EXHIBITA • Locate " specimen" trees within the limits of construction for use in preparing a tree mitigation plan . Utility Locates . • Engineer has identified 22 potential conflicts with existing utility lines (water mains) and proposed stormwater pipes . In order to design appropriate resolutions to these conflicts , the exact locations (horizontal and vertical) of the existing utility lines must be determined . • Engineer will locate and expose the existing utility lines (water mains) at 22 potential conflict points . • Engineer will survey the exact locations of the existing utility lines at those points . • Engineer will import the new survey data into the project drawing file for analysis with the proposed stormwater system . • Engineer will incorporate appropriate design solutions into the project plans as part of the basic scope of services provided by the original Professional Engineering Services Agreement . Drainage Design and Pertnitting : • Engineer will coordinate with County staff to select existing , unpermitted , paved roadway segment(s) to provide compensating treatment volume for the portions of the proposed 4"' Street and 12 "' Street improvements that directly discharge to IRFWCD sub -lateral canals . • Engineer will design new drainage system( s) to provide treatment and attenuation of stormwater runoff for the selected existing paved roadway segment( s) . • Engineer will design the new drainage system(s) to meet current SJRWMD rules . • Engineer will prepare new plan elements , including control sheets , plan and profile sheets , cross - sections , and drainage structure details . • Engineer will revise existing plan elements including drainage structures table and tabulation of quantities , accordingly . • Engineer will prepare a revised Stormwater Management Calculations Report which will contain detailed calculations and stormwater computer models based on the additional drainage basin areas and conveyance systems . • Engineer will prepare and submit permit applications for new SJRWMD and IRFWCD permits . Deliverables : Deliverables to Indian River County shall include an updated topographic survey of the project area , a legal sketch and description of the new pond site , a 90% design submittal and a 100% final submittal . The 90% design plans will include copies of the permit application forms and exhibits , as submitted to the permitting agencies . Upon. receipt of the permits and of the County ' s final review comments , the Engineer will prepare and submit the 100% final plans for use in bidding and construction of the project. Engineer will provide three signed and sealed 8 . 5 "x ] 4 " sets of the legal sketch and description for acquisition purposes . Engineer will provide one 11 "x17 " set of the updated topographic survey and an electronic copy in AutoCAD 2009 format . Engineer will provide one 11 "x17 " set of each of the design plans . The Engineer will provide an electronic copy in AutoCAD 2009 format with the 100% design submittal . Assumptions : In developing this proposal , the following assumptions have been made and deviation from these assumptions may require additional expenditures on behalf of the County to the Engineer : • The County will acquire a 3facre pond site along the north side of 4t" Street, between 66t" Ave and 74"' Ave , which is suitable for a stand-alone wet detention stormwater management system to collect and treat runoff from a sufficient portion of 4th Street to compensate for the uncollected drainage basins within the current project area . 5e,rviijg 14lori�la Page 2 of 3 Since 1911
