There is an existing leach field on the site for the existing house. The applicants have conducted research and have not been able to locate exactly where it is on Lot 1. Staff has added a recommended condition of approval, that if the leach field is discovered during construction, it be removed and disposed of in a landfill. '['here is an existing septic tank on Lot 2 which will be removed as part of the project. Prior to the occupancy of the homes, staff has added a recommended condition of approval that the applicants extend the existing water line in Clara Lane to the western terminus of this project. The applicants have agreed to this condition of approval. The applicants are proposing to connect their sewer line to a sewer line which is proposed to be constructed in the neighboring Hatsushi property to the west. If this project is developed before the Hatsushi project, it is likely that the applicants will need to connect the proposed sewer line to the existing sewer line in the northern part of Clara Lane. Staff has added a recommended condition of approval that the proposed street light design match that of the existing street lights on Clara Lane by Vineyard Avenue (see attached photographs, F,xhibit C). The applicants have agreed to this condition of approval. Geotechnical Studies The Vineyard Avenue Corridor Specific Plan requires site specific geotechnical studies be completed for new development in the plan area in order to evaluate and necessary geotechnical mitigation measures. Geotechnical studies by Korbmacher Engineering dated "Received June 28, 2006" and "Received October 23, 2006" were prepared for the proposed site and peer review reports were prepared by Alan Kropp and Associates on September 29, 2006 and November 22, 2006. The native soil on the site consists of stiff to very stiff silty clay and gravely clay. 1'hc Korbmacher Engineering report includes recommendations about fill compaction and how to reduce the potential for differential settlement among other engineering concerns. As shown in the peer review report, Alan Kropp and Associates concurs with the recommendations outlined by the Korbmacher Engineering report. Staff has added a recommended condition of approval that the project adhere to all of the recommendations of the geotechnical studies. Clara Lane Extension Currently, the improved portion of Clara Lane ends shortly before this project site. As part of this project the applicants will dedicate the northern portion of the property for the extension of Clara Lane. As part of the project, the applicants will construct this extension, unless another arrangement is made with the owners of the Hatsushi property, and agreed to by the City. The extension will not include a sidewalk, similar to the other improved sections of Clara Lane. Once the extension is accepted by the City, the Clara Lane extension will be a publicly owned and maintained street. Case No. PUD-56 Plarming Commission Page - ! 2 -
