Hansen FEASIBILITY REPORT FOR ZONE 7 STREET DATE: 113 � DA T REHABILITATION AND ORDERING THE PUBLIC IMPROVEMENT HEARING, CITY PROJECT NO. 1202 Background: Staff has developed preliminary plans and prepared the Feasibility Report for Zone 7 of the Annual Street Rehabilitation Program. West of TH 47, Zone 7 is bounded by California/Main Street on the west, University Avenue (TH 47) on the east, 45 Avenue on the north, and 37 Avenue on the south; East of TH 47, Zone 7 is bounded by University Avenue (TH 47) on the west, Central Avenue (TH 65) on the east, 40 Avenue on the north and 37 Avenue on the south. In addition, 4 Street from 40 Avenue to 42n Avenue was added to Zone 7. Previously, Zone 6 was divided into 2 project years due to the scope of the reconstruction work. Analysis /Conclusions: Attached is the Feasibility Report that details the scope of work for Street Rehabilitation in Zone 7. Particular issues are summarized below: 1. Rehabilitation Strategies: Three treatment strategies are utilized in the street rehabilitation program: mill and overlay, partial reconstruction, and full reconstruction. In Zone 7, full reconstruction and mill and overlay is proposed for the streets identified on the attached area map. A fourth strategy, seal coating, is addressed under separate engineering reports when seal coating work is proposed. Staff utilizes three methods in evaluating the condition of the street and determining appropriate treatment: 1. Present physical structure (cross- section): Each street within Zone 7 has been excavated down to their sub -base material and the individual street segment cross - sections are catalogued. 2. Non - destructive strength determination and condition rating: Braun Intertec, a geo- technical engineering consultant, conducted tests on all streets at 50 -foot intervals with a dropping weight deflection test. From this, the strength of the road segment is determined. Braun also develops their own pavement conditions index. 3. Overall Condition Index (OCI): Staff also reviews each street segment by measuring the type and quantity of each type of cracking in the pavement. This information along with other factors such as drainage and physical structure is used to determine an "overall condition index ". An OCI of 70 or greater suggests seal coat is the appropriate treatment. An OCI between 69 and 55 reflects that the COUNCIL ACTION: CITY COUNCIL LETTER Meeting of: 11/14/11 AGENDA SECTION: WORK SESSION (A) ORIGINATING DEPARTMENT: CITY MANAGER PUBLIC WORKS ITEM: RESOLUTION 2011 -xx ACCEPTING THE BY: K. Hansen BY: FEASIBILITY REPORT FOR ZONE 7 STREET DATE: 11/9/ 11 DATE: REHABILITATION AND ORDERING THE PUBLIC IMPROVEMENT HEARING, CITY PROJECT NO. 1202 Continued — Page 2 bituminous pavement is showing signs of significant deterioration and a mill and overlay is required to strengthen the pavement. An OCI of less than 55 suggests the best course of action is to reconstruct the street, typically because both the pavement and the base under the pavement are failing. The need for full or partial reconstruction depends on the condition of the curb and gutter. The results are then used to determine the appropriate treatment to maximize the life of the street. 2. Utilities Replacement: Utilities have been reviewed in Zone 7. Staff utilized structure inspections, televising, history of water main breaks, age of water main and services, leakage testing (independent testing), and previous engineering reports in determining utility recommendations. Only minor water main and sanitary sewer utility work is proposed. Undersized storm sewer pipe and structure replacements /repairs are also proposed. 3. Assessment Methodology: Street Rehabilitation in Phase 1, Zones 1, 2 and 3 all followed the previous assessment policies for each area. Under the 1999 Alley Construction Program and in subsequent Zones, a "unit" assessment methodology was employed rather than using a "front foot" rate basis. The area of Columbia Heights west of Central Avenue is essentially a block type development pattern with streets and avenues. The existing assessment policy for this area would involve "street" assessments and "avenue" assessments. The "street" frontage (typical front of property or where driveway access is) would pay a particular rate for the full frontage for that type of treatment (mill and overlay or full reconstruction, for example) used on that street. That same parcel would pay a reduced rate for the avenue for the full frontage. 4. Scope of Work: Streets that were rehabbed in 2004 and 2006 would receive a seal coat at no cost to the property owner following the Program Policy. The cost sharing policy provides a 50/50 cost share for full reconstruction streets, and 85/15 for mill and overlay.

Zone 7 was amended in 2010 to include 4th Street from 40 Avenue to 42 Avenue. IMPROVEMENTS: Full Street Reconstruction — Concrete curb and gutter, granular sub -base if needed, new aggregate base and new bituminous surfacing. Mill and Overlay - Random curb and gutter replacement as required, and new 2" bituminous surface. Utility Construction — Water main replacement /repairs as required to maintain the distribution system. Sanitary sewer replacements /repairs as required to maintain the collection system. Storm sewer replacements /repairs as required to improve or maintain the collection system. INITIATION: City Council in accordance with the Street Rehabilitation Policy. OWNERS Full Reconstruction ABUTTING 1. 4 Street, 40 Avenue to 42 Avenue (39) OR IMPACTED: Mill and Overlay 1. 3 Street, 42 Avenue to 44 Avenue (33) 2. Summit Street, 5 Street to 40 Avenue (18) ISSUES: The following is a study of the key project issues. Street Reconstruction The proposed roadway would consist of a two lane bituminous cross section with 2 concrete curb and gutter. The roadway width would generally match the existing street width. Mill and Overlay The proposed construction would consist of milling off 1" of bituminous pavement across the entire street surface and paving a new 1 /4 (gutter) to 2" (centerline) bituminous mat. Existing concrete curb and gutter would be preserved except for sections with poor drainage. Driveway openings with drive - over curbs will be removed and replaced on a lineal foot cost at the request of property owners. Utilities No major water main, sanitary sewer or storm sewer replacement is proposed in Zone 7. For the storm sewer system, staff is proposing to replace undersized pipe and structure replacement /repair where existing structures are deteriorated. Roadway construction will include minor modifications to existing water main, sanitary and storm sewer utility surface structures in order to meet proposed finish grades. Sidewalk City staff recommends hazardous sidewalk within all of Zone 7 be replaced as part of the project. The criteria for hazardous sidewalk is defined in the City's policy. The cost is approximately $8,360, spread over 40 properties. The cost per single family property ranges from $100 to $600. The majority of the sidewalk replacement is not adjacent to streets included in the 2012 Street Rehabilitation program. Staff recommends the cost for hazardous sidewalk replacement be absorbed by the Infrastructure fund. FEASIBILITY: The proposed improvement project is necessary to provide consistency with the street rehabilitation policy, cost - effective with the inclusion of partial city funding, and technically feasible as prescribed in the construction recommendations found elsewhere in this report. The project and project elements should be implemented as proposed in this study. The improvements, once completed, will provide a benefit to the properties served. SCHEDULE: Construction is scheduled to begin in late spring of 2012, with substantial completion occurring in the summer of 2012. Council receives Feasibility Report and orders Public Improvement Hearing Nov 14, 2011 Public Informational meeting prior to Public Improvement Hearing Jan 5, 2012 Public Improvement Hearing and Council orders Public Improvement Project Jan 17, 2012 or Jan 30, 2012 Council Approves Plans and Specifications, Authorizes Advertisement for Bids Feb 13, 2012 Bid Opening Mar 6, 2012 Council Awards Contract Mar 12, 2012 Begin Construction May 14, 2012 Construction Completed June 29, 2012 3 FINANCING: Financing would be a combination of assessments to benefitted properties, infrastructure fund including Municipal State Aid funds (population apportionment), and utility funds. The estimated construction costs for each option are as follows: Type of Construction Proposed Assessments Infrastructure Fund Full Reconstruction $ 165,500. $ 117,000. Mill and Overlay $ 110,300. $ 8,900. Engineering and Administration $ 36,500. The assessments reflect a flat fee of 10% of the construction cost included in the amount to assess for a portion of the Engineering and Administration costs. Percentages proposed to be assessed for street rehabilitation are consistent with the policy followed under each of the prior street rehabilitation zones. Utility work performed as part of the Zone 7 project will be paid for from the appropriate utility fund. Proposed sidewalk repair is not included in the infrastructure fund amount shown above. ASSESSMENT: Assessments will be in accordance with the City's Street Rehabilitation Ordinance and past practice. Assessments can be based on a per foot basis or a parcel basis. Following the other Zones assessment policies, assessments would be on a Street and Avenue parcel basis. A Street assessment would be at the developed rate for the particular rehab strategy while Avenue assessments would be at approximately 1/3 of the street rate extending 1 /2 block in either direction of the Avenue. This assumes that all parcels benefit equally for the strategy in front of their property or abutting it, in the case of the Avenue. 4 2012 IMPROVEMENT PROGRAM COLUMBIA HEIGHTS, MINNESOTA ESTIMATED ASSESSMENTS - PROJECT NO. 1202 ZONE 7 STREET REHABILITATION PROGRAM (Section 35, T30N, R24W) I.

This program was set up to preserve the large investment in and extend the life of the local street system. Under the Street Rehabilitation Program, the City is divided into seven zones (or areas) providing for a repeating 8 -year program, with the additional year added for alleys or other projects. Analysis /Conclusions: At the time that the original program was set up, a 20 -year cash flow projection was prepared by Public Works. At that time, a detailed analysis of the condition of the City streets was not available. Therefore, assumptions were made based on the age of the street section and the likely treatment to extend that section life. Many streets were assumed to be in satisfactory condition, with the recommended treatment of a mill and overlay. As the program moved into and progressed through the construction phase, detailed analysis became available each year. Staff provided the City Council with updates of the 20 -year cash flow in 2002 (1 /7/02), 2005 (1/17/05), and 2007 (7/16/07). By completing Zone 7 in 2012, the City will have completed two 8 -year cycles of the Rehabilitation Program. A couple of important program assumptions should be noted: • The City pays for the first seal coat after one of the three rehabilitation treatments. • In the first two cycles, a couple of the zones have been split into quadrants, adding additional years to the overall program. • The assessment policy and associated City share (percentage) remains constant over the program. • State Aid, alley, or other construction is assumed in each subsequent "off' year at $170,000 (unfactored). • Additional program revenue of $270,000 to $300,000 annually is included from the certification of the City's Local State - Aid System, which must be recertified every two years and is not guaranteed. • The program recognizes that infrastructure represents a huge public investment and in the long term, it is more cost - effective to make an investment to maintain streets at a satisfactory or good condition level as opposed to letting the streets go and bear a more extraordinary cost in the future. One of the primary funding sources that the City uses annually is our State -Aid system. In recent years we have been using the maximum amount under the funding rules. This, combined with other State -Aid work, has drawn our account to a zero balance. In 2012 and 2013, . MnDOT has indicated that they will be replacing the signal systems at five or six intersections on Central and University Avenues. By Agreement, the City cost shares based on the local streets (or legs) at each signal system. The estimated Local costs will be in the range of $585,000 to $765,000, depending on if MnDOT does five or six intersections. Additionally, major work on our State -Aid system has not been conducted since the early 90's. Several segment lengths are in need of having rehabilitation work performed. Recommended Motion: To sustain the viability of the program, staff is recommending completing Zone 7 in 2012, suspending the program in the years 2013 and 2014, and continuing in 2015 with Zone 1. This will allow our State Aid fund to pay for anticipated signal work in 2012 and 2013; and for rehabilitation and other improvements of several State Aid streets to maintain our certification COUNCIL ACTION: c CD E a, 0 as a aJ fa N C CO � o a L > CU Q as +a as 9 a) U '0 4— 0 dO a) c to L s 1._ N u A cu cc U o O O 0 O 0 0 C11 0i -p O 1 1 O 1 1 1 1 i i i 1 0 'CI' Cr Cr M of co Q u N O 0—...
