The majority of the drainage for the area west of Center Street currently flows north from Sunwood Drive to the vacant parcels, wetlands, and depressions west of Center Street. The storm water then infiltrates or flows overland to an outlet pipe near the Sunwood Drive and Yolite Street intersection. The Veterans Drive and Peridot Street extension area currently drains to the existing wet pond located at the southeast corner of The COR. The existing wet pond and infiltration basin are shown in Figures 6 and 7 in Appendix B. Wetlands In the fall of 2022, a wetland delineation was conducted within The COR Study area. Those findings are still under review at the LRRWMO. Wetland delineations are depicted in Figures 6 and 7, and the full delineation report is included in Appendix D. Mitigation will be required for a portion of the existing wetlands if they are impacted by development. /III IR AIII;;)''//4/' Y LASSO IIF III AT III NS AINIID IIDIII SIIIGIN ' IN IIIIIDIII IIRATIII IN This analysis includes examining the feasibility of constructing roadways and other supporting public infrastructure in The COR. Roadways included in the study are as follows: • Ramsey Parkway — Willemite Street NW to Sunwood Drive NW, • Center Street NW - from the existing developed section north to Bunker Lake Boulevard, • Zeolite Street NW — from Sunwood Drive to Bunker Lake Boulevard, • Yolite Street NW - Sunwood Drive to Ramsey Parkway, • Veterans Drive NW - Rhinestone Street to Ramsey Boulevard, and • Peridot Street NW - Sunwood Drive to Veterans Drive. Figures 1 and 2 in Appendix B depict the roadway segments and geometrics included in this analysis. Street Hierarchy The COR Design Framework plan establishes a street hierarchy designation for roadways within The COR (see Appendix A). The 2040 Comprehensive Plan establishes road classifications to create a safe and efficient roadway network throughout the City (see Appendix A). The following table presents a summary of roadway classifications.
