Download - Density Estimator for a Standard Subdivision (Rural District Only)

Density Estimator heading

This estimator will perform density calculations for a standard subdivision in accordance with Chapter 1 Section III of the Gorham Land Use and Development Code. Refer to the Gorham Land Use and Development Code for more specific information related to the Rural Zoning district, such as Space Standards, Permitted Uses, and Special Exceptions.

Step 1:

Density Estimator step 1After you have entered the project name (above), enter the Gross Lot Area for your parcel(s) in the cell to the right.
 

 

Step 2:

In the Rural Zoning district, Ordinance requires the deduction of land area unsuitable for development, rights-of-way and parking areas, significant wetlands, steep slopes, etc. from the gross lot area.

Density Estimator step 2In all events, the shape of the parcel boundary and space standards such as lot width, depth and setbacks, topography, and location will ultimately affect the resultant number of lots, which may be less than the estimated number of dwelling units.

 

Step 3:

Based on the data entered in steps 1 and 2, the estimator will calculate the total number of dwelling units allowed, per Ordinance, by dividing the net lot area by the minimum lot area per dwelling unit.

Density Estimator step 3The results are for design purposes only. The final number of dwelling units may be less than the estimated number due to the required the type of structure, shape of the lot, topography, internal and adjacent streets, etc.

The ‘Type of Structure’ portion of this estimator is interactive and is provided so that, during the design stage, a variety of combinations can quickly be considered. Once you know the maximum number of dwelling units allowed, you can determine the number of single-family, duplex, tri-plex and multi-family dwelling structures.

In the Rural Zoning district, individual lots may vary in size as long as the subdivision conforms to the overall net residential density of the parcel, and no lot for a single family dwelling unit is smaller than 40,000 square feet in area. See the Gorham Land Use Ordinance - Rural District for all related requirements.
