Irrigation System The system is completely automatic and programmable so that we can water the plants to establish them after they are planted. We can then reduce the water to provide only for the plant needs. The irrigation system will be scheduled so that the water applications change throughout the year as the plants needs change; in winter, no water; in summer, only supplemental water after establishment of the plants. The irrigation system combines the use of water application to the individual plants by the use of bubblers and spray applicators to groundcover areas. This combination is best for use of water, plant health and cost considerations. This is an underground system that will preclude vandalism of irrigation lines and is not visible. Water is provided through irrigation heads that are large enough so they will not plug up which is a maintenance problem with some systems. There are many irrigation heads on this project. This is because we are placing water at the plants so that the water is used by the plant. This means that we are using less water by efficient placement, not more water because there are more sprinkler heads. Plants The plants proposed for this project were selected so that, in addition to giving "welcome and notice" that you have arrived in San Luis Obispo, they can handle the site conditions of southern exposure, highway and soil . These plants are all drought tolerant, water thrifty and tenacious after establishment (see attached list) . The landscape design provides for screening of some areas and for views of others such as San Luis Mountain. 3'/ A� �► city of San tins OBISPO COUNCIL AGENDA REPORT Award City Plan No. K-01Y Page 2 Recommendation By motion approve the award of a contract in the amount of $28,444.00 to Karleskint-Crum for installing irrigation on the Santa Rosa Street Islands and authorize the mayor to sign contract documents.
