Traffic Impact Fee (TIF) Offset Program for Affordable Housing

The Board of Supervisors has long recognized that high traffic impact fees, while appropriate to address traffic impacts from development, have a negative effect on efforts to develop housing affordable for lower income households. The Traffic Impact Fee Offset Program for Developments with Affordable Housing Units (Board Policy B-14(PDF, 56KB)) includes a provision to set aside one million of federal and state transportation revenues annually, for a period of twenty (20) years, to be used to offset Traffic Impact fees in the development of affordable housing. The Traffic Impact Fee (TIF) Offset Program allows for a reduction of traffic impact fees and is not a cash subsidy. Only income restricted units are eligible for the offset. A housing development project of more than five (5) units where at least twenty (20) percent of the units will be affordable to very low-, low-, or moderate-income households, or accessory-dwelling units targeted to the aforementioned income group(s), on owner occupied property, may be eligible for Traffic Impact fee offset under specific program guidelines(PDF, 517KB).
