I RFP No. 20-154 k Santiago Park Main Street Entrance Design BASIS FOR CHANGE ORDER Backnr-I„tA 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 defined a series of components to be included in the design. From our research of available information, several site visits (including the original kick-off meeting), 2 draft submittals of concept plan sets and comments made on them by City staff and other communications, a final concept plan has been created and is shown on the next page. It is part of the basis for this change order proposal. The original contract between the City and H&A had been established to remain under a $250,000 funding limit with scope reductions by eliminating view deck incursion into the 100 year floodplain of Santiago Creek since the incursion would lead to higher construction costs plus extensive secondary impacts and increased engineering fees. For this change order proposal, the funding limit has been dropped and the view decks impinge on the FEMA floodplain triggering the impacts that were avoided by the initial contract scope. City mutipunsibilities ENVIRONMENTAL DOCUMENTATION H&A has included the design and permits related to the design within our scope and fee; however, the City will need to take some supportive actions due to the changed configuration. We believe the new configuration will render the present Categorical Exemption for the project void (note the existing document also does not have the correct project location). The criteria from the CEQA law is as follows: (a) Grading on land with a slope of less than 10 percent, except that grading shall not be exempt in a waterway, in any wetland, in an officially designated (by federal, state or local)... The placement of the view decks and supporting retaining walls will be on a slope more that 10% and in a waterway. The result would be the need to restart the environmental process with the outcome likely a Mitigated Negative Declaration. Also jurisdictional delineation of wetlands and identification of limits of riparian areas will be necessary. H&A suqqests the City address this proactively once the design information is available to prevent significant delay GRANT DOCUMENTATION H&A has been provided a copy of the City application for a Coastal Conservancy Grant of $250,000 for the planning and design of these improvements (hence the original contract limit of $250,000). Upon review of the application, based on the new project configuration, there are significant non -compliances with the following sections that we believe may need to be addressed by the City and resolved with the grant agency before requesting reimbursement: 11 — Environmental Review — revised document must be reviewed and approved by grant agency 12 — Permits — originally only building permit, now Federal and State permits for work within 100 year floodplain 13 — Wetland/Riparian Area — original response was no, now will be yes since work within 100 year floodplain HUNSAKER&ASSOCIATES IRVINE, INC.
