The 3.80 acre site will contain the Miami -Dade County Children's Courthouse which will consist of a 14 -story, 371,500 square foot building as well as 66 judges, 18 police and 7 Miami -Dade Transit parking spaces (refer to Table 1, Project Summary). Currently, the site serves as an asphalt parking lot for the Stephen P. Clark Government Center and will be demolished as part of this project. Existing utilities, confirmed through survey, test hole extrapolation and Sunshine State One Call, such as gas, storm water and potable water lines traversing through the site will need to be relocated to facilitate construction. In addition, storm water, potable water and sanitary sewer lines also traversing through the site; however, determined to be not in use shall be removed in accordance with the utility agency having ownership. The site also contains chilled water lines traversing the site that will remain in place. The removal, relocation and addition of utilities are summarized in the following site utility study for the Miami -Dade County Children's Courthouse. Table 1: Project Summary Proposed Item(s) Floor Area (square feet) Units Courthouse 371,500 - Judge Parking - 66 Police Parking - 18 Miami -Dade Transit Parking - 7 2 i l Storm Water Management Existing Storm Water System Currently, the site serves as an asphalt parking lot. An existing 24 -inch concrete storm pipe, traversing the site from NW 3'"d Street to NW 41h Street and owned by the City of Miami Public Works, will be relocated out of the proposed building footprint to facilitate construction. As a result, a portion of new 24 -inch reinforced concrete pipe will be located along the western side of the site just east of NW 2nd Avenue. It will run westerly along NW 4th Street, then southerly through the site toward NW 3`"d Street, then easterly still within the property and _ parallel to NW 3'd Street and finally southerly, interconnecting to the existing City of Miami drainage system at NW T -d Street. An exclusive 10 -feet City of Miami easement will be required for the portion of storm water pipe within the site. The existing drainage system serving the parking lot will be demolished. A proposed storm water management system shall be constructed to address the storm water run-off from the proposed site improvements. Flood Criteria: The project site grade elevations shall adhere to the flood criteria according to State, South Florida Water Management District (SFWMD) and Miami -Dade County regulatory requirements as outlined below: 1. The proposed project is located in Panel 191 of 625 of Map Number 12025CO191J of the Flood Insurance Rate Map (FIRM). The project is located in Zone X where a base flood elevation has not been determined according to the National Flood Insurance Program (refer to Attachment B, FIRM). By definition, Zone X are areas of 500 -year flood; areas of 100 -year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 100 -year flood. This criterion will be used to determine the minimum proposed finish floor elevation. 2. The Miami -Dade County Flood Criteria elevation per Plat Book 120, page 13 . is estimated to be 5.50 ft NGVD (refer to Attachment C, Miami -Dade County 3 Flood Criteria). This flood criterion plus 4 -inches will also be used to determine the minimum proposed finish floor elevation. 3. The average October ground water level elevation is estimated to be 3.0 ft NGVD according to the Miami -Dade Department of Environmental Resources (DERM) and Miami -Dade County Public Works Manual, Part 2 Standard Detail WC -2.2 (refer Attachment D, Average October Water Level). This elevation will be used to determine drainage well capacity. Proposed Storm Water S ste Storm water nun -off from the Miami -Dade County Children's Courthouse will be contained on site. The proposed storm water management system shall adhere to the Florida Department of Environmental Protection (FDEP), SFWMD and Miami -Dade County regulatory requirements. The 5 -year storm event will be used to design the storm water infrastructure and shall be in accordance with Miami -Dade County Public Works Manual, Part 2 Section D4 — Water Control. The run-off will be collected through a mixture of catch basin inlets, trench drains and yard drains located at low points and are interconnected through a series of hydraulically sized storm pipes composed of high density polyethylene (HDPE) in accordance with jurisdictional requirements. No exfiltration trenches are proposed within the project boundaries. The storm water run-off will eventually be piped to a continuous deflection separation (CDS) unit to separate debris, oil and grease, and then discharged to an underground, non -drinking water aquifer through storm water injection wells. The project will require four 24 -inch diameter injection wells to provide sufficient capacity to dispose the storm water run-off from the 5 -year 24-hour storm event generated by the developed site based upon drainage well calculations (refer to Attachment E, Drainage Well Calculations). In summary, the proposed storm water management system shall be designed to be in accordance with FDEP, SFWMD and Miami -Dade DERM regulatory requirements. 0 i 1 Potable Water i Miami -Dade Water and Sewer Department (M-DWASD) owns and maintains the potable water system abutting and traversing through the project site. The existing water mains are summarized in Table 2. Table 2: Existing M-DWASD Water mains (Refer to Attachment F, Water Atlas F -14-B) Size Material Location Between 6 -inch Ductile Iron NW 2°d Avenue NW 3d Street & NW 4`' Street 8 -inch Ductile Iron NW 3 rd Street NW 2" Avenue & NW I" Avenue 12 -inch Cast Iron NW 4`' Street NW 2" Avenue & MDT Right of Way 20 -inch Ductile Iron Project Site NW 3r Street & NW 4" Street 30 -inch Concrete NW 2" Avenue NW 3r Street & NW 4" Street The proposed flow from the site is 37,150 gallons per day as determined by Exhibit `B" of Miami -Dade County refer to Table 3. As outlined in the M-DWASD Water and Sanitary Sewer Agreement Points of Connection, potable water service shall be provided by the existing 12 -inch cast iron water main along NW 4th Street. Additionally, the existing 12 -inch water main shall be interconnected to the existing 30 - inch concrete water main along NW 2nd Avenue. Furthermore, the existing 20 -inch ductile iron water main crossing through the site from NW 3rd Street to NW 41h Street, shall be relocated out of the proposed building footprint to run easterly along NW 4`h Street, then southerly, adjacent to the proposed police and MDT service driveway on the east side of the site and finally run westerly along NW 3rd Street interconnecting to the existing 20 -inch water main; therefore maintaining a looped system. An exclusive 12 -feet M-DWASD easement will be required for the portion of water main crossing through the site. The existing 8 -inch ductile iron water main along NW 3rd Street shall also be 5 interconnected to this proposed 20 -inch water main. Water service meters shall be provided by M-DWASD upon certification of the water system.

Currently, there are two existing fire hydrants. One is located along NW 3'd Street on the southside of the street and the other is located along NW 4t" Street on the southside of the street (refer to Attachment H, City of Miami Fire Department Hydrant Atlas). The existing fire hydrant along NW 41h Street shall be removed due to its conflict with proposed construction. The fire hydrant will removed per M-DWASD standards as outlined in the M-DWASD Water and Sewer Agreement. Furthermore, a new fire hydrant shall be installed and served by the existing 12 -inch cast iron water main along NW 4"' Street. It shall be located at the southeast corner of NW 2nd Avenue and NW 4th Street as outlined by the City of Miami Fire Rescue and Inspections Services Department. Lastly, the fire line to the internal fire protection system of the proposed building shall be served from the existing 12 -inch cast iron water main along NW 41h Street. Sanitary Sewer Miami -Dade Water and Sewer Department (M-DWASD) owns and maintains the sanitary sewer system abutting and traversing through the project site. The existing sanitary sewer lines are summarized in Table 4. C Table 4: Existing M-DWASD Sanitary Sewer Lines (Refer to Attachment I, Sewer Atlas F-14) Size Material Location Between 8 -inch Terra Cotta Project Site NW 3 rd Street & NW 4 Ih Street gravity 371,500 10 gpd/100 square feet* 37,150 12 -inch Ductile Iron NW 3rd Street NW 2°d Avenue & NW 151 Avenue gravity 15 -inch Vitrified Clay NW 2"d Avenue NW 3 rd Street & NW 4 Ih Street gravity 60 -inch Concrete NW 4t' Street MDT Right of Way & forcemain nd NW 2 Avenue The existing 8 -inch terra cotta sanitary line has been confirmed to be out of service through test hole exploration and verification from M-DWASD. The proposed flow from the site is 37,150 gallons per day as determined by the Exhibit "B" of Miami - Dade County (refer to Table 5). As outlined in the M-DWASD Water and Sanitary Sewer Agreement Points of Connection, proposed sanitary sewer lines shall be connected to the existing 12 -inch ductile iron sanitary sewer line along NW 3'd Street. The operating conditions and available capacity of the downstream M-DWASD receiving pump station shall be determined once a Utilities Transmission Form has been issued and plans have been submitted to Miami -Dade DERM. Table 5: Sanitary Sewer Schedule of Daily Rate Gallonage *(Refer to Attachment G, Per Miami -Dade County Attachment "B") Land Use Quantity Gallons Per Day Total Average Daily Flow (square feet) (gpd) (gpd) Office 371,500 10 gpd/100 square feet* 37,150 Building sA i J _ Gas Currently, a 6 -inch welded steel gas line owned and maintained by Teco People's Gas traverses through the site from NW 3'd Street to NW 4"' Street. It conflicts with the proposed building footprint. The existing pipe will be removed per Teco People's Gas standards. As a result, a new 6 -inch gas line shall be installed running easterly along NW 4"' Street, then southerly through the project site and finally westerly along NW 3rd Street interconnecting with the existing 6 -inch gas line. An exclusive, 6 foot easement will be required for the portion of gas line crossing through the site. Chilled -Water Currently, two 20 -inch ductile iron chilled water lines, owned and maintained by Miami -Dade County GSA traverses through the site from NW 3'-d Street to NW 4"' Street on the eastern side of the project site. They do no conflict with any proposed construction and shall remain in place. Sufficient clearance will be maintained relative to all proposed utilities running adjacent or crossing them. Summary The proposed Miami -Dade County Children's Courthouse will require the removal and/or relocation of existing utilities as well as the installation of a new utility infrastructure. The proposed utility relocations and new utility layouts will not be considered final until approval has been obtained from all regulatory agencies having jurisdiction. The three existing utilities to be relocated (24" concrete storm pipe, 6" welded steel gas line and 20" Ductile Iron water main) lie within a non-exclusive 50' easement which bisects the site from NW 3'd Street to NW 4`1' Street. A hold -harmless agreement shall be sought from the respective utility owners by the property owners in conjunction with granting the required easements for the proposed utility relocations. 9 Attachment A Location Map U NW 10TH NW 7TA ST �I IN z zl NW 5TH ST I I -- NW 'fL 1STI ST v LOCATION MAP SCALE: N.T.S.
