III.3. CR2024-109 - 11th Avenue Corridor Study CITY OF HOPKINS City Council Report 2024-0109 To: Honorable Mayor and Council Members Mike Mornson, City Manager From: Eric Klingbeil, PE, City Engineer Date: September 10, 2024 Subject: 11th Avenue Corridor Study _____________________________________________________________________ OVERVIEW 11th Avenue is a significant corridor in Hopkins, acting as the main north-south corridor connecting residential, industrial, and commercial areas to Excelsior Boulevard, downtown, and points beyond. While 11th Avenue south of Mainstreet is not scheduled for a reconstruction or other significant rehabilitation project along the length of the corridor in the near future, there are several smaller scale projects planned in the short and long term. This report was created in order to help identify opportunities along the corridor while providing for a cohesive vision for projects in the corridor allowing incremental projects to be part of a larger, holistic improvement. SUPPORTING INFORMATION o 11th Avenue Corridor Planning Study, Draft o Minnesota River Bluffs Regional Trail Concept Layout ANALYSIS OF ISSUES BACKGROUND INFORMATION Pedestrian access and safety, and vehicle speeds are some of the most common resident comments about 11th Avenue. This is a vital corridor for a diverse set of users, including a large non-car dependent population, recreational trail users, and vehicle traffic. The Capital Improvement Plan includes upgraded pedestrian crossings on 11th Avenue South, with additional longer range improvements for the future. Recently Three Rivers Park District engaged Hopkins staff about planned improvements to the Nine Mile Regional Trail that may have direct impacts to 11th Avenue. Staff felt a study of the corridor was warranted to ensure that improvements by all parties were warranted, did not interfere will traffic flow, and fit together with a single vision for the corridor. The City contacted a local engineering firm, SRF, to perform a corridor study of 11th Avenue from Mainstreet to Smetana Road. This study analyzed existing parking, pedestrian facilities, traffic speed and volume, turning movements, intersection Public Works Dept. capacity, and roadway layouts. Recommendations on pedestrian facilities, and roadway and intersection geometry are made in the report. Currently, the draft report has been submitted to departments city-wide for review, including police, fire, planning, and public works. Staff is planning to work with the consultant to finalize the report with any staff or council input incorporated.

The main objectives of the study are to review existing traffic and parking conditions along the corridor, determine potential corridor wide and intersection specific modifications to improve safety and mobility for all users, and develop concept layouts and cost estimates for intersection alternatives identified along 11th Avenue South. The following information provides the assumptions, analysis, and study findings offered for consideration. Existing Conditions Existing conditions were reviewed to establish a baseline to identify any potential issues and opportunities, as well as determine improvement alternatives. The evaluation of existing conditions includes a review of traffic volumes and speeds, roadway characteristics, and an intersection capacity analysis, which are summarized in the following sections. Data Collection Weekday a.m. and p.m. peak period vehicular turning movement and pedestrian/bicyclist counts were collected by SRF during the week of March 11, 2024, at the following study intersections along 11th Avenue South: ▪ Mainstreet ▪ 1st Street S ▪ 5th Street S ▪ 6th Street S ▪ 7th Street S ▪ Westbrooke Way ▪ Smetana Road In addition to the collected counts, previously collected counts from April 2023 at the intersection of 11th Avenue South and Excelsior Boulevard were used for the analysis.

A summary of these roadway characteristics is shown in Table 1. Table 1. Existing Roadway Characteristics (1) Functional classification based on the City of Hopkins’ 2040 Comprehensive Plan. (2) Note that 11th Avenue S changes to a 2-lane undivided roadway south of the marked pedestrian crossing that is just to the north of Landmark Trail N. (3) Smetana Road is a Major Collector east of 11th Avenue S and a local road west of 11th Avenue S. From a traffic control perspective, the 11th Avenue South intersections of Mainstreet, Excelsior Boulevard, and 5th Street South are signalized. The intersection of 11th Avenue South and Westbrooke Way is unsignalized with side-street stop control, while the other study intersections are unsignalized with all-way stop control. Existing geometrics, traffic controls, and traffic volumes in the study area are shown in Figure 2. Parking Counts Parking counts were conducted in April 2024 during the midday peak on a Friday and overnight on a Sunday. The collected parking counts are shown in Figure 3. Note that the parking counts show the maximum number of parked vehicles during all three periods of data collection. Based on the parking surveys, on-street parking along 11th Avenue South is not significantly utilized.

In the near future, a METRO Green Line station will be opened approximately one-quarter mile east of 11th Avenue South, just south of Excelsior Boulevard and the Minnesota River Bluffs LRT Regional Trail. The Green Line will provide service from Eden Prairie to St. Paul. A multi-use trail is located along the east side of 11th Avenue South from Excelsior Boulevard to Smetana Road. There are also multi-use trail connections to both Nine Mile Creek Regional Trail and the Minnesota River Bluffs LRT Regional Trail. Sidewalk is located along the west side of 11th Avenue South from Mainstreet to 6th Street South and 7th Street South to Wagon Wheel Road; and along the east side of 11th Avenue South from Mainstreet to Excelsior Boulevard. A detailed review of the existing multi-use trails and sidewalks, driveway access locations, pedestrian crossing locations, curb bump out locations, missing trail/sidewalk connections, and roadway widths along the 11th Avenue South are shown in Figures 4 to 6. Speed and Daily Volume Data Speed and daily volume data was collected during the week of April 1, 2024, for a 24-hour period at three (3) locations along 11th Avenue South. Currently, 11th Avenue South within the study area is a 30 mile per hour (mph) roadway. Table 2 outlines the existing speed and volume data at the three study locations. Table 2. Existing Speed and Volume Data Based on the results, the average speed at both locations south of Excelsior Boulevard exceed the posted speed limit. The average speed at the location north of Excelsior Boulevard does not exceed the speed limit, however, the 85th percentile does exceed the speed limit at this location. 11th Avenue Data Collection Location Average Speed 85th Percentile Speed Average Daily Traffic North of 1st Street S 26.6 MPH 31 MPH 4,730 North of 5th Street S 33.2 MPH 38 MPH 8,575 North of Trailwood Lane N 32.2 MPH 37 MPH 4,660 02417591 April 2024 Existing Conditions - Mainstreet to 5th Street S 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 4 44’ 80’NORTHNorth52’ 65’ Average Speed - 32.2 MPH 85th Percentile Speed - 37 MPH Average Speed - 33.2 MPH 85th Percentile Speed - 38 MPH Average Speed - 32.2 MPH 85th Percentile Speed - 37 MPH Average Speed - 26.6 MPH 85th Percentile Speed - 31 MPH Excelsior Blvd 1st St S Mainstreet 11th Ave S11th Ave S - Multi-Use Trail - Sidewalk - Missing Trail/Sidewalk Connection - Driveway Access - Pedestrian Crossing Location - Curb Bumpout Location - Roadway Width LEGEND XX’ NORTHNorth02417591 April 2024 Existing Conditions - 5th Street S to Landmark Trail N 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 5 44’ 34’ 44’ - Multi-Use Trail - Sidewalk - Missing Trail/Sidewalk Connection - Driveway Access - Pedestrian Crossing Location - Curb Bumpout Location - Roadway Width LEGEND XX’ 27’ 5th St S 7th St S 6th St S Overhead Pedestrian Crossing Beacon Overhead Pedestrian Crossing Beacon NORTHNorth02417591 April 2024 Existing Conditions - Landmark Trail S to Smetana Road 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 6 40’ 44’ Average Speed - 32.2 MPH 85th Percentile Speed - 37 MPH Westbrooke Way 11th Ave SSmetana Rd - Multi-Use Trail - Sidewalk - Missing Trail/Sidewalk Connection - Driveway Access - Pedestrian Crossing Location - Curb Bumpout Location - Roadway Width LEGEND XX’ Overhead Pedestrian Crossing Beacon Overhead Pedestrian Crossing Beacon 11th Avenue Corridor Planning Study August 2, 2024 Page 10 Intersection Capacity Analysis An intersection capacity analysis was completed using Synchro/SimTraffic software (version 11) to establish a baseline condition to which potential alternatives could be compared. Capacity analysis results identify a Level of Service (LOS) which indicates how well an intersection is operating. Intersections are graded from LOS A through LOS F. The LOS results are based on average delay per vehicle, which correspond to the delay threshold values shown in Table 3. LOS A indicates the best traffic operation, while LOS F indicates an intersection where demand exceeds capacity. Overall intersection LOS A though LOS D is generally considered acceptable by drivers in the Twin Cities Metropolitan Area. Table 3. Level of Service Criteria for Signalized Intersections LOS Designation Signalized Intersection Average Delay/Vehicle (seconds) Unsignalized Intersection Average Delay/Vehicle (seconds) A ≤ 10 ≤ 10 B > 10 – 20 > 10 – 15 C > 20 – 35 > 15 – 25 D > 35 – 55 > 25 – 35 E > 55 – 80 > 35 – 50 F > 80 > 50 For side-street stop/yield-controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an unsignalized intersection with side-street stop/yield control can be described in two ways. First, consideration is given to the overall intersection level of service. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support these volumes. Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, the majority of delay is attributed to the side-street approaches. It is typical of intersections with higher mainline traffic volumes to experience high-levels of delay (i.e. poor levels of service) on the side-street approaches, but an acceptable overall intersection level of service during peak hour conditions. Results of the existing capacity analysis, shown in Table 4, indicate that all study intersections currently operate at an acceptable overall LOS B or better during the a.m. peak hour, and an acceptable overall LOS C or better during the p.m. peak hour, with the existing geometric layout and traffic controls. 95th percentile queues for the northbound shared left/through lane at 1st Street South are approximately 75 feet during the a.m. peak hour and 70 feet during the p.m. peak hour. During the p.m. peak hour, 95th percentile queues for the southbound approaches at 6th Street South and 7th Street South are approximately 105 feet and 90 feet, respectively. The westbound approach at Smetana Road has 95th percentile queues of approximately 75 feet during the p.m. peak hour. There are no existing significant queueing issues within the study area. 11th Avenue Corridor Planning Study August 2, 2024 Page 11 Table 4.

Alternative Options Based on the existing volumes, operations, and pedestrian facilities within the study area, there are options for potential modifications throughout the study area. This includes modifying the roadway section within the right-of-way to reallocate more space for pedestrians and bicyclists, along with filling any gaps. Additionally, crossing improvements were identified for consideration throughout the corridor. There are four (4) distinct areas of the corridor with slightly different needs. These include: • Smetana Road to Landmark Trail • Landmark Trail to 5th Street S • 5th Street S to 1st Street S • 1st Street S to Main Street Portions of the segment of 11th Avenue between 5th Street S and 1st Street S have recently been reconstructed as part of the ongoing Green Line Extension project, which included an enhanced pedestrian crossing just north of the LRT tracks. Additionally, the lanes within the area are generally needed to accommodate the traffic volumes and queues at the Excelsior Boulevard intersection. Therefore, no modifications are proposed for this area. Smetana Road to Landmark Trail This segment of 11th Avenue is currently a two (2) lane roadway that is approximately 44 feet wide and no painted shoulders. There is an enhanced pedestrian crossing at Westbrooke Way with an overhead flashing beacon and curb extensions (east side of roadway only). Average and 85th percentile travel speeds along the corridor exceed the posted speed limit. 11th Avenue Corridor Planning Study August 2, 2024 Page 12 There was minimal parking observed along the corridor, with six (6) vehicles parked on the west side and three (3) vehicles on the east side at their highest peak demand periods. Based on this information, the following options could be considered: • 2 Lane (South of Westbrooke Way) – Option 1 o 12 foot lanes o add 6 foot sidewalk on west side south of Westbrooke Way with 2 foot boulevard o 4 foot shoulder (west side, south of Westbrooke Way) o 8 foot shoulder (east side) • 2 Lane (South of Westbrooke Way) – Option 2 o 12 foot lanes o add 6 foot sidewalk on west side south of Westbrooke Way with 2 foot boulevard o 3 foot shoulder (west side, south of Westbrooke Way) o 3 foot shoulder (east side) o 6 foot boulevard (east side) • 2 Lane (North of Westbrooke Way) – Option 1 o 12 foot lanes o 10 foot shoulders • 2 Lane (North of Westbrooke Way) – Option 2 o 12 foot lanes o 4 foot shoulders o 6 foot boulevards • 3 Lane (37 to 41 feet wide) o 12 foot lanes o 4 foot shoulders, no parking It is recommended to enhance the pedestrian crossing at Westbrooke Way with curb extensions on both sides of the roadway and push button activated rectangular rapid flashing beacons (RRFB). Additionally, a new pedestrian crossing located at the trail connection between the Raspberry Woods townhomes and 11th Avenue is recommended to include curb extensions. A RRFB could be considered at this location, if desired. Note, there is not a sidewalk or trail along the west side of 11th Avenue between approximately Westbrooke Way and Smetana Road. It is recommended to install a sidewalk connection between Westbrooke Way and the trail to the Raspberry Woods townhomes along the west side of the roadway. Additional sidewalk or trail to Smetana Road could be considered in the future if additional trail/sidewalk connections are constructed. Given the wetland conditions within the area, it may not be feasible for those connections to be made. 11th Avenue Corridor Planning Study August 2, 2024 Page 13 Based on the sidewalk/trail needs on the west side of the roadway, it is recommended that either 2 lane roadway configurations be considered for 11th Avenue between Smetana Road and Landmark Trail. The reduced roadway space will allow for the sidewalk/trail connection on the west side of the roadway without requiring additional right-of-way and for safer pedestrian crossings. The current roadway configuration allows for high travel speeds and accommodates significantly more on-street parking than is necessary. It is not expected that a 3 lane roadway configuration will be necessary from an operations perspective, as sufficient gaps are available for left-turning vehicles. Given the recommended 2 lane configuration, it is not expected that traffic would operate any differently from a delay or queueing perspective. A layout the two configurations is shown in Figures 7 and 8. Additionally, a Streetmix layout is included as an attachment. Landmark Trail to 5th Street S This segment of 11th Avenue is currently a two (2) lane roadway near Landmark Trail and the pedestrian crossing then expands to a 4 lane section near the shopping center to 5th Street S. The roadway is approximately 44 feet wide and currently travel speeds can exceed the speed limit. There is an enhanced pedestrian crossing north of Landmark Trail at the shopping center with an overhead flashing beacon and curb extensions (east side of roadway only). There was no on-street parking allowed within this segment of the roadway. This segment of 11th Avenue passes underneath the railroad bridge immediately south of 5th Street S. Note, the intersections at 7th Street S and 6th Street S are all-way stop controlled and the intersection at 5th Street S is signalized. There is sidewalk on both sides of the roadway between Landmark Trail and 7th Street S and 6th Street S to 5th Street S. Between 7th Street S and 6th Street S, there is trail (Nine Mile Creek Regional Trail) only on the east side of the roadway. Three Rivers Park District is currently reviewing options to replace the sidewalk on the east side of 11th Avenue between 7th Street S and 5th Street S to a 10 foot wide trail segment with boulevards. This trail expansion/connection would require modifying the roadway cross section and reducing travel lanes. Based on this desire, it is unlikely the current 4 lane roadway layout could remain. Therefore, based on this information, the following general roadway geometric options could be considered: • 2 Lane – 12 foot lanes, 4 foot shoulders – No Parking • 2 Lane with Parking one side – 12 foot lanes, 8 foot parking lane (one side), 4 foot shoulder (one side) • 3 Lane –12 foot lanes– No Parking, center left-turn lane, 4 foot shoulders NORTHNorth02417591 April 2024 Potential Future Configuration - Landmark Trail S to Smetana Road - Option 1 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 7 Westbrooke Way Smetana Road Add curb extensions and consider installation of RRFB at new trail crossing Add curb extension on west side and replace overhead beacon with RRFB Tighten 11th Avenue either with moving curbs in or striping shoulders and fill sidewalk gap on west side NORTHNorth02417591 April 2024 Potential Future Configuration - Landmark Trail S to Smetana Road - Option 2 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 8 Westbrooke Way Smetana Road Add curb extensions and consider installation of RRFB at new trail crossing Add curb extension on west side and replace overhead beacon with RRFB Tighten 11th Avenue either with moving curbs in or striping shoulders and fill sidewalk gap on west side 11th Avenue Corridor Planning Study August 2, 2024 Page 16 It is anticipated that the enhanced pedestrian crossing just north of Landmark Trail would remain in that location, however, a formal curb extension on both sides of the roadway is recommended to be constructed, along with replacing the overhead flashing beacon with a push button activated RRFB.. If feasible, it is recommended to fill in the sidewalk gap along 11th Avenue between 6th Street S and 7th Street S. This would allow a pedestrian crossing on the south side of the 6th Street S intersection, which would have fewer left-turning vehicles conflicts and is located on the approach where pedestrians are ultimate destined given the residential land uses to the southeast of the intersection. If a 3 lane configuration was desired, there is potential that the pedestrian crossing on the south approach of the 6th Street S intersection could include a median refuge given the low northbound left-turning volumes. In addition to the lane modifications, there could be consideration of modifying the traffic control at the 7th Street S, 6th Street S, and 5th Street S intersections. The 7th Street S and 6th Street S intersections could potentially be modified to a side-street stop control, while the 5th Street S intersection could be modified to either an all-way stop or side-street stop control. A review of the potential operational changes is shown in Table 5 for the various lane and traffic control scenarios. Table 5.

However, additional considerations are given at the study intersections. At the 5th Street S intersection, there may be sight distance issues for eastbound vehicles due to the railroad bridge. Additionally, there may be considerations for heavy vehicles at this intersection given their need for larger gaps in traffic. A detailed Intersection Control Evaluation (ICE) report may be needed to formally determine the appropriate traffic control at the intersection. At the 6th Street S intersection, it is expected that the current all-way stop control is not needed for efficient traffic operations. This intersection may be able to be reduced to a side-street stop control. At the 7th Street S intersection, a modification to a side-street stop control could be considered, however, given the pedestrian crossings and land uses surrounding the intersection, the all-way stop control may be best suited for the intersection for safe pedestrian crossings and safe and efficient heavy vehicle maneuvers. From a geometric perspective, the segment of 11th Avenue between Landmark Trail and 5th Street is likely best suited for a 3 lane roadway with numerous public roadway and business accesses, including a shopping center and gas station. This includes one lane in each direction and a center left-turn lane. This layout would also best accommodate the proposed trail connection for the Nine Mile Creek Trail with Three Rivers Park District. There is not currently an observed need for parking along this stretch of the corridor, given the land uses have ample parking available. Therefore, there could be a lane reduction, which will allow for expansion of the trail segments, the filling of sidewalk ga ps, safer pedestrian crossing due to reduced crossing distances and removing multi-threats, and traffic calming. A layout of this segment of 11th Avenue is shown in Figure 9. Additionally, a Streetmix layout is attached. 1st Street S to Mainstreet This segment of 11th Avenue is currently a 4 lane section with two (2) northbound lanes (one northbound lane traps into a northbound right-turn lane at Mainstreet) and one (1) southbound lane and a southbound parking lane. The roadway is approximately 42 to 44 feet wide. The intersection at 1st Street S is all-way stop controlled and the intersection at Mainstreet is signalized. There is sidewalk on both sides of the roadway, however, on the east side of the roadway, there are light posts within the sidewalk area, which also carries a heavy pedestrian volume. During the peak demand time, there were four (4) cars parked on the west side of the roadway. Note, a residential development is currently being constructed on the west side of the roadway and it is expected that the primary garage access will be along 11th Avenue between 1st Street S and Mainstreet. Additionally, a large public parking facility is located on the east side of the roadway with an entrance along 11th Avenue. Therefore, based on this information, the following general roadway geometric options could be considered: • 2 Lane –12 foot lanes, 4 foot shoulders – No Parking, add sidewalk on east side • 2 Lane with Parking one side – 12 foot lanes, 8 foot parking lane, 2 to 4 foot shoulder, add sidewalk on east side • 3 Lane –12 foot lanes– No Parking, center left-turn lane, add sidewalk on east side NORTHNorth02417591 April 2024 Future Potential Configuration - 5th Street S to Landmark Trail N 11th Avenue Corridor Planning Study City of Hopkins, MN Figure 9 5th Street S 6th Street S 7th Street S Change to Side-Street Stop ControlConsider a median refuge crossing and fill sidewalk gap on west side of 11th Ave. Coordinate with TRPD on their trail expansion plans Keep as all-way stop control and add pedestrian ramps as needed Add curb extension on west side and replace overhead beacon with RRFB Modify 11th Avenue to a 3 lane section Possible control change Modify to dedicated left and thru lanes 11th Avenue Corridor Planning Study August 2, 2024 Page 19 In addition to the lane modifications, there could be consideration of modifying the traffic control at the 1st Street S intersection to a side-street stop control. An intersection capacity analysis was completed to compare the operations between these traffic control and geometric alternatives and is shown in Table 6. It is expected that all of the geometric or traffic control modification scenarios will allow for acceptable operations, however, the all-way stop control at the 1st Street S intersection may continue to be considered to allow for safe pedestrian movements, given the proximity to downtown Hopkins and City Hall.

The center left-turn lane will remove turning conflicts. Based on the existing parking counts, there is minimal parking demand along this segment of roadway, and that parking demand can be accommodated either north of the intersection along Mainstreet or 11th Avenue or within the public parking facility on the east side of the roadway. The reduction in lanes will allow for expanded sidewalk areas or boulevards to be installed to improve the pedestrian facilities. The recommended roadway layout is shown in Figure 10. Additionally, a Streetmix layout is attached.
