Most states don't allow local PDs to keep forfeiture proceeds from state-law forfeitures; the federal government allowed local jurisdictions involved in federal-law forfeitures to keep a large portion (80%) of the assets, but the standards for that program were made more restrictive a few years back, and it was suspended entirely last December (notionally, at least, as a cost saving measure), so right now there's really no way for a local PD to raise funds by way of forfeiture.
