generated, which contributes further to atmospheric warming. The planting of large- canopy trees can thus help reduce urban temperatures and energy demand, while at the same time providing a variety of other environmental and esthetic benefits to the community. Large- canopy trees can eventually shade most of a front yard, which may concern some neighbors who want to grow gardens, or who wish to ensure good access to light during the winter. But since most people who grow vegetables have backyard gardens, streetside trees do not conflict with their gardens. And since broadleaf trees lose their leaves in fall, they do not significantly reduce the amount of light that reaches homes during the winter. However, the Project must be flexiable and accomadate personal preferences. The width of a standard city lot permits the planting of at least one, and often two trees. Generally, it is best to plant small- canopy trees no closer than 20 -25 feet apart, and medium- and large- canopy trees no closer than 30- 40 feet apart (Appendix K). Where two new trees are to be planted in front of a single dwelling, it is preferable that they be of the same species so that they can develop at the same rate; otherwise, the more vigorous tree species is likely to eventually dominate the site, to the detriment of the other. Likewise, if an established tree (or trees) exists close by a proposed planting site, it may be best not to plant another tree at all, because the new tree will develop a misshapen crown on that site. New Project Leaders often find it helpful if the City's NeighborWoods Coordi- nator accompanies them at first, until they feel comfortable performing this step themselves. THE PRELIMINARY PLANTING LIST After the above factors have been taken into consideration, a list containing the following information for each site is submitted by the Project Leader to the City's NeighborWoods Coordinator (Appendix L): 1. Address of proposed planting site 2. Occupant's name 3. Occupant's telephone number 4. Owner's name /address /telephone (if occupant is not the owner) 5. Proposed number and size of tree(s), e.g., "2 large" 6. Proposed location of tree(s), e.g., "one tree 15 feet west of driveway and one tree 10 feet east of fire hydrant" 7. Comments HANDLEBAR SURVEY BY NEIGHBORWOODS COORDINATOR After the City's NeighborWoods Coordinator receives the list of proposed planting sites for a given project, the information is entered onto the City's computerized Tree Request List (see sample in Appendix C). A lot map of the project area is then photocopied from Public Works base maps, and the proposed planting sites are marked on the map (see sample in Appendix D). 4
