Kay Wilson, Vice President of Hansen Hill Development Corporation, advised the Commission that her firm was under contract to purchase the 148 acre property from the Hansen family. Ms. Wilson elaborated on the actions to date, 1} the Draft Environmental Planning Study prepared by the Applicant's "Development Team" covering the subject property, 2) EIP's Environmental Assessment Study, 3) TJKM's Traffic Constraint Analysis, 4) meetings conducted with neighboring residential property owners and surrounding agricultural land owners. She indicated that the concerns of the agricultural landowners centered on; 1) access, and 2) sewer and water planning. She concluded by indicating the Planned Development Rezoning and General Plan Amendment application submittals were anticipated to be filed in late February. Ms. Wilson then introduced the Project and Landscape Architect, David Gates. Mr. Gates presented a short slide presentation, which included slides of graphics contained within the Draft Environmental Planning Study. From the materials presented, Mr. Gates relayed a preliminary unit count proposal of 290+ units. John DeHorn continued the Applicant's presentation by discussing civil engineering information related to the site. With his review of water service, Mr. DeHorn indicated the need to establish a new water zone to serve the upper elevations of the property. With this discussion, Mr. DeHorn also described the water service infrastructure currently in place and that which will be installed to complete the Zone III water pressure zone. Mr. DeHorn briefly discussed options to establishing a new Zone IV water pressure zone (hydropnematic pumps). In answer to a question from the audience, Mr. DeHoxn discussed the mechanics for selection of a water storage tank site, which would be needed if a new water pressure zone was established. Mr. DeHorn also addressed questions concerning water pressure requirements for fire service, the location of the existing 12' water line stub and how the 12' water line would cross Martin Canyon Creek. Within his discussion of sewer service, Mr. DeHorn indicated that a portion of the site (sloping towards I-580) would present some special sewage problems. In discussing the storm drainage system, Mr. DeHorn discussed the Martin Canyon Creek watershed, the role of the creek for storm drainage, current velocities in the creek, and the hydraulic studies which will be performed in Regular Meeting PCM-7-22 February 2, 1987 : - - . • • conjunction with this project. In answer to a question from the audience, Mr. DeHorn indicated that maintenance responsibilities of the creek following project development had not yet been determined. In his discussion regarding traffic, Mr..DeHorn listed potential access connections (Silvergate Drive, Martin Canyon Road, Dublin Boulevard - via the Valley Christian Center Church site, Hansen Drive, and routes through Donlan Canyon). Mr. DeHorn stressed the need for emergency vehicle access, which ~ might result in the need for a bridge crossing over Martin Canyon Creek. Mr. DeHorn also discussed the potential needs for a paved access paralleling Martin Canyon Creek. The studies performed by TJKM were discussed, including the recommendations for mitigation measures for the Dublin Boulevard - San Ramon Road inter- section. Following the conclusion of Mr. DeHorn's present'ation, the Commission then began its point-by-point consideration of the Draft List of Issues. Under Item 1.1 Site Geology, questions were raised regarding the City policy concerning development on slopes, and the issue of non-point source run-off pollution. In response to general questions from the audience, Mr. Gailey discussed the role the List of Issues would serve in the project's environmental review process. The overall environmental review process was discussed, including discussion of the mechanics of the review and comment process that will be made available to other public agencies. Under Item 1.2 Soils, Mr. Harvey Scudder, Dublin resident, advised the Commission of the presence of a major soil dump, consisting of earth spoils from the Briarhill project, created approximately 20 years previously. Under item 1.3 Hydrology, questions from the audience were raised regarding the potential presence of springs and problems associated with increasing the erosion to Martin Canyon Creek (siltation). Dr. Zev Kahn, Dublin resident, suggested a mechanism be used to establish a fund to address potential creek problems resulting from the project's development (e.g., flooding, run-off, maintenance, slides, etc.). Following a 10-minute break, Cm. Raley advised the audience of the Planning Commission's policy not to start any new agenda items after 10:30 p.m. Cm. Raley indicated his assumption that consideration of the Draft List of Issues would not be completed that evening and would be continued to the Commission meeting of February 17, 1987. Debra Vasquez, Dublin resident, questioned who would foot the bill for the costs for hydraulic studies. Mr. Scudder elaborated on his previous discus- sion regarding non-point source run-off pollution and the cumulative impacts of same. The Planning Commission comments on Section 1 of the Draft List of Issues included Cm. Burnham's direction that the cumulative impacts be considered, especially impacts related to the ultimate upstream development. Regular Meeting PCM-7-23 February 2, 1987 _ ~ - . . • In regards to Section 2- Vegetation and Wildlife, Bob Patterson, Dublin resident, commented that the site contained some of the most significant existing vegetation in the City. Dr. Kahn referred to the Bordeaux Estate project as a visual blight (as regards grading that occurred for the project's development) and called for application of mitigation measures to have trees planted on the subject property following its development. Dr. Kahn also questioned the potential impact to existing mammals after vegetative cover was removed. Mr. Wendling, Dublin resident, inquired as to the future development plans of properties to the west of the Hansen Ranch. Cleo Davidson, Dublin resident, inquired regarding the manner in which "significant" trees and tree clusters would be identified. Mr. Patterson stated a road along Martin Canyon Creek would violate policies included in the City's General Plan. The Planning Commission`s comments on Section 2 included direction from Cm. Petty that a detailed tree inventory be prepared and an inquiry from Cm. Raley as to the adequacy of a 30 foot minimum creek setback. Gm. Raley also inquired on the status of establishing a City Heritage Tree Ordinance. In regards to Section 3- Visual Quality, Ms. Vasquez questioned the manner visual quality from the highways will be assessed. Dr. Kahn again discussed problems he saw with the Bordeaux Estates development scheme, and called for the planting of major trees in backyards of new hillside lots. Mr. Wendling inquired as to the development proposals in the Eastern Extended Planning Area. A member of the audience called for consideration of the visual impacts development on this site would have on the nearby Kaufman & Broad Silvergate Highlands single-family project. Questions were raised regarding LAFCO's role in City annexations and the meaning of Spheres of Influence. Cm. Raley provided the only Commissioner's direction of Section 3 by calling for adequate on- and off-site visual analysis of the project proposal. Discussion on Section 4- Slope Analysis included clarification fr~m Staff regarding Items 4. C. and 4. H., which discussed General Plan policies related to development of slopes greater than 30~. Cm. Petty commented that the Draft List of Issues stated that 44~ of the site has slopes in excess of 30~. The Planning Commission provided no additional comments regarding Section 4. In regards to Section 5- Noise, Russ Tilly, Dublin resident, stated that the issues of changes to ambient noise levels (which he felt would be potentially magnified due to the topographic layout of the Canyon) and impacts of construction noise should be analyzed.
