Assistant City Engineer Steve Jankowski read the last portion of the law to answer Vice Chair Dehen's question and stated rural residential district existing in lawfully signed before August 1, 2009 continues to qualify as a rural residential district. No action taken. Case #8: MS4 Program Required Updates Civil Engineer Leonard Linton explained that the MPCA has asked that the City develop a plan for volume reduction to be ready by the end of May 2009. Councilmember McGlone asked how does the new dirt ordinance affect our numbers if we are going to slow infiltration and what does that do to this. City Engineer Tim Himmer responded it improves the use of water consumption as well as retains the moisture whether it is through rain or through irrigation. Public Works Director/Principal City Engineer Olson discussed simulating of pond and a pond has dead storage before the water discharges into the next water body or pipe and that is the 2 W' required for National Urban Runoff Protection. That is to protect the water quality. There is also water quantity which is flood control and you size your ponds making sure you have the ability to protect all the houses and we try to design our storm sewer system for a ten year level of service. The water quality side of things is the WMO requires what we require which is the NURPs standards and then there is the MPCA standard is only on a W' storm for water quality purpose. Another thing that goes along with this discussion is we are trying to encourage infiltration to take on some of that volume. Civil Engineer II Leonard Linton wanted to point out that the WMO is going through the same process and that we want to be in step with them. Staff is not asking for anything tonight, but just wanted to keep the Committee informed. No action taken. Case #9: Consider Request for a Priority Streetlight at the Intersection of Alpine Drive and Ute Street City Engineer Tim Himmeradvised that staff considered installing a street light back in November but due to cost conditions the project was delayed until spring. At that same meeting, it was discussed that the City may not be fulfilling its priority street policy on a high speed road at the intersection of Ute Street and Alpine Drive which meets our current policy. Staff is asking for authorization to install a street light at the corner of Ute Street and Alpine Drive. Motion by Mayor Ramsey, seconded by Councilmember McGlone to recommend to City Council to direct staff to install a street light at the corner of Ute Street and Alpine Drive.
