structures; 3) temporary drainage measures; 4) minor, localized detours/temporary roadways, and 5) temporary traffic signal control for multiple phases of the US -1 intersection, and to comply with FEC Railroad crossing requirements. The plans will be prepared at a reduced scale, 1 inch equal to 80 feet and be stacked two (2) roadway segments per plan sheet. It is estimated that a total of four (4) plan sheets will be prepared for "typical' MOT phasing/sequencing, both for advance warning signing and for traffic control features that will address CR-510/SR-510, in the "typical' areas of widening on either side of the US-1/SR-5 intersection. The intersection, and due to the complexity of the embankment and the need for a temporary detour and temporary traffic signalization, will require 1 inch equals 40 foot scale plans. This effort is estimated to include 16 plan sheets, and four (4) sheets for the temporary traffic signal plans. For the FEC Railroad crossing, the ENGINEER estimates four (4) sheets, and four (4) additional sheets for structural/embankment details, drainage requirements, signing and pavement markings, and business Way Finding signs. The total estimated MOT plans set is equal to 32 sheets. This effort/fee will be contained under the Lump Sum Components of the specific line item for MOT Plans, in "Section V — Compensation." O. Environmental Assessment/Regulatory Permitting Wetland Delineation AS DIRECTED B Y INDIAN RIVER COUNTY, THE COUNTY WILL PROVIDE THE ENGINEER WITH THE BELOW DESCRIBED SERVICES AS STIPULATED TO COMPLETE THIS PORTION OF WORK FOR THE HEREIN DESCRIBED PROJECT. 1. Assessment/Regulatory Permitting Wetland information is required to support the Project Development and Environmental study previously prepared. The COUNTY will be required to conduct a wetland delineation of the systems associated within the project limits and of the proposed retention pond sites. This effort will include: • Collection of existing or secondary data; • A field review of established wetland boundaries, in accordance with the criteria set forth in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands; • Preparation of a narrative, inclusive of the methodology, and graphical exhibits, denoting the wetland sites and boundaries; • And agency coordination and permitting to include Indian River County Planning Division, St. Johns River Water Management District; and the US Army Corps of Engineers.
