TEAM BUILDING: Anacostia River Boat Tour

6ff6e92a-9902-42b2-9131-92983141b51a-original

On July 26, the Nspiregreen team went on the Anacostia Watershed Society’s Anacostia Boat Tour as part of this quarter’s team building. This trip gave us a chance to see first-hand and learn more about the efforts being implemented to improve the health of the river. This was a great experience especially since we have been working on some projects related to the Anacostia River’s cleanup efforts.

The Anacostia River watershed is home to 43 species of fish, some 200 species of birds, and more than 800,000 people. The river flows through Montgomery and Prince George’s Counties in Maryland and past the Capitol Building in the District. The watershed is approximately 176 square miles and around 25% of its land lies in the District of Columbia. (Source: DOEE, February 15, 2018, EPA)

The Anacostia has been polluted by litter, raw sewage, stormwater runoff, and industrial waste since the 19th Century. However, in the past two decades efforts have been implemented to turn “The Forgotten River” into a “fishable and swimmable” water body as defined by the Clean Water Act. For example, the recently opened DC Water tunnel between the RFK Stadium and the Blue Plains Wastewater Treatment Plant is preventing millions of gallons of wastewater from entering the river, thus reducing the levels of bacteria. The District’s Department of Energy and Environment (DOEE) launched the “For a Cleaner Anacostia River” initiative aimed to clean the river sediments contaminated with industrial toxins including polychlorinated biphenyl’s (PCBs) and polycyclic aromatic hydrocarbon (PAHs).

Tour Highlights

Below are some highlights of our trip!

Rain, Rain, Rain…

There was a thunderstorm the night before the tour. In fact, this past July was one of the wettest Julys on record! The day we went, the river was yellow-colored and full of broken branches and litter. However, boats were out removing these items. Here is a picture of one of DC Water’s boats cleaning up litter.skimmerboat

Due to the high levels of precipitation, the river’s water level was really high. For this reason, we were not able to go under the Benning Rd bridge. The water was almost hitting the rail bridge! I heard the area north of this bridge has beautiful scenery and lots of wildlife. We will come back again!

The River is Improving

The water condition is getting better; wildlife and the levels of subaquatic vegetation have increased. The tour guide also told us that they are testing the use of mussels to clean the water. Fun fact an adult mussel can naturally filter about 10 gallons of water a day!

The Impacts of Heavy Rainfall on the Environment

The recent rain events this past week caused extreme flash flooding throughout the Northeast region. Parkways, streets, and metro or subway stations in New York, Washington D.C., Maryland, Virginia, and Massachusetts flooded leaving motorists, pedestrians, and commuters stranded and exposed to horrid conditions. I have become worrisome, not particularly of the increase in the intensity and frequency of torrential downpours, but of our current incapacity and mismanagement to handle all of this water. Every time we face intense rain, I have to think to myself: What towns or streets will face flooding? Who would want to walk through a transit system with murky water past their ankles with absolutely no knowledge of what bacteria or toxins lurk in that water? How much more can our water systems take from the toxic materials and untreated wastewater due to outdated infrastructures and sewer systems? Are we really placing public and environmental health, safety, and the quality of life for all as a top priority? Climate change has brought an increase of rain intensity and frequency. Rainfall intensity is the measure of the amount of rain that falls during a period of time while rainfall frequency is the amount of times it rains during a specified period of years. An increase in air and water temperature brings an increase of precipitation.  But we cannot isolate climate change, we must also pay close attention to the factors that it engages with. I can certainly name a few: presence of impervious surfaces, lack of greenspaces, outdated infrastructures and sewer systems. All of these factors exacerbate flooding and can be detrimental to our water systems.

Impervious Surfaces…

The large surface area of impervious surfaces like roads, parking lots, and roofs, that have replaced our natural landscape, do not allow water to infiltrate into the ground and speeds up the process of rainwater runoff entering the drainage systems. The runoff and the pollutants collected from impervious surfaces are either turning into floods or entering our water systems at a faster rate than it can be managed.

Lack of Greenspaces…

This kind of ties in with impervious surfaces. I think it’s safe to say that the more impervious surfaces we create, the less access to greenspace we have. Greenspace is extremely crucial. It provides benefits such as reducing and filtering polluted stormwater runoff, reducing soil erosion, and improving air quality. When we lack greenspace, we have to deal with a lot of preventable challenges. With a lack of soil and vegetation to absorb and filter the rainfall, we experience flooding and overloaded sewers. With a lack of vegetation, we experience an increase in air temperature (Note what I stated earlier about the effects of an increase in air temperature).

Outdated Infrastructures and Sewer Systems…

The outdated infrastructures and the combined sewer systems were built only to hold a certain capacity of rainfall. In addition, transit systems and roadways aren’t effectively updated or repaired. Poor management leads our infrastructures to dilapidate and become swamps. In the recent floods, water leaked through the concrete vaulted ceilings of the WMATA Capitol South metro station. In a few of New York’s subway stations, water entered through the ceiling and stairways flooding the stations. Combined sewer systems are typically found in older cities. When the capacity of the system is surpassed, the untreated wastewater and stormwater runoff flows into our waterways or can back up into buildings through the pipes or overflow from the storm drains onto the streets.

Now What…

With climate change there will be an increase of storm intensity and frequency, but how do we plan and design for worsening conditions? As the climate changes we must adapt our habits, the way we design, and our management of infrastructure. Stormwater management practices are used to reduce stormwater runoff, control flooding, reduce erosion, and improve water quality. These practices include green stormwater infrastructure (GSI), flood control reservoirs, and tunnels (SMART Tunnel in Kuala Lumpur, Malaysia and the Deep Tunnel in Milwaukee, Wisconsin addresses flash flooding and stores millions of gallons of overflow and sewage). Green infrastructure can be used to not only address our stormwater issues but to beautify our communities by creating healthy environments. Just imagine walking, driving, or riding your bike down a green street filled with a canopy of trees, native vegetation, GSI interventions, enhanced sidewalks, public art, and other street design features. A green street utilizes green infrastructure, improves public health and safety, and can even yield economic benefits.

We also have to contemplate all of the paved vacant lots or unused parking lots. For an example, malls all over the United States have an immense amount of parking.  What can we do with these spaces? These are opportunities to implement green infrastructure and green spaces for public spaces that can incorporate activities, pop-up spaces, farmers markets, etc.

In addition to the stormwater management practices, the timely repair and maintenance of infrastructure needs to be a requirement or else it will not function properly. Also, funding should be appropriately allocated to ensure that the proper solutions are identified and instated.

The strategies will not be the same in every location because the approach should be acclimated to the specific needs of that region based on in-depth analysis, research, and community engagement. However, with careful and purposeful consideration and action we can move in the right direction. I leave you with this: How can you be a part of the movement to create safe, equitable, and sustainable infrastructures and communities?

Accessibility for the Disabled in Your Community

Last month when I crossed the street in Fairfax, I saw a very intriguing curb ramp that caught my attention. I noticed that the material on the slope surface is different than elsewhere. At first I was curious why it was designed that way, then I realized the material for the ramp was rougher compared to the rest of the sidewalk, and it has more friction on the surface. I assumed this is for people who are waiting to across the street and not to slip over the curb, especially on a rainy day. Also, for people who may have a physical disability, this kind of material can help the wheelchair gain more friction as they stop to check the traffic. I was surprised when I saw the detailing on the curb ramp to help people, and I started to pay attention – discovering those little nifty helpful details in my community.Picture1

 

As an Urban Planner, we need to do our best to plan for those who have a disability, making sure they can also have access to and can enjoy a high quality of life. When we deal with open space design, such as recreation areas and pedestrian routes, we need to pay more attention in these details. For example, we use Metro as our daily commute and we notice that the metro station does a really good job in providing accessibility: from going down to the train level to getting onto the train.

I found a handbook online: Accessibility for the Disabled – A Design Manual for a Barrier Free Environment.

This book mainly talked about 5 target disability categories:

(a). Wheelchair users

(b). People with limited walking abilities

(c). The sightless

(d). The partially sighted

(e). The hearing impaired

In the urban design consideration, it divided into 10 chapters:

  1. Ramps
  2. Elevators
  3. Platform lifts
  4. Stairs
  5. Railings and handrails
  6. Entrances
  7. Vestibules
  8. Doors
  9. Corridors
  10. Restrooms

The book has many details of the accessibility that we probably haven’t noticed before such as a barrier-free path for the safety and independence of disabled people; symbols of a wheelchair figure with either a square background or a square border. It gives principals about obstructions, signage, street furniture, pathways, curb ramps, etc.Picture2

 

In another article: Technological Innovations in Transportation for people with Disabilities

It talked about using technological advancement to help people with disability, and other technologies that could provide board safety and mobility benefits for pedestrians. Also, target assistive technologies to improve accessible transportation for people with vision impairment and other disabilities. There are 6 topics:

  1. Triggering a Virtuous Circle of Self-sustaining Accessibility and Transportation.
  2. Environmental Awareness for People with Visual Impairments-Gaps, Challenges and opportunities.
  3. Getting there is you are blind: Synergistic convergence of technologies to improve wayfinding.
  4. Using robotic and artificial intelligence to improve mobility and navigation of people with special needs.
  5. Opportunities and innovations in ITS and mobile technology for accessible transportation.
  6. Making technology universally accessible for all users, including those with sensory and cognitive impairments.

Accessibility in urban areas is now of more interest to me. I will continue reading the handbook but also figure out how it applies in reality.

Putting all of this into practice, Nspiregreen is currently working with the  District Department of Transportation on a project called Inclusive Transit – accessDC. The study will identify ways to give people with disabilities and aging adults in DC better access to multiple transportation services, allowing for greater mobility with dignity and independence, and easier integration in the community. I am happy to be a part of a project to make transportation options better for disabled people.
