- Most of the tree legislation I have seen is done
by municipalities, or in subidvision deed restrictions.
State legislatures are involved only to the point of
ENABLING municipalities and/or counties in that
level of regulation. Current work at the state level
in Texas is aimed at legislation giving counties the
power to regulate by ordinance. (Cities already
have the power.) Since most of the growth is taking
place outside of city limits, I am very much in favor
of that proposal.
The replacement verbage in landscape ordinances
usually refers to diameter inch: For a tree of 12" diameter
removed, a replacement of six 2" diameter trees would
be acceptable. Or twelve 1" trees. Obviously, this does
not replace the mature canopy but it's a start. San Diego
probably has the oldest, most detailed landscape
ordinance. Portland, OR also.
I have the name of a Tomball business that is developing
ways to transplant large trees economically, using heavy
one-of-a-kind equipment if any one is interested.
The Mayor of Houston is in the process of forming a
"Green Ribbon" committee to promote a tree ordinance for
Houston. Someone close to that activity in the Mayor's office
told me he favored going for a replacement requirement based
on AREA, not diameter. So (A=pi r squared) and that
12" tree would be replaced by 36 trees of 1" diameter instead
of just twelve trees under the diameter rule. (Did I do that
right? The one-inch trees each have an area of pi square inches,
I better shut up. I am getting in trouble here.
Anyway, the BAD news is that it is expected to apply only to trees
on public property at first. Seems to me the Mayor could just tell
the city employees to follow the rule instead of having a committee,
and ordinance, etc.
