(estimated cost - $940,000 for 2018-19 construction, $4,200,00, plus inflation costs, in the future) City of� Oshkosh MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: James Rabe, Director of Public Works /v— DATE: February 22, 2018 RE: Provide Direction to Staff Relating to Oshkosh Avenue Corridor Improvements (Oshkosh Avenue, Koeller Street, and Westfield Street) BACKGROUND In December 2017, the City executed an agreement with KL Engineering, Inc. (KL) of Madison to conduct a Traffic Impact Analysis (TIA) for the Oshkosh Avenue Corridor from Koeller Street to the Fox River. This TIA was driven by the changes in traffic patterns and trip generations related to the construction of the Oshkosh Corporation Global Headquarters and the planned redevelopment of the north side of Oshkosh Avenue from Koeller Street to Mary Jewell Park. KL conducted traffic counts within the corridor and consulted with the East Central Wisconsin Regional Planning Commission for background traffic data and future traffic forecast information. The goal of the TIA was to develop recommendations to continue to meet at least a Level of Service (LOS) of C or better in the "design year" of 2045. An LOS of A is the best you can have, while an LOS of F is completely failed, with varying degrees of functionality in between. On January 301h, a joint workshop between the Common Council, the Plan Commission, and the Traffic Review Advisory Board was held to allow KL to present the TIA background information, alternatives reviewed, and recommendations. The Traffic Review Advisory Board discussed the recommendations at their February 131h meeting and made a recommendation for the implementation of the results of the TIA. A Public Input Meeting was held at the Plan Commission meeting on February 201h to discuss the recommendations, take public input, and make a recommendation on the implementation of the results of the TIA. Staff is seeking direction from the Common Council on the implementation of the improvements for the Oshkosh Avenue Corridor, the North Koeller Street intersection, and the North Westfield Street intersection at this time. Direction is necessary at this time in order to appropriately design necessary infrastructure improvements to support the development of the Oshkosh Corporation Global Headquarters and the redevelopment of the properties along the north side of Oshkosh Avenue between North Koeller Street and Mary Jewell Park. Design of the infrastructure improvements cannot be done without direction as to what improvements are to be completed at this time. L\ Engineering \ 2018 CONTRACTS \ 18-14 Oshkosh Ave Area \ Project_Information \ Correspondence \ Memo \ 18- Page 1 Of 5 14 CC Memo -Direction Corridor Options_2-22-18.docx Among the assumptions made in the development of the TIF Plans for TIF 34 and 35, the following infrastructure assumptions were included: • Development of an additional right -turn only lane for the southbound approach to the North Koeller Street intersection, including additional right-of-way from 1870 Oshkosh Avenue. • Dedicated left -turn lanes on Oshkosh Avenue at North Westfield Street, including additional right- of-way from the properties between 1746 Oshkosh Avenue and 1610 Oshkosh Avenue, inclusive. • Additional street lights and streetscaping along Oshkosh Avenue in the area between North Koeller Street and Mary Jewell Park. The streetscaping improvements included grass terraces and terrace trees where feasible. ANALYSIS North Koeller Street Intersection: The two (2) alternatives developed this intersection are: (a) keep the intersection as is; or (b) develop the additional right -turn lane on the southbound approach. In order to provide the desired LOS in the future condition, the alternate that includes the addition of the dedicated southbound right -turn lane is recommended. North Westfield Street Intersection: The two (2) alternatives developed for this intersection are: (a) a four - legged signalized intersection; or (b) a roundabout. In order to provide the desired LOS, provide more reasonable pedestrian and bicycle crossing accommodations, and minimize the impact of additional right- of-way, the four -legged signalized intersection is recommended. Oshkosh Avenue Corridor: The analysis indicates the existing corridor cross section could function, albeit at a reduced LOS, for the developments with no improvements for the short term. In order to meet the LOS goals in the long term, improvements will be necessary. At a minimum, the development of the left -turn lanes at the North Westfield Street intersection are necessary in order to meet the desired LOS for the study period. The TIF Plan assumptions included the development of these left -turn lanes. Implementing additional improvements to the corridor will provide improved LOS and could provide improved aesthetics to this gateway corridor. The corridor alternatives realistically break down into five (5) different options: Option A: • Leave the corridor "as is", being a four -lane undivided cross section, with no left -turn lanes at North Westfield Street and the sidewalk remaining at the back of curb for the entire length of the corridor. Option B: • Implement the four -lane undivided cross section throughout the corridor with the development of the dedicated left -turn lanes at the North Westfield Street intersection. This option is Alternate 1 in the TIA. L\Engineering\2018 CONTRACTS\18-14 Oshkosh Ave Area\Project_1mormation\ Correspondence\ Memo\ 18- Page 2 Of 5 14 CC Memo -Direction Corridor Options_2-22-18.docu Option C: • Implementation of the four -lane divided cross section from North Koeller Street to North Eagle Street and the four -lane undivided cross section from North Eagle Street to the Fox River. This option is Alternate 1 from North Eagle to the Fox River and Alternate 3 from North Koeller Street to North Eagle Street in the TIA. This is the corridor recommendation from KL. Option D: • Implementation of the Two -Way Twin Left -Turn Lane (TWLTL) alternative. This option is Alternate 2 in the TIA. Option E: • A combination of Options B and C for implementation purposes. • Short-term implementation of the four -lane undivided cross section throughout the corridor with the development of the dedicated left -turn lanes at the North Westfield Street intersection. • Long-term implementation of the four -lane divided cross section from North Koeller Street to North Eagle Street and the four -lane undivided cross section from North Eagle Street to the Fox River. This is the corridor recommendation from KL. FISCAL IMPACT Option A: Costs would be for signal system upgrades at the intersection of North Westfield Street to allow for the addition of the fourth leg. This option is estimated to cost approximately $200,000. This amount is included in the TIF 34 and 35 budget assumptions. Option B: Costs are the "Base Model" costs, as presented in the development of the TIF Plans for TIF 34 and 35. This "Base Model" cost is estimated at approximately $940,000. Option C: Costs assume the complete reconstruction of Oshkosh Avenue from North Koeller Street to North Eagle Street in order to provide a uniform -looking design to the gateway corridor. Based upon that assumption, this option is estimated to cost approximately $4,200,000. This amount is $3,260,000 more than shown in the TIF 34 and 35 assumptions. A complete reconstruction would involve special assessments to adjacent properties along Oshkosh Avenue (including the residential properties on the south side) that could offset some of the unbudgeted costs. Per the City's Special Assessment Policy, staff conservatively estimate that special assessments would recoup approximately $400,000 of the street reconstruction cost. Additional assessments for items such as sidewalk rehabilitation, driveway aprons, and utility laterals would apply per the City's Special Assessment Policy. The entire $4,200,000 would still have to be financed through borrowing (General Obligation and Revenue for the Utilities), which may be recouped by TIF proceeds as development occurs in future years. Option D: Costs assume the complete reconstruction of Oshkosh Avenue from North Koeller Street to North Eagle Street in order to provide a uniform -looking design to the gateway corridor. Based upon that assumption, this option is estimated to cost approximately $4,000,000 for the TWLTL option. The cost of the additional concrete installation (in place of the vegetated median included in Option C) is offset by cost reductions in streetscaping features from within the vegetated island. The streetscaping features included a concrete curb and brick treatment similar to the median on STH 44 (South Park Avenue) just east of Koeller 1:\ Engineering \ 2018 CONTRACTS \ 18-14 Oshkosh Ave Area \ Project_Wormation \ Correspondence \ Memo \ 18- Page 3 Of 5 14 CC Memo -Direction Corridor Options_2-22-18.docx Street. This amount is $3,060,000 more than shown in the TIF 34 and 35 assumptions. A complete reconstruction would involve special assessments to adjacent properties along Oshkosh Avenue (including the residential properties on the south side) that could offset some of the unbudgeted costs. Per the City's Special Assessment Policy, staff conservatively estimate that special assessments would recoup approximately $400,000 of the street reconstruction cost. Additional assessments for items such as sidewalk rehabilitation, driveway aprons, and utility laterals would apply per the City's Special Assessment Policy. The entire $4,000,000 would still have to be financed through borrowing (General Obligation and Revenue for the Utilities), which may be recouped by TIF proceeds as development occurs in future years. Option E: Costs would be approximately $940,000 in the short term, and then $4,200,000 (not factoring in inflationary costs to the year the long-term implementation is built) in the future. This is the overall highest cost option due to implementing two (2) different options (Option B and Option C) over time. The Council could choose to implement the long-term portion of this plan when it is deemed financially feasible, or when Oshkosh Avenue requires reconstruction due to condition. RECOMMENDATIONS KL recommends the following implementation: • Addition of southbound dedicated right -turn lane at the North Koeller Street intersection (Alternate 1). • Development of left -turn lanes at the North Westfield Street intersection (Alternate 1). • Development of either a ninety -degree four -legged intersection (Alternate 2A) or a skewed four - legged intersection (Alternate 2C) at the North Sawyer Street Intersection. • Development of a four -lane divided cross section on Oshkosh Avenue from North Koeller Street to North Eagle Street (Alternate 3). • Development of a four -lane undivided cross section on Oshkosh Avenue from North Eagle Street to the Fox River (Alternate 1). The Traffic Review Advisory Board recommended Alternate 2A for the North Sawyer Street intersection, and concurred with the remainder of KL's recommendations. The Plan Commission recommended following KL's recommendations as written. Staff recommends accepting the recommendations from KL for the North Koeller Street and North Westfield Street intersections. Staff recommends delaying a decision on the North Sawyer Street intersection at this time to allow the Redevelopment Authority time to review the analysis and recommendations. Staff recommends corridor Option E presented above. This results in the best long-term LOS, while recognizing the financial realities and constraints of the current time.
