Gvt-q GENERAL This proposal is submitted in response to the request by the City of Miami (CITY) for CDM (ENGINEER) to provide a Stormwater General Development Plan (SGDP) for the Kinloch Stormwater improvements Project. The project area as delineated by the CITY is approximately 0.5 sq. mi (320 acres). The project area is bounded to the east by Southwest 42nd Avenue, to the west by Southwest 47th Avenue, to the south by Southwest 8th Street, and to the north by Northwest 7th Street. The project area boundaries are shown on Figure 1. The study area may need to extend beyond these boundaries to account for proper hydraulic boundary conditions. The proposed SGDP will update the water quantity conditions and needs in the kinloch project area. The SGDP will estimate the impacts of existing land uses on flood protection. Also, the SGDP will identify infrastructure strategies to accommodate runoff from these uses for existing conditions, under the following storm events: 5-year, 24-hour10-year, 72-hour; 25-year, 72-hour, and 100-year, 72 hour. It is understood that the objective of the project is to develop Preliminary Engineering Designs to provide flood reduction. To maximize the effectiveness of the Preliminary Design, we propose some early data review and analysis tasks, to use prior work done by others, and to use a model to evaluate alternatives to present to the CITY. S. SCOPE OF WORK ENGINEER shall provide Engineering Services in accordance with the following Scope of Work: A. Task 1- Kickoff Meeting ENGINEER will conduct a kickoff meeting at the beginning of the project with the CITY and other interested stakeholders. ENGINEER will generate and distribute copies of minutes of this meeting. B. Task 2 -Data Collection and Review ENGINEER wilt collect and review available information such as records, maps, existing surveys, topographic information, as-builts plans, requirements of the agencies having jurisdiction over the project and other information which may have an impact on the planning, design, approval, permitting, construction or operation of the project. -1- pd3133 copel.doc 1018/04 consulting • engineering • construction • operations Figure 1 - Map of Project Area -2- pd3133seopel.doe 10/11/04 CITY shall provide aerial photographs in digital form of the study area, if available. Additionally, CITY shall provide, if availabie, data on soils, land use, and impervious area. The ENGINEER will review any available past studies (to be provided by CITY) of the project area and of pertinent surrounding areas including any DERM studies. Eased on these studies, existing stormwater facilities information and topographic data, ENGINEER will determine the hydraulic boundary of the study area, which may be greater than the aforementioned 0.5 sq. mi. Task 3 — Site Visits The ENGINEER will conduct a site visit to visually assess the general conditions of the project area. The ENGINEER will also conduct two additional site visits during the course of the project after rainfall events to observe and document with digital photographs flooding problems observed within the project area. D. Task 4 - Surveying Services ENGINEER will retain a registered surveyor to provide survey information required to delineate drainage basins and to complete modeling (Task 7). This information will include topographic information in City of Miami datum consisting of elevations within street right-of-ways at 100 foot intervals, intersections, and at locations where a change of grade exists. Elevations wilt be taken at roadway centerline, edge of pavement, flow line of curb, front and back of sidewalk, swale and top and bottom and apparent right of way line. In addition, surveyor will obtain rim and invert elevations, pipe sizes, direction and material for accessible and visible utilities. The Surveyor shall use as a basemap GIS maps obtained from the Miami Dade County Information Technology Department (ITD) in AutoCADD DWG format overlayed onto 2003 ortho rectified aerial photographs of the subject project area. Survey data (spot elevations) will be shown on this map. ENGINEER will coordinate with the surveyor to obtain this survey information. Additional survey information will most likely be required for design phase of this project (not included in this scope of work). ENGINEER will obtain available, existing utility information from CITY and utility companies. If existing underground utility information is unavailable or requires verification, the ENGINEER will retain the services of a Contractor to pot hole as needed to obtain field locations of existing utilities which may conflict with proposed improvements. Pot holing is a Contingency Item and not included in this task. The ENGINEER will submit one (1) signed and sealed set of survey drawings and an electronic copy of the survey to the City. E. Task 5 — Geotechnical Services ENGINEER will retain a qualified geotechnical firm to provide geotechnical information required to complete this project The geotechnical services that will be performed in the project area include conducting test borings and geotechnical -3- pd3l33seopelAce 10/VO4 laboratory analyses, and providing geoteohnicai and design recommendations support the proposed design elements of the project. The sub -surface soil investigation shall include: Standard Penetration Test (5), 20 feet deep to including standard soil analysis a Borehole Permeability Test (5), 15 feet deep including saturated hydraulic conductivity, per South Florida Water (41anagemert District • Double Ring Infiltrometer Test (2) The results of the geotechnical analyses will be documented in a report containing the following: • Presentation of the field and laboratory test procedures used. • Description of subsurface conditions, including subsurface profiles, estimated seasonal high groundwater table, saturated hydraulic conductivity, maximum and minimum infiltration rates, and soil storage capacity (inches) The ENGINEER will submit one (1) signed and sealed copy of the geotechnical report to the City. F. Task 6 — Meetings with Regulatory Agencies and Other Stakeholders ENGINEER will conduct up to three (3) pre -permitting meetings with regulatory agencies which are anticipated to have jurisdiction over this project as needed to discuss permit requirements including the Miami Dade Department of Environmental Resources Management (DERM), the South Florida Water Management District (SFWMD) and any other permitting agencies having jurisdiction over this project. G. Task 7- Hydrologic and Hydraulic Modeling for Existing Conditions without Control Measures For hydrology, ENGINEER will develop sub -basin delineations based upon the elevation data. The ENGINEER will estimate width, slope, infiltration, and groundwater parameters. The Directly Connected Impervious Area (DCIA) will be estimated from survey information and aerial photos. ENGINEER will calculate stage -storage areas and overland flow profiles between sub -basins. ENGINEER will estimate rainfall volumes (multipliers) for the 5-, 10- and 25 year storm events. The ENGINEER will multiply these volumes by the South Florida Water Management District (SFWMD) unit hydrographs for the 5-year, 24-hour 10-year, 72-hour, 25 year, 72-hour, and 100-year, 72 hour storm events. The RUNOFF block of XP-SWMM will be used by ENGINEER to compute surface runoff hydrographs for each sub -basin. The HYDRAULICS block of XP- SWMM will be used by ENGINEER to route the runoff through the network, conduits and overland flow. There will be a maximum of 20 sub -basin and 30 -4 - pd3133scopel.doc 104/04 junctions =and '.cnduits. ENGINEER will simulate the 3-year, 24 hour; 10-year, 24 hour; 25-year, 72 hour ; and 100-year, 72 hour storm events. ENGINEER will produce summary tables of flood stages by junction and peak flows for project area outfalls (if any). ENGINEER will then compare the resulting flood elevations and durations to the appropriate Levels of Service (LOS) based on CITY and/or Miami -Dade County criteria. Task 8- Identification and Ranking of Problem Areas Based on the modeling results from Task 7, ENGINEER will update problem areas from those preliminarily identified by CITY. In agreement with CITY, ENGINEER shall rank and prioritize the flood problem areas. Task 9 — Evaluation of Control Measures for Existing Conditions In coordination with CITY, ENGINEER shall identify up to four (4) types of stormwater control measures, which could be exfiltration trenches, baffle boxes, detention and/or retention storage, gravity storm sewers and pump stations and forcemains to attempt to mitigate the ten (10) quantity (flood) problem areas identified under Task 8. These control measures will be grouped in up to three (3) alternatives. Task 10 — Stormwater General Development Report ENGINEER will prepare a Stormwater General Development Report summarizing the findings of Tasks 1 through 9 above. The report will include layouts or General Development Plans for 3 recommended design alternatives (at 1 "=20©' scale on 11 "x17'sheet size) based on the results of the stormwater model evaluation performed under Task 6, for review by the CITY. The report will provide sufficient detail and information to depict proposed improvements, describe the level of service achieved and support the application for a permit from the SFWMD, DERM and other permitting agencies having jurisdiction over this project. ENGINEER will review the project's key design elements in comparison to CITY and SFWMD design standards for roadway and drainage, as well as any other applicable guidelines. K.
