Montgomery County enforces stormwater management under its MS4 permit with TCEQ. Post-Harvey 2017 rules increased detention and floodplain standards. Conroe and The Woodlands have strict drainage criteria for development.
Montgomery County is a TCEQ-regulated Municipal Separate Storm Sewer System (MS4) operator under federal Clean Water Act authority. The county's drainage criteria manual requires detention for developments over 1 acre: typical standard is to detain the 100-year storm and release at pre-development rates. After Hurricane Harvey (2017), San Jacinto River Basin standards tightened β Conroe and The Woodlands require freeboard above 500-year flood elevations for critical facilities. Conroe Code Ch. 78 mandates stormwater plans for any site over 10,000 sq ft disturbed area. Woodlands Township coordinates with Montgomery County Engineer on regional detention. Lake Conroe dam operations by SJRA affect downstream drainage. Illicit discharges (paint wash, concrete slurry, oil) to storm drains prohibited under TCEQ TPDES permit and carry substantial penalties. Harvey Flood Mitigation Bond funded regional detention projects.
No-plan construction: stop-work order plus $250 to $2,000/day Conroe. Illicit storm drain discharge: TCEQ penalties up to $25,000/day. Detention maintenance failures: county notice, $100 to $1,000, abatement liens.
