Summary

Richardson's tree code sets a higher protection tier for its biggest trees: any tree with a caliper of 24 inches DBH or more is a "specimen tree," and removing one requires replanting at double the ratio required for an ordinary protected tree. Developed single-family and duplex residential lots are exempt.

Protected tree means any tree six inches in caliper DBH or larger which is not an unprotected tree. ... Specimen tree means a tree with a caliper of 24-inches DBH or greater. ... Replacement of each protected tree shall require the replanting of replacement trees of not less than one caliper inch DBH for each one caliper inch DBH of removed tree. Replacement of each specimen tree shall require the replanting of replacement trees of two caliper inches DBH for each one caliper inch DBH of removed tree. Replacement trees shall be not less than three caliper inches DBH and not less than 14 feet tall measured from the top of the root ball at the time of planting.

Full Breakdown

5, adopted by Ord. No. 4496 on May 6, 2024, splits trees into two protected tiers. A "protected tree" is any tree six inches in caliper DBH or larger; a "specimen tree" is a tree with a caliper of 24 inches DBH or greater, the code's marker for its most mature and significant trees. 5-7(c) doubles that to 2:1 for a specimen tree. 5-7(d). Owners can instead pay into the city's tree management fund at a rate set in the Master Fee Schedule per caliper inch of required mitigation, rather than replanting on site.

5-2(a) exempts trees removed from a developed residential property or in connection with residential redevelopment, so a homeowner replacing a mature oak in their own yard is not subject to the specimen-tree mitigation ratio.

Violations & Fines

Removing a specimen tree without the required permit exposes the owner to the same penalty as any unpermitted protected-tree removal under section 22.5-6(a): a fine of up to $2,000.00 per tree, with each tree a separate offense. The development services director, city building official or another authorized representative can place a stop-work order on activity that is removing protected or specimen trees in violation of chapter 22.5, and a director's interpretation can be appealed to the board of adjustment under section 22.5-4(b).

Frequently Asked Questions

What makes a tree a "specimen tree" in Richardson?
Caliper size. Section 22.5-3 defines a specimen tree as one with a caliper of 24 inches DBH or greater, distinct from an ordinary protected tree, which is any tree six inches DBH or larger.
Do I have to replace a specimen tree at a higher rate than a smaller protected tree?
Yes. Section 22.5-7(c) requires two caliper inches of replacement tree for every caliper inch of a removed specimen tree, double the 1:1 ratio that applies to a standard protected tree under section 22.5-7(b).
Does this apply if I want to remove a big tree in my own backyard?
No. Section 22.5-2(a) exempts trees removed from a developed residential property, or in connection with residential redevelopment, from the entire tree protection article, including the specimen-tree mitigation ratio.
How big does the replacement tree have to be?
At least three caliper inches DBH and 14 feet tall at planting, measured from the top of the root ball, under section 22.5-7(d), regardless of which tier is being replaced.
