SEH <br />Building a Better World <br />iDeMliTifdilsr6, 2016 <br />Mr. Bruce Westby, PE <br />City Engineer <br />City of Ramsey <br />7550 Sunwood Drive NW <br />Ramsey, Minnesota 55303 <br />Dear Mr. Westby: <br />EVE <br />DEC 19 2016 <br />RE: Ramsey,Ynne 1a <br />Flashing Yellow Arrow Analysis <br />Armstrong Boulevard (CSAH 83) at <br />Sunwood Drive/147th Avenue <br />SEH No. RAMSY0000.00 <br />Short Elliott Hendrickson Inc. (SEIM appreciates the opportunity to submit this letter proposal to the City of <br />Ramsey for up -front analysis of the existing signal system at Armstrong Boulevard (CSAH 83) and Sunwood Drive <br />NW-147t Avenue NW with respect to potential implementation of flashing yellow left turn arrow operations. <br />Work required for this project will include a detailed site review of the signal system, review of existing signal plans <br />to determine costs and ability to convert the signal system to flashing yellow left turn arrow operations for each <br />approach, and final report preparation that will include the findings of our analysis as well as preliminary <br />construction costs to implement flashing yellow arrow operations. <br />For your information, SEH has significant experience in all aspects relating to traffic signals. This experience <br />includes study and analysis of the need for traffic signals, writing ICE --signal justification reports, design of new <br />traffic signal systems, modifications of existing traffic signal systems, Emergency Vehicle Preemption (EVP) <br />design, traffic signal timing and coordination, preparation of bid documents and construction inspection. Since 1978, <br />SEH staff members have designed more than 900 traffic signals and more than 300 additional EVP system designs. <br />A number of these designs have been within Anoka County and the City of Ramsey (including past design services <br />for traffic signal and EVP systems along CSAH 5, CSAH 57 and CSAH 116). SEH has also completed several <br />similar projects to address the potential for flashing yellow arrow operations, including for the Cities of Apple <br />Valley, Burnsville, Golden Valley and Woodbury and for Anoka and Washington Counties. <br />This letter proposal can be the basis for an agreement for the work on this project and all subsequent services. As <br />part of the project, we have put together the following work program for performing the services of this project. The <br />work program is fairly well defined based on anticipated cooperative efforts of SEH, the City of Ramsey, and the <br />Anoka County Highway Department for the complete project. The work program does, however, provide flexibility <br />to make the most efficient use of SEH and City staff. <br />Background <br />With the recent opening of the new Armstrong Boulevard bridge to the north (over Trunk Highway 10), area traffic <br />patterns will change significantly. With these changes, the City wishes to consider changes in the operation of the <br />signal system at Sunwood Drive NW 147t Avenue NW with respect to left turn phasing. This signal system is <br />located just south of the new Trunk Highway 10 East Ramps intersection and currently operates with protected left <br />Engineers I Architects Planners I Scientists <br />Short Elliott Hendrickson Inc., 3535 Vadnais Center Drive, St. Paul, MN 55110-5196 <br />SEH is 100% employee -owned I sehinc.com I 651.490.2000 I 800.325.2055 t 888.908.8166 fax <br />
