Summary

When work in a Harris County Flood Control District right-of-way removes a 'desirable' tree, the ROW user must replace it inch for inch with the same or a similar species. Ch. 41, Subchapter 41B, Sec 25 sets this ratio separately from the county's specimen-tree caliper formula used in road right-of-way.

City-specific rules exist: Houston has its own protected tree species rules that differ from Harris County's county-level regulations. If you live in Houston, check the city-specific page instead.

HCFCD may require a ROW user to provide Landscaping plans sealed by a Registered Landscape Architect licensed in the State of Texas detailing any vegetation management activities proposed with HCFCD ROW when the ROW User's work in the ROW will involve removal of trees. ... Tree Removal Provide a tree replacement plan for all desirable trees designated to be removed. Tree replacement will be inch for inch of the same or similar species.

Full Breakdown

Harris County splits its tree-replacement math by which agency controls the right-of-way. For work inside a county road right-of-way, Ch. 41, Subchapter 41B, Sec 25 ties replacement to specimen trees of 12 inches caliper and larger, requiring enough three-inch-caliper replacements to match the removed tree's total caliper. For work inside Harris County Flood Control District (HCFCD) right-of-way, the same section sets a different, simpler standard: HCFCD can require the ROW User to submit landscaping plans sealed by a Texas-licensed Registered Landscape Architect detailing any vegetation management the work will involve whenever tree removal is part of the job.

Those plans must show trees marked for preservation, protected with 'tree protection zones' installed before construction starts, and detailed on the landscape drawings with the protection method noted on a detail sheet. For trees actually designated for removal, the plan must replace 'desirable' trees inch for inch of the same or a similar species, a one-to-one diameter match rather than the road right-of-way's caliper-totaling formula. Pruning tied to the same HCFCD vegetation management work is restricted to licensed and bonded Texas tree care professionals, capped at removing no more than one-quarter of a tree's canopy for access, and must follow ANSI A300 pruning practices.

The distinction matters because a project can straddle both a county road easement and an adjoining HCFCD channel easement, and the applicable replacement ratio depends on which right-of-way holds the tree being removed.

Violations & Fines

Sec 31 makes noncompliance with any Vegetation Management requirement, including the HCFCD replacement-plan and inch-for-inch replacement mandate, a violation of these Rules. That is a Class C misdemeanor the County Engineer or HCTRA Executive Director can pursue in Justice of the Peace Court, with the County Engineer able to refer a case to the County Attorney for injunctive relief or a civil penalty against the ROW User.

Frequently Asked Questions

Is the HCFCD replacement ratio the same as the county road ratio?
No. Road right-of-way removals of 12-inch-plus specimen trees use a caliper-totaling formula with three-inch minimum replacements. HCFCD right-of-way removals of desirable trees instead use an inch-for-inch replacement of the same or a similar species, under the same Ch. 41, Subchapter 41B, Sec 25.
Who has to seal the HCFCD landscaping plan?
A Registered Landscape Architect licensed in the State of Texas must seal the landscaping plan whenever HCFCD requires one for vegetation management work involving tree removal. The plan also has to show which trees are being preserved and how they are protected during construction.
How much of a tree can be pruned for access?
No more than one-quarter of the tree's canopy, and only by a Texas-licensed and bonded tree care professional following ANSI A300 pruning practices, whether the work is inside county road or HCFCD right-of-way. Pruning beyond that limit is treated as removal for replacement purposes.
