Common use of Calculating Total Project Density with a Density Bonus Clause in Contracts

Calculating Total Project Density with a Density Bonus. The formula for calculating base units, bonus units, and total project density is as follows: 1. Base units are calculated by subtracting the area of lakes, rivers, and perennial streams from the gross acreage and multiplying the difference by the maximum density allowed in the zone(s). Where there is more than one zone, total base units shall be the sum of each zone calculation. 2. Bonus units are calculated by multiplying the acreage of developable land set aside as open space by 1.5 times the density allowed in its existing or proposed zone(s). Where there is more than one zone, total bonus units shall be the sum of each zone calculation. Where the existing or proposed zone is Open Space (OS), the density bonus calculation shall be based on the maximum density allowed by the General Plan land use designation. 3. Fractions of base units and bonus units resulting from the calculations above shall be rounded down to the next whole number. 4. Total maximum project density is the sum of the total base units and total density bonus units.
