I 121 Cityoy r Louisville PARKS & RECREATION Memorandum To: Open Space Advisory Board Joliette Woodson, Public Works Engineering From: Allan Gill, PLA, and Park's Project Manager Date: March 13, 2018 Re: SH 42 Underpass, 60% Plan Review Attached for your reference are the landscape and architectural sheets from the 60% submittal dated February 21, 2018 which includes the trail alignment and three architectural elevation options. Pro's & Con's, Architectural Elevations: Pro's & Con's with regard to the architectural elevations are subjective. Elevations 'A' and `A.1', have a stronger vertical presence resembling the recently completed South Street Underpass while elevation `A.2', is more subtle and resembles the underpass near the intersection of McCaslin Boulevard and Washington Avenue. Park and Recreation Department Staff are in support of architectural elevation A.2 with its more subtle character and similarities to the underpass near the intersection of McCaslin Boulevard and Washington Avenue rather than options 'A' and `A.1' which are more vertical and prominent. The similarity in architectural character helps to promote consistency in design throughout the City. Staff recommendations are subject to review and comment by the Parks and Public Landscape Advisory board (Parks Board) and the Open Space Advisory Board (OSAB). OSAB concurs with staff recommendations on architectural option A.2 OSAB Comments: Kestrel Trail Extension: Yes No OSAB has already selected the curved option for the portion of trail on the west side of Hecla Drive. On the east side of Hecla Drive the City owns a parcel of land that is about 30' wide and 100' long. Initial conceptual trail alignments kept the trail on City property; however, the alignment was not desirable from a trail user's perspective. To achieve the desired trail alignment two steps are being proposed. The first is to construct a temporary alignment which includes two street crossings followed by the final alignment which would be constructed with development of the adjacent parcel to the north. This approach is recommended as the desired trail alignment is achieved and the cost of construction is reduced as it would occur with development. 13
