IRC Work Order No. 1— Exhibit "A" <br />49th Street/USI Intersection Improvements <br />Page 2 of 5 <br />signage elements, and sidewalks. The Conceptual Plans shall be submitted to Indian River <br />County Engineering for review and acceptance prior to our proceeding with additional design <br />services. <br />It is our intent to design the 49th Street 3 -Lane section (Old Dixie to U.S. Highway # 1) / turn <br />lane improvements centered on the quarter -section line. We expect the Old Dixie Highway turn <br />lanes to be accomplished via a west side widening. In order to be eligible for a SJRWMD <br />Permit Exemption, the turn lane improvements will be designed without the need for curbing and <br />storm conveyance piping to eliminate the need for treatment facilities (which might necessitate <br />the County purchasing stormwater treatment tracts). <br />During this task, we will coordinate with Jill Grimaldi of CDM Smith, the County's liaison for the <br />"All Aboard Florida" (AAF) Railroad project. It is understood our Concept Plans will be submitted <br />by CDM to the Florida East Coast Railroad (FECRR) in order that they may plan and design for <br />the expanded roadway improvements to be constructed with this project, as well as their <br />planned calming devices. We will make adjustments to the Conceptual Plans based on <br />feedback received by Indian River County via CDM Smith. <br />Preliminary Construction Plans <br />Preparation of Preliminary Plans for the planned project improvements to include: <br />Title Sheet <br />Construction Notes <br />Summary of Pay Items <br />1� Roadway Improvements Plan Views <br />Roadway Profile Views (as Necessary) <br />Cross-sections <br />Striping & Signage Plans <br />Construction Details <br />The Preliminary Plans shall be prepared based on the following design criteria: <br />Ex.
