Application process
Typical processing: TCEQ states the OSSF permitting authority must approve or deny OSSF planning materials and permit applications within 30 days of receipt.
- 01 Determine whether the parcel is unincorporated Lamar County and not within city limits.
- 02 For access work, obtain the county culvert permit if a driveway culvert or related county-road crossing is involved.
- 03 For subdivision or development creating lots or plats, follow county development notices and county clerk plat-filing requirements.
- 04 For OSSF or septic work, verify the local permitting authority through TCEQ OARS; TCEQ states permits are required to construct, install, alter, extend, or repair an OSSF unless a narrow exemption applies.
- 05 If the parcel is in a flood-risk area, verify whether any floodplain approval is required. Lamar County HMAP materials state the county itself does not participate in NFIP.
