I *Revised Landscape Plan The revised landscape plan does not significantly differ from the previously approved plan (all phases). Like the approved plan, the revised plan: accents and ties into the pattern of existing natural and planted vegetation, lines the interchange ramps with trees, provides mass plantings within the I-95 median, and provides sod for roadway edges to provide a clean look along roadway shoulders. However, the revised plan goes further than the approved plan, by providing the following additions: 1. Expanding the original project area along SR 60 625' farther east and 30V farther west. 2. Providing special landscaping and irrigation within the SR 60 median (a curbed median is now proposed) throughout the interchange area, approximately 1,000 feet east and 1,000 feet _ west of the I-95 overpass. 3. Providing stamped, colored concrete hardscape features (in lieu of regular concrete) within SR 60 median areas. 4. Providing simulated stone wall (made from pour concrete) planter terraces in lieu of regular concrete slopes on the north and south sides of the overpass. Each terrace (three on each slope) will be landscaped with low maintenance plantings such as jasmine, firecracker plant, and bougainvillea. 5. Providing asphalt or stamped concrete shoulders underneath the overpass. Such improvements would clean-up the sandy "no man's land" where trucks and vehicles now tend to pull off and tear up the existing shoulder area. As of the date of this report, staff is working with MOT on finalizing an installation budget, which will range from $600,000 to a little over $800,000. Some changes in sod type (Bahia vs. St Augustine) and corresponding irrigation coverage, and tree size at the time of planting, may be adjusted to make FDOT's budget An itemized initial budget of $811,900 (Scenario "A") and a revised budget of $632,900 (Scenario "B") can be found in attachment Q. It is likely that Scenario "B" is what MOT will accept In that instance, irrigation and St Augustine sod will be used within the SR 60 median only. FDOT's consultants have provided maintenance estimate information that does not include annual tree trimming, or factoring in replacement costs on an annualized basis. Based upon the consultant's experience with and knowledge of other publically maintained landscape areas and interchanges, the consultant agrees with county staff that an estimate of $24,000 per year should cover all maintenance and annualized replacement costs associated with the proposed plan. Staff estimated that maintenance of the previously approved landscape plan improvements would also be about $24,000 per yam - Staff recommends that the Board of County Commissioners: 1. Approve the revised conceptual landscape plan, and 2. Authorize the chairman to execute the modified cash deposit and escrow agreement JUNE 2,1998 0 -76-
