CR 96-169 Feasibility Report - 11th Ave SOctober 11, 1996 Proposed Action. Staff recommends adoption of the following motion: Move that Council adopt Resolution 96 -85, Resolution Ordering preparation of a Feasibility Report - 11 Avenue South and authorize the City Manager to enter into an agreement with SEH, Inc. for preparation of feasibility report and preliminary survey. This action is the first step in the process of improving 11 Avenue from the HCRRA trail to 5 Street South. The City has not received a petition to improve this segment of 11 Avenue. This road segment is a designated Municipal State Aid road. Overview. 11 Avenue South from County Road 3 to 5 Avenue South is the City's busiest street handling 13,000 vehicles on average per day. Further, additional development along the corridor has increased the total volume and the number of trucks. The existing road configuration with 11 foot wide lanes and no reaction zone at the curb is inadequate for the volume of vehicles and trucks. MSA Consulting Engineers reviewed the previous traffic studies and current conditions and has recommended that the street be widened from the current 44 feet to 52 feet. This would allow 4 - 12 foot • lanes with the required 2 foot reaction zone at the curbs. This width would also allow the City to convert to a 3 -lane roadway with a common center turning lane if desired. A feasibility study is the required first step in this proposed assessable street improvement project.

SINGLE SOURCE. SHORT ELLIOTT HENDRICKSON INC. • .=SEFI October 10, 1996 Steven 1. Stadler Director of Public Works City of Hopkins 11100 Excelsior Boulevard Hopkins, Minnesota 55343 Dear Steve: 5909 BAKER ROAD, SUITE 590, MINNETONKA, MN 55345 612 912 -2600 FAX 612 931 -1188 ARCHITECTURE • ENGINEERING • ENVIRONMENTAL • TRANSPORTATION SEH is pleased to be invited to submit this proposal for professional services necessary to complete the reconstruction of 1lth Avenue South from the Hennepin County Regional Rail Authority Trail southerly to 5th Street South. Review of this proposal will demonstrate that your needs on this project are best met by an engineering firm with the depth and diversity of experience of SEH. We have designed more than 100 miles of Municipal State Aid streets and more than 200 traffic signal systems, more than anyone in Minnesota other than Mn/DOT. We understand that the issues creating the need for this project largely relate to the capacity of 1 lth Avenue to carry vehicles and pedestrians. The 44 -foot width of 1 lth Avenue would typically accommodate two lanes of through traffic and parking on both sides. Due to the increasing level of traffic on this street, the City recently restriped the street for four 11 -foot lanes, with no reaction distance to the curb. This temporary situation needs to be replaced with a permanent improvement addressing all the needs. Some of the other issues related to the proposed improvements include: 1. Safe and efficient access for the two abutting properties 2. Pedestrian and recreational trail traffic 3. A transition to an acceptable lane configuration west of 11th Avenue on 5th Street and south of 5th Street on l lth Avenue 4. Meet the requirements of the Municipal State Aid design standards You have indicated the need to closely coordinate the scheduling of this project with the 1997 reconstruction project Hennepin County has planned for County Road 3 and 1 lth Avenue southerly to the Hennepin County Regional Rail Authority trail. The pavement structure for 11th Avenue currently in place is adequate. Accordingly, the proposed design process should attempt to save as much of the existing pavement as possible so that an overlay can tie the existing pavement into the widened street section. Sanitary sewer, water main, and storm sewer systems currently in place will only require minor adjustments to fit the new elevations of the proposed project. You also feel that the analysis and design of replacement systems will not be necessary. We understand the general scope of this project includes the following. 1. Widen 1 lth Avenue to 52 feet to better accommodate four lanes of traffic. 2. Construct traffic signals at the intersection of 1 lth Avenue and 5th Street. 3. Review driveway locations and relocate to reduce turning movement conflicts and provide the future opportunity to signalize one of the entrances into the two major properties if later deemed necessary. SHORT ELLIOTT HENDRICKSON INC. ST PAUL, MN ST CLOUD, MN CHIPPEWA FALLS, WI MADISON, WI LAKE COUNTY, IN EQUAL OPPORTUNITY EMPLOYER 4. Reconfigure the intersection of 1 lth Avenue and 5th Street. Traffic approaching the intersection from 5th Street will need to be accommodated by a left turn lane and a right turn lane, thereby requiring a striping plan westerly of 1 lth Avenue on 5th Street. 1 lth Avenue south of 5th Street will need to be restriped to accommodate two northbound lanes and one southbound lane. 5. A 5 -foot concrete walk abutting the westerly curb of 1 1th Avenue and an 8 -foot bituminous trail separated from the east curb of 1 lth Avenue need to be accommodated. 6. Signing, striping, retaining walls, and landscaping need to be included with the improvements. You need to bring this project through the Minnesota Statute 429 assessment process in a timely manner to construct the project concurrently with the Hennepin County project. Accordingly, we have assigned personnel to this project who understand the public improvement process, the requirements of the Municipal State Aid street system, the needs of Hennepin County, and the adjoining property owners. The following people will be the key personnel assigned to the project: Daniel R. Boxrud, P.E., will serve as project manager and administrator of this project. He will be the primary contact for all parties having an interest in this project. His 24 years of engineering experience have been virtually all related to service to municipalities. Having served seven communities of various sizes as consulting city engineer, Dan understands the 429 process and the needs of the City and the adjoining property owners. Dan has been personally involved in the study, design, and construction of numerous Municipal State Aid streets. John M. Gray, P.E., will be responsible for the traffic signal, signing, and striping aspects of this project. John has experience in the planning, design, and operational concepts of traffic signal systems and development of traffic signal systems involving actuated, coordinated, temporary, and revised systems. He has prepared numerous signal justification reports and signing and striping plans for area communities and counties. Kevin B. Kawlewski, staff engineer, will be involved with the design of horizontal and vertical alignment, storm sewer, and the street pavement section. He has experience in Municipal State Aid street and storm sewer design as well as the preparation of Municipal State Aid construction plans and specifications. Joe Clement, as a registered landscape architect, will be responsible for analysis of the impact of the project on existing landscaping and design of landscaping improvements. Joe also has 8 years experience as a senior engineering technician and currently works with both AutoCAD and Microstation drafting software. Joe will be responsible for fmal construction plans and the landscaping specifications.

PAUL WASECA September 9, 1996 File: 158- 009 -10 Mr. Steve Stadler Public Works Director City of Hopkins 1010 1st Street Hopkins, MN 55343 RE: 11TH AVENUE ANALYSIS - HENNEPIN COUNTY REGIONAL RAIL AUTHORITY TRAIL TO 6TH STREET SOUTH Dear Mr. Stadler: You have requested that MSA analyze a number of existing traffic studies and development plans, and review current information regarding the segment of 1lth Avenue from CSAH 3 to 6th Street. The portion of 11th Avenue from CSAH 3 southerly to the Hennepin County Regional Rail Authority Trail will be included in the CSAH 3 reconstruction project. Therefore, the scope of the analysis that you have asked us to investigate includes possible improvements to 1 lth Avenue from the Regional Rail Authority right -of -way, south to 6th Street. SCOPE You have asked that our work include the following elements: • Review and summary of existing data and reports. • Discussion of existing conditions. • Proposed 11th Avenue roadway and pathway improvements. ■ Estimated preliminary costs for capital improvement budget purposes only. A discussion of each of the items outlined above follows. SUMMARY AND REVIEW OF EXISTING DATA, REPORTS, AND PLAN A description of each item and a brief summary of the results of each report or plan is listed as follows, beginning in chronological order with the oldest document. 1. July 1988 - Benshoof Access Analysis for I lth Avenue South This study was prepared to analyze access for the R. L. Johnson retail /restaurant site located within the southwest quadrant of the intersection of CSAH 3 and 11th Avenue, bounded by the Hennepin County Rail Authority right -of -way on the south, to CSAH 3 on the north. The study evaluated two access alternates for 1 lth Avenue, one with no direct access for the parcel and the other with a right- 1581009- 200I.aug An Equal Opportunity Employer Page 1 158 /009- 2001.aug in/right -out only access with a full median, prohibiting all turns except at the access point. Since the study was completed, this site has been developed and an access provided for the restaurant site on 1 lth Avenue immediately north of the Regional Rail Authority right -of -way. The Hennepin County CSAH 3 plans will incorporate this full access and no median would be provided at the entrance to the Wendy's driveway. Therefore, a full, inbound - outbound access will be provided, allowing turning movements in both the northbound and southbound directions. 2. June 1991 - Barton - Aschman Traffic Access Study for R. L. Johnson Site SE (hladrant of 1 lth Avenue and CSAH 3 This study provided a similar analysis of the proposed restaurant site plan for the R L Johnson site at the southeast quadrant of the intersection. The study also looked at traffic generation from the R L Johnson site south of the Hennepin County Rail Authority right -of -way. Traffic projections were made for the restaurant retail site, as well as the future office /warehouse site. The study concluded that the intersection of CSAH 3 and I lth Avenue South will function adequately upon completion of the proposed development on the two parcels. No geometric improvements were recommended on 1 lth Avenue as a result of the proposed development. This study did note that improvements will be made to the 1 lth Avenue South/CSAH 3 intersection when CSAH 3 is improved, and consideration should be given at that time for some capacity improvements. The recommended access configuration for the site located in the southeast quadrant of the intersection was a single full access driveway on 11th Avenue. This access configuration matches the as -built configuration. Recommended geometric improvements to 1lth Avenue for the site included a northbound right turn lane into the site at the site driveway, and a free right exiting the site northbound on llth Avenue to eastbound CSAH 3. Also, the study recommended a northbound thru -lane and a northbound thru/left turn lane combination with access into the Justus Lumber site. North of this driveway, the recommended improvements included a northbound thru -lane and two northbound left turn lanes to westbound CSAH 3 at the intersection. Final approved plans for CSAH 3 at the intersection of 1 lth Avenue south of CSAH 3 nearly match the Barton - Aschman recommended design with the exception of the two left turn lanes northbound to westbound Instead, the final plans indicate two thru-lanes and a single left turn lane to westbound CSAH 3. 3. January 1995 - HNTB Analysis of R I Johnson Site South of Hennepi Coup Regional Rail Authority Ri -o -w This analysis looked at the R. L. Johnson site south of the Hennepin County Regional Rail Authority right -of -way and analyzed driveway access configuration. The report recommended three driveway access points and analyzed trip Page 2 • 158 /009- 2001.aug generation, the impact of the development on the 1 lth Avenue /CSAH 3 intersection, and also the capacity of 11th Avenue based on the proposed development. The HNTB study concluded that, with the three driveways, development of the Cornerstone Business Center would have no negative capacity impacts on either the intersection of 1 lth Avenue and CSAH 3 or the existing segment of 11th Avenue, south of CSAH 3. February 1995 - Benshoof Review of January 1995 HNTB Study This report analyzed the work done by HNTB to review for the City of Hopkins whether or not the conclusions reached by HNTB regarding development of the R. L. Johnson site south of the Hennepin County Regional Rail Authority right-of- way were reasonable. The Benshoof study reviewed trip generation, driveway access, and trip assignment. The Benshoof study concluded that it is necessary to revise the traffic analysis to account for a potentially higher ultimate land use at the site. Concerns were also raised regarding the internal site circulation and utilization of the site driveways. It was also noted that the traffic assignment split on 11th Avenue, instead of being 50/50 for the site, should be more realistically 80% northbound /20% southbound. Benshoof concluded that a 3 -lane design would perhaps function more efficiently from 6th Street to the Hennepin County Regional Rail Authority trailway. These findings were considered in the City of Hopkins final approval of the R. L. Johnson site plan. 5. 1993 Municipal State Aid Traffic Counts The City provided MSA traffic counts gathered in 1993 for 1 lth Avenue in the vicinity of CSAH 3. South of the intersection, between 5th and CSAH 3, 1993 counts were 13,000 vehicles per day. On the segment south of 5th, between 5th and 6th, traffic was counted at 10,000 cars per day. South of the intersection of 7th, traffic volumes drop off to 9,000 cars per clay on the segment between Westbrook Way and 7th. These were reviewed based on existing development. EXISTING CONDITIONS For purposes of our analysis, we reviewed the existing field conditions of the roadway, including existing width, construction features, and current development. A summary of the roadway widths on the analyzed segment (beginning on the north at the Hennepin County Regional Rail Authority right -of -way and continuing south to the intersection of 6th Street) is as follows: 1. Hennepin Regional Rail Authority right -of -way at a point 60 feet north of 5th Street 44 -foot wide, 4 -lane roadway with concrete curb and gutters and a 5 -foot bituminous path immediately adjacent to the curb on the west side. 2. &point 60 feet north of 5th Street to 6th Street: 48 -foot wide, 4 -lane roadway with concrete curb and gutter. On the west side between 6th Street and 5th Street, a 5 -foot wide concrete sidewalk exists. On the east side, a 5 to 5.5 -foot concrete Page 3 • sidewalk exists beginning at a point approximately 60 feet north of 5th Street and continuing to the intersection of 6th Street. The concrete sidewalk is 5 feet wide except under the railroad overpass where the walk on both sides narrows to 3 feet. 3. South of 6th Street: 44 -foot wide roadway with concrete curb and gutter. The 44- foot wide section continues south to Smetana and generally incorporates a cross - section with two traffic lanes and two parking lanes. A 6 to 8 -foot wide multi -use trail is located on the east side, E x isti ng Development: The Reuter Development is located on the west side of the segment of 1 lth Avenue from the Hennepin County Regional Rail Authority right -of -way, south to 5th Street. This development has four driveways with direct access onto 11th Avenue. Two of the driveways provide direct access to the parking lots and two have direct access to both the building's main entrance and also secondary access to the parking lot. On the east side, the R. L. Johnson site has been developed as the Cornerstone Business Park, a combination office /warehouse facility. This site has three new existing driveways, all of which nearly line up with adjacent driveways on the Reuter property to the west. South of the railway bridge, the Diamond Lab property is currently being developed on the west side. It appears that this site will have one driveway access at 6th Street. On the east side is the existing Super Valu warehouse facility with one major driveway providing direct access onto 11th Avenue. PROPOSED 11TH AVENUE ROADWAY AND PATHWAY IMPROVEMENTS. Based upon our review, we conclude that, because of' new development constraints, the existing roadway cross - section, and a high percentage of truck traffic, roadway improvements appear to be warranted on 1lth Avenue north of the intersection of 5th Street. The 44 -foot section of 1 lth Avenue from the Hennepin County Regional Rail Authority right -of -way to a point approximately 60 feet north of 5th Street should be upgraded. It is also recommended that consistent pathway improvements be considered. We recommend that the improvements include the widening of this section to 52 feet, from face of curb to face of curb. Roadway improvements would include a widening of 4 feet on both sides of the roadway, and would involve removal of existing curb and gutter on both sides from the Hennepin County Trail right -of -way, south to 5th Street. The project would also include removal of the existing bituminous path on the west side and a portion of the existing concrete sidewalk from 5th Street to the north. The construction would involve removal of the existing curb and gutter and bituminous and concrete pathways, excavation and placement of gravel base and material and bituminous base course, uniform milling over the remaining 40 -foot width of bituminous pavement, placement of a wear course over the entire 48 -foot pavement width, and the installation of a new 2 -foot concrete curb and gutter section on each side. The recommended lane configuration upon completion of the improvement would involve four 12 -foot traffic lanes, two in each direction, and a 2 -foot gutter reaction area on each 158 /009- 2001.aug Page 4 side. In addition, the new curb and gutter would provide for new driveway openings which would align on both sides of 1 lth Avenue. We recommend that the northerly driveway to the Reuter parking lot be eliminated, since it serves no useful purpose. We also recommend that consideration be given to possible closure of the middle driveway into the Reuter business since it is not needed. We recommend that the southerly two driveways into the new R L Johnson business park site align with the two Reuter driveways to the west. This could be facilitated by removal of the existing west curb line and driveway aprons, and relocation of the two Reuter driveways. The southerly driveway would need to be moved approximately 15 feet north and the northerly driveway shifted approximately 8 to 10 feet south. With this work completed, the two south driveways would match with driveway access to the west. Right and left turn movements would be provided into all new driveways for businesses on both sides of the intersection between 5th and the Hennepin County Regional Railroad Authority right -of -way. At the intersection of 5th Street in the southbound direction, a right turn and thru- movement would be allowed, as well as a thru- movement from the center lane. In the northbound direction at 5th Street, the right lane could provide for right turns and thru- movements and the left lane would allow left turns and thru- movements After development of all sites along 1lth Avenue is completed, close attention should be paid to accident history at all major driveways. If accidents develop in the future, the 52- foot section could be restriped to provide a protected left turn lane. The lane configuration could then be modified from four 12 -foot lanes and two 2 -foot gutters to a 16 -foot center left turn Iane, two 12 -foot traffic lanes (one in each direction), and a 6 -foot reaction area including a 4 -foot shoulder and 2 -foot gutters in each direction. This section could be installed at any time following a careful review of traffic data and accident history in the future. The 3 -lane configuration would also provide an on -road facility for bicyclists in each direction. For trails, we would note that a regional multi -use trail exists on the east side of 1 lth Avenue south of 6th Street. North of 6th Street, from 6th to 5th, a 5 -foot concrete walk exists on both sides of the street. North of the intersection of 5th Street lies a 5 -foot bituminous trail, immediately behind the curb, and an intermittent concrete walk is located on the east side, to approximately the southerly driveway into the new office/ warehouse site. We believe it is practical to consider extension of a regional trailway from 5th Street, north to the Hennepin County Regional Rail Authority trail. We recommend that this trail would be a minimum of 8 feet and be set back at least 2 to 3 feet behind the curb. The trail should connect to the existing Hennepin County Regional Rail Authority trail and extend southerly to the intersection of 5th Street. At 5th Street, a pedestrian and bike crossing could be incorporated into plans at such time as a signal is installed. The 5 -foot concrete sidewalk on both sides of the street south of 5th Street would remain in place between 5th and 6th. Warning signs should be provided for bicyclists indicating the narrowing of the bikeways /sidewalks under the existing bridge structure. 158 /009- 2001.aug Page 5 ESTIMATED PRELIMINARY COSTS • (for Capital Improvement budget purposes only) • We recommend that this figure be used in the Capital Improvement budget process for setting aside funds for a 1997 construction project. A preliminary estimate of major construction quantities and work tasks for the project described involving the widening of 11th Avenue from 5th Street, north to the Hennepin County Regional Rail Authority trailway is as follows: Removals $ 11,000 Milling 8,000 Curb and gutter, driveway aprons 22,000 Bituminous Paving (4' widening each side, 2" overlay) 36,000 Trailway 18,000 Restoration 5,000 Striping /Signing 4,000 Retaining wall 11 000 TOTAL $114,000 10% contingency 11.400 TOTAL CONSTRUCTION COST $125,400 25 % overhead including engineering, financing, and administrative costs 31.350 TOTAL PROJECT COST $156,750 OTHER IMPROVEMENTS The Capital Improvement Program indicates consideration for a signal being planned for construction at the intersection of 1 lth Avenue and 5th Street. This analysis does not deal with the signal. At the time improvements are considered for 1 1th Avenue, a signal justification report and signal analysis should be completed to determine whether or not a signal is warranted. If a signal is warranted, the construction suggested for 11th Avenue could incorporate the signal either at the same time or at a future date, should immediate conditions not warrant the signal. The 1997 Capital Improvement Program for the City of Hopkins does indicate a signal being constructed at that time For expedient construction, we recommend the signal be included with the 1 lth Avenue roadway improvement project for the segment north of the intersection of 5th Street. Our analysis does not include costs for sanitary sewer and watermain replacement. Since no major removal or reconstruction of the roadway is recommended, we did not believe that improvements to the sanitary sewer and watermain are warranted at this time Any known major operational problems with segments of the sanitary sewer and /or water system may warrant further utility analysis. If this is the case, consideration could be given to a complete reconstruction of the segment in lieu of milling and overlaying. However, the existing surface condition of the pavement does not warrant a complete reconstruction at this time. The improvement recommended is simply to enhance capacity and improve safety because of the high percentage of truck traffic currently using the 158/009- 2001.aug Page 6 • subject segment of 1 lth Avenue. The existing 44 -foot section does not provide adequate lane width for capacity and safe operation, and the 52 -foot wide section will greatly enhance driver safety. We anticipate this information allows you to proceed with your Capital Improvement Program budget for 1997. We recommend that a more detailed feasibility study be completed, analyzing the proposed improvements in greater detail, prior to proceeding with the work. If you have any further questions or wish to discuss the project in greater detail, please contact me. Sincerely, MSA, CONSULT 1 G ENGINEERS St -en D. Gatlin, P.E.
