Currently, the site is vacant. However, there are large trees on site and wooden poles sustaining over -head wires. The Park Lane Tower project consists of a 420 ft. high mixed -use tower with 143 residential units (246,384 sq. ft. of living space), 13,000 sq. ft. of retail space, 24,601 sq. ft. of office space and 2,100 sq. ft. (40 seats for patron use) for restaurant use. See Table 1, below for further details of the proposed project.

Drainage Existing Drainage Based on site observations and available info illation, there is no existing drainage system in place at this site. A new storm -water management system will be constructed to retain the runoff generated by the proposed improvements, as required by code (see below). Proposed Drainage System The drainage system for the proposed development will consist of drainage wells and exfiltration trench, if possible, to facilitate on -site disposal of storm water runoff. The 5- year design storm event will be used to design the stoiui water management system, in accordance with Section D-4, "Water Control", of Part 2 of the Miami -Dade County Public Works Manual. Based on preliminary calculations, it is anticipated that four (4) 24" drainage wells will provide sufficient capacity to dispose of the design 5-year 24-hour storm water runoff generated by the proposed development. Preliminary drainage computations for the project areas are provided. in Attachment "B," Preliminary Drainage Well Calculations, which includes the basis for design. The final drainage design for the project should be in confoii uance with the requirements of the Miami -Dade County DERM Water Control Section, Florida Department of Environmental Protection, and other local, state and federal regulatory agencies having jurisdiction over the project. II. Water Distribution System The water mains owned and operated by the Miami -Dade Water and Sewer Department (MDWASD) in the vicinity of the project are shown in the Table 3. Park Lane Tower Site Utility Study Page 3 Table 3: Existing Water Mains (Per MDWASD Water Atlas Sheet) Location Between Water Main(s) NE 4d' Ave. NE 32fl1St. & NE 33`d St. 8" Biscayne Blvd. NE 32'1St. & NE 33rd St. 16" D.I. NE 32nd St. Biscayne Blvd. & NE 4th Ave. 6" & 12" (wl stub -outs) NE 33rd St. Biscayne Blvd. & NE 4th Ave. According to the water atlas provided by MDWASD, the 12" main on NE 32nd St. is stubbed out. There is a good possibility that MDWASD will mandate this 12" water - main to be extended and connected once they become aware the proposed project is a tower. A final determination of the points of connection and requirements will not be provided by MDWASD until a Water and Sewer Agreement is executed by the owner. Water service meters will be installed by MDWASD forces at the owner's expense. Service lines for domestic water, fire sprinkler systems and irrigation could be connected to the on -site water distribution system. Water service meters would need to be purchased, and then installed by MDWASD forces. See Attachment "C" for a copy of the MDWASD water atlas sheet for the project area. III. Sanitary Sewer Collection System Table 4 depicts the sanitary sewer mains owned and operated by Miami -Dade Water and Sewer Department (MDWASD), within the vicinity of the project.

The proposed on -site sanitary sewer system for the property can be connected to either of the existing mains abutting the property; provided that the line has enough capacity to handle the existing flows plus the additional flaws generated by the proposed project. A letter of availability and further coordination with MDWASD is recommended to verify the proposed sanitary sewer service connection points and requirements for this project. MDWASD may require upgrades to the sanitary sewer system, but this can not be determined without first obtaining a water and sewer agreement. A copy of the MDWASD Sewer Atlas sheet has been attached (See Attachment C). The flows from the existing MDWASD sanitary sewage mains on Biscayne Blvd. and NE 28th Street are received by MDWASD Regional Pump Station #2. As of December 2004, this pump station is operating under capacity as established by the USEPA, and is not under any type of moratorium (see Attachment "D" Pump Station Monthly Information). At this time, it is not anticipated that any improvements to the regional pumping and/or transmission systems will be required to connect the proposed project. However, a final Page 5 • determination regarding the status of the existing transmission system and the need for possible improvements will not be made until construction plans are submitted to the Miami -Dade County DERM Wastewater Section, and a Sanitary Sewage System Capacity Certification Letter is issued. The flows created by this project have been determined and are shown in Table 5.

Solid Waste Generation The solid waste generated by this development will be collected in standard on -site containers for refuse and recyclables. Regular pick-up service will be provided either by private hauling companies and/or by the City of Miami Solid Waste Department, who will transport the waste to Miami -Dade County or private disposal and recycling facilities. The volumes of solid waste projected to be generated by the project are shown in Table 6.

There is no easement by Plat, but there is a possibility that an easement by instrument exists. Further research by the surveyor is recommended to determine if an easement exists. These wires will have to be relocated to facilitate the proposed project. Coordination with the respective agencies will be necessary. r 1 1 1 1 • ✓ 91111/ Park Lane Tower Site Utility Study 110 Page 7 110 r r r r 0 r r r r r r r r r • II r r 1 r IP I. 0 i 1 D D D D D D D 0 1 1 I ID 10 10 Park Lane Tower Site Utility Study Attachment A Site Location Map Page 8 • :::--in Kimley-Horn and Associates, Inc. 420 Lircoin Road 5u'de 353 Miami Beach, F[odcle 33139 Phone: 305-573-2025 Fax: 305-673-4882 PARK LANE TOWER SITE LOCATION MAP r r PS r r r r r r r r Attachment B Preliminary Drainage Well Calculations ✓ O ✓ ✓ ✓ Park Lane Tower ✓ Site Utility Study Page 9 ✓ ✓ r Pio trsA 4_4.00 € fz zg Kinley-Horn and Associates, Inc, 420 Lincoln Rood Suite 353 Miami Beach, Florida 33139 Phone: 305-673-2025 Fax: 305-673-4882 ar#-"Etatit Mr SiwleA'T fri tor 5Z 4. e a PROJEC S!TE55 PARK LANE TOWER FLOOD CRITERIA MAP ar PO r ss r 411004 402 •1 Ern Cimiey-Horn and Associates, ,ittrfx 1691 Michigan Ave Suite 400 Miami Beach, Florida 33139 Phone: 305-673-2025 Fax: 305— 673 -- 4882 y 4 T i ytii•Vs e49 --2 (ESTIMATED) INTERVAL 1_t ,FOOT t wed) MEAN SEA 'LEVEL.
