INITIAL STUDY – 90-160 ALBRIGHT WAY AND 14600 WINCHESTER BOULEVARD ATTACHMENT 1 APPLICANT’S TREE PRESERVATION STATEMENT M E M O R A N D U M To: Geoff Bradley, Joel Paulson and Fletcher Parson, Town of Los Gatos From: Mike Keaney Date: 2/4/11 Subject: Albright Way, Tree Preservation After visiting the site and reviewing the conceptual site plan we are proposing to use our best efforts (we do not know for certain the impacts of grading and utilities on the existing trees) to preserve trees in the following locations: On the slope adjacent to the existing residential uses all of the trees behind the masonry wall that is currently on the site can be preserved. This includes the following trees: 25, 26, 27, 28, 106, 107, 116, 115, 114, 113. On the southern property line adjacent to the existing residential near Charter Oaks Drive we will setback parking 15’ from the property line. This will allow for the preservation of the majority of the trees along this edge of the project. This applies to the following trees: 124 – 132, 134 – 141. Along the railroad right of way the majority of our improvements will be in areas of the site that are already developed with parking and other improvements. This should allow for the preservation of many trees in this area including: 324, 326-346. Of course, if any of these trees must be removed, we will follow the tree mitigation requirements.

EXECUTIVE SUMMARY The purpose of this Air Quality and Greenhouse Gas Assessment is to evaluate potential short‐ and long‐term air quality and greenhouse gas impacts resulting from implementation of the proposed Albright Way Development project (project). The project is located in the Town of Los Gatos (Town), along Albright Way, southeast of the State Route 85 (SR‐85) and Winchester Boulevard interchange. The project proposes a Planned Development zoning that will allow for flexibility in the ultimate mix of land uses on the project site. The project may consist of office alone or a mix of office and high‐density /senior residential units. As currently proposed, the project could include up to a maximum of 550,000 square feet of office space, or a combination of less office space with residential uses. Residential uses could include up to a maximum of 516 high‐ density dwelling units or 600 senior residential uses. This Air Quality and Greenhouse Gas Assessment evaluates Scenario 1 as identified in the Albright Way Development Traffic Impact Analysis (Traffic Impact Analysis), prepared by Hexagon Transportation Consultants, Inc. on March 17, 2011. Scenario 1 consists of the replacement of 250,000 square feet of existing office park buildings with
