Requirements

Projects in transit corridors

For projects with existing and/or planned transit service (i.e., service with the funding commitments specified in SLL Prerequisite 1, Smart Location) that meets or exceeds the 2-point threshold in SLL Credit 3, Locations with Reduced Automobile Dependence, Option 1, build at the following densities, based on the walk distances to the transit service specified in SLL Credit 3:

  1. For residential components located within the walk distances: 12 or more dwelling units per acre (30 DU/hectare) of buildable land available for residential uses.
  2. For residential components falling outside the walk distances: 7 or more dwelling units per acre (17.5 DU/hectare) of buildable land available for residential uses.
  3. For nonresidential components located within the walk distances: 0.80 floor-area ratio (FAR) or greater of buildable land available for nonresidential uses.
  4. For nonresidential components falling outside the walk distances: 0.50 FAR or greater of buildable land available for nonresidential uses.
    1. If the project location is served by a transit agency that has specified guidelines for minimum service densities that are greater than the densities required by this prerequisite, the project must achieve those service densities instead.

      OR

      Option 2. All other projects

      Build any residential components of the project at a density of 7 dwelling units per acre (17.5 DU/hectare) of buildable land available for residential uses.

      AND

      Build any nonresidential components of the project at a density of 0.50 FAR or greater of buildable land available for nonresidential uses.

      For all projects

      Density calculations include all planned and existing buildings within the project boundary, excluding those portions of parking structures devoted exclusively to parking.

      The specified density must be achieved within five years of the date that the first building of any type is occupied.

      If one component of the project, residential or nonresidential, meets the minimum density requirement but the other component does not, include only the qualifying density. Use that component’s dwelling units or nonresidential floor area in the numerator and the total buildable land area in the denominator. If the resulting density meets the minimum requirement, the prerequisite is achieved.

      Design and build the project such that residential and nonresidential components achieve the densities per acre (hectare) of buildable land listed in Table 1 (excluding those portions of parking structures devoted to parking).

      Table 1. Points for density per acre (hectare) of buildable land

      Residential density (DU/acre) Residential density (DU/hectare) Nonresidential density (FAR) Points
      > 10 and ≤ 13 > 25 and ≤ 32 > 0.75 and ≤ 1.0 1
      > 13 and ≤ 18 > 32 and ≤ 45 > 1.0 and ≤ 1.25 2
      > 18 and ≤ 25 > 45 and ≤ 62 > 1.25 and ≤ 1.75 3
      > 25 and ≤ 38 > 62 and ≤ 94 > 1.75 and ≤ 2.25 4
      > 38 and ≤ 63 > 94 and ≤ 156 > 2.25 and ≤ 3.0 5
      > 63 > 156 > 3.0 6
      DU = dwelling unit; FAR = floor-area ratio.

      The specified densities must be achieved within five years of the date that the first building of any type is occupied.

      The scoring of a mixed-use project is calculated with a weighted average, according to the following steps.

      1. Determine the total floor area of all residential and nonresidential uses.
      2. Calculate the percentage residential and percentage nonresidential of the total floor area.
      3. Determine the density of each component as measured in dwelling units per acre (hectare) and floor-area ratio, respectively.
      4. Referring to Table 1, find the appropriate points for the densities of the residential and nonresidential components.
      5. If the points are different, multiply the point value of the residential component by its percentage of the total floor area and multiply the point value of the nonresidential component by its percentage.
      6. Add the two scores.
        Option 1: Development density

        Construct or renovate a building on a previously developed site AND in a community with a minimum density of 60,000 square feet per acre net (13,800 square meters per hectare net). The density calculation is based on a typical two-story downtown development and must include the area of the project being built.

        OR

        Option 2: Community connectivity

        Construct or renovate a building on a site that meets the following criteria:

        • Is within 1/2 mile of at least 10 basic services
        • Has pedestrian access between the building and the services

        For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public. No more than 2 of the 10 services required may be anticipated (i.e. at least 8 must be existing and operational). In addition, the anticipated services must demonstrate that they will be operational in the locations indicated within 1 year of occupation of the applicant project.

        Case 1. Projects with access to quality transit

        For projects with existing or planned transit service (i.e., service with the funding commitments as specified in SLL Prerequisite Smart Location) that meets or exceeds the 2-point threshold in SLLc3 Access to Quality Transit Option 1, build at the following densities, based on the walking distances to the transit service specified in that SLL credit:

        • for residential components located within the walking distances: 12 or more dwelling units per acre (30 DU per hectare) of buildable land available for residential uses;
        • for residential components falling outside the walking distances: 7 or more dwelling units per acre (17.5 DU per hectare) of buildable land available for residential uses;
        • for nonresidential components located within the walking distances: 0.80 or higher floor-area ratio (FAR) for the buildable land available for nonresidential uses; and
        • for nonresidential components falling outside the walking distances: 0.50 or higher FAR for the buildable land available for nonresidential uses.

        If the project location is served by a transit agency whose guidelines for minimum service densities are greater than the densities required by this prerequisite, the project must achieve those service densities instead.

        Case 2. All other projects

        Build any residential components of the project at a density of 7 or more dwelling units per acre (17.5 DU per hectare) of buildable land available for residential uses.

        Build any nonresidential components of the project at a density of 0.50 or higher FAR for the buildable land available for nonresidential uses.

        Option 1. Surrounding density

        Locate on a previously developed site whose density in the surrounding area (i.e., within a ¼-mile [400-meter] radius of the project boundary) meets or exceeds the values in Table 1. Projects may calculate surrounding density using either the “separate residential and nonresidential densities” or the “combined density” values.

        If the surrounding residential and nonresidential densities are of different point values, use a weighted average of the two.

        Physical education spaces that are part of the project site, such as playing fields and associated buildings used during sporting events only (e.g., concession stands) and playgrounds with play equipment, are excluded from the development density calculations.

        Option 1. Development and adjacency (2–3 points)

        Construct or renovate the project on a previously developed site (2 points).
        OR
        Construct or renovate the project on a site that is both previously developed and adjacent site. The adjacent sites must be currently used for industrial or commercial purposes (3 points).

        Option 1. Development density (1 point)

        Locate on a previously developed site whose average surrounding density (i.e., within a ¼-mile [400-meter] radius of the project boundary) is

        • At least 7 dwelling units per acre (17.5 DU per hectare) with a 0.5 floor-area ratio, or
        • At least 22,000 square feet per acre (5,050 square meters per hectare) of buildable land.
        • The calculated density must be existing density, not zoned density.

          For previously developed existing rural healthcare campus sites, achieve a minimum on-site development density of 30,000 square feet per acre (6890 square meters per hectare).

          Design and build the project such that residential and nonresidential components achieve the densities per acre/hectare of buildable land listed in Table 1 at build-out or within five years of the date that the first new building of any type is occupied (excluding those portions of parking structures devoted to parking), whichever is lower.

          DU = dwelling unit; FAR = floor-area ratio.

          The scoring of a mixed-use project is calculated with a weighted average, according to the following steps.

          1. Determine the total floor area of all residential and nonresidential uses.
          2. Calculate the percentage residential and percentage nonresidential of the total floor area.
          3. Determine the density of each component as measured in dwelling units per acre or hectare and floor-area ratio, respectively.
          4. Referring to Table 1, find the appropriate points for the densities of the residential and nonresidential components.
          5. If the points are different, multiply the point value of the residential component by its percentage of the total floor area and multiply the point value of the nonresidential component by its percentage.
          6. Add the two scores.
          7. Design and build the project to meet the densities specified below. Minimum densities must be met for both (1) the entire project at full build-out and (2) the portion of the project that will be built within five years of the date that the first new building of any type is occupied.

            Case 1. Projects with access to quality transit

            For projects with existing or planned transit service (i.e., service with the funding commitments as specified in SLL Prerequisite Smart Location) that meets or exceeds the 2-point threshold in SLLc3 Access to Quality Transit Option 1, build at the following densities, based on the walking distances to the transit service specified in that SLL credit:

            • for residential components located within the walking distances: 12 or more dwelling units per acre (30 DU per hectare) of buildable land available for residential uses;
            • for residential components falling outside the walking distances: 7 or more dwelling units per acre (17.5 DU per hectare) of buildable land available for residential uses;
            • for nonresidential components located within the walking distances: 0.80 or higher floor-area ratio (FAR) for the buildable land available for nonresidential uses; and
            • for nonresidential components falling outside the walking distances: 0.50 or higher FAR for the buildable land available for nonresidential uses.

            If the project location is served by a transit agency whose guidelines for minimum service densities are greater than the densities required by this prerequisite, the project must achieve those service densities instead.

            Case 2. All other projects

            Build any residential components of the project at a density of 7 or more dwelling units per acre (17.5 DU per hectare) of buildable land available for residential uses.

            Build any nonresidential components of the project at a density of 0.50 or higher FAR for the buildable land available for nonresidential uses.

            For all projects

            Density calculations include all planned and existing buildings within the project boundary, excluding those portions of parking structures devoted exclusively to parking.

            If the residential component of the project meets the minimum density requirement but the nonresidential component does not, or vice versa, include only the qualifying density. Use that component’s dwelling units or nonresidential floor area in the numerator and the total buildable land area in the denominator. If the resulting density meets the minimum requirement, the prerequisite is achieved.

            Design and build the project such that residential and nonresidential components achieve the densities per acre/hectare of buildable land listed in Table 1 at build-out or within five years of the date that the first new building of any type is occupied (excluding those portions of parking structures devoted to parking), whichever is lower.

              Proximity is determined by drawing a 1/2-mile radius (800-meter) around a main building entrance on a site map and counting the services within that radius.

              Option 1: Development density

              Construct or renovate a building on a previously developed site AND in a community with a minimum density of 60,000 square feet per acre net (13,800 square meters per hectare net). The density calculation is based on a typical two-story downtown development and must include the area of the project being built.

              OR

              Option 2: Community connectivity

              Construct or renovate a building on a site that meets the following criteria:

              • Is located on a previously developed site
              • Is within 1/2 mile of a residential area or neighborhood with an average density of 10 units per acre net
              • Is within 1/2 mile of at least 10 basic services
              • Has pedestrian access between the building and the services

              For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public. No more than 2 of the 10 services required may be anticipated (i.e. at least 8 must be existing and operational). In addition, the anticipated services must demonstrate that they will be operational in the locations indicated within 1 year of occupation of the applicant project. Examples of basic services include the following:

              • Bank
              • Place of Worship
              • Convenience Grocery
              • Day Care Center
              • Cleaners
              • Fire Station
              • Beauty Salon
              • Hardware
              • Laundry
