I. INTRODUCTION
The City of Woodbury is planning to reconstruct Upper Afton Road, from Century Avenue to Weir Drive, during the 2019 construction season in accordance with its Capital Improvement Plan. The general location of the proposed project within the City is shown on attached Figure 1 in Appendix A. Upper Afton Road is designated as a municipal state aid (MSA) route and therefore would be improved per State Aid standards. The Pavement Condition Index (PCI) of the street ranges from 16 to 66, with an average overall PCI of 38. Pothole repairs and thin overlays have been performed to keep the roads in a drivable and relatively smooth condition. A significant amount of street maintenance funds are used in these areas. Two separate neighborhood meetings were held with the adjacent property owners on August 29 and October 4, 2018. The proposed project scope, costs, and funding sources were discussed at these meetings. Property owners had an opportunity to comment on the project and ask questions. Overall, those in attendance recognized the need for pavement rehabilitation; however, there were some comments in opposition related to assessment cost estimates. Additional neighborhood meetings will be held during the design process to allow for additional input from the property owners and prior to the start of construction. This report includes a discussion of the improvements required for this street rehabilitation project. It also provides preliminary cost estimates for the proposed improvements and identifies funding sources to finance the work.
II. REQUIRED IMPROVEMENTS SANITARY SEWER
There is an existing 9-inch diameter vitrified clay pipe (VCP) sanitary sewer within the southerly boulevard, from Century Avenue to just east of the Woodbury Middle School property. This pipe was installed in 1960. An additional 8-inch diameter VCP sanitary sewer was constructed in 1984, from Hillcrest Drive to Weir Drive, as part of the Woodbury Square Water and Sewer Extensions project. Based on the televising that was done this summer, it is proposed to remove and replace the 9-inch VCP with 8-inch polyvinyl chloride (PVC) pipe, from Century Avenue to Esther Lane, due to the amount of sags and cracks with these pipe runs. The remaining pipe is generally in good condition. There are a few leaking joints and one cracked pipe that will be rehabilitated with inline repairs. The manhole structures are also in good condition. There are four structures that have over 15 inches of adjusting rings. A 12-inch high barrel section will be added to these structures to reduce the amount of adjusting rings needed. The sanitary sewer manhole castings will be salvaged and reinstalled, and the existing concrete adjusting rings will be replaced with new high-density polyethylene (HDPE) adjusting rings to conform to current City standards.

WATER MAIN
The existing water main that serves the properties along Upper Afton Road consists mostly of 6-inch and 12-inch diameter cast iron pipe (CIP). Some of the pipe was installed as early as 1956, with the majority being over 50 years old. It is proposed to remove all of the existing CIP water main and replace with new ductile iron pipe (DIP) mains. The City has a history of breaks and poor condition with cast iron pipes and has an initiative to replace it to reduce costly emergency repairs and interruption to service.
HOUSE SERVICES In the area where the sanitary sewer is being remove and replaced (i.e. between Century Avenue and Esther Lane), all houses that are currently served off of Upper Afton Road will receive a new 4-inch diameter PVC sanitary service and a 1-inch diameter copper water service, from the main in the street to the right-of-way (ROW) line. At the ROW line, the new sanitary sewer pipe will be connected to the existing service pipe from the house. Also, a curb stop and box will be installed at the ROW line and will be reconnected to the existing water service from the house. A right of entry will be needed from each residence in order to perform this work, as a portion of it will be outside of the ROW.
STORM SEWER The majority of the storm sewer within Upper Afton Road is reinforced concrete pipe (RCP) that was installed in 1990 as part of the Upper Afton Road MSA 192-110-02 project. There is some older RCP storm sewer within the southerly boulevard, between Alderwood Drive and Oakwood Road, which was installed in the late 1960’s and early 1970’s. Based on televising performed this summer, all storm sewer is in relatively good condition. However, there are three pipe sections with minor cracks that will be rehabilitated with inline repairs. In addition, approximately 900 feet of the existing storm sewer will be removed and replaced with new RCP pipe due to the proposed water main and sanitary sewer replacements. The storm sewer manhole castings that are in good condition will be salvaged and reinstalled. Existing concrete adjusting rings will be replaced with new high-density polyethylene (HDPE) adjusting rings to conform to current City standards.
STORM WATER QUALITY IMPROVEMENTS Upper Afton Road is within the Ramsey-Washington Metro Watershed District. Because this is a linear project that disturbs more than 1 acre of impervious surfaces, this project will be required to treat 1.1 inches via infiltration off of all new and reconstructed impervious surfaces. As part of the design process, the Upper Afton Road corridor will be evaluated for opportunities to provide the infiltration required. If opportunities aren’t present, other options include construction of offsite BMPs, use of banked volume reduction credits, or payment into the Stormwater Impact Fund. It should be noted that there is a cost cap for volume reduction set at $30,000 per acre of impervious. This report includes costs for the watershed requirements, along with costs to retrofit three existing storm manholes with sump structures.

STREETS Upper Afton Road is a 2-lane, urban roadway and is classified as a collector road in the 2030 Transportation Plan. It was reconstructed in 1990 as part of the Upper Afton Road MSA 192-110-02 project. It is currently 36 feet wide (face of curb to face of curb) from Century Avenue to Tamarack Road and 32 feet wide from Tamarack Road to Weir Drive, where it widens for a right turn lane at Weir Drive. A traffic study was recently completed to determine the proper lane configuration of Upper Afton Road based on anticipated future traffic volume generated by development of the large, unplatted parcels (Jordan property) east of Upper Afton Road, near Tamarack Road. A copy of the traffic study is attached in Appendix D. The study recommends widening the segment north of Tamarack Road to a 3-lane roadway to accommodate the projected 2040 traffic volume of 10,000 vehicles per day. The width of the existing right-of-way along Upper Afton Road, north of Tamarack Road, ranges from 66 feet to 73 feet. The proposed 3-lane configuration would consist of two 13-foot wide (to face of curb) thru lanes and a 12-foot wide continuous center left turn lane, for a total width of 38 feet, from face of curb to face of curb. This segment of Upper Afton Road would need to be widened two feet (one foot on each side) to accommodate the 3-lane configuration, which would still fit within the existing right-of-way. The road would be tapered back to the existing width of 32 feet south of Tamarack Road. However, a left turn lane for northbound traffic would be provided at the intersection with Tamarack Road. In addition, the existing 8-foot wide bituminous trail within the westerly boulevard would be rehabilitated by means of full pavement removal and replacement.
III. PERMITS AND EASEMENTS REQUIRED A sanitary sewer extension permit from the Minnesota Pollution Control Agency (MPCA) is not required since we are replacing the existing sewer with new sewer of the same or smaller size. However, a water main permit is required from the Department of Health for the proposed water main improvements. Upper Afton Road is located within the Ramsey/Washington/Metro Watershed District (RWMWD). Because this project disturbs more than 1 acre, an RWMWD permit is required, as well as an MPCA Construction Stormwater permit. Finally, a permit from Washington County would be required for the loop detector replacement on Upper Afton Road at Century Avenue (C.S.A.H. 25). All proposed work is located on public right-of-way or City owned land. Permanent or temporary easements are not anticipated to be necessary to accomplish the proposed improvements. However, a right of entry would be needed from each property that is getting a new sanitary sewer and water service.

Prepared by: Bolton & Menk, Inc. COST ALLOCATION 2019 Roadway Rehabilitation Project – Upper Afton Road ǀ BMI Project No. N12.116537 Page 5
V. COST ALLOCATION Upper Afton Road is classified as a collector street. It is proposed that the project costs for Upper Afton Road be assessed to the benefited properties utilizing the City’s current rehabilitation financing policy, Council Directive CD-ENGPW-4.3, adopted December 10, 2014. Attached Figure 2 shows the properties proposed to be assessed for the improvements. The land use adjacent to Upper Afton Road consists mostly of residential property. There are also four commercial properties and five public/semi-public properties. For collector streets located within the Metropolitan Urban Service Area (M.U.S.A.), the City’s policy requires properties with adjacent footage on a street being rehabilitated to pay the following percentage of the improvement costs, based on the type of land use:
Type of Land Use
Percentage of Street and Storm Sewer
Costs Assessed to Property
Percentage of Sanitary Sewer, Water Main Storm Sewer Maintenance,
and Storm Water Quality Costs Assessed to Property
Commercial 90% 0%
Public/Semi-Public 75% 0%
Residential 33% 0%
Park and Open Space 100% 0%
As shown in the previous table, the City would be responsible for 100% of the costs of the sanitary sewer, water main, storm sewer maintenance, and storm water quality improvements, along with all costs assigned to the Park and Open Space properties. This is consistent with current City policy. For commercial, public/semi-public, and park/open space properties, the appropriate percentage of improvement cost would be assigned to each property based on its adjacent footage on the street being improved. The cost would be determined by multiplying the cost per adjacent foot by the length of adjacent footage. For residential properties with front yard frontage or direct access (i.e. private street or private driveway) to the street being improved, the street improvement cost would be assigned on a per unit basis and would be determined by multiplying the cost per adjacent foot by the total adjacent residential property frontage and dividing by the total number of residential units. Residential properties with side yard or rear yard frontage along Upper Afton Road would not be assessed for this project. In addition, the Park and Open Space parcels will not be assessed, as they are owned by the City and will be included as City costs in this report. There are 13,309 feet of adjacent footage along Upper Afton Road, between Century Avenue and Weir Drive, consisting of 6,599 feet of assessable frontage and 6,710 feet of non-assessable frontage. Included in the non-assessable frontage is residential side yard or rear yard frontage, public right-of-way at various intersections, and all park and open space properties. A list of the property owners to be assessed, and their adjacent footage, is shown in the following table:

Based on the current assessment policy, residential properties would only be responsible for 33% of the street and storm sewer improvements of a typical 32-foot wide residential equivalent street. As part of the 2015 Roadway Rehabilitation Project (City Project No. 09-2014-02), the cost to reconstruct a 32-foot wide residential equivalent street was determined. As of December 2014, the cost per adjacent foot was $38.75 for storm sewer and $168.19 for streets. As shown in appendix C, the cost per adjacent foot based on current unit prices is $50.32 for storm sewer and $175.27 for streets. Since the storm sewer in the table above ($21.62) is less than the storm sewer for a residential equivalent street ($50.32), only the street improvements would be applicable.

The total residential assessment of $241,363.55 in the previous table would be divided equally amongst the residential properties on an equivalent residential unit (ERU) basis. Each of the 16 single-family properties would be considered one ERU. There are three more residential properties that are currently large, undeveloped parcels. It is proposed to convert the frontage of these three parcels to ERUs based on an average residential lot width of 80 feet. The total number of ERUs for the undeveloped parcels are calculated in the following table. Note that the ERU’s are rounded down to the nearest unit since the portion of an additional lot would not be buildable.

The City of Woodbury has implemented a minimum residential assessment rate for reconstruction projects. The rate applies to the street and storm sewer portions only. As of August 2017, the rate was $2,607 per single-family unit. Based on the Engineering News Record (ENR) Construction Cost Index for Minneapolis, the current rate updated from August 2017 to August 2018 would be: $2,607 x (13031.83 ÷ 12602.94) = $2,696 per Single Family Based on a previous table, the total single-family assessment for storm sewer and streets is $662.20 + $5,371.89 = $6,034.09 per unit, which is more than the minimum assessment of $2,696 per unit. Therefore, the minimum assessment wouldn’t apply in this case.

VIII. FEASIBILITY, NECESSITY, AND COST EFFECTIVENESS The following table compares the cost per linear foot of this project versus the costs shown in the preliminary reports of other similar rehabilitation projects recently constructed within the City:
Project Cost Comparison
Project Cost per Linear
Foot
Pioneer Drive (Hargis Parkway to Dale Road) $865
2016 Roadway Rehabilitation - Pioneer Drive $950
2019 Roadway Rehabilitation - Upper Afton Road $857

Project Cost per Linear
Foot
Pioneer Drive (Hargis Parkway to Dale Road) $865
2016 Roadway Rehabilitation - Pioneer Drive $950
2019 Roadway Rehabilitation - Upper Afton Road $818
Based on the previous table, the cost to rehabilitate Upper Afton Road is less than previous projects. This is due to the fact that the road is being reconstructed to a width similar to the existing width. Minimal additional costs are needed for the minor widening. This project is financially feasible. Financial responsibilities have been determined based on estimated project

costs and adopted City policy. Funding sources consist of assessments to benefitted properties and use of existing designated City funds. The disturbance caused by the removal and replacement of the existing water main and sanitary sewer necessitate a full reconstruct of the street section. The improvements are cost effective as they keep existing sanitary sewer and storm sewer wherever possible. From an engineering standpoint, this project is feasible, necessary, and cost effective.
IX. PUBLIC HEARING This project will be partially funded by assessing the benefitted properties. Therefore, the City will need to hold a public improvement hearing to receive comments on the proposed project and to determine what further action should be taken. For purposes of the hearing, the following information should be utilized: Estimated Project Cost: $5,765,563 Total Assessed Cost: $949,884.75 Benefited Area: All residential parcels within Section 6 or the northeast quarter of Section 7, Township 28N, Range 21W, City of Woodbury, County of Washington, State of Minnesota that have direct driveway or private street access to Upper Afton Road, and all commercial and public/semi-public parcels within the same area that are immediately adjacent to Upper Afton Road.
X. RECOMMENDATIONS It is recommended that this report be used as a guide for the layout, design and cost allocation for the public improvements to be made as part of the 2019 Roadway Rehabilitation – Upper Afton Road project. It is further recommended that the owners of properties within the project limits be properly notified of the proposed improvements in order to provide comment.
