Cond. Use Permit-A & J Prop.Planning Commission Report - CONDITIONAL USE PERMIT - A & J PROPOSAL August 20, 1986 PURPOSE: To review and recommend action on a Conditional Use Permit request to construct an office /warehouse. BACKGROUND: Name of Applicant: Address of Property: Present Zoning: Nature of Request: Reason for Request: R. L. Johnson Investment Company Fifth Street South & 7th Avenue I -1 To construct a 109,200 square foot office /warehouse Ordinance requires a Conditional Use Permit for construction over $75,000 This proposed construction is the first of four proposed by the ap- plicant. This proposed development will consit of a 109,200 square foot office /warehouse building located at Fifth Street South and Seventh Avenue. The building consists of 80% office and 20% ware- house. I =1 District Proposed Front Yard 75 110 Side Yard N 20 N 50 S 40 S 100 Rear Yard 20 50 Lot Area 10,000 sq.ft. 397,555 sq.ft. F.A.R. .60 .27 Height 35 approx. 17 Parking 344 395 The proposed development complies with the I -1 minimum requirements except the proposed plan shows parking in the front yard setback. The applicant has applied for a variance. The applicant has revised the parking plan since the agenda was de- livered. A few spaces were removed on the inside of the building in the loading dock area, however, the plan still meets the parking re- quirements. Access to the site has been eliminated along 6th Street and there is now proposed three access points along 5th Street. Five loading docks are located on the inside of the proposed build- ing. The proposed plan shows 145 plantings, this exceed the minimum re- quirements. N CUP86 -8 • • • PLANNING REPORT CUP86 -8 Page 2 No drainage plan has been submitted, the applicant believes it .should be ready by the meeting. The applicant has stated that the trash containers will be located in the load- ing dock area. A traffic study has been done for the entire project, which has been enclosed. Basically it was concluded that the current roadway system can handle the traffic for this development. The exterior of the building will be Alucabond fascia with 1 "insulated glass. The applicant has contacted the Watershed District, however as of the date of this report has not received approval. The Fire Marshal was out of town at the time of this report, any approval should be contingent on approval by him. The applicant has not detailed any lighting system for the parking lot, however, all lighting of the parking area will have to conform with the ordinance require- ments. ANALYSIS: The proposed development meets the requirements of the zoning ordinance for the I -1 District and also the requirements for a Conditional Use Permit. The applicant has designed the building to buffer the residential area by placing the access to the building along 5th Street South. Landscaping will also buffer the residential area from the proposed building. The proposed building will provide Hopkins with space to attract new business opportunities. RECOMMENDATION: I recommend approval of the Conditional Use Permit. The following are suggested Findings of Fact should the Commission recommend approval: 1. The development meets the minimum I -1 requirements. 2. The development meets the requirements for a Conditional Use Permit. Conditions: 1. Approval by the Watershed District 2. Approval by the Fire Marshal 3. That the drainage plan be approved by the Director of Engineering. Nancy Anderson, Analyst Communi y Development i BENS HOOF & ASSOCIATES INC.

Johnson Investment Co. FROM: Michael L. Wonson and James A. Benshoof RE: Traffic Study for White Motor Company Redevelopment Proposal The purpose of this memorandum is to document the analysis and findings of our traffic study concerning the redevelop- ment proposal on the White Motor Company property in the City of Hopkins. Principal issues which have been addressed include: . The impact of development traffic on the public roadway system in general and effects of development traffic on the capacity of key area intersections during the P.M. Peak Hour. The P.M. Peak Hour is the time during which traffic volumes on the roadway system are heaviest and thus the time during which the impacts of development traffic would be greatest. . Effects of development traffic (particularly Phase I traffic) on residential streets east of llth Avenue South and south of 6th Street South. Figure 1 presents the concept plan, which we understand has been modified slightly. The proposal consists of the development of four separate properties: . Site A consists of 109,200 sq. ft. of office /warehouse space (80% office /20% warehouse), located south of 5th Street South, west of 7th Avenue South. Access is currently proposed only from 5th Street South, with no access directly to 6th Street South. . Site B consists of 218,400 sq. ft. of office /warehouse development located east of 1lth Avenue South, west of Knox Lumber. Access is proposed from 11th Avenue South as well as via - a railroad crossing and "frontage road" to the existing intersection of 8th Avenue South and County Road 3. NOTE: Current plan has no .access to 6th St and one ;more access to 5th St i SIXTH STREET Concept Plan by Rieke Carroll Mueller Associates R.L. JOHNSON INVESTMENT CO. INC. BENSHOOF & ASSOCIATES, INC. TRANSPORTATION AND LAND USE CONSULTANTS TRAFFIC STUDY FOR WHITE MOTOR COMPANY REDEVELOPMENT PROPOSAL • Mr. Constable -3- August 19, 1986 • Site C contains a car care center of 26,800 sq. ft. with access to both 11th Avenue and 8th Avenue /County Road 3 via the "frontage road ". • Site D has no specific concept plan at this time, but is proposed to contain approximately 25,000 sq. ft. of service /retail development. It is expected that the principal access to this site would be from 9th Avenue South, north of County Road 3, with no direct access either to County Road 3 or Ilth Avenue South. The current phasing plan for development of the four sites calls for occupancy of site A in 1987, site 6 in 1988, and sites C and D by the end of 1989. The three principal roadways providing access to the sites are County Road 3, Ilth Avenue South, and 5th Street South /6th Street South. County Road 3 is a designated minor arterial and is a four lane roadway with turn lanes at signalized intersections at 5th Avenue South, 8th Avenue South, and Ilth Avenue South. Traffic currently is effec- tively accommodated at these intersections, with the greatest traffic volumes occurring at Ilth Avenue princi- pally as a result of high approach volumes from the south. This intersection currently operates at a level of service D during the P.M. Peak Hour, an acceptable level of service for an urban intersection. Level of service reflects the effectiveness of traffic operations at an intersection and ranges from A to F. Level of service A indicates an uncongested operation, while level of service F indicates that the traffic volumes through the intersection exceed its capacity, with resultant congestion and delay. Ilth Avenue South is a designated collector roadway, generally 44 feet in width. Turn movement counts and traffic observations were performed at the intersections of 5th Street South /11th Avenue and 6th Street South /11th Avenue during the P.M. Peak period (4 P.M. to 6 P.M.). The intersection at 5th Street operates effectively, with the exception of left turns from the west to the north which currently operate at a level of service F. P.M. Peak Hour volumes at this intersection do not quite meet warrants for signalization. At 6th Street South, a three way stop controlled intersection, observations indicated effective traffic flow with minimal queuing on the 6th Street approach. This intersection also does not currently meet signal warrants. Mr. Constable 6th Street /5th Street is generally a 44 foot roadway and is a designated State Aid road. The intersection of 6th Street /5th Street /10th Avenue South currently is poorly designed given the skewed angles at which roadways merge. As we understand it, concern has been expressed regarding westbound vehicles on 5th Street utilizing 10th Avenue South (a residential street) to bypass the intersection of 6th Street /11th Avenue South. TRAFFIC FORECASTS Development Traffic -4- August 19, 1986 The first step in the traffic forecasting process is to estimate trips generated by the proposed development. The following table presents the trip generation expected from each component of the development. For the office /warehouse and retail components, trip generation rates published by the Institute of Transportation Engineers were utilized. For the car care center, trip generation rates established for a similar project in the City of Eagan by Benshoof & Associates, Inc. were utilized. DEVELOPMENT TRIP GENERATION Daily Trips P.M. Peak Hour Trips Site Use (Two Way) In Out A Office/ 1,180 40 188 Warehouse B Office/ 2,360 81 376 Warehouse Car Care 960 50 50 Center D Service 1,850 85 90 Retail Total 6,350 256 704 Distribution of trips to /from the development was estimated based upon a variety of factors including existing turn movements, previous studies by Benshoof & Associates, Inc. for the Oakwood Hills residential project in Hopkins and for studies in the Opus 2 area, previous studies by BRW Inc., and Metropolitan Council regional forecasts.

N Sites 0 1200 Approximate Scale 0 U Mr. Constable -6- August 19, 1986 Based upon the expected trip generation and distribution, development trips were assigned via the most convenient direct route to /from their destination. In certain instances, multiple routings were utilized. For example, for trips from Site B to /from the south on County Road 18, a portion were assigned via Ilth Avenue and 6th Street /5th Street to the 5th Street interchange; a portion were assigned via Ilth Avenue and County Road 3; and a portion were assigned via 8th Avenue and County Road 3. Through this assignment process both average daily traffic and P.M. Peak Hour turn movements for full development of the four sites (1989) were determined. Other Area Traffic In order to assess the impacts of development traffic in 1989, it is necessary to account for growth in other area traffic. For average daily traffic volumes, in general, 1985 MSA counts were factored upwards by 2.5% per year (the average growth factor in the area). Added to the adjusted 1989 volumes was traffic associated with the Conservatory and Oakwood Hills residential developments. For the P.M. Peak Hour volumes, existing turn movement counts taken at 6th Street /11th Avenue (August 8, 1986) and 5th Street /11th Avenue (August 13, 1986) were factored upwards by 2.5% per year and the Oakwood Hills traffic added. For the intersections along County Road 3, turn movement counts prepared by Hennepin County were adjusted to 1985 volumes; these volumes were factored to 1989 and Oakwood Hills /Conservatory traffic added. These adjusted other traffic volumes were added to the projected full development volumes to obtain estimated 1989 volumes upon completion of all four development phases. TRAFFIC ANALYSIS Figure 3 presents projected 1989 average daily traffic volumes both with and without the proposed development. In general, the post development volumes are consistent with the function of the affected roadways indicating that on a daily basis the development traffic can be effectively accommodated. The largest increase in daily traffic associated with the development occurs on Ilth Avenue South just south of County Road 3. The projected volume is approaching the upper levels of daily volumes typically carried by collectors, suggesting some roadway improvements may be necessary. A more specific analysis of the impacts of development traffic focuses on the P.M. Peak Hour during which other traffic volumes are highest and thus development traffic impacts potentially the greatest.

TRANSPORTATION AND LAND USE CONSULTANTS TRAFFIC STUDY FOR WHITE MOTOR COMPANY REDEVELOPMENT PROPOSA PROJECTED 1989 AVERAGE DAILY TRAFFIC 1 Mr. Constable -8- August 19, 1986 Figure 4 presents the 1989 P.M. Peak Hour forecasts at key area intersections both with and without development traffic. At the intersection of 6th Street South and Ilth Avenue, the analysis indicates that the intersection will operate at a level of service C during the P.M. Peak Hour upon full development of the proposal. This level of service indicates that development traffic can be accommodated with no negative impacts. The projected volumes do meet peak hour signal warrants, indicating a signal could be installed at this location even though the level of service is C. It is recommended that this intersection be monitored, and, if appropriate, a signal installed. At the intersection of 5th Street and Ilth Avenue South, left turns from 5th Street will continue to operate at a level of service F unless a signal is installed. The 1989 projections indicate that signal warrants are met without development traffic. As such, the addition of the development traffic is not expected to significantly affect intersection operation. This intersection should continue to be monitored to allow signal installation when warrants are met. It would also be desirable to realign 5th Street to the north opposite the southerly access point to Site B. This would provide the benefits of creating one four way intersection, as opposed to two T intersections, and of improved egress for Site B. Along County Road 3, the capacity analyses indicate that the intersections with 5th Avenue South and 8th Avenue South would operate at levels of service C and B with full development of the proposal. These levels of service are highly acceptable and indicate that the intersections can effectively accommodate development traffic. At the intersection of County Road 3 and Ilth Avenue South, the analysis indicates that the intersection will operate at a level of service E without this development. A level of service E indicates that congestion and delay will occur, principally as a result of the high traffic volumes on the south approach. As such, even without development traffic roadway improvements will be necessary. Development traffic would increase peak hour traffic congestion and would result in a level of service F. 11TH AVE S / CO.RD. 3 66/66 936/1154. .

JOHNSON INVESTMENT CO. INC. BENSHOOF & ASSOCIATES, INC. TRANSPORTATION AND LAND USE CONSULTANTS -J- Mr. Constable -10- August 19, 1986 A number of alternative conceptual roadway improvements were analyzed to improve intersection operations. While minor modifications to the north and south approaches (two full approach lanes and an exclusive left turn lane /left - through lane respectively) could allow the intersection to operate at a level of service E with the addition of development traffic (identical to the level of service without develop - pment traffic or improvements), level of service E is generally not acceptable and intersection operation could be expected to deteriorate beyond 1989. As such, the analysis focused on a solution which would allow the intersection to operate at a level of service D. This solution concentrates improvements on the south approach, which, based on the projections, would carry the highest volumes of the four approaches. The concept entails widening 11th Avenue to 52 feet from County Road 3 through the 5th Street South intersection to create a full four lane roadway. On the south approach to County Road 3, the road way would have four lanes: a right turn lane, a through lane, a through -left turn lane, and an exclusive left turn lane. Widening would also be required on the north leg of 11th Avenue to construct 2 full lanes in each direction. This widening could be tapered to the existing 44 foot width of llth Avenue in the vicinity of City Hall, south of 1st Street South. These improvement would allow the intersec- tion to effectively accommodate both development traffic and other area traffic at a level of service D. As noted, these improvements are necessary with or without the proposed development. As such, it is recommended that the City continue to monitor traffic volumes at this inter- section. If volumes increase as projected, the City should take appropriate steps to design and implement roadway improvements in conjunction with Hennepin County. INTERSECTION OF 5TH STREET /6TH STREET /10TH AVENUE SOUTH As noted, the current design of this intersection creates the potential for traffic conflicts and may promote use of 10th Avenue South for traffic proceeding south on llth Avenue. It is not expected that Site A of the proposed development will significantly increase usage of 10th Avenue. However, it is appropriate that the City take steps to remedy the existing geometrics.

FOR 5TH AND 6TH- ST INTERSECTION Mr. Constable T intersections and eliminating the difficult angle on the east approach of 6th Street. This concept will require additional right -of -way from Site A; however this right -of- way would be located on the "undeveloped" corner of the site. As noted, the City could take action to prohibit left turns to the south on 10th Avenue through either signage or construction of a center island on 5th Street /6th Street. SITE ACCESS As we understand it, only site A is currently proposed for development and the plans shown for sites B and C are conceptual only. As such, the specific location and design of the access points for sites B and C should be analyzed as specific site plans for those properties are prepared. Concerning access for site A, as noted no access to 6th Street South is currently proposed. This situation is appropriate as it significantly reduces the potential of usage of residential streets south of 6th Street by development traffic. Three access points to 5th Street South are proposed. The access location just west of 7th Avenue South is necessary to ensure viable truck access to the site and avoid on site traffic conflicts. Given the expected limited usage of this access point and limited turn movements at 7th Avenue South, it is expected that this access will function effectively. Regarding the other access points to 5th Street, one should be located either directly across from the existing access to the Super Valu warehouse or offset a minimum of 150 feet centerline to centerline to eliminate turn movement conflicts. CONCLUSIONS -12- August 19, 1986 Based upon the analysis of the traffic impacts of the proposed development, the following conclusions are made: • Traffic associated with development of Site A (Phase I) can be effectively accommodated by the public roadway system. • Upon completion of the full proposal (1989), the public roadway system can effectively accommodate development traffic provided that appropriate improvements are implemented at the intersection of County Road 3 and 11th Avenue South. Mr. Constable -13- August 19, 1986 At County Road 3 and 11th Avenue, the intersection is expected to operate at a level of service E, a generally unacceptable level of service, without the addition of development traffic. The operation of the Intersection would be expected to deteriorate through time as other development /redevelopment of the area occurs. This analysis indicates that the operation would be at level of service F with development traffic in 1989 unless improvements are implemented.The City should monitor this intersection and, if volumes in- crease as projected, take steps to implement roadway improvements. These improvements should focus on in- creasing the capacity of the south approach on 11th Avenue. ▪ Upon full development, the intersection of 6th Street South and 11th Avenue South is expected to operate at a level of service C. Projected volumes indicate that signal installation will be warranted. It is recom- mended that the City monitor this intersection to determine whether signalization will improve inter- section operation. • At the intersection of 5th Street South and 11th Avenue projected volumes indicate a signal will be warranted without the addition of development traffic. The City should monitor thi$ intersection to allow signal installation when warrants are met. Signal install- ation will improve intersection operation, specific- ally left turns to the north on 11th Avenue. • While development traffic is not expected to signif- icantly affect the intersection of 6th Street /5th Street /11th Avenue South, the City should take steps to redesign this intersection and possibly prohibit turn movements from the north on 5th Street to the south on 10th Avenue. o-..., w. 10.8 Zo 1 .ice' ^. •�.....�w+ ��r rsss E �_ CI 5th STREET.
