HomeMy WebLinkAbout5B - Timothy Avenue and CSAH 42 Intersection AGENDA #: PREPARED BY: SUBJECT: DATE: BACKGROUND: DISCUSSION: STAFF AGENDA REPORT ~~ BOYLES, CITY MANAGE~~ PRESENTATION - SANDEE WRIGHT AND BUSINESS OWNERS REGARDING TIMOTHY AVENUE AND CSAH 42 INTERSECTION. NOVEMBER 3, 1997 Councilmembers may be aware that a developer has proposed a commercial development on the Northwest quadrant of County Road 42 and State Highway 13 in Savage. The initial development contemplates a Rainbow Foods store. However, the ultimate development includes a second large anchor and additional retail facilities. The developer has indicated that for the development to work that both Connelly Lane and Timothy Avenue would be needed as full access intersections. The City of Savage and the City of Prior Lake met with the developer. The two cities agreed that it would be appropriate to have a traffic study performed to analyze the alternatives for placement of a traffic signal on County Road 42. Savage's motivation is to determine whether there is engineering criteria which would validate the appropriateness of a full access intersection with signals at Timothy and County Road 42. The County has historically taken the position that this intersection would be too close to the TH 13 / County Road 42 intersection. The City of Prior Lake, on the other hand, has been concerned about the impact such a development would have on residents of Timothy Avenue and conversely on the businesses along Commerce Avenue. I have previously shared a draft copy of the engineering study with Councilmembers. Sandee Wright, a resident of Timothy Avenue, has also received a draft copy as have the business owners along Commerce Avenue. A final copy of the traffic analysis is to be provided on Friday, November 1st, which is after the deadline for the agenda distribution. The preliminary study indicates that in the short run, a full access traffic intersection would function 16200 Eagle Creek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph.

The County is of the opinion that the distance between the Timothy Avenue intersection and the TH13 intersection would be too short for safety purposes and consequently, the Timothy Avenue intersection should remain as is. It should be noted that these positions have not been approved by the County Board but are only preliminary staff responses. While there is no specific proposal before the Savage City Council, Scott County, or the City of Prior Lake, Ms. Wright asked in an October 23, 1997 letter to Mayor Andren for the opportunity to address the City Council at its November 3rd meeting. I have therefore placed this item on the agenda as a presentation item. In fairness, I have contacted a number of business owners along Commerce Avenue since any revisions to the existing Timothy Avenue / CSAH 42 intersection would also affect them. One or more of them may be in attendance to express their views as well. Until the City receives a specific proposal either from the County or City of Savage to modify the Timothy Avenue intersection in one fashion or another, it does not appear appropriate to take any action aside from collecting input from the neighbors and property owners.

Parking SRF No. 0972802 DRAFT MEMORANDUM TO: David Hutton, P.E. City of Savage FROM: Dennis Eyler, P.E., Principal Erik Minge, P.E., Senior Engineer DATE: October 16, 1997 SUBJECT: TH 13/CSAH 42 AREA TRAFFIC STUDY INTRODUCTION As you requested, we have completed a traffic study for the proposed development in the northwest quadrant of TH 13 and CSAH 42 in Savage, Minnesota (see Figure 1: Project Location). This study includes an analysis of the existing and future traffic conditions within the study area. Traffic was generated and distributed to the surrounding roadways for both the proposed and future developments. Several alternatives were developed to provide access to the site. These alternatives were evaluated with respect to the signal coordination along the TH 13 and CSAH 42corridors. EXISTING CONDITIONS Both TH 13 and "CSAH 42 are 4-lane divided roadways within the study limits. The posted speed limit on each roadway is 40 mph. TH 13 is classified as a "A" Minor Arterial. The classification of CSAH 42 as a Principal Arterial is currently under review. The following full access intersections are located on CSAH 42 between Boone Avenue and TH 13: Boone Avenue, Harbor Place, Rutgers Street, and Timothy Avenue. Three private driveways between Rutgers Street and Timothy Avenue also have access to CSAH 42. Intersections on TH 13 are located at Connely Parkway, CSAH 42, and Commerce Avenue. The only intersection currently signalized is TH 13 and CSAH 42. The remaining intersections are minor approach stop-controlled. (see Figure 1: Project Location).

Fax (612) 475-2429 . http:/ /www.srfconsulting.com An Equal Opportunity Employer David Hutton, P .E. -2- October 16, 1997 Traffic operations were analyzed at the following intersections: . TH 13 and Connely Parkway . TH 13 and CSAH 42 . TH 13 and Commerce Avenue . CSAH 42 and Boone A venue . CSAH 42 and Harbor Place . CSAH 42 and Rutgers Street . CSAH 42 and Timothy Avenue Existing traffic operations in the p.m. peak hour were analyzed using current traffic counts (see Figure 2: Existing P.M. Peak Hour Traffic Volumes). Analysis found all of the intersections to operate at an acceptable Level of Service C or better, with the existing traffic controls and geometric layout. PROPOSED DEVELOPMENT The proposed development would be located in the northwest quadrant of TH 13 and CSAH 42. The development includes large retail and grocery stores, as well as several outlying businesses. There is potential for future development immediately west of the current proposed site (see Figure 3, Proposed Site Plan). The existing p.m. peak hour at the intersection of TH 13 and CSAH 42 is from 4:45 to 5:45 p.m. The p.m. peak hour was selected for analysis because the traffic generated by the proposed development will have the most impact on the surrounding roadway system during this hour. TRAFFIC FORECASTS Trip generation rates were estimated for the specific proposed land uses based on the rates obtained from the 1991 ITE Trip Generation Reports (see Table 1: Trip Generation Rates). Rates for the grocery/retail store anchor of the proposed development were calculated in two ways. First as a combined shopping center rate and then as separate rates for grocery and retail. The more conservative higher rate generated by the separate grocery and retail rates was selected. Appropriate trip generation rates were used for the remaining land uses. For future development, a shopping center rate was assumed for the seven outlying lots. The 14 acre site immediately west of the proposed site was assumed to be developed as a movie theater complex. Trips were generated based on this land use. David Hutton, P.E. - 3 - October 16, 1997 Trips were also generated for the proposed residential developments north of the study area. A rate of one trip per household was assumed during the p.m. peak hour.

The directional trip distribution for the proposed site-generated traffic was based on current distribution of traffic in the project area, during the p.m. peak period. A differing rate in the north and south directions was used to reflect the heavy southbound movement during the p.m. peak hour (see Figure 4: P.M. Peak Hour Directional Distribution). The site generated trips were reduced to reflect multiple use and bypass trips. David Hutton, P.E. -4- October 16, 1997 ACCESS ALTERNATIVES The following five alternatives were developed to accommodate both the short and long- term development plans for the site (see Figures 5 to 9). · Alternative 1: Addresses proposed development only. Analysis based on existing traffic levels plus traffic generated by the proposed development. Provides full access on CSAH 42 with a signalized intersection at Timothy A venue. Site access is also provided from Connely Parkway. Access to the residential areas south of CSAH 42 is provided at Harbor Place and Rutgers Street. Access is also retained to the north to the golf driving range. . Alternative 2: Addresses proposed development only. Analysis based on existing traffic levels plus traffic generated by the proposed development. Provides full access with a signalized intersection at Rutgers Street. Site access is also provided from Connely Parkway. Access to the residential areas south of CSAH 42 is provided at Harbor Place and Timothy A venue. The building at the golf driving range would have to be removed or relocated. . Alternative 3: Addresses full-build development. Analysis based on existing traffic levels plus traffic generated by future developments (full-build) and the proposed residential developments north of the site. Provides full access with a signalized intersection at Timothy A venue and partial access at Harbor Place. Access to the site is also provided from Connely Parkway. Access to the residential areas south of CSAH 42 is provided at Harbor Place and Rutgers Street. . Alternative 4: Addresses full-build development. Analysis based on existing traffic levels plus traffic generated by future developments (full-build) and the proposed residential developments north of the site. Provides full access with a signalized intersection at Timothy Avenue and partial access at Harbor Place. Access to the site is also provided from Connely Parkway. Access to the residential areas south of CSAH 42 is provided at Harbor Place and Rutgers Street. The only difference between alternative 3 and alternative 4 is the location of left turn access to the residential area south of CSAH 42. . Alternative 5: Addresses full-build development. Analysis based on existing traffic levels plus traffic generated by future developments (full-build) and the proposed residential developments north of the site. Provides full access with a signalized intersection at Rutgers Street and partial access at Timothy A venue. Access to the site is also provided from Connely Parkway. Access to the residential areas south of CSAH 42 is provided at Harbor Place and Timothy Avenue. David Hutton, P.E. - 5 - October 16, 1997 Hill access movements into and out of residential areas south of CSAH 42 will likely be restricted as described for each alternative. In some cases a northbound to westbound movement must be made by first heading east and then taking a V-turn at the first signalized intersection. Traffic accessing Harbor Place will be especially impacted because CSAH 42 provides the only access to this area. The geometrics at relevant intersections must be reviewed if U-turns are to be provided. The locations of U-turn maneuvers are indicated in figures 5 to 9. Note that these alternatives address both interim and ultimate conditions. Alternative 1 could be selected to accommodate the proposed development and, as further development occurs, alternatives 3 or 4 could be implemented to handle the increased traffic. Similarly, alternative 2 could be upgraded to alternative 5. IMPACT TO PRIOR LAKE The proposed alternatives will impact the residential and commercial areas of Prior Lake in the southwest quadrant of TH 13 and CSAH 42. The impacts to the residential neighborhoods of Prior Lake are found primarily in alternatives 1, 3, and 4 which provide full access at Timothy Avenue. Some of the traffic generated by the proposed development and from CSAH 42 west of Timothy A venue will use Timothy A venue to bypass the TH 13/CSAH 42 intersection. These motorists would travel south to Boudin Street and east to TH 13. Since only right-in-right-out movements will be allowed at Boudin Street and TH 13, the reverse movement is not possible. In addition, alternatives which provide partial access at Timothy Street will also experience some of the same cut- through traffic. The following options will mitigate the cut-through traffic on Timothy Avenue: .....-A,.. [1. Close Timothv Avenue at Commerce Avenue.) ;rq 2. Make the intersection of Timothy A venue and Commerce A venue a one-way out in the northbound direction. 3. If Timothy Avenue is full-access, prohibit north/south through movements at CSAH 42. 4. Install traffic calming measures such as speed humps or intersection throating along The first two options listed above would be the most effective at eliminating cut-through traffic while still maintaining access at Timothy Avenue. Note that cut-through traffic is not likely to use Rutgers Street because the trip to TH 13 would be circuitous (see Figure 1: Project Location). David Hutton, P.E. -6- October 16, 1997 The proposed alternatives will also affect access to the commercial area in the southwest quadrant of TH 13/eSAH 42. Currently Timothy Avenue is full access, allowing movements to and from both directions of CSAH 42. Alternatives 1, 3, and 4 maintain this full connection. Alternatives 2 and 5, however, allow right-in-right-out and left-in movements, but prohibit the left-out movement. This northbound to westbound movement could be made by turning east onto CSAH 42 and then taking a u-turn at TH 13 to head west. Another option for improving access is to construct a frontage road between Rutgers Street and Timothy A venue south of CSAH 42. FUTURE TRAFFIC OPERATIONS ANALYSIS In order to determine how well existing and proposed roadways will accommodate the proposed developments, a traffic operational analysis was conducted for each of the proposed alternatives. Using existing traffic volumes, trips generated, and the directional trip distribution, future p.m. peak hour traffic volumes were calculated for each alternative (see figures 10 to l4). The volumes and geometrics were modeled with the SYNeHRO 3 traffic analysis software. All of the intersections to be signalized in each alternative were modeled to operate in a coordinated system with signal interconnect. The software selected 120 seconds as the optimal cycle length for all of the intersections, but after discussion with MnlDOT traffic personnel, a cycle length of 150 seconds was selected as more realistic for the corridors. The signals were allowed to operate with leading or lagging left-turn phasing. Signal timings were adjusted at Boone A venue and CSAH 42 to account for the low-volume of traffic on Boone A venue. To provide more realistic timing, the minimum pedestrian crossing time was used. The traffic analysis provided volume to capacity ratio (V/e) , Level of Service (LOS), intersection delay, and queue lengths for each of the intersections for each of the alternatives (see Table 2: Operational Analysis by Alternative). In addition, a signal warrant analysis was conducted for each of the proposed signalized intersections. Warrants 1, 2 and 8 examine traffic in the eighth highest hour. Warrant 11 examines p.m. peak period traffic (see Table 3: Warrant Analysis).

Long-range traffic forecasts for the region indicate substantial growth in the area. The Average Daily Traffic (ADT) on CSAH 42 between Boone A venue and TH 13 is expected to increase from approximately 17,000 to 25,000 by the year 2020, an increase of about 45 percent. The ADT on TH 13 north of CSAH 42 is expected to grow from 16,OOO to 21,000 by the year 2020, an increase of about 30 percent. Additional analysis would be necessary to assess the future impact of traffic growth in the area. David Hutton, P.E. EVALUATION OF ALTERNATIVES - 8 - October 16, 1997 Several factors must be considered when evaluating each of the alternatives included in this analysis. In addition to effective traffic operations, safety issues are also important. A primary concern with closely spaced intersections is a heavy queue at one intersection that extends into and conflicts with the operation of an upstream intersection. Queues generated by left turning vehicles are often critical. Alternatives l, 3 and 4 involve a signalized intersection at Timothy Avenue, located 660 feet west of TH 13. In order to avoid conflicting queues between these closely spaced intersections they must operate in a coordinated fashion. In addition, left-turn lanes for westbound traffic at Timothy Street and eastbound traffic at TH 13 must be side-by-side in order to allow enough storage room to accommodate the anticipated demand (see Table 4: Spacing Considerations). TABLE 4 SPACING CONSIDERATIONS TH 13/CSAH 42 AREA TRAFFIC STUDY VARIABLE 1/4 MILE SPACING Accident rates Queuing problem potential Weaving problem potential Reaction time Spacing of successive decision points Side-by-side left turn lanes required I Importance of signal coordination Signal operation Consistenc with s acin uidelines 1/8 MILE SPACING average possible possible minimally acceptable minimally acceptable yes hilYh ---0-- good no average low low better better no medium good es Analysis of queuing and weaving conditions indicate that the 1/8 mile spacing between Timothy Avenue and TH 13 can operate safely. Adequate storage length can be provided to accommodate most of the projected queue lengths. The only exception is a heavy queue expected on eastboundCSAH 42 at TH 13 which may conflict with traffic at Timothy Avenue (see Table 2: Operational Analysis by Alternative). Traffic signal timing can be adjusted to mitigate this impact. David Hutton, P.E. -9- October 16, 1997 The weaving conflict on westbound CSAH 42 is caused by vehicles making a left at Timothy Avenue. The existing volume for this movement is 80 vehicles in the p.m. peak hour. Approximately 35 percent or 28 of these vehicles are estimated to originate from southbound TH 13 and weave to the left turn lane. This volume can make such a maneuver safely. The weaving conflict for eastbound CSAH 42 is caused by vehicles exiting left from the development and making a right at TH 13. The exiting volume is as high as 437. Approximately 35 percent or 150 vehicles are expected to make a right turn at TH 13. This volume is relatively high but can be handled effectively if the right turn bay on TH 13 is made long enough to accept this movement. In order to improve northern access to the proposed development, full access is recommended from Connely Parkway between 400 and 600 feet west of TH 13. This location would move the direct access closer to TH l3 while still providing adequate storage for left-turning vehicles along Connely Parkway. The correlation between accident rate and intersection spacing is not easily quantified. Several variables including sight distance, weaving maneuvers and approach speeds affect the accident rate. A similar spacing exists on TH 55 in Golden Valley where the speed limit is 55 mph. TH 55 has intersections of Winnetka A venue and Rhode Island Avenue spaced 1/8 of a mile apart. The next signalized intersection is Boone Avenue, located 1/2 mile to the west. The 1992 MnJDOT accident study found Winnetka A venue and Boone A venue to have the same accident rate. The selection of access points along a corridor is subject to considerations such as the roadway's functional classification, physical limitations, spacing guidelines, existing and proposed land uses, and the ability to provide frontage or backage roads to mitigate access limitation impacts. The spacing of access along a roadway impacts the minimum speed and mobility that may be attained. The functional classification of CSAH 42 is under revie\v and may be do\vngraded from a Principal i\rterial to a "l\." ~Ainor Collector. If this change is made the access spacing becomes more lenient. Quarter mile spacing is recommended for full access intersections on County Highways. Rutgers Street is located 1/4 mile between Boone Avenue and TH 13. Timothy Street is located 1/8 mile west of TH 13. CONCLUSION This study has determined that from a safety and traffic operations viewpoint, a signalized full-access intersection at either Rutgers Street or Timothy A venue will operate successfully if implemented as described. Beyond safety and operations, consideration must be given to the access guidelines developed for roadways such as CSAH 42. A spacing of less than 1/4 mile violates intersection spacing guidelines. Whichever alternative is selected, the impacts to residential and commercial areas of Prior Lake must be considered. EDM:bba l!S Tlt'5N if:l. .~~.

The best location for this signal is at Rutgers Street In conjunction with a signal at Rutgers Street, a partial access inter:~cclion could be allowed at Timothy Avenue a~ $hown with Alternative 5. This prvposcd combination of traftic signal at Rutgers Street and parti.\1 access at Timothy Avenue will adequately serve the projected traffic volumes through the year 2020. However, the existing and site generated traffic could be he:lOdled in the year of opening with signalized access at Timothy Avenue and partial access at Rutgers Street as described in Alternatives 3 or 4. The traffic queues generated by this conJigurarion will build over time and eventually exceed the 660 foot spacing between the intersections, presenting a safety problem, Thus Timothy Avenue could be conS[[1Jcted as a temporary signal and then moved to Rutgers Street as shown in Alternative 5 when traffic levels increase. This scenario is complicated by the fact that moving the signal wili requin: a written agreement with specific guidelines for determining when the change will occur. Intersection spacing guidelines recommend 1/2 mile spacing for full. acce.~~, intersections along a Principal Arterial. This guideline implies Boone Avenue and TH 13 would bl: the only signalized intersections allowed in the study area. The Principal Arterial classification for CSAH 42, however, is under review. In addition to trajfic op(;ra.tirms isslIes, consideration must also be given to the impact each alternative has on [he residential and commercial area$ in the City of Prior Lake south of CSAH 42. At (his time the City of Prior Lake has not provided clear indication of which alternarive they prefer. tV Timothy Avenue Residents Presentation to City Council November 3. 199i Summary of Requests for Action: 1. Oppose the installation of a signal Iight- either permanent or temporary at Timothy Avenue. 2. Support the installation of a signal light at Rutgers Street. 3. Re-evaluate the plan for access to State Road 13. to- ~ I> ~ ~t.t1\.~' 4. Close Timothy Avenue to through traffic. ,.i? .
