Overall Summary
Five Major Elements:
1. Environmentally Sensitive Area (ESA)
2. Tree Preservation
3. Buffers
4. Street Trees
5. Landscape Area
Preserved Trees will now count for Landscape and Canopy
New plantings will require diversity of tree age/species
Low Impact Development Standards
No Pervious Area Credit
No ESA Credits for Canopy of Landscape Area
Buffer and Landscape Area based on Flexible Point System
Environmental Sensitive Areas (ESA)
Text was re-organized/clarified to make process such as ESA field assessments, project reviews,
and map amendments easier to differentiate and follow.
Tree Preservation
Requirements for a Tree Removal Permit have been updated to more clearly define that such a
permit is needed for any removal authorized under a Tree Survey and Preservation Plan.
Enforcement provisions within the Tree Preservation subsection have been updated to reflect the
same provisions currently in the DDC.
Protected Trees is new
Heritage Tree is any healthy tree with an eighteen (18) inch or greater dbh.
Quality Tree is all healthy trees that have a dbh that is greater than six (6) inches, but is less than
eighteen (18) inches.
Large Secondary Trees is all healthy Mesquite, Bois Arc, Locust Hackberry and/or Cottonwood trees
with an eighteen (18) inch or greater dbh.
Secondary Trees is all healthy Bois D' Arc, Hackberry and/or Cottonwood trees that have a dbh that is
greater than six (6) inches, but is less than eighteen (18) inches.
Non-Protected Trees
Mesquite unless part of a Preserved Habitat or Conservation Easement
Honey Locust (thorned), unless part of a Preserved Habitat or Conservation Easement
Crepe Myrtle (multi-trunk)
Diseased or dead trees
Trees that poses an imminent or immediate threat to persons or property
Any tree listed on the Texas Department of Agriculture Noxious and Invasive Plant List
Cannone showed different tables with Preservation & Mitigation requirements for Non-Infill Lots and
Protected Trees.
Protected trees: 30 percent DBH minimum preservation and 70 percent DBH mitigation.
Cannone then showed an acre lot using the i-Tree Design and planted with trees to show what is
needed for that lot. Currently the only required preservation are for quality or secondary trees.
Using that same lot he showed different scenarios using the i-Tree Design tool with explanation.
Something new that staff included in the infill development is a suggestion to allow a decrease
preservation for properties that need the infill development. That definition is: Development on a
vacant parcel or groupings of vacant lots within an existing block surrounded by existing development
that is contiguous on at least two (2) sides for corner lots and contiguous on at least three (3) sides for
interior lots (existing development located directly in front on the other side of the street may count as
a side for interior lots only), no greater than two (2) acres in size, and is served with all or most public
services and facilities, including but not limited to water, wastewater and drainage.
Mitigation Tree Replacement
Current: $125 per inch
Proposed: $286 per inch which includes purchase, planting, water tap, meter and irrigation
Texas Supplement to the Guide for Plant Appraisal published by the Council of Tree and
Landscape Appraisers: $202/inch average cost per inch of purchasing a tree and keeping it alive for
one year.
Tree Preservation Relief
Included Cross-Reference - Currently in Subchapter 3 of the DDC
Allows a determination of whether Tree Preservation and related development applications, would
if not modified or other relief granted, may unreasonably burden the development of the property.
City Council shall consider whether there is any evidence from which it can reasonably conclude
that the application of all or a part of the provisions of tree preservation may deprive the applicant
of all economically viable use of the property, based on the following factors:
1. Whether there is a unique physical circumstance on the property.
2. Whether the proposed design has minimized the loss of trees to the extent possible.
3. Whether preservation and/or mitigation unduly burdens the development of the property.
Alternative Tree Preservation Plan is new
Reintroduced - Currently in Subchapter 13 of DDC.
Allows a site that cannot meet the strict requirements to present an alternative proposal that meets
the intent of the code to the Planning and Zoning Commission.
Although these provisions have not been used under the current code, Staff felt it was important to
maintain these procedures to allow for flexibility in unique circumstances.
Intended to be used to count Secondary Trees as part of the required preservation or smaller dbh for
Quality Trees or Black Jack and Post Oaks.
Landscape/Tree Canopy Mitigation is new
Landscape Requirements (35.17.6.B):
Payment in Lieu of required plantings where site or easements, encumbrances, physical
constraints, or life safety requirements limit the ability to plant (non replacement) trees.
10% Max Reduction
ADP required for anything above 10%
Next Steps are Planning and Zoning Public Hearing on February 20, 2019 and City Council
Consideration on March 5, 2019.
Briggs concerns include:
1. Not a minimum percentage that has to be saved unless there is an ESA. Cannone added they are
required to preserve a minimum of 30 percent of the dbh. Briggs asked to
make sure that is clear.
2. Glad that secondary is includes but believes 18 inch dbh is too large would like that to be 12 inch
dbh.
3. There is an area in the ordinance that states: No tree will be remove until the final plat is approved.
Developers will cut down trees before the plat is filed
happen. Cannone answered to require a permit for any tree removal and not allow those permits
until the final plat is approved.
Meltzer asked what is the consequences for cutting down a tree without a permit. Cannone answered
it would go through the regular enforcement provisions. We would have to go out and determine
what was removed and assess it that way.
Meltzer then asked if a property is in the floodplain, does staff ever say if you really want to build you
anyway.
Ryan stated where this may come into play would be a two acre spot where most of the trees are in the
only area the land is not in a floodplain. You would need an alternative to plant in the floodplain area
s are in the only area
to build.
There was discussion regarding the acre lot scenarios.
st
Briggs asked about her 1 comment with regard to single family development. Cannone answered it
is exempted as a result of the Texas Local Government Code. Briggs added it would help if the ones
that are Texas Local Government Code are marked as such so people will know.
Briggs then asked about replacement of trees when they die, do we have a way to enforce that.
Cannone answered through the approved landscape plan it will be. Briggs then asked what that
enforcement process be. Cannone answered it is a zoning enforcement.
Briggs would like any alternative plans go through the same process.
Briggs asked if there are there notifications sent? Cannone answered if it is tree removal, there is a
sign that will go on the property.
Meltzer asked if the analysis will come back for the open space master plan. Cannone answered it
will come back when the tree inventory and master planting plan are presented.
