ANALYSIS OF CURRENT PLANS, POLICIES, AND ORDINANCES removing all non-functional turf on City property over the next few years and public trees in those areas will no longer receive the irrigation that was associated with the turf. To account for this loss of automated sprinkler irrigation, the City should consider installing drip irrigation or instituting a summer deep watering program for new and young trees. In addition, the City should also increase efforts for planting more trees on private property, to make up for any potential future tree deaths resulting from the lost sprinkler irrigation. Solar Shade Control Act The Solar Shade Control Act (Sections 25980 — 25986 of the Public Resources Code) was originally passed by the California state legislature in 1978 to give solar collectors access to sunlight, and limit shading from trees and shrubs. Under this Act, "a tree or shrub cannot cast a shadow greater than 10 percent of a solar collector absorption area upon that solar collector surface at any one time between the hours of 10 a.m. and 2 p.m. local standard time if the tree or shrub is placed after installation of a solar collector." The Act was amended in 2009 to allow for trees that may be partially or fully shading solar collectors to remain if they were planted before the solar collector was installed. Under Section 25984, this Act also does not apply to the replacement of a tree or shrub that had been growing prior to the installation of the solar structure, or a tree or shrub that is subject to a city or county ordinance, such as Pleasanton's Tree Preservation Ordinance. Therefore, a resident that wants to remove a tree that is covered under the current Heritage Tree Ordinance to install solar collectors, would not be exempt from getting a tree removal permit. California Green Building Standards Code, Title 24, Part 11 (CALGreen) Under Chapter 5 of the California Green Building Standards Code which specifies requirements for Nonresidential Mandatory Measures, section 5.106.12 (Shade Trees) requires that certain areas be covered with tree shade within 15 years of the project. Surface parking areas must have trees installed that provide shade over 50 percent of the parking area, while landscape areas and hardscape areas must be planted with trees that provide shade for at least 20 percent of those respective areas within 15 years. Both surface parking areas and hardscape areas can have solar collector shade structures or other roofed shade structures as an alternative to shade trees CITY OF PLEASANTON URBAN FOREST MASTER PLAN 1 151
