C.b, CITY OF SHAKOPEE Memorandum TO: Mayor & City Council Mark McNeill, City Administrator FROM: Bruce Loney, Public Works Director SUBJECT: Ordering Feasibility Report for 2007 Street Reconstruction Project DATE: October 3, 2006 INTRODUCTION: Attached is Resolution No. 6510, which orders the feasibility report to be prepared for the following streets: . Main Street, 6th A venue to 10th Avenue . ih A venue, Spencer Street to Market Street . 6th A venue, Spencer Street to Main Street . 8th Avenue, Spencer Street to Market Street . Dakota Street, 3rd A venue to Milwaukee Road BACKGROUND: Staffhas completed the review of the proposed 2007-2011 Capital Improvement Program which includes street preservation projects on the streets listed above. The above streets have deteriorated and are candidates for reconstruction. Attached is a map showing the proposed study area for the 2007 Street Reconstruction Project. In the feasibility report, staff will investigate street reconstruction along with utility replacement. In order to reconstruct these streets during the summer months of the 2007 construction season, the feasibility report should be authorized at this time. ISSUES: With street reconstruction projects, there have been two issues that are unresolved with Shakopee Public Utilities Commission (SPUC) and are as follows: 1. Assessments for water service lines. 2. Replacement Policy ofwatermain in street reconstructions. On the first issue, SPUC has discussed the option of assessing water service lines to the customer similar to the City assessing for sanitary sewer lines. SPUC also has stated their desire is to be consistent with the City's service lines. City staff has reviewed our Assessment Policy over the past year and is recommending that the service lines, if replaced in a street and utility reconstruct project, would not be assessed. The real "benefit" from a reconstruction project is the street according to appraisers. Staff would also recommend that the City consider increasing the percentage of street reconstruction assessment to 30% and also consider a maximum assessment per lot due to difficulties in proving benefit. On Issue No.2, SPUC's staff has been working on a policy for when watermain should be considered for replacement. Current SPUC policy to date, is that much of the watermain in the 2007 proposed reconstruction area would not be replaced. City staff has reviewed the sanitary sewer television tapes and has. determined which blocks of sewer should be replaced. Staff does not believe the sewer main and services can be replaced effectively with a "live" watermain in place. The difficulty is that the watermain is a certain age cast iron pipe and removing the soil support will damage the pipe. Also, this type of construction will add cost to the sanitary sewer reconstruction. In order to do this project effectively, the watermain should be replaced with the sewer main. If the watermain is not replaced, staff s opinion is that the proj ect should not go forward as it is not practical to reconstruct the street section without replacing deficient utilities. This issue may take a joint SPUC/City Council meeting to resolve. City staff has been working with SPUC's staff to get a replacement policy for watermain that would coincide with City sewer main replacement so both utilities are on the same timeline. SPUC's staffwill be bringing this issue to the Commission at its next meeting. Staff would need direction from City Council on the assessment issue and utility replacement on a street reconstruction project as part of preparing the feasibility report. ALTERNATIVES: L Adopt Resolution No. 6510. 2. Deny Resolution No. 6510. 3. Authorize the appropriate City official to execute an extension agreement with WSB & Associates, Inc. 4. Do not authorize the appropriate City officials to execute an extension agreement with WSB & Associates, Inc. 5. Provide staff direction on assessment questions for street reconstruction projects and on SPUC watermain replacement policy. 6. Table for additional information. RECOMMENDATION: Staff recommends Alternative No.1, so that the proposed street reconstruction project feasibility study can be initiated for possible construction. ACTION REQUESTED: 1. Offer Resolution No. 6510, A Resolution Ordering a Feasibility Report for the 2007 Street Reconstruction Project and move its adoption. 2. Authorize the appropriate City official to execute an extension agreement with WSB & Associates, Inc. 3. Provide staff direction on assessment questions for street reconstruction proj ects and on SPUC watermain replacement policy. en~ Public Works Director BUpmp ENGRl2007PROJECT/2007RECONSTRUCTIONIWORDlMEM6510 RESOLUTION NO. 6510 A Resolution Ordering The Preparation Of A Report On An Improvement To The 2007 Street Reconstruction Project WHEREAS, it is proposed to improve Main Street, from 6th Avenue to 10th Avenue; ih A venue, from Spencer Street to Market Street; 6th A venue, from Spencer Street to Main Street; 8th Avenue, Spencer Street to Market Street; and Dakota Street, from 3rd Avenue to Milwaukee Road by reconstruction of sanitary sewer, watermain, storm sewer, concrete curb & gutter, aggregate, bituminous paving and all appurtenant work and to assess the benefitted property for all or a portion ofthe cost ofthe improvement, pursuant to Minnesota Statutes, Chapter 429.

This proposal letter presents our planned scope of work and the associated fees for this project. The purpose of our work would be to obtain information regarding subsurface conditions, which can be used to develop geotechnical engineering and construction recommendations. We have reviewed the map and drove the site to acquaint ourselves to the proposed construction area. Your request for proposal states that eight (8) ten-foot borings will be taken. As discussed by phone your personnel will locate the holes in the field and we will coordinate the actual boring locations with the survey crew that will be obtaining the topographic information. We will obtain soil specimens from borings by standard penetration method, make detailed field boring logs noting condition and thickness of any existing pavement, and make proper laboratory tests, analyses and evaluations to base our recommendations for pavement sub-grade and pavement structure design and construction. Where borings exhibit non-uniform sub-grade character, additional borings may be recommended to define this non-uniformity. The result of our field exploration program, along with boring logs and a boring location diagram N would be represented in a final geotechnical report. Our engineering analysis and recommendations would also be presented in our final report. The fees for our field exploration and engineering analysis are presented in the foUowingtable: ;;';" / ,4' Item Quantity Units Unit Cost Extended Total Mobilization 1 L.S. $ 300 $300.00 SPT Borinas (10' deep) 8 each $ 160 $1280.00 Soil Gradation 5 each $100 $500.00 LL & PI (Atterberg limits) 3 each $ 75 $225.00 Asphalt repair 8 holes 8 each $ 30 $240.00 Enaineerina Report 1 L.S. $600 $600.00 Estimated Total Project Cost $3145.00 If poor soils are encountered at the proposed drill sites and depths, additional bores or deeper sampling may be required to develop engineering recommendations. Additional bores or deeper sampling would be completed at a rate of $16 per foot. If deeper sampling and/or additional borings are recommended, we will notify you and obtain your authorization, prior to proceeding with this work. The cost for our services would not exceed the estimated total cost given herein, unless unanticipated conditions are encountered and your authorization is obtained.
