Environmental Rules That Shape Civil Projects
Every civil project touches environmental rules: stormwater, wetlands, streams, floodplains and, on the coast, shoreline protections.
Agencies and thresholds differ by state, so identify them during due diligence.
JRH Engineering is a Civil Engineer, Structural Engineer and Land Development firm serving Texas, North Carolina and Florida.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
Rules That Apply in All Three States
Construction stormwater: sites disturbing 1 acre or more need permit coverage and a SWPPP
Wetlands and streams: impacts to waters of the United States may need U.S. Army Corps of Engineers Section 404 permits
Floodplains: local floodplain administrators enforce FEMA-based rules on fill and finished floors
Texas
Stormwater: TCEQ’s Construction General Permit covers sites disturbing 1 acre or more
Local rules: cities and counties set their own drainage and development standards, such as Houston’s Chapter 42 development ordinance and Austin’s watershed protections
Thresholds matter: some counties trigger detention pond and drainage review at small disturbance areas, so layout can change permitting
North Carolina
Erosion control: plans for more than 1 acre need approval under G.S. 113A-57, and NCG010000 covers construction stormwater
Post-construction stormwater: 15A NCAC 02H .1000 sets state rules
Coastal areas: the Coastal Area Management Act (CAMA) applies in 20 coastal counties, with development rules in designated Areas of Environmental Concern
Buffers: several river basins have protected stream buffers
Florida
Environmental Resource Permits: FDEP or a water management district issues ERPs covering stormwater, wetlands and surface waters
Updated stormwater rules: CS/SB 7040 (Chapter 2024-275) applies to ERP applications deemed complete after December 28, 2025, including nutrient treatment requirements
Construction stormwater: FDEP’s Construction Generic Permit covers sites disturbing 1 acre or more
Who Does What
JRH provides civil site design, drainage, detention ponds, grading and SWPPPs.
Wetland delineations, environmental assessments, Section 404 permits, CAMA permits and mitigation are by others.
Bringing those consultants in early lets the civil layout avoid constraints rather than redesign around them.
Project: FM 1485 Industrial Site Development, New Caney, TX
Industrial site development in New Caney, Montgomery County
Coordination with Montgomery County and TxDOT for site access
Read the full FM 1485 case study
Challenges
Montgomery County’s 15,000 SF site disturbance threshold would trigger detention pond design and drainage district review
TxDOT access had to be coordinated alongside the county permit
Objectives
Stay under the disturbance threshold.
Streamline permitting and coordinate TxDOT access.
Solutions JRH Engineering Provided
Civil engineering site layout treating the 15,000 SF threshold as the governing constraint
TxDOT coordination for site access
Results:
Detention pond design avoided
A simplified county permit
