characteristics of trees meeting the size requirements of the ordinance The tree inventory species and quantity are depicted in Figure 14 and tabulated in Appendix B. Due to the nature of the mass site grading anticipated within all of the undeveloped land at The COR, deep excavations and large earth fills, it is expected that all trees inventoried will need to be removed. City ordinances includes removal thresholds and requires 125% replacement of significant trees, with some exceptions to dedicated public rights -of - way and invasive tree species. Invasive species documented within The COR area include Siberian Elm. Street Lighting Street lighting will be in conformance with The COR Design Framework's Master Streetlight Plan. The costs included for street lighting assumes the light units will be owned, operated, maintained, and installed with City appropriated funds. Costs include conduit, wiring and the actual light fixtures to be installed. The density of the lighting fixtures is similar to the level provided along Riverdale Drive, east of Armstrong Boulevard. Trails/Sidewalks Trails were previously constructed along the center of the Ramsey Parkway median east of Center Street. A bioretention basin was constructed within the center median of Ramsey Parkway from Center Street to Willemite Street and is proposed to continue from Willemite Street to Sunwood Drive. 6-foot concrete walk is proposed on the north and south side of Ramsey Parkway to extend the pedestrian facilities to the west. A 10-foot concrete sidewalk is proposed along the west side of Center Street. All other roadways are proposed to include a 6-foot concrete sidewalk on either side of the road segment. Figures 15-17 in Appendix B show these typical sections. Landscaping The base project includes a very utilitarian approach to landscaping for the area. Pedestrian paths, trees and lighting were included, but other features, such shrubs, decorative features and monuments are not included in the estimated project costs. Developers will be responsible to construct boulevard landscaping improvements consistent with the City's zoning code. The exception to this is Sunwood Drive NW, where the boulevard costs include continuing the landscaping along the north side of Sunwood Drive as it exists east of Sapphire Street. The Ramsey Parkway median is being developed as a filtration median, with plantings typical for bioretention basins. Right -of -Way Requirements The COR was originally platted as Ramsey Town Center in 2003, with roadway rights -of -way (ROW) being established over a portion of the area. Future improvements within The COR will be primarily development driven, and ROW secured through the platting process. Understanding and documenting potential ROW needs will allow the City to plan in advance for acquisitions. Additionally, currently platted ROW can be vacated during the development process, allowing for larger areas of development. Figure 4 shows the existing ROW that does not follow the current master plan roadway alignments, and also shows new ROW required for future public improvements. The ROW depicted on the exhibits takes into account the width required for streets, boulevards, sidewalks, etc. as depicted in The COR Design Framework plan. Prepared by: Bolton & Menk, Inc.
