EXHIBIT A- SCOPE OF SERVICES <br /> operations. Based on this review, Woodard & Curran will compare the existing standards to the criteria <br /> developed in Subtask 4.1 and other industry standards and will make recommendations for modifications or <br /> additions to the standards to improve their use for private and public development. Recommendations will <br /> be in the form of annotations/comments on the relevant sections of the existing documents that the City <br /> should consider in updating its design standards. <br /> Subtask 4.3— Identify System Deficiencies. Using the hydraulic model and based on the criteria <br /> established in Subtask 4.1, Woodard & Curran will evaluate the performance of the existing sewers, pump <br /> stations and force mains under existing and future dry and design wet weather flows. Capacity deficiencies <br /> will be identified based on the performance criteria established in Subtask 4.1. Thematic maps and <br /> hydraulic gradeline plots will be prepared to present the identified capacity problem areas. <br /> Subtask 4.4— Develop Capacity Improvements. Based on the results of Subtask 4.3, Woodard & <br /> Curran will identify the need for improvements to address existing or potential future capacity deficiencies in <br /> the system. As needed, Woodard &Curran will test solutions to identified capacity deficiencies. Solutions <br /> may include upsizing or paralleling existing pipes, upgrading pump stations that lack sufficient firm capacity, <br /> consolidating flows in new sewers or existing sewers with available capacity, implementing flow diversions <br /> at critical locations, or sewer rehabilitation to reduce I/I. Based on preliminary model results and discussion <br /> with City staff, the alternatives will be refined and focused on the most viable solutions for more detailed <br /> project development. <br /> Woodard & Curran will evaluate potential project alternatives in further detail, including review of projects <br /> sites on aerial mapping or in the field. The purpose of these evaluations is to confirm the suitability of <br /> pipeline alignments, and identify any design, constructability, permitting, or environmental issues that could <br /> potentially be"fatal flaws"or that should be considered in project development. Woodard &Curran will <br /> develop planning level cost estimates based on the most viable construction method for each potential <br /> solution for the identified deficiencies. <br /> Woodard & Curran will develop a plan for recommended sewer system capacity improvements, including <br /> project priorities and estimated capital costs, and construction schedule (durations). Costs for <br /> recommended improvements will be based on City's historical costs for sewer projects, as available, or <br /> data from other similar agencies compiled by Woodard &Curran. Based on model results, Woodard & <br /> Curran will also allocate the improvement costs to existing versus future users. To the extent possible, <br /> identify which development projects benefit from future infrastructure improvements. <br /> Subtask 4.5—Capacity Analysis TM. Woodard &Curran will prepare a draft TM to document the <br /> methodology and results of the capacity evaluation under Task 4. <br /> Task 4 Deliverables: <br /> • TM on design storm and hydraulic criteria <br /> • Review comments and recommendations for modifications to design standards <br /> • Thematic maps and hydraulic gradeline plots of predicted capacity deficiencies <br /> • GIS maps and summary tables of proposed capacity improvements <br /> • Proposed capacity improvement project descriptions, costs, and priorities <br /> • Results of I/I reduction analysis (to be incorporated into Master Plan report) <br /> • Draft and final Capacity Analysis TM <br /> Woodard &Curran -6- 12/20/21 <br />
