(a) Except as provided in subdivision (b), up to 10 percent of funds allocated for each program funded by this division may be expended, including, but not limited to, by grants, for planning and monitoring necessary for the successful design, selection, and implementation of the projects authorized under that program. This section shall not otherwise restrict funds ordinarily used by an agency for “preliminary plans,” “working drawings,” and “construction” as defined in the annual Budget Act for a capital outlay project or grant project. Planning may include feasibility studies for environmental site cleanup that would further the purpose of a project that is eligible for funding under this division.

(b) Funds used for planning projects that benefit disadvantaged communities may exceed 10 percent of the funds allocated if the state agency administering the moneys determines that there is a need for the additional funding.
