EXHIBIT A - SCOPE OF WORK It is understood the COUNTY desires to construct a new Public Road (11th Drive) from the south property line of the Harbor Bluffs parcel to 37th Street. It is also understood the COUNTY desires to re- align a portion of existing 11th Drive immediately south of 37th Street and to carry the improvement through the 36th Court 4 -way stop intersection to approximately 150 feet south. In addition, the COUNTY also desires to improve the existing intersection at 11th Drive and 37th Street by installing a new mast arm traffic signal with pedestrian crosswalks, curb ramps, sidewalk ramps with landings and the associated signage and miscellaneous pavement markings, as needed. Furthermore, we understand the COUNTY desires a safety upgrade to the existing Go -Line bus stops that are presently located in the 37th Street grassed rights-of-way, by installing separate turn -outs that will allow for the busses to pull off the 37th Street east/west travel lanes to load and off-load passengers. In order to provide enough area for the new bus turn -outs, portions of the existing Swale located in the southern ROW of 37th street will require culverting. Finally, we understand the COUNTY must provide sidewalk connections to the Cleveland Clinic Indian River Hospital from the 11th Drive roadway. Through preliminary consultation with County staff, this proposal assumes that the drainage for the north portion of the 11th Drive Public Road improvements will be collected utilizing a curb and gutter system with an underground piping network. The design will provide for the stormwater to be collected and conveyed to the north via an underground piping network to a new dry pond that will be located on the north side of the project area. The CONSULTANT assumes that the roadway improvements associated with the areas south of 37th Street will be permitted to continue to drain to the existing Indian River Hospital District's master drainage system through the network of pipes and existing swales and will not require further treatment ponds or modifications to their existing wet ponds. Project survey will be provided by Indian River County, inclusive of any additional utility and underground infrastructure that may be required for design and that is not presently depicted on the County's topographical survey for this location. COUNTY shall conduct Title Search on the SW corner of 37th Street & 11th Drive for the existing utilities equipment / services located in this area. CONSULTANT will work with County staff and the franchise utility operators for this area to identify any surface or subsurface utility information needed in order to provide for a proper design. The CONSULTANT proposes to provide the COUNTY with the necessary design plans and engineering to complete the below detailed scope of work associated with the 11th Drive and 37th Street Roadway and Intersection improvements project. A. 11th Drive Roadway Improvements 1. Task 1- Geotechnical Investigation A soils investigation conducting (5) Augers with HCP every 200 ft on the south side of 37th Street along existing 11th Drive, (8) Augers with HCP every 100 ft on the north side of 27th Street for the new section of roadway, 4 SPTs (1 for each Mast Arm Location) to a depth of 35ft and one Auger to a depth of 10ft and (3) Shelby Tube samples in the proposed new dry pond location for the horizontal and vertical permeability tests. CONSULTANT will coordinate above with the geotechnical firm and all testing shall be in accordance with ASTM D — 1586.
