JANONIS DEPUTY DIRECTOR OF PUBLIC WORKS DECEMBER 30, 2003 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PHASE 2 STORM SEWER SURVEY CONTRACT EXTENSION On October 16, 2001, the Village Board awarded a contract to Stanley Consultants, Inc. of Chicago, Illinois in the amount of $1261790 to help staff comply with the Clean Water Act's National Pollutant Discharge Elimination System Phase 2 requirements. The scope of this contract included existing ordinance reviews, best management practices recommendations, permit application assistance, a storm sewer survey and mapping project,' and assistance filing a notice of intent (NOI) to join the State of Illinois general NPDES Phase 2 permit. The ordinance reviews, best management practices development, and permit application tasks are complete and were presented to the Village Board at a February 2003 Committee of the Whole meeting. The NOI was filed with IF:PA in July 2003. You may recall that the NOI required the Village to make certain on-going commitments to pollution prevention activities. One of these commitments was a promise to complete mapping the separate storm sewer system by the end of 2006. Stanley started field data collection in October 2001. The Village Board made subsequent contract extension awards for continuing this work in 2002 and 2003. To date, they have surveyed and mapped approximately 51 miles of separate storm sewers. Staff now estimates that approximately 39 miles of separate storm sewers remain. The attached map depicts Stanley's progress to date. It is significant to note that a large portion of the Village is not included in this project. The oldest parts of the Village, generally those around the geographic center, are served by combined sewer systems. Combined sewer systems are not being surveyed as part of this project. Proposal Pursuant to staff request, Stanley has submitted a proposal to extend their existing contract and continue storm sewer survey and mapping work. Specifically, Stanley proposes to survey and map additional storm sewer at the rate of $3,620 per mile for a cost not to exceed $75,000. They propose to commence this work immediately and complete all fieldwork before the tree canopy is reestablished in the spring. age 2 of 2 NPDES Phase 2 Storm Sewer Survey Contract Extension December 30, 2003 Discussion Stanley proposes to continue survey and mapping work at a rate that is approximately $20 per mile higher than the work performed in 2003. This fee represents a 0.01% rate increase and seems to be a reasonable accommodation considering nominal increases in personnel and operating costs. Stanley has performed extremely well during the initial phases of this project. Their personnel have proven to be technically proficient, courteous to residents, highly motivated, and very productive. In addition, they have refined an innovative and effective methodology for generating computer maps of unmapped networks using only spatial coordinates and limited attribute data. Recommendation I recommend accepting the proposal from Stanley Consultants, Incorporated of Chicago, Illinois to continue stor~m sewer survey and mapping work in conjunction with the Village's NPDES Phase 2 compliance efforts and extend their existing contract for a cost not to exceed $75,000. Funds for this proposed expenditure are available in account number 5907704-540582 ($75,000)on page 301 of the proposed 2004 budget. Sean P. Dorsey I concur. Glen R.
