Grapevine's Environmental Rules: The Rules That Matter
If you live in Grapevine or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Grapevine has 4 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.
Flood Zones
Portions of Grapevine lie within FEMA-designated Special Flood Hazard Areas around Grapevine Lake, Denton Creek, Silver Lake Creek, and Big Bear Creek. The city participates in the NFIP and Community Rating System. New construction in the 1-percent-annual-chance floodplain must have the lowest floor elevated at least 1 foot above base flood elevation.
Key details: NFIP Participation: Yes, with CRS discounts. Freeboard: 1 foot above BFE required. Substantial Improvement: Over 50 percent of value. Mapped Waterways: Grapevine Lake, Denton Creek. Floodplain Admin: (817) 410-3154.
Contact your local code enforcement office for specific penalty information.
Compared to other cities, Grapevine takes a harder line on flood zones. The enforcement and penalty structure reflects that.
Grading & Drainage
Grapevine requires grading and drainage to direct stormwater away from structures and not impose runoff onto adjacent properties. A grading plan is required for new construction, substantial additions, and any earthwork that alters drainage patterns. Pools, retaining walls, and landscaping cannot redirect water onto neighbors or block drainage easements.
Key details: Foundation Slope: 6 inches in 10 feet minimum. Grading Plan: Required for new construction. Easements: Cannot be filled or blocked. Retaining Walls: Over 4 feet need engineering. Engineering: (817) 410-3138.
Contact your local code enforcement office for specific penalty information.
This is one of the stricter rules in Grapevine's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Stormwater Management
Grapevine operates an MS4 (Municipal Separate Storm Sewer System) under a TPDES permit from the Texas Commission on Environmental Quality. Property owners must not discharge pollutants into storm drains. Construction sites over 1 acre require SWPPP (Stormwater Pollution Prevention Plans). Illicit discharges carry fines up to $500 per day.
Key details: Permit: TPDES Phase II MS4. SWPPP Trigger: 1 acre or larger disturbance. Prohibited: Paint, concrete, oil, yard waste. Receiving Waters: Grapevine Lake, Denton Creek. Report Discharges: (817) 410-3330.
Contact your local code enforcement office for specific penalty information.
This is not one of those rules that cities tend to ignore. Grapevine actively enforces its stormwater management requirements.
Erosion Control
Grapevine requires erosion and sediment control measures on all construction and land-disturbing activities to prevent sediment from entering streets, storm drains, and waterways. Silt fencing, inlet protection, and stabilized construction entrances are required before grading begins. Violations can trigger stop-work orders and fines up to $500 per day.
Key details: Required BMPs: Silt fence, inlet protection, stone entrance. Installation Timing: Before grading begins. SWPPP Threshold: 1 acre disturbance. Street Cleanup: Same-day required. Inspections: Public Works site visits.
