Introduction The Minnesota Department of Transportation (MNDOT) Unweave the Weave Project includes the replacement of the Edgerton Street Bridge over I -694. As part of this bridge replacement, the bridge will be raised approximately 4 %2 feet, which will require the approaches to the bridge along Edgerton Street and County Road D to also be raised. Ramsey County Public Works Department who owns and maintains these roads has determined that the approaches to the new bridge should be constructed as an urban street section, (paved road with concrete curb and gutter) as part of this MNDOT project. This will allow the County to start any future reconstruction of these two roads at points away from the intersection, thus reducing future costs and the impact to traffic at this intersection. In addition, to minimize, future costs to the City of Little Canada and its residents, the City of Little Canada staff has determined that it would be the most economical time to also extend and /or improve any of our utilities (water, sanitary sewer, and storm sewer) within the approach construction zone. Scope Street Both Edgerton Street and County Road D are County Roads and are currently built to rural standards with roadside ditches. Ramsey County Public Works has indicated they are not reconstructing County Roads to rural standards if they are in urban areas. Based on this, Ramsey County Public Works indicated that in the future, both Edgerton Street and County Road D will be reconstructed to urban standards. Therefore, any improvements to these roads at this time should also be done to urban standards. Thus, both Edgerton Street and County Road D approaches to the new bridge will include a new bituminous surface, concrete curb and gutter, and a buried stone sewer system as shown on the attached drawings. Stoma Sewer The storm sewer system design for the Edgerton Street Bridge replacement project includes sufficient size to accomidate future storm water that may be directed to this area. This includes the storm water that would need to be drained from the future reconstruction of both Edgerton Street and County Road D outside the area of the bridge approach reconstruction zones. Sanitary Sewer A City of Little Canada sanitary sewer system currently exists within all the Edgerton Street and County Road D approach construction zones and does not need to be repaired nor replaced. Water Main The City of Little Canada currently has water main along Edgerton Street and County Road D east of Edgerton Street. No problems have been experienced with this system. There is no City of Little Canada water main along County Road D west of Edgerton Street within the County Road D approach construction zone. As a result the City of Little Canada is proposing to extend the Cities water main along County Road D west of Edgerton Street as shown on the attached drawing. \GregS\ Water \Feasibility Study County Road D Water Main.doc -3-
