March 1, 2004 File: 803950J -0325 Mr. Joel Hanson City of Little Canada 515 Little Canada Road Little Canada, MN 55117 R. Green Company RE: POSSIBLE STREET EXTENSION Dear Mr. Hanson: As requested, we have reviewed the area between LaBore Road and Gervais Lake east of Arcade Street to determine the possibility of providing a street extension off Arcade Street for access to the undeveloped areas south of the homes along LaBore Road. The factors affecting our recommendation include the existing topography of the area, the placement of the existing homes along Arcade Street and LaBore Road, and the existing wetland locations throughout the site. Attached is an exhibit obtained from the Ramsey County Washington Watershed's GIS database. The exhibit is an aerial photo of the area with the existing topography and wetland boundaries superimposed. The watershed has verified the relative accuracy of the wetland boundary as shown on the aerial, indicated by the dark purple line. It should be noted that this area was preliminarily reviewed in the past to determine a possible street connection. At that time it was thought that a road could be extended from Arcade Street along the rear of the homes parallel with LaBore Road to provide access to the undeveloped area behind the homes for development. The old layout is attached. When the existing topography and wetland boundary are taken into account, this proposed layout appears to be less desirable than originally anticipated. The existing topography west of Arcade Street indicates vertical relief of approximately 40 feet between the rear of the homes along LaBore Road to the back lot line elevations. In addition, the wetland edge is only approximately 50 feet south of the first three homes east of Arcade Street. The existing topography would require substantial fill through this area and significant wetland impacts to complete a connection to Arcade Street. It also appears that no additional developable lots would be created until approximately 500 to 600 feet east of Arcade Street. Therefore, it is our recommendation that the street to access this area not be extended from Arcade Street. Upon review of the topography, existing home locations, and the wetland boundaries, we have proposed a new possible street alignment thru this area. The proposed alignment is shown in red. It is proposed that a connection to Labore Road be made west of the house at 2966 Labore Road. The street would extend to the south and east and connect to Beam Avenue.
