291 Mr. Mercer concurred with Mr. Tarver's statement. He mentioned that it would be easier to make it an emergency access now and make it a full service road later if it were warranted or if the neighbors wanted it. He supported making Martin Avenue an emergency only access, building four lanes on Stoneridge Drive and setting aside the rest of the area for a park, berms and easements to provide options for a future council. Mr. Tarver indicated that he did not want to close the possibility of affordable housing in a medium density zoning. Mr. Butler stated that he would support medium density zoning. He explained that the residents initially wanted a two- lane road with single family housing; they have agreed to having four lanes and medium density. High density would have a significant impact on the neighborhood. With regard to the connection between Staples Ranch and West Las Positas, Ms. Mohr inquired what projection the staff had for park use and the time expectation for its development. Mr. Lee replied that the park is designed not just for the immediate neighborhood but for the entire community. Its development would depend on the financing that can be worked out with the landowners, presumably when the road is completed. Ms. Mohr asked how much street improvement would be necessary for this emergency access to have the capacity to be a full service road, should the neighbors decide they want that to get to the park. Mr. Lee answered that if a right-of-way allotment was made, a gate or fence could be put up which could eventually be removed. Mr. Mercer commented that this would be another circuitous route through West Las Positas. Traffic problems would start when cars turn off from an eight-lane 1-580 freeway to four lanes on E1 Charro Road. He suggested leaving it as an emergency access road like Martin Avenue, that could always be opened in time. It was moved by Mr. Butler, and seconded by Ms. Mohr, that staff recommendation numbers 1 to 18 be approved with the following changes: Martin Avenue would be used as an emergency access only; Recommendation No. 3 - include redesignating 17.5 acres of the Chu property to medium density residential; Recommendation No. 18 - delete any reference to any specific amount of money and include working out an equitable agreement with the property owners and the County to finance the necessary improvements; Recommendation No. 6 - change the wording to say "...no connection to E1 Charro Road until improvements are completed."; Recommendation No. 5 - include noise mitigation for for houses where the roadway design cannot accommodate normal noise standards. -12- 9-5-89
