1j. Feasibility Study for Utility and Roadway Improvements Frontier CITYOF .20 C HANHASSEN • 690 COULTER DRIVE • P O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 MEMORANDUM TO: Don Ashworth, City Manager _ (�-t ' _.�. York ' FROM: Gary Warren, City Engineer r T� DATE: April 5 , 1989 SUBJ: Authorize Feasibility Study for Utility and Roadway Improvements to Frontier Trail from Highland Drive to Kiowa Project No. 89-10 When Frontier Trail was first constructed around 1967 , little did ' people know that to travel on this roadway in the 1980s would be as challenging as its name implies. The roadway has been repaired and patched and sealcoated over the years; however, it has diminished to such a state that continued maintenance of this ' nature is truly a waste of money since these are only band-aid solutions and a major operation is needed for the cure. ' In 1988 , the City contracted for a "Road Rater" deflection testing of the pavement surface to determine if complete replace- ment of the roadway section and reconstruction of the sub-base ' would be necessary or if instead some sort of remedial overlay could be conducted on this roadway section. The results of the Road Rater analysis had confirmed that the sub base of the road- way has deteriorated to such an extent that complete reconstruc- tion is in order for a majority of the roadway. In addition , the storm drainage system in this area needs to be ' upgraded as well as some isolated sanitary sewer and watermain repairs which would be prudent to undertake as long as the road- way surface is being replaced. The City televised the sanitary sewer in this area in 1987 to locate these areas of rehabilita- tion . This would also be the time where we would notify the respective private utilities such as gas , telephone, cable and electric to give them an opportunity to make any necessary impro- vements to their systems and in the case of electric, to consider undergrounding of this utility similar with new subdivisions in the City. This project will be unique in that it is the first residential roadway in the City to be considered for reconstruction . This feasibility study will therefore blaze the trail in helping us to t II Don Ashworth April 5 , 1989 Page 2 establish policy as far as the funding of improvements of this nature , including any appropriate assessment policies. It has been common practice in other communities where pavement manage- ment systems are in place and street reconstruction is an annual event, to assess a portion of the reconstruction and upgrade costs to abutting property owners . The policies vary from com- munity to community but in general terms , if a roadway is being widened or curb and gutter is added when it was not in place before, the abutting residents are normally looked at to pay for the cost for the new elements of the roadway and the costs for restoring the existing portions of the roadway and utilities is borne by the community. This needs to be looked at in full detail as a part of the feasibility study and will be appropriately addressed since the cost estimates for the rehabi- litation will also be presented in the report. The City has a number of older streets in town which are can- didates for improvement and once we have established a program, the next likely candidate after Frontier Trail would be the Chan Estates area, i .e. Cheyenne road and the old town area ( see attached letter to Elinor Kerber) . It is therefore my recommen- dation that the City Council authorize the preparation of a feasibility study for utility and roadway improvements for Frontier Trail from Highland Drive to Kiowa and that it prepared by the firm of William R. Engelhardt & Associates. Attachments 1 . Location map. , 2 . Letter from A. L. Brock dated April 7 , 1988. 3 . Road Rater sheets. 4 .

Sealcoat Program: When the sealcoat program was initiated in the early 1980 ' s, it was noted that a majority of the City' s streets were in good condition and, through such a main- tenance program, we could reasonably assure that the lives of these streets could be maintained well into the future. The lower portion of Frontier Trail, Chanhassen Estates, and ' potentially Scholer ' s Addition (West 76th/Chan View/Iroquois) were specifically identified as streets not meeting City standards . By contrast, once these areas were brought up to City standards , the City would insure that the life was main- tained in those streets through continuous maintenance. It � A ' Manager ' s Comment Page 2 tis difficult to assess property owners for street costs ; however, Carver Beach, Greenwood Shores, old town section, ' West 79th Street, downtown, business park, Pleasant View, are all areas where new streets were installed either separately or in combination with utility work and the costs assessed back to property owners. All new streets, as a part of our ' Subdivision Ordinance, are required to meet current standards - curb and gutter/full depth. These owners have also paid for those streets via purchasing their lots . It was and is ' staff' s belief that it is not reasonable to have maintenance dollars pay for roadways which have been brought up to reasonable standards. ' Memorandums as considered by the City Council in establishing the seal maintenance program are proposed to be included with the feasibility study. 1 wA 1 1 `- -1 Solt=mmia,,..

' As discussed , I am greatly concerned with two problem areas. First, the curbing and run-off drain to Lotus Lake, which is located on the north side of my home. As stated, last summer the swale area was blocked by debris, and ' during the July storm turned into a raging river which came within five feet of my none. As a direct result, over $8,000 of property damage occurred, none of which was insured. I called City Hall on four occasions and was told the curbing on the east side of Frontier Trail leading to the drain would be repaired. Also, that the drain would be kept clean at all times. Instead, a crew repaired the west ' curb and I have personally cleared the drain area twice. This is a potentially dangerous situation, not only due to flooding again, but also the embankment above the drain was weakened and the ground could give way at any time. Your ' immediate attention to the curbing and drain area will be greatly appreciated. The second area of concern is the 7100, 7200 and 7300 section of Frontier Trail. The road is literally destroyed and needs to be repaired. Last week, a child ' was almost run over as a car hit one of the huge potholes and momentarily lost control. This section of Frontier Trail has been in dire need of attention for the past few years, and should be given attention before a serious accident ' occurs. Also, perhaps by repairing this section of Frontier Trail, a good portion of the drain problem will be reduced. Pieces of asphalt are constantly washed down from the 7300 block and clog the drain. ' If there is anything I can do as a property owner who pays over $5,000/year in property tax, to edpedite these matters, please contact me. ' I thank you in advance for your concern and attention. Sincerely, ���� -.•- A.L.

I I/ INTRODUCTION The City of Chanhassen contacted Braun Pavement Technologies to I conduct deflection testing on approximately 5 miles of city streets. The deflection testing was done on August 1-2 , 1988 . The testing was done with a Model 2000 Road Rater at 100 foot I intervals in both directions. The spacing was staggered in either direction so that a net spacing of 50 feet was achieved for each section of roadway. The purpose of this report is to make recommendations for pavement rehabilitation based on effective subgrade R-value, Effective Granular Equivalency, overlay thickness, and spring axle load restriction in tons per axle. This report makes reference to 2331, 2341 and Class 5. These refer to the Minnesota Department of Transportation standard specifications I for highway construction for plant mixed bituminous pavement, plant mixed bituminous surface, and aggregates for surface and base courses respectively. I I I I i I 11 I 11 I 11 I T . II FRONTIER TRAIL FROM 177 FEET WEST OF KIOWA CIRCLE II TO HIGHLAND DRIVE ANALYSIS I This section is 3188 feet long and consists of 2 .5 inches of asphalt surface. It was originally assumed that this section I consisted of 2. 0 inches of 2341 wearing course over 4 . 0 inches of 2331 binder. However, after analyzing the data, it was apparent that either the traffic reported was too low, or the in-place II thickness was not as high as originally reported. Braun Engineering Testing took 3 cores at locations indicated on the attached sheet on Frontier Trail. These cores indicate an II asphalt surface ranging from a minimum of 2-3/8 inches to a maximum of 2-3/4 inches. The data was re-evaluated using 2 .5 inches of asphalt. The traffic is assumed to be a minimum of 3 . 0 } daily ESALs. The surface condition rating is 2.3 with medium to II high severity alligator cracking located. at nearly every test point. DESIGN RECOMMENDATIONS I Area 1: 177 feet west of Kiowa Circle to Laredo Drive II R-value = 9 EGE = 8 . 0 inches Overlay = 2 .5 inches (9-ton) 1.5 inches (7-ton) 1 I Area 2 : Laredo Drive to Highland Drive R-value = 10 II EGE = 9 . 5 inches Overlay = 2 . 0 inches (9-ton) 1. 0 inches (7-ton) 1 3 II Tonnage = 7 tons per axle 1 DISCUSSION II ._ There is one area of extremely low subgrade soil strength in Area 1 located at location 349 where the effective R-value is only 4. IIf this roadway is ever reconstructed, it is recommended that the II soil be corrected at that location. 1Due to the large amount of high severity load related distress 1 (alligator cracking) , it is recommended that this section be II reconstructed. The large amount of load related distress indicates that this roadway was subject to axle loads in excess I of the 7-ton recommendation. Repeated applications of axle loads II in excess of a pavement's allowable limit will result in shortened pavement life due to accelerated fatigue. The recommended reconstruction section for this roadway is as follows: I 9-ton Design 7-ton Design f 1.5 inches 2341 wearing course 2 . 0 inches 2341 wearing course II 1.5 inches 2331 binder 5. 0 inches Class 5 Aggregate Base 5. 0 inches Class 5 Aggregate Base 1 FROM BRAUN ENS.

BOX 147 • CHANHASSEN, MINNESOTA 55317 I (612) 937-1900 April 3, 1989 II Ms. Elinor W. Kerber II400 West 76th Street Chanhassen, MN 55317 IDear Ms. Kerber: Your letter of March 22, 1989 is being forwarded to the Mayor and City Council I members so as to insure that they are aware of your concern. The staff person who will be responsible for reviewing and determining what can be done is our City Engineer Gary Warren. I will forewarn you that Mr. Warren's ability to respond quickly will be difficult. We have three engineering positions which I would normally be given the responsibility, by Mr. Warren, to work with you. Currently, all three positions are vacant and, accordingly, Mr. Warren is carrying out the responsibilities of four people. I am also fearful as to the I conclusions that Mr. Warren will probably reach. I am guessing that your street is over 30 years old. During most of the life of the street, the City did not have a street sealcoat program in effect. During the past 10 years, the II street department, on at least two different occasions, attempted to restore the street via patching/sealcoating. Those programs have not worked. Most of the street has major alligator sections typical of eroded base material. Similarly, there is no curbing to control and direct runoff. What asphalt curbing origi- ' pally existed is virtually non-existent. I am sure these conditions have contributed to the undermining of the base material. II The above comments were made solely based on 20 years of seeing various street conditions and to forewarn you as to probable conclusions. Today engineering equipment exists to determine whether streets can be salvaged and what actions II will be required to do such. Again, Mr. Warren will attempt to get to your problem as soon as possible. Thank you for your consideration. II Sincerely II Don Ashworth City Manager IIcc: Mayor and City Council Gary Warren, City Engineer II 1 27 /Z 4,2, iyf9, . 1 cef4 e_e-e-t44..e. ,1/2e--1 .-J I m 7 6—. —a/ I M - GZ27t..--e-il-,----- 2,.,e,'-e-C-1,ta,i...,z-Va-e_z) z-..e..)-a-- --4.1 - AAA} 7)74i, -/-).4.-/e/i-e) .-f-td ce-ed-4 e-ii , , 4 0 a-Le.). -9-z--0-0-e-L, ,i_.; e,L6-4A/ .--4,-7-z. cz,t- x7i0 a z,u, 7 6i- s. rAL..e."1--- I ,,,;,,, (9,,,e, / 7 ii7i, a)_& -/1_,,,,,,� ' .u4-- Al -1%u> _.
