4. MS4 Program Resources

The County Board approved a sanitary district tax in April 2008 to fund an expanded stormwater

management program. The approved sanitary district tax rate is currently $0.013 per 100 dollars of

assessed property value. This tax generated approximately $8.6 million in funding for FY 2015, with

all tax revenues placed in a dedicated Stormwater Fund. These funds provide funding for stream

restoration and watershed retrofit planning, design, and construction, site inspections, stormwater

facility inspections and maintenance, engineering plan review, and regulatory compliance. The

Stormwater Fund also provides funding for system capacity improvements in critical locations and

proactive system maintenance and replacement.

Adopted FY16 budget for stormwater:

**List sent to DEQ on August 28, 2014

Summary of actions taken to implement statutory and regulatory requirements of the Virginia

Stormwater Management Program Regulations.

All projects with land disturbing activity exceeding 2,500 square feet are reviewed for compliance with the County’s Stormwater Management Ordinance (Chapter 60 of the County Code) and Chesapeake Bay Preservation Ordinance (Chapter 61 of the County Code) in DES/DTD/DSB, with regulatory, policy and technical support provided by DES/OSEM. In addition, most activity within the Resource Protection Area (generally within 100 feet of a stream channel) is reviewed by DES/DOT/DSB and DES/OSEM, regardless of the level of land disturbance. - For development prior to 7/1/2014, Chapter 61 and the Stormwater Detention Ordinance

(Chapter 60 of the County Code) required the control of post-construction stormwater quality and quantity from development projects.

- Development after 6/30/2014 is regulated by the new Chapter 60, adopted on 05/10/2014 to reflect the modification required by Virginia Stormwater Management Act (62.1-44.15:24, et seq.) and Virginia Stormwater Management Program (VSMP) Permit Regulations (9 VAC 25-870-10 et seq.).

- Chapter 61 of Arlington County Code was revised and adopted on 05/10/2014 for consistency with the new Stormwater Management Ordinance.

i) Storm Sewer Infrastructure Management

Infrastructure Inspection and Maintenance

1Efforts concentrated on catch basin inspections and maintenance in FY14.

Progress summary on efforts to repair failed storm sewer outfalls.

A preliminary document search has been completed for the outfalls identified in the County-wide

stream assessment that scored a 4 or 5 on the outfall condition severity scale. A review of these

documents indicates that 20 of the outfalls are on private property (easement documents have

been identified for 14 of these); 12 are on public land or in the public right of way; 3 are on

property owned by the US government; and the ownership of one outfall is unclear.

Therefore, of the 36 outfalls1, 26 are on public land or within an easement. There is also one

additional outfall not included in the original County assessment but identified as part of the

Donaldson Run Tributary B stream restoration project—which makes the total 37 outfalls. This is

1 Note: The permit references 35 outfalls as scoring 4 or 5 on a severity scale during the County-wide stream assessment. In fact, there are 36

outfalls.

the outfall referenced in the permit as “associated with the…Donaldson Run stream restoration

project….”

For the three outfalls associated with the Donaldson Run and Windy Run stream restoration

projects, design has been completed and temporary and permanent easements obtained for two

of these outfalls. The easement negotiation for the third outfall (Windy Run) is underway.

The next step for the other 34 outfalls is to develop concept plans for the repair/rehabilitation of

the individual outfalls, which will include an evaluation of the feasibility of access (including

building obstructions, steep slopes, forest area, etc.) and the need for temporary construction

easements (in most cases existing easements are inadequate for access and construction

purposes).

As individual outfalls are evaluated, repair/rehabilitations will be prioritized within the larger

stormwater infrastructure work program outlined in the adopted Stormwater Master Plan and the

Capital Improvement Plan (CIP), which includes major storm sewer capacity and flood risk

reduction projects, as well as other non-capacity related drainage projects (e.g. drainage

complaints, sump pumps discharging into the right of way, capital maintenance, etc.).

k) Public Education/Participation

Arlington County conducts education and outreach activities for a comprehensive variety of

stormwater and watershed management issues, including nonpoint source pollution, illicit

discharges and pollution prevention, household hazardous waste, litter, and recycling, stream

buffer and stream restoration, and water quality monitoring. Some activities are conducted annually

26

and others vary each year. These programs range from volunteer stream cleanup events, storm

drain marking, and school and civic group presentations to Web-based information and multi-media

outreach efforts (including posters in Metro stations and the Northern Virginia regional education

campaign).

Stormwater- and watershed-related public education activities are conducted primarily by DES and

PRCR staff, with a variety of collaborative efforts undertaken with other Northern Virginia

jurisdictions, Arlingtonians for a Clean Environment, Northern Virginia Regional Commission,

Northern Virginia Soil and Water Conservation District, and other organizations.

The table below provides the reporting information required by the permit: a list of permittee

public outreach and education activities and the estimated number of individuals reached through

ii. Continue to promote individual and group involvement in local water quality improvement

initiatives including the promotion of local restoration and clean-up projects, programs,

groups, meetings and other opportunities for public involvement;

The County also manages several stream volunteer programs, including stream monitoring

and storm drain marking.

Over 100 volunteers participated in the County’s stream bacteria and macroinvertebrate

monitoring programs (http://environment.arlingtonva.us/streams/stream-monitoring/) in

FY2015, providing over 900 volunteer hours. Through Arlington’s storm drain marking

program (http://water.arlingtonva.us/sewer/storm-drains/), volunteers donated 168 hours,

and marked over 1,300 storm drains with the “Only Rain” storm drain marker. During the

2014 calendar year, over 90 miles of Arlington’s streets were walked and marked by

volunteers in the storm drain marking program. As of August 12, 2015, in calendar year

2015, 29 miles of Arlington’s streets had been walked and marked. The number of miles for

calendar year 2015 will increase as volunteers continue their work through the end of

October.

iii. Promote, publicize, and facilitate the proper management and disposal of used oil and

household hazardous wastes;

Household Hazardous Material Program - The County’s Household Hazardous Materials

(HHM) program promotes, publicizes and facilitates proper disposal of household hazardous

waste. The County’s HHM facility is open year round for residents to drop off materials, and

the County also organizes two large drop off events (ECARE) each year. The program is

publicized through its webpage (http://recycling.arlingtonva.us/events/e-care-spring-2015/),

Facebook, Twitter, and articles within The Citizen, Arlington County’s citizen newsletter. In

addition, proper disposal of used motor oil is one of the key messages addressed in the Only

Rain Down the Drain education campaign.

iv. Promote, publicize and facilitate the proper disposal of pet waste and household yard waste;

In 2015, Arlington County continued to support the Northern Virginia Clean Water Partners

Only Rain Down the Drain campaign, a regional stormwater education campaign. The

campaign has used radio advertising, online advertising and most recently cable TV

advertising to educate the public about preventing water pollution. The campaign includes

several television ads to help visualize water pollution, and includes pollution prevention

messages related to pet waste, motor oil, car washing, and fertilizer.

Fertilize fewer times per year 9%

More careful with motor oil 4%

*Viewership numbers for TV ads; can include viewers who viewed the ad more than once.

During the summer of 2015, a survey was conducted of 500 northern Virginia residents to measure the effectiveness of the campaign. Fifteen percent of the respondents recalled seeing the advertisements on TV. Men were significantly more likely than women, and homeowners were more likely than renters, to report seeing the ads, which demonstrates that the targeting of the ads to the male/homeowner audience is successful. Of those respondents who recalled the ads, eleven percent state they now pick up their pet waste more often, nine percent state they plan to fertilize fewer times per year, and four percent are more careful with motor oil.

In addition to the Only Rain Down the Drain Campaign, Arlington County has created new dog waste signs to post near the dog parks, reminding users to pick up after their dog. Pet waste surveys will be conducted prior to the signs being posted, and following the installation of the signs, to see if there is any reduction in the amount of visible pet waste from the educational signs.

v. Promote, publicize and facilitate the use of the county’s recycling program;

The County has a very successful recycling program. The County promotes the use of the

recycling program and guidelines on what to recycle in several ways:

- Spring Yard Waste Brochure (distributed to 34,000 households) - Fall Yard Waste Brochure (distributed to 34,000 households) - Insert in the November/December issue of the Arlington Citizen (distributed to 100,000

households) - Annual Multi-Family and Business/Commercial Recycling Compliance Outreach Visits - Master Recycling Composter Ambassador Training – This is a new training program

started in 2014 to educate volunteers to assist with providing recycling and composting education to the public.

vi. Promote, publicize and facilitate methods for residential car washing that minimize water

quality impacts;

See Section iv. - Only Rain Down the Drain campaign.

vii. Promote, publicize, and facilitate the proper use, application, and disposal of pesticides,

herbicides, and fertilizers by public, commercial, and private applicators and distributors;

See Section iv. - Only Rain Down the Drain campaign.

http://www.onlyrain.org/

31

County staff worked with a local writer to develop an article on the benefits of reducing lawn.

The article, entitled “Lawn Gone”, appeared in the May 2014 issue of the Arlington magazine.

viii. Encourage private property owners to implement retrofits including those described in Part

I.B.2.c);

StormwaterWise Landscapes

The StormwaterWise Landscapes program provides incentives for private property owners to

remove pavement, or install rain gardens, permeable pavement, or conservation landscaping.

Program participants receive a property assessment and written report with

recommendations for practices that are appropriate for their property, and participants can

select one or more practices to install. See Section B.2.c for summary information.

Rain Garden Workshops Arlington County partners with the Northern Virginia Soil and Water Conservation District and

the Northern Virginia Regional Commission to conduct Rain Garden for Homeowners

workshops twice each year.

The rain garden workshops are generally well attended, attracting 30-40 residents for each

session. A follow up survey of workshop attendees showed that 24% of the attendees

installed a rain garden after attending the workshop, and 53% stated that they are still

planning to install a rain garden. Also, 75% of respondents had taken another action at

home besides installing a rain garden. Most popular actions to take were re-directing

downspouts, installing a rain barrel, replacing lawn area with other vegetation, or using native

plants.

Regional Rain Barrel Program Arlington County continued to support the Northern Virginia Regional rain barrel program

over the past year, including helping staff two rain barrel workshops. Nearly 3,000 rain

barrels have been sold, with more than 900 of those rain barrels going to Arlington residents,

with a 90% satisfaction rate for workshop participants. This equates to 125,000 gallons of

stormwater that can be collected and retained during every storm event.

ix. Target strategies towards local groups of commercial, industrial, and institutional entities likely

to have significant stormwater impacts.

http://www.arlingtonva.us/departments/EnvironmentalServices/Sustainability/page83039.aspx

32

Arlington County has created several educational materials targeted for various commercial

and industrial audiences. These include:

- Folder with pollution prevention fact sheets for property owners and businesses - Poster on proper Fats, Oil and Grease storage and disposal for restaurants - Brochure on proper Fats, Oil and Grease storage and disposal for restaurants - Fact Sheets on Dry Cleanup Methods for Restaurants - Brochure of proper de-chlorination and disposal of pool water - Postcards for food truck operators on preventing pollution - Graphic Field Guide and Post card on erosion and sediment for construction contractors - Graphic Field Guide on Pollution Prevention for construction contractors - Postcards on Sawcut Slurry, Erosion and Sediment Control and Construction Debris for

The Arlington County Police Department operates on a two year cycle for Hazardous Materials /

Spill Response training. The last training of all sworn officers took place in 2014 and the next

one will be done in 2016. Even though 2015 is an off-year, ACPD had 27 recruit officers

complete 5 hours of training.

All Arlington County Fire Department emergency response personnel are trained and certified

during recruit school at the Fire Training Academy to the VA State Hazardous Materials Operations

Level. This curriculum covers spill response and includes diking, damming, and diverting

techniques. In FY15, seven recruits received training and certification.

Personnel with the Arlington County Fire Department Hazardous Materials Team are certified to

the Technician and Specialist Levels. Members of the Hazardous Materials Team are required to

take monthly training to maintain their certification levels. Records of training are kept in the

Fire Records Management System (FRMS). Approximately, 45 ACFD personnel received

Technician level training; 26 of those personnel received Specialist level training in FY15.

35

In FY15, Hazmat Refresher training (Global Harmonized System, Emergency Response review,

Detection and Monitoring review) was provided to ACFD staff (~221) at each of the ten Fire

Stations.

See Appendix I for Summary of Training and Certification for Plan Reviewers, Inspectors, and

Program Administrators.

m) Water Quality Screening Programs

1) Dry Weather Screening Program

Storm sewer inspections see Part I.B.2.j)

Bacteria sampling. See C.1.a for details.

Additional bacteria sampling. See C.1.b for details.

Annual outfall screening in Shirlington commercial district and the South Four Mile Run Drive

industrial area.

Procedures, methodologies, and outfall locations for dry weather screening of outfalls that drain the

Shirlington Commercial District and South Four Mile Run Drive industrial area can be found in the

Arlington County Dry Weather Screening Plan in Appendix G of the Program Plan.

Seventeen outfalls were screened in FY15. Of the 17 outfalls screened, 10 had flowing water and

were tested. Six outfalls tested had elevated levels of fluoride and surfactants. These results may be

the result of washing activities, potable water discharges (irrigation, AC condensation) or naturally

occurring fluoride in groundwater. Follow-up upland field investigations did not reveal a specific source

with the exception of one discharge tracked back to washing activities being conducted at a rental car

business. The business has a VPDES general permit for car washing from the VA DEQ.

2) Wet Weather Screening Program

The County developed a list of prioritized areas thought to be contributing significant pollutant loads

during wet weather events. The list is provided in section 1.B.2.h (industrial and high risk runoff).

Wet Weather Screening. Procedures and methodologies for wet weather screening can be found

in the Arlington County Wet Weather Screening Plan in Appendix H of the Program Plan.

Screening will be conducted quarterly at two areas each year.

In FY15, wet weather screening was conducted at two selected sampling locations; a storm drain at

retail shopping strip along Columbia Pike (2705-2601) and an outfall the drains various auto repair

businesses near 4068 S. Four Mile Run Drive. Screening was conducted on a quarterly basis at both

sites, for a total of eight screenings. Screening parameters included: E. Coli (col/100mL), TPH (mg/L),

Nitrate and nitrite (mg/L), Ammonia (mg/L), Total Suspended Solids (mg/L), Chemical Oxygen

Demand (mg/L), Total Phosphorus (mg/L), Total Kjeldahl Nitrogen (mg/L), Zinc (g/L), Cadmium

(g/L), Copper (g/L), Lead (g/L), Chromium (g/L), Nickel (g/L), and Hardness (mg/L). Floatables

were also captured and inventoried.

Results of wet weather screening at the two selected locations is provided in the following table.

The County notified the auto repair businesses about non-stormwater discharges (wash water) to the

storm drain system and surface waters. Notices of violation were sent to the businesses. The County

notified VA DEQ about the wash water discharges observed at the S. Four Mile Run Drive outfall.

One of the businesses has ceased washing outdoors. The other establishment recently received a

VPDES General Permit for Car Washing from VA DEQ.

County staff worked with several of the businesses located within the Columbia Pike retail shopping

strip on improving housekeeping, eliminating wash water discharges, improving waste management,

and managing used grease storage containers. Educational materials were provided to several

establishments.

C. MONITORING REQUIREMENTS

1. Bacteriological Monitoring

a) Four-Mile Run Watershed

Monthly sampling locations

The 11 sample locations required by the permit are described in the Program Plan.

Also, as described in the Program Plan, in addition to the original 11 monitoring locations, Arlington

added the following four monitoring sites between 2005 and 2012: DR1, DR2, LBR 3 and FMR 9. DR1

and DR2 are located outside of the Four Mile Run Watershed.

Detailed information and data on the County’s bacteria monitoring program can be found at:

http://environment.arlingtonva.us/streams/bacteria-monitoring/

http://environment.arlingtonva.us/streams/bacteria-monitoring/

40

In advance of the ‘additional watersheds’ requirement of C.1.b, 6 new sites were added in FY14. At

the time of permit issuance, Little Pimmit Run was the only watershed to have an identified, additional

bacteriological impairment within Arlington’s jurisdictional limits. A new bacterial monitoring site was

added in the Little Pimmit Run Watershed (LP1). LP1 coincides with the existing macroinvertebrate

monitoring location on Little Pimmit Run. Because Arlington does not have two additional impaired

watersheds, two additional monitoring locations located within non-impaired watersheds were added:

Gulf Branch and Windy Run Watersheds. In addition to these, three new bacteria monitoring sites were

added within the Four Mile Run watershed (LBR1, LBR2 and DB1).

A description of the 6 new sites is provided in the Program Plan. A summary of the FY14 data for the

6 newly sites is included in the section below.

The total number of bacteria monitoring sites is 21.

Analysis of E. Coli Data and Precipitation Relationships is available in Appendix F

For the purposes of this report, the 21 monitoring stations are separated into north and south Arlington

locations (with Rt. 50 as the dividing line). A map of the bacteria stations is available online at

http://environment.arlingtonva.us/streams/stream-monitoring/.

General summary

A total of 252 samples were collected over the course of FY 2015 resulting in a 100% coverage of the

program’s sites. Out of the 252 samples, 20% (51 samples) exceeded the primary contact recreation

water quality standard (WQS) of 235 CFU/100 ml (CFU stands for colony-forming units). Of the 51

primary exceedances, 10% (5 samples) also exceeded the secondary contact recreation WQS of 1173

CFU/100 ml. When compared to FY 2014, in FY 2015, there was an 18% decrease in the number of

primary WQS exceedances and a 14% decline in the number of secondary WQS exceedances. In light

of the large quantity of rainfall that was received in June 2015, this downward trend is especially

notable.

As was also the case in FY 2014, most of the WQS exceedances in FY 2015 occurred during the warm-

weather months. In FY 2015, 90% of the WQS exceedances occurred in the summer/fall period (July

through October) and in the spring (April through June). During the winter months of November 2014

– March 2015, the average E. coli concentrations for the 21 monitoring sites were below the primary

WQS of 235 CFU/100ml, and ranged between 36 and 187 CFU/100ml. This finding is expected, as the

colder temperatures would not encourage bacterial growth and dog walking activities likely decrease

along the stream valleys during cold weather. Schueler2 notes that fecal coliform, of which E. coli is a

subset, are typically lower in winter months.

The FY 2015 data do not provide support for a correlational relationship between rainfall within three

days or within 4 weeks of sampling and primary WQS exceedances.

3 The actual calculation of exceedance frequency for regulatory purposes is more complex and is not presented here.

4 All secondary exceedances are included in the primary exceedance total. For every exceedance of the secondary standard (1173 colonies/100ml),

the primary standard (235 colonies/100ml) was also exceeded.

5 Volunteers do not count above 60 colonies on a cultured plate. For purposes of the computations: a 1ml sample with >60 colonies equates to

6000 colonies/100ml; a 2ml sample with >60 colonies equates to 3000 colonies/100ml; a 3ml sample with >60 colonies equates to 2000

colonies/100ml; a 4ml sample with >60 colonies equates to 1500 colonies/100ml; a 5ml sample with >60 colonies equates to 1200 colonies/100ml

Summary of FY 2015 data for added sites.

Figure-1 displays the average of the monthly data for the northern and southern sites. Charts for each

individual site are at the end of this section. In June 2015, six of the nine southern sites exceeded the

primary WQS and one also exceeded the secondary standard, causing the significant increase in the

average for the southern sites. The elevated June bacteria counts are consistent with the fact that

June 2015 was recorded as the second rainiest month on record at Reagan National Airport in Arlington

(http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2015/07/01/stormy-june-goes-

down-as-second-wettest-sixth-warmest-in-washington-d-c/). An unexpected result, however, is that

FY 2015 experienced a decline of primary and secondary exceedances. Of the 21 sites, 12 (57%) did

not exceed the primary standard in June in spite of the rain. Eighteen out of the 21 sites had an annual

E. coli average below the primary WQS, as noted in the summary charts.

6 For the purposes of the computations, if volunteers do not have any colonies on their plate: a 1ml sample with zero colonies equates to <100

colonies/100ml; a 2ml sample with zero colonies equates to <50 colonies/100ml; a 3ml sample with zero colonies equates to <34 colonies/100ml;

a 4ml sample with zero colonies equates to <25 colonies/100ml; a 5ml sample with zero colonies equates to <20 colonies/100ml per direction for

VA DEQ.

7 For the report’s calculations, the < and > signs were not included and the number of colonies following the sign was used. For example, <34

was treated as 34.

Figures 2 and 3 compare the FY 2014 and FY 2015 monthly averages for the northern and southern

sites. Both the northern and southern sites saw improvements in FY 2015 over FY 2014. When

comparing the monthly averages:

The northern average exceeded the primary WQS only once in FY 2015; there were seven

exceedances in FY 2014. (It should be noted that the April 2015 average in FY 2014 exceeded the

primary WQS by two colonies with an average of 237CFU/100ml.)

The southern average exceeded the primary WQS five times in FY 2015; there were eight

exceedances in FY 2014.

The southern average did not exceed the secondary WQS in FY 2015; two exceedances took place in

FY 2014.

Monitoring procedures

The monitoring procedures are detailed in the DEQ-approved Quality Assurance Project Plan

(QAPP), which was updated and approved in August 2014. The QAPP is available online at

http://environment.arlingtonva.us/news-bacteria-monitors/ and the procedure is detailed at

http://environment.arlingtonva.us/news-bacteria-monitors/bacteria-monitoring-protocol/.

The monitoring data are posted to the County’s stream monitoring site

(http://environment.arlingtonva.us/streams/stream-monitoring/) and to DEQ’s Citizen

Volunteer/Non-Agency Monitoring Database, in addition to the data analysis provided in this report.

2. Biological Stream Monitoring

Monitoring locations

The 10 sample locations required by the permit are described in the Program Plan.

Summary of monitoring results and analysis

An expanded version of the summary information below is provided in Appendix G.

Average Number of Orders

In FY 2015, the average number of orders for seven out of nine of Arlington’s monitoring sites

remained the same or increased. The averages for Gulf Branch, Lubber Run, and the reference

site decreased in FY 2015. When compared with earlier data collected using the current

protocol:

Four sites have shown an improvement in the average number of orders between FY 2013 and FY 2015 – Little Pimmit Run, Bluemont, Upper Long Branch, and Barcroft.

Five sites have shown variability in their average number of orders with alternating increases and decreases between FY 2013 and FY 2015 – Windy Run, Donaldson Run, Gulf Branch, Banneker, and the reference site.

Lubber Run had a decreasing average number of orders between FY 2013 and FY 2015.

Dominant Taxa

During FY 2015, the dominant taxon represented anywhere between 24 and 79 percent of the

sample, compared with the FY 2014 range of 31 - 95 percent. The dominant taxon in the

reference samples ranged between 14 and 19 percent in FY 2015 and 18 and 26 percent in FY

2014. Lower percentages reflect a more diverse community, which is expected at the reference

site. It is encouraging to see the percent range for the Arlington sites was lower in FY 2015 than

FY 2014.

However, only four taxa were dominant in Arlington in FY 2015, compared with seven taxa in

FY 2013 and FY 2014 – as shown in the table below. Based on three years of data, Arlington

sites (not including the reference site) are dominated by very few taxa that are pollution tolerant.

Gini-Simpson’s Index of Diversity and the Effective Number of Taxa

The Gini-Simpson’s Index of Diversity (GSID) and the Effective Number of Taxa (ENT) were also

used to evaluate Arlington’s data. Summary results are provided below, with more detailed

information provided in Appendix G.

Figure-4. ENT values for FY14 and FY15

Higher ENT values indicate a healthier macroinvertebrate community. As expected, the reference

site had the highest ENT values in all seasons. None of Arlington’s nine sampling sites consistently

outperformed the others with regard to ENT values (Figure 4). Overall, ENT values to date for

Arlington indicate:

There is not a strong seasonal trend across sites. Half of the sites (5/10) in FY 2014 and FY 2015 had their highest ENTs during the summer season. However, there was variation between the two years as to which sites experienced their highest ENT values in the summer. Only three sites, Windy Run, Banneker and the reference site, experienced their highest ENTs during the summer in both fiscal years.

Half of the monitoring sites had their lowest ENT values in the fall season. Like with the highest ENT values, there was variation between the two years as to which sites experienced their lowest values in the fall.

Values can vary widely at a site. For example the Banneker ENT values ranged from 5.2 to 2.6 in FY 2015.

Northern sites that drain directly to the Potomac (Windy Run, Gulf Branch, Little Pimmit, Donaldson Run) do not consistently have higher ENTs than Four Mile Run drainage sites. By taking the average of the ENT values for FY 2014 and FY 2015, the Potomac sites were ranked as having the 4th, 5th, 8th, and 9th highest ENT values.

49

With the addition of data in future years, we expect more information to determine which of the observations above are meaningful and which are due to natural variances or anomalies that appear in the current small dataset

Summary/conclusions

Based on this most recent assessment, episodic nonpoint source pollution and the impact of

“flashy” storm events are believed to be the primary sources of stress in Arlington streams—as

would be expected in our urban watersheds. There is not any evidence that indicates a single,

point source of pollution as the cause. We also do not believe that habitat is a limiting factor for

the macroinvertebrate community based on the professional surveys conducted in 2011/2012

and 2015. The data indicate seasonal and yearly variability across Arlington’s sites and overall

the stream health across Arlington’s streams is similar. The reference site performed the best

in all of the studied metrics, which was expected.

Overall, a longer study period and accompanying data are needed for all of the metrics included

in this report. However, based on the short term data collected to date, the key findings from

each metric are below.

Average number of orders:

Four sites have shown an improvement in the average number of orders between FY 2013 and FY 2015 – Little Pimmit Run, Bluemont, Upper Long Branch, and Barcroft.

Five sites have shown variability in their average number of orders with alternating increases and decreases between FY 2013 and FY 2015 – Windy Run, Donaldson Run, Gulf Branch, Banneker, and the reference site.

Lubber Run had a decreasing average number of orders between FY 2013 and FY 2015.

Seasonal average number of orders:

There is variability amongst the sites as to when each experienced their highest and lowest average number of orders.

The seasonal averages are very similar.

Dominant taxa:

Arlington sites (not including the reference site) are dominated by a few taxon that are pollution tolerant.

Seasonal dominant taxa:

Ephemeroptera Baetidae dominated samples mostly during the summer and fall seasons (22 of 26 times). Chironomidae dominated samples a majority of the time in the spring (11 of 12 times).

Effective Number of Taxa (ENT):

There is not a strong seasonal trend across sites. Values can vary widely at a site.

50

Northern sites that drain directly to the Potomac (Windy Run, Gulf Branch, Little Pimmit, Donaldson Run) do not consistently have higher ENTs than Four Mile Run drainage sites.

Community Tolerance (CTOL):

Higher ENT values (better diversity) do not necessarily correlate with lower CTOL values (more sensitive organisms).

The three most sensitive communities, after the reference site, were located outside of the Four Mile Run drainage area (Windy Run, Gulf Branch, and Donaldson Run).

The universe of privately-owned stormwater management facilities is growing rapidly, with nearly 500 new

facilities added in FY15 as a result of the new and more stringent Stormwater Management Ordinance. As

a result, the number of owners in NOV status is growing proportionately—although the overall compliance

rate remains high. Following up on NOVs, even if a very small proportion of the total universe, is a

significant and growing workload.

Also, inspection notifications were not sent to owners of 16 stormwater management facilities due to a

database error that has been corrected.

Development Load Changes and Load Reductions from SWMF for FY15

See Appendix J for load reduction from SWMF installed with development activities and retrofit projects

completed in FY15, along with load deductions from SWMF missed in FY09-FY14 accounting.

During FY15 report generation several structures were found that were mislabeled in the database as

water quantity instead of water quality, but the development load had been accounted for in the FY09-

FY14 accounting.

53

3) Estimated Reduction Achieved through FY15

With the POC reductions from FY 2015 in place, the 5% POC reduction requirement

for this permit cycle has been met. The means and methods implemented to date

include watershed retrofit projects, stream restoration projects, redevelopment-based

reductions, and 2006-2009 ‘historical BMPs.’

4) Control Measures Expected to be Implemented during Permit Cycle. See Appendix C

of the Action Plan document.

2. TMDL Action Plans Other than the Chesapeake Bay TMDL
