Vl. General Criteria This project satisfies the general criteria through: A. Increased Mitigation and Enhancement Caltrans was responsible for mitigating adverse visual impacts due to the project by installing noise barriers and/or planting shrubs and vines as visual screens after construction was completed under Caltrans' separate highway planting and irrigation replacement contract. Replanting occured within the remaining right-of-way width. However, this replacement did not address increased carbon dioxide emissions from increased traffic flow. Carbon dioxide from 1-880 affects a far greater area than areas immediately adjacent to 1-880. The Caltrans 1-880 Widening Project reduces available landscape planting space because the additional lanes being installed use space within the right-of-way, leaving less available planting area. The City of San Leandro grant proposal proposes to install 654 trees city-wide. This proposed mitigation is compatible with the safety/operation of the new transportation facility as it consists of tree planting in available sites in city locations entirely outside of the right-of-way of the related transportation facility. Any planting that is to occur will in no way compromise or interfere with any roadway safety or operation. This proposed mitigation would occur without limiting any planned/future improvements to the transportation facility as the proposed mitigation will occur in planting sites throughout San Leandro outside of the I880 right of way so there will be no conflict between future 1-880 plans and the proposed planting. The additional planned mitigation comprises five main project categories. (See Exhibit F for locations.) Street Tree Planting - Sites will be targeted based on available planting opportunities and the need for large stature trees. Early in 2000, the City will approve its Street Tree Master Plan, which will serve as a blueprint for developing specific tree planting plans for neighborhood streets. During the rest of 2000, staff will meet with neighborhood groups to develop those specific street tree planting plans. Those plans will identify specific sites for street tree planting that exist citywide. Although it is anticipated that several thousand sites will be identified, this project would fund planting at four hundred sites that will receive a priority for planting based upon identified need for large stature trees, completion of a street planting plan, and the City's ability to complete the plantings. Trees will either be planted in an existing planter strip located between the sidewalk and curb, within a paved over planter strip, or behind the sidewalk within the public right of way. The planting sites will be limited to two hundred sites that require concrete Page 4
