A. Purpose
This Section provides a uniform method for calculating the ratio.

B. Applicability
The FAR dimensional standard applies to residential and nonresidential in the Environs Zone. The maximum permitted FARs are identified in Section 5.6. The calculations are as follows:
C. Measurement
1. General
a. FARs are used in conjunction with , requirements, and limitations to determine and define the bulk that may occur on a given .
b. The FAR provides the maximum amount of that can be developed on a . However, the maximum permitted FAR is based on the most favorable situation and may not be achievable due to other and dimensional .
c. The may be divided into any number of , principal , and provided the combined square footage does not exceed the permitted of the .
2. Calculation
a. Multiply the area of the , expressed in square feet, by the applicable FAR. The result is the maximum amount of permitted on the . See Figure 6.4.6-A for an example of the FAR calculation.
b. See the definition of " " (Section 11.4.8) and exception provided below for the types of improvements and that are and are not included in the FAR calculation.

6.4.7 RESIDENTIAL
A. Purpose
This Section provides uniform methods for determining residential densities on individual .
B. Applicability
Residential for all residential projects is calculated as follows.
1. Residential in residential projects is based on one dwelling unit per minimum size by area, exclusive of any and drainageway dedications or exclusive use easements. Because the acreage of a used for and drainageway purposes differs for each , it is difficult to provide a simple calculation that would give an exact figure.
The following provide two methods of calculating approximate for a . The number of units obtained through these calculations is an estimate and can only be verified by the actual design of the . Should there be a need to express a ratio per , for comparison purposes only, such ratio will be calculated using the second method assuming 30 percent of the would be used for , drainageways, or other uses whose acreage is not included to calculate allowable .
a. The first method of calculation gives the highest possible that can be achieved on a . However, to achieve this , the following two design criteria must be present. (See Figure 6.4.7-A Residential , Method 1)
i. The property can be developed without additional dedications for , drainageways, or exclusive use easements.
ii. Each is the minimum size permitted by the underlying .
The , expressed in square feet, is divided by the minimum permitted by the underlying .


: 71,400 square feet (sf) or 1.64
Minimum : 7,000 sf
Approximate No. of Units = ÷ Minimum
= 71,400 sf ÷ 7,000 sf
= 10.2 units
= 10 units + .2 remainder
Approximate = Units ÷
= 10.2 units ÷ 1.64
= 6.22 dwelling units/
Figure 6.4.7-A Residential , Method 1
b. The second method assumes that the design requires dedication of either , drainageways, or exclusive use easements or will have other conditions that do not allow every square foot of the property to be included in an individual . Also, due to varying widths of and drainageway and configurations, it is impossible to an exact number of units or lots that can be achieved. Since the amount of used for , drainageways, etc., varies from to , it is necessary to approximate the amount of by percentage that will be needed for those purposes. It will be assumed, to illustrate the calculations, that 30 percent of the will be utilized for such purposes. (See Figure 6.4.7-B Residential , Method 2)
The calculation is the , expressed in square feet, minus 30 percent of the , divided by the minimum permitted by the underlying .


: 87,120 square feet (sf) or 2
Minimum : 7,000 sf
for streets, etc.: 26,136 sf (approximately 30%)
Approx. No. of Units = ( - 30% of ) ÷ Minimum
= (87,120 sf - 26,136 sf) ÷ 7,000 sf
= 8.71 units
= 8 units + .71 remainder
Approx. = Units ÷
= 8 units ÷ 2
= 4 dwelling units/
Figure 6.4.7-B Residential , Method 2
2. Residential in multifamily developed is calculated in the following manner.
a. Multiply the area of the , in acreage, by the (units per ratio) permitted by the underlying zoning.
Example:
Units Per Ratio: 15.0
: 6
Calculation:
Units per x = no. of units
15 x 6 = 90 units
b. Exception. Any or sold at to the City for public purposes is included as part of the for calculation of , provided:
i. The additional is less than 10 percent of the permissible for the rest of the ;
ii. Such dedication was not a condition of approval for applications, such as, but not limited to, or variance requests;
iii. Such dedication does not include as part of a ; and
iv. A legally binding agreement to or sell at to the City is submitted as part of the application.
3. Residential in Flexible is based on the (as defined in Section 11.4.5 Definitions - D) of the .
