The specific calculations are set forth in Government Code Section 65915(f).
Unit calculations do not need to be based on individual subdivisions or parcels. If the density bonus units are located separate from the restricted occupancy units, such project groups shall, unless otherwise authorized by the Town, be contiguous and shall be developed simultaneously with the development of the restricted occupancy units.

At the developer's cost, the Town may retain a consultant to review the financial report. (If the developer is a nonprofit organization, the Town Council may elect to pay the cost of the consultant.)
b. Findings required for denial. The Town shall grant the requested incentive or concession unless the Town makes a written finding based upon substantial evidence that the incentive or concession:
Is not required to provide for affordable housing costs or for rents to be set at the specified levels; or
Would have a specific adverse impact upon public health and safety or the physical environment, or on any property listed in the California Register of Historical Resources, and for which there is no feasible method to satisfactorily mitigate or avoid the impact without rendering the development unaffordable to low and moderate income households.
