UNDERSTANDING OF NEED The City of Santa Ana wants to upgrade the Main Street Entrance to Santiago Park to be more attractive for users and provide a positive expression of Santa Ana's high value of park facilities in the city. The Santiago Creek Trail Access plan and related descriptions provided with the RFP define a series of components to be included in the design. From our research of available information and several site visits made to better understand the constraints and opportunities of this site, the H&A Team has identified several potential challenges and developed initial solutions that address them to keep costs within budget and avoid possible delays. Potential Permit Problems RFP No. 20-154 Santiago Park Main Street Entrance Design KEYFACTORS ■ Understanding based on knowledge of the existing project conditions and constraints • Awareness of the community and park users needs ■ Insights gathered by project manager and other team members from doing projects in urban areas ■ Project manager's knowledge of the City policies and procedures from his past work for the City No longer applicable in revised proposal since cantilevered viewing decks eliminated Homeless Encampment No longer applicable in revised proposal since cantilevered viewing decks eliminated No longer applicable in revised proposal since cantilevered viewing decks eliminated. Slope Erosion Apparently due to the ground being highly compacted over time, some of the existing overside drains no longer function and runoff goes over the channel banks. In one location, this has resulted in demolition of the original stone lined overside drain. To ,prevent future damage, the H&A Team proposes to excavate the ton several feet of compacted soil and grade the area to drain back from the channel bank to a stone lined swale consistent with the recent one near the playground area. The additional soil volume will consist of topsoil placed to facilitate growth of the proposed plantings. No longer applicable in revised proposal since pedestrian bridge eliminated. The existing lighting system is not functional as verified by an evening site visit. In addition, the poles and fixtures appear to need at least refurbishment to return the system to operation. Given the apparent age of the existing equipment, replacement would be preferred since the new fixtures would be more efficient and reduce the City operating costs. The H&A team proposal includes replacement of the luminaires poles underground conduits electrical service and all wiring to provide cost efficient, un-to-date lighting for the park and provide benefits to the City and park users.
