`>COP ()1- VVCj4�h AfvID :JCI IF_DLiL plan is intended as a guideline to assist in the planning efforts for the lake design and the future environmental planning documents. Deliverable: Lake management plan (included in study report) and exhibits showing recommended tasks, procedures, frequency, equipment, and troubleshooting recommendations r Based upon input from the City, Dudek will select a recommended lake rehabilitation plan from the alternatives developed. The recommended lake rehabilitation plan will be detailed to the preliminary design level, It will provide sufficient information for detailed preliminary cost estimating. The recommended plan will show size, location, type, and dimensions for each propose lake system improvements. The lake system improvements will include but are not limited to lake liner improvements, aeration system improvements, circulation system improvements, water quality system improvements, water feature improvements, fishery/wildlife enhancements, and maintenance features. A preliminary design exhibit and detailed narrative description will be prepared to present each component of the rehabilitation plan. The Lake Rehabilitation Plan exhibit will be a compilation of the design of each of the lake component systems Deliverable: Preliminary Lake Rehabilitation Plan exhibit showing all recommended improvements, and rehabilitated lake system components w Dudek will prepare a preliminary cost estimate for implementation of recommended rehabilitation plan including preliminary construction quantities and unit costs. The quantities will be developed from the preliminary rehabilitation plan developed for Centennial Park Lake. Unit costs will be based upon previous project cost information for similar projects in the area compiled by Dudek and approved by the Client. Dudek will also prepare a lake operation cost estimate for the recommended lake plan and concept level cost estimates for the alternative plans. The estimates will be included in the project report. Deliverable: Engineer's estimate of probable construction cost (included in study report) f Dudek will develop a phased project implementation plan to give the City guidance on construction sequence of the lake rehabilitation plan. The lake is part of a high demand high usage park with mixed usage demands for soccer field space, trail system access, public access roads, a high school campus, and a satellite campus of Santa Ana College. This will require coordinated implementation of the proposed improvements in order to minimize disruption to the other park uses and allow for timely implementation of the proposed improvements. Dudek will develop a preliminary construction phasing exhibit to demonstrate how the project can be implemented to minimize park user disruption and allow for rapid construction of the proposed improvements. Deliverable: Preliminary Lake Rehabilitation Phasing Plan exhibit showing phased implementation of all recommended improvements and recommended staging of the project. It is anticipated that the project will be exempt from CEQA laws. Dudek will file a Notice of Exemption with the County of Orange on behalf of the City to exempt the project; if applicable. Dudek will also provide CEQA compliance recommendations for the project based upon the recommended rehabilitation plan. The recommendations will generally provide guidance to the City DUDEK Centennial Park Lake Circulation and Aeration Study 14 25B -16
