The amount allocated to a transportation planning agency designated pursuant to Section 29532 of the Government Code, for the preparation or updating of a regional transportation plan pursuant to Chapter 2.5 (commencing with Section 65080) of Title 7 of that code, may be up to 70 percent of its nonfederally reimbursed costs for regional transportation planning.
For a transportation planning agency in a county with a population of less than 500,000 persons, the director may increase that percentage, if the director determines it to be in the best interests of regional and state transportation planning to do
so.
