EXHIBIT A - SCOPE OF WORK As per our coordination, we are hereby submitting our proposal to provide additional professional services for the above subject project. This proposal shall be considered an addendum to the original executed Work Order 10, IRC -1908 Jackie Robinson Training Complex Walking Trail, and all contract conditions shall be part of this addendum. Pursuant to the St. Johns River Water Management District's (SJRWMD) denial of a letter modification as described under the original Work Order Scope, and now requiring the project to obtain a permit modification to the existing permit No. 40-061-123418-1, additional professional services for the below items will be required for completion of the project. Addressing these were not anticipated or included in the original scope of work. The additional requested scope of services will include addressing the comments listed in the comment letter received from on July 13, 2020 and is itemized below. St. Johns River Water Management District July 13, 2020 RAI: 1. As requested previously in comment 1 of the District's April 10, 2020 RAI letter, the design proposes runoff from the project site to be directed to the existing wet detention pond east of the site known as Pond 100. a. Please provide calculations and supporting information demonstrating that the wet detention system has sufficient excess capacity to provide treatment in accordance with Section 8.0, A.H. Vol II. b. Provide a recent site inspection report of the existing pond demonstrating that it is functioning as designed and permitted. [62-330.301(1)(e)(i), F.A.C.; 8.0, A.H. Vol 11] 2. As indicated previously in comment 3 of the District's April 10, 2020 RAI letter, the proposed project discharges to the Indian River Lagoon, which is deemed impaired for Nitrogen and Phosphorus. Please demonstrate the post -development annualized mass nutrient load discharged from the site is less than the pre -development site loading. Alternatively, demonstrate that with the new proposed development the total amount of impervious area in the Pond 100 basin is within the previously permitted design assumptions. [62-330.301(1)(e), F.A.C.] 3. As requested previously in comment 4 of the District's April 10, 2020 RAI letter, please demonstrate that the existing wet detention pond to which your project will discharge has sufficient excess capacity to attenuate runoff from the proposed site for the mean annual and 25-year/24-hour storm events. Alternatively, demonstrate that with the new proposed development the total amount of impervious area in the Pond 100 basin is within the previously permitted design assumptions. [62-330.301(1)(a)(b)(c), F.A.C.; 3.2, A.H. Vol II] 4. The RAI response received on June 18, 2020 referenced the information requested in the District April 10, 2020 RAI comment 5 was already provided. This information has not yet been received. Therefore, please include on the plans, the total acreage of surface waters (the plans show the surface waters as Indian River Farm Water Control District Sub -lateral A-3 Canal) within the project area and the total acreage of surface water impacts from the installation of the drainage culvert. In addition, please amend the plan detail sheets to show the surface water boundaries
