ENCLOSURES:
Large Scale Development
Review - ONE
The Public Works Department has reviewed the Large Scale Development plans for the
development entitled ONE, located at 2340 S.W. 32 Avenue and has the following comments.
1. Ten (10) feet of right-of-way dedication is required along S.W. 23 Terrace at Lot 38.
2. A ramp slope of 8% exceeds the maximum slope recommended for parking vehicles.
Architectural guidelines recommend a maximum slope of 6.5% where parking is permitted
on ramps.
3. Insufficient space is provided in the loading area for truck maneuvering. Trucks must exit
the property in a forward direction and must not back-up into the right-of-way.
4. Planter "bulb -outs" are not permitted on S.W. 23 Street. The existing continuous landscaped
parkway shall remain with parallel on -street parking.
5. Landscaping within the sidewalk area is not permitted on S.W. 32 Avenue. Continuous
pedestrian sidewalk is required within the public right-of-way abutting the project site
without requiring pedestrians to enter private property. All greenspace and landscaping
required by 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.
6. City of Miami driveway entrances, in compliance with A.D.A. standards, shall be required.
Continuous sidewalk is required across driveway entrances. Curbed street -type entrances are
not permitted.
7. Street elevations surrounding the building site vary significantly (greater than 2 feet). All
transitions from the established street profile grade to the building flood 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.
8. Poor soil conditions exist throughout the Douglas Park neighborhood and stormwater
drainage is problematic. This factor must be considered for constructability and drainage of

the underground parking levels. Discharge of construction excavation water into the public
right-of-way is not permitted. All stormwater must be retained on site including the
driveways and plazas on private property adjacent to the public streets. All 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.
9. 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.
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. 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.
12. 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.
13. 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 the Public Works Department at (305) 416-1200 or
www.dep.state.fl.us/water/stormwater/n des.
The Public Works Department will require the following street improvements:
S.W. 23 STREET: Construct missing section of curb and gutter and replace all damaged
sidewalk, curb and gutter adjacent to the site. Construct new pavement in missing parking lane
and mill and resurface entire width of existing pavement adjacent to the project site. Re -sod
parkway and install new street trees as approved by the Public Works Department.
S.W. 32 AVENUE: Replace damaged sidewalk, curb and gutter adjacent to the project site. Due
to the narrow width of the sidewalk, street trees are not permitted in the right-of-way.

S.W. 23 TERRACE; Construct curb and gutter and paved parking lane in accordance with City
standards. Replace all damaged sidewalk and mill and resurface entire width of roadway
adjacent to the project site. Construction of planter "bulb -outs", if approved by the Public Works
Department, will require construction of improvements to the stormwater drainage system.
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. The streets and avenues adjacent to the project site must be clear of dust and
construction debris at all times. Construct A.D.A. compliant handicap ramps at both street
intersections.
If you have any questions concerning these comments, please call Mr. Leonard Helmers,
Professional Engineer IV, at extension 1221.
