Storm Drain Filters
The City of Dana Point reported that their storm sewer filters have trapped over 50 tons of material to date. They also reported that every month 10 to 30 tons of material is being picked up during street sweeping.
The County of Orange has installed filters in storm drains at Dana Point Harbor. Some may not be in yet in all drains.

Action: Richard Haimann of County of Orange Watershed and Coastal Resources to request information from County of Orange Operations, regarding which filters have not yet been installed and when they will be installed and report at next meeting.

AB 411 Monitoring
County of Orange Public Health shared microbiological sampling data. The data suggested exceedences from sampling stations around Baby Beach. It was noted that samples were typically collected from upper 12 inches of water when collected in deeper waters.
Dana Point city officials stated that the waterfall drain (where exceedences were observed) is from a private community. Upland of the private community are some city properties - namely restaurants, who have been observed to wash down outside before code enforcement hours.
Richard Gardner made a statement regarding high water clarity, presence of fish, and the lack of visible benthic vegetative growth.
Residents of Dana Point discussed the practices of pet owners at the Headlands bluff above Baby Beach. It was stated that pet owners tend to not pick up pet litter at that location. City of Dana Point stated that Headlands development will occur and the developers have agreed to put in "state of the art" stormwater management facilities.

Entre-Manure has is in the business of collecting and disposing of dog litter. They have a contract with Laguna Beach and have collected 160 lbs. of dog waste in four collections from two locations in Laguna Beach.

Dana Point officials stated that there is an ordinance in City of Dana Point to clean up after your pet. Violations are $50 citations. There is a $211 citation for a leash ordinance violation.

City Officials stated that Dana Point has a public education program - one item in the public education program regards the necessity to pick up after one's pet.

Ocean Institute
Dan Gee spoke about the Ocean Institute's constr`uction progress. Ocean Institute has been under development for the past three years. Dan Gee started about a year ago. They were about to start construction and were about $2M over budget. They also had a very environmentally sensitive and sustainable design. All lumber was specified as farm grown. The heating coils under the building required no fuel combustion. The stormwater was to run through vegetated infiltration zones and a storm receptor that would spin out and remove debris before discharging into the Baby Beach area. They needed the $2M to proceed forward. They picked 173 items to redesign in order to reduce costs. They were able to meet their budget without raising additional funds. One of the most significant changes was the parking lot paving system. The original design called for crushed decomposed granite for the parking lot, through which stormwater would infiltrate. They discovered that the underlying soils had permeabilities too low to allow infiltration. Additionally the decomposed granite was of very high cost. They redesigned the pavement system as asphalt. They retained stormceptor concept and designed vegetated infiltration basins in border and inter parking areas that drain into a storm sewer. The stormceptor is at the lower reach of the storm sewer main. They proceeded with construction with that design. They route upland stormwater around the parking lot to the storm receptor.

Ocean Institute will monitor the performance of the storm drain system. The parking lot will be functional. As they monitor the stormwater system progress, they will work to try to implement systems that solve stormwater and harbor problems related to the location of Ocean Institute.
County of Orange stated that they would monitor the performance of the Ocean Institute stormwater collection system for its impact on the harbor water quality. County stated that they have not yet developed the monitoring plan, but are in the process of doing so.

City of Dana Point suggested that during County monitoring of Ocean Institute stormwater system, upstream testing in the curb to the north of the facility that will capture run-on be monitored to determine what is coming from upland areas and what is generated at the Ocean Institute.
The City of Dana Point also suggested that there is a need to establish some type of baseline condition for harbor water quality before the Ocean institute installation. This is so they can see the effectiveness of the Ocean Institute BMPs. However, existing data may not be sufficient to establish a baseline and the Ocean Institute is under construction at this time. It was then suggested by the City of Dana Point that the next viable alternative to determine the effectiveness of the Ocean Institute stormwater management system will be to compare Ocean Institute data to data from other nearby parking lot storm sewer collection systems.

The City of Dana Point expressed enthusiasm for the Ocean Institute project and suggested that this project can be a benchmark that can be used to facilitate similar practices at other projects over which the city or the County has jurisdiction. The City would like to have documented the cost-effectiveness of the Ocean Institute BMPs.

Ocean Institute stated that the majority of the Ocean Institute parking lot would be complete August 1. The new facility will be moved into no later than the 15th of August.

Ocean Institute is keeping weekly project photos. The County's Clean Beach Initiative Grant is funding the BMPs for the Parking Lot.

Action: County of Orange to develop monitoring plan for the Ocean Institute Stormwater Collection system.

Baby Beach State of the Beach Project
This is another project that is being funded by the County's Clean Beach Initiative Grant.

Data Mining
SAIC's progress presented by Andrew Lissner. SAIC received data from the Orange County Public Health Department. They have developed a normalized database from this data and are ready to begin statistical and heuristic analyses of this data. They are still compiling related data sets such as meteorological, tidal patterns, storm sewer condition, bird migration patters, etc. to correlate against the bacteriological data they have received. Once they complete their data mining and collection efforts, they will be poised to complete the data analyses. They anticipate completing these data mining and analyses after August 2002.

GIS Map:
A component of the data analysis effort is collecting DGPS data to document "average" field coordinates at Baby Beach and adjacent sites used by the County to collect bacteriological samples, as well as 10-15 other features, such as ends of storm drains, etc. These data will be added to nominal map and aerial photograph GIS layers to be provided by the County, and used to display a map view(s) in the State of the Beach Report. Depending on needs to display data for the report (based on collective graphics showing data), a map(s) may also be included to display data. This will be completed in parallel (in fact as an integral part of) the data mining task and is anticipated to be completed after August 2002.

CEQA CE:
SAIC is preparing a draft memorandum for a Categorical Exemption (CE) under CEQA. CEQA allows a CE for research and scientific investigation projects of a temporary nature. SAIC will submit the draft memorandum to the County of Orange in approximately mid-May, 2002. The county will then begin its approval process for completion of the CE.

Source Tracking Element of State of the Beach Report

Orange County Health Care Agency (OCHCA) Progress presented by Donna Ferguson:

OCHCA will be conducting bacterial source tracking studies at Baby Beach.

The OCHCA lab does not normally do microbial source tracking analyses. The state of the science for these analyses is in its infancy. There are no standard tests available. There are several procedures that show promise, but none of them will verifiably identify the source of the bacteria. Due to this, OCHC has proposed using three methods, which, when used together, may be able to identify some sources of the bacteria found at Baby Beach.

One of the key issues to overcome is the fact that many bacterial indicators can be found in more than one animal (or human) specie. Multiple sources are not easily separated.

The Orange County Water District (OCWD) has developed/used a method using Bacteroides, which can determine if the source is human or animal. This is one method proposed by OCHC.

Another method proposed by OCHCA is called community analysis: a DNA mapping where you look at total population of bacteria in your sample. You cannot conclusively identify down to bacterial species: but you can say the community in this water sample is different than the community in another water sample. When there is a pollution event, there should be a high diversity in that microbial population. This will help determine different populations of bacteria and thus different sources.

The problem is highly complex and we may or may not identify the source after the investigation is complete.

Dana Point Residents and City Officials stated that the main jetty is covered with guano. Is this potentially a source and will the investigation determine how much this may be contributing?

The County of Orange stated that the circulation study would evaluate to some extent the likelihood of the source being from guano on the main jetty. However the circulation study has not yet been developed or scheduled.

Action: County to incorporate in data mining report a discussion of the circulation studies to date and further circulation data needed to evaluate whether circulation or the lack thereof can impact bacteriological conditions.

Dana Point Residents stated: What about the boat moorings? There are no stations there. Will the investigation evaluate the contribution of these boats? Many boats are live-in boats.

County of Orange had no plan to establish sampling stations in and among the boat moorings.

Action: As part of overall investigation, County to evaluate the possibility of and potential need for sampling in and around boat moorings. County to incorporate the findings in the data mining report.

Dana Point residents asked about petrochemicals dissolved copper and other 303d constituents. They asked why these constituents were not included as a part of the study. One resident raised the possibility that these other non-bacteriological compounds can indicate the potential for bacteriological growth and activity. Others raised the possibility that dissolved oxygen measurements may be indicative of pollution in the harbor.

The County stated that the Clean Beaches Initiative (CBI) grant funding is to focus on bacteria issues. The County stated that the Environmental Resources group of the Watershed & Coastal Resources Division is investigating the 303d constituents.

Action: Sonia Nasser will invite Chris Crompton to discuss Dana Point Harbor 303d list constituents at the next meeting.

The County stated that after August, the SAIC data mining and data gaps analysis report will be complete, the Orange County Health Care Agency bacteriological source study report will be complete, and the CBI grant application for the implementation of BMPs will be complete and available for review.

Next meeting August 1, 2002: 10:30 City of Dana Point City Council chambers, Suite 210, 33282 Golden Lantern, Dana Point, California.
