Best Practice Action 7.2

GreenStep City Best Practices: Land Use
Resilient City Growth No. 7

Increase financial and environmental sustainability by enabling and encouraging walkable housing and retail land use.

Best Practice Action 2

Achieve higher density housing through at least two of the following strategies:

a. Incorporate a flexible lot size/frontage requirement for infill development.
b. Use density and floor area ratio (FAR) bonuses in selected residential zoning districts.
c. Clustered residential development; tie a regulatory standard to comprehensive plan language defining compact city expansion zones that limit low-density development.
d. Allowing accessory dwelling units, single-room occupancy housing, senior housing, co-housing or tiny houses / apartments by right in selected zoning districts.

  • Here is one way a 500-acre urban walkshed -- the circle area accessible to the average person walking 10 minutues (1/2 mile) -- can evolve over time from an average density of 10 dwelling units per acre (DUA) to 30 DUA. (1) Add just 2 DUA (2 backyard cottages on each block) to 80% (400 acres) of the walkshed. (2) Take only 40 acres and develop a high property tax-generating, people-focused core of 180 DUA (6- and 8-story mixed-use buildings). (3) Surround the core with a belt of blocks (60 acres) at 60 DUA (a mix of townhouses, cottages, and small condos). From Carbon Zero cities (Alex Steffen: 2012 - search for "tentpole density").
  • Unlocking Home: Three Keys to Affordable Communities focuses on accessory dwelling units, rooming/boarding houses, and uncapping the number of roommates who may share a dwelling. Another density strategy is to lower the residential zoning requirement for minimum square feet per dwelling unit; Minneapolis dropped theirs to 390. The American Tiny Home Association has published guidelines for tiny home builders, which could be viewed as a model set of regulations for municipalities. View the 1-hour Regulatory Implications of Tiny Homes (Planetizen: 2017), a 1 AICP CM credit-approved online course. A related resource from 2013 is Policies for Shareable Cities: A Sharing Economy Policy Primer for Urban Leaders. A Shareable Cities resolution of support was adopted by the US Conference of Mayors in 2013.
  • See a national resource on accessory dwelling units, a Strong Town guide to making ADU's legal and easy, the Ventura Village (Minneapolis) carriage housing initiative, and background on cohousing, a specific residential building form, and also a type of intentional community. Defining characteristics include private homes for all ages supplemented by common facilities, and resident participation and management.
  • Note that short-term rentals on platforms such as AirBnB and VRBO (Vacation Rental By Owner), while adding lodging options, income and vitality to neighborhoods, can have negative impacts. Cities may need common sense rules to protect true home-sharers while reining in commercial operators who can reduce affordable housing options (2019 Harvard Business Review study) and diminish the quality of life in residential neighborhoods.
  • Missing Middle housing includes a variety of building types: duplexes, triplexes, courtyard apartments, bungalow courts, carriage houses, work/live units, townhouses and more.
  • See also implementation tools for action 7.1
1 star Use a process/ordinance (planned unit development or other) that allows increased density, and approves development on substandard lots through flexible frontage and lot sizes; create a density bonus in one residential or commercial zoning district; allow accessory dwelling units in one single-family zoning district or overlay area.
2 star Have a rural residential cluster development ordinance/process; have a density bonus in multiple areas in the city; bonus for underground parking or EV charging or proximity to transit or multifamily playground space; allow accessory dwelling units and/or co-housing developments in multiple single-family districts; allow tiny houses (~400 sq. ft.) on small lots or small (~350 sq. ft.) apartments.
3 star Create an additional density bonus linked to a transfer of development rights program that protects agricultural or natural resource land on the fringe of the urban area; tie ADUs explicitly into a plan for increasing affordable housing and/or reducing homelessness; allow rooming or boarding houses or single-resident occupancy units; uncap the number of roommates who may share a dwelling unit.

The PUD district permits lot flexibility and would allow a density bonus of up to 25 percent for hte provision of affordable housing. The PUD district also permits desity transfer within a development to preserve natural features. The Bluff Creek Overlay District requires the use of density transfer for the preservation of primary creek corridor. The RLM district permits smaller lot sizes with the preservation of significant,natural, upland areas.

Please note that we are still in the process of implementing our comprehensive plan updates and that on the zoning map, the areas that show up as R3C  Regional Center Residential will be changed to MIX zoning in a couple of months. Also, there is an existing MIX district at Valley Ridge where the Dakota CDA/Presbyterian Homes Valley Ridge assisted care/memory care and independent living mixed use project is under construction. (The site is located SW of the intersection of CSAH 5 and Burnsville Parkway on land that was formerly Valley Ridge Shopping Center.

Implementation details:
The City of Mankato offers Floor Area Ratio bonuses within the Central Business District-Core and Central Business District-Fringe zoning districts. While primarily commercial, residential is allowed and encouraged above the ground floor through Conditional Use Permit process. Floor Area Ratio incentives utilized for several recent and forthcoming redevelopment projects have been critical to these and has brought an increased residential component to the downtown core and contributed to the mixed-use vitaility of the area.

We also utilize the Planned Unit Development process. A planned unit development is intended to encourage the efficient use of land and resources, to promote greater efficiency in public and utility services, and to encourage innovation in the planning and building of all types of development. A planned unit development may be approved by the City Council following a review and recommendation by the Planning Agency.
