ARTICLE 1. IN GENERAL
This chapter shall be known and may be cited as the Denton Landscape Code
Sec 31-2 Statement of Purpose.
The intent of this article is to promote the immediate and long-term public health, safety, economic
stability and general welfare by establishing and managing the City's urban tree canopy coverage
This article is Intended to promote the following general purposes
(1) Preservation, protection, and enhancement of the ecological and aesthetic attributes of the
City
(2) Ecological stabilization through urban forest management that contributes to the processes of
air purification, oxygen regeneration, ground water recharge, storm water runoff retardation,
and promotes energy efficiency and water conservation, thereby abating noise, heat and
glare
(3) Protection, preservation and advancement of the urban forest's appearance, character and
value that includes all properties within the community, and that contributes to a strong sense
of neighborhood, community, and quality of life
(4) Protection and preservation of native and specimen vegetative species, their ecosystems and
natural habitats and preventing damage to and unnecessary removal of vegetation during the
land development and construction processes
(5) Acknowledgement that trees and landscaping add value to property, protect public and private
investment to the general benefit of the City and its residents
(6) More specifically, this article is intended to
a Protect water resources, flood plains, environmental quality, and the natural and man-
made physical and visual quality of the City
b Mitigate the effects of impervious surface land coverage by structures and paving that
tend to Increase ambient air temperature and generate greater water runoff causing
erosion, flooding, and water pollution
c Prevent clear -cutting and mass grading of land by encouraging the use of natural terrain
for building sites, and by providing cluster development incentives
d Promote native plant species preservation and replenishment, and encourage the use of
drought tolerant and low water usage vegetation
e Provide incentives for tree preservation
f Protect and provide wildlife habitats
g Require landscaping and screening to promote land use compatibility and improved
aesthetic quality
h Promote soil conservation by minimizing natural terrain disturbances, thereby reducing
sedimentation, and air and surface water pollution
