CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR ACTION CITY COUNCIL MEETING DATE: December 21 , 1993 AGENDA ITEM: Intersection Traffic Investigation - 153rd AGENDA SECTION: Street and Danbury Avenue Old Business PREPARED BY: Bud Osmundson AGENDA N� ..�� ���',� � City Engineer/Assistant Public Works Director � y� ��' ATTACHMENTS: Letter from Residents, Map, Traffic APP ED B : Literature, Memo, SEH Memo The City received a letter requesting a traffic investigation at 15 rd and Danbury Avenue and 155th and Danbury at its December 7, 1993 meeting. It is brought back to you on tonights agenda after Staff investigation. Please read the attached memo for background infarmation. A. 153rd S�reet & Danbury: The traffic warrants for the installation of a two-way stop sign are attached and the first warrant is met for 153rd and Danbury. The investigation has shown that 153rd and 152nd is a more important or main road and therefore meets Warrant #1 for stop sign installation. We have given consideration ta installation of yield signs at Danbury and 153rd. However, with the additionaf traffic which will be forthcoming after the 1994 construction season we feel it is j�stified to instali the stop sign at this time. This also would hold true for all side streets or minor streets as they intersect with 152nd/153rd Street. B. 155th Street & Danbury: The request at this intersection is for a stop sign and a playground/reduced speed sign. The traffic counts, as shown on the attached map, are in the 200-300 range on these two streets. This is somewhat higher than a normal residential street. The 155th and Danbury Avenue intersection meets the first warrant for a yield sign, which is that of right-of-way assignment. lt is recommended that a yield sign be placed at 155th Street prior to Danbury Avenue. This would assign Danbury Avenue as the through roadway. Since Danbury Avenue is adjacent to a major park, Jaycee Park, it is recommended that we do place a "Playground" sign along Danbury Avenue at or near 155th Street and another at 156th Street when that roadway is completed. Further enforcement of the speed iimit and patrolling of the area will be the best control for traffic speed. When the weather allows, tprobably spring of 1994) cross-v�ralks will be painted as appropriate at this intersection. The faflowing resolutions are recommended for the Stop and Yield sign placement which are "regulatory" signs. The Chifd At Play signs are warning wigns and do not need a resolution. RECOMMENDED ACTION: MOTION TO ADOPT A RESOLUTION ESTABLISHING STOP S1GNS ALONG 152ND AND 153RD STREETS FROM DIAMOND PATH (The Apple Valley Border) TO SHANNON PARKWAY. MOTION TO ADOPT A RESOLUTION ESTABLiSHING A YIELD SIGN ON 155TH STREET AT DANBURY AVENUE. �I COUNCIL ACTION: 4 CITY OF ROSEMOUNT DAKOTA COUNTY, MINNESOTA RESOLUTION 1993 - A RESOLUTION ESTABLISHING STOP SIGNS ALONG 152ND AND 153RD STREETS FROM DIAMOND PATH (The Appfe Valley Border) TO SHANNON PARKWAY WHEREAS, the City has received a petition from residents living within the Wensmann First through Fifth Rdditions; and WHEREAS, the City of Rosemount is concerned for safety of its residents living along and traveling streets within these Aciditions; and WHEREAS,the City Engineer of Rosemount has investigated the traffic data on these streets; and WHEREAS,the City recognizes the importance of adhering to the principles of The Minnesota Manual on Uniform Traffic Control Deuices for traffic control o� its streets, and that warrants for particular reguiatory signs, as required in the Minnesota Manual on Uniform Traffic Control Devices, must be met prior to their installation; and WHEREAS, the City Engineer has determined that 152nd Street and 153rd Street have a higher iraffic volume and is geometrically a "main" road compared to intersecting streets and is a segment of street where the application of the normal right-of-way rule is unduly hazardous; and WHEREAS,this is the first warrant listed in The Minnesota Manual of Uniform Traffic Control Devices for the installation of stop signs.

MEMO TO: Mayor McMenomy Council Members: Klassen, Staats, Willcox, Wippermann FROM: Bud Osmundson, City Engineer/Assistant Public Works Director DATE: December 17, 1993 RE: Intersection Investigation & Placement af Traffic Signs Wensmann Additions This memo serves as background or general information for you in regards to intersection investigation. The City has and should continue to cansistently follow the Minnesota Manual on Uniform Traffic Control Devices for Streets and Highways as a guide for placement of traffic signs. Without this guide the haphazard placement of signs could result, which could expose the City to liability should an accident occur that might be attributed in whole or in part to the presence of an unwarranted device. This also could expose the recommending engineer or Councif to the same liability. I will not expose myself to this liability, but Council has the authority to override my recommendations and order the placement of signs. The Police Department has determined that there has been eight accidents in this study area since 1991 . Most have been along 153rd Street with one being a personal injury accident. The basic purpose of Stop or Yield signs is to assign right-of-way at intersections. Stop signs are a substantial inconvenience to motorists and should only be used where warranted. (See SEH one page article) Stop signs are consistently requested by residents in an effort to control speeding on neighborhood streets. However, numerous studies have concluded that Stop signs have little overall effect on controlling speed. Our policy in the past has been to put "playground" or "child at play" warning signs only on Collector or main roads. We have requests for these signs during the summer months almost weekly for most neighborhood streets and could install them on every street if the Council so desires. However, the literature that has been compiled by Traffic Engineers across the United States has shown that these do very little to slow traffic after the first week or two of installation. We would have to add thousands of dollars annually to the budget to begin putting these signs on every street as requested. However, since Danbury Avenue is adjacent to a major park, Jaycee Park, it is recommended that we do place a "Playground" sign along Danbury Avenue at or near 155th Street and another at 156th Street when that roadway is completed. Further enforcement of the speed limit and patrolling of the area will be the best control for traffic speed. This Wensmann Addition area has produced a number of inquiries regarding the installation of traffic control signs since Ron became Public Works Director and myself as City Engineer. Attached is a study completed by S.E.H., Inc. in September of 1992 for the Danville-155th Street intersection. The recommendation for that intersection was to leave it as is. However, I am willing to recommend the installation of a Yield sign in anticipation of increased traffic from development to the south. We had traffic counts completed in this area this past fall which were to be used in a traffic investigation of this neighborhood in anticipation of the construction of the "connecting streets" to the south in 1994. Prior to this, no traffic counts were rtaken on these streets. Danville, Danbury, 156th Street and Darling Path all will be connected with the construction of the West Ridge 5th Addition and Shannon Pond 2nd Addition. This "connection" will change the traffic patterns in this area substantially upon their completion. Then, more analysis will be required to address the traffic problem areas. This is a normal procedure with "neighborhood" streets as compared to major collectors or highways where the right-of-way question is clear cut. � , � __--------- `� December 1, 1993 City of Rosemount Engineering Dept. 2875-145th Street West Rosemount, � � Dear Mayor McMenomy and Council Members, It has become a growing concern in our neiqhborhood the lack of proper traffic signs. We would like to have the city mark the following roadslintersec- tivns as requested so as to reduce traffic problems that now exist and to prevent any harm to the child- ren that are in the area. tTDcoDt1'ollCd iBtCr�e�oII it IS3�cd uid Dienbery: A need for yield or stop signs is needed to at least address � the right of way of traffic crossinq over 153rd. - � COtnCtol133tb Str�tan�d D�atp: A stop sign is needed alonq with a *Playqround/Reduce speed* sign. ' Danbury at this time is a dead-end to the south of 155th street so traffic traveling west to east on 155th street assumes any south bound traffic f=om Danbury will be turning which is not always the case. The corner also includes pedestrian traffic erossing over to the bike path entrance of the Jaycee Park. We would like the above intersections Iooked at i.mmed- iately and marked so as to alleviate any further traffic accidents or problems. �ttached are signatures of those � who wouZd also like to acknowledge the same coacerns . as listed above.

Intersection of a less important road with a main road where application of the normal right-of-way rule is unduly hazardous. ' 2. Street entering a through highway or street. 3. Unsignalized intersection in a signalized area. 4. Other intersections where a combination of high speed, restricted view,and serious accident record indicates a need for control by the STOP sign. Prior to the application of thes�warrants,consideration should be given to less restrictive meazures, such as the YIELD sign (2B-'� where a full • Stiop is not necessary at all times. Periodic reviews of existing installations may be desirable [o determine whether, because of changed conditions, ' the use ofless restrictive control or no control could accommodate traffic demands safely and more effectively. 2B-6 Maltiway Stop Signs The"Multiway Stop" installation is useful a>s a safety measure at some locations. It should ordinarily be used only where the voiume of traffic on the interseccing roads is approximately equal. A traffic control signal is more satisfactory for an intersection with a heavy volume of uaffic. Any of the following conditions may warrant a multiway STOP sign installation (sec. 2B-4): � 1. Where traffic signals are wananted and urgently needed, the ,�ultiway stop is an interim rneasure that can be installed quickly to control traffic while arrangemenu aze being made for the signal installation. 2. An accident problem,as indicated by five or more reported accidents of a type susceptihle of correction by a multiway stop instatlation in a 12-month period. Such accidents include right- and Ieft-turn collisions as well as right-angle collisions. 3. Minimum traffic volumes: ,(a) The totat vehicular volume.entering the intersection from all approaches must average at least 500 vehicles per hour for any 8 hours of an average day, and ; (b) The combined vehicular and pedestrian volume from the minor__ street or highway must average at least 200 units per hour for the same 8 hours,with an average delay to rninor strcet vehicular traffic of at least 30 seconds per vehicle during the rnaximum hour, but ' (c) When the 85-percentile appraach speed of the major sueei traffic ;exceeds 40 miles per hour, the minimum vehicular volume warrant is 70 'percent of the above rcquirements. 2B-7 Yield Sign (Rl-2) The YIELD sign assigns right-of-way to traffic on certain approaches to an intersection. Vehicles controlled by a YIELD sign need stop only when necessary to avoid interference with other traffic that is given the right-of- way. The YIELD sign sha11 be a downwa:d pointing, equilateral triangle having a red border band and a white interior and the v.�ord YIELD in red inside the border band. The standard size shall be 36 x 36�x 36 inches. �-� / YIELD � \ ;/ \ i � �:' 2B-8 Warrants for Yield Signs The YIELD sign may be warranted: ' 1. At the entrance to an intersection where it is necessary to assign i right-of-way and where the safe approach speed on the entrance exceeds j 10 miles per hour. . � � 2. On the entrance ramp to an expressway where an acceleration lane is i not provided. � 3. At intersections on a divided highway where the median between the yroadways is more than 30 feet wide. At such interseetions, a STOP sign �may be used at the entrance to the first roadway of the divided highway �and a YIELD sign may be placed at the entrance to the second roadway. � 4. Where there is a separate or channelized right-turn lane, without an' i adequate acceleration lane. � 5. At any intersection where a special problem exists and where an !engineering study indicates the problem to be susceptible to correction by `.use of the YIELD sign. YIELD signs generally should not be placed to control thc major flow of traffic at an intersection. However� YIELD signs may be installcd to . control a major traffic movement where a majority of drivers in that movement aze making right turns (see page 2A-1�. At such an intersection, YIELD signs should not bc erect�d on more than onc _ �approach. � YIELD signs should not be uscd on the throngh roadways of ;expressways. They may be used on an entering roadway without an adequate accelerauon lan�, but in a well-designed interchange, the sign would interfere with the free merging movement,and it should not be used under those circumstances. i� � � ENG/HEERS I pRCMITECTS I PLAHNERS 3535 VADNAIS CENTER ORNE,SL PAUL.MN 55>>0-5�08 672 4y�-QpQQ 800 325-2055 September 23, 1992 RE: ROSEMOUNT, MINNESOTA DANVILLE AVENUE AND 155TH STREET TRAFFIC CONTROL NEEDS SEH FILE N0. 92214 Mr. Ron Wasmund Public Works Director City of Rosemount P.O. Box 510 Rosemount, MN 55068-0510 Dear Ron: Earlier this year, the City requested that we review traffic control needs at two intersections; 145th Street and Shannon Parkway and 153rd Street and Danville Avenue. At a subsequent meeting with the City staff, we obtained a copy of a petition which asked for a study of the 145th Street and Shannon Parkway intersection, but also the Shannon Parkway and Dodd Boulevard intersection. We received accident data for the two intersections on Shannon Parkway but apparently there are no accidents at 155th Street and Danville Avenue. The intersection of Danville Avenue and 155th Street is a "Tee" intersection in a residentiaZ district. A short distance east of Danville Avenue, 155th Street ends at Danbury Avenue. To the west, 155th Street connects to the Apple Valley Street system and stops a few blocks west of the city limits. Danville Avenue is . only a block in length with a second Tee intersection at Dar�ee�.ing Avenue. Generally, the traffic on either street is local in nature. Because this is a e intersection, we be ieve state law requires motorists an the 'stem of the Tee" (Danvi le Avenue) to yield to traffic on 155t Street. This generall seems to occur at Tee intersections due to the need of traf ' on the stem of the Tee to slow down and tu t. Thus, the intersection generally seems to ope ate quite well without control. � Lo Af�!J -�" i�/�'� ° ��2��✓�- - N� � 5����-�N�M�� sr+oRrecuorr HENDRICKSON INC ST.CLOUD,7rfN CHIPPEWA FALLS.W! MADlSON.W! Mr. Ron Wasmund September 23, 1992 Page #2 Because Danville Avenue traffic is required to yield and is on a Tee intersection, and because the intersection is only a short distance away from another Tee intersection at Danbury Avenue, we do not believe that stop signs ox yield signs are needed or desirable. Leaving the intersection uncontrolled is consistent with many other Tee intersections within Rosemount and within this area of Dakota County. We would therefore recommend that no signs be installed at this time. Should you have any questions or need any further information, please call upon us. Sincerely, _����� Glen Van Wormer, P.E.
