Depending upon the existing available data, additional soil sampling, well flow testing, and other data may need to be obtained. If requested by the Airport, Jacobs will provide services to obtain this CL information. TASK 1.2 BUILD COMPUTER MODEL OF EXISTING SYSTEM 1.2.1 SET UP MODEL 2 Hydrologic and hydraulic modeling performed in this and subsequent tasks will be for the existing Primary Stormwater Management System (PSMS). Items A through J (shown below) indicate the input data cV applicable to the analysis of the PSMS, utilizing version 5 of the RUNOFFLO (hydrology) and EXTRAN (hydraulics) blocks of the United States (US) Environmental Protection Agency (EPA) Stormwater Management Model r (SWMM). CL N A. Tributary Area - Jacobs will determine tributary areas at the base scale (I" = 200'). B. Rainfall Hyteographs - Jacobs will develop rainfall hyetographs for the 100-year, 72-hour; 25-year, 72-hour; 5-year, 24-hour and 2.5- E inch storms based on rainfall volumes and distribution data available from SFWMD. C. Basin Slope-Jacobs will calculate an average slope for each basin. D. Directly Connected Impervious Area (DCIA) - Jacobs will calculate the percentage of directly connected impervious area by basin. A maximum of six land use categories (Terminal, commercial, Page 6 of 14 Packet Pg. 1885 J.9.a industrial, pavement, water\wetland, and grass) will be utilized to develop typical DCIAs for each basin. These DCIA values for each land use type will be based upon representative percentages for similar areas. E. Stage/Area/Storage - Jacobs will establish stage/area storage relationships for applicable basins (where appreciable storage CL exists). F. Soils Data -Jacobs will estimate soil storage and infiltration rates for each basin based on available data from the Inventory or NRCS. Soils will be characterized as NRCS Hydrologic Groups A, B, C and D. G. Other Hydrologic Parameters - Jacobs will estimate roughness 15 LO coefficients for other parameters, such as overland flow and initial abstraction (surface ponding), based on available data. o H. Primary Stormwater Management System (PSMS) Schematic CL - Jacobs will develop the PSMS schematic on the base map in Task 1.2.A. This PSMS schematic will show general flow trends and will provide a means of identifying model output for SWMM RUNOFF and EXTRAN on maps at scale (1"=200'). The minimum pipe size for modeling shall be 24 inches. I. Cross Sections- Jacobs will code cross sections for channels, swales, CL and overland flow. J. Hydraulic Data - Jacobs will incorporate necessary hydraulic data into the hydraulic model(s) for equivalent hydraulic representation of the PSMS. Jacobs, in consultation with Airport, will determine which data are necessary. Jacobs will review data and determine what elevation to use at the canal outfalls, for each of the design storms. N K. Tidal information - Jacobs will use the latest FDOT method to 15 LO determine the tailwater elevation based upon available tidal data. T_ L. Sea Level Rise - Jacobs will run an additional model run for the existing and two proposed scenarios based upon the published CL Unified Seal Sea Level Projection, published in October 2015. The purpose of this modeling will be to illustrate the impact of the anticipated sea level rise on the stormwater infrastructure. Jacobs will provide a drainage report discussing the methodology and making reference to the input data prepared. The input data set resulting from the model set up will become part of the appendix tables in the final SWMP Drainage Report. This information quantifies the hydraulic and hydrologic characteristics of the study area and is a fundamental part of the overall stormwater master planning effort. In addition to the input data sets provided in the appendices,various components of the model set-up described above will be incorporated in the final Drainage Report in order to provide a better understanding of the stormwater management system and Page 7 of 14 Packet Pg. 1886 J.9.a specific modifications that may be required due to future airport improvements. The stormwater model will also be delivered in digital form (input, output and executable files). 1.2.2. CALIBRATE MODELS Jacobs will review rainfall, recorded water elevation data (in and near the airport), and high-water marks for large storms occurring within the last 10 years (with recurrence frequency of once in 10 years or more, if possible). Jacobs shall list largest storms considered; provide discussion on how storm used for calibration was selected and describe any caveats that need to be considered when interpreting model based on this calibration. 15 LO Based on available data, Jacobs will select a storm with sufficient data to cv be used for model calibration. Jacobs will simulate the rainfall event for o this storm and calibrate the model by adjusting the hydrologic (e.g., soil CL storage and land cover parameters) and hydraulic (e.g., Manning' roughness coefficient) parameters until the predicted peak water elevations reasonably match the observed values. The methodology and results will be included in the SWMP Drainage Report. 1.2.3 SIMULATE DESIGN STORMS Jacobs will simulate the 100-year, 72-hour; 25-year, 72-hour; 5- year, 24- CL hour; and 2.5-inch storms using the model parameter values obtained in calibration. The SWMP Drainage Report will include summary tables of peak flood stages for each design storm under present and future land use conditions with existing hydraulics (2 scenarios). E 1.2.4 IDENTIFY BOTTLENECKS Based on the existing flooding and design storm simulation results,Jacobs will identify locations where significant restrictions to flow exist. Jacobs N will summarize these findings in the SWMP Drainage Report, including a LO map layer identifying the locations of these restrictions (1 "=200'). T_ TASK 1.3 FIELD DATA CL 1.3.1 FIELD SURVEYS N Jacobs will use the most recent LIDAR survey of the airport that is made available by the Airport. Details of required survey services will be determined once existing Survey data has been assimilated. The survey requirements in order to prepare the Drainage Masterplan and Model will be current topographic survey elevations of the airfield and apron, and the areas 100 feet beyond the perimeter of the airfield fence. All stormwater drainage structures and pipe culverts along with rim and invert elevations will be required. Tidal water levels in the salt marsh will need to be recorded to determine correlation with ocean tide levels. Spot elevations of buildings and pavement locations as recommended by Page 8 of 14 Packet Pg. 1887 J.9.a Jacobs. A. Depending upon the existing available data, additional survey data may need to be obtained. If requested by the Airport,the Jacobs will provide services to obtain this information. Services for Article A will be provided under a lump sum basis. ARTICLE B-GRAVITY DRAINAGE WELL CLEANING &TESTING E e TASK 2.1 DEVELOP ACTION PLAN AND PERMITTING cv 2.1.1 ACTION PLAN 15 LO Pre-fieldwork planning will be accomplished with Complete Services Well Drilling, Inc.to plan the execution of the work, coordinate with the Airport, and develop a summary of any action items that need to be accomplished CL prior to the team arriving onsite. During this time, coordination with the subcontractor will occur and the health and safety plan will be developed prior to work commencing. i 2.1.2 MOT PLAN The gravity drainage well cleaning/testing will impact Faraldo Circle and Stickney Lane.Jacobs will develop an MOT Plan to manage pedestrian and CL car traffic in these areas. 2.1.3 FDOT PERMITTING Jacobs will provide permitting services to obtain a Florida Department of Transportation right-of-way permit to discharge to a storm inlet on Roosevelt Blvd. TASK 2.2 CLEANING AND TESTING GRAVITY DRAINAGE WELLS `V LO To avoid disturbances to aircraft traffic, landside gravity drainage wells P- 1 and P-6 were selected for flow testing and cleaning. Testing and r cleaning of the two selected gravity drainage wells is described below. CL 2.2.1 PRE-CLEANING PERFORMANCE TESTING OF THE WELLS 0 Prior to cleaning,each selected well will be flow tested with potable water to evaluate the general performance of the drainage wells to accept and drain stormwater to the underlying aquifer system. The pre-cleaning flow test for each gravity drainage well will generally be performed as follows; A. Mobilize a 21,000-gallon frac tank, piping, and support equipment to the wel I site. B. Connect the frac tank to the gravity drainage well using watertight piping and valves. This may require a temporary well flange or other wellhead sealing device to be welded and/or attached to the top of well Page 9 of 14 Packet Pg. 1888 J.9.a casing so that a watertight connection can be made between the well and the frac tank. C. Isolate the frac tank from the gravity drainage well using a valve. D. Fill the frac tank with potable water using a nearby fire hydrant. E. Open the isolation valve and drain the frac tank at a constant flow rate while continuously measuring the well's water level. The flow test will be finished once the frac tank has completely drained or until the field team feels that an adequate test has been conducted. With an anticipated drainage rate of approximately 1,000 gpm, potable water will be injected into each drainage well for approximately 20 minutes. A centrifugal pump may be required to maintain a constant flow rate during flow testing. LO F. The flow rate and water levels will be used to quantify the drainage performance of each well by calculating specific injectivity, which is typically described in terms of gallons per minute per foot of water level CL change (gpm/ft). 0 G. The anticipated work footprint around each drainage well, the frac tank, and piping is also shown in Figure 1. 2.2.2 CLEANING OF THE GRAVITY DRAINAGE WELLS CL The gravity drainage wells will be cleaned to remove sediment and debris that has likely collected in the wells over time. Wells will be cleaned primarily using air lifting methods that are standard well development techniques of the industry. Air lifting of the wells will be accomplished by installing a temporary tremie pipe in the gravity drainage well at an appropriate depth and then applying compressed air to the well through the installed pipe. Air will enter the well at the bottom of the pipe and then quickly travel up the well to the surface expanding in volume as it cv moves upward. This upward movement and expansion of the compressedLO air pulls water and other loose material from the well and lifts it to land surface. As water is evacuated from the well, the cycle is completed when water CL from the aquifer system recharges the well's open borehole; this action helps flush and clean the well. The well can be surged or constantly air lifted to enhance development and cleaning of the well rather quickly. It is anticipated that air lifting of the well will be completed within an hour after the beginning of the initial air application. During air lifting, discharge water may be directed from the gravity drainage wells to the 21,000-gallon frac tank where suspended material will settle out. After settling, it is assumed that the discharge water will be directed from the frac tank to the discharge locations shown on Figure 1. Sediment or other foreign debris collected in the frac tank will be disposed of by Complete Services. If necessary, a filter sock, or similar Page 10 of 14 Packet Pg. 1889 J.9.a material, may be installed on the end of the discharge piping to help minimize sediment transport offsite. Furthermore, the team may install sandbags and hay bales round the well being air lifted to help contain and prevent any trash or foreign material removed from the well from re- entering the well. 2.2.3 POST-CLEANING PERFORMANCE TESTING OF THE WELLS After air lifting the gravity drainage wells, each well will be retested for drainage capacity as described in the "pre-cleaning performance testing" procedures above. The pre- and post- cleaning flow testing results will be compared and evaluated to determine if cleaning the wells using air lifting techniques is effective at increasing the drainage capacity of the wells. This will help the airport team determine a best path forward for LO improving the drainage performance of the remaining gravity wells and drainage systems at EYW. CL TASK 2.3 REPORTING AND RECOMMENDATIONS 0 2.3.1 TECHNICAL MEMORANDUM A Gravity Drainage Well Technical Memorandum will be prepared to summarize the methods and approaches used during the cleaning and testing work. The TM will also provide results and recommendations for approaches to be used during future improvements. CL Services for Article B will be provided under a lump sum basis. ARTICLE C -STORMWATER MASTERPLAN AND ENVIRONMENTAL PERMIT APPLICATIONS TASK 3.1 STORMWATER MASTER PLAN AND DRAINAGE REPORT N 15 LO 3.1.1. EVALUATION OF ALTERNATIVES cv Jacobs will evaluate and describe up to two different alternative solution combinations. The analysis will be conducted for existing land use CL (including all currently permitted projects) and for an ultimate ("buildout") land use based on the approved ALP. The existing land use condition will encompass existing conduits, conduits under construction or conduits under final design. Thus, Jacobs will analyze a maximum of four scenarios (two alternative drainage systems for existing and future land use plans). The analysis will include possible use of on-site detention basins, drainage wells, exfiltration trench, backflow check valves, or other drainage features. Specific detention basin locations to be determined in consultation with Monroe County Airport Staff. Jacobs will apply the calibrated models for each of the four design storms. Jacobs will also assess the potential for the following stormwater Page 11 of 14 Packet Pg. 1890 J.9.a management options: A. Adjusting watershed boundaries and/or for interconnecting watersheds. B. Exfiltrating storm water into the groundwater system (wells, exfiltration trenches). C. Berm airfield perimeter and pump to temporary ponding areas (considering FAA constraints). D. Increasing existing offsite discharges, or additional points of E discharge based on expected groundwater / tidal levels and the computed water elevations during the design storms. 15 LO E. Other possible stormwater management options determined during information gathering task. o The above list of stormwater management options shall be finalized and CL accepted by the Airport, prior to proceeding with analysis. 0 3.1.2 DEVELOP AND ANALYZE STORMWATER MASTER PLAN Based on the foregoing analysis and review comments from the Airport, Jacobs will further evaluate the two alternatives for existing and future land use conditions (i.e., 4 scenarios) including probable capital costs, operation and maintenance costs and develop an overall plan that meets CL the airport's levels of service and regulatory agency guidelines.Jacobs will develop a list of"pros"and "cons"for each alternative. Jacobs will prepare maps showing the location of recommended facilities (one alternative at 1"=200' scale), (one alternative) prepare a summary table of the probable capital costs of improvements and provide a discussion of the SWMP in the recommendations section of the Drainage Report as indicated below. N 3.1.3 SWMP DRAINAGE REPORT LO N Following review comments from the Airport on previous submittals o (tables and memos), Jacobs will develop a Drainage Report which will CL address the following: N - Introduction - Data and Methodology - Results E - Alternatives - Recommendations - Cost Effectiveness - Permitting Issues - Implementation Page 12 of 14 Packet Pg. 1891 J.9.a The Drainage Report will provide the essential information on the above topics in the text narrative in the style of an Executive Summary. Supplementary information such as detailed tables, computer printouts and detailed maps will be provided in separately bound appendices in hard copy and/or digital form as appropriate. TASK 3.2 PERMIT APPLICATIONS A coordinated and detailed schedule of Permitting efforts, activities and responsibilities shall be developed. 3.2.1 DEVELOP AND ANALYZE STORMWATER MASTER PLAN FOR FUTURE DEVELOPMENT Jacobs will prepare conceptual plans, sketches, computations, and LO develop the information necessary to prepare permit application forms in accordance with the result of the consultation with the agencies having jurisdiction, in order to: CL N A. Prepare an airport-wide conceptual Environmental Resource Permit (ERP) application to SFWMD. Non-stormwater environmental elements (such as, wetlands, wildlife and water quality etc.) are not anticipated to be required at this time.This scope does not include any field data collection or research on other such non-stormwater related >- environmental information as may be required for the non-stormwater `' CL environmental elements of the ERP. Jacobs shall request work authorization if such data or research is required. a, B. Depending upon the need to obtain non-stormwater related environmental information for the processing of the ERP,the Jacobs, if requested by the Airport, will provide services to obtain this information. C. This scope excludes work effort involving securing the rights to offsite cv lakes / ponds or discharge facilities not owned by the Airport. If any LO work related to the securing rights to offsite lakes, ponds or discharge facilities, becomes necessary, these work items may be added as an r Additional Optional Service. CL Jacobs plans to submit ERP surface water management applications that are in conformance with jurisdictional agencies' standard stormwater requirements and/or represent a compromise between competing requirements (such as storage requirement by SFWMD versus ponding limitation by FAA).The level of effort in this scope assumes a reasonable stance by regulatory agencies (i.e., no new rules or special criteria or expanded geographic coverage). Accordingly, Jacobs anticipates having to prepare responses to two rounds of standard Requests for Additional Information (RAls).
