Maintenance/Channel Projects

Jefferson County Drainage District No. 7 (The District) Projects (PAGE UNDER CONSTRUCTION)
As of March 1, 2026

Routine Maintenance:

Ditch Maintenance: crews maintain approximately 281 miles of earthen and concrete channels within DD7 boundaries from March until late November or early December. During the winter months, these crews cut back trees and brush encroaching on DD7 channels.
Herbicide Department: assist in maintaining drainage channels by applying herbicide to new growth in the concrete channels as well as applying herbicide to the earthen channels. The crew also repairs fencing and cable barriers throughout the district.
Pump Station Maintenance: Daily inspections and general maintenance and repairs to The Districts 20-pump stations. All stations are inspected daily including weekends and holidays.
Hurricane Levee Crew: Maintains and repairs the Districts 36 miles of earthen levee, concrete & steel sheet pile floodwall and closure structures throughout the levee system.

Maintenance & Operations Projects:

Non-District Channel: DD7 has agreed to remove trees and muck out a drainage channel outside of our district boundaries at Lamar Ave. & Twin City Hwy in Central Gardens. This channel drains a portion of Central Gardens and discharges into the Neches River.
HFPL: Repaired approximately 100’ section of levee at station 1314+00. The compromised section was removed and replaced with new material. The repair consisted of 8” lifts compacted to 6” with 3 successful compaction test per lift. Once the repairs were complete, the bare section of levee was hydro mulched to ensure proper vegetation growth.
