Paul Emeott, Mayor l May 11, 2007 Page 2 • Provide traffic memo on findings. B. Eastern Hansen Parcel • Review CR E access requirements with Ramsey County and determine number of access points for parcel. • Investigate potential for signal at CR E/International Drive intersection; use available traffic count data and determine expected trip generation for parcel. • Assist with roadway layouts for parcel. Provide advantages/disadvantages of roadway connection between Eastern and Western parcels and revising private driveway that currently divides Eastern and Western parcels. Provide traffic memo on findings. C. Hoffman Corners • Review TH 61 access requirements with Mn/DOT, CR E access requirements with Ramsey County, and possible connection to Hoffman Road with Vadnais Heights. Determine number of access points for parcel. • Determine expected trip generation for parcel. • Assist with roadway layouts for parcel. • Provide traffic memo on findings. Tasks — Water Supply A. Hydrant Flow Testing on Vadnais Heights Water System The City of Vadnais Heights would like Gem Lake to perform hydrant flow testing near the locations identified for development, where connections to the Vadnais Heights water system are anticipated. The information obtained in this process will assist in calibration of the water distribution system model (see Section B below), and will help the City to determine the amount of water that is available for fire protection activities in that area. SEH proposes to conduct two hydrant flow tests, one near County Road E and International Drive, and one near Highway 61 and Wolters Boulevard. This task will require the cooperation of Vadnais Heights City Staff. B. Water Model Calibration Information from the hydrant flow tests performed in Section A will be used to adjust the Vadnais Heights water distribution system model to reflect results obtained in the field. This will improve the accuracy of water system modeling results that will be used to make recommendations for connection locations to serve the proposed developments. C. Water System Scenario Modeling With permission from the City of Vadnais Heights, their water distribution system model will be used to calculate the hydraulic properties of the water system as it is expanded to serve the proposed development areas. The City of Gem Lake will need to request permission in writing from the City of Vadnais Heights to use this model. SEH proposes to model two alternative scenarios for each parcel that is planned for development, and to present the results from these modeling scenarios. Scenarios modeled will examine system pressures, available fire flow rates, and pipe velocities under varying demand conditions on the system.
