Cow Pen Slough/Shakett Creek Flood Study Update Section 1 - Introduction

SECTION 1. INTRODUCTION

1.01 Purpose

The Cow Pen Slough/Shakett Creek Flood Study Update (CPSSCFSU) was prepared to ( 1) characterize the existing hydrologic/hydraulic network; (2) identify existing Flood Protection Level of Service (FPLOS) deficiencies; (3) evaluate existing/baseline Pollutant Loads; (4) delineate the existing 100-year/24-hour floodplain to guide future planning and development; and (5) identify significant maintenance needs. It should be noted that the Fox Creek tributary and its associated drainage basin were included in the study area. However, independent analyses and a Basin Master Plan have previously been conducted and adopted by the County for the Fox Creek Basin.

Cow Pen Slough/Shakett Creek Flood Study Update Section I - Introduction

Creek basin is bordered by Phillippi Creek and South Creek to the west, Curry Creek to the south, and the Myakka River watershed to the east. Major tributaries include Fox Creek and Salt Creek. All of these watercourses converge into Shakett Creek at the southern end of the basin. The Cow Pen Slough/Shakett Creek basin is primarily undeveloped but does include some residential communities including Kings Gate Mobile Home Park, Saddle Creek, Saddle Oaks Estates, Gator Creek, Misty Creek, and Heritage Oaks. The basin drains from north to south, ultimately discharging into Dona Bay.

The area east of Interstate 75 consists mainly undeveloped and agriculture lands including the Hi-Hat Ranch, the LT Ranch, Hawkins Ranch, and the Albriton Orange Grove.

As previously indicated, the Cow Pen Slough/Shakett Creek basin discharges into Dona Bay. According to Chapter 62-302.600 of the Florida Administrative Code (F AC) and County Ordinance 72-37, Shakett Creek is categorized as Outstanding Florida Waters (OFW) .

Cow Pen Slough/Shakett Creek Flood Study Update Section 2 - Background

SECTION 2. BACKGROUND

2.01 Historic Perspective and Previous Works

Over the past I 00 years several hydrologic and hydraulic changes have occurred that have altered the magnitude and timing of flows (if not the volume of freshwater) to Dona Bay and Shakett Creek (DBSC). A partial list of some of the major alterations that have occurred over the years is provided below:

Initial 1847 survey maps of Sarasota County indicate that Shakett Creek essentially split into the two branches that are currently known as Fox Creek and Salt Creek. This survey also identify a large low"lying area meandering generally east towards the Myakka River north of these natural creek systems on the original surveys. This would seem to indicate that much of the Cow Pen Slough basin located to the north may have historically "drained" to the Myakka River. This low"lying area is generally located south of what is now the Pinelands Reserve and north of what is now the Lake Awesome RV Park. It is not only still evident on current aerials but fonns a long recognized area where floodwaters may be transferred between Cow Pen Slough and the Myakka River. Interestingly, a review of the 10-year flood elevations computed by the USGS for the Myakka River in the mid-1970's revealed that these elevations would exceed the watershed divide in this location thereby indicating that the Myakka River overflows to Cow Pen Slough. Conversely, the engineering design report for the Blackbum Canal indicates that flood stage elevations were higher on the Cow Pen Slough side of the watershed ridge thereby forcing flows from Cow Pen Slough to the Myak.ka River .

It is suspected that sometime between 184 7 and the 1920' s that the natural Salt Creek was dredged and extended north to this low-lying area to pull water south into RDBSC during low and nonnal flow conditions. This man-made drainage formulated the "old" Cow Pen Slough ditch.

In the 1920's approximately 5,000 acres of the Cow Pen Slough watershed was included in the Sarasota Fruitville Drainage District and diverted to the Phillippi Creek basin. This was accomplished via the extension of Main A through a natural ridge (Tatum Ridge) and the construction of a large earthen dike at the new divide line. This earthen dike still acts as the divide between the Cow Pen Slough and Phillippi Creek basins.

In probably the best documented alteration of the Cow Pen Slough watershed, the Soil Conservation Service constructed a defined and relatively efficient canal from Shakett Creek north to the extension of Bee Ridge Road. This project was in response to severe flooding which occurred almost annually between 1957 and 1962 causing significant flood damage to agricultural operations in both the Phillippi Creek and Cow Pen Slough Basins. Initiated in the early to mid l 960's and continuing into the early l 970's, the work was halted due primarily to concerns over environmental impacts to Dona Bay. Work completed, included approximately 14 miles of a main canal and 3 water level control structures. However, the northern most structure has essentially never been operational as flood waters resulted in a bypass wash out soon after its construction. Later phases of the project, which were either never completed or never initiated, included the construction of a stonnwater pumping station to re~ direct floodwaters from Phillippi Creek and the South Creek lateral system. These remaining

projects were officially abandoned by action of the Sarasota Board of County Commissioners in 1979. It is important to understand that the design of this canal system was not to alleviate flooding but reduce the duration of inundation on adjacent fann and pasture areas. Specifically, the design was intended to remove approximately 5.13 inches of runoff within a 24-hour period, equating to 0.22 cfs/acre. Even if the project had been completed, farm areas would have been inundated between 18 and 26 hours and pasture areas would have been inundated between 3 and 5 days, depending on the amount of rainfall. The original design also provided for periodic gaps in the spoil banks to allow for the expansion of floodwaters into the adjacent, historical floodplain. A review of a previous investigation of Cow Pen Slough by the Southwest Florida Water Management District in 1981 concluded that the canal work that was completed probably did not significantly alter the volume of freshwater to DBSC. However, this same report provides evidence that the canal did significantly alter the timing and magnitude of flood flows to DBSC.

In the mid-1980's, a large orange grove was constructed within one of the most significant floodplain areas of Cow Pen Slough. To provide the necessary pre-requisite drainage for the orange grove operation, a large dike/levee was constructed around the perimeter of the grove to isolate it from the Cow Pen Slough floodplain and stormwater pump stations were constructed within the grove to evacuate stormwater into the adjacent Cow Pen Slough canal.

In the early to mid 1990's, Sarasota County purchased and made several alterations to a large tract of land in the Cow Pen Slough basin currently referred to as the Pinelands Reserve. Although the land was purchased primarily to construct a landfill operation for the County, much of the land was set aside in its natural state. Hydrologic alterations associated with the Landfill construction include the construction of an elevated access road along the east side o f the Cow Pen Slough canal and the enhancement of a large group of wetlands within the Pinelands Reserve by the placement of fixed weirs. The original SCS metal pipe, drop structures located within the Pinelands Reserve on the west side of the canal were replaced with large concrete inlet boxes.

Finally, it should be noted that numerous borrow pits have been constructed in the south central portion of the Cow Pen Slough watershed, east of the canal. Primarily associated with mining activities, some of the pits have subsequently been incorporated into land development activities such as the Lake Awesome RV Park.

2.02 Existing Flooding

Areas that have historically been susceptible to flooding typically correspond to soils defined as either depressional or frequently flooded by the Sarasota County Soils Survey. Most of the rural estate development that has taken place of in the Cow Pen Slough B;lsin has occurred landward and along the fringe of these historical low-lying areas. Some encroachment of the low-lying fringe has taken place north of Clark Road. The existing conditions 100-year floodplain is presented on Exhibit 3 .

2.03 Prior Studies

The Cow Pen Slough basin has been the subject of several previous authoritative studies. A list and brief descriptions of these previous studies is provided below:

1. 1985 - Floodplain Management Study - Cow Pen Slough Watershed

This study was prepared by the Natural Conservation Resource Service (flea the Soil Conservation Service). Indicated a basin area of approximately 77 square miles. The study was limited to the main Cow Pen Slough canal from Laurel Road to State Road 780 (Fruiteville Road). The steady-state step backwater model (WSP-2) used did not consider routing effects and volumetric limitations. The report was never adopted by Sarasota County or FEMA.

2. September 1997 - Cow Pen Slough - Basin Master Plan, Final Report

In 1995, Sarasota County authorized the Natural Resource Conservation Service (fka the Soil Conservation Service) to conduct the Cow Pen Slough Basin Master Plan. This study considered the Cow Pen Slough Basin north of its confluence with Fox Creek. The Salt Creek tributary and its associated drainage basin were incorporated into the study but Fox Creek and Shakett Creek were not included. As such, the study included approximately 64.2 square miles. The hydrodynamic UNET stormwater model was used for the analysis.

SECTION 3. EXISTING CONDITIONS ASSESSMENT

3.01 Flood Protection Level of Service Objectives

The flood protection level of service (FPLOS) objectives applied to the Cow Pen Slough/Shakett Creek basin are based upon those adopted by the Sarasota County Comprehensive Plan. Table 3.01 presents the FPLOS standards for Sarasota County.

To quantify the existing FPLOS deficiencies in the Cow Pen Slough/Shakett Creek basin, a detailed hydrodynamic computer model was first developed to predict flood elevations throughout the watershed. Version 2.2 of Interconnected Pond Routing (ICPR) software was used to model the watershed. The Cow Pen Slough watershed has been represented in the model by 1519 subbasins, 1621 nodes, 4 71 pipes, 404 channels, 1668 weirs, 162, drop structures, 19 bridges, and 6 rating curves/operating tables corresponding to stormwater pumps. An overview of the modeling parameters is presented below.

For a complete discussion of the modeling methodology, please refer to the Phillippi Creek Basin Master Plan Update. Information from the SCS Cow Pen Slough Basin Master Plan was reviewed and incorporated into the updated model, as applicable. The original as-built engineering drawing were also reviewed in detail and used to construct the updated model. In addition, extensive field surveying was conducted to establish the existing stonnwater conveyance system. Copies of the computer input as well as the node-reach diagram are available in digital format upon request from the Stonnwater Utility. A copy of the basin/subbasin map is provided herein as Exhibit 1. The node/reach diagram is presented on Exhibit 2.

The computed flood elevations were then used to delineate the horizontal limits of the 100-year floodplain on Southwest Florida Water Management District (SWFWMD) 1-foot contour interval aerial maps. Structures and roadways, which fell within the horizontal limits of the floodplain, were inventoried as potential FPLOS deficiencies. Roadway FPLOS deficiencies were determined by comparing roadway spot elevations on the SWFWMD aerials (or, if available, engineering roadway plans) to the computed flood levels. Finished floor elevations of structures horizontally located in the 100-year floodplain were field surveyed to determine those that constitute FPLOS deficiencies (i.e. have their finished floor elevation below the flood stage).

3.01.1 Results

The results of the existing conditions assessment did not indicate any existing structure FPLOS deficiencies in the Cow Pen Slough/Shakett Creek basin. However, several street segments are susceptible to flooding in excess of the FPLOS criteria. Exhibit 3 identifies the horizontal limits of the 100-year floodplain. The existing FPLOS deficiencies are inventoried in Table 3.01.1 below .

It is noted that flood elevations are not provide for Bern Creek Loop. Although SWFWMD topographic aerials were not available for the Bern Creek area while this flood study update was being perfonned, it is expected that flooding of this street constitutes a flood protection level of service deficiency. SWFWMD has subsequently completed topographic aerials for the Bern Creek area, which should be incorporated into a future update to the Cow Pen Slough model. Flood elevations and the degree of flooding for Bern Creek Loop should be quantified as part of this future update.

3.02 Water Quality

The Natural Resource Conservation Service (NRCS) as part of the original Basin Master Plan Report computed Stormwater runoff pollution due to non-point sources for the Cow Pen Slough basin. The NRCS used the Watershed Management Model (WMM) developed by Camp Dresser & McKee (CDM) as part of the Sarasota County National Pollutant Discharge Elimination System (NPDES) program for stormwater discharges. The model uses a spreadsheet format to estimate annual non-point source loads from direct runoff based upon runoff volumes and event mean concentrations (EMCs). The EMC is defined as the total pollutant discharged during the storm divided by the total runoff volume.

3.02.1 Pollutant Loading Results

A summary of the model output for the conventional non-point source conventional pollutants, nutrients, and metals for existing conditions is listed in Table 3.02.1. The gross pollutant load reflects the total estimated amount of pollutant load that is generated in the basin. However, the gross pollutant load does not reflect the total amount of pollutant that actually is discharged from the basin because a portion of it is retained in

Cow Pen Slough/Shakett Creek Flood Study Update Section 3 - Existing Conditions Assessment

the existing stormwater treatment facilities and wetlands. Net annual pollutant load, as presented in Table 3.02. l, is defined as the amount of estimated pollutant discharged into the final receiving waterbody. Net load calculations take into account the mitigating effect of non-structural stormwater management practices in the developed areas.

The non-point source pollutant load calculations are based strictly on land use configuration and the estimates have not been calibrated with actual sampling data. However, the results can be used to indicate the location of areas where runoff pollution control measures would be more effective.

The Sarasota Bay National Estuary Program (SBNEP) established Pollutant Load Reduction Goals (PLRGs) of7% for nitrogen and 27% for metals. However, since Dona Bay is located just south of the SBNEP study area, these PLRG's may not apply. Dona Bay and the Cow Pen Slough watershed were included in the Charlotte Harbor National Estuary Program. PLRG's and Total Maximum Dailey Loads TMDL's for the CHNEP are to be determined as part of the Charlotte Harbor National Estuary Program between 2002 and 2006.

In the meantime, any new development within the is required to include stormwater treatment facilities to mitigate potential increases in pollutant loads as required by the SWFWMD and Sarasota County Land Development Regulations. Any future capital improvement project to address FPLOS deficiencies will also need to consider incorporating stonnwater treatment components into its design.

Cow Pen Slough/Shakett Creek Flood Study Update Section 4 - Conclusions and Recommendations

SECTION 4. CONCLUSIONS AND RECOMMENDATIONS

4.01 Delineation of Existing Floodplain

As part of the Cow Pen Slough Flood Study Update, the limits of the I 00-year riverine floodplain have been identified and mapped consistent with FEMA's designations as shown on Exhibit 3. It should be noted that the FEMA "AE" zones, identified in dark blue, correspond to areas in the l 00-year floodplain typically associated with moving and/or deep water while FEMA "AH" zones, identified in light blue, correspond to areas of ponding, as defined by FEMA, where average depths are between I and 3 feet. Exhibit 3 identifies these two zones, reflecting these differing floodplain functions that are recognized by FEMA. Adoption of the Cow Pen Slough Basin Master Plan will assure that these floodplain areas will be recognized and that the floodplain functions will be preserved when new development proposals are considered. In addition, the detailed stormwater model developed as part of the Basin Mater Plan Update provides a valuable tool to evaluate the effects of proposed land use changes.

It is recommended that the Cow Pen Slough model update be utilized as a basis of review to evaluate proposed development and drainage modifications so that potential adverse increases in off-site flood stages are adequately mitigated. In addition, it is recommended that finished floor elevations be set a minimum of 2 feet above the 100-year flood elevations computed by the Cow Pen Slough flood study update, if such elevations are higher than the base flood elevations contained on the current Flood Insurance Rate Maps.

4.02 Preliminary Investigation of Existing FPLOS Deficiencies

As indicated previously in Section 3, several existing street FPLOS deficiencies exist in the Cow Pen Slough and Shakett Creek basins. These street FPLOS deficiencies are identified as green diamonds on Exhibit 3. A preliminary investigation of these level of service deficiencies was conducted and is presented below:

Cow Pen Slough - Public Roads

The flood study update indicates that Fruitville Road, a major arterial, is subject to flooding in 2 locations. This flooding is only expected to occur for the 100-year design storm. Flood levels on the south (downstream) side of Fruitville Road are predicted to be at approximately at the same elevation as the edge of pavement of Fruitville Road. Therefore, minimizing culvert/bridge headlosses at these 2 locations would move toward resolution of these FPLOS deficiencies. Adverse increases in downstream flood stages would need ,to be considered under this alternative. A second alternative would be to look at elevating Fruitville Road. However, this alternative would create a diking effect that can be expected to impound more water north ofFruitville Road. Several private roads just north ofFruitville Road currently do not meet FPLOS standards and would be further impacted if Fruitville Road were elevated. In addition, several residential structures north of Fruitville Road may be adversely impacted as well.

C:\My Documcnts\CowPcn\scction4.cowpcn.doc Page 4-1


Dove Street and Curlew Road are both local roads located southeast of State Road 72 and north of Hawkins Road. The flood study update indicates that both of these roadways will be subject to flooding in excess of the FPLOS standard, for all design storm events. One potential alternative solution would be to reduce culvert pipe headlosses from Curlew Road to the south side of Hawkins Road. This would potentially require replacing culverts under Curlew Road and Hawkins Road, as well as several driveway culverts on the west side of Dove Street. Potential adverse increases in downstream flood stages associated with this alternative would need to be considered and mitigated.

The flood study update also indicates that Rustic Road will flood in 2 locations in excess of the FPLOS standard. The segment associated with node 093066 in particular should be investigated, as it does not meet the FPLOS criteria for all design storm events. An initial part of this investigation should include a field survey to confirm the roadway profile elevations of Rustic Road. Although the cited edge of pavement elevations (and FPLOS deficiencies) are based upon the SWFWMD contour aerials, a visual site inspection indicated that this roadway might have subsequently been elevated/resurfaced. However, attempts to locate engineering plans to confirm such were not successful. In the event that the field survey verifies the SWFWMD elevations, one potential alternative solution would be to investigate minimizing headlosses under Rustic Road at this location. The flood study update indicates that flood elevations south of Rustic Road are approximately I foot above the lowest edge of pavement for Rustic Road, based upon the SWFWMD aerials.

• Cow Pen Slough - Private Roads

•

King Arthur Drive, Camelot Drive, and Duchess Avenue are all local streets within Kingsgate Club. Kingsgate Club is situated in a recognized flood hazard area and is situated between Cow Pen Slough and Salt Creek. These streets were designed to flood and in fact, a requirement to extend 3 roadway cul-de-sacs to Cow Pen Slough to convey overflows through the development to Salt Creek was part of the original special exception approval process for the project. In addition, it was required that the "no spoil pile" area between Cow Pen Slough and the cul-de-sacs be enlarged to accommodate this movement of floodwaters. However, in recent years this spoil pile between Cow Pen Slough and Kingsgate Club has been reconstructed, presumably to prevent floodwaters from entering. The model for the flood study update (and resulting street flooding in Kingsgate Club) reflects this existing condition. This historical perspective is provided to illustrate that the street flooding in Kingsgate Club could be even greater than what is currently indicated. Re-establishment of the spoil pile to prevent floodwaters from entering Kingsgate Club may not only reduce the degree of street flooding in Kingsgate Club, but may provide for minor increases in flood stages in the adjacent Cow Pen Slough canal without a resulting adverse impact in the Kingsgate Club. ,

The private roads for Kingsgate Club drain to an on-site lake which discharges to Salt Creek, a tidal water body. Therefore, a potential alternative solution to addressing the existing street FPLOS deficiencies would be to allow more water out during peak conditions. Assuming no adverse impact to downstream flood stages, the existing on-site stormwater lake could be retrofitted to enhance water quality. Activities such as the removal of sediment accumulation

in the lake or the installation of aquatic plants for biological assimilation of pollutants are 2 possible options.

Cowpen Lane, Cowpen Road, and Vic Edwards Road are all local roads located just upstream of Fruitville Road. It is possible that these FPLOS deficiencies could be corrected if the FPLOS deficiencies associated with Fruitville Road is addressed.

Finally, Bern Creek Loop is expected to have 3 segments that are subject to flooding and likely constitute FPLOS deficiencies. At the time of the flood study update, topographic maps for this area were not available, so flood elevations computed for this area should be considered preliminary. However, SWFWMD topographic aerials recently became available for this area which would allow for a more detailed and definitive assessment of flooding Bern Creek.

Shakett Creek - Public Roads

The flood study update indicates that a segment of Albee Farm Road, a major arterial, is subject to flooding in excess of the FPLOS standard. This flooding is only expected to occur for the 100-year design storm. This flooding is a result of the flood stage in the stormwater pond for Albee Farm Road exceeds the road's low edge of pavement. However, the flood level in the receiving watercourse (canal 19-125) is at the approximate elevation of the low edge of pavement. An increase in the permitted discharge from the roadway pond would be required to reduce the pond and roadway flooding .

Based upon the flood study update Orange Grove A venue, Pine Street, and Maple Street are all local roads that experience flooding in excess of the FPLOS standard during the 10-year design storm. These roads cross the same watercourse that receives discharges from the Albee Farm Road stormwater pond. Two (2) residential structures and a footbridge also span this watercourse. While the residential structures due not appear to cause a restriction, the footbridge does create a notable amount of headloss. Crossings along this watercourse, including the restrictive footbridge, need to be re-evaluated to reduce flood stages to acceptable levels. Although it is not expected that removing restrictions along this watercourse would have an adverse impact on downstream flood stages, some water quality enhancement measures should be considered in the design since this watercourse discharges directly to the tidal waters of Shakett Creek.

The flood study update also indicates that Aquila Street, Bonito Avenue, and Dona Bay Way experience flooding excess of the FPLOS standards. These local roads all traverse an unnamed watercourse that drains to canal 19-123. Restrictive culverts along this watercourse should be re-evaluated to reduce flood stages to acceptable levels.

Shakett Creek - Private Roads

Based upon the flood study update, Truman Street is the only private road with flooding in excess of the FPLOS standards. Located within the Laurel Woodlands subdivision, it is only subject to excessive flood depths for the 100-year design storm. This FPLOS deficiency

Cow Pen Slough/Shakett Creek Flood Study Update Section 4- Conclusions and Recommendations

could likely be addressed by increasing the capacity of the equalizer culvert between this roadway and the downstream stonnwater pond.

It is recommended that detailed alternative analyses be conducted to address the public roadway FPLOS deficiencies. Specifically, it is envisioned that 5 areas would need to be evaluated.

First, the area in the vicinity of Fruitville Road should be evaluated to address the flooding of Fruitville Road. The analyses should incorporate the SWFWMD topographic information for the Bern Creek area that is now available. Primary benefits of various alternatives relative to addressing the flooding of Fruitville Road should be weighted against the estimated cost. Secondary benefits to adjacent private streets should be also considered, qualitatively.

The second area that should be subjected to alternative analyses is the drainage system along the west side of Dove Street between Curlew Road and Hawkins Road. The estimated cost of addressing these FPLOS deficiencies should be compared to the associated benefit, and to the extent possible, defrayed with stormwater maintenance funds. Adverse impacts in flood stages that might result should be mitigated and opportunities for water quality enhancement should be considered with any alternative.

The third area the needs further investigation and possibly alternative analyses is the Rustic Road area. As previously indicated, a field survey should initially be performed to confirm that the elevation of this roadway is indeed as low as indicated on the SWFWMD topographic maps. If this is confirmed, alternatives to address these FPLOS deficiencies should be evaluated. The estimated cost of addressing these FPLOS deficiencies should be compared to the associated benefit, and to the extent possible, defrayed with stormwater maintenance funds. Adverse impacts in flood stages that might result should be mitigated and opportunities for water quality enhancement should be considered with any alternative.

The fourth and fifth areas that should be subjected to alternative analyses are located in the Shakett Creek basin. They include the watercourses associated with canal 19-123 and canal 19-125. The estimated cost of addressing these FPLOS deficiencies should be compared to the associated benefit, and to the extent possible, defrayed with stormwater maintenance funds. Adverse impacts in flood stages that might result should be mitigated and opportunities for water quality enhancement should be considered with any alternative.

It should also be mentioned that complaints of drainage being adversely impacted as a result of activities with the Central County landfill site have been received from numerous, adjacent private property owners. These complaints go back over the past several years and have prompted Sarasota County Solid Waste in association with Sarasota County Natural Resources to investigate the validity of these complaints utilizing the Cow Pen Slough model developed as part of this flood study update. This investigation is to be perfonned by Stormwater Management Resource Technologies, Inc. under separate agreement.

4.03 Future Development/Regional Stormwater Facilities

Although the Flood Study Update has identified existing FPLOS deficiencies, it also affords the opportunity to plan for the future. The Sarasota County Land Development Regulations encourage the use of regional stormwater

At this time Sarasota County has no formal process to develop or to provide incentives for regional water resource facilities. Accordingly, such a proposal would need to be privately initiated in the meantime.

4.04 Long Term Maintenance

As previously indicated, the primary drainage system for the Cow Pen Slough basin is the canal constructed in the late I 960's by the SCS. This canal can be thought of as the main artery to the Cow Pen Slough basin. The drainage works completed by the SCS included the Cow Pen Slough canal, 3 major water level control structures, 32 metal pipe/riser structures, and 46 breaches in the adjacent spoil pile/levee. Exhibit 4 presents the structure and breach locations for reference. According to the original SCS plans, the canal is located within a 160' wide public drainage easement with 100' x 20' public drainage easement stubs corresponding to the riser structure locations. The public easement agreement with underlying private property owners was granted in consideration of maintenance and operation being performed by Sarasota County. An evaluation of maintenance needs was performed with respect to 3 elements of the Cow Pen Slough canal - sediment accumulation in the main canal, replacement/repair/modification of the metal riser structures, and gated water level control structure repair/removal.

4.04.1 Sediment Accumulation

The Cow Pen Slough canal system was designed as a wet canal with gated water level control structures. The gated structures/weirs control water levels in the canal to a depth of approximately 5 feet. This design is effective in reducing design velocities so that the flood profile is flattened and sediment is deposited in the canal, upstream of the weirs. If properly maintained through periodic and routine sediment removal, such a system should be capable of minimizing sediment loads to the receiving water body, which in this case is Shakett Creek and Dona Bay.

A comparison of the original 1962, SCS "as-built" canal invert for the Cow Pen Slough canal and the surveyed canal cross-sections, obtained in the past several years, indicated between 2 and 7 feet of sediment accumulation. Discussions with County stonnwater and drainage operations staff indicated no recollections of sediment removal activities in the past 40 years.

To assess the effects of this sediment accumulation on flood stages, the canal cross sections for the existing conditions Cow Pen Slough model were revised to reflect the original design conditions. Simulations for the 2-year and I 00-year design storms were perfonned. And resulting flood stages were then compared to existing flood stages. Exhibit 5 visually presents areas within and along the canal where the sediment removal would reduce flood stages

approximately 3 inches or more for the IOO-year design storm. Similar reductions were indicated for the 2-year design storm.

It is recommended that the sediment accumulation in the Cow Pen Slough canal be removed as part of a routine maintenance program. Since the Cow Pen Slough basin is contained in the stormwater maintenance service area, it would seem appropriate to use stormwater maintenance revenue to perform this activity. However, preliminary discussions with Central County Landfill personnel indicate that they may be in a position to utilize this material in the near term. This may help to defer maintenance cost associated with the sediment removal. Regardless, it is also recommended that core samples of the sediment accumulation be taken periodically to determine both the suitability of the material for landfill cover and to determine the nutrient and heavy metal content on the sediments, if any. The latter is recommended to help quantify any water quality benefits that could be associated with removal of theses sediments in terms of potential nutrient and metal pollutant load reductions.

4.04.2 Riser Structure Replacement/Repair/Modifications

As previously indicated, the original "as-built" plans for the Cow Pen Slough canal included over 30 metal pipes to accommodate drainage from lands adjacent to the canal. These structures are contained within public drainage easements and are located on Exhibit 4. In addition, Table 4.04.2 was prepared to provide an inventory of these structures. Column 1 of Table 4.04.2 identifies the structure number corresponding to that on Exhibit 4. Also, below each structure number in column 1 is the corresponding "from" and "to" nodes for each structure in the Cow Pen Slough/Shakett Creek model, as referenced on Exhibit 2. Column 2 identifies the pipe size from the original "as-built" plans in the first row and existing pipe sizes, as field verified/surveyed in subsequent rows. Similarly. Column 3 inventories the "asbuilt" and existing pipe lengths. Columns 4 and 5 present an inventory of the upstream and downstream pipe inverts based upon the "as-built" plans and the filed verification survey. Columns 6 tltrough 8 present similar "as-built" and field survey information for the riser structure, as applicable. Column 9 indicates if the structure has a flapper gate on the downstream end of the pipe, to prevent backflow. Finally, column 10 provides the field survey reference. as applicable .

Based upon a review of this information, few of the riser structures are currently in their original operative condition. Some structures are missing entirely, many are rusted and in disrepair, some have been replaced and elevated with concrete inlet boxes, and additional pipes have been added, particularly north of Clark Road.

Of immediate priority, it is recommended that missing structures 19 and 20 be replaced. Also, the riser inverts and widths for structures 4, 5, 7, 8, and 11 should be restored to their original "as-built" condition by cutting notches in the existing concrete inlet boxes, as soon as possible. Other structures that should be restored or replaced in accordance with the original "as-builts" over the next several years include structures 3, 12, 17, 18, and 29. Structures 6, 9, and 10 are located on the east side of the Cow Pen Slough canal in the Pinelands Reserve. Previous modifications to these structures are to be evaluated under a separate study. Structures 13, 15, and 16 have been replaced by, and are currently being maintained by the Albriton Orange Grove operation. The remaining structures should be inspected annually for maintenance or replacement needs.

4.04.3 Gated Water Level Control Structure Replacement/Removal

A recent inspection of water level control structures I and 2 indicate that the gates have become badly rusted and are in need of replacement. As previously indicated water level control structure 3 has never been operational. This structure should be removed.

It is recommended the gates for water level control structures 1 and 2 be replaced. Control structure number 3 should be removed.
