MEMORANDUM L TO: ONO B MAYOR MORGAN AND OWN 0 ILMEMBERS FROM: Pi\ IN, TOWN MANAGER DATE: AP ,2000 RE: SPECIAL COUNCIL MEETING FOUNTAIN LAKE LINER REPLACEMENT PROJECT TIME AND PLACE: MONDAY,MAY 1, 2000 @ 5:00 P.M. COUNCIL CHAMBERS As you are all aware, the Mayor has called a Special Session for Monday night for the express purpose of considering the Fountain Park Lake liner replacement project. I anticipate the presentation to take approximately forty minutes, with Council discussion and possible action afterwards. For the last several months, our Fountain Lake liner consultants, Black & Veatch, have been working diligently to prepare a plan for this project. Attached to this memo is their detailed schedule showing both the time frames for each of the tasks and cost estimates for each task. I am recommending that the Town pay cash for this project. It is my belief that we can afford to do this. I have attached a new five-year financial plan to give Council an overview of how this will be accomplished. Please note the capital outlay line item for fiscal year 2000-2001 is in the amount of$3.6 million. Included in this number is a $1.8 million expenditure for this project. As you can see, even with this project included as a projected expense, our net surplus amounts remain healthy. In the revised projected five-year financial plan, I did not include the $1 million from the Los Arcos project, nor did I assume that impact fees would be enacted. Other assumptions are shown on the "Assumptions" page, also attached. I have asked representatives from the Sanitary District to be in attendance to answer questions that Council might have. I will be asking the Council for permission to move forward with this project and to authorize the expenditure necessary to accomplish this task. One final note, MCO has committed to paying the 12 percent as called for in the Downtown Development Agreement. _0) NC NN O CO IL = C cac C C1E1 C co 4. C C y 4.E.
