Director Public Works Department CITY OF MIAMI, FLORIDA INTER -OFFICE MEMORANDtM, DATE : SUBJECT: DeeriiI5 `2 ; 20Q5.' FILE : Large Scale Development Review - 600 Brickell REFERENCES: ENCLOSURES: The Public Works Department has reviewed the Large Scale Development plans for the development entitled 600 Brickell located at S.E. 7 Street and Brickell Avenue and has the following comments. 1. A 25 foot corner radius dedication is required at the intersections of the base building lines at S.E. 6 Street with Brickell Avenue. 2. The record profile grade for S.E. 6 Street slopes from 10.3 feet of elevation at Brickell Avenue to 8.6 feet of elevation at S.E. 1 Avenue. 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. 3. The maximum slope for a driveway ramp sloping downward toward the street is 1:10 for the last 20 feet to the property line. The maximum slope for a driveway ramp sloping upward toward the street is 1:20 for the last 20 feet to the property line. 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. 4. 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. An FDOT permit is required for all work in the Brickell Avenue and S.E. 7 Street right of way. 5. The sidewalks along S.E. 6 Street and S.E. 7 Street are too narrow to accommodate street trees in the right of way. Continuous pedestrian sidewalk is required within the public right of way abutting the project site without requiring pedestrians to enter private property. The sidewalk width must maintain 5 feet in order to comply with A.D.A. clearance requirements. The proposed trees along these streets must be located behind the sidewalk/right of way line. Ana Gelabert-Sanchez Director Planning Department Page 2 December 22, 2005 6. Continuous pedestrian sidewalk is required across the entrance/exit driveways to the "drop-off" area located adjacent to S.E. 6 Street. 7. Verify with the Zoning Department that the column spacing/ clearance in the parking garages is sufficient. 8. The required loading spaces are not indicated in the site development information. The truck maneuvering space in the loading dock area is sufficient for single unit trucks (12'x 35' spaces) but is insufficient for tractor/trailer trucks (12'x 55'spaces). 9. All greenspace and landscaping required by the Zoning Ordinance must be accommodated on private property. Greenspace and landscaping within the public right of way cannot be included in the calculations for meeting greenspace zoning requirements. 10. Standard parking spaces are 8.5 feet wide and 18 feet long and require a 23 foot back-up distance. A Special Class II permit is required to reduce the back-up distance. 11. City of Miami driveway entrances, in compliance with A.D.A. standards, shall be required. Continuous sidewalk is required across driveway entrances. The maximum driveway width is 40 feet. Driveways must be five (5) feet off the side lot line where they cross the base building line. An FDOT permit is required for driveways on S.E. 7 Street. 12. 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 maintaiied 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. 13. 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. 14. Since this project is more than one acre in total construction area, the methods of construction must comply with the City of Miami Municipal Separate Storm Sewer Permit (MS4). This project will require a Florida Department of Environmental Protection (DEP) Stormwater, Erosion and Sediment permit. For information on a DEP permit application, please contact our department at (305) 416- 1200 or www.dep.state.fl.us/water/stormwater/npdes.

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.
