actual costs incurred . The County also requested that CDM subcontract with Entrix directly to assist in coordinating efforts with the County' s environmental representative and FWS . A proposal was received from Entrix totaling $4,200 . The Outside Professionals budget was amended (attached) to include this $4,200 increase . TASK 2 . 0 SITING OF WELL CDM began by relying on the existing groundwater model for siting of the well. Discussions with SJRWMD and a review of the consumptive use permitting regulations determined that the well location could shift so long as it remained within 200 feet of the modeled location, without requiring additional modeling to support such a move . Any relocation beyond the 200 foot radius would require the modeling to be revised . CDM worked with Parks and Recreation staff, as well as the Utilities Department and FWS to shift the well further south within the 200 foot radius . This move allows for less transmission piping to connect the new well to the system, and shifts the well site further away from the conservation area . CDM revised the siting maps accordingly for use in discussion at the various aforementioned meetings . These efforts have already been completed, as it was necessary to shift the well location while designing the sanitary sewer line to allow for proper separation of water and. sewer system components . While costs for these revisions are minimal, they were not anticipated during preparation of the original scope of services . CDM does not anticipate additional efforts for this task . CDM was able to perform the additional efforts for this task within the original budget. No additional funds are being requested . TASK 3. 0 WELL NO. 7 DESIGN Subtask 3 . 1 Well Construction Details No changes were made or are anticipated to be made to the design of the production well . Subtask 3 . 2 Wellhead and Appurtenances No changes were made or are anticipated to be made to the design of the wellhead or appurtenances . Subtask 3 . 3 Batu Water Piping CDM revised the County' s original requested pipeline route (around the north side of the ball fields) to shorten the length of piping needed by connecting to the existing 18-inch line at Well No . 6 . These additional services have already been completed as part of the expedited work associated with the sanitary sewer line (necessary to insure proper separation when designing the sanitary line) . The labor estimate provided in the attached budget reflects actual costs incurred . While costs for these revisions are minimal , they were not anticipated during preparation of the original scope of services . Subtask 3 . 4 Sanitary,/ Sewer Line Design As mentioned above, the County requested that CDM include design services for the proposed sanitary sewer line for the park' s new restroom facility as part of this project. This is a new subtask, and was not accounted for in the original scope of services (resulted from the kick-off meeting with staff) . The sanitary sewer line was to connect the proposed restroom to the lift station located at the southwest corner of 5th Street SW and 20th Avenue SW . The County requested that the design avoid the conservation area wherever possible, tie into the lift station via gravity flow, and be constructed via horizontal directional drill (HDD) . cm 2 j12756. doc
