In order to continue implementing the pollution prevention authority granted by the State of Florida, the LRECD has established a prioritization program for replacing the septic tanks with sanitary sewer systems. The septic tank replacement program includes the area east of I-95, North of Donald Ross Road, South of Johnathan Dixon State Park and West of the Atlantic Ocean. In 1979, Russell & Axon prepared the "Septic Tank Study — Phase I" report. This document identified several neighborhoods for sewering, and arranged the neighborhoods in priority order for sewering. Over the past 20 years, The LRECD has provided sewers to approximately 2,600 homes in 13 separate neighborhoods. At present, the LRECD program is based on a 1994 internal update of the plan which identified four areas for sewering. Two have been completed (Jupiter River Estates and Limestone Creek), and two are pending (Tequesta Peninsula and Area D). The 2002 Plan efforts will assume completion of these two areas in the next two years. The Septic Tank 2002 Plan will update the previous plans and extend the sewer installation program through the Year 2000 and beyond. I I I Mathews Consulting, Inc. 7 Section 2 Description of Study Area As stated previously, the septic tank replacement program includes the area east of I-95, North of Donald Ross Road, South of Johnathan Dixon State Park and West of the Atlantic Ocean. Figure 1 details LRECD's existing septic tank areas. Not all of the existing septic tank areas were included in the Septic Tank 2002 evaluation. Those areas are described below with the reason for exclusion from the study. • Palm Gardens — under consideration for County sewer installation. • Cinquez Park— under consideration for County sewer installation. • W. Center Street— low density area, partially sewered. • N. Caloosahatchee - area too small, cost prohibitive. • AIA-North—sewers in place, residents in process of hooking up. • Clemmons Street - sewers in place, residents in process of hooking up. • Jupiter Lighthouse Park— area too small,cost prohibitive. • Rivers Edge/Island Country Estates— low density area(>2.5 acres/lot). • New Palm Beach Heights — area too small, under consideration for County sewer installation. • Loggerhead Park- area too small, under consideration for County sewer installation. The twenty-eight areas included in the study were grouped together according to similar characteristics such as population density, location relative to surface water, and age of neighborhood. The resulting twelve study areas are listed in Table 1 and shown on Figure 2. 2-1 Mathews Consulting, Inc Atlart.tic Ocean, ep JONATHAN DICNINSON STATE PARK 1 `'� 7rN is IV \1'; ... y t d \ ,_ \..,,�� 1It2?

However, these areas have significantly different densities. The feasibility of sewering these areas as currently grouped should be further evaluated based on other considerations, including political and economic factors. 2-2 Mathews Consulting, Inc. Section 3 Evaluation Methods and Criteria The evaluation of each study area was based on several criteria that affect the operation and performance of septic tanks. The criteria is listed below: 1. Soil Association — The soil characteristics surrounding a septic tank affect the performance of the drainfield and the ability to properly absorb the effluent as required by design standards. The soil associations for the study area were obtained from the soil survey of Palm Beach and Martin Counties published by the United States Department of Agriculture (USDA) Soil Conservation Service (SCS). The soil survey provides information regarding degree of soil limitations for septic tank drainfields based on permeability, depth to seasonal high water table, depth to bedrock, slope and susceptibility to flooding. Two ratings are given for this purpose: "slight" and "severe". A "slight" rating is given to those soils that have properties favorable for septic tank drainage. A "severe" rating is given to those soils having properties that are not satisfactory for septic tanks. The soil characteristics of the study areas are shown in Figure 3. A detailed description of soil the associations is included in Attachment A. 2. Water Table Elevation — Elevation of the water table relative to the septic tank drainfield also affects performance of the system. A high water table reduces the effectiveness of the drainfield to properly disperse and absorb the effluent. The State of Florida Department of Health recommends that groundwater levels be a minimum of 2 feet below the bottom surface of the drainfield (or 3 feet below grade for a standard subsurface drainfield) for acceptable septic tank operation. (Reference: Chapter 64E-6 Florida Administrative Code). Groundwater levels were obtained from SFWMD local area monitoring well data and USGS grade elevations. Areas were evaluated based on whether the depth to the wet season water table elevation is above or below the 3-foot threshold. The water table elevations for the study areas are shown in Figure 4. 3. Potable Water— Septic tank areas that use private well systems for potable water supply are subject to greater health risks associated with the septic tank effluent being released to the groundwater than those using potable water from a public distribution system. Areas using private well systems were ranked higher than those areas using a central water system. The sources of potable water supply for the study areas are shown in Figure 5. 4. Flood Zone— Septic tanks typically do not drain properly when subject to flood conditions. Areas located within the 100-year flood zone (areas subject to a flood elevation with a 1 percent chance of being equaled or exceeded in any given year) were ranked higher than those areas not located within the flood zone. Flood zone areas are shown in Figure 6. 3-1 Mathews Consulting, Inc Section 3 Evaluation Methods and Criteria 5. Proximity to Surface Water— The study areas were evaluated for their proximity to various surface water classifications. There are two classifications of surface water in the District's service area as defined by the Florida Department of Environmental Protection: 1) Class II waters, suitable for shellfish propagation or harvesting; and 2) Class III waters, suitable for recreation, propagation and management of a healthy, well-balanced population of fish and wildlife. Class II waters have more stringent water quality standards than Class III waters. As such, areas located in the proximity of Class II waters were ranked higher than those adjacent to Class III waters. Surface water classifications are shown in Figure 7. 6. Population Density — Areas with higher population density (e.g. more dwelling units per acre) will result in a greater amount of effluent discharge from septic tanks than lower density areas. Land use categories for population densities are defined as follows: Low Density: Less than 2 units per acre Medium Density: 2 to 5 units per acre High Density: Greater than 5 units per acre For the septic tank evaluation, high density areas were ranked higher than low density areas. Population densities for the study areas are shown in Figure 8. 7. Surface Water Management (SWM) Criteria — The South Florida Water Management District (SFWMD) is responsible for regulating surface water management criteria for development areas in South Florida. In the last 23 years, the SFWMD design criteria for stormwater management systems has gone through several changes since the adoption of the original Basis of Review through Rule 16K-4035 on May 12, 1977. The following summarizes relevant amendments and effective dates for SFWMD's history of stormwater rule development: • May 12, 1977 Adoption of original Basis of Review for surface water management permit applications within the SFWMD. • January 16, 1978 Amendments to generally address conceptual approval applications and the information requirements applicable thereto (e.g. BMPs, water quality, allowable discharge, excavation depth, side slopes, soil storage, hydrographs, design frequency storm events, rainfall intensity curves). • August 11, 1980 Amendments refined, clarified and expanded the criteria contained in the Basis of Review. 3-2 Mathews Consulting, Inc.

Also amendments to include more stringent SWM criteria (e.g. allowable discharges, • side slopes, dimensional criteria for SWM lakes, operational requirements, new discharge criteria formulas, wet retention/detention water quality, rainfall design curves, above-ground impoundments, nomagraphs for outlet structures, checklist for submittals). .-. %:1;cii diner:::, f j: minor ''._ :..'.t tn prtlra.diirc..' • August, 1995 Environmental Resource Permitting (ERP) rules k became effective and replaced "SWM permits". Amendments included definitions for various types of wetlands, limitations to exceptions, and minor revisions to surface water management criteria. The critical dates for surface water management criteria are 1978, when the first set of detailed standards were established for permitting applications, and 1987, when the criteria was substantially modified to included more stringent standards. Areas constructed after 1987 would have been subject to the more stringent SWM standards, and thus, would have better drainage for septic tank performance. Areas constructed prior to 1978 would not have been subject to any SWM standards, are potentially poorly draining areas and thus are rated higher than areas constructed in 1987 or later. Surface water management criteria for the study area are shown in Figure 9. 3-3 Mathews Consulting, Inc.

The study areas have been naked, ith the highest numerical rating indicating the htghect hr iRh hazard rick [he cnidy 7ai'uic J Study Area Ranking Ranking Study Area 4 8, 11 1I 7, 12 • According to the evaluation, the study areas with the highest ranking are recommended for sewering prior to areas with lower rankings. Figure 10 presents an implementation schedule for the LRECD Septic Tank 2002 plan. It is recommended that at the time of implementation, areas excluded from the study (as listed in Section 2) should be re-evaluated to determine the feasibility of adding those areas to the implementation schedule. As previously noted, developments for Study Areas 3, 4, and 5 have been grouped according to several technical factors (e.g. proximity to river, soil type, etc.). However, these areas have significantly different densities. The feasibility of sewering these areas as currently grouped chnuld he further evaluated based on uther considerations, including political and economic factors. All areas represent residential development with the exception of Area 11, which is comprised of the Tony Penna Industrial Area. The type and quantity of discharge from this area may warrant an accelerated schedule due to higher waste load allocations and the potential need to incorporate the area's industrial users into the District's State-approved Industrial Pretreatment Program.

This is a sloping to very steep, excessively drained, sandy soil that formed in dominantly sandy material excavated from canals and deposited along the banks. The water table is below a depth of 6 feet. Permeability is very rapid, and the soil rating for septic tank drainfield is severe. • AU — Arents-Urban land complex. This complex consists of nearly level, somewhat poorly drained, sandy soils and Urban land. The soils formed in thick layers of sandy fill material that were placed over low, wet mineral soils to make the areas suitable for urban • use. This complex is about 60 to 75 percent Arents and 25 to 40 percent Urban land. Arents consist of lawns, vacant lots, golf courses, undeveloped areas, and other open • land. Urban land consists of areas covered by streets, sidewalks, parking lots, buildings, and other structures. The water table is generally 2 to 4 feet below the surface. The soil material is generally rapidly permeable in all layers. The soil rating for septic tank drainfield is severe. • BM — Basinger and Myakka sands, depressional. These are nearly level, very poorly drained, sandy soils in shallow depressions. The depressions are small to large isolated ponds or poorly defined narrow drainageways that have many branches. The water table is above the surface for 3 to 9 months or more in most years. Permeability is rapid, and the soil rating for septic tank drainfield is severe. • Im — Immokalee fine sand. This is a nearly level, poorly drained, deep, sandy soil that has a dark colored layer below a depth of 30 inches that is weakly cemented with organic matter. Under natural conditions, the water table is within 10 inches of the surface for 2 to 4 months during wet periods, within 10 to 40 inches for 8 months or more in most years, but it is below 40 inches in dry periods. Permeability is very rapid, and the soil rating for septic tank drainfield is severe. • Mu — Myakka-Urban land complex. This complex consists of Myakka sand and Urban land. About 25 to 50 percent of the complex is covered by streets, sidewalks, driveways, houses, and other structures. About 40 to 65 percent of the complex consists of open land, such as lawns, vacant lots, and playgrounds. These drained areas are made up mainly of nearly level, poorly drained Myakka sand which has been modified in most places by spreading about 12 inches of sandy fill material on the original surface. The water table is within 12 inches of the surface for most of the year. Permeability is rapid, and the soil rating for septic tank drainfield is severe. A-1 Mathews Consulting, Inc. _ • Attachment A Soil Association Descriptions • PbB — Palm Beach-Urban land complex. This complex consists of Palm Beach sand and Urban land. About 50 to 70 percent of the complex is open land, such as lawns, vacant lots, and undeveloped areas. These areas are made up of nearly level to sloping, excessively drained, Palm Beach sand that has been graded and leveled in many places for urban development. The water table is below a depth of 6 feet. Permeability is very rapid, and the soil rating for septic tank drainfield is slight. • PcB — Paola sand, 0 to 8 percent slopes. This nearly level to sloping, excessively drained, deep, sandysoil has yellowish layers beneath the white subsurface layer. The water table is below a depth of 6 feet. Permeability is very rapid, and the soil rating for septic tank drainfield is slight. • 86 — Paola sand, 8 to 20 percent slopes. This strongly sloping to moderately steep soil is excessively drained. It is on the coastal ridge. Areas range from about 10 to 100 acres. The available water capacity is very low, and permeability is very rapid throughout the profile. The water table is below a depth of 6 feet at all times. The soil rating for septic tank drainfield is slight. • Pg — Placid fine sand. This is a nearly level, very poorly drained, deep sandy soil that has a thick, dark colored surface layer. This soil is on depressed areas and in poorly defined drainageways. Under natural conditions, the water table is within 10 inches of the surface for more than 6 months during most years. Depressed areas are covered with water for more than 6 months. Permeability is very rapid, and the soil rating for septic tank drainfield is severe. 1- • PhB — Pomello fine sand. This is a nearly level to gently sloping, moderately well drained, deep, sandy soil that has a dark, weakly cemented layer below a depth of 30 inches. This soil is on low ridges and knolls. Under natural conditions, the water table is within 24 to 40 inches for 1 to 4 months during wet periods. Permeability is rapid, and the soil rating for septic tank drainfield is severe. • QAB — Quartzipsamments, shaped. This mapping unit consists of nearly level to gently sloping, well drained, deep, sandy soils in areas where natural soils have been altered by cutting down ridges and spreading the soil material over adjacent lower soil, by filling low areas above natural ground level, and by filling and shaping soil material to form golf courses. The water table is below a depth of 60 inches. Permeability is very rapid, and the soil rating for septic tank drainfield is slight. • Sa— Sanibel muck. This is a nearly level, very poorly drained, deep, sandy soil that has a thin organic layer on the surface. This soil is in depressions, drainageways, and broad flats that are transitional to the organic soils in the Everglades area. Under natural conditions, the water table is within 10 inches of the surface for 6 to 12 months in most years. Water covers the surface 2 to 6 months during wet periods. Permeability is rapid, and the soil rating for septic tank drainfield is severe. • 14 — Satellite Variant sand. This deep, nearly level sandy soil is moderately well drained. It is on slightly elevated ridges and knolls in the flatwoods. Areas range from A-2 Mathews Consulting. Inc. [ _ •, Attachment A Soil Association Descriptions about 5 to 200 acres. Slopes are smooth to convex and range from 0 to 2 percent. The _ water table is at a depth of 40 to 60 inches for 6 to 9 months in most years. Permeability is very rapid throughout the profile. The soil rating for septic tank drainfield is severe. _ • ScB — St. Lucie sand, 0 to 8 percent slopes. This nearly level to sloping, excessively drained, deep, sandy soil is on long narrow, dune-like coastal ridges and on isolated knolls. The water table is below a depth of 6 feet. Permeability is very rapid, and the soil rating for septic tank drainfield is slight. • SuB — St. Lucie-Urban land complex. This complex consists of St. Lucie sand and I_ Urban land. About 50 to 70 percent of this complex is open land, such as lawns, vacant lots, and playgrounds. These areas are made up of nearly level to sloping, excessively drained St. Lucie soils. In places, these soils have been modified by cutting, grading, or _ shaping for urban development. About 30 to 50 percent of the complex is covered by streets, sidewalks, driveways, patios, buildings, and other structures. The rest of the complex is made up of Paola and Pomello soils. The soil rating for septic tank drainfield is slight. • TM — Tidal swamp, mineral. This is nearly level, very poorly drained, sandy material that supports a dense growth of mangrove trees. It consists of sandy marine sediments that are flooded by salt or brackish water during daily high tides. The water table is above the surface for 3 to 9 months or more in most years. Permeability is rapid in all layers. The soil rating for septic tank drainfield is severe. • Ur — Urban land. This consists of areas that are 60 to more than 75 percent covered with streets, buildings, large parking lots, shopping centers, industrial parks, airports, and related facilities. Other areas, mostly lawns, parks, vacant lots, and playgrounds, are generally altered to such an extent that the former soils cannot be easily recognized and are in tracts too small to be mapped separately. a A-3 Mathews Consulting, Inc.
