Flashing beacons include beacons mounted on span wire directly over the intersection or <br /> beacons mounted on pedestals above the advanced warning signs, Both flashing beacon <br /> systems have advantages and disadvantages. Overhead beacons may be confused with <br /> flashing red signals or may distract the motorist from the roadway signing, but they aid the <br /> motorist in locating the intersection of hazard. Pedestal mounted beacons help draw <br /> attention to the advanced warning signs but do not help locate the intersection or a crosswalk <br /> somewhere ahead of the flashing beacon. <br /> The advanced pedestal mounted flasher can be installed at this intersection, for a cost ranging <br /> from 56,000 - 512,000. These costs are based on information provided by the Centerville <br /> School District No. 12. These alternatives would include using a variety of trenching and <br /> existing wood poles. In addition, there is no good location to locate the pedestal pole for <br /> eastbound CSAH 14. This is due to the large driveway and parking lot adjacent to the <br /> roadway on the south side of CSAH 14. <br /> Overhead mounted flashers would require a substantial amount of work at the intersection <br /> in order to mount the flashing beacon at the proper height. This is a result of the significant <br /> number of overhead power and cable t.v. lines across and in this intersection. The estimated <br /> cost to provide a overhead mounted signal would range from $7,000415,000 depending on <br /> the need for relocating existing overhead power lines. <br /> 2. Signing 1 Striping Improvements <br /> This alternative would involve re- striping the crosswalk and providing additional or <br /> improved signing of the crosswalk. Visibility of the advanced warning signs and crosswalk <br /> markings is imperative for drivers approaching eastbound and westbound on CSAH 14 <br /> (Main Street), This alternative would provide for replacing the existing pedestrian crossing <br /> signs with the strong fluorescent yellow -green signs and re- striping the crosswalk with high <br /> intensity pavement markings. This improvement would be a relatively low cost <br /> improvement. The cost for this alternative would range from 51,00042,000, assuming <br /> installation by County maintenance crews. In addition, the recommendations of the Anoka <br /> County Study of January 7, 1998 should be carried out and CSAH 14 right -of -way be cleared <br /> to the greatest extent possible to improve the visibility of the crossing. <br /> 3. Relocating Crossing <br /> This alternative would relocate the existing crosswalk from Progress Road to the intersection <br /> of CSAH 21 one block west. Currently, this intersection is a 4 -way stop sign controlled <br /> intersection. By relocating the crosswalk to this intersection, the existing stop sign control <br /> can be used for the safety of pedestrians. However, some roadway improvements may be <br /> required to accommodate the school crossings. This would include the addition of pedestrian <br /> curb ramps for the crossing as well as sidewalk installation. This alternative provides for the <br /> safest situation for pedestrian crossing CSAH 14 (Main Street). The estimated cost to <br /> provide a relocated crossing would depend on the amount of sidewalk installed. <br /> School Crossing Study <br /> Anoka County <br /> WSB Project No. 1044.08 Page 5 <br />
