Summary
Bell County requires new subdivision roads and drainage ditches to be at least 70 percent grassed over before the County accepts them for maintenance, per Subdivision Regulations § 206.7. Drainage ditches or culverts that silt up from erosion are treated as faulty construction, and the developer pays for repairs and stays on the hook until the ground stabilizes.
Drainage ditches or culverts that “silt up” or become filled with eroded materials will be considered faulty in design or construction and all repairs needed to return these facilities to design profile or grades will be at the expense of the Subdivider. All ditches and rights of way will be substantially (70%) grassed over prior to the County's acceptance of same for maintenance. (Note: If the right of way and included drainage ditches have not grassed over within the one-year warranty period, the warranty period will be extended to when erosion has ceased.)

Full Breakdown
7 of the Bell County Subdivision Regulations governs erosion control during the two-year warranty period that follows road and drainage construction in a new subdivision. It requires all ditches and rights-of-way to be substantially grassed over, at least 70 percent, before the County will accept them for ongoing maintenance. The section treats any drainage ditch or culvert that silts up or fills with eroded material as a design or construction defect rather than routine wear, meaning the Subdivider, not Bell County, pays to restore the facility to its design profile and grade.
7 extends the warranty period until erosion has actually stopped, so the developer's maintenance obligation and bonding exposure keep running past the normal one year until the ground is stable. 7 grassing and erosion criteria are met.
Violations & Fines
Ditches or culverts that silt up from erosion before reaching 70 percent grass cover are treated as faulty construction under § 206.7, and Bell County can draw on the Subdivider's warranty bond, letter of credit, or cash deposit to pay for regrading and re-grassing. The Commissioners Court will withhold formal acceptance of the roads and drainage system for county maintenance until the erosion has stopped and the grass cover requirement is met.
