A. Street Tree Requirements. Street trees shall be planted as directed by the public works director. In lieu of planting the trees, the subdivider shall deposit with the city a street tree fee. Such fee shall provide the tree purchasing and planting by the city and shall relieve the subdivider of any further street tree obligation.
B. Landscape Requirements. Landscaping may be required by the advisory agency. All such landscaping shall be installed and maintained by the subdivider until the city accepts the subdivision. In addition, the subdivider may be required to provide irrigation facilities for the landscaping.
C. Planting and Installation Guidelines. All street trees and landscaping required within a public right-of-way or public service easement or on other city property shall be planted and installed in compliance with the following guidelines:
1. All trees, shrubs, ground covers, vines and turf shall be of a type approved by the public works director and, to the greatest extent practicable, shall be of a drought- resistant and drought-tolerant type of variety.
2. Irrigation controllers shall be equipped with independent station control, multiple start time and multiple program capabilities.
3. All irrigation systems shall include independent station or “zone” moisture sensors. Plant materials with similar watering requirements shall be irrigated using common controller circuits.
4. Irrigation systems shall be designed to match precipitation rate to evapo- transpiration potential of selected plant materials given soil percolation rates.
5. Whenever possible, irrigation systems shall include drip irrigation, individual adjustable bubblers, weep-tubing, matched precipitation sprinkler heads and other low volume systems.
6. Wind direction and wind speed shall be considered as a design element for the purpose of minimizing overspray and to provide even precipitation distribution.
7. A water audit shall be performed before installing plant material, to ensure equal precipitation rate.
8. Wherever practical, landscape installations shall be performed with minimum soil compaction. All attempts shall be made by the landscape contractor to keep construction equipment and vehicles off the landscape site once final soil tilling and grading is complete.
