Pleasanton Avenue (south) Access · This indirect access extends southward along the western edge of the sports fields to Valley Avenue, and would serve as a secondary connection to south Pleasanton. · Limited shared parking will be sports fields would be possible by way of this road. 2. Comparative Noise Summary At the January 4, 2005 meeting, the Council asked City staff and consultants to prepare a comparative analysis of the noise issues relating to the two alternative CAC sites. A conceptual analysis (Attachment 3) has since been prepared by MDF working with their arts facility consultant. The conclusions of the analysis are presented below. "The analyses of site locations, given the dynamics of off-site and on-site generated sound would clearly favor a southern (Valley Avenue) location for the CAC and amphitheater. This location makes it easier to mask freeway noise while placing the performance sound source at a location that is the farthest from surrounding neighborhoods. "It is very possible that a location toward 1-680 would actually be more advantageous with respect to site sound issues. Siting venues at the opposite end, in close proximity to Bernal Avenue, are likely to create unwanted site sound into neighboring areas. This is very common in urban park settings where amphitheaters exist. Sound from events in an amphitheater closer to the freeway will have less impact because of greater open space, less housing density off axis, and acoustical "masking" by 1-680 traffic. The greatest concern would be residences on the Ridge, but as long as speakers are appropriately aimed and oriented, this should not be an issue." 3. Permeable Pavement Materials At the January 4, 2005 meeting, the Council asked staff to prepare a summary regarding the use and aesthetics of permeable pavement materials. The following summary, including the Attachment 4 photographs, are presented in response to this request. There are three general categories of permeable pavement: Permeable concrete/asphalt, structural grid systems underlying turf, and interlocking pavers. Permeable pavement that works properly recharges local aquifers, reduces flooding, reduces the need for expensive storm water infrastructure, allows pollutants to be broken down naturally, and therefore, contributes indirectly to healthy riparian habitat. All three materials require a sub-grade that is also permeable to work properly. Therefore, expansive soils will inhibit the efficiency of each paving method to reduce runoff, requiring the use of sub- drainage systems. Following is a brief description and assessment. Permeable Concrete/Asphalt - Conventional asphalt or concrete with the fine material left out of the mix. Virtually all surface water is absorbed before reaching the gutter. SR 05:028 Page 8
