Land Use Designations
WEBSITE UNDER CONSTRUCTION Please come back on September 22 to read and comment on the draft plan. |
The land use map (available HERE) uses various colors and patterns to represent different land use designations. Each color or pattern represents a specific category and land use. The boundary lines between land use areas are shown as precisely as possible, and generally follow property lines, washes, and/or roads.
Each designation portrays how an area is expected to be developed. This includes the type of development, the number of homes that can be built (referred to as residential density), and the size of commercial buildings (known as commercial intensity).
Resident density and commercial building intensity depict how concentrated development can be on a site. Generally, higher density or intensity results in more infrastructure required to address traffic, sewer, and other impacts.
Residential Density
Residential density is the allowable range of dwelling units (or homes) per acre. It establishes the appropriate number of homes for residential development. Homes may be distributed evenly across a site, or lot sizes may be smaller and clustered together, depending on terrain or other environmental factors.
For example, below is a 100-acre property designated Rural Low Density (0.0 – 0.3 homes per acre). This density would allow a maximum of 30 homes on this property.
- Acreage of Property (100 acres) X Homes Per Acre (0.0 – 0.3) = 0 to 30 homes
The layout of these homes could be distributed evenly across the 100 acres on 3.3. acre lots (see Figure A, below), or the lot sizes may be smaller (see Figure B, below). Residential density ranges are used to align the development of an area with the anticipated population.
Commercial Intensity
Commercial building intensity is the maximum allowable floor-area ratio, or FAR. This is the ratio of total building square footage on a property relative to the property's square footage. This serves to establish the appropriate building size for future commercial development.
The images below show how buildings of one and two stories could be developed on a given lot with a FAR of 1.00. For example, on a 10,000 square foot lot, a FAR of 1.00 would allow 10,000 square feet of building floor area to be built, regardless of the number of stories.
- 10,000 building square footage: 10,000 property square footage = FAR 1:1 or 1.0
The building could be built with two stories of 5,000 square feet each, or one story of 10,000 square feet. If the same 10,000 square foot lot had a FAR of 0.50, then 5,000 square feet of floor area could be built. A FAR of 0.25 would allow 2,500 square feet.

Rural Low-Density Residential (RLDR) Development Type: Single-family homes on large lots Residential Density: 0.0-0.3 dwelling units per acre | |
A Rural Low-Density Residential land use designation represents areas where single-family homes on large lots are intended. The lot sizes in this land use designation allow for substantial space between individual homes to maintain a rural character and retain the natural environment. Homes in this land use designation can range up to 0.3 dwelling units per acre (DU/AC), an average number of homes per acre. Click on the drop-down menu below to see an example. |
Rural Low-Density Residential Example
A development 100 acres in size may have a maximum of 30 homes.
- Property size: 100 acres
- Allowed average number of homes per acre: 0.0 to 0.3 DU/AC
- Range of homes: 0 to 30 homes
The development may have homes spread evenly across the 100 acres on larger lots, or it may have the same number of homes on smaller lots that retain additional open space. Both layouts would have the same average number of homes per acre.
Low-Density Residential-1 (LDR-1) Development Type: Single-family homes on large lots Residential Density: 0.04 - 1.2 dwelling units per acre | |
A Low-Density Residential-1 land use designation represents areas where single-family homes are appropriate, but only when it allows the retention of a rural, open character. The lot sizes in this land use designation allow for space between individual homes. The areas to be disturbed during construction should be clearly indicated on individual lots to ensure a minimum level of disturbance. Homes in this land use designation can range from 0.4 to 1.2 dwelling units per acre (DU/AC), the average number of homes per acre. Click on the drop-down menu below to see an example. |
Low-Density Residential -1 Example
A development of 100 acres in size may have 40 to 120 homes.
- Property size: 100 acres
- Allowed average number of homes per acre: 0.4 to 1.2 DU/AC
- Range of homes: 40 to 120 homes
The development may have homes spread evenly across the 100 acres on larger lots, or it may have the same number of homes on smaller lots that retain additional open space. Both layouts would have the same average number of homes per acre.
Low-Density Residential-2 (LDR-2) Development Type: Single-family homes on large lots Residential Density: 1.3-2.0 dwelling units per acre | |
A Low-Density Residential-2 land use designation represents areas where single-family homes are appropriate, but only when it allows retention of a rural, open character. The lot sizes in this land use designation allow for space between individual homes. The areas to be disturbed during development should be clearly indicated on individual lots to ensure a minimum level of disturbance. Homes in this land use designation can range from 1.3 to 2.0 dwelling units per acre (DU/AC), an average number of homes per acre. Click on the drop-down menu below to see an example. |
Low-Density Residential-2 Example
A development 100 acres in size may have 130 to 200 homes.
- Property size: 100 acres
- Allowed average number of homes per acre: 1.3 to 2.0 DU/AC
- Range of homes: 130 to 200 homes
The development may have homes spread evenly across the 100 acres on larger lots, or it may have the same number of homes on smaller lots that retain additional open space. Both layouts would have the same average number of homes per acre.
Medium-Density Residential (MDR) Development Type: Single-family homes, townhomes, or patio homes Residential Density: 2.1-5.0 dwelling units per acre | |
A Medium Density Residential land use designation represents areas where single-family homes, townhouses, or patio homes are appropriate. The lot sizes in this land use designation allow for space between individual homes (detached) or common walls between individual homes (attached). These areas should be located close to schools, shopping, and employment. Homes in this land use designation can range from 2.1 to 5.0 dwelling units per acre (DU/AC), an average number of homes per acre. Click on the drop-down menu below to see an example. |
Medium-Density Residential Example
A development 100 acres in size may have 210 to 500 homes.
- Property size: 100 acres
- Allowed average number of homes per acre: 2.1-5.0 DU/AC
- Range of homes: 210 to 500 homes
The development may have homes spread evenly across the 100 acres on larger lots, or it may have the same number of homes on smaller lots that retain additional open space. Both layouts would have the same average number of homes per acre.
