Mr. Michael Grochala September 2. 2015 Page 2 2. Complete Feasibility Level Design Work As part of this task, background information for the project area that is needed for this feasibility report will be gathered, reviewed, and analyzed along with other information gathered during previous studies. This effort will be focused on development of an outlet design for the trunk system that reflects the most cost effective feasible way for the outlet to be constructed. As part of this effort, an updated evaluation of the cost to provide more storm water storage and a smaller capacity pipe versus less storm water storage and larger capacity pipe will be undertaken along with the impact of these options on Peltier Lake. This analysis will be focused on only the outlet alternative that was selected as part of the previous sequencing analysis effort. Although, the feasibility report may discuss other options in a more general way, it is anticipated that only one alignment and design option will be formally evaluated as part of this work. Upon completion of this task, the recommended conveyance type (ie. open channel, or pipe), alignment, outlet pipe size, slope, and capacity, inlet locations and other appropriate design features will be developed for the trunk system that will serve the project area. A project memorandum will be provided at the completion of this task summarizing the results and justifying the design recommendation provided. Schedule and Cost It is anticipated that this work will take four weeks to complete at a cost of $13,352. Some of this work can be completed concurrently with the work outlined in Task 1. 3. Develop Preliminary Plan and Cost Estimate for Outlet A preliminary plan and profile for the outlet will be developed as part of this task to the extent necessary to verify the feasibility of the system, allow for quantity take offs to be undertaken, and develop an estimate of cost to complete the project. Schedule and Cost It is anticipated this work can be completed in three weeks, with some of it undertaken concurrently with the work completed on the previous tasks. The cost for this work is estimated at $5,864. 4. Meet with Stakeholders, Review Preliminary Plan and Cost Estimate As part of this task, it is anticipated that up to three meetings will be held to review the preliminary plan with stakeholders to obtain input into the design and cost estimate. Because the project will need to be acceptable to developers and property owners in the area, this communication effort will be extremely important and it's anticipated some changes to the plan may be necessary to address their concerns. Schedule and Cost It is estimated that this task will take three weeks to complete at a cost of $5,572. IPropoadsV'no LakesIL7R - mgrochala - NE Arca 061715.doc
