GEICO campus, Brookdale Park trees facing the clearcut chainsaw in Friendship Heights


What would Warren Buffett do? Well, we know what the Montgomery County Council and Planning Board will do. The recent mega-downsizing of GEICO from its lush, longtime campus in the Friendship Heights area of Chevy Chase to a modest office in Bethesda is quickly leading to a massive redevelopment of that land long feared by neighbors. Central to the plans to building luxury apartments and townhomes on the site is the removal of almost all of the large trees from the 29-acre campus.

"This includes trees that are over 50 inches in diameter; some have been there for more than 100 years," the Little Falls Watershed Alliance warned in a email. "LFWA opposes this large scale destruction of the trees as well as many other elements of the plan that will have a negative impact on the environment." Developer EYA is also seeking permission to remove trees from Brookdale Park, the organization said. LFWA is encouraging residents to email the Planning Department and County Council, and ask them to preserve the trees.

Alarming E.coli count found in Willett Branch stream in Bethesda


Advocates for the Little Falls watershed have been taking water samples from the Willett Branch and Little Falls Branch of the stream in Bethesda for several months, finding that a number of locations had E.coli bacteria counts that exceed the standards for safe water play for humans and animals. The Little Falls Watershed Alliance then sought a more refined testing procedure, to find out what the problem was. Results of those new tests show the contamination is even worse than originally believed.


The newest tests, conducted by the Potomac Riverkeepers Network (PRKN) Rapid Response team, show alarmingly high counts of E.coli at each location where samples were taken. Maryland standards for safe water play allow E. coli levels of 0 to 410 MPN/100ml. A Willett Branch sample taken 300 feet upstream from the Bethesda Pool shows an E.coli level of 12,667.5 MPN/100ml. 


Because a sample taken from a small inlet entering the Bethesda Pool-area stream channel shows "only" 977.5 MPN, and the E.coli counts drop to "only" 8,664.0 and 4,352.0 (south of the pool and by Morgan Drive, respectively), watershed advocates believe there is either a rupture of a sewer line near the Purple Line construction site, or an illegal sewer hookup discharging from a building in that area. The stream was once above-ground there, but was placed underground as Bethesda urbanized.

LFWA and PRKN have reported the situation to Montgomery County and WSSC officials. It will now be up to them to investigate and determine the source of the E.coli. In the meantime, think twice before allowing children or pets to enter the stream.

Half of Little Falls watershed samples fail most recent E. coli test


E. coli tests of samples from two stream branches of the Little Falls watershed in Bethesda show half of the samples did not meet Maryland or District of Columbia standards for water quality. Samples of stream water collected near the Bethesda public pool (Willett Branch) and south of the Massachusetts Avenue bridge (Little Falls Branch) exceeded the "safe" level of E. coli contamination. 


Samples taken upstream from the Somerset Pool (Little Falls Branch) and on the Potomac River side of MacArthur Boulevard near Brookmont (Little Falls Branch) passed, however. The samples were collected, and results reported, by the Little Falls Watershed Alliance

Monitoring E. coli contamination can help alert authorities to sewage leaks in the watershed. But fecal contamination also comes from uncollected pet waste and wildlife that ends up in the streams.

Rain caused flooding on River Road in Bethesda last night (Photos)

A reader sent in photos of flooding on River Road during the torrential downpour early last night, the most significant rainfall event in Bethesda in several months. This was near Willard Avenue, where a branch of the Little Falls Stream passes under River Road. At least one vehicle was stuck in high water, which was higher than it was in these photos at one point.

Supporters of daylighting Willett Branch stream envision "Green Ribbon" within Westbard plan area (Photos)

The Little Falls Watershed Alliance hosted a presentation by Montgomery County Parks and Planning officials last night, on the potential daylighting of Willett Branch stream in the redevelopment of the Westbard Sector Plan area in Bethesda. Planner-coordinator Katherine Nelson of the Montgomery County Planning Department, Suzanne Paul of the Montgomery County Parks Department, and Natural Resources Manager Jai Cole of Montgomery County Parks discussed what the ideal linear park concept would be, and took questions from the audience.

LFWA is leading the advocacy effort to ensure that a daylighted Willett Branch remains part of the final Westbard Sector Plan, expected to be passed next year by the Montgomery County Council. The park would be a "Green Ribbon" in the currently-industrial area off River Road. Combined with a potential urban recreation park beside the Capital Crescent Trail there, it would provide a stream-centered green space that would also allow connectivity among the existing trails in the Little Falls Stream Valley Park.

Officials acknowledged there are no guarantees that the staff vision will end up in the final plan. Nelson said only the Planning Board can make changes to the plan at this stage of the sector plan process, not staff. The board will discuss this and other environmental proposals in the Draft Plan at its December 3 worksession. LFWA President Dan Dozier and Executive Director Sarah Morse made clear that supporters of the vision will have to strongly make their opinions known to the Council, Planning Board, and County Executive Ike Leggett to make it a reality.

Nelson said the ribbon-like park would be walkable, accessible, and provide connectivity between new and existing park amenities. "This double loop just makes so much sense to us," she said, allowing a new connection between the CCT and Little Falls Stream Valley Park, for example.

used - Sugar Creek in North Carolina
While the Parks Department initially began its visioning process with larger-scale models from Los Angeles and North Carolina, they have scaled the concept down by turning to an example closer to home - Sligo Creek.

Cole said Sligo is very similar to Willett Branch, as a channelized stream. Ordinarily, she explained, streams move within their stream valley as a way of naturally discharging energy. But with streams like Willett or Sligo, which run alongside roads, homes and trails, planners can't allow them to move. Hence, they end up as concrete channels.

"Sligo is really one of our success stories," Cole said. When Parks started the transformation of Sligo Creek, she recalled, they found only 2 individual fish in the water. Today, there are now thousands of fish, and 11 species in all.

Cole said planners do not want to rule out such a renaissance in Little Falls Stream. For that reason, they will use 6-inch drops in grade that are within the jumping ability of small fish.

A number of critics of the daylighting proposal have suggested that a revamped Willett Branch would only hold a trickle of water most of the time, and be an expensive eyesore as a result.

"It could be" more than just a trickle once naturalized, Cole said. "I don't know what it is going to look like yet," because the modeling and design phases of such a project haven't even begun, she said. Those will require funding, she said.

Once Parks can conduct testing to determine water flows, measure the water table, and study other existing factors, they will have a better sense of what the finished stream's characteristics will be.

One attendee asked about the "unintended consequences" of the proposal, such as "angry homeowners who will have water in their basements after this."

Cole said that wasn't likely to happen. A change that would bring the flood plain even an inch onto their property, much less into their basement, would require the written approval of homeowners to be built. She said the proposed plan will be designed to keep the stream within its banks in a 100-year flood event. Cole added that water flows will likely be reduced and slightly slower downstream from the Westbard development, as all new construction will require stormwater to be treated on-site, before it enters the stream.

There isn't any money for the project right now, Cole acknowledged. She said it's important to get the project into the sector plan at this point. Then, Parks can try to get the project into its Capital Improvements Program budget in a future year, she said.

Paul concurred, stressing that the recommendations in a sector plan "hold weight" later on. That's one of the points I made in my testimony before the Planning Board in September, as well. If they don't make a recommendation - for example - to deal with traffic congestion on River Road in the plan, such as an extra lane, chances are slim for getting such a project into a future CIP.

The negative aspects of the Little Falls Place townhome development indirectly came up when the topic of elements planners don't want to see in the future Willett Branch stream valley were discussed.

"Buildings in the stream valley." "Barriers to the stream valley." Both happen to apply to the townhome development, which was recently built on the banks of the stream, and has a fence along it. This was permitted because the project was grandfathered in from the 1982 plan.

Other ideas that should be rejected? Direct drains into the stream that pour untreated stormwater into it, roadway pavement in the stream valley, retaining walls alongside the stream, buried segments, and barriers that encourage illegal dumping of refuse.

Nelson noted another urgent issue with the current stream. It has no "owner," and many of its retaining walls "are coming to the end of their life," she warned. Planners who walked the stream have found many cracks, buckling, and structural issues, she said.

Another concern is that the biggest landowner, Equity One, is now asking the Planning Board to back off some of the recommendations the Draft Plan makes regarding the daylighting proposal.

In a September letter to the Planning Board, Equity One asked them to eliminate the recommendation of daylighting the stream along the Westwood Center II property, and to reduce the width of the stream buffer area recommended behind the Westwood Tower apartment building. There are now rumors that the Housing Opportunities Commission of Montgomery County, which currently leases Westwood Tower from Equity One, would like to build a building or garage behind it.

Equity One is also asking that the land on which such stream-related improvements will be make be classified as "easements", rather than recommending outright dedication or acquisition by the County.

One attendee said some on the Planning Board are "caving" to the request, based on their comments at an October worksession.

"Is there anything that forces people to respect that [stream] buffer?" a resident asked.

Cole said the Planning Board makes that decision. It was noted that a similar thing happened in the EYA Little Falls Place project. EYA, which is partnered with Equity One in their Westbard redevelopment proposal, told the LFWA they would allow a 50 foot setback for the buildings at Little Falls Place. It ultimately ended up being 35 feet, which is not what LFWA endorsed in backing the townhome plan.

Paul said planners are going to focus most on the segment of Willett Branch between the Roof Center property and the CCT. That is the area where Parks hopes to acquire land for an urban recreational park. The ideal scenario, Paul said, is that landowners would "be willing sellers."

Of course, that largely depends upon what their land ends up being zoned for in the plan recommendations. One of the points I made strongly during the Little Falls Place/Hoyt Property debacle was that industrial/commercial properties along the Willett Branch should be kept as industrial. That would hold down their sale value, allowing the County to more easily acquire the land.

With the Hoyt property priced as industrial, the County could have acquired it and additional land along the stream to create a large park and stream buffer. Ideally, additional industrial land could have been acquired along Butler Road up to the gas stations on River Road (over time) to enlarge this further. It would have been far larger than any of the currently-proposed postage stamp pocket parks in the Draft Plan, and would have provided a refuge for wildlife in the area. The Hoyt outcome severely hobbles the potential of such a plan, but emphasizes why the zoning proposed in the plan will directly affect the potential to acquire parkland and buffer areas.

Morse exhorted attendees to write letters to the Council, Planning Board and Leggett.

Springfield Civic Association President Phyllis Edelman said supporting the Willett Branch proposal is important, because "we're not going to have a lot of positive [amenities in the current Draft Plan] for us. So we need this not just for our community, but for the community that will be built."

If you want to email the specified officials, to tell them to support the daylighting plan for Willett Branch, here is where you can reach them:

Planning Board Chairman Casey Anderson

Montgomery County Council

County Executive Ike Leggett

Dozier said that if everyone in the room sent just one email to each official, it would make a huge difference in the effort, which will determine "what our kids' neighborhoods will look like in the future."

I'd like to also have at least one major facility - i.e. a recreation center - and a significant park (not just a tiny, loud, skate park or green postage stamp) be added to the final Westbard Sector Plan. There are no County facilities in the Westbard area besides the Little Falls Library, and the area has been neglected for decades in that department.

COAST GUARD, EPA, HAZMAT TEAM INVESTIGATE RED SUBSTANCE FLOWING THROUGH PIPE BENEATH DOWNTOWN BETHESDA

COUNTY, STATE, FEDERAL AUTHORITIES
RESPOND AFTER STORMWATER UNDER
BETHESDA - AND LITTLE FALLS STREAM -
TURN RED THURSDAY

ANOTHER ROBERT DYER @ BETHESDA ROW EXCLUSIVE!!!

Several Bethesda residents were startled Thursday when a tributary of Little Falls Stream turned red.

Some reported their discovery to the Montgomery County Department of Environmental Protection.

The tributary is near the Bethesda Pool between Bradley Boulevard and Little Falls Parkway.

According to Steve Martin of the DEP, agency employees were on the scene before 4:00 PM Thursday.  Based on their experience, they believed it was a harmless dye used often to test pipe flows.  However, they conducted several tests to be certain.  Tests for typical stream pollutants were all negative.  They found no ill or deceased wildlife in the water.

One or more citizens who had noticed the red substance called the National Response Center of the EPA.  As a result, members of the Coast Guard, EPA, and a Montgomery County Hazmat team rushed to the scene, as well.  All agencies eventually reached the conclusion that it was a dye.

Friday, they checked the outflow north of the pool, and it "was clear," Martin said.  It turns out the pipe that empties into the tributary runs underneath Arlington Road, as far north as Hampden Lane.  Agents checked the water at Hampden Lane and found it was clear there, too.

After some further investigation, the DEP has concluded that the red substance came from a commercial or residential building in downtown Bethesda, between Hampden Lane and Bradley Boulevard.  Martin said it will be difficult to determine exactly which building was responsible.

Authorities seem satisfied that there is no danger to the public or wildlife.  However, the conclusions did not seem to include a definitive identification of the red mystery substance.  Did you notice the red water anywhere in the Little Falls watershed?  Are you satisfied with the DEP explanation?  Leave your comments below.

There doesn't appear to be any evidence that the substance is toxic so far.  However, there are many known and unknown pollutants in the Little Falls stream.  Personally, I would advise people to not make contact with the water in this, or almost any other stream in Montgomery County.  And that includes pets, as well.  There are a variety of natural and chemical pollutants, and in some cases, sewage contamination.  Little Falls has been under a water advisory for excessive levels of bacteria on occasion.

I can recall seeing soap-like suds and bubbles in the Little Falls watershed on two separate occasions.  What's that about?  And sometimes there will be an odd smell, such as around the branch that crosses underneath River Road, just west of Willard Avenue.

So, enjoy the streams, but use common sense and practical precautions.
