KOLL The Koll Company September 23, 1986 Bank of Pleasanton 555 Peters Avenue Pleasanton, CA 94588 4309 Hacienda Drive Suite 390 Pleasanton California 94566 (4151460-0300 Attention: Larry Lindsey, Chairman Pleasanton Planning Commission Dear Larry: ~ ~~/ It has come to our attention that some of the neighbors to the north of Holl Center Pleasanton are concerned about the Arroyo repair work that is in progress on the south bank of the Arroyo. The purpose of this letter is to bring you up to date on what has occurred and what remains to be done. As you are aware, we are required to dedicate the land from the top of the Arroyo bank to approximately the center of the Arroyo. As a condition of accepting dedication of the land, Zone 7 required that a significant slide area at the west end of the Arroyo area be repaired and that other unstable areas along the Arroyo be stabilized. The purpose of stabilizing the bank is to prevent future additional elides and loss of large trees along the bank. In order to make the necessary repairs, fairly substantial amounts of undergrowth and some trees in the 8" diameter or under range and some dead trees had to be removed. When the entire Arroyo zone is considered, this plant loss is netually fairly minimal. However, in three specific areas the viauel impact wee fairly significant. In those areas we are going to plant deciduous trees at least ZO' tall, on no less than 80' centers. Additionally, we will be planting evergreen type plants at least 10' tall on no leas than 10' centers and grass seeding the bank. It should be understood that this Arroyo bank repair planting is in addition to the 30' to 85' wide landscnped area that is to be provided in the landscape area south of the top of bank in what hea been referred to as the Arroyo landscape zone.
