INTRODUCTION ' 2.1 Authorization � , On December 21, 2004,the Rosemount City Council authorized the preparation of a Feasibility Report to address development-related infrastructure costs attributed to the Connemara Crossing ' development. The Connemara Crossing Street and Utility Improvements and Appurtenant Work project has been designated as City Project No. 391. ' The Connemara.Crossing developer,Basic Builders,Inc.,will be funding all costs associated with this project. ' 2.2 Scope This report addresses the construction of street and utility improvements necessary for the ' development of the Connemara Crossing residential development located on the southwest quadrant of the Connemara Trail and Biscayne Ayenue intersection. The proposed improvements include construction of streets, lateral sanitary sewer,watermain, and storm sewer ' systems.

GENERAL BACKGROUND ' 3.1 Project Location ' The project is a proposed 44-unit townhouse development to be located on a 13.8$-acre parceL The tract is located on the southwest quadrant of the Connemara Trail and Biscayne Avenue intersection. The Canadian Pacific Railroad has a raikoad spur line along the west side of the ' property. The State of Minnesota,Department of Military Affairs owns the property to the immediate south of the development for utilization by the Minnesota National Guard as a , maintenance facility. A map showing the location of the project can be found in Figure 1 of A�pendix A. � 3.2 Ezisting Conditions The developer has already preliminarily graded the majority of the existing land. Prior to ' grading, the area consisted of an open field,with some small trees and brush located along the Canadian Pacific Railroad right-of-way, as well as adjacent to Connemaxa Trail. The proposed development will save most of the trees along the Canadian Pacific Railroad tracks,but will ' remove said trees adjacent to Connemara Trail for grading and drainage purposes. There is no current access constructed to the property from any adjacent roadways. Due to the ' topography,temporary and permanent access will be obtained off of Biscayne Avenue, approximately 550 feet south of Connemara TraiL ' The terrain in the project area is generally sloped to the west,toward the Canadian Pacific Railroad right-of-way. Storm sewer installed along Connemara Trail in 2003 was sized to include future development on this site, and to accept storm water from the site to the regional ' storm water pond located due north across Connemara Trail. The project area is currently served by the Rosemount West Water System. A 16-inch DIP , watermain was constructed along Biscayne Avenue in 2003,with two separate 8-inch stubs provided to service the proposed development site. ' An 8-inch PVC sanitary sewer stub to service the proposed development site was installed along Connemara Trail during the construction of the Brockway Draw sanitary sewer. It is deep enough to provide gravity service to al144 proposed lots within the praposed development. ' There are overhead(aerial)private utilities located along the south property line of the proposed development. These utilities should not affect the construction of any of the proposed ' improvements.
