13. Traffic Circulation: The conceptual PD plan provides a total of 4 connections to a proposed extension of 53rd Street, and those include a primary full -movement connection, a right-in/right-out connection near the commercial area (east end), a gated, one-way egress connection at the midpoint of the project, and a stabilized emergency access connection at the far west end of the project (see attachment 5). The primary full -movement connection will be served by a westbound right -turn lane and an eastbound left -turn lane, and the right-in/right-out connection will be served by a westbound right -turn lane. The internal roadway system is designed as a modified grid system that provides internal access to the various components of the project, including several roundabouts. All internal streets are proposed to be privately maintained by and dedicated to a property owners' association. However, the public will have access to the limited commercial portion of the project site, and the hotel site. All access points and the internal circulation plan has been approved by Traffic Engineering and Fire Prevention. The dedication and improvements section of this report provides a list of traffic improvements required to be provided by the project, and those improvements have been determined based upon a traffic impact study submitted by the applicant and approved by Traffic Engineering. Responsibilities for and timing of required improvements and conditions may be outlined in further detail in a future Developer's Agreement. That agreement may include additional improvements and conditions, and must be approved by the Board of County Commissioners prior to preliminary PD plan approval for Phase I of the project. 14. Required Dedications and Improvements: a. Right -of -Way Dedication for 53rd Street: The County's Thoroughfare Plan classifies 53rd Street as an arterial roadway that requires 200' of ultimate right-of-way (ROW). However, the required ROW width may be reduced based on roadway design (i.e. curb and gutter) and roadway drainage being handled by the project's internal stormwater system. The developer has coordinated with Public Works, and has agreed to a roadway design that requires 150' of road ROW. That roadway design and ROW width is consistent with the current design and alignment of 53rd Street on the east side of 58th Avenue. Currently, 30' of road ROW exists along the project's entire 53rd Street frontage. Therefore, the developer has agreed to dedicate an additional 120' of ROW for 53rd Street along the project's entire 53rd Street frontage. It should be noted that a 120' ROW dedication has already been completed for the eastern ±1,290' of the project's 53rd Street frontage. That ROW dedication was coordinated between the current owner/developer, the previous owner, and the County, and was executed when the current owner/developer purchased the property. The ROW dedication for project's remaining ±2,000' of 53rd Street frontage must be completed prior to the issuance of an LDP for Phase 1 or as outlined in a future Developer's Agreement (if applicable). b. Roadway Paving for 53rd Street: Currently, 53rd Street is an unpaved dirt road west of 58th Avenue, and is a 4 -lane, "boulevard" style arterial road east of 58th Avenue. The developer is required to construct 53rd Street as a 4 -lane road from 58th Avenue to the project's primary driveway connection to 53rd Street, and then transition down to a 2 -lane road to the west end 111
