number of different formal and informal functions and gatherings. The Phase II Specific Plan could consider a range of amphitheater types for future consideration. Adequate site area is necessary to manage and absorb peak arrival periods of vehicular traffic, queuing and parking. Typically, audiences arrive within 45-20 minutes before an event and must be able to park and be seated by curtain time. Ingress of vehicles into the site must be accommodated quickly, efficiently and intuitively. Both vehicular and pedestrian circulation systems must be designed with a minimum of hazardous crossing points and bottlenecks. If the site cannot absorb this traffic, it may back up into City streets and adjacent neighborhoods. Site and building areas also need to accommodate audiences and "front-of-house" services, including toilets and concessions. While scheduling may allow dual use of indoor lobby space for these functions, the significantly larger audience for outdoor events puts some pressure on the fullest possible development of toilets and concessions areas within the indoor theater lobby. For overlapping events, this may not be feasible, in which case dedicated outdoor facilities may be required. Site development must recognize the need to secure audience area from the outside for ticketed events. This may require a combination of security fencing, adjacent buildings and/or landscape features. The audience area of the amphitheater should be secured during performances to prohibit access by "gate crashers". Site development should include an acoustical barrier to block noise from off-site sources. Seating and sightlines within the amphitheater will require a landscape bowl with a slope of at least 1:12. Fixed chair, and blanket seating on the lawn are close to the ground and will benefit from a bermed landscape that will create an acoustical shadow within the audience area. Orientation of the bowl must be carefully planned so as to keep highway traffic sound out of the audience environment. Alternative Site Analysis - The advantages to locating the CAC at the Valley Avenue site include: · This site is more in keeping with neo-traditional principles: locating community-oriented uses adjacent to commercial and residential uses, thus creating a synergy of mixed uses within walking distance of one-another. · This location improves and makes accessible the open space around the existing wetlands while preserving the large central open space between Valley Avenue and Bernal Avenue. · The CAC creates an interesting edge at and expands the existing water quality/detention basin/wetlands. · Views into the large open space from Bernal Avenue are unimpeded. · Sound attenuation into and out of the CAC is improved because of the relatively remote location, and the freeway noise is more easily controlled (Attachment 3). · The CAC is more visually prominent from 1-680, thus creating a regional landmark.
