General Fund Cost Drivers General Fund Revenue Impacts Capital and Debt Levy Impacts THIS PAGE LEFT INTENTIONALLY BLANK MEMORANDUM To: St. Anthony Village City Council From: Shelly Rueckert, Finance Director and Charlie Yunker, City Manager Date: February 9, 2021 City Council Work Session Request: Proposal for Tennis Court Resurfacing Project Funding BACKGROUND The Tennis courts located south of City Hall were built in 1998 and have been repaired on four different occasions since 2012 and are in need of replacement. The courts are well-utilized by the general community as well as the school district for physical education classes and the tennis team. The 2021 Capital Improvement plan has scheduled the resurfacing of the tennis courts located next to City Hall as a 2022 project. Given the current conditions of the court City Staff has explored moving up the project date to 2021. This topic of project timing was discussed at the October 26, 2020 City Council Work Session and staff was directed to seek input from the Parks & Environmental Commission. The Commission discussed the topic at their December 7, 2020 meeting and supported moving the project to 2021 if a funding source could be identified. The project’s cost is estimated at $180,000, which comprises the contractors quote, engineering costs and a 5% contingency allowance. The project costs exceed the current Park Improvement Funds’ resources. Therefore, Staff is recommending the use of an Interfund Loan to finance the 2021 project costs. Given this size of an expenditure an Interfund Loan is a more cost effective and expedient tool than debt financing. Staff is also recommending phasing in a Parks Improvement levy over a 10-year horizon. The potential levy and Interfund loan terms have been structured to provide: • The repayment of the Interfund loan in 15 years • An additional source of funds for future Park Improvement expenditures • Interest earnings to internal lending source that exceeds the present investing rates DISCUSSION ITEMS FOR COUNCIL FEEDBACK Below are the specific items for discussion and feedback for the City Council: • Does the Council support the use of an Interfund Loan? • Does the Council support phasing in a Parks Improvement levy over a 10-year horizon? • Any other aspects of the replacement Staff should consider?

KLM Engineering, Inc. Proposal. b. General guidelines of AWWA Manual M42 Appendi c. KLM "Procedures and Guidelines for Inspecting Existing Steel and Concrete Water Storage Tanks." d. Appendix D Inspection and Evaluation Methods. 2.1|Structural Examination Summary Based on the inspection data, it appears that some miscellaneous structural modifications and repairs are required. These modifications and repairs serve to bring the tank into compliance with OSHA regulations and AWWA standards, allow for better coating bonding, allow for safer access in and on the tank and, in some cases, removing unnecessary items. 2.2|Coating Evaluation Summary 2.2.1|Lead and Chromium Content Analysis Due to the coatings, application date of ffect at that time limiting the use of lead or chromium based coatings, samples were not taken of the various types of coatings present on the interior and exterior surfaces for lead or chromium testing. 2.2.2|Interior Wet Coating Although records are not available, due to design it is presumed the tower was constructed and originally coated by Universal Tank and Iron Wo is badly corroded and illegible). The interior wet area was recoated by an unknown contractor in about 2000. There is visual evidence of spot repairs applied approximately within the last five (5) years. The interior wet coating is in good to fair condition with approximately ten (10) percent coating failures above and below the High-Water Line (HWL). Failures above the HWL consist of corrosion along unwelded roof plate weld seams and rust nodules at random locations. Failures below the HWL consist of rust nodules on weld seams, intermittently welded shell stiffener ring and random locations. Due to age and condition the coating is not a candidate for repairs and should be replaced in its entirety within three (3) years at the same time as the exterior coating. See photos in Appendix A. 2.2.3|Exterior Coating The exterior coating was replaced at the same time as the interior coating by Odland Protective Coatings in about 2000. The exterior coating is in fair to poor overall condition with approximately twenty (20) percent visible coating failures observed throughout the structure. The coating failures consist mainly of topcoat TOWER NUMBER ONE CITY OF ST. ANTHONY, MINNESOTA Copyright 2020 by KLM Engineering, Inc. Page 4 delamination primarily on the roof and bowl. Failures of this type will continue to occur due to age and normal deterioration exposing the underlying coatings to UV deterioration. Failures also include isolated pinhole corrosion, and typical coating damage on wear areas like handrails and ladders. The exterior should be recoated in three (3) years to maximize the life expectancy of the structure. See photos in Appendix A. It is more cost effective to remove the exterior and the interior coating at the same time. 3.0|RECOMMENDATIONS The photographs referred to in this section are in Appendix A. All drawings are found in Appendix B. The surface preparation requirements for all repairs as well as the requirements for welding are described in Appendix C. Based on an evaluation of the inspection data, the recommendations are: 3.1|Interior Wet Structural The following structural repairs are not required to be performed at this time and can be delayed until interior coating repairs are required. 3.1.1 Seal weld the following joints. Seal welding these joints will prevent rust streaking and corrosion in areas inaccessible to paint. In most cases the welding is to bring the interior area in compliance with AWWA D100-11. See photos 2 through 10. a. The overlap seam between the roof plates and the upper torus plates, b. The overlap joint between the dollar plate and the roof plates, c. The six (6) roof plate lap joints, d. Both sides of the intermittently welded upper shell course stiffener plate, e. The inside joint between the wet access manway and the dollar plate. 3.1.2 Add two (2) roof rafters, 1/2-inch by 8-inch bars, by 38-feet long spaced at 5-foot centers symmetrical around the finial vent to support a containment system when recoating the exterior of the tank. See photos 2 through 5. 3.1.3 Grind off all weld spatter and erection scab marks below the HWL. This will comply with AWWA D100-11. See photos 11 through 16. This work will require approximately 60 man-hours. 3.1.4 Replace the gasket on the 12 by 18-oval manway in the bottom of the wet riser. See photo 45. 3.1.5 Install a Grid-Bee GS-9 Submersible Mixer in the tower to provide mixing capabilities that reduce the likelihood and magnitude of ice formation in cold weather and prevent stratification in warm weather, improving water quality and reducing the necessity of chemical additives such as chlorine. Include the installation of all electrical components and control panel for proper operation through SCADA systems. Refer to KLM Drawing 61. 3.2|Interior Wet Coating 3.2.1 The interior wet coating is in good to fair condition with approximately ten (10) percent coating failures above and below the High-Water Line (HWL). Failures above the HWL consist of corrosion along unwelded roof plate weld seams and rust nodules at random locations. Failures below the HWL consist of rust nodules on weld seams, intermittently welded shell stiffener ring and random locations. See photos 2 through 20 TOWER NUMBER ONE CITY OF ST. ANTHONY, MINNESOTA Copyright 2020 by KLM Engineering, Inc. Page 5 3.2.2 After structural repairs are completed, all the reservoir surfaces should be abrasive blasted to an SSPC-SP-10 Near White Metal Blast and coated with a zinc/epoxy system (similar to the Tnemec Series 91- H20 Hydro-Zinc/Series N140 Pota-Pox Plus Epoxy coatings). 3.3|Cathodic Protection System (C.P.) 3.3.1 The reservoir does not have a Cathodic Protection system, and one is not required if the coating is applied and maintained properly. 3.4|Exterior Structural The following structural repairs are not required to be performed at this time and can be delayed until exterior coating repairs are required. 3.4.1 Remove both finial vents, patch the hole on the off-set 24-inch vent with a ¼-inch plate butt welded inside and out, grind all welds smooth. See photo 21. 3.4.2 Install a new finial vent with a 24-inch diameter aluminum pressure pallet style vent at the center of the tank, similar to the one shown on KLM Drawing No. 8a. See photo 21. The new vent and vent screen design should meet AWWA D100-11 and local Health Department Regulations. The removable top will improve ventilation, provide access to the tank interior during reconditioning, and aid in compliance with OSHA Confined Space Entry Requirements. 3.4.3 Remove and replace the handrail on both sides of the roof ladder and cross angles with an angle style handrail conforming to OSHA regulations. Remove the upper section of the roof ladder. The roof ladder is not required unless the roof slope exceeds a 5 in 12-inch slope. Install a non-skid walkway within the area of the hand railing. See photos 25 and 26 and reference KLM Drawing No. 14a. 3.4.4 Remove the approximately 32 pairs of containment tabs on the roof, grind all areas smooth and flush with the roof plates per Appendix C. See photos 24 through 26. 3.4.5 The existing balcony handrail does not meet OSHA requirement for a mid-rail/toe board, there are antenna braces causing trip hazards and access from the leg ladder to the balcony is difficult and unsafe. Replace the handrail in its entirety and provide an opening for the access ladder to grade meeting OSHA requirements. See photos 32, 33, 35 and 36 and KLM Drawing No. 27. 3.4.6 Replace all the exterior ladders not meeting current OSHA requirements for width and rail size with new OSHA compliant ladders complete with cable style 24 and photos 27, 35, 43 and 46. 3.4.7 Install a hinged, locking cover over the lower 8 feet of the ladder. This will restrict access by unauthorized personnel. Refer to photo 46 and KLM Drawing No. 20. 3.4.8 Install one (1) 24-inch diameter shell, pressure style manway in the bottom section of the wet riser, 180 degrees from the existing manway. This will improve the ventilation during reconditioning and bring the tank into compliance with OSHA Confined Space Entry requirements. See KLM Drawing No. 37a and photos 44 and 45. 3.4.9 Replace the existing overflow pipe screen with a corrosion-resistant, heavy-gauge #4 mesh screen, the existing is partially plugged. See photo 48. TOWER NUMBER ONE CITY OF ST. ANTHONY, MINNESOTA Copyright 2020 by KLM Engineering, Inc. Page 6 3.5|Exterior Coating 3.5.1 The exterior coating is in fair to poor overall condition with approximately twenty (20) percent visible coating failures observed throughout the structure. The coating failures consist mainly of topcoat delamination primarily on the roof and bowl. Failures of this type will continue to occur due to age and normal deterioration exposing the underlying coatings to UV deterioration. Failures also include isolated pinhole corrosion, and typical coating damage on wear areas like handrails and ladders. See photos 21 through 47. 3.5.2 After structural repairs are completed, all the reservoir surfaces should be abrasive blasted to an SSPC-SP-6 Commercial Blast Clean and coated with a zinc/epoxy/urethane/fluoropolymer system (similar to the Tnemec Series 91-H20 Hydro-Zinc/Series N140 Pota-Pox Plus Epoxy/Series 73 Endurashield/Series 701 Hydroflon coatings). 3.6|Site and Environmental Considerations 3.6.1 The site includes the tank and an antenna building enclosed in a chain link fence mowed grass site. The site is adjacent to a play area near the middle school. There is a fire hydrant on the site. 3.6.2 In conformance with Minnesota state rules, an analysis has been performed to determine the methods of pollution control required for this storage structure during reconditioning. To maintain air quality and to prevent the drift of dust and fugitive emissions, full containment will be required, including impervious ground cover, a top cover or bonnet and negative air dust collection. 3.7|Telecommunications Considerations 3.7.1 The tower has some telecommunications equipment, including antennas, coaxial cables, support brackets and other miscellaneous equipment. The Owner is advised to maintain accurate records of each of the antenna sites on the tower, including As-Built Drawings, site manager and owner contact information, upgrades performed, and future plans for antenna installations or upgrades. These records will help facilitate the future reconditioning with a minimal 3.7.2 Working around and protecting the telecommunications equipment, including antennas, coaxial cables, support brackets, and other miscellaneous equipment during future reconditioning will incur additional costs. The antenna owner(s) should be responsible for these expenses under clause(s) in the antenna lease agreements. These costs are not included in the Engineer tower to tower. 3.7.3 Prior to reconditioning, in accordance with the lease requirements of each antenna owner, the City of St. Anthony should notify the telecommunications owners or manager of the work to be performed. The City should also determine whether: a) the antenna owners will pay the additional costs to work around and protect the antennas; b) the antenna owners will temporarily remove their antennas and associated equipment to facilitate reconditioning; or c) the City will have to pay for these costs themselves. 4.0|REPAIR AND RECONDITIONING OVERVIEW 4.1|Repair and Reconditioning Cost Estimate The costs for structural repairs and replacing the interior and exterior coatings are estimated between $610,000 and $640,000. This estimate is based on current pricing and does not include costs for engineering and/or inspection services. For competitive bids, the project should be bid 9 to 12 months before the desired starting date. An experienced tank-coating contractor with the proper crew and equipment should be able to complete the project in eight (8) weeks. At the time of reconditioning, the tower will need to be drained and remain off-line during interior TOWER NUMBER ONE CITY OF ST. ANTHONY, MINNESOTA Copyright 2020 by KLM Engineering, Inc. Page 7 structural modifications, abrasive blasting, and painting. However, most of the exterior structural modifications can be performed prior to draining, with the tank in-service. On January 1, 2023, National Sanitary Foundation (NSF) will implement a new health requirement called NSF 600 which will require all coatings in contact with potable water to meet new, lower extraction levels. These new limits may restrict available product offerings and qualified applicators resulting in increased overall reconditioning costs. The costs for applying a coating system, that complies with the new regulation, to the interior wet area is not included in the provided cost estimate. 4.2|Remaining Tank Life Based on the inspection data, if the recommended structural repairs and coating replacement are completed within the next three (3) years, the tank will be satisfactory for continued service provided that it is inspected and maintained regularly. The tank and coating should first be inspected within the warranty period and every three (3) to five (5) years thereafter. New interior and exterior coatings, if applied and maintained properly, should last at least 20 years. KLM ENGINEERING, INC. Report prepared by: Jerry J. Tell, P.E.
