Environmental Rules in Conroe, TX

If you live in Conroe or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Conroe has 4 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.

Stormwater Management

Conroe requires a city stormwater permit and an engineer-prepared stormwater quality plan before any construction disturbing one acre or more can begin. Illicit discharges into the storm drain system are separately banned citywide.

Key details: Permit trigger: 1+ acre disturbed. SWP3 threshold: 5+ acres, state/federal rule. Permit term: 1 year, auto-expires. Inspection interval: Every 14 days / after 0.5" rain. Criminal fine: Up to $2,000/day.

Section 26-203 makes any violation strictly liable, with criminal fines up to $2,000.00 per violation per day, plus a separate civil penalty of up to $1,000.00 per day under Local Government Code § 54.017 once the city proves the violator had notice and continued the violation. The city may also seek injunctive relief through the city attorney. Orders can be appealed in writing to city council within ten working days.

This is one of the stricter rules in Conroe's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Flood Elevation Requirements

New residential construction and substantial improvements in Conroe's FEMA special flood hazard areas must elevate the lowest floor, including any basement, to at least one foot above the base flood elevation, certified by a licensed engineer, architect, or surveyor before the floodplain administrator issues a permit.

Key details: Freeboard required: One foot above BFE. Governing section: Code sec. 78-82(1). Permit: Floodplain development permit. Administrator: Director of Infrastructure Services. Penalty: Up to $500 per violation.

Building without full compliance is a misdemeanor. Each violation draws a fine of up to $500, plus all case costs, and the city council may pursue additional lawful action to remedy the noncompliant structure.

Erosion Control

Conroe requires grading and drainage permits for construction projects through the Engineering Department. Stormwater must not be redirected onto neighboring properties. Floodplain development requires additional permits.

Key details: Authority: Engineering Department. Permit Portal: OpenGov. Flood Zone Work: Requires floodplain permit. Drainage Impact: Cannot redirect onto neighbors.

Grading without permits subject to stop-work orders. Redirecting drainage onto neighbors may trigger nuisance citations up to $2,000.

Conroe is more permissive than most cities when it comes to erosion control. That said, there are still limits.

Flood Zones

Conroe requires a floodplain development permit before any construction, fill or alteration in a special flood hazard area, under Code of Ordinances section 78-38. The floodplain administrator reviews scaled plans showing structure elevation and location relative to the flood hazard area. Building without full compliance is a misdemeanor punishable by up to $500.00 per violation.

Key details: Permit required: Before any development in a special flood hazard area. Issuing official: City's floodplain administrator (infrastructure services director). Application form: Duplicate scaled plans showing elevations, per § 78-63. Appeals: Denials appealable to the appeal board. Maximum penalty: $500.00 fine per violation, misdemeanor.

Building, filling or substantially improving a structure in a special flood hazard area without first getting a floodplain development permit, or without following its conditions, is a misdemeanor under section 78-87, punishable by a fine of up to $500.00 for each violation plus court costs and expenses. The floodplain administrator can also deny or condition future permits, and appeals of a denial go to the appeal board rather than directly to court.

This is not one of those rules that cities tend to ignore. Conroe actively enforces its flood zones requirements.
