M. Retention Pond Design and Overall Project Storm Water Management Report This herein supplemental agreement will address two (2)sites,Pond 2,and Pond 7. The revisions to the overall project Storm Water Management report will also be incorporated with this work. 1. Pond 2,will basically remain the same, and will reflect the design to incorporate the ultimate needs of CR-510. The revisions will consider storm water piping and inlets in the general area, and in consideration of the 4-lane to 2-lane roadway transition. The ENGINEER will evaluate retaining, as best as possible, the location of inlets and manholes, and also address overland flows from private property and driveway access, as these features may have an impact on drainage facilities. 2. Pond 7, is located on the Graves Brothers property. The current location, as previously designed,needs to be relocated,in a fashion,which meets,as best as possible,the location, as preferred by the land owner,and his engineer. The ENGINEER has been provided a Concept Plan, from Schulke, Bittle & Stoddard, LLC, entitled Conceptual Plan for Graves Brothers Wabasso Crossing,not dated. This plan depicts a storm water retention pond in the northeast quadrant of the property. The ENGINEER will re-evaluate the drainage patterns, and the roadway design, and develop a modified design for Pond 7, to best meets the needs of the COUNTY, and consistent with the CR-510 design/plans. The overall intent is to still maintain its proposed outfall. 3. The overall project storm water management report will be updated to reflect: 1) the NEW western termini of CR-510, and 2) any modifications to the storm water management plans for the project, and including the proposed number of storm water retention ponds. The ENGINEER will use this overall report to coordinate with the governing agencies for Storm Water Management Control, and as required the FDOT, for their respective portions of interest to this project. This effort/fee will be contained under the Lump Sum Components of Roadway Design, in "Section V— Compensation." N. Maintenance of Traffic(MOT)Plans MOT plans are required for the revised project conditions. The existing MOT plans will be revised to reflect the NEW western termini and the proposed patterns of traffic control,which will be required to address the 4-lane to 2-lane transition, and its impacts, immediately at the intersection of 55`h Avenue. 177
