1.0 INTRODUCTION
1.1 Authorization
Coastal Systems International, inc. (Coastal Systems) was authorized by Balbino
investments, Inc., to evaluate the existing domestic water, sanitary and storm drainage
system for the proposed Hurricane Cove Development site.
1.2 Purpose
The purpose of this Development Evaluation is to report the potential impacts as a result of
the proposed Hurricane Cove Residential And Marina Project, which includes a residential
complex of 1,073 units and marina component for a total of 4.68 acres.
1.3 Site Location
The project site is located at N.W. North River Drive and 19`r' Avenue, on the north bank
of the Miami River, in the City of Miami, Florida. The existing building address is No.
1884 North River Drive. This riverfront property measures 7.91 acres including 3.23
access of submerged lands, having an upland area of 4.68 acres. The property is currently
being operated as a marina, boat yard, and boat storage facility.

AND DEMANDS

2M CODE REQUIREMENTS AND DEMANDS
2.1 Stormwater Management
The upland site covers 4.68 acres and is 98 percent impervious. The proposed site
development will improve the quality of water that runs into the Miami River, the
underground water source, and the City's environment. Presently, all existing pavement
surfaces and possibly some existing direct outfalls have direct run-off into the Miami River.
The proposed site development will correct and improve these conditions to prevent any
direct run-off into the Miami River and provide pervious areas to be planted with sod and
trees. This new development is proposing 0.30 acres of pervious areas and 4.38 acres of
impervious areas. The proposed storm water management system will be designed
according to Best Management Practices and will be consistent with the Miami -Dade
County Department of Environmental Resource Management, and South Florida Water
Management guidelines and design criteria.
2.2 Potable Water
The proposed development will require a water main extension since the street has an
existing 6-inch water line. The water main extension should be a minimum of 12-inches.
The connection for the extension would be at 16t Avenue and North River Drive. The 12-
inch line should provide sufficient capacity to the site; it is essential that an additional
213,379 gallons per day (gpd) will be required to meet the increased demand, and provide
connection for fire mains and fire hydrants.
2.3 Sanitary Sewer
The proposed site can be serviced by an existing 54-inch sanitary main that runs along the
centerline of North River Drive. There is also a 10-inch main that runs partially on the
north side of the road, which would be also available to service the site.

Daily Rate Gallonage for Water and Sewer:
I. Proposed Usage
a. 1,073 Apartments at 200 gpd 214,600 gpd
b. 100 Seat Restaurant at 35 gpdfseat 3,500 gpd
c. 130 Boat Slip Marina at 40 gpd 5,200 gpd
II. Existing Usage
a. 5,050 s.f. of office warehouse at 10 gpd/100 s.f 4,721 gpd
b. 130 Boat Slips at 40 gpd 5,200 gpd
The net total increase of water and sanitary daily gallonage for the proposed site
development is 213,379 gallons per day (gpd).

2.4 Solid Waste Generation
A Solid Waste management company would service the solid waste hauling for the
proposed development. The site is currently being operated by a marina with a dock
storage and boat yard and produces 26 CY per month reported by Solid Waste
Management Company, Miami, Florida. The existing docks will be used as a marina
facility for the condominium residences and are estimated to generate approximately 30
CY per month. The proposed residential development would generate approximately
1610 CY per month. The development would be using a trash compacting system that
uses 2 CY containers holding approximately 600 to 700 lbs. (refer to table 2.4a). The
proposed restaurant would generate approximately 130 CY per month.
Monthly Rate for Sold Waste:
1. Proposed Usage
a. 1,1 17 Apartments at 1.5 CY/unit 1,610 CY
b. 100 Seat Restaurant at 1.13 CY/Seat 130 CY
c. 130 Slips Marina at 0.2 CY/Slip 30 CY
d. Total Monthly Increase 1,744
