Flooding and drainage problems have been observed at. • Helena Avenue 81 17t" Street • Nederland Avenue 81 14t, Street • Nederland Avenue SL 1St" Street • Ek>stcm Avenue 8, 15— Street • C>etroit ^\,enue, 8t 1411 !Street • E>etrc:)it Avenue 8t 15th Street. ^ total of 9 proposed alternatives were considered. Steve Hamilton, Public Works C>irec-tc)" stated Alternative *g will be what staff is Prepared to recornrnerkcl. Alternative #S' will not increase the size of pipes along Nederland Avenue as it will mitigate approximately 30cfss of flow burden from existing storm sewer system at East Nederland 00rainage, System and reduce flooding pr<>tAerns at those areas. An estimated construction Cost for this improvement is approximately $800,000.00. Rick Bourque with Schaumburg 8, Polk, Inc. gave a report on the Nederland Avenue Street Rehabilitation Study- He explained the study is broken into 2 sectic>ns. Section I is frc>rn Highway 69 to 24— Street and Section 2 is from 2411 !Street to Twin City Highway. Section I has edge drainage, Concrete pavement with asphalt overlay and r,nc>cJerat,e business density. Section 2 has curb SL gutter drainage, concrete pavement with asphalt overly, high business density, and s(:,rne pedestrian accommodation. The elements considered for the study were: pavement, drainage, driveway Minutes Continued, April 18, 2016 improvements, underground utilities, access management and pedestrian accommodation. Pavement alternatives considered were: full replacement, and overlays- concrete and asphalt. Full Street Reo|acennentwith Base[)oUon: Cost ofOption /\ with Lime Treated Subgrade: Section 1: $2.71 Million Section 2: $3.22 Million Cost ofOption Bwith Crushed Concrete Base: Section 1: $3.15 Million Section 2: $3.67 Million Asohalt Overlav Option: Cost ofOption C: Asphalt Overlay Section 1: $2.52 Million Section 2: $2.82 Million Concrete Overlay: This alternative was eliminated from consideration due to insufficient geometry for required thickness, no experienced contractors inthis area, and maintenance requirement. Mr. Bourque advised there are several issues to consider when deciding on which alternative to select: expected service life, maintenance costs, and aesthetics. Full replacement has a ||he expectancy of approximately 20-35 years, and asphalt overlay has life expectancy of approximately 10 years. Drainage within this study addressed collection of surface run-off: edge drainage, curb 8kgutter. The conveyance system is addressed in a separate report from Action Civil Engineering. The edge drainage |s largely present in Section 1 and generally in good condition with some minor repairs needed' Curb hkgutter drainage is largely present inSection 2and functions poorly with significant ponding. Improvements toCollection: Edge Drainage Improvements inSection 1: Repair to damaged swa|eoand inlets asneeded -$O'1DMillion Curb bkGutter Replacement inSection 2: Completely remove existing curb &gutter, replace with curb & gutter at proper elevation and grade (included inpavement coSts),and replace orrepair inlets asneeded -$O.5OMillion Driveway improvements maintain a smooth drive to street transition, modify drainage to direct storm water to proper path, and improve aesthetics and safety through access management. Driveway Improvements: Section 1 Overlay -$O.1OMillion Section 1 Rap|acernent- $0.56 Million Section 2Overlay -$O.62 Million Minutes Continued, April 18, 2016 Underground Utilities included city owned underground utilities: water, wastewater, and storm; and privately owned underground utilities: natural gas, and telephone duct bank. City owned water lines are more than 50 years old and constructed of asbestos cement and cost iron. Existing wastewater lines include parallel lines and street crossings. Approximately 1/3rdofthese lines have been previously rehabilitated. Replacement or rehabilitation of original lines should be considered as they are nearing the end of the expected lifetime. Underground Utility Improvements: Replacement Section 1: $1.21 Million Replacement Section 2: $1.48 Million Access management is the control of driveway width, spacing, and proximity to each other intersecting streets for safety and improved aesthetics along the transportation corridor. Implementation is limited due to existing private parking conditions. Access Management Improvements: Section 1: $0.42 Million Section 2: $0.07 Million Pedestrian Sidewalks are predominately on one ykje in Section 2. They are frequently interrupted by driveways and not compliant with all ADA guidelines. Pedestrian Improvement: Section 1: Not Applicable Section 2: $0.28 Million Project Cost Summary for Section 1: New Pavement with lime base - $6.7 Million New Pavement with concrete base- $7.2 Million Asphalt Overlay - $5.9 Million Project Cost Summary for Section 2: New Pavement with lime base- $0'5 Million New Pavemmantwithconcnatebase- $9.1 Million Asphalt Overlay -$8.OMillion Mr. Bourque explained this will be a slow process due to the amount of businesses and maintaining their entrances with base material. He said there are several items to consider for the implementation process: the available budget, phasing to meet the budget if necessary, prioritizing of the elements, collection of information to confirm final design and selected options, utility conditions, confirming final drainage approach, review by contractor for risks and costs including length of time to perform work and extent ofdisruption during construction.
