2, CORRIDOR PLAN DESIGN OBJECTIVES Overall design objectives for this segment of 1-25 should respond to the following criteria: . minimize water use to 10"-12" per year by using Xeriscape principles and techniques, . minimize maintenance requirements by reduc- tion of turf areas through use 01 plant beds, groundcovers, wildllowers and creative use of areas of full height grasses, . enhance existing plantings along roadside. . provide seasonal color with wildllowers, conl- fe,s and deciduous plantings. . reinlorce urban identity and image through for- mallandscape treatments, . reinlorce regional character by utilizing native species in natural groupings, . . encourage adjacent property owners to Improve their properties to lurther complement the COrrI- dor beautilication, . unify the corridor with plants from a common plant palette . plant selection from a plant paleue consisting of plants ranked as moderate, low and very low for water requirements on the xeriscape scale. CORRIDOR "IMAGE" The Task Force agreed that a regional Colorado Im- age should be reflected in the study corridor's landscaping, rellected by the use 01 as many na- tive and naturalized plant species as possible, Dis- cussions regarding the type of landscaping ap- proach to be used centered on a balance between an natural, more informal landscape and an urban, more formal boulevard type of landscape, The ur- ban landscape approach, a linear treatment whh sharply defined edges, could be used to emp,ha- size some of the 'Gateway' Interchanges Into Downtown Denver, The natural approach, utilizing clusters and masses of plant materlaf and softer edges, would be applied along the corridor ~here the Pia lie River is adjacent. However, straight , formal rows of plant malerlal should be used only in Gateway statements or in restricted spaces, The intermixing of the two approaches will seIVe to em- phasize Denve(s close ass?ciation with the ~Ialle River, provide an opportunily for the reflectlO~ of this area's unique regional character, and hl9h- light urban area access. MASTER PLAN The master plan for the '-25 corridor was devel- oped to Identify areas which receive ehher,the nat- ural or urban fandscape treatments. Areas to re- ceive the urban treatments generally lie south of 1-70 to the Colfax Avenue interchange. Areas to receive the natural landscape treatments general- ly lie south of Colfax Avenue through the Broad- way/Lincoln interchange. Areas near the PlaUe River are to be landscaped in a more natural treat- ment to complement the river's character. Inter- changes and some roadway segments near Speer Boulevard should be landscaped to create a more formal urban treatment to reflect the urban image of Denver. This corridor plan will be used as a framework from which to develop more detailed landscape plans when portions of 1-25 are being rebuilt or when separate landscape projects are funded by CDOH, private developers, etc, .
