Director Public Works Department CITY OF MIAMI, FLORIDA INTER -OFFICE MEMORANDUM DATE : SUBJECT: 2006 J N v January 25, 2006 PM2:6 Large Scale Development Review - 2121 Biscayne Boulevard REFERENCES: ENCLOSURES: The Public Works Department has reviewed the Large Scale Development plans for the development entitled 2121 Biscayne Boulevard and has the following comments. 1. A 25 foot corner radius dedication is required at the intersections of the base building lines at N.E. 215t Street with Biscayne Boulevard. The proposed stairs are not permitted to encroach beyond the 25 foot corner radius. 2. The proposed structure and stairs encroach into the required corner visibility triangle at the corner of Biscayne Boulevard and N.E. 21st Street. The Lobby level at 3 ft. above grade is not permitted to encroach into the 25 ft. visibility triangle. 3. All transitions from the established street profile grade to the building floor elevation must be accomplished on private property. Stairs, ramps, retaining walls, etc. will not be permitted in the public right of way and the record profile street grade can not be changed to accommodate the proposed building ground floor elevation. 4. All stormwater must be retained on site including the driveways, interior courtyards and plazas on private property adjacent to the public streets. All common areas, plazas and driveways must be graded or trench drains provided to prevent "sheet flow" from entering the right of way. If deep drainage wells are selected for stormwater disposal, they must be located on -site in an open area to accommodate future maintenance access. 5. An agreement between the City of Miami and the property owner is required for any landscaping and decorative sidewalk treatment located in the public right of way. Public Works approval and permit is required for any landscaping improvements in the right of way. A F.D.O.T. permit is required for improvements along Biscayne Boulevard. 6. Standard parking spaces are 8.5 feet wide and 18 feet long and require a 23 foot back-up distance. A Special Permit is required to reduce the back-up distance and for backing into the loading stall from the right of way. Ana Gelabert-Sanchez Director Planning Department Page 2 January 25, 2006 7. The maximum driveway approach width is 40 feet. City of Miami driveway entrances, in compliance with A.D.A. standards, shall be required. Continuous sidewalk is required across driveway entrances. 8. Public Works policy requires that no closures of vehicular travel lanes will be permitted during the course of construction unless a temporary replacement lane, approved by the Public Works Department, is constructed and maintained by the Contractor throughout the duration of the lane closure. A maintenance of traffic plan is required for any temporary right of way closure request. 9. In order to mitigate traffic congestion and problems associated with unregulated parking throughout the neighborhood, the Contractor/Developer shall be required to provide approved, designated off -site parking for workers and a shuttle service to the work site. The parking/shuttle plan shall be coordinated with the local City of Miami NET Service Center. 10. Since this project is less than one acre in total construction area a Florida Department of Environmental Protection (DEP) Stormwater, Erosion and Sediment permit is not required. However, the methods of construction must comply with the City of Miami Municipal Separate Storm Sewer Permit (MS4). For information concerning these requirements, please contact our department at (305) 416-1200. In addition to these comments, the Public Works Department will require the following street improvements: N.E. 215t Street: Construct new concrete sidewalk, curb and gutter along the 25' required corner radius. Replace all broken sidewalk, curb and gutter on both sides of the street adjacent to the project site. Mill and resurface the entire width, curb to curb, adjacent to the project site. Coordinate improvements with the "Paramount" development. Biscayne Boulevard: Construct new sidewalk at the corner with N.E. 21 Street in order to comply with the 25 foot corner radius dedication requirement. Coordinate with the Florida Department of Transportation for replacement of all broken and damaged sidewalk and curb and gutter adjacent to the project site. Please contact the City's Planning Department and the City's CIP/Transportation Department for any Burle Marx Decorative Sidewalk implementation requirements. In addition, pavement restoration for all water and sewer extensions, existing damaged pavement and pavement damaged during construction, as determined by the City inspector, shall include milling and resurfacing of the full pavement width, curb to curb, along the entire length of the excavation and/or damaged pavement area. A thorough cleaning of all stormwater drainage inlets and storm sewer pipes adjacent to the building site shall be required at the completion of the project.
