7A 1. Establish and maintain maximum tree cover. The urban forest serves a wide variety of functions that promote the health, safety, and general welfare of residents. These functions include: • conserving energy, by providing shade and evaporative cooling through transpiration; • improving local and global air quality by absorbing carbon dioxide and ozone, adsorbing particulate matter, and producing oxygen; • reducing wind speed and directing air flow; • reducing noise pollution; • providing habitat for birds, small mammals, and other wildlife; • reducing storm runoff and the potential for soil erosion; • increasing real property values; ■ enhancing visual and aesthetic qualities that attract visitors and businesses and serve as a source of community image and pride. All these benefits increase as canopy cover increases. By establishing and maintaining maximum tree cover, the community is able to realize the maximum benefits the urban forest can provide. The maximum amount of tree canopy a given community can support must be determined by analyzing limitations posed by climate and land use. Ordinance provisions Tree ordinance provisions covering planting, maintenance, and removal of trees on public and private land are related to this goal. Performance standards for the amount of tree cover the community hopes to achieve and maintain along streets, parking lots, residential and commercial areas, parks and open spaces should be established in these provisions. A provision calling for development of an urban forest management plan is essential to this goal. This plan should provide for a sustained forest canopy through properly phased tree planting and removal. Specific provisions: O Designate administrative responsibilities DONE: PWs, City forester/arborist, PR&F Comm O Develop a comprehensive management plan How would we scope "comprehensive"? O Resolution of conflicts between trees and structures Do we touch this, aside from public situations? O Planting requirements Do we go beyond Chap 1127? O Permit required for activities that may damage city owned trees RoWs vs Public property O Permit required for activities that may damage protected private trees Chap 1127 only Commented [JK1]: Promote maximum tree cover.�Thiscan be done by city property action, new and re- development requirements, and residential encourag Commented [JK2]: Focus could be along major highways — MV Blvd, 35W, Hwy 10 Commented [JK3]: Applies to city Rows, green space and parks Commented [JK4]: Applies to Rows (rain gardens), green space and parks Commented [JKS]: Focus on main thoroughfares, MV Blvd 1 Commented [JK6]: Ne/Re-development chapter 1127, disease chapter 605 Commented [JK7]: can coverage percent (public and private) be estimated based on satellite views? 11 Commented [JK8]: Can we rely on 1127 and 605 as key elements ofthe "plan"? Commented [JK9]: Phased management would generally apply if replacing significant diseased or storm damage trees. MV is essentially fully developed, so phased removal and plant is not very practical.
