INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
Brinker Substation Tree Survey
BACKGROUND:
The Brinker Substation site was selected through the Public Involvement Process in late 2015 and then
approved by the Public Utilities Board and Denton City Council in early 2016. Using the Denton
Development Code, Subchapter 13, Freese & Nichols conducted a tree survey for the Brinker
Substation site to determine how many trees of various categories would be removed. Although DME
is exempt from any mitigation requirements as stated in Subchapter 35.13.7.A.2.c.v, (“Public Utilities
may be exempted from these requirements upon filing route plans prior to tree removal or construction,
which satisfactorily demonstrate that the proposed installation lies within routes previously established
by a current Master Plan for transportation or public utilities, or within an existing easement recorded
prior to the effective date of this ordinance”) DME intends to follow the requirements stated in the
Denton Development Code. The following exhibits show the substation site that was surveyed and the
chart to determine the total caliper inches to be mitigated. Per this plan, and consistent with the
Denton Development Code, DME will transfer $121,938 into the Tree Mitigation Fund in connection
with the Brinker Road substation project. In addition to this, DME will prepare a landscape plan for the
substation buffer. This is currently not complete but will be completed at part of the project.
