SUBJECT: Audubon Road Reconstruction Project No. 10-02: Public Hearing; Authorize Preparation of Plans and Specifications PROPOSED MOTION "The City Council is recommended to hold the public hearing for the Audubon Road Reconstruction Project No. 10-02 and authorize the preparation of plans and specifications. City Council approval requires a simple majority vote of the City Council present. " BACKGROUND On July 13 2009, staff discussed the proposed 2010 street reconstruction projects with the City Council at the work session. On August 10,2009, City Council awarded the preliminary design consultant contract to SRF Consulting Group, Inc. (SRF). A neighborhood open house was held December 2, 2009 to discuss the project with the property owners that are proposed to be assessed. An open house for the neighborhood was held on January 13,2010. SCOPE OF PROJECT Street Improvements Audubon Road from Lake Drive West to Lyman Boulevard (CSAH 18) is a municipal collector roadway and is proposed to be reconstructed this year. The pavement is in poor condition and shows severe pavement distress. The average pavement condition indices (PCI) range from 17 to 40 with the average being 31; a road at 45 PCI typically indicates distress that would require a full depth reconstruction. The roadway is a rural section with gravel shoulders. The gravel shoulders on the hill washout frequently and become a hazard to the traveling public. The shoulders are also a maintenance concern for staff. The proposed urbanization of the street and the storm sewer installation will eliminate this problem. Chanhassen is a Community for life - Providing for Today and Planning for Tomorrow Paul Oehme Audubon Road Reconstruction Project February 8, 2010 Page 2 Audubon Road is proposed to be urbanized and turn lanes added for safety. The corridor is not proposed to be widened but improved to about the current width of the pavement section when the gravel shoulders are included. Most intersections already have substandard right turn lanes. Left turn lanes are proposed to be added at most intersections. A common center left turn lane is proposed to be added at the south end of the corridor for residential driveway access. Turn lanes would be expensive to install in the future iftraffic problems were to increase. The traveled thru lanes are proposed to be 14' wide in most areas and 12' wide at some intersections. Staffis proposing to keep the width of the thru lanes narroW as a traffic calming technique. The intersection at Valley Ridge Trail North/OspreyLane is proposed to be 52 feet to accommodate the left turn lanes and right turn lane improvements. This intersection is currently 48' wide. Trail Improvements A 10-foot wide trail is proposed to be extended on the west side of Audubon Road from Valley Ridge Trail North to Lyman Boulevard. The trail is proposed to be off road and in back of the curb for safety considerations. The Parks Department Trail Comprehensive Plan identifies this trail as an important connection. The trail's anticipated use may include recreation, transportation, a non- motorized route for workplace commuting and a training route for high school athletic teams. Completion of this trail will allow residents in the area the opportunity to create looping routes for their walks and other trail recreation activities. Looping routes are much preferred over out-and- back routes. The trail will also connect to the future trial on Lyman Boulevard east of Audubon Road. Staff has looked at the pros and cons to construct the trail on both sides of Audubon Road and is recommending the trail be constructed on the west side. If the trail would be extended on the east side, a significant stand of mature trees would need to be removed, extensive grading would be necessary and a retaining wall would need to be constructed. A driveway would also need to be relocated or replaced to accommodate the trail. Additional permanent easements would also be required. Installing the trail on the west side of the road utilizes a superior trail corridor, requires significantly less financial investment and puts the trail on the side of the road with the densest residential development. These residents will benefit by being afforded a second convenient access to the City's trail system (the first being the connection to the Bluff Creek Trail). An at-grade pedestrian trail crossing is proposed at the Valley Ridge Trail North/Osprey Lane intersection. Other pedestrian crossing locations were also evaluated however the Valley Ridge Trail North crossing location appears to be the best location because it: . Provides the best trail connectivity, in particular to the north. . Is anticipated to be were most pedestrians would want to cross based on destination. . Offers the best sight lines for vehicles to see the crossing. If sufficient pedestrian traffic exists, a mid-block crossing location with refuge island could be considered in the future. Depending on the actual pedestrian routes, future consideration could be given to a crosswalk being located on the south side of Heron Drive, since it is "shadowed" by the southbound left turn lane. Also, it is legal for pedestrians to cross at any intersection with either a g:\eng\public'-201O proj ects\ 1 0-02 audubon road imp\02-08-10 public hearing.docx Paul Oehme Audubon Road Reconstruction Project February 8, 2010 Page 3 marked or unmarked crosswalk. If residents feel more comfortable crossing at another intersection, they can cross at a different location. A small area of land will need to be acquired at the south end of Audubon Road to accommodate the trail. Most of the acquisition is planned to be temporary construction easements. The appraisals for the property are almost complete. Some small trees and brush will need to be removed. Staff will work with the property owners on a landscape plan as part of this project. Storm Water Management The pond on the south side of Lyman Boulevard was oversized in conjunction with the Lyman Boulevard reconstruction project to treat the runoff from the southern % of this segment of Audubon Road. A storm sewer pipe was stubbed to the north side of Lyman Boulevard for the future reconstruction of Audubon Road. The oversizing was designed based on Audubon Road being reconstructed to a 44-foot wide road. Runoff from the northern 'l4 of the project area is proposed to be treated in the existing storm water pond on the southeast comer of Lake Drive West and Audubon Road. A new storm sewer pipe outlet will be needed to this pond. The City has an easement over this pond so no additional easements are anticipated. Curb and gutter is proposed to be added for safety due to the proposed trail on the back side of the curb and to direct the roadway runoff to the catch basins. A box culvert for Bluff Creek is located at the southern end of the project area to convey flow under Audubon Road. SRF reviewed the existing structural integrity of the box culvert and determined that it is in good condition. The box culvert must be extended in conjunction with the trail construction. The proposed location of the box culvert extension is under a drainage and utility easement. Utility Improvements A 12-inch diameter trunk watermain is within the western right of way of Audubon Road. There are no records ofwatermain breaks in the project area. The gate valve and hydrant bolts within the corridor are proposed to be replaced. Some hydrants will need to be relocated in conjunction with this project. Water services are proposed to be extended to properties along Audubon Road that do not already have water service. These improvements are proposed at this time because it would be more cost effective to make these improvements at the time the road is being reconstructed. The water service extension is proposed to be assessed back to the benefiting property owners as an optional improvement. The estimated cost for this improvement is $ 1, 175/unit. A sanitary forcemain exists under this portion of Audubon Road. The gate valve bolts to the forcemain are proposed to be replaced. The gravity sanitary sewer within the project corridor has been televised and appears to be in good condition; therefore no sanitary sewer improvements are proposed. g:\eng\public\)OlO projects\lO-02 audubon road imp\02-08-1O public hearing.docx Paul Oehme Audubon Road Reconstruction Project February 8, 2010 Page 4 Private Utilities The electric, telephone and cable lines are overhead through most of the project corridor. Due to the capacity of the electrical lines, Xcel has indicated power lines cannot be buried. It is anticipated many ofthe utility poles would need to be relocated with this project. Staff does not have a plan from Xcel at this time if and where the poles will be moved. A petroleum pipeline crosses under Audubon Road near Valley Ridge Trail South. The road is proposed to be lowered approximately 'li foot at this location. Staff has been in contact with this utility company regarding this project. Street Lighting Additional intersection street lights are proposed at the Osprey Lane, Valley Ridge Trail South and Sunridge Court for safety. No additional street lights are proposed along the corridor at this time. Residential Feedback and Concerns A neighborhood open house for the residents proposed to be assessed was held on December 2, 2009. Approximately 12 residents representing seven properties attended. The following summarizes the residents' questions/issues: . Audubon Road is a neighborhood road and should not be constructed as proposed. . Why is the road proposed to be widened? Can't it remain the existing width? . The speed limit is too high. Can it be lowered? . Why is the City proposing a trail from Valley Ridge Trail North to Lyman Boulevard? . Why is the trail proposed on the west side? . Can the proposed pedestrian trail be moved to another location? . Who will maintain the trail and pick up the trash? . What is the traffic volume? . There is too much truck traffic is on Audubon Road. Can trucks be prohibited? . We want an all-way stop at the Valley Ridge Trail North/Osprey Lane intersection. . Will trees be removed? . Will street lights be installed? . Will a traffic light be installed at the Lyman Boulevard intersection? . Will I have access to my property during construction? . Can the overhead utilities be buried? A second open house was held on January 13,2010. Notices were mailed to residents of the Valley Ridge neighborhood and property owners adjacent to the project corridor. An ad was placed in the Chanhassen Villager inviting the general public to the open house. Approximately 40 or 50 residents attended. The concerns were similar to those brought up at the December 2, 2009 open house. A project summary sheet with common questions and staff comments to the questions were distributed at the January 13, 2010 meeting and is also attached to this background. This information is also posted on the City's website. g:\eng\public'-2010 projects\lO-02 audubon road imp\02-08-10 public hearing.docx Paul Oehme Audubon Road Reconstruction Project February 8, 2010 Page 5 The two biggest concerns staff heard from the residents was the posted speed limit is too high and the amount of truck traffic. The speed of Audubon Road is posted 45 mph and is not planned to change. The Minnesota Department of Transportation sets the speed limits for public streets which is stated in Minnesota State Statue 169.14. It is unlikely the State of Minnesota would lower the speed limit because this corridor would not meet the requirements for lowering the speed limit. Staff has met with State officials to discuss this issue and the State indicated it would need to follow its guidelines in this situation. If Audubon Road is reconstructed staff will be taking additional speed counts to document any changes. Audubon Road is a MSA (Municipal State Aid) route and truck traffic is accommodated on these types of roadways. The 2030 Comprehensive Plan designates Audubon Road as a collector roadway. There is no way to completely stop truck traffic from accessing this route due to the configuration of the road. State Statue 169.80 and 169.87 stipulate the truck load requirements for roadways. Minnesota Department of Transportation Technical Memorandum No. 94-SA-11 clarifies the statues which states cities cannot restrict truck traffic on roadways that meet design standards. Staff took traffic counts on August 10,2009 which indicate 3 % of the traffic is made up of 3 -axle vehicles or larger. Staff could contact the businesses along Audubon Road to discuss truck routes and traffic. PROPOSED FUNDING AND ESTIMATED ASSESSMENTS The estimated costs for the Audubon Street Reconstruction Project No. 10-02 from Lake Drive West to Lyman Boulevard are $2,760,000. A 15% construction contingency, 15% for indirect costs and estimated inflation are included in the estimate. Special assessments to the benefitting properties are proposed to pay for a portion of the street costs associated with this project. The remaining street costs are proposed to be paid from the sale of municipal bonds. The preliminary funding is as follows: Funding Source Sale of Municipal Bonds Street Assessments Water Service Assessments Amount $2,703,765 $50,360 $5,875 $2,760,000 The proposed Audubon Road reconstruction project is unique in that the proposed street is wider than a typical residential road and driveway access to Audubon Road is limited due to the higher traffic volumes and speed. This results in a higher street reconstruction cost and fewer benefitting properties than a typical street reconstruction project. This issue is however no different than other streets the City has recently reconstructed. Examples of other streets the City has reconstructed that were wider than the typical residential street are Laredo Drive, W. 78th Street and Lake Lucy Road. To compensate for this difference and to be consistent with past reconstruction project assessment methodology, staff proposes the following: 1. The amount to be assessed is based on a 31- foot wide street, and 2. The number of benefitting units assumes 90-foot wide lots on both sides of Audubon Road: 8,500 frontage feet -;- 90 front feet/benefitting unit = 94.4 benefitting units g:\eng\public'-2010 projects\1O-02 audubon road imp\02-08-10 public hearing.docx Paul Oehme Audubon Road Reconstruction Project February 8, 2010 Page 6 The following graphic illustrates the proposed assessment methodology and estimated unit assessment: If Audubon Road were a local street, there would be 90' wide lots on each side of the road.

Total Project Cost: $3,000,000 2010 - Audubon Road Lyman Blvd, to Lake Drive West Justification The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. Rehabilitation projects extend the life of the street. In cases with utility or poor sub grade needs to be replaced or where streets have deteriorated to a point where rehabilitation will no longer be practical, reconstruction of the street is necessary. A feasibility study is written to consider the merits of the project and scope of work.

N .-l ,.;- CITY PROJECT 10-02: AUDUBON ROAD RECONSTRUCTION (Lake Drive to Lyman Boulevard) Project Information The project would reconstruct Audubon Road from Lake Drive West to Lyman Boulevard. The proposal includes the installation of turn lanes, concrete curb and gutter and storm sewer. Intersection lighting is planned as a safety improvement. A 1 O-foot wide bituminous trail is proposed to be constructed on the west side from Valley Ridge Trail North to Lyman Boulevard. General Questions Received About the Project 1. Will Audubon Road be wider? .> In most segments of the roadway the proposed design will be about the same width as the current width when the gravel shoulder is included. Proposed left turn lanes at some intersections would increase the width. 2. Why is the City proposing a trail on this segment of road? .> The trail on Audubon is proposed for construction to complete an important missing link. in the Cities Trail System. The 2030 Comprehensive plan identifies this segment as a key pedestrian connector within the community. Upon completion anticipated uses include recreation, transportation, a non-motorized route for workplace commuting and a training route for high school athletic teams. Completion of this trail will allow residents in the area the opportunity to create looping routes for their walks and other trail recreation activities. Looping routes are much preferred over out and back routes. . 3. Why is the City proposing to construct the trail on the west side of Audubon Road when the trail is stubbed on the east side? .> Several factors have lead to this recommendation. If the trail would be extended on the east, a significant stand of mature trees would need to be removed, extensive grading would be necessary and a retaining wall would need to be constructed. A driveway would also need to be relocated or replaced to accommodate the trail. Additional permanent easement would also be required. Installing the trail on the west side of the road utilizes a superior trail corridor, requires significantly less fmancial investment and puts the trail on the side of the road with the densest residential development. These residents will benefit by being afforded a second convenient access to the Cities trail system (The first being the connection to the Bluff Creek Trail). 4. Can the Audubon Road pedestrian trail crossing at Valley Ridge North be moved to Valley Ridge South? Valley View Ridge Trail North . Provides the best trail connectivity, in particular to the north. . Minimizes pedestrian travel to cross Audubon Road. . Good sight lines f?r vehicles to see the crossing. . Pedestrians have a wider roadway to cross (through and turn lanes). Valley View Trail South . Crossing on the north side would provide a pedestrian refuge ("shadowed" by the northbound left-turn lane). . Less pavement for pedestrians to cross. . Additional construction costs and private property acquisition. . Concern about sight lines, driver's ability to see the crossing. . It is legal for pedestrians to cross at any intersection with either a marked or unmarked crosswalk. Recommendations: . The proposed crosswalk location at Valley Ridge Trail North provides the best trail connectivity and travel distance. . If sufficient pedestrian traffic exists, a mid-block crossing location with refuge island could be considered in the future due to the vehicular speeds. . Depending on the actual pedestrian routes, future consideration could be given to a crosswalk being located on the south side of Heron Drive, since it is "shadowed" by the southbound left. turn lane. 5. Who will maintain the area around the trail and pick up the trash if the trail is constructed? ~ The Cities Trail System is maintained by our Public Works Division. Maintenance activities include mowing, sweeping and snow removal. The City coordinates trash collection along roads through local volunteers, community service workers and sentenced to service workers. 6. Does the City know how much vehicle traffic uses Audubon Road? :> Traffic counts were taken by the city on August 10, 2009 and show 3,200 trips per day. The state counts for 2009 show 2,900 trips per day. 7. How much truck traffic is on Audubon Road? ~ The August 10,2009 traffic counts that were taken indicate 3% of the traffic is made up of3 axle vehicles or large. 8. Can truck traffic be discouraged from using Audubon Road south of Lake Drive West? :> Audubon Road is a MSA (Municipal State-Aid) route and truck traffic is accommodated on these types of roadways. The 2030 comprehensive plan designates Audubon Road as a collector Roadway. There is no way to completely stop truck traffic from accessing this route do to the configuration of the road. :> Some solutions may include: 1. Provide a more convenient route for the truck traffic. Logistically, businesses are going to select the shortest/fastest routes to transport their goods. ii. Staff could contact the businesses to discuss truck routes. 9. Can stop signs be installed at all the intersections? All-way stop control warrants are found in .the MnMUTCD (Minnesota Manual of Uniform Traffic Control Devices). While there are several criteria, the main criteria include safety and operations of the intersection. In this situation, the following can warrant All-Way stop control: . Four crashes within a 12-month period which would be correctable by all-way stop control (right- turn, left-turn and right angle crashes) . Minimum Traffic Volumes o 210 vehicles per hour on Audubon Road for eight hours and 140 vehicles per hour on the cross- street for the same hours . Other criteria as determined in an engineering study (sight distance, etc.) Crash data was reviewed for the past five years. The following are the number of reported crashes in the Mn/DOT database: . Lake Drive: 3 crashes (three right angle, all were property damage only) . Huron Drive: 2 crashes (one rear-end, property damage only; one ran-off road non-incapacitating injury) . Valley Ridge Trail North: 1 crash (ran-off road, property damage only) . Valley Ridge Trail South: 0 crashes . Sunridge Court: 0 crashes Unwarranted All-Way Stop Control: . Unwarranted installation can actually cause more safety and operational problems even though done with good intebsions. The following are some findings from studies about installing unwarranted A11- Way Stop Control. · All-Way Stops do not control speeds. In fact, speeds typical increase away from the intersection. Other elements should be considered to calm traffic speed if that is the real concern. . Stop compliance is poor at unwarranted all-way stop control intersections. . Safety of pedestrians can actually decrease, because pedestrians expect vehicles to stop while vehicles become accustomed to "running" the unnecessary/unwarranted stop sign because they never "stop" for cross-street traffic. · 'J'!1e city may incur high li~bility exposure by ''violating'' the MnMUTCD. Recommendations: . Based on the MnMUTCD none of the intersections in the project area are recommended be controlled by all-way stop control. ~:; . In the future at the Lake Drive West intersection could have improvements made to calm the traffic in this area if warranted. . ,) 10. Will trees need to be removed? > A few trees will need to be removed along the corridor especially in the temporary easement locations at the south end of the project. Trees will be replanted in the temporary easement locations. 11. Will street lights be added along Audubon Road? > Additional intersection street lights are proposed at the Osprey, Valley Ridge Trail South and Sunridge Court for safety. 12. Will I have access to my property during construction? > Access will be provided to your property during construction. Audubon road however will be closed to through or none local traffic. 13. Can the overhead utilities be buried? a. Xcel has indicated that the utility power lines cannot be buried because of the size of the line. The power poles may need to be relocated. 14.

To effectively enforce a law the public must believe that the law is ' reasonable. Minnesota's speed regulations are based on the same Basic Speed Law that is used in all 50 states: "No pers~n shall drive a vehicle on a highway at a speed greater than IS reasonable and prudent under the conditions". Statutory limits are based on the concept that uniform categories of highways can operate safely at certain preset ~a~iI?um speeds under ideal conditions. Whether the speed hmlt IS posted or unposted, drivers are required to reduce speed below these values for poor weather conditions curves or hills and potential hazards such as pedestrians. D:ivers must also reduce speed when approaching or passing emergency vehicles with emergency lights flashing. These are the most common statutory speeds: .J 10 mph in alleys .J 30 mph on streets in urban districts .J 70 mph on rural interstate highways .J 65 mph on urban interstate highways .J 65 mph on expressways .J 55 mph on other roads Whenever these statutory speed limits are not the correct value for a specific highway, the commissioner of transportation authorizes the posting of other regulatory speed limits. + JfIa- Interstates are high design multi-lane divided highways that have controlled access interchanges such as cloverleafs or diamond shaped interchanges, Through traffic on the Interstate never has to stop or yield, Examples: 1-94 or 1-35 Expressways are multi-lane divided highways but they have e~tries and inter~ections, sometimes controlled by traffic signals, Some Interchanges may exist but they are not the ruie. Examples: Highway 10 or Highway 52 How Does Mn/DOT Determine the Regulatory Speed Limit? ~h~ commissioner of transportation sets regulatory speed hmlts on state and local roads based on a thorough engineering and traffic investigation. These factors are considered: .J road type and condition .J location and type of access points (intersections, entrances, etc.) .J sufficient length of roadway (1/4 mile minimum) .J existing traffic control devices (signs, signals, etc.) .J crash history .J traffic volume .J sight distances (curve, hiIl, etc.) .J test drive results .J speed study The most important part of the traffic investigation is the speed study. When choosing a speed, drivers take many roadway environment factors into consideration. Therefore, the speed that the majority of people consider prudent is an important value. Data is collected by perfom1ing radar checks at selected locations on the roadway under ideal driving conditions. A technical analysis is done on the results to determine the 85th percentile. This is the value indicating the speed at which most (85%) drivers are traveling under. Experience has shown that a posted speed limit near this value is the maximum safe and reasonable speed. Studies have shown that traveling much faster or slower than this value can increase your chance of being in a crash. Engineering judgement is an important tool. The traffic investigator must use knowledge of nationally accepted principles combined with experience to assign the safe speed. ,\\NESOr ()(~ 1'11< August 2002 !! '(: Minnesota Department of Transportation 1 /:0 Office of Traffic Engineering & ~ jf Intelligent Transportation Systems r OF Tl'~"'<; M"'''J Minn",/4 www.dot.state.mn.us/trafficeng What are the Types of Speed Limits? REGULATORY SPEED LIMIT SIGN SPEED LIMIT 50 This black and white sign shows the maximum speed that a motorist may travel under ideal conditions. It can be a statutory value or else it must be authorized by the commissioner of transportation. ADVISORY SPEED SIGN ~ This black and yellow speed sign is used to advise motorists of a comfortable speed to navigate certain situations. It is used with a warning sign. For instance, when traveling on a winding road, the curve 1251 warning sign would be used with an advisory speed sign. This sign may be posted by the local road MPH authority on local roads. SPEED LIMITS IN SCHOOL ZONES ISCHooL! SPEED LIMIT 20 I~al Local authorities may establish school speed limits on local streets, within a school zone, upon the basis of an engineering and traffic investigation as prescribed by the commissioner of transportation. This regulatory speed limit is in effect whenever children are present, such as before and after school or during recess. The school plate is black and yellow and the other signs are black and white. Optional flourescent yellow green may be used for the school plate. SPEED LIMITS IN WORK ZONES + . - SPEED LIMIT 40 SPEED LIMIT 5Q Advisory speed limits are used to identify safe speeds for specific conditions within a work zone. These black and orange signs are always used with warning signs. The local road authority can post these plates in work zones on local roads. Work zone speed limits are short term regulatory speed limits that are established for worker safety due to traffic in adjacent lanes. These speed limits range from 20 mph to 40 mph on two lane-two way roads and up to 55 mph on divided highways. They can be posted by the local road authority in active work zones on local roads. The FINES DOUBLE plate is black and orange and the speed limit sign is black and white. Temporary speed limits in construction zones are sometimes needed for long term construction projects or detour routes. These regulatory black and white signs are used when a reduced speed is needed for -driver safety. valid 24 hours a day, 7 days a week, these must be authorized by the commissioner of transportation for any roadway. See the website: www.dot.state.mn.us/speed for more information o'!.."Work Zone Speed Guidelines" Questions & Answers Will lowering the speed limit reduce speeds? NO. Studies show that there is little change in the speed pattem after the posting of a speed limit. The driver is much more influenced by the roadway conditions. Will lowering the speed limit reduce crash frequency? NO. Although lowering the speed limit is often seen as a cure-all in preventing crashes, this is not the case. Crashes are most often the result of driver inattention and driver error. However, if a posted speed limit is unrealistically low, it creates a greater speed variance (i.e. some drivers follow the speed limit while most drive the reasonable speed). This speed variance can contribute to crashes. Why do we even have speed limits? A uniform speed of vehicles in a traffic flow results in the safest operation. The posted speed limits can keep the traffic flowing smoothly provided the majority of drivers find the speed limits reasonable. To best do this, the limits must be consistent throughout the state. The speed limits also give the motorist an idea of a reasonable speed to drive in an unfamiliar location. The speed limits are used by police officials to identify excessive speeds and curb unreasonable behavior. Who Do 1 Contact? If you believe that there is a safety concern or an inappropriate speed limit posted, the person to contact depends on the type of road. TRUNK HIGHWAYS For regulatory and advisory speed limits on the trunk highway system, you may contact the district traffic engineer at your Mn/DOT district office. The trunk highway system includes: CJ Interstate Highways, o U.S. Highways and Ll Minnesota State Highways LOCAL STREETS AND HIGHWAYS For these roadways, you may contact your local road authority (county, city, or township). For advisory speed limits: The local road authority can determine these advisory speeds and post the plates without authorization from the commissioner of transportation. For regulatory speed limits: The local road authority can pass a resolution requesting an investigation by Mn/DOT. Based upon the results, Mn/DOT may then authorize the local road authority to post new speed limits. The phone numbers to call for state or local assistance can be found in the phone book under government listings. If you are unable to find the proper phone number, you may call the Mn/DOT Information Center at the following numbers: 1-800-657-3774 Greater Minnesota or 651-296-3000 Twin Cities Metro Area ..J DOUBLE FINES will be imposed for violating any regulatory speed limits in work zones or in school zones. Fines are also double for failing to reduce speed when passing by a stopped emergency vehicle with its lights flashing. ..J When an EMERGENCY VEHICLE is approaching you, move to the closest shoulder without crossing the path of the approaching emergency vehicle. You may proceed when the emergency vehicle passes you. If you are approaching a stopped emergency vehicle with its lights flashing, immediately reduce speed and, if it's safe to do so, move over in your lane away from the stopped emergency vehicle. Drivers should actually change lanes if there are two or more lanes in the same direction and there are no vehicles in their path.
