r DEC 31980 During the workshop session, the proposed concepts were outlined and based upon the design will proceed in accordance with the Outline Specifications. Boa 45 PAGA48 roadway alignment and drainage resulting discussions, final attached Design Development E.S.&E. will again touch base with the agencies involved in order to receive comments concerning the proposed drainage box culverts and roadway crossdrains and any subsequent problems that may effect the permit application process. As part of the permit application, exhibits showing each of the proposed box culverts, roadway crossdrains and bridge, along with design data, must be submitted. For this reason, a timely resolution of the legal concern of tidal flushing to the East impounded areas due to the two proposed crossdrains (Station 374 + DO and 386 + 30)is ir,rperative. Enclosed you will find a print of the Drainage flap with the proposed drainage as outlined in the Design Development Outline Specifications. I trust that this will aid in your percepticn of the Project at this point in time. If we may be of any additional assistance, please give John Deamud or myself a call. Sincerely, REYNOLDS, SMITH AND HILLS Stephen L. Kincaid, P.E. Design Engineer DESIGN DEVELOPMENT OUTLINE SPECIFICATIO14S INDIAN RIVER BOULEVARD EXTENSION SITEWORK: Clear and grub to prepare the site for placement of the bridge and paved roadway. Strip area within limits of construction of all vegetation and trees and soils contain- ing roots to approximately six inches or more where requ i rf J. De -muck areas as required in accordance with the recocrurend,;- tions of the "Soils" Engineering Report. Compact arca and place necessary fill, compacting in layers, in the desitv,! elevations and achieve the specified density. DRAINAGE: Provide a bridge over the stain Canal consisting of a 1-i- foot span with a minimum 14 feet clearance ,above M.H.U. elevation of 2.215 feet. Provide a double 10' x 5' box culvert in the North Canal and a double 9' x 4' box cuivt't-t in the canal adjacent to Barber Avenue crossirly under Indian River Boulevard. In addition to the Bridge and L,C.\ culverts provide additional crossdrainage under the roadt.,.Y at Stations 365 4 00 (±), 375 + 00 (1) and 336 + 35 (f� The structures provide adequate conveyance area in the waterways for existing and future flow conditions to prevent flooding during design storm events. In additio,", tidal flushing is improved considerably to areas currentiv receiving little or no tidal flushing. Roadway pavement run-off will' b4� directed to the East and pi cl:ed up by parallel Swale ditches within the roadway right-of-wav and directed to nearest existing waterway. PAVING: The roadway shall be twenty-four (24) feet of pavement .:it.', a ten (10) feet stabilized shoulder each side. Side slore•, shall typically be 6:1 with variances as required to min kii:: right of way requirements. All paved areas shall be aspha:: concrete. Finished pavement shall be striped and required safety appurtenances will be provided in accordance with current County and State design criteria. RE71W 11/12/80
