A. It
is the intent of the city to impose standards and regulations in regards
to the planning, installation, and maintenance of the public and private
landscape that provide aesthetic and functional amelioration to the

need to conserve water in all of its varied uses in order to meet
the needs of its growing population.
B. This
chapter is intended to establish standards and regulations for new
residential, industrial, commercial and institutional development.
The provisions of this chapter shall not apply to existing development.

enclosures shall be provided for each development. Each enclosure
shall consist of three solid walls and a gated fourth wall.
L. Roof
mounted mechanical equipment, tanks, ventilating fans and similar
equipment shall be screened from the view of adjacent properties and
