Culvert and drainage work in Freeport, TX
Low ground near the Intracoastal Waterway means we plan for tidal push, not just rainfall.
Freeport drains differently than inland Brazoria County
Freeport sits at the mouth of the Brazos River and the Gulf Intracoastal Waterway, inside Zone 3 of Brazoria County Drainage District 5 alongside Quintana and Surfside Beach. Main roads through town run along Brazosport Boulevard (State Highway 288), FM 523 out toward the Velasco section, and Velasco Boulevard itself. Ground here sits low enough that drainage design has to account for tidal push and storm surge on top of ordinary rainfall, not just the flat clay drainage most of inland Brazoria County deals with.
Freeport is an incorporated city, so driveway culverts and drainage work on city streets go through Freeport's own public works office rather than Brazoria County Engineering. We confirm that jurisdiction before filing anything, since a ditch that looks the same on both sides of a city line can answer to two completely different offices.
Four jobs, same as everywhere else we run trucks
Driveway culvert install
New driveway crossing a city ditch or drainage swale. We confirm jurisdiction, then size the pipe accordingly. See the process →
Culvert replacement
Coastal humidity and salt air take a toll on older pipe faster than inland ground does. We pull and reset it to grade. See the process →
Ditch grading & drainage
Re-slope a silted city ditch, or address a yard low spot that has to fight tidal backpressure to drain. See the process →
Site pads
Compacted pad built up above the naturally low Freeport grade for a shop, shed, or driveway base. See the process →

City street or county road? We check both.
Freeport's city limits, the Velasco area, and the surrounding unincorporated county pockets all sit close together along Highway 288 and FM 523. We confirm which permit process applies to your specific address before we file. Read how city and county permits differ →
Freeport culvert and drainage questions
Does hurricane season change how you size a Freeport culvert?
Yes, in one specific way. We still size the pipe to the ditch's normal flow, but we also check the outlet for tidal backpressure so the culvert doesn't just back up on a high-tide day even with no rain falling.
Does the City of Freeport or the county handle my permit?
Inside city limits, Freeport's own public works office handles it. On a county-maintained road outside the city, it's Brazoria County Engineering. We check your exact address before filing either way.
Do you work in the Velasco area?
Yes. Velasco Boulevard and the streets around it are part of our regular Freeport coverage, same as the rest of the city along Brazosport Boulevard.
My ditch drains fine most of the year but backs up during storm season. Is that normal?
It's common in Freeport specifically. Low ground near the Intracoastal Waterway means a ditch that handles ordinary rain fine can still get pushed back during a surge event. We tell you honestly if that's a grading fix or something bigger.
