Manteca upped the ante in its bid to land 500 jobs and generate as much as $6 million a year in room tax to support municipal services.A split Manteca City Council reversed itself Tuesday and essentially made the McKinley Avenue interchange on the 120 Bypass and the proposed nearby Great Wolf Resort, family entertainment center, and 100 acres of potential commercial development top municipal priorities.Councilman Steve DeBrum - who is part of the council committee negotiating with Great Wolf Resorts to bring a 600-room hotel, 75,000-square-foot indoor water park, and 30,000-square-foot conference center to Manteca just west of Costco on city owned land - indicated he expected the private sector project to move forward in January. Great Wolf would provide the 500 jobs plus room tax receipts.It is why DeBrum voted to reverse the council decision he supported just a month ago to basically suspend design work for the nearby McKinley Avenue interchange and send $2.8 million in federal dollars back to Washington, D.C.It would take about $20 million to convert McKinley into a full-blown interchange. It is the least expensive of six interchange projects Manteca is pondering with costs ranging from $25 million for Airport Way interchange modifications to over $100 million for a new interchange on Highway 99 south of Austin Road.What is riding on the proposed Great Wolf Resort is best framed not simply in the 500 year-round jobs and the fact that it is expected to draw other family entertainment-related businesses to locate in Manteca.
