2012/2013 Annual Monitoring Plan Report 6/1/2012 5/31/2013 (Year 2) City of Jacksonville/FDOT NPDES Permit EXECUTIVE SUMMARY: Goal I of the monitoring plan is to identify water quality problem areas. This portion of the plan is implemented by the Routine and Intensive tributary programs. Both programs have been implemented since 2002. Routine Tributary Monitoring includes sampling 103 sites quarterly for fecal coliform bacteria and field parameters. Having a long-term dataset is necessary in determining long-term trends, particularly for fecal coliform compliance, which has demonstrated the most dramatic changes. In 2012/2013, the City of Jacksonville continued to play a leadership role in the Lower St. Johns River Tributaries Basin Management Action Plan (BMAP) Working Group. Under the direction of FDEP, this group has developed BMAPs for 25 of the fecal coliform impaired WBIDs in Duval County. A portion of the Tributary Intensive effort this year was comprised of the City of Jacksonville s Tributary I and Tributary II Fecal Coliform Bacteria BMAP monitoring effort. The City is responsible for sampling five fecal coliform impaired WBIDs at 13 stations for the Trib I BMAP; and five fecal coliform impaired WBIDs at 18 sites for the Trib II BMAP. (Some sites have been recently added, deleted, and changed based on decisions by the Working Group). Other Tributary Intensive efforts this year included the Middle Trout River SSAC intensive monitoring and the Ribault River intensive monitoring to help in developing the Bacteria Control Plan. Goal II of the monitoring plan is to assess effectiveness of storm water BMPs. The City has targeted four project areas. The first project, the Upper Deer Creek Regional Wet Detention Pond effectiveness monitoring, has been completed and previously reported in prior reports. The second project, the Cedar River Outfall Regional Stormwater Facility BMP effectiveness study, was completed this year and is summarized in this annual report. The remaining two BMP effectiveness studies will be scheduled in the near future. Water quality data collected through implementation of this monitoring plan is currently located in City of Jacksonville Access databases. These databases are partially formatted for annual upload to FDEP/STORET databases. This monitoring plan will be reviewed for changes to improve the plan as required in year four. 2

2012/2013 Annual Monitoring Plan Report 6/1/2012 5/31/2013 (Year 2) City of Jacksonville/FDOT NPDES Permit INTRODUCTION The City of Jacksonville, FDOT, City of Atlantic Beach, and City of Neptune Beach submit the following 2012/2013 annual monitoring plan report to fulfill the NPDES Permit monitoring requirement. This monitoring plan report is being submitted as required under Part V.B. of the NPDES MS4 permit. The monitoring plan was approved by the Department on March 5, 2004 with modifications approved on January 17, 2006. GOALS AND OBJECTIVES OF STORMWATER MONITORING The goals and objectives of this Monitoring Plan are to assess the effectiveness of the Stormwater Management Program (SWMP) and the associated pollutant reduction from MS4 systems to the waters of the state to the maximum extent practicable (MEP); also, to evaluate load reductions that have occurred and to identify local sources where urban stormwater is adversely affecting surface water resources. The monitoring plan will be revised in Year 4 to better meet these goals and objectives. To accomplish the goals and objectives of this monitoring plan the City of Jacksonville is integrating three different water quality efforts. Those programs are: 1. The City of Jacksonville s Routine Tributary monitoring program. 2. The City of Jacksonville s Tributary Intensive monitoring program (Tributary Fecal coliform BMAP I, and Tributary Fecal Coliform BMAP II monthly monitoring). 3. The City of Jacksonville proposes to document the effectiveness of four different stormwater pollution reduction measures located in four different sub-basins. SPECIFIC MONITORING GOALS The focus of our monitoring plan is to address two of the three possible Specific Monitoring Goals discussed in the General Guidance and Watershed Considerations for Preparing Stormwater Monitoring Plans as Required for Municipal Separate Storm Sewer System (MS4) Permits document provided by FDEP. 1. Identify potential water quality problem areas related to stormwater runoff that can be targeted for corrective action, retrofits or non-structural BMPs. This monitoring goal will be achieved through the City of Jacksonville s two ongoing tributary monitoring programs (routine and intensive) previously mentioned. These programs will be described later in the report. 3

2. Measure the effectiveness of the stormwater pollution reduction measures (BMPs) that have been or will be implemented. The City of Jacksonville proposes to document the effectiveness of four different stormwater pollution reduction measures located in four different sub-basins. Those four projects are: Upper Deer Creek, Cedar River Outfall, Pine Forest (New Rose Creek), and Woodland Acres Oakwood Villa (Strawberry Creek). MONITORING PLAN SPECIFICS GOAL I: Identify potential water quality problem areas related to stormwater runoff that can be targeted for corrective action, retrofits or non-structural BMPs. TRIBUTARY PROGRAM (ROUTINE) Objectives The Tributary Program originated back in the 1970s. The program was initiated to assess the water quality impacts that over 300 small wastewater treatment plants (WWTPS) were having on the tributaries of Duval County. In the beginning, tributary monitoring locations were upstream and downstream of the WWTPs. After the elimination (through connection to sanitary sewer) of most of the county s package plants (small WWTPS) water quality monitoring at many of the stations was discontinued. The current Tributary Program has data beginning in 1984 at approximately 105-115 stations scattered throughout Duval County s tributaries. At this time 103 sites are included in the sampling program. Station locations are often near bridges and roadways to facilitate sampling efforts; sites are both above and within tidal influence from the St. Johns River or Intracoastal Waterway. The primary objective of this program is collection of long-term dataset that will enable the City to document water quality trends. 4

Constituents The constituents measured in the Routine Tributary Program are limited to field measurements and fecal coliform bacteria. Field Measurements (multi-parameter water quality instrument): Dissolved oxygen, percent saturation of dissolved oxygen, ph, temperature, salinity and specific conductance. Laboratory Analyses: Both total and fecal coliform bacteria were collected until 1996. For the current program, starting in 1996, laboratory analysis includes only fecal coliform bacteria. Field Observations: Stream depth, secchi depth, air temperature, cloud cover, wind velocity and direction, stream appearance, tidal current, visual oil & grease, canopy cover, stream flow stage, current weather, visual turbidity, rain in last 7 days, rain is last 24 hours. Methodology Field water quality measurements are collected and logged with a multi-parameter surface water quality meter (MANTA2 multiprobe with optical HDO sensor, Archer hand held display). Fecal coliform samples are collected as surface grab samples. Frequency All stations in the Routine Tributary Program are sampled at least quarterly (once every three months). 5

2012/2013 ROUTINE TRIBUTARY PROGRAM DATA: The raw surface water quality data collected for this report can be found in Table 12 near the end of this report. DISCUSSION OF ROUTINE TRIBUTARY PROGRAM RESULTS Water Quality Trends Routine Tributary water quality trends for calendar years 1990 through 2012 are plotted in Figures 1 through 7. Each data point is for a full calendar year; therefore no 2013 data is used. Figure 1 charts the percent compliance of six major drainage basins with the State standard for fecal coliform bacteria over the past 23 years. The standard used is for the one day maximum of 800 colony forming units/100ml (cfu/100ml), rather than the standard of not to exceed 400 in 10% of samples which is used in the Tributary BMAP documents. The six basins represented in the figures are Arlington River (11 sites), Cedar River (8 sites), Julington/Durbin Creek (9 sites), Ortega River (7 sites), Trout River (13 sites) and Broward River/Dunn Creek (7 sites). Most basins show a long-term improvement in compliance with the fecal coliform standard. Four basins show very significant improvement between 1998 and 2002. These four basins are Arlington, Ortega, Trout, and Cedar. These significant improvements in bacteria compliance may be due to a combination of factors. One of the most likely causes is the regionalization of the many hundreds of small poorly-maintained wastewater treatment plants that formerly discharged partially treated wastewater into the tributaries. The City Of Jacksonville s Regionalization Rule required phase-out of these small treatment facilities into fewer, larger, welloperated facilities with better treatment. Another factor contributing to significant improvement in bacteria levels may be the State-wide requirements for stormwater treatment. For the last 10 years, improvements in bacteria compliance are not as significant. Julington / Durbin Basin shows some improvement for the last two years in fecal coliform bacteria compliance. Arlington River basin shows a very small improvement from 2011 to 2012. Ortega River basin shows a gradual decline since 2009. The Trout River basin shows a slight improvement over last year. The Cedar River basin shows a small improvement this year. And Broward / Dunn basins show a decline for the past two years. 10

Figure 1. 11

Figures 2-7 present fecal coliform and dissolved oxygen (D.O.) compliance with State criteria for each of the same six basins. (The Julington/Durbin Creek system, due to the extensive wetlands in the basin and very dark water has poor compliance with the 5.0 mg/l freshwater D.O. standard; and for this creek system the WQB has graphed actual dissolved oxygen values rather that percent compliance.) Looking at D.O. and bacteria compliance together for each basin, the following can be observed. During the 1990 s, dissolved oxygen compliance was generally better than fecal coliform compliance for the basins evaluated. However, since around 2000, that trend has changed dramatically in the Arlington River basin and Cedar River basin, and somewhat in the Ortega River basin, as bacteria levels have significantly improved. Looking at long-term dissolved oxygen trends, most basins show no clear trends, either improving or declining. The exception may be a slight long-term decline in D.O. compliance for the Ortega River basin. For the short term, several basins show a noticeable decline for the last few years. This decline could be partly explained by the drought conditions in Northeast Florida in 2010 and 2011 which reduced flows, water depths, and dissolved oxygen levels. Looking at Figures 2 7 for fecal coliform bacteria trends, considering the entire 23 year record, the data indicate a gradual long-term improvement with compliance with the fecal coliform standard, with the possible exception of Broward/Dunn Basin. For the last year, four basins improved slightly and two basins declined. Looking at Fecal Coliform compliance data for the last 10 years from 2002 to 2012: 1. Julington Creek/Durbin Creek Basin: from a high of 100% compliance in 2002 and 2003, compliance has ranged from 75% to 97%. 2. Arlington River Basin: levels have fluctuated up and down between 55% and 85% compliance. 3. Ortega River Basin: compliance has varied from between 65% to 95%. The last three years have shown slight declines in fecal coliform compliance. 4. Trout River Basin shows a slow improvement since 2004, with current compliance levels at 82%. 5. Cedar River Basin: levels of compliance varied from 55% to 80%. 6. Broward River/Dunn Creek Basin had a steep decline in compliance in 2004. Then this basin has displayed a steady improvement, from a low of 35% compliance in 2004 to 90% compliance in 2012010. It has declined again the past two years. 12

2012/ 2013 Water Quality Data for Jacksonville WBIDs In Table 2 all Water Body ID s (WBID s) monitored by the Routine and BMAP Tributary Programs are ranked by fecal coliform bacteria geometric mean for the June 1, 2012 to May 31, 2013 Cycle 3 Year 2 sample period. For this year s reporting cycle, 27 out of 70 WBIDs, (39 percent) have geometric means that exceed the 800 cfu/100ml one time maximum criteria. This exceedance rate is significantly higher than last year s 17 per cent, which had remained consistent for the past two years. The 800 cfu exceedance rate was 30 percent in 2007/2008. The elevated bacteria levels this year may be attributable to more samples being collected following significant rainfall events. We recognize that bacteria levels increase dramatically after a rainfall event in almost all WBIDs monitored. Table 2 also contains the ranking of all tributaries monitored for this year and the two prior years. Looking at the 10 worst-ranking WBIDs (ten highest fecal geometric means) for three years in a row, only one basin has been in the highest ten category for all three years; this basin is Fairchild Branch. Five basins had significantly different rankings this year. Long Branch and Mill Dam Branch had much poorer bacterial rankings based on the geometric means. Meanwhile Butcher Pen Creek, Christopher Creek, and Craig Creek had significantly better rankings this year than in the past two years. Red Bay Branch Howland Creek 19

TRIBUTARY INTENSIVE PROGRAM In the 2012/2013 reporting cycle the Tributary Intensive work was comprised of the City of Jacksonville responsibilities for scheduled monitoring for two different Basin Management Action Plans (BMAPS) and several special studies. The first BMAP for which the City of Jacksonville has responsibilities for monitoring, is the BMAP adopted for the Fecal Coliform TMDL for the first group of Lower St. Johns River Tributaries. (Trib BMAP I). This BMAP, adopted December 2009 is for ten tributaries all within Duval County. The tributaries or WBIDs covered in this BMAP are: Newcastle Creek (2235), Hogan Creek (2252), Butcher Pen Creek (2322), Miller Creek (2287), Miramar Creek (2304), Big Fishweir Creek (2280), Deer Creek (2256), Terrapin Creek (2204), Goodby s Creek (2326) and Open Creek (2299). The City of Jacksonville has committed to perform the required fecal coliform BMAP monitoring for five of these WBIDS: Newcastle, Hogan, Miller, Miramar and Deer Creeks. The second BMAP in which the City of Jacksonville has responsibility to monitor is for the second group of Lower St. Johns River tributaries (Trib BMAP II). This BMAP, adopted August 2010, covers 15 tributaries in Jacksonville: Blockhouse Creek (2207), Cormorant Branch (2381), Craig Creek (2297), Deep Bottom Creek (2361), Fishing Creek (2324), Greenfield Creek (2240), Hopkins Creek (2266), McCoy Creek (2257), Moncrief Creek (2228), Pottsburg Creek (2265B), Sherman Creek (2227), Trout River downstream (2203A), Middle Trout River (2203), Williamson Creek (2316), Wills Branch (2282). The City of Jacksonville has agreed to monitor in five of these tributaries: Fishing Creek, Deep Bottom Creek, Hopkins Creek, Sherman Creek, and Cormorant Branch. 25

Lower St. Johns River Tributary I Fecal Coliform BMAP Monitoring (Trib BMAP I) Objectives This BMAP, adopted December 2009 is for ten tributaries all within Duval County. The Tributaries (WBIDs) covered in this BMAP are: Newcastle Creek (2235), Hogan Creek (2252), Butcher Pen Creek (2322), Miller Creek (2287), Miramar Creek (2304), Big Fishweir Creek (2280), Deer Creek (2256), Terrapin Creek (2204), Goodby s Creek (2326) and Open Creek (2299). The City of Jacksonville has committed to perform the required fecal coliform BMAP monitoring for five of these WBIDS: Newcastle, Hogan, Miller, Miramar and Deer Creeks. The purpose of the monitoring program is to search for and eliminate sources of bacterial contamination and to measure improvements in fecal coliform levels that may be attributed the various BMAP projects implemented by stakeholders. Constituents As described in the monitoring plan for this BMAP the constituents include: Field Measurements: Water Temperature ph Specific Conductance Dissolved Oxygen (D.O.) Secchi Depth Total Stream Depth Sample Depth Meteorological Data Laboratory Analyses: Fecal Coliform Bacteria Additional field observations include stream appearance, tidal condition, visual oil & grease, and canopy cover. Methodology Field water quality measurements are collected and logged with a multi-parameter surface water quality meter (MANTA2 multiprobe with optical HDO sensor and Archer hand held display) or comparable multi-parameter instrument. Water samples are collected as surface water grab samples. Frequency All City of Jacksonville fecal coliform BMAP sampling is being conducted on a monthly frequency (even though the BMAP document allows some sites to sampled quarterly). When fecal coliform results exceed 5000 cfu/100 ml, follow-up sampling is implemented in an effort to identify a source for the elevated results. All follow-up results are tracked independently and are not entered into STORET. 26

DISCUSSION OF FECAL COLIFORM MONITORING TRIBUTARY I BMAP (Trib BMAP I): The objective of the BMAP monitoring effort is twofold: 1. To track fecal coliform water quality improvements resulting from implementation of a variety of projects within each BMAP WBID, and 2. To identify hotspots and then follow-up with additional sampling and investigations so that new or problematic sources will be identified and corrective measures taken by appropriate stakeholders. Stakeholders including the City of Jacksonville provide FDEP with annual updates on the water quality monitoring, project implementation status, and any corrective actions on a WBID basis. It is beyond the scope of this monitoring report to include those project lists and discussion. The City of Jacksonville s fecal coliform BMAP I monitoring results are summarized in Table 8. In order for a WBID to be considered in compliance by the impaired water rule, no more than 10 percent of the samples may exceed 400 cfu/100 ml. Compliance with the 400 cfu/100 ml standard (not the 800 cfu standard as in Table 7) is displayed in Table 8 which includes the last three years of data separated by year. The ten BMAP I tributaries are some of the worst fecal coliform bacteria impaired WBIDs in the Lower St. Johns River Basin. All of the five BMAP I WBIDs being monitored by the City had exceedances much greater than 10 percent. This year the highest percentage of fecal coliform violations were found in Hogan Creek and Miller Creek at 97% and 89% of samples above 400 cfu/100ml. Newcastle Creek, Deer Creek, and Miramar Creek were all at similar levels of 67%, 64%, and 67%. The highest geometric mean was in Hogan Creek at 2518 cfu/100ml. Newcastle and Miller Creeks were above 1,000 cfu. Looking at three years, for the 2010/2011 reporting year, the worst two BMAP I waterbodies were Hogan Creek and Miller Creek. The following year, the worst WBIDs were Newcastle Creek, Miramar Creek, and Miller Creek. This year s worst WBIDs were Hogan, Miller and Newcastle Creeks. The only improving trend over the 3-year period is the Miller Creek geometric mean. The City of Jacksonville has spent extra efforts studying and investigating these creeks with the most elevated bacteria levels. Hogan Creek and Miller Creek in particular have had successes in discovering and removing sources, as reported in the Tributary BMAP Annual Progress Reports. 34

Lower St. Johns River Tributary II Fecal Coliform BMAP Monitoring (Trib BMAP II) Objectives This BMAP, adopted in August 2010, is for 15 tributaries in Duval County. These 15 WBIDs include: Blockhouse Creek (2207), Cormorant Branch (2381), Craig Creek (2297), Deep Bottom Creek (2361), Fishing Creek (2324), Greenfield Creek (2240), Hopkins Creek (2266), McCoy Creek (2257), Moncrief Creek (2228), Pottsburg Creek (2265B), Sherman Creek (2227), Trout River downstream (2203A), Middle Trout River (2203), Williamson Creek (2316), and Wills Branch (2282). The City of Jacksonville has agreed to monitor in five of these tributaries: Fishing Creek, Deep Bottom Creek, Hopkins Creek, Sherman Creek, and Cormorant Branch. The purpose of the monitoring program is to search for and eliminate sources of bacterial contamination, and to measure improvements in fecal coliform levels that may be attributed the various BMAP projects implemented by stakeholders. Constituents As described in the monitoring plan for this BMAP the constituents include: Field Measurements: Water Temperature ph Specific Conductance Dissolved Oxygen (D.O.) Secchi Depth Total Stream Depth Sample Depth Meteorological Data Laboratory Analyses: Fecal Coliform Bacteria Additional field observations include stream appearance, tidal condition, visual oil & grease, and canopy cover. Methodology Field water quality measurements are collected and logged with a multi-parameter surface water quality meter (MANTA2 multiprobe with optical HDO sensor and Archer hand held display) or comparable multi-parameter instrument. Water samples are collected as surface water grab samples. Frequency All City of Jacksonville fecal coliform BMAP sampling is being conducted on a monthly frequency (even though the BMAP document allows some sites to sampled quarterly). When fecal coliform results exceed 5000 cfu/100 ml follow-up sampling is implemented in an effort to identify a source for the elevated results. All follow-up results are tracked independently and are not entered into STORET. 36

DISCUSSION OF FECAL COLIFORM MONITORING TRIBUTARY II BMAP (Trib BMAP II): As mentioned in the BMAP I Section, the objective of the BMAP monitoring effort is twofold: 1. To track fecal coliform water quality improvements resulting from implementation of a variety of projects within each BMAP WBID, and 2. To identify hotspots and then follow-up with additional sampling and investigations so that new or problematic sources will be identified and corrective measures taken by appropriate stakeholders. The City of Jacksonville s fecal coliform BMAP II monitoring results are summarized in Table 11. As in the discussion for BMAP I results, we have again calculated the percent of samples in each WBID that are greater than 400 cfu/100 ml and the geometric mean for each basin. Once again, all five BMAP II WBIDs being monitored by the City had exceedances greater than 10 percent. The data reveals no real improvements yet between the two years. The worst basin this year was Deep Bottom Creek with 78 % of samples greater than 400 cfu/100 ml and a geometric mean of 887. (This was very similar to last year s results of 80% and 714 cfu). Cormorant Branch had the lowest percent of samples above 400 at 48%. The basin with the lowest geometric mean was also Cormorant Branch with 254 cfu/100 ml. Unlike the BMAP I tributaries, all geometric means for the 5 BMAP II tributaries for both years, are below 1000. Table 11. Tributary Group 2 Fecal Coliform BMAP COJ Data Summary.

ADDITIONAL TRIBUTARY INTENSIVE MONITORING Two additional special projects considered Intensive Monitoring were worked on during the past report year. The Middle Trout River (WBID 2203) was sampled every month for one year (July 2012 to June 2013) at two locations by the City of Jacksonville EQD. Also FDEP deployed two continuous DO sondes for several days each month at these same two locations. This data will be used in the effort to complete a Site Specific Alternative Criteria (SSAC) for the Middle Trout River. Work was accomplished on the Ribault River Bacteria Pollution Control Plan (BPCP). The Walk-the Waterbody was conducted with stakeholders on March 21, 2013. Intensive data collection efforts occurred on three different dates as part of the BPCP effort. The Annual update on the Ribault River TMDL Bacteria Control Plan is included in Part VIII of this Annual Report. Middle Trout River Ribault River Walk-the-WBID 47

GOAL II Measure the effectiveness of the stormwater pollution reduction measures (BMPs) that have been or will be implemented. STORMWATER BMP EFFECTIVENESS To accomplish this monitoring goal the City of Jacksonville proposed to conduct effectiveness monitoring for four separate storm water pollution reduction measures when implemented. The City has completed construction on all four of these projects: Upper Deer Creek, Cedar River Outfall, Pine Forest (completed March 2012), and Woodland Acres (completed October 2009). Upper Deer Creek Regional Stormwater Facility BMP Effectiveness Monitoring The Upper Deer Creek Regional Stormwater Facility monitoring (three phases) was complete and results reported (with the final report by CDM Smith attached) in the last annual report. Cedar River Outfall Regional Stormwater Wet Detention Facility BMP Effectiveness Monitoring The Cedar River Outfall Regional Stormwater wet detention facility was planned by the City of Jacksonville to control the loading of contaminants to the Cedar River. This 14-acre facility is located on the southwest corner of the intersection of Highway Avenue and Cynthia Street, and serves approximately 1,500 acres of tributary area that did not receive water quality treatment. The Cedar River watershed has significant sediment contamination from a number of industrial sites as well as a history of high fecal coliform counts. 48

The Cedar River Outfall Regional Stormwater wet detention facility construction was completed in January 2008. In order to fulfill the requirements of FDEP Grant S-0271, which was used to construct the facility, an integral water quality monitoring program was included as part of the overall project to measure facility function and performance. The completion of the monitoring program occurred in October 2012, under the direction of CDM Smith and the University of North Florida. The results are summarized here and the final report is attached to this annual report. The monitoring program was designed to estimate the long-term removal efficiency for 14 water quality constituents. These constituents included: ammonia, cadmium, chromium, copper, lead, nickel, nitrate/nitrite, orthophosphate, total phosphorous, total Kjeldahl nitrogen, total suspended solids, zinc, oil and grease, and fecal coliform bacteria. A total of nine storm events were sampled, of between 0.5 and 3 inches. The expected removal efficiencies of three parameters are: total suspended solids 68%, total nitrogen 8%, and total phosphorus 23%. The figure below displays the estimated removal percentages for TSS, TN, and TP from the nine sampled storm events. Of the 14 compounds measured, the stormwater wet detention facility reduced the majority of them by a significant amount. The calculated removal efficiencies of TSS, TN, and TP, exceed those that were expected for this facility. The final report for the Monitoring Program for the Cedar River Outfall Regional Stormwater Facility is attached to this report. 49

Cedar River Pond Inflow & Outflow Samples Working at the Cedar River Pond Site Pine Forest and Woodland Acres BMP Effectiveness Monitoring The Monitoring Plan component for stormwater BMP effectiveness monitoirng originally described a fairly simple plan of grab samples collected before and after BMP construction and at upstream and downstream locations. The implementation of the intensive event-based studies at Deer Creek and Cedar River stormwater facilities mandated a very intensive and demanding workload requiring extra equipment, effort, time, costs, and human resources. This demanding workload allowed monitoring at only one project at a time and precluded any monitoring of the remaining two projects. The remote automatic monitoring equipment for the Cedar River pond effectiveness study was removed from the site this year and stored for possible future use at additional sites. The Pine Forest stormwater pond and drainage improvements in the New Rose Creek watershed had construction complete in March 2012. The Woodland Acres Oakwood Villa pond and stormwater drainage improvements in the Strawberry Creek basin had construction complete in October 2009. It is anticipated that the monitoring to assess the effectiveness these two projects will begin in the near future now that the Cedar River BMP effectiveness study is complete. 50
