To enable the City to identify improvements that will provide for an efficient level of service and life -cycle cost, staff inspects and rates its pavements on a regular basis. The City also has developed a pavement improvement plan based on resurfacing pavement and base treatment with intermittent sealcoating. The goal is to provide maintenance improvements at scheduled intervals. For example: Activity Initial Construction Sealcoating Sealcoating Resurfacing Sealcoating Sealcoating Reconstruction Schedule Year 0 Year 8 Year 16 Year 24 Year 32 Year 40 Year 48 This is an ideal and aggressive sequence for street maintenance. Note that the final reconstruction may be substituted with resurfacing activities if roadway base is in good condition, with the intent to extend road life for an additional cycle of 24 years. Due to the variability with budgets, road configurations, traffic patterns, condition of utilities, source of funds, other projects, etc., the basic schedule above varies and fluctuates for each roadway segment. As part of identifying the best candidate for this year's pavement resurfacing project, City of Fridley Engineering Division staff works with Street Maintenance Division staff to develop the list of candidate projects. The factors considered are physical characteristics, budgetary factors, and other considerations are listed to assist in selection of a best candidate. The Engineering Division monitors existing pavements through semi-annual inspections. From this inspection information, the Engineering Division prepares a Street Resurfacing Plan consistent with the Street Capital Improvement Plan, which designates candidate street segments for construction, reconstruction, and rehabilitation. The City of Fridley also performs preventative surface maintenance (e.g. sealcoating), routine crack sealing and pothole patching maintenance. The amount of street maintenance on this segment is increasing annually due to the rapid deterioration of the existing pavements. The Engineering Division has prepared a Street Resurfacing Plan consistent with the Long -Term Street Maintenance Program, which designates candidate street segments for construction, reconstruction, and rehabilitation. The Plan identifies the areas within the city and the anticipated year for maintenance projects. Please refer to the following map summarizing the Long -Term Street Maintenance Program. Resolution No. 2018 - 10 STREET RESURFACING PLAN Page 6 Resolution No. 2018 - 10 : A • Page 7 The area is a mix between residential, commercial and higher density residential property. The area also includes Medtronic Rice Creek East and Creek View Park. The neighborhood is generally bordered by Stinson Blvd to the east, Central Avenue to the west, Medtronic Rice Creek East to the north and Rice Creek to the south. Street segments selected for rehabilitation include: Street and utility improvements, including bituminous asphalt overlay, pavement reclamation, drainage, water main, and utility repairs including the street segments as follows: 69th Avenue NE Central Avenue NE to Stinson Blvd NE Anoka Street NE 69th Avenue NE to South Terminus See Figure A in the Appendix for a map of proposed street construction. The street segments were built in 1968. Some resurfacing and widening occurred on this street segment in 1981. Street resurfacing also occurred in 1995 and seal coat was placed in 2001 and 2006. Currently, the streets provide 2 -way traffic with no shoulder striping. It is estimated that the average daily traffic ranges from around 2800 vehicles per day based on observation and historical data of similar streets. The record pavement thickness ranges from 3.25 inches to 4.5 inches. The underlying aggregate base thickness ranges from 0" to 5" of Class 5 base. The street widths are 54 feet and 64 feet for 69th Ave, and Anoka Street has a width of 23 feet. PROPOSEDIMPROVEMENTS Overview The street rehabilitation project compliments and combines improvements including a "road diet", an off-street shared use trail, added storm water quality benefits with a storm water swale and roadway resurfacing. Resurfacing the streets is the main goal of the project; however, maintaining the existing roadway width of 69th Avenue is quite expensive and time consuming due to its excess width. 69th Avenue is currently 54' wide where it does not have turn lanes, and could be reduced by nearly half in different configurations, which would in turn reduce maintenance of pavement surfacing and snow removal and ice control. The street rehabilitation project was submitted for eligible Rice Creek Watershed District's 2018 Urban Stormwater Remediation Cost -Share (USWR) Program with a concept that would reduce impervious surface and reduce nutrient loading, suspended solids and chlorides to the nearby receiving water, Rice Creek. The 69th Avenue Road Diet and Infiltration project and was approved for a grant of $47,500 in funding by the RCWD. Resolution No. 2018 - 10 Page 8 Street rehabilitation is funded through the typical combination of funding sources, including Minnesota State Aid System (MSAS) funding and special assessments. Due to the proposed reduction in width of the street, special assessments for the street rehabilitation will be reduced. Staff held an open house on February 13, 2018 and met with Medtronic, Rice Creek Townhomes and Timber Ridge Townhomes to discuss the proposed street project. Staff presented different design options for changing of roadway geometrics. Staff answered questions and received feedback about the design options presented. Staff analyzed the options and redesigned the design based off comments and concerns received at the meetings. Elimination of parking, medians blocking access and access during construction was the main concerns that were brought to our attention at these meetings. Timber Ridge townhomes had a major concern with loss of parking. At a followup HOA meeting, staff responded with an option that would provide Timber Ridge with an extra 12 parking spaces on Anoka Street at the cost of Timber Ridge, but they have subsequently declined because they didn't know how they would patrol from Rice Creek Townhomes parking their spaces. Staff has also had similar outreach meetings with Medtronic and Rice Creek Townhomes, who are generally supportive of the project. The length of all segments included in this residential project area is approximately 0.65 miles. The work will include pavement resurfacing, water main replacement, and drainage improvements. In February 2018, a resolution was adopted by City Council to initiate the 2018 Street Rehabilitation Project No. ST2018-01. Geometric Revisions 69th Avenue will be reduced in roadway width, and parking eliminated on both sides of the roadway. This is to accommodate a proposed off-street trail and storm water swale on the south side to avoid encroaching into resident and the townhomes yards. The elimination of parking will also provide for better sight lines along 69th Avenue as parked vehicles can currently obscure vehicles traveling on 69th Avenue. The reduced road width will help with less maintenance (pavement repairs, plowing, deicing salt), reduce the quantity and improve the quality of stormwater runoff, reduce roadway speeds and improve traffic safety, provide opportunities to pedestrian/bicycle users, and improve the aesthetics of the roadway. Feedback from public meetings indicated the desire to shift the road section to the north rather than the south. While this was the reverse of our initial concept in order to maintain the existing trail in its current location, the existing trail would better serve the neighborhood by relocation to the south side of the road. With the condition of the trail and associated retaining wall requiring reconstruction, and the fact that the trail does not meet current standards, a relocation of the trail to the south would provide a net benefit with little additional cost. Resolution No. 2018 - 10 Page 9 The water quality improvements were also located to the south of the proposed roadway, as concerns regarding restricted access with a median and higher costs of median construction outweighed the potential speed reduction benefit in the assessment of staff and adjacent owners. The Rice Creek Watershed District has advised that they are in agreement with this modification. Pavement Resurfacing Rehabilitation of the streets will include asphalt reclaiming, asphalt paving, concrete curb repairs, and miscellaneous utility repairs. Damaged or settled concrete curbs will be replaced. Construction records indicate that some streets were found to have an adequate combination of aggregate base and asphalt and others found to have insufficient aggregate base and/or asphalt. Soils in the area are generally granular and provide for a stable sub -base. Geotechnical soil exploration is being performed to verify existing conditions and identify any soil correction needed. Staff recommends standard local roadway pavement and base rehabilitation consisting of full depth reclamation and topped with Y-3.5" of asphalt pavement. Water Main Improvements Existing valves within the project area will either be replaced, or repaired, and fire hydrants will be replaced with the project. The Engineering staff will consider allowing various material and installation options to minimize costs and disruption. Sanitary Sewer and Storm Sewer Repairs Sanitary sewer repairs will not be a part of the 2018 project. No defects were identified with the sanitary sewer system in this project area. Castings on the sanitary sewer manholes will be either replaced or reset as a part of the paving. Staff will provide inspection service on resident laterals to identify severe root intrusion at the main connection. Property owners have been notified and may coordinate with the Sewer Division to complete a video inspection of the service line. Excavations to repair and clean service laterals with severe root intrusions are born by the property owner, per City Code. Storm sewer repairs will include manhole and inlet adjustments and repairs. Catch basin structures are generally in good condition, but structures in the project area have been identified as requiring repair, and this work will be included in the project. Stormwater Quality Improvements The street rehabilitation proposed "Road Diet" will allow for space to add a storm water swale along the south side of 69th Avenue. This would reduce the quantity and improve the quality of stormwater runoff. The cost -share grant with Rice Creek Watershed District will help pay for these improvements. Residents in the area have been informed of the City's Raingarden program, and several have indicated interest. We will continue to work with residents, and install raingardens where appropriate, and beneficial. Resolution No. 2018 - 10 Page 10 Private Utility Work The project scope has been provided to private utilities to allow them to upgrade their facilities during the project. At this time, CenterPoint Energy has identified a minor improvement that they may want to do. Other private utilities have not provided information on their need to upgrade or repair their facilities. ESTIMATED COSTS The project cost is estimated to be $740,700. These estimates include 10% contingency and overhead costs relating to technical services, printing, publishing, permit fees, etc. All costs are preliminary, but are expected to stay within the budgeted amount. Estimated costs of the project can be found on Figure B of the Appendix. FUNDING SOURCES Costs for this project will be paid using Minnesota State Aid System funding, utility enterprise funds, and special assessments. The street rehabilitation work is subject to special assessment; utility work is not proposed to be subject to special assessment. A preliminary project budget can be found in Figure C of the Appendix. Street Rehabilitation Funding The estimated cost of $601,000 for the City's street and stormwater quality will be funded using monies from special assessments and the City's Minnesota State Aid System account ($304,400), and supplemental funding from the Rice Creek Watershed District ($47,500) and City's budgeted match of $70,000 from the Stormwater Fund. The City will assess adjacent residential properties in accordance with its major street maintenance policy for local streets. These assessments will provide approximately $179,100 based on the full project scope. The following assessments are based on past history as applied by Council policies for Low Density Residential (single family, duplex). Using these past methods of calculating assessments, and considering our preliminary project budget, staff has estimated assessment of approximately $2,350 per unit for Low Density Residential properties. The remaining balance of approximately $304,400 for local street resurfacing will be reimbursed from the City's Minnesota State Aid System account. Water Main Improvements The estimated cost of $94,200 for upgrading the water main distribution system will be funded using monies from the Water Utility Fund. In 2018, $150,000 in funding is identified with in the CIP as a capital expenditure. Sanitary Sewer and Storm Sewer Repairs Utility funding will be applied to repairs to the Sanitary Sewer and Storm Sewer collection systems. General repairs are expected to be $115,500, both within budget. Resolution No. 2018 - 10 SUMMARY Page 11 The work proposed for ST2018-01 Street Rehabilitation project is consistent with the City of Fridley's Long -Term Street Maintenance Program, 2018-2022 Capital Investment Program, and can be fully funded by its 2018 Budget. The project is cost effective, necessary, and feasible from an engineering standpoint as described in this report. The Engineering Department recommends that the City Council approve this project as presented.
