LCity; <br />Louisville <br />PARKS & RECREATION <br />Memorandum <br />To: Joliette Woodson, Public Works Engineering <br />From: Allan Gill, PLA, and Park's Project Manager <br />Date: March, 2018 <br />Re: SH 42 Underpass, 60% Plan Review <br />Attached for your reference are the landscape and architectural sheets from the 60% submittal dated <br />February 21, 2018 which includes three options for plant material and three architectural elevation <br />options. <br />Plant Material: <br />Option 'A' includes native seeding over most of the area with accent native seeding adjacent to <br />sandstone slab's set on edge with crushed stone mulch as a focal piece. <br />Option B' includes native seeding over most of the area and includes trees and shrubs in a planting <br />bed as a focal point. <br />Pro's & Con's Plant Material: <br />Plant Material Option 'A' <br />Pro's, low maintenance and less water consumption. <br />Con's, without plant material the underpass does not resemble the underpasses at McCaslin <br />Avenue and South Street which both have plantings and share stronger design. The <br />underpasses on Cherry Street near the golf course and South Boulder Road west of <br />Washington Avenue do not have plant material. <br />Plant Material Option B' <br />Pro's, adding trees and shrubs strengthens the landscape character and more closely <br />resembles the underpasses at McCaslin Avenue and South Street providing consistency with <br />regard to design. <br />Con's, more maintenance and more water consumption. <br />Pro's & Con's, Architectural Elevations: <br />Pro's & Con's with regard to the architectural elevations are subjective. Elevations 'A' and `A.1', <br />have a stronger vertical presence resembling the recently completed South Street Underpass <br />while elevation `A.2', is more subtle and resembles the underpass near the intersection of <br />McCaslin Boulevard and Washington Avenue. <br />With the expected high use by the public, Park and Recreation Department staff are suggesting a <br />hybrid approach to plant material which includes native grass, trees and `randomly' placed boulders <br />and omits the planting area, shrubs and sandstone placed on edge. This option keeps maintenance <br />
