Feasibility Report 2023 Pavement Management Program Project FH-23-01 Holton Street, Larpenteur Avenue to Roselawn Avenue Albert Street, Ruggles Street to Roselawn Avenue Sheldon Street, Ruggles Street to Roselawn Avenue Ruggles Street, Holton Street to Hamline Avenue Garden Avenue, from East Snelling Drive to Hamline Avenue Prepared by: Jesse Freihammer City Engineer City of Falcon Heights I hereby certify that this feasibility report was prepared by me or under my direct supervision and that I am a duly Licensed Professional Engineer under the laws of the State of Minnesota. ___________________________________________, P.E. Licensed No. 47272 2023 Pavement Management Project October 26, 2023 Feasibility Report 1 EXECUTIVE SUMMARY This feasibility report has been prepared for the 2023 Pavement Management Project, FH 23-01. The project was initiated by council/staff as part of the City’s Pavement Management Program. This report consists of a detailed investigation of the streets proposed for improvements, listed below. A map showing the street locations can be found on Page 4. Area 1 - Mill and Overlays Area 1 of the proposed project involves milling the pavement, spot curb replacement, spot utility improvements and pavement replacement. Utility improvements for the project include the repair of selected storm sewer manholes and catch basins. As has been discussed during development of the CIP, the City Council has expressed the desire to complete maintenance on City streets that, if neglected for too long, would need to be reconstructed. The proposed mill and overlays included in the 2023 PMP achieves this, while also maintaining a neighborhood approach to minimize the inconveniences residents experience due to construction. Streets include: • Holton Street, Larpenteur Avenue to Roselawn Avenue • Albert Street, Ruggles Street to Roselawn Avenue • Sheldon Street, Ruggles Street to Roselawn Avenue • Ruggles Street, Holton Street to Hamline Avenue Area 2 - Reconstruction Garden Avenue, from East Snelling Drive to Hamline Avenue, is proposed for pavement reclamation to address deficiencies in the pavement and base section of the roadway. This area is proposed for a significant amount of curb removal. Also proposed are impacted driveway replacements, and minor storm sewer and sanitary sewer work. The existing street design changes at Holton so staff recommends Council look at the new options as two segments. Segment 1 is west of Holton, Segment 2 is east of Holton and includes the elementary school. Different decisions can be made on the width of the roadway and if a pathway should be installed for each segment. The decisions can be made independent for each segment. Roadway Geometry was examined for benefits, including lowering driver speeds and decreasing stormwater run-off. Reduction of the roadway width would result in some loss of parking. Pathway Installation on the north side of the street was examined. Previous Council Action determined, if a pathway is installed with this project, costs would not be assessed and snow removal would be done by City staff. All proposed sidewalk options are located within the existing curb line so no further impacts to residents’ yards or loss of driveway space would occur, even though the City has additional right of way and could exercise this right. Segment 1 – Options • Option 1 (Existing Street Design) o Street Width 36 Feet 2023 Pavement Management Project October 26, 2023 Feasibility Report 2 o 11-foot Drive Lanes o 7-foot Parking Lanes on Both Sides o No Sidewalk • Option 2 (Existing Street Design Modified) o Street Width 36 Feet o 11-foot Drive Lanes o 8-foot Parking Lanes on South Side o 6-foot shoulder on North Side, No Parking o No Sidewalk • Option 3 (Concept B modified) o Street Width 34 Feet (Narrowed 2 Feet by Moving the North Curb) o 11-foot Drive Lanes o 7-foot Parking Lane on South Side o 5-foot shoulder on North Side, No Parking o No Sidewalk • Option 4 (Concept A) o Street Width 29 Feet (Narrowed 7 Feet by Moving the North Curb) o 11-foot Drive Lanes o 7-foot Parking Lane on South Side o 7-foot Sidewalk on North Side, Next to the Curb Segment 2– Options • Option 5 (Existing Design) o Street Width 42 feet o 12-foot Drive Lanes o 9-foot parking South Side Only o 9-foot Shoulder North Side Currently Signed No Parking. o No Sidewalk • Option 6 (Concept G) o Street Width 32-foot (Narrowed 10 Feet by Moving North Curb) o 12-foot Drive Lanes o 8-foot Parking South Side Only o Elimination of North Shoulder Currently Signed No Parking. o No Sidewalk o East of School Property: North Side Shoulder for School Pick-Up Queuing, No Sidewalk • Option 7 (Concept F) o Street Width 32-foot (Narrowed 10 Feet by Moving North Curb) o 12-foot Drive Lanes o 8-foot Parking South Side Only 2023 Pavement Management Project October 26, 2023 Feasibility Report 3 o Elimination of North Shoulder Currently Signed No Parking. o 6-foot Sidewalk o 5-foot Boulevard Between Sidewalk and Curb Adjacent to the School Property o East of School Property: North Side Shoulder for School Pick-Up Queuing, 7-foot Sidewalk, No Boulevard o Bumpouts at Intersection to Eliminate Parking Near Intersection/Shorter Pedestrian Crossings Ruggles Pathway Connection The right-of-way connecting Ruggles Avenue from Pascal Street to Holton Street was evaluated for a pathway. The existing right of way is 12 feet wide. The existing surface is unimproved so access can be limited to some users, particularly those in wheelchairs or those who are less mobile. Options for this pathway include installing a concrete sidewalk, installing a permeable paver sidewalk or doing no improvements. If improvements are not completed, consideration of vacating the right of way could be considered since the unimproved segment would not meet ADA standards. Project Cost The total project cost for Falcon Heights is estimated to be $1,688,000 if sidewalks are fully installed on Garden Avenue. This also includes contingencies and overhead costs. If Ruggles pathway was added, this would add between $35,000 and $51,000 to the costs. This estimate applies to all options but is the highest cost scenario. All the street cost options are generally the same with only some minor estimated reductions. Funding for the project will be provided through assessments from the benefitting properties, utility funds, street infrastructure funds, and Municipal State Aid (MSA) funds. A summary of the estimated project costs and funding sources are as follows: Mill and Overlay Street Costs: $427,000 Garden Avenue Street Costs: $680,000 Garden Ave Sidewalk (West): $172,000 Garden Ave Sidewalk (East): $127,000 Storm Sewer Costs: $242,000 Sanitary Sewer Costs: $ 40,000 Funding: Approximated Assessments: $533,000 Street Fund: $287,000 Municipal State Aid: $586,000 Storm Sewer Fund: $242,000 Sanitary Sewer Fund: $ 40,000 Project Schedule If this project is approved, the proposed project schedule is shown below.

From historical aerial photos, Garden Avenue was originally a gravel section line road It was widened to its current configuration in 1976. The last time the roadway was resurfaced was in 1999. All streets have an urban design with concrete curb and gutter and stormwater systems to convey drainage. Holton Street, Albert Street, Sheldon Street and Ruggles Avenue are residential streets. They are 31 feet wide, with parking allowed on both sides. The speed limit for these streets is 20 mph and staff are not aware of a speeding issue, nor have they received residents’ comments about speeds. Garden Avenue is a Municipal State Aid route and is classified as a minor collector. From the Snelling Service Road to Holton Avenue it is 36 feet wide with two lanes of traffic, parking on both sides, with parking restrictions in front of the church. From Holton to Hamline the roadway transitions to a 42-foot-wide street with no parking posted on the north side. parking restrictions in front of the school. between the school and Holton Street and near the church on Holton Street. Garden Avenue has pavement markings that are not consistent with the Minnesota Manual of Uniform Traffic Control Devices (MUTCD) at the intersection with Albert Street. Garden Avenue has a school zone with a 20-mph speed limit and a 20-mph speed limit west of Holton Street. The school zone speed limit is out of date since the City updated the posted speed limit on Garden to 20 mph in 2021. Garden Avenue speed counts from May 2022 measure the 85th percentile speed at 27 mph near Simpson Street and 24 mph near Falcon Heights Elementary School. The measured speeds represent a significant speeding issue although based on the new speed limit. Staff has heard numerous resident concerns about speeding vehicles on Garden Avenue. Municipal State Aid (MSA) traffic counts taken in 2020, during the COVID-19 Pandemic, measured 610-620 Average Daily Traffic (ADT) on Garden Avenue. Staff took additional counts in May of 2022 and measured 743-748 ADT (not seasonally adjusted by MnDOT Traffic). The MSA traffic counts taken in 2017, pre-pandemic, measured 790-1050 ADT. Traffic volumes on Garden Avenue appear to be increasing, but are not back to pre-pandemic volumes. Pavement condition scores were considered to determine the streets for the City’s pavement management and capital improvements plan. Falcon Heights’ pavement management system utilizes a pavement condition index (PCI) rating of 0 to 100. This rating is based on surficial pavement observations. Street condition ratings are divided into three categories: “adequate” (66 to 100), “marginal” (36 to 65) and “problem” (0 to 35). The average PCI for Garden is 20. The average PCI for the mill and overlay roads is 47. Falcon Heights contracted with a geotechnical engineering consultant to obtain pavement borings on Garden Avenue within the project. The observed pavement depth was generally 4 inches. The Figure 1 - Non-Standard Painted Cross-Hatch 2023 Pavement Management Project October 26, 2023 Feasibility Report 7 thicker pavement observed at one of the borings was likely due to a roadway patch. Observed aggregate base ranged from 4 to 7 inches. The fill encountered below the base consisted of sandy soils. The geotechnical report indicated the pavement distresses on Garden Avenue may indicate issues within the subgrade of the roadway. Slightly organic soils were encountered at one of the locations 2-4 feet below the street surface. The fill contained some debris, including concrete and bituminous. The existing pavement sections are summarized in the table below: Measured Existing Pavement Sections Table Boring Location Bituminous Pavement Thickness (in.) Apparent Aggregate Base Thickness (in.) ST-8 4 4 ST-9 4.5 7 ST-10 4 6 ST-11 7 5 Proposed Improvements Area 1 Proposed Improvements - Mill and overlaying of the pavement is proposed as the method of pavement construction. The process involves grinding off the top 2 inches of pavement and replacing with two new inches of bituminous. This method is a cost-effective way to get a new pavement surface that is smoother and free of defects. Although cracking is likely to mirror in the year following construction, sealing cracks the following year is anticipated to address that issue and maintain the pavement longevity. Cost for the street resurfacing is estimated at $427,000. Area 2 Proposed Improvements - Falcon Heights contracted with a geotechnical engineering consultant to obtain pavement borings on Garden Avenue. Based on the data and the minimal utility work proposed with this project, a full-depth reclamation is proposed. This would include grinding and mixing the existing pavement with the underlying base section. This strengthens the base of the roadway. Excess grounds are removed and a new, 4-inch asphalt section would be paved without changing the elevation of the roadway. Some areas may need subgrade correction if unsuitable soils are encountered. The road is proposed to be striped with pavement markings consistent with the MN MUTCD. Cost for the street reconstruction is estimated at $680,000 Area 2 Proposed Improvements Options Segment 1, Snelling Service Road to Holton Avenue • Option 1 (Existing Street Design) o Street Width 36 Feet o 11-foot Drive Lanes o 7-foot Parking Lanes on Both Sides o No Sidewalk • Option 2 (Existing Street Design Modified) o Street Width 36 Feet o 11-foot Drive Lanes o 8-foot Parking Lanes on South Side 2023 Pavement Management Project October 26, 2023 Feasibility Report 8 o 6-foot shoulder on North Side, No Parking o No Sidewalk • Option 3 (Concept B modified) o Street Width 34 Feet (Narrowed 2 Feet by Moving the North Curb) o 11-foot Drive Lanes o 7-foot Parking Lane on South Side o 5-foot shoulder on North Side, No Parking o No Sidewalk • Option 4 (Concept A) o Street Width 29 Feet (Narrowed 7 Feet by Moving the North Curb) o 11-foot Drive Lanes o 7-foot Parking Lane on South Side o 7-foot Sidewalk on North Side, Next to the Curb Segment 2, Holton Avenue to Hamline Avenue • Option 5 (Existing Design) o Street Width 42 Feet o 12-foot Drive Lanes o 9-foot Parking South Side Only o 9-foot Shoulder North Side Currently Signed No Parking. o No Sidewalk • Option 6 (Concept G) o Street Width 32-foot (Narrowed 10 Feet by Moving North Curb) o 12-foot Drive Lanes o 8-foot Parking South Side Only o Elimination of North Shoulder Currently Signed No Parking. o No Sidewalk o East of School Property: North Side Shoulder for School Pick-Up Queuing, No Sidewalk • Option 7 (Concept F) o Street Width 32-foot (Narrowed 10 Feet by Moving North Curb) o 12-foot Drive Lanes o 8-foot Parking South Side Only o Elimination of North Shoulder Currently Signed No Parking. o 6-foot Sidewalk o 5-foot Boulevard Between Sidewalk and Curb Adjacent to the School Property All options for reducing the street width involved moving in the north curb line. Garden Avenue is currently 36 feet wide, much wider than the other streets in this neighborhood. The additional width is likely contributing to faster speeds on Garden Avenue. Narrowed roadways can provide more visual feedback for drivers to better interpret the speed they are traveling at, along with feeling less comfortable at higher speeds. 2023 Pavement Management Project October 26, 2023 Feasibility Report 9 Reduction of street width will result in some loss of parking. Based on staff observations and resident feedback, there is ample parking even if one side of parking is eliminated. All options leave at least one side with parking which as feedback received from residents. A significant reduction of the street width without addition of a new sidewalk, such as Option 6 could eliminate current space used by walkers. Pathways Existing Conditions Area 1 and 2 – No pathways are located on the project streets in Area 1 or Area 2. Ruggles Pedestrian Connection – The City has right-of-way parallel to Ruggles Street that is currently used by residents on foot to cut through the neighborhood from Pascal Street to Holton Street. The area is currently maintained by the residents on both sides as lawn, so it does not meet Americans with Disabilities Act (ADA) standards for accessibility. A utility pole is located in the center of the right-of-way. The city has no formal count of usage but anecdotally it is relatively well used during the summer. Proposed Improvements Area 1 – No improvements are proposed. Area 2 Segment 1 Option 4 identified under the STREETS segment is the only option for this segment that has a dedicated separated pathway. This option provides a 7-foot concrete sidewalk behind the new north curb line. Dedicated pathways such as this option provide a higher level of safety compared to shared space within the roadway where pedestrians and bikers would use the parking lane or shoulders. It defines where pedestrians should walk. The sidewalk is elevated behind a curb which acts as a barrier. As long as the pathways are plowed in the winter, it provides a much safer space as typically shoulders get reduced as snow builds up and pavement markings get hidden under the snow. Estimated improvement cost is $172,000. Area 2 Segment 2 Option 7 identified under the STREETS segment is the only option for this segment that has a dedicated separated pathway. This option provides a 6-foot concrete sidewalk separated by a 5 foot boulevard behind the new north curb line. This option provides room for snow storage between the curb and the sidewalk. Dedicated pathways such as this option provide a higher level of safety compared to shared space within the roadway where pedestrians and bikers would use the parking lane or shoulders. It defines where pedestrians should walk. The sidewalk is elevated behind a curb which acts as a barrier. As long as the pathway are plowed in the winter, 2023 Pavement Management Project October 26, 2023 Feasibility Report 10 it provides a much safer space as typically shoulders get reduced as snow builds up and pavement markings get hidden under the snow. Estimated improvement cost is $127,000. Council action has determined, if a pathway is installed with this project, costs would not be assessed. This report assumes the funding would be split between Municipal State Aid and the Street Fund. Ongoing maintenance, including snow removal would be performed by the City. Ruggles Pedestrian Connection – An improvement to the Ruggles right-of-way was considered. The pathway could be constructed as concrete with drain tile at an estimated cost of $35,000. A second option would be permeable pavers, which allow stormwater to filter through the pavement into the ground below to accommodate drainage. The estimated cost of a permeable paver installation is $51,000. These estimated amounts include contingency and engineering/overhead costs. Due to significant opposition by the adjacent property owners and others living in the neighborhood in addition to the low resident support heard from the neighborhood, current usage of the connection and the cost of the improvement construction, the pathway is not recommended. However, ongoing discussions are happening around this proposal as additional meetings are occurring with neighbors. If a pathway were constructed, costs of the 2023 PMP would increase by $35,000 to $51,000, funded from the street fund. Sanitary Sewer Existing Conditions The sanitary sewer system within the project streets was constructed in the 1950s and 1960s. All of the sanitary pipe has been lined with Cure-In-Place-Pipe through the City’s sanitary sewer rehabilitation program. This process creates a new pipe within the existing pipe. Proposed Improvements The sanitary sewer manholes are proposed for minor rehabilitation work to include new, water- tight castings and lids, new concrete rings and installation of an inflow and infiltration barrier at the top of the manhole. These improvements are anticipated to reduce stormwater entering the sanitary sewer system, which increases downstream capacity and treatment costs. They will also reinforce the top of the manhole to prevent future settlements within the street. The cost estimate for these improvements is $40,000. 2023 Pavement Management Project October 26, 2023 Feasibility Report 11 Stormwater and Drainage Existing Conditions The streets in the project area are served by catch basins which collect water on the street and transport it to the east into Roseville. Storm sewer structures within the project area were constructed with various materials including brick and mortar, concrete barrel sections seated on top of pipe, and more conventional concrete structures. Catch basins on Garden Avenue are located behind the curb line, which cause maintenance issues with keeping the drain open for water in the winter and spring months. Staff inspected all storm structures to evaluate their condition and determine replacement priorities. The project area eventually flows east across the City line to a known flooding area, Gottfried Pit, located in Roseville at Larpenteur Avenue and Fernwood Avenue. Gottfried Pit is a regional pond that is owned by Ramsey County, and maintained by the City of Roseville. In extreme events, the pond has flooded up to approximately the 912 elevation (approximately 16’ above the normal water level). Proposed Improvements Based on staff inspection, deteriorated catch basins will be rehabilitated or replaced as part of the proposed project improvements. During design, catch basins may be added to alleviate drainage issues or redundant catch basins may be eliminated. Catch basins located behind the curbline on Garden Avenue are proposed to be removed or converted and new catch basins are proposed within the curbline. If Option 1B is selected, catch basins will be constructed within the north curbline relocation. The cost estimate for these improvements is $242,000. As the proposed street improvements would disturb an area greater than one acre, the project is required by the Minnesota Pollution Control Agency (MPCA) to include a Storm Water Pollution Prevention Plan (SWPPP) and use erosion and sediment control best practices during construction, and obtain an MPCA Construction Permit. A watershed district erosion and sediment control permit will also be required. The proposed improvements would not add enough impervious surface that would trigger watershed district quality or quantity requirements. Option 1B, to narrow the roadway, would reduce impervious surface in the area, reducing stormwater conveyed downstream to Gottfried Pit. No improvements for stormwater treatment are proposed with this project. RIGHT-OF-WAY AND EASEMENTS These project improvements are proposed within the existing right-of-way. No right-of-way or easement acquisition is anticipated. 2023 Pavement Management Project October 26, 2023 Feasibility Report 12 If the Ruggles Street right-of-way between Pascal Street and Holton Street is not going to be improved to be an ADA-compliant pathway, the Council may consider vacation of the right-of-way. Failure of Falcon Heights to meet the requirements of the Americans with Disabilities Act on a travel-way within City right- of-way may be a liability for the City. Vacation or turning-back the right-of-way may be appropriate to address the liability concerns. The vacation process is prescribed by Minnesota State Statute as a discretionary act of the Council. It can be initiated by the City and approved by City Council with a four-fifths majority at a public hearing. Prior to the hearing, notice must be sent to affected property owners and notice posted and published in the City newspaper. The right-of-way area at issue is not land owned by the City. It is a platted right-of-way easement over land. A vacation process would remove the City’s right-of-way easement over the property, “turning back” the property to the underlying property at no cost to them. The property would then be available for their use and enjoyment. The property would also be returned to the tax roll. OUTSIDE AGENCY COORDINATION The watermain system that services the project area is owned and operated by St. Paul Regional Water Services and they have indicated no improvements are planned for inclusion or coordination with this project. The project area is within the Capitol Region Watershed District. Proposed improvements are not anticipated to warrant any stormwater requirements from the District. During the design process, staff will do a Gopher State One Call for the project area to identify all small utility operators. The City will coordinate with small utilities to finalize relocates and other coordination items during design. ESTIMATED COSTS AND PROPOSED FUNDING Proposed project costs for the 2023 PMP Improvement Project are summarized below. The cost estimate is based on recent construction projects of similar character and assumes that the proposed improvements would begin in 2023. All costs include estimated engineering costs and 15% contingency, which includes unforeseen costs including inflation, unforeseen site conditions, etc. Actual costs will be determined through competitive bids following final design for the project. The actual costs will be dependent upon the market conditions that exist at the time of the bidding. The proposed street improvements are eligible for assessments according to the City of Falcon Heights Assessment Policy. Per City Policy, a portion of the street improvements will be assessed to the benefitting properties. Along with assessments, street costs will be financed through the Street Infrastructure Fund and Municipal State Aid. Typically, only roads that have been added to the City’s Municipal State Aid system (MSA) are eligible for funding through the City’s portion of state gas tax revenues. However, the City of Falcon Heights has a Certified Municipal State Aid Street system. As a result, the City can use MSA funds to pay for the City’s portion of the costs. Storm sewer and sanitary sewer improvements will be funded from the appropriate infrastructure fund, and are not eligible for assessments. 2023 Pavement Management Project October 26, 2023 Feasibility Report 13 Estimated Cost MSA Street Infrastructure Funds Assessments Sanitary Sewer Fund Storm Sewer Fund Street Improvements – Area 1 $427,000 $117,000 $117,000 $193,000 - - Street Improvements – Area 2: Garden Ave $680,000 $170,000 $170,000 $340,000 - - Storm Sewer Improvements $242,000 - $242,000 Sanitary Sewer Improvements $40,000 $40,000 - Total $ 1,389,000 $287,000 $287,000 $533,000 $40,000 $242,000 *Includes 15% Engineering If a pathway is installed with this project, the Council has directed staff not to assess project costs. This report assumes the funding for pathway improvements would be split between Municipal State Aid Funding and the Street Infrastructure Fund. This is consistent with past practice; the City did not assess for pathway replacement along Roselawn Avenue in 2015. The table below shows the estimated costs with contingency and funding for the pathway options. Estimated Cost MSA Street Infrastructure Funds Assessments Options 1, 2, 3, 5, 6 No Pathway Improvements $0 - - - Option 4 $172,000 $86,000 - - Option 7 $127,000 $127,000 - - Option 4 and 7 $299,000 $299,000 - - No Pathway at Ruggles Right-of-Way $0 - - - Ruggles: 5-Foot Concrete Pathway $35,000 - $35,000 Ruggles: Permeable Pavers $51,000 - $51,000 - *Includes 15% Engineering PROPOSED ASSESSMENTS Assessments will be levied to the benefitting properties as outlined in Minnesota State Statute Chapter 429 and the City’s Assessment Policy, which is summarized below. The assessed amount is levied on a front footage basis. Residential corner lots are assessed 100% for the long side, 0% for the short side. One alteration proposed to the policy considers the long, narrow lots between Albert Street and Hamline Avenue. Tax-exempt lots are assessed for all frontages. To be consistent with the assessment practice used on the 2015 PMP, which also included a lot with significant length, residential lot depth is proposed 2023 Pavement Management Project October 26, 2023 Feasibility Report 14 to be capped at 176 feet. This would affect two lots lowering their assessible frontage from 296 feet to 176 feet. Assuming this project is completed by fall 2023, the final assessment amount would be determined at an assessment hearing in the fall of 2023 with a thorough review of the proposed assessments by the Council. The Council would also set the length of assessments and the interest rate at the hearing. In past projects, the assessments have been over 7 years for mill and overlay projects and 10 years for reconstruction projects at an interest rate 2% above the current rate of return on the City’s portfolio. The following factors regarding the City of Falcon Heights assessment policies should be considered: • The properties owned by the Falcon Heights UCC are tax-exempt parcels, and have been included in the preliminary assessment roll as such. The City may choose to pursue a benefit appraisal on the properties to ensure the assessment proposed does not exceed the estimated benefit to the property, as required by Minnesota State Statute 429. This may result in a higher City cost, which could be offset by using additional State Aid funds. Staff will update the City Council as information becomes available. • Garden Avenue assessments are higher than they would be for a similar project on a north-south street due to the orientation of the lots. The majority of the adjacent lots have their long side on Garden Avenue. This means they were not assessed for the improvements to the street on their short side, but, in accordance with the assessment policy, they will have a long assessable frontage. Area 1 – Holton Street, Albert Street, Sheldon Street, Ruggles Avenue This area includes 8,705 feet of frontage, 504 feet of which is not assessable due to corner lots. There are 96 parcels eligible for assessment. The average residential assessment is estimated at $1,495.34. The estimated assessment rates are shown below: • Residential (40% of the improvement cost) = $19.62/ft • Tax-Exempt (100% of the improvement cost) = $49.05/ft Area 2 – Garden Avenue This area includes 4,241 feet of frontage, 553 feet of which is not assessable due to corner lots. There are 22 parcels eligible for assessment. The average residential assessment is estimated at $8,844.57. The estimated assessment rates are shown below: • Residential (40% of the improvement cost) = $64.14/ft • Tax-Exempt (100% of the improvement cost) = $160.34/ft No assessments are proposed for funding pathways, if constructed. PUBLIC INVOLVEMENT The City hosted two open houses for the Northeast Quadrant as a whole, on April 5, 2022 and July 20, 2022, to discuss the Ruggles Street pathway proposal and Garden Avenue. These open houses were widely attended by both residents adjacent to the proposed improvements and also residents from other Northeast Quadrant streets. Layouts with project concepts were available for viewing and discussion. 2023 Pavement Management Project October 26, 2023 Feasibility Report 15 The residents expressed concerned about assessment cost, snow maintenance and impact on their yard of the pathway options. Several residents who live on Garden Avenue didn’t see a need for a sidewalk as people currently walk on the street. Residents had concerns about speeding on Garden Avenue. They also expressed desire to have parking on Garden Avenue. Comments received are summarized and written comments are attached in the Appendix. An informational meeting was held on October 5, 2022 for residents who live adjacent to the project streets and Ruggles pathway option. Approximately 10 people attended. The meeting was presentation format, where staff presented information on the City’s Pavement Management Program, the proposed improvements, and the City’s Assessment Policy. Residents asked clarifying questions about the City’s assessment policy, the history of Garden Avenue, and about pedestrian facilities. As Garden Avenue was proposed for improvement in 2015, a Garden Avenue resident asked why they should bear a higher assessment cost for construction in 2023.

Purpose The purpose of our geotechnical evaluation was to core the existing pavement, characterize the subsurface soil conditions at selected exploration locations, evaluate their impact on the project, and provide geotechnical recommendations for use in the design and rehabilitation of the selected roadways. A.4. Background Information and Reference Documents We reviewed the following information:  Proposed 2023 Pavement Management Map, furnished by the City of Roseville and dated March 8, 2022. In addition to the provided source, we have used several publicly available sources of information including topography maps obtained from the Minnesota Department of Natural Resources (MnTOPO website) and Google Earth aerial photographs. We have described our understanding of the proposed construction and site to the extent others reported it to us. Depending on the extent of available information, we may have made assumptions based on our experience with similar projects. If we have not correctly recorded or interpreted the project details, the project team should notify us. New or changed information could require additional evaluation, analyses and/or recommendations. A.5. Scope of Services We performed our scope of services for the project in accordance with our Proposal for a Geotechnical Evaluation (QTB156087) dated April 4, 2022. The following list describes the geotechnical tasks completed in accordance with our authorized scope of services.  Reviewing the background information and reference documents previously cited.  Staking and coordinating clearing the exploration location of underground utilities. The City of Falcon Heights selected and we staked/marked the new exploration locations in the field. We acquired the surface elevations and locations with GPS technology using the State of Minnesota’s permanent GPS base station network. The Soil Boring Location Sketch included in the Appendix shows the approximate locations of the borings. City of Falcon Heights Project B2203417 June 13, 2022 Page 4  Performing 11 standard penetration test (SPT) borings, denoted as ST-1 through ST-11, to nominal depths of 5 feet below grade across the site.  Core the pavement at each boring location for a total of eleven pavement cores.  Performing laboratory testing on select samples to aid in soil classification and engineering analysis.  Preparing this report containing a boring location sketch, logs of soil borings, a summary of the soils encountered, results of laboratory tests, and recommendations for reconstruction/rehabilitation of the existing roadways and pavement design thicknesses. Our scope of services did not include environmental services or testing and our geotechnical personnel performing this evaluation are not trained to provide environmental services or testing. We can provide environmental services or testing at your request. B. Results B.1. Geologic Overview We based the geologic origins used in this report on the soil types, laboratory testing, and available common knowledge of the geological history of the site. Because of the complex depositional history, geologic origins can be difficult to ascertain. We did not perform a detailed investigation of the geologic history for the site. B.2. Visual Field Observations We performed a site visit to visually observe the conditions of the existing pavements across both project areas following completion of the field work and laboratory testing. Visual observations, in combination with the results of the geotechnical evaluation, can offer additional insight into the subgrade conditions in areas where soil borings were not completed. In addition, these visual observations of the existing pavements can help determine the practicality of different rehabilitation options and how the previous pavement section has held up since its previous improvements. City of Falcon Heights Project B2203417 June 13, 2022 Page 5 In the Falcon Woods area (Borings ST-1 through ST-7), significant surface distress in the form of surface cracks and some raveling was observed throughout the entire project area. In general, minimal amounts of potholes and rutting were observed with localized areas exhibiting more distress, specifically rutting along Summer Street between Prior Avenue and Howell Street and potholes near the intersection of Howell Street and Prior Avenue. The roadways showed previous signs of maintenance, including bituminous patches and sealed surface cracks. The Garden Avenue project area (ST-8 through ST-11) showed significant signs of distress in the form of surface cracks and raveling with occasional potholes throughout. Rutting was observed throughout the project area but was more heavily concentrated on the western half of Garden Avenue. The roadway showed previous signs of maintenance, including bituminous patches and sealed surface cracks. The adjacent curb and gutter also showed signs of distress in the form of settlement. B.3. Existing Pavement Sections Table 3 below outlines the existing pavement section thicknesses that were encountered during our geotechnical exploration. Table 3.

Therefore, we cannot conclusively determine if the encountered material satisfies a particular specification. B.4. Boring Results Tables 4 and 5 provides a summary of the soil boring results in the general order we encountered the strata. Please refer to the Log of Boring sheets in the Appendix for additional details. The Descriptive Terminology sheets in the Appendix include definitions of abbreviations used in Tables 4 and 5.

Fill SM, SP-SM 9 to 50 BPF  Observed below the pavement sections and extended to the termination depths of the borings.  Fill consisted of sandy soils.  Moisture conditions were generally moist.  Slightly organic fill soils were encountered in boring ST-11 at a depth ranging from approximately 2 to 4 feet below existing grade.  Existing fill contained variable amounts of debris, including concrete debris. For simplicity in this report, we define existing fill to mean existing, uncontrolled, or undocumented fill. B.5. Groundwater We did not observe groundwater while advancing our borings. Therefore, it appears that groundwater is below the depths explored. Project planning should anticipate seasonal and annual fluctuations of groundwater. Should a more accurate determination of groundwater be needed, we recommend the completion of additional soil borings and the installation of piezometers. B.6. Laboratory Test Results The boring logs show the results of the laboratory testing we performed next to the tested sample depth. The moisture content of select fill soil samples ranged from 3 to 14 percent moisture by weight. Sieve analysis tests (passing the No. 200 sieve only) performed on select fill soil samples indicated between 5 to 44 percent particles passing the No. 200 sieve by weight. Organic content tests performed on select City of Falcon Heights Project B2203417 June 13, 2022 Page 8 samples indicated between 1 to 2 percent organic material, by weight. These percentages classify the material as non- to slightly organic. C. Recommendations C.1. Design and Construction Discussion C.1.a. Understanding of Project Scope Based on the provided request for proposal dated March 28, 2022, we understand that the City of Falcon Heights is considering cost efficient improvements to the project areas consisting of pavement rehabilitation options and possible reconstruction should the conditions warrant. We assume there will likely not be any utility improvements or large-scale subgrade improvements planned during these improvement projects. We expect that pavement rehabilitation options will be the first choice of the City of Falcon Heights. C.1.b. General Pavement Conditions Generally, pavement distress observed throughout the project site appears to be in the form of alligator cracking, some potholes, etc. Some rutting was observed in the Falcon Woods neighborhood but on a relatively minor scale. More significant rutting was observed in the Garden Avenue area. Both project areas showed previous signs of maintenance, including bituminous patches and sealed surface cracks. C.1.c. Observations of Subgrade Soils Subgrade soils in the Falcon Woods project area generally consisted of sandy fill subgrade soils with some zones of clay-based soils observed. The Garden Avenue project area generally contained sandy subgrade fill soils. Some debris, including concrete and bituminous, was encountered across both project areas. Based on the soil boring samples, the subgrade soils contain minimal organic material within the explored depths. C.1.d. Pavement Improvement Options Several options are available for pavement improvement. One option available is full reconstruction, which includes full removal of the existing pavement section, preparation of the subgrade soils (as needed), and placement of a new pavement section. Other options available include Full-Depth Reclamation (FDR), or mill and overlay techniques, which utilize the reuse of the existing pavement to reconstruct a new pavement section. These approaches do not include full removal of the existing pavement section and limits the opportunity to observe and improve the subgrade soils. City of Falcon Heights Project B2203417 June 13, 2022 Page 9 While the latter two approaches tend to be more economical, there is a small risk that unforeseen deficiencies in the existing subgrade may lead to future pavement impacts. If subgrade performance is expected to be an issue in the future, rehabilitation options may not be practical or economical to perform and will likely not provide the highest quality pavement over the long term. If observation of the existing subgrade soils are a priority, we recommend reconstruction of the existing pavement section. This option would provide the highest quality pavement over the longest possible service life but is typically more expensive than other rehabilitation options. We would recommend the existing bituminous pavement and aggregate base layers be removed, the existing subgrade recompacted and minor soil corrections performed as needed, and a new pavement section, including bituminous and aggregate base, be placed. C.2. Pavement Improvement Recommendations The following sections provide our recommendations for each of the proposed improvement areas discussed in the RFP. In addition to our recommended approach, we understand there may be cost implications to the city. We encourage the city to investigate multiple approaches to improving the pavements, while understanding that each approach has a slightly different life cycle and subsequent maintenance cycle. While one approach may be the most cost-effective in the short term, the maintenance program may be more involved and have higher cost in the future. C.2.a. Pavement Improvement Approach – Falcon Woods Area (ST-1 through ST-7) Based on the results of our exploration, it appears that the existing pavement has reached the end of its lifespan. Based on the type of distress noted in the pavements, and the results of our subsurface exploration, it appears that the existing subgrade is generally sandy in nature and does not appear to be in need of major improvement. Therefore, pavement improvement techniques such as a mill and overlay, or a full-depth reclamation are feasible options. As noted previously, these techniques do not allow for observations of the underlying subgrade soils and improvements to the subgrade. The design team should analyze the cost and practicality associated with each option and choose the option that will best suit the budget, schedule, lifespan, and performance standards for the project. These options will often require more frequent maintenance compared with a full pavement reconstruction but are typically more cost effective during construction. To perform an FDR of the existing pavements, the full thickness of the existing asphalt is pulverized and blended with a portion of the existing apparent aggregate base to form a new base layer for future asphalt placement. We recommend leaving a nominal section of the existing aggregate base layer in place so the underlying subgrade soils are not incorporated into the reclaimed material. The table below City of Falcon Heights Project B2203417 June 13, 2022 Page 10 provides recommended reclamation depths based on the borings performed. Note that pavement section thicknesses are likely to vary, so the contractor should be observing their reclamation during construction and making any necessary adjustments. Table 6. Anticipated reclamation depths for FDR Boring Anticipated Depth (inches) ST-1 6 ST-2 8 ST-3 7 ST-4 7 ST-5 6 ST-6 6 ST-7 6 We recommend that a minimum of 2 inches of aggregate base is left into place during reclamation operations. The contractor should make efforts to not reclaim the entire existing pavement section and disturb the underlying subgrade soils during reclamation operations. FDR is typically more cost efficient to perform as compared to full reconstruction and will eliminate the existing near-surface distresses. We recommend a proofroll is performed once the reclaimed material is at pavement elevations. If areas of unsuitable soils are encountered, it may be difficult, but achievable to perform soil corrections; however the contractor will need to remove and store the reclaimed material to perform any subgrade corrections. C.2.b. Pavement Improvement Approach – Garden Avenue Area (ST-8 through ST-11) Based on the results of our exploration, it appears that the existing pavement has reached the end of its lifespan. Due to the visually observed rutting that is occurring and the higher traffic volumes associated with Garden Avenue, it appears there may be subgrade-related issues contributing the distress observed the pavements. As such, we recommend a complete reconstruction of Garden Avenue, which will provide the highest quality pavement and improve the subgrade conditions simultaneously. We recommend the existing bituminous pavement and aggregate be removed, the existing subgrade recompacted, and a new pavement section, including bituminous and aggregate base, be placed. City of Falcon Heights Project B2203417 June 13, 2022 Page 11 C.3. Site Grading and Excavations This section outlines site grading recommendations for the full pavement reconstruction option as outlined in Section C.2.b. Included are recommendations for engineered fill soil types and classification, as well as compaction recommendations for both engineered fill soils and aggregate base material. C.3.a. Engineered Fill Materials and Compaction Table 7 below contains our recommendations for engineered fill materials. Table 7. Engineered Fill Materials Locations To Be Used Engineered Fill Classification Possible Soil Type Descriptions Gradation Additional Requirements  Pavement areas  Pavement fill SP, SP-SM, SM 100% passing 3-inch sieve <30% passing No. 200 sieve < 2% Organic Content (OC) Plasticity index (PI) < 15% Debris Free  Drainage layer Non-frost-susceptible  Free-draining  Non-frost-susceptible fill  MnDOT select granular SP, SP-SM, SW 100% passing 1-inch sieve < 12% passing #200 sieve See MnDOT 3149.2.B.2 * More select soils comprised of coarse sands with < 5% passing #200 sieve may be needed to accommodate work occurring in periods of wet or freezing weather. We recommend spreading engineered fill in loose lifts of approximately 12 inches thick. We recommend compacting engineered fill in accordance with the criteria presented below in Table 8. The project documents should specify relative compaction of engineered fill. Table 8. Compaction Recommendations Summary - Soil Reference Relative Compaction, percent (ASTM D698 – Standard Proctor) Moisture Content Variance from Optimum, percentage points Granular Soils (SP, SP-SM) Silty Sand Soils (SM) Within 3 feet of pavement subgrade 100 * -2 to +1 More than 3 feet below pavement subgrade 95 * -1 to +3 *The minimum moisture content should be no less than 5 percent and no more than 3 percentage points over optimum. City of Falcon Heights Project B2203417 June 13, 2022 Page 12 Table 9. Compaction Recommendations Summary – Aggregate Base Material Relative Compaction, percent (ASTM D698 – Standard Proctor) Aggregate Base 100 The project documents should not allow the contractor to use frozen material as engineered fill or to place engineered fill on frozen material. We recommend performing density tests in engineered fill to evaluate if the contractors are effectively compacting the soil and meeting project requirements. C.4. Pavements C.4.a. Pavement Subgrade Preparation – Full Reconstruction We recommend the following steps for pavement subgrade preparation, understanding the site will have a grade change of 1 foot or less. Note that project planning may need to require additional subcuts to limit frost heave. 1. Strip unsuitable soils consisting of existing pavements, organic soils, debris-laden soils, existing structures (if encountered), and other unsuitable soils from the area within 3 feet of the surface of the proposed pavement grade. 2. Have a geotechnical representative observe the excavated subgrade to evaluate if additional subgrade improvements are necessary. Based on the results of the borings, the contractor should anticipate that soil correction excavations of the existing fill may be needed to provide a stable subgrade. Where needed, subcuts on the order of 2 to 3 feet should be sufficient in pavement areas at this site. 3. Slope subgrade soils to allow the removal of accumulating water. 4. Scarify, moisture condition, and surface compact the subgrade. 5. Place pavement engineered fill to grade and compact in accordance with Section C.3.d. to bottom of pavement and exterior slab section. See Section C.3.e. for additional considerations related to frost heave. 6. Proofroll the pavement or exterior slab subgrade as described in Section C.2.d. City of Falcon Heights Project B2203417 June 13, 2022 Page 13 C.4.b. Proofroll Observations After preparing the subgrade as described in C.3.a for the Garden Avenue Area prior to placing the aggregate base, and after preparing the reclaimed material in the Falcon Woods areas, we recommend proofrolling the soils with a fully loaded tandem-axle truck. We also recommend having a geotechnical representative observe the proofroll. Areas that fail the proofroll likely indicate soft or weak areas that will require additional soil correction work to support pavements. The contractor should correct areas that display excessive yielding or rutting during the proofroll, as determined by the geotechnical representative. Possible options for subgrade correction include moisture conditioning and recompaction, subcutting and replacement with soil or crushed aggregate, and/or geotextiles. We recommend performing a second proofroll after the aggregate base material is in place, and prior to placing bituminous pavements C.4.c. Design Sections Our scope of services for this project did not include laboratory tests on subgrade soils to determine an R-value for pavement design. Based on our experience with similar soils anticipated at the pavement subgrade elevation, we recommend pavement design assume an average R-Value of 20 for both project sites. Note the contractor may need to perform limited removal of unsuitable or less suitable soils to achieve this value. Tables 10 and 11 provides minimum recommended pavement sections, based on the soils support and traffic loads. We understand that the City of Falcon Heights requires all residential roadways to be designed, at a minimum, as a 7-ton roadway. Table 10. Recommended Minimum Bituminous Pavement Sections – Falcon Woods Area (ST-1 through ST-7) Use 7-ton roadway 7-ton roadway with sand subbase Minimum asphalt thickness (inches) 3 1/2 3 1/2 Minimum aggregate base thickness (inches) 8 6 Minimum granular subbase --- 12 Table 11.

Bituminous Pavement Materials Appropriate mix designs are critical to the performance of flexible pavements. We can provide recommendations for pavement material selection during final pavement design. C.4.e. Subgrade Drainage We recommend installing perforated drainpipes throughout pavement areas at low points, around catch basins, and behind curb in landscaped areas. We also recommend installing drainpipes along pavement where exterior grades promote drainage toward those edge areas. The contractor should place drainpipes in small trenches, extended below the aggregate base material. The draintile systems should be tied to the existing storm sewer system for disposal of water runoff. C.4.f. Performance and Maintenance We based the above pavement designs on a 20-year performance life for pavements. This is the amount of time before we anticipate the pavement will require reconstruction. This performance life assumes routine maintenance, such as seal coating and crack sealing. The actual pavement life will vary depending on variations in weather, traffic conditions, and maintenance. Many conditions affect the overall performance of the exterior slabs and pavements. Some of these conditions include the environment, loading conditions and the level of ongoing maintenance. With regard to bituminous pavements in particular, it is common to have thermal cracking develop within the first few years of placement, and continue throughout the life of the pavement. We recommend developing a regular maintenance plan for filling cracks in exterior slabs and pavements to lessen the potential impacts for cold weather distress due to frost heave or warm weather distress due to wetting and softening of the subgrade. D. Procedures D.1. Penetration Test Borings We drilled the penetration test borings with a truck-mounted core and auger drill equipped with hollow- stem auger. We performed the borings in general accordance with ASTM D6151 taking penetration test samples at 2 1/2- or 5-foot intervals in general accordance with ASTM D1586. The boring logs show the actual sample intervals and corresponding depths. Pavement cores were also collected near each boring location. We sealed penetration test boreholes in general accordance with MDH procedures. City of Falcon Heights Project B2203417 June 13, 2022 Page 15 D.2. Exploration Logs D.2.a. Log of Boring Sheets The Appendix includes Log of Boring sheets for our penetration test borings. The logs identify and describe the penetrated geologic materials, and present the results of penetration resistance and other in-situ tests performed. The logs also present the results of laboratory tests performed on penetration test samples and groundwater measurements. We inferred strata boundaries from changes in the penetration test samples and the auger cuttings. Because we did not perform continuous sampling, the strata boundary depths are only approximate. The boundary depths likely vary away from the boring locations, and the boundaries themselves may occur as gradual rather than abrupt transitions. D.2.b. Geologic Origins We assigned geologic origins to the materials shown on the logs and referenced within this report, based on: (1) a review of the background information and reference documents cited above, (2) visual classification of the various geologic material samples retrieved during the course of our subsurface exploration, (3) penetration resistance testing performed for the project, (4) laboratory test results, and (5) available common knowledge of the geologic processes and environments that have impacted the site and surrounding area in the past. D.3. Material Classification and Testing D.3.a. Visual and Manual Classification We visually and manually classified the geologic materials encountered based on ASTM D2488. When we performed laboratory classification tests, we used the results to classify the geologic materials in accordance with ASTM D2487. The Appendix includes a chart explaining the classification system we used. D.3.b. Laboratory Testing The exploration logs in the Appendix note the results of the laboratory tests performed on geologic material samples. We performed the tests in general accordance with ASTM procedures. D.4. Groundwater Measurements The drillers checked for groundwater while advancing the penetration test borings, and again after auger withdrawal. We then filled the boreholes or allowed them to remain open for an extended period of observation, as noted on the boring logs. City of Falcon Heights Project B2203417 June 13, 2022 Page 16 E. Qualifications E.1. Variations in Subsurface Conditions E.1.a. Material Strata We developed our evaluation, analyses and recommendations from a limited amount of site and subsurface information. It is not standard engineering practice to retrieve material samples from exploration locations continuously with depth. Therefore, we must infer strata boundaries and thicknesses to some extent. Strata boundaries may also be gradual transitions, and project planning should expect the strata to vary in depth, elevation and thickness, away from the exploration locations. Variations in subsurface conditions present between exploration locations may not be revealed until performing additional exploration work, or starting construction. If future activity for this project reveals any such variations, you should notify us so that we may reevaluate our recommendations. Such variations could increase construction costs, and we recommend including a contingency to accommodate them. E.1.b. Groundwater Levels We made groundwater measurements under the conditions reported herein and shown on the exploration logs, and interpreted in the text of this report. Note that the observation periods were relatively short, and project planning can expect groundwater levels to fluctuate in response to rainfall, flooding, irrigation, seasonal freezing and thawing, surface drainage modifications and other seasonal and annual factors. E.2. Continuity of Professional Responsibility E.2.a. Plan Review We based this report on a limited amount of information, and we made a number of assumptions to help us develop our recommendations. We should be retained to review the geotechnical aspects of the designs and specifications. This review will allow us to evaluate whether we anticipated the design correctly, if any design changes affect the validity of our recommendations, and if the design and specifications correctly interpret and implement our recommendations. City of Falcon Heights Project B2203417 June 13, 2022 Page 17 E.2.b. Construction Observations and Testing We recommend retaining us to perform the required observations and testing during construction as part of the ongoing geotechnical evaluation. This will allow us to correlate the subsurface conditions exposed during construction with those encountered by the borings and provide professional continuity from the design phase to the construction phase. If we do not perform observations and testing during construction, it becomes the responsibility of others to validate the assumption made during the preparation of this report and to accept the construction-related geotechnical engineer-of-record responsibilities. E.3. Use of Report This report is for the exclusive use of the addressed parties. Without written approval, we assume no responsibility to other parties regarding this report. Our evaluation, analyses and recommendations may not be appropriate for other parties or projects. E.4.

INFORMATION/ANNOUNCEMENTS: Council Member Leehy requests that when Jack Linehan, the City Administrator, gives his updates, that he includes clarification for those concerned about a passageway on Ruggles. Council Member Wehyee states that the Planning Commission will meet on October 25th. The Planning Commission has not met since September. Mayor Gustafson states that the Community Engagement Commission will be meeting Monday, October 17th, at 6:30 p.m.in the City Hall Chambers. The Commission will discuss Human Rights Day and update the new resident packet. The Park and Recreation Commission will have two new members. The City is still looking for someone from the community to step up for the St. Paul Water Board. More information on the St. Paul Water Board is on the City website. Or, give the Mayor a call to walk you through the process. Council Member Leehy asks if there is a deadline for the St. Paul Water Commission. Linehan states that Friday, October 14th is the deadline. The City has not received any applicants for the Commission. Council Member Leehy asks whether the notice describes the requirements for serving on that Commission. Linehan states that the description outlines the requirements. In addition, the St. Paul Water Commission meets monthly in person. The term ends December 31st, 2023, so it is about a 14-month commitment. Linehan states: • Public Works Street Sweeping o Public Works completed street sweeping of all Falcon Heights streets last week. Street sweeping will continue periodically throughout the fall until snow falls. o A reminder to residents: please do not rake leaves in to the street. The street sweeper cannot take that additional volume of leaves, and it is an ordinance violation.  Residents did a great job last week keeping leaves out of the street, which made the pass through the community smoother and without equipment clogging • iWorQ Permitting System o We are excited to announce the launch of our iWorQ public portal. o Residents and contractors can now apply for a wide range of permits entirely online, from fence permits to mechanical permits. o Residents can also search active permits and see a full list of open permits. That is public information. If residents were curious if there were active permits on a home they wished to purchase, they could see that. Or, if they saw a contractor working on a roof and were curious if they had a permit for it, they could look it up and check as well. o This new software will save staff time and improve service delivery to residents at a minimal cost. A review is still required and the timeline is two days to two weeks; we try to stay on the low end of that. o To view the iWorQ public portal and apply for permits, visit the www.falconheights.org, click on “I Want to” -> “Apply For” -> Permits. A button on the permitting page will take you to the iWorQ portal. • Falcon Woods 2025 PMP Neighborhood Meeting o Wednesday, October 19th at 6:30 PM in Council Chambers o The meeting will discuss the planned reconstruction of roads in Falcon Woods occurring in 2025 to give residents an early overview. • Ruggles Pathway Update o The city has been contacted by neighbors in the Northeast Quadrant concerned about the proposed Ruggles Pathway. o I want to clarify that no decision has been made, and Engineering is including various options in their feasibility report. o The Ruggles Pathway has long been identified by the City as a site that needs to be brought up to code to meet the requirements of the Americans with Disabilities Act. The current “goat path” does not meet federal requirements for wheel chair accessibility. o The next step in the process will be on Wednesday, October 26th at 7PM, when Engineering presents the 2023 PMP Feasibility Report to the City Council. o If the Council accepts the report, that will trigger a public hearing held on Wednesday, November 9th at 7PM. Notice of the public hearing will be sent to all residents impacted by the 2023 PMP by mail. o Residents are encouraged to attend the November 9th Public Hearing, as afterwards the City Council will make a final recommendation on the entirety of the 2023 PMP, including the Ruggles Pathway. • Amber Union Update o Certificate of Occupancy was issued for the main building on September 30th. o Some residents began moving in on October 1st. o The western annex building is aiming to have a Certificate of Occupancy issued at the end of October. o A ribbon cutting and open house for neighbors is being planned to coincide with the opening on the annex building in late October/early November. Dates and formal invites are still being worked out with the developer and property management company. • Council Vacancy o Following tonight’s declaration of vacancy, recruitment for Kay Andrews’ replacement for her term expiring December 31st, 2023 will begin on Thursday, October 13th. Applications will be made available on our website and in-person at City Hall. Applications will close on Wednesday, October 26th.

Description Falcon Heights established a Flexible Benefit Plan in October of 2007. That plan currently has a $2,500 maximum reimbursement limit for health care and a $5,000 maximum reimbursement limit for dependent care. It has been recommended by our Flexible Benefit Plan administrator that we amend the plan to provide for the maximum statutory reimbursement limit of $3,050 for the health flexible spending part of the plan. This increase is allowed by the Internal Revenue Code, and adjusted from time to time due to inflation. This amendment would allow for future statutory rate increases without us having to amend the plan. Currently, this IRS approved increase is only in the Health Care Flexible Spending part of the plan or in the Limited Health Care Reimbursement Account part of the plan. Dependent care would remain at the $5,000 level. Currently, city employees only use the Health Care Flexible Spending and dependent care parts of the plan. Budget Impact Estimated expenditure for this plan amendment is $250. Attachment(s) City of Falcon Heights Flexible Benefits Plan Amendment. Action(s) Requested Staff recommends approving the amendment for the city’s Flexible Benefits Plan to allow for the maximum statutory reimbursement limits allowed by the IRS.
