual requirement. The Planning Commission is conducting a Public Hearing on September 23, 2021, to consider a variance to lot size for the six (6) lots that, as a result of creating a separate outlot for the density transitioning area, would drop below the minimum lot area threshold. Staff will provide a verbal update to City Council regarding the outcome of that request. Attached Townhomes The table below outlines the proposed bulk standards and the minimum requirements for the R-2 Residential (Medium Density) District. Standard [_Setback from Private Road and Public Road Right -of -Way 7 Setback from Exterior Development Boundary Building to Building Setback R-2 Residential (Medium Density) 25 feet 30 feet 20 feet Proposed 25 feet 30 feet 25 feet Streets and Access The original Sketch Plan proposed a single, long (-2,100 feet) cul-de-sac to service this entire subdivision. Based on feedback from Staff and the Planning Commission, the Applicant revised the layout to eliminate the cul-de-sac and incorporate a second access onto Armstrong Boulevard. The proposed 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 and 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. The plan set has been forwarded to the Anoka County Highway Department, but as of the writing of this case, no response has been received. 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 should to be contingent upon, among other things, County approval of a second access onto Armstrong Boulevard. The east -west road providing the second access to Armstrong Boulevard is proposed as a private street. Public Safety Staff prefer to see this as a public street, which would assist in enforcement of no overnight parking. The Applicant agreed to widen the street from twenty-four (24) feet to thirty (30) feet. However, they are opposed to providing the sixty (60) feet of right-of-way required for a public street as it would likely eliminate two (2) buildings (a total of 10 units). The current proposal is a thirty (30) foot wide private road that the Home Owners Association (HOA) would be responsible for maintenance and plowing. Density Transitioning North and west of the Subject Property are existing residential lots zoned R-1 Residential (Rural Developing). Thus, density transitioning is required along the common boundary line with the adjacent, impacted uses. 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: • Vegetative Buffer "C" - a minimum 45 feet in width in common ownership with the following planting schedule per 100 feet of property boundary adjacent to impacted use: • 8 overstory trees • 8 evergreen trees • 8 understory trees • Vegetative Buffer "B" with a berm - a minimum 35 feet in width in common ownership with the following planting
