AMENDMENT NO.2 011,03_. ►_ ITS _� 1l ' ' §� ROADWAY IMPROVEMENTS AND DRAINAGE IMPROVEMENTS AT THE IRC LANDFILL EXHIBIT A SCOPE OF WORK PROJECT UNDERSTANDING Indian River County (County) Solid Waste Disposal District (SWDD) previously authorized Kimley-Horn and Associates (Consultant) to provide engineering services related to the paving of the yard waste drop-off area driveway and minor drainage improvements. A pre -application meeting with Indian River Farms Water Control District (IRFWCD) indicated that additional improvements will be required for the roadway crossing of the canal, including the full replacement of the culvert, additional drainage improvements, canal restoration and regrading of the entire northern bank of the canal within the project limits. These improvements will be required in order to obtain the necessary IRFWCD permits for the project. This amendment provides for additional design, survey and construction administration services associated with the required modifications. SCOPE OF SERVICES Task 1: Landfill Roadway Improvements Design review and pre -application meeting with Indian River Farms Water Control District (IRFWCD) indicated that the existing CMP culvert could not be extended under a paved road, or with utility crossings above it. Therefore, the existing CMP must be replaced with RCP To maximize cover and minimize the amount of required fill, the County has elected to proceed with elliptical RCP to replace the CMP. This requires minor redesign of the details for the crossing, as well as the addition of a maintenance of operations plan. The construction must take place such that access to the yard waste area is maintained at all times. This will be achieved via a temporary crossing to the east of the existing crossing. Additional sheets, details and notes will be required to convey the requirements to the contractor. This task has been amended to include the additional design services, as well as three coordination meetings with IRFWCD and additional services during construction to provide construction administration for the additional work area. Task 2: Drainage Improvements (Lump Sum) The pre -application meeting with IRFWCD also revealed that the cross section of the canal has eroded over time. IRFWCD is requiring that the County restore the cross section to match that up and downstream of the roadway crossing (i.e. narrowing of the top -of -bank to top -of -bank dimension), and restore the north side berm that prevents sheet flow drainage into the canal. This task has been amended to design the canal restoration, replace the north berm, and reconfigure the drainage in the yard waste drop off area to flow back to the drainage swale on the western perimeter (as originally designed). This amended task also includes contracting with a licensed Page] of 5
