ENG L OSURES:
The Public Works 'Department has reviewed .the Large Scale Development plans for the
development located at 1770 North .Bayshore Drive and has the following conunents.
1. Platting of the property will be required in order to close and vacate the 10
foot alley within this property. As presented, the proposed structures
encroach into the alley. The proposed building is not permitted to encroach
into the public alley line at any level, above or below grade. Public Works
strongly recommends an early investigation into the platting requirements
for this site. Also, coordinate alley access with the adjacent proposed and
existing developments. The public alley is being used as access for the
delivery trucks of Hotel de I'Opera and 13ay Park Plaza.
2. 25 foot corner radius dedication is required at the intersections of the base
building lines at N.E. 4nd Avenue and N. Bayshore Drive with N.F. 18th
Street.
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. The City of Miami Capital
Improvement and Transportation Office is designing a roadway
reconstruction project for North Bayshore Drive and N.E. 1.8 Street. This
project includes raising the roadway elevation. Contact that office for the
proposed elevations of these roadways.
4. Provide dimensions of the loading, parking spaces, back up distances,
trash area and the stalls. Standard parking spaces are 8.5 feet wide and 18
feet long and require a 23 foot back-up distance. A Special Class 11 permit
is requireci to reduce the back-up distance. Verify with the Zoning
Department that the column spacing/ clearance in the parking garages is
sufficient. A building column interferes with truck maneuvering in the
loading area.
5. City of Miami driveway entrances, in compliance with A.D.A. standards,
shall be required. Continuous pedestrian sidewalk is required across the
entrance/exit driveways.
6. The "Plaza" on N.E. 4 Avenue has been included in the gross lot area
calculation. Verify ownership of the "Plaza" prior to including this land in
the calculation.

abutting the project site without requiring pedestrians to enter private
property. Along N.E. 18th Street, N.E. 4nd Avenue and N. Bayshore Drive,
the sidewalk must maintain a minimum of 5 feet in width in order to
comply with A.D.A. clearance requirements
8. 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 inust be located
on -site in an open area to accommoda..te future maintenance access.
10. 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.
11. All greenspa.ce and landscaping required by the Zoning Ordinance must
be acconunodated on private property. Greenspace and landscaping
within the public right of way cannot be included in the calculations for

12. Public Works policy requires that no closures of vehicular travel lanes will
be permitted during the course of construction unless a temporary
replacementlane, 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.
13. In order to mitigate traffic congestion and problems associated with
unregulated parkingthroughout 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

Sediment permit. For information on a DEP permit application, please
