LCity,f Louisville Parks & Recreation Memorandum To: Parks and Public Landscaping Advisory Board (PPLAB) From: Allan Gill, PLA, Parks Project Manager Date: May 2, 2019 Subject: Kickoff Meeting with Colorado Designscapes and Design Concepts as Part of the Median Landscape Renovations, Capital Improvement Project (CIP) Purpose: The purpose of this agenda item is to introduce the design -build team to the board, to review and discuss ideas and provide general direction for the design -build team regarding the various corridors moving forward. Initial discussion regarding the emerald ash borer (EAB) and ash tree mitigation and irrigation will also be part of this discussion. Background: The majority of medians within the City were developed and landscaped 20 to 30 years ago. Renovations are recommended due to, outdated irrigation systems, plant material replacement needs, and in many cases, the concept or landscape theme is not consistent throughout the same boulevard. The following boulevards with medians on them will make up the design -build team's scope: • Cherry Street • Dillon Road • Via Appia • McCaslin Boulevard • South Boulder Road • Additional medians identified by PPLAB and staff as needing renovation are listed below and will be part of the project. o Summit View Drive and Hwy. 42, 1 small median o Dillon Road and South 88th Street, 1 long median Prior to acquiring funding for median renovations, the City worked with a consultant to develop preferred options for the medians. As part of that effort, the consultant prepared possible plant palettes, design aesthetics, gateway and identity features, ground plane treatments and conducted a visual preference study all of which will be shared with the design -build team moving forward. In review of the final report staff and PPLAB ultimately choose to work with current designs and enhancing and repairing the medians as needed rather than following the preferred options prepared by the consultant. Some of the factors that staff and PPLAB took into consideration when comparing concepts were costs, maintenance practices, herbicide use, tree replacement, visibility among other issues. Next Steps: Allow the design -build team to begin working on the project, formalize a project schedule, develop initial concepts for review and discussion during a 30% design review meeting with PPLAB in conjunction with a public open house to gather input from the board and the public. 5
