Staff approval of updated plans addressing comments outlined in the staff comment letter dated January 15, 2020. 2. The CUP will not be recorded until impacted property owners agree to required easement or right-of-way transactions. Background/Discussion The applicant is proposing to modify and expand the parking area located between Elk River High School, the multi -purpose facility, and VandenBerge Middle School. Additionally, the proposal relocates the current signal from its location at Lions Park Drive to the new driveway location aligning with the west entrance of Central Lutheran Church. The stormwater pond in the current parking lot is relocated to an expanded pond in Lions Park. Comprehensive Plan The Comprehensive Plan guides the area for Public/Institutional uses, which is consistent with the proposed development Site Plan Figure I Updated site plans remove the existing stormwater pond to expand the parking area. The lot has 2 to 3 one-way drive lanes around the perimeter, improving safety by separating the parking area from the bulk of vehicular traffic. The outside lane is designed for drop-off/pick-up at the high school and the multi- purpose facility. The parking area includes two raised sidewalks to separate pedestrian traffic from the cars. The areas where pedestrians cross traffic lanes include raised speed tables to slow traffic. The Elk River Vision A welcoming community with revolutionary and spirited resourcefulness, exceptional p Q w E H E U e T service, and community engagement that encourages and inspires prosperity ,� g /� However, the most significant change to the parking lot is the relocation of the traffic signal from Lions Park Drive to the west. The new signal aligns with the west entrance to Central Lutheran Church and removes the two driveways currently used for high school traffic. A non -signaled right -turn lane for west- bound School Street traffic allows drivers to enter the drop-off/circulation lane prior to the signal, leaving most traffic at the signal for east -bound traffic. Pushing both entrances to the west will also reduce the likelihood of traffic back-ups onto School Street during the busiest pick-up/drop-off times as the queuing lane is much longer. Driveway access to VandenBerge is now condensed to one location. The proposed plan reduced the number of driveways serving the school district along School Street and should improve safety and mobility during the morning and afternoon pick-up/drop-off times. Engineering and Utilities There has already been significant utility work in the area to relocate the stormwater pond, expand the existing pond at Lion's Park, and facilitate development of the multi -purpose facility on the north end of the parking lot. This work will continue as the school district completes their parking lot improvements.

Please review the following comments and provide a response letter. Any unaddressed comments will be incorporated into conditions of approval. 1. Three traffic lanes providing drop-off/pick-up on the west side of the building has the potential to create a hazardous situation. What is the plan to ensure pedestrian safety during these busy times (which lanes will be for drop-off/pick-up, staffing to direct traffic, etc)? 2. Are there plans for additional signage to show which lanes are for drop-offs and which lanes will be through lanes? Have additional speed tables or other traffic calming measures been considered to ensure vehicles do not move at an unsafe speed along the perimeters? 3. Please delineate the parking areas that will be reserved for the multi -purpose center during school hours. 4. What plans have been put in place to accommodate employee parking for the multi -purpose center, deliveries, maintenance services, visiting team busses, emergency vehicle circulation etc? Please describe how these user groups will be accommodated within the proposed plan. 5. Please respond to the following public safety concerns as they relate to relocation of the traffic signal. a. Residents and students from 1001 School St (apartment complex), 1105 Lions Park Drive (apartment complex) and Lions Park use the current intersection to safely cross back and forth to the School across a 4 lane, undivided primary roadway. 13065 Orono Parkway Elk River, MN 55330 763.635.1000 INATUREE] ElkRiverMN.gov i. Residents and students from 1001 School St and Lions Park will most likely continue to cross there after the semaphore is moved further west from their building. Human nature is not to walk a block west, cross at a controlled intersection, then walk a block back east to access the school when it is directly across the road from their house or park. This is why there is a "jaywalking" statute. This creates a danger to the residents and students trying to navigate 4 lanes of traffic, even with a flashing crosswalk. It also creates a danger to 4 lanes of vehicular traffic while trying to avoid the students by sudden stops, swerving, or hitting a student. This is now more of a problem as you have a semaphore controlled intersection and a flashing light crosswalk within a few hundred feet of each other. The motorists travelling through are now navigating two pedestrian crossing areas in close proximity. ii. Residents and students of 1105 Lions Park Drive currently cross at the semaphore at Lions Park Dr. If the semaphore is moved to the west entrance of Central Lutheran, those pedestrians will more than likely walk straight north from their building and cut through the west lot of Central Lutheran Church. This presents problems with potential trespassing issues and pedestrians walking through a busy parking lot where staff and customers of the daycare park and drop off/pick up children. It could also interfere with vehicular traffic entering and exiting the church for a funeral. iii. Student athletes and coaches will now have to cross School St to access Lions Park and the softball fields, and then cross back. These practices generally take place after school, during rush hour times. They will most likely be crossing at the flashing intersection at Lions Park Drive, not the safer option of the semaphore controlled crossing further west, and this is dangerous for the same reasons listed above. b. Residents of 1001 School St, 1105 Lions Park Dr, and visitors to Lions Park currently have a semaphore controlled intersection to safely enter and exit their residences, and the park, from a 4 lane, undivided roadway. If the semaphore is moved to the west, they will lose that safety. c. Moving the semaphore controlled intersection further west, and close to Proctor Av, will have a direct impact on traffic flow on Proctor Av. Proctor Av is an undivided, 4 lane, major north/south roadway connecting the northern half of Elk River and Sherburne county to the schools, parks, Hwy 10 and Hwy 169. The intersection of Proctor Av and School St is one of the busiest intersections in town during peak morning and evening school times and rush hour. It will now see more congestion as there is much less room for staging on School St, which will in turn back up both north and southbound Proctor Av. d. The shorter staging distance on School St from the proposed location of the semaphore to Proctor Av will have a direct impact on vehicular traffic of residents entering and exiting their residences in 5 apartment buildings, 1109, 1111, 1115, 1175 and 1179 School St. Their only access is off of School St in the new, shorter, staging area. 6. Please describe how the parking lot configuration complies with MN State Fire Code chapter 5 and appendix D. 7. Have there been any considerations for adding electric vehicle charging stations or adding conduit that could be utilized at a later date? 8. It is understood that the new lighting system utilizes smart LED technology to manage the light levels at different times of the night. Automatic adjustments to the light levels may occasionally result in situations where the city standards are not met but would be when motion is detected. No concerns. Please return responses to city comments by January 23, 2020, for inclusion in the Planning Commission packet on January 28, 2020. Sincerely, Zack Carlton Planning Manager 763.635.1035 February 27th, 2020 Zack Carlton City of Elk River 13065 Orono Parkway Elk River, MN 55330 Re: 2020 Elk River High School Parking Lot Improvements BKBM Prcj ect No. 17445.01 Dear Mr. Carlton: BKBM ENGINEERS The following letter is in response to the city review comments you provided for the Elk River High School Parking Lot Improvements project on January 15th, 2020. After reviewing the below responses, please let me know if you have any additional questions or require any additional information at this time. Response to City Comments: Note each number below corresponds to the numbered comment from the City's January 15th review letter. 1. The three drop off lanes at the main entrance to the High School is similar to what was recently installed at Prairie View Elementary and Middle School in the ISD #728 School District. The intent is for the lane closest to the building to be drop off and pick up, while the other two lanes are for thru traffic. To date, this layout has performed well at Prairie View and, to our knowledge, no safety issues have resulted from the three lane concept. 2. Drop off signage and arrows will be provided adjacent to the drive and on the pavement. A speed table (similar to a speed bump) is being provided at the main entrance to the High School, Ice Arena, and football stadium. There are also blinking pedestrian crosswalk signs being proposed on both sides of the drive at these locations. Within the parking lot itself, a combination of stop signs and speed tables are being proposed to slow down traffic. 3. Signage for the Ice Arena will be added to sheet C4.001 in accordance with the City and School District's agreement. Per conversation with city staff, it is BKBM's understanding these signs are to indicate "Ice Arena Parking Only 8am-4pm". 4. Per the City's agreement with the School District, 75 parking stalls are to be allocated to the Ice Arena (see previous response). It is our understanding these 75 stalls were intended to accommodate the typical user for the arena and staff. Deliveries, maintenance services, visiting buses, and emergency vehicle circulation should be discussed with the Ice Arena design team. Note that turning movements around the three -lane ring road was modeled for a 53-foot semi -truck. The semi -truck is also able to loop around the ice arena on the proposed fire loop that is to be installed as part of the ice arena project. 5. The following comments are in response to the safety concerns regarding the traffic signal relocation. a. Students will be able to cross School Street at the proposed traffic light location. In addition, a flashing crosswalk is being proposed as part of the City's planned 6120I_wre E:tr(min I'.",)rlv4. w°.ul'te 700, M1iunewlrr0,f NAN 55430 763-843-0420 3507 (::°sc�uri w°itiulte 105, C",)e ever, C,C) �,(tT'y16 /20.515.9$:(0 WWW al ll,)Inn tacnn improvements for school street. The flashing crosswalk is similar to the flashing crosswalks that are currently installed for Parker Elementary School and Lincoln Elementary School. i. The flashing crosswalk is being installed to provide a safe crossing location for students in this location. It should be noted that the spacing for the flashing crosswalk and the semaphore intersection is approximately the same as the spacing between the flashing crosswalks at Parker Elementary School and Lincoln Elementary School. ii. As stated in the previous city comment, human nature is to take the most direct path from point A to Point B. It is anticipated that students will use the Lions Park trail and recently installed sidewalk along Lions Park Drive to access the proposed flashing crosswalk. iii. The flashing crosswalk that is being installed should provide a safe crossing location for student athletes and coaches. In addition, it is anticipated that many students will likely drive to the practice field rather then walk from the school so they don't have to carry their equipment such a long distance. b. The flashing crosswalk is being proposed to provide a safe crossing for School Street. c. Based on the traffic study provided by Wenck Engineering, no impact to Proctor Avenue is anticipated. The current study shows the traffic light will "clear" after each cycle and the maximum queue length at peak traffic is expected to be approximately 160' (approximately half the distance to the existing VandenBerge drive entrance). d. See previous comment regarding the maximum anticipated queue length. Cars are not expected to backup to the existing drive entrances for the apartment complexes mentioned. 6. See attached fire truck turning movements for the site. If there are more specific concerns from the MN Fire Code Chapter 5, Appendix D, please elaborate. 7. Electrical charging stations are not currently planned for the high school parking lot. If conduit for future charging stations is needed, please provide a drawing showing where this conduit should be installed. 8. Understood. If you have any questions, please contact me.
