Memorandum <br />To: Streets and Utilities Committee Members <br />From: Design Team <br />Date:August 11, 2008 <br />Re: Consider Preliminary Survey For Area C <br /> File No.: 435-08132-0 <br />BACKGROUND <br />The typical schedule for a project in the Street and Utility Improvement Program (see attached) calls for the <br />Preliminary Survey to be performed in the autumn, two years before the construction is to take place. The <br />Preliminary Survey is the data collected by a survey crew to record the location of all the physical features of <br />the project site, existing elevations, etc – information that is necessary to prepare the Feasibility Report and <br />perform the design of the project. <br />For example, the Preliminary Survey for the project to be constructed in 2010 would be done this year, in <br />the autumn of 2008. The 2010 project is the area identified as Area B on the map of the overall Street and <br />Utility Improvement Program. A copy of the overall program map is attached for reference. The preliminary <br />survey work for Area B was already done in 2004, when that area was previously proposed as the 2005 <br />Street and Utility Improvement Project. <br />DISCUSSION <br />The potential Spring Creek Regional Storm Water Pond would also be located in Area B. The preferred <br />timing of the two projects would have the pond being constructed during the winter / spring before the <br />street project in Area B, to avoid construction equipment for the pond having to use the new streets. <br />However, with the adoption of new rules by Rice Creek Watershed District since 2005, and with the <br />revisions to the Mounds View raingarden / infiltration program, there is the possibility that the scope of the <br />Spring Creek Regional Pond could change, being reduced significantly or potentially even eliminated. <br />The answers to the questions on the Spring Creek Regional Pond won’t be known until the raingarden / <br />infiltration program is developed further, and can be investigated as it applies to the 2003 Street and Utility <br />Improvement Project area. In addition, discussion with Rice Creek Watershed District also needs to be held <br />concerning whether or not potential excess infiltration features in future projects could be applied as credits <br />towards the requirement of the Spring Creek Regional Pond.
