Storming and Norming lead to Underperforming

Just from my brief exposure so far, I have concluded that the management of stormwater runoff is typical of our engineered environment in that much effort is put into the design and construction of a device, after which ensues a lifetime of neglect. It's not due to lack of regulation or even oversight, but a lack of attention by owners and a failure of governance. A well constructed stormwater pond can degrade due to erosion, poor control of vegetation, or flowpath blockages and remain that way for years, all the while earning its full TMDL credit, though performing only half as well as it should. The local authorities are loath to penalize or even notify violators of their maintenance obligations out of fear of having a negative economic impact on business. State and federal enforcers are just as remiss.

Now that Environmental Site Design has downscaled the control of stormwater to smaller devices spread throughout a new development site, it will be interesting to see whether things will be better maintained due to aesthetics and scale. Education will be key. Fortunately, the Design Manual spells out the maintenance requirements for each device type.

Here's the type of problems that degrade a stormwater pond. The photo here is from a place I frequent that has not been maintained much for about 5 years. Trees grow on embankments where the roots compromise the dam's ability to hold water. Banks are eroded into the pond, reducing the vegetation inside, causing pooling of water, and reducing the overall pond capacity. Cut trees are left inside the pond, putting more nitrogen into the watershed as they decay. I hope to catalogue many stormwater devices such as this in Calvert County over the coming months and use this in presentations to those who need to know. They will be posted on my newest tab on this blogger site.

The Grass is Always Greener when You Can Sell It

When my Watershed Stewards Academy instructor blithely offered that we should stop cutting our lawn grass for the sake of better nutrient and water retention I wasn't sure if she meant stop entirely or just let it grow longer than normal. I suspect the latter, which would also support the outside-the-box idea proposed by Gene Logsdon to grow fodder crops in lieu of turf. In my case, there is only a small area remaining on my property that would lend itself to grass. I went the conservation landscaping route a year ago and my mowing duties have been minimal since.

I've been thinking of planting grass on the strip remaining in front of my Kentucky fence. I've also been trying to come up with a good guerilla gardening idea for the right-of-way that fronts the forested lot under the power lines running on the far side of my street. Aside from the black raspberry plant I stuck there last week, this just might be the best way to go.

Growing long grass will push the limit on the HOA's rules, but if I'm going to use that grass for fodder, so would keeping a barnyard animal. Until I get to that level, I'm sure there will be someone in my circles who would appreciate the extra feed. It would also serve well as a compost activator.

An Offer You Can't Refuse

Earthworks like swales are ways to direct and slow the flow of surface water, but the low hanging fruit for livestock farmers to reduce nutrient flows into the Bay is installation of riparian buffers. That is, they should build fences to exclude grazing livestock from access to streams. If they want to save on a big fence bill and have an even more helpful result, they should consider rotational grazing. In any case, simple fences that allow wildlife to get through are an important feature.

The Best Management Practice (BMP) with the next highest potential to achieve TMDLs is conservation tillage, which includes no till and minimum till. When you include biochar as a soil amendment (not yet recognized as a BMP, but deserves that distinction), humus formation is accelerated by perhaps a factor of 10. Conservation tillage relies on humus and plants to make up for the absence of artificial soil aeration. As the years go by, such soil-building measures make it possible to reduce fertilizer additions to zero.

Biochar would also be useful just for its filtering ability in such devices as micro bioretention ponds and ditches. Specifications for these includes 2 feet of sandy soil, but a smaller amount of biochar could provide the same drainage and many times the nutrient filtering of the current designs. It would also yield better plant root growth than just sandy soil.

+Paul Stamets used buried burlap sacks loaded with mycelium to filter runoff from his property. It worked so well, it amazed the government inspectors who came to see the results.

These are all examples of how more effective measures are possible, but not promoted by the bureaucracy, since such official prescriptions such as the Maryland Environmental Site Design Manual don't recognize them. As the 2025 deadline for Chesapeake Bay TMDLs approaches too soon for the counties and states to clean up their watersheds, they are going to want to be able to claim the improvements that mycelium and biochar offer over existing practices.

Too Big to Swale

Fortunately (and wittingly) we have avoided major overflow incidents from wastewater treatment plants here in Maryland for the past several years. Easier to overlook (and we have) are nonpoint sources of water pollution, which are classified as agricultural, urban, forest, and rural, i.e. septic systems. We have become pretty wise to containing hazardous materials, but the pollutants that are choking our bays and rivers with algae are everyday elements carried in the water seeping through or running over the land. There are over 500 potential water pollutants managed in various parts of Maryland, but one ubiquitous element, nitrogen, is the major problem nutrient feeding the algae invasion of our tidal waters.

Agriculture is the largest contributor to nitrogen pollution and likely to remain so for many years. This could be because agriculture has consolidated its operations disproportionately to its proper ecological scale. Farms these days, in spite of their vast acreage, are generally family operations. Driven by globalization, agriculture has become a very competitive industry, so much that Maryland farmers would not settle for local administration of their part of the Total Maximum Daily Load (TMDL). They needed more consistent application of the standards that constitute the nutrient diet for the Bay, so TMDL for agriculture is managed at the state level.

However, it is the counties who are responsible for their reducing all of their nutrient flows (including agriculture) below set targets or risk losing their federal funding for infrastructure. In other words, the counties have accountability, but no authority for the behavior of their agricultural sectors. It should be no surprise that they have to shoot beyond their targets in the other sectors in order to make up for the lack of progress by agriculture. (I only have data from St. Mary's County, but am assuming that this subversion of local authority has the same effect everywhere.)

Am I being unfair to the agristocracy? Don't I realize they are working hard to make sure I don't go to bed hungry? No. If anybody has been unfair to them, it's the drafters of the TMDL limits. If those limits are unrealistic or biased, they should be changed. Until then, I'm sticking with my view that Ag is too big to swale and follow other Best Management Practices (BMP's) in fulfillment of their responsibility to help clean up the Bay.

Saving the Bay with Sewage

With the increase in heavy rain events (the past two weeks here, for example), the chances of having a wastewater treatment plant overflow to the watershed are growing. These incidents occur often enough for us to understand how devastating they are to the Chesapeake Bay and its tributaries. All of the efforts going into reduce nonpoint source pollution can be obviated in a day by the point source pollution of a major overflow incident. Reporting of incidents is easy to check on the state's database.

Nonetheless, the suggestions by the University of Maryland's Center for Environmental Science to reverse a decades-long trend of deteriorating conditions in Calvert County's tidal waters still emphasized nonpoint source measures, such as upgrades to septic systems and riparian buffers. That's where I come in, as perhaps the first Master Watershed Steward in Calvert County (once I complete the Watershed Steward's Academy this fall and capstone project sometime next year). The role of a Watershed Steward is to educate residents and encourage measures to mitigate nonpoint source pollution of the watershed.

Aside from the usual arsenal of methods to correct various nonpoint source problems, I'm hoping to introduce biochar in buried compost filters and bunker spawn in future projects.

Back on the topic of wastewater treatment, Biocharo  (+Kathleen Draper) posted her ideas for the top ten ways to scale up biochar production without inviting deforestation.  The number one underutilized feedstock is sewage sludge. Here in Calvert County, our dried sewage sludge is trucked off to Virginia where they find a way to turn it into fertilizer. While there may be some pollution problems with that approach, making the sludge into biochar should correct them. Not only that, we could use county-owned land right near the Appeal sewage treatment plant to set up a pyrolysis facility. Combined with pyrolysis of yard and lumber waste, this would give the county a growing income stream and save on trucking costs of sludge sent off to Virginia. Even if the local agricultural market isn't ready for it by then, there is plenty of use we could make of biochar as a stormwater management tool, while getting carbon sequestration credit for the state's greenhouse gas reduction plan.

No Free Lunch

Here in the 19th wealthiest county in the nation, we are without a metropolitan area unless you count the piece where I live, which is lumped together with part of St. Mary's county. We have a lot of farms in either county, so there should be no lack of wholesome food.

That being the case, what is behind the long-standing campaigns to grow and distribute free food to the "hunger community" in our area? Do such organized efforts alleviate long-term poverty? Do they invite outsiders desperate for food?

Two programs that stand out most are Farming4Hunger and End Hunger in Calvert County. Farming4Hunger appears to have the more honest appellation, since hunger might be a product of their efforts. Ending hunger is, of course, impossible and disingenuous as a campaign name.

The phrase "hunger community" is used in the annual report of Farming4Hunger and smacks of a caste system that implies separation of persons who rely on handouts for food. Joining the hunger community could enable a person to leave aside at least some of their struggle for basic necessities and enjoy some of the finer pleasures of life such as a home, a car, and pets.

Wait..., did I just say that a home, car, and pets are not necessities? Millions of Syrians and other migrants have come to that conclusion. The pets actually were probably temporary necessities for a meal or two, but the home and car were left behind, becoming aspirations once again as raw survival became the prime motivator.

mainly so their children may enjoy a better life. The irony is that many of them have a better chance of dealing with the economic turmoil ahead than the staid classes among whom they have infiltrated. What of those here in the 19th richest county in the USA who are insulated from those hardships. Will their children know how to dig themselves out?

Stasis. That is what is behind food giveaways. We want big ag to continue, so we have programs like Farming4Hunger that says the way to get food is through farming as we know it, and supports farmers who can't sell part of their crop on the market. We want people to think well of our charity, either as churches or corporations, so we sponsor programs like End Hunger in Calvert County which should be looking for ways to put themselves out of business, but seem interested in endless growth.

This stasis will not bring stability. Our current food system and growth paradigm is unsustainable. People need to be taught how to grow food and protect the soil. Those things, in themselves, are a struggle for anyone, but there's really no free lunch.

Fields (of Fire?)

Like a life-sized game of Stratego, the lines are being drawn between pastoral landscapes and sprawling development in Maryland. With the enactment of renewed Program Open Space (POS) legislation that expands and reclaims some of the legacy funding to create agricultural and conservation easements in perpetuity, landowners who want to dedicate some of their holdings to posterity have a little help through POS.

Quite sensibly, the Maryland Agricultural Land Preservation Program targets prime farmland and the Maryland Rural Legacy Program similarly targets areas that have high value to local ecology. For Calvert County, the latter includes an area along the Patuxent River north of Huntingtown, the area between Prince Frederick and Port Republic, and most of the Patuxent River side of the peninsula south of St. Leonard. Statewide, the targeted ecological areas form a semblance of wildlife corridors that could offer resilience to a multitude of species in this time of climate chaos.

Another recent governmental move to stymie loss of agricultural land in Calvert County was the limiting of transferable development rights (TDRs) to farmland, as opposed to the former practice of setting aside residential lots, such as the one I merged to my place of residence at minimal cost a couple of years ago.

Another factor favoring a regrarian Maryland is a faltering economy driven, in the main, by world population exceeding the carrying capacity of the planet. While suburban sprawl is projected to continue apace in our state, economic disruptions and declining resources will, at least, temper growth in the coming decades.

In fact, do you see what's happening in Europe with the wave of refugees flowing out of the Middle East? That is what our countrysides could experience in a few years with waves of unemployed, starving urbanites looking for sustenance outside of dried up food deserts. Project Open Space funds might be best spent on building campgrounds in preparation for such fiascos.

Agricultural land preservation probably won't be able to keep pace against greed and Gaia, so your best insurance at this point may be found among those who have been planning for catastrophe.  The PrepCon this weekend in St. Leonard coincides with Calvert Green Living, which I have already signed-up for. Either event may be a good use of your time if you are concerned about surviving the future.
