floodplain fill

James River floodplain south of Hugenot Bridge

I would like to throw in a different thought than what we’ve been talking about. So we’ve been talking all evening about storm water volume and flows and base flood elevations and floodway fringes and floodplains and 100 year floods and 500 year floods. And I’m well familiar with all these terms, because I spent more than 30 years running a national stream and wetland habitat restoration program across the entire United States, but I also spent over a decade surveying the biological integrity of Moores Creek. So I’m really familiar with this.

I was also vice president of the Belmont Neighborhood Association. I lived there for many years. So I know that neighborhood really well. I know the county side really well. So we’ll just establish that, but we haven’t talked about the other purposes that a floodplain provides.

It is not simply a zone where water is stored during a high water event. It does serve to dissipate the energy of flood waters. Yes, you do want them to be able to spread out and slow down, because they’re less erosive than if you push them into a funnel and let them go really fast, and that’s why we don’t like filling in the floodplain, because it constricts that flow and makes it go fast.

So we can accept the engineers analysis that they say that because this is a backwater fill situation where the water, as the Rivanna River, rises, it backs up Moores Creek, but that they have done all their calculations to say that this small area fill will not raise the base flood elevation. Fine, I’m not going to argue with that.

All right. I’m not an engineer, although I do work with a lot of engineers, but we haven’t talked about the fact that there’s other things that go on in the floodplain that are also really important.
This is habitat. This is not simply an exercise in water flow, but it is also a habitat where many different species depend on that riverine habitat.
Riverine is not a word that we’ve heard tonight that refers to that unique habitat that exists along the river. And those of you who canoe or hike or spend a lot of time in the water understand that that is a different environment than the upland environment.

So to quote the Department of Wildlife Resources, Moores Creek, which flows to the city of Charlottesville, is a tributary to the Rivanna. For decades, urbanization and manipulation have degraded the habitat and water quality of Moores Creek. And it goes on and talks about the potential for Moores Creek to be restored, and notes that multiple species of greatest conservation need listed in Virginia’s wildlife action plan could potentially live in Moores creek or the Rivanna river, and they go on to list all the different species.

Just because we have urbanized the watershed doesn’t mean we should continue to degrade it, just because we thought it was a good idea decades ago that we would put industrial uses along a river that that’s still a great idea.

Zoning can be old and stale and a bad idea, and so the underlying zone here is a bad idea, and I understand that that’s not what’s before us tonight. What’s before us is, can we let them fill in the floodplain?
So there’s a reason why the Comprehensive Plan listed this as parks and green systems. It’s because it’s a flood plain, right? That is why, and the floodplain isn’t just about floods, as I said. So I would like to mention some of the other stakeholders who are not here tonight to testify. And I’m going to save you me rattling off hundreds of species and put you in a coma. I’ll just list a few, the great blue heron, the little green heron, the salamander, the kingfisher or the red bellied woodpecker. I could go on and on with a list of aquatic and riparian species that depend on that habitat. And when we fill it and we destroy it, we diminish that.
So you might say, well, this is just a small area. We’re just going to destroy that small area, because you will destroy it when you fill it and put industrial uses on top of it. But my mom used to use this phrase. You’ve probably heard, death by 1000 paper cuts. That’s what’s wrong with Moores Creek, that’s what’s wrong with the Rivanna river. And so I don’t want to continue to do bad things just because FEMA says, If we pile a bunch of dirt tall and high enough, we’ll be outside the floodplain.
We can engineer just about anything. And I’m going to give you a quick example, I promise quick, that will help you understand the fallacy of this type of thinking.
Let’s just talk about what you can do regulatorily. We could pipe all the creeks. We could get permits from the Army Corps of Engineers. We could pipe our creeks, we could put dirt on top of them, and then, guess what? We won’t have floodplains. Then we could develop on top of all of the prior creek areas, because we could have more industrial use.

Isn’t that great?

No, it’s not great, because rivers and riparian systems provide so many other benefits, habitat areas of respite, quiet, solitude, and habitat for species that, frankly, don’t survive and thrive in other places. And so it’s up to you, if you want to take the attitude that with good engineering and enough bulldozers, we can make it work, and we can meet the federal regulations, but we’re not hitting the spirit of the law, which is to try to protect the aquatic resources of our state. So I’m just, I’m going to leave it there.
I’m opposed to this application. I’m opposed to all filling of floodplains for that reason. And there’s a reason why the Comprehensive Plan said this should be parks and green systems, and I’m sticking with the Comprehensive Plan. I’ll leave it there. I’ll only talk again, if there’s some technical thing that I want to object to, but that’s where I stand. Thank you.–Commissioner Karen Firehock December 16, 2025, Albemarle County Planning Commission meeting

Albemarle BOS will vote the fill up or down January 14, 2026. There is a petition asking them to deny this application to fill, please consider weighing in.

Inflow and Infiltration (I&I)

7. Since 2006, RWSA, the City, and ACSA have worked together to conduct flow studies, analyze flow data, assess wet weather limitations, calibrate a transmission system computer model, forecast future dry weather flows through land development projections and identify inflow and infiltration reduction goals across all sewer collection systems connected to the Facility. The goal of these projects is to assure adequate capacity in the transmission and treatment systems with emphasis on addressing unpermitted discharges. The three entities are working cooperatively to upgrade their respective sewer collection systems.

Dear Councilors,

December 8, during RWSA’s presentation on the Rivanna Pumping Station, I asked Mr. Frederick how much it would cost to repair the inflow and infiltration problems that affect our waste water system (by system I meant all waste water pipes that connect to RWSA’s waste-water treatment plants).

As I understood his response, to get to the optimal industry standard practices fix of our waste water system would cost $400 million, this is the fix where there is still I&I but it is substantially reduced. To actually fix the pipes (make them water-tight, no one does this), would cost around two billion dollars.

Rivanna runs a system, hydration and sanitation. Alas, I can’t think of an apt analogy. My not so accurate way of thinking of it…

“It is like a car. The input side, the water supply, is the gas. Water supply speeds up the economy, we can hook up houses, hook up businesses. The safety side, the sanitation, is like the brakes. The waste-water (output) side must collect and treat the effluent from these houses and businesses.”

Our region has spent a great deal of time/money studying the input side. It is my impression that we have spent less time studying the output side. If I understood Mr. Frederick correctly, a detailed study of the waste-water side would take ten years to perform. The RWSA board in the past (2005) approved an evaluation of the waste-water side, but it’s my impression that that evaluation was not equal to a detailed study.

To me, it makes sense to repair the sanitation side in lock-step with increases on the water-supply side, like balancing a budget. Hope this will happen as we move forward.

Does the 25% I&I reduction by 2020 to which we (RWSA, ACSA, CHO Public Works) have committed achieve that balance?

Thanks,

Draft Zoning Ordinance

Green energ hq downtown
Charlottesville is riding the zoning wave.

The implementation of the draft zoning ordinance will further decrease the City’s shrinking tree canopy. How low can the canopy percentage go? The code writers say we can’t ask developers for more than 20% canopy coverage, the State’s maximum requirement.
But developers and landlords can be incentivized,
the code’s green-scape zones and setbacks can be adjusted
and we can ask our City Councilors to join us in this goal.
Look at the money. The City takes in 100 million in real estate tax, the city spends one thousandth of that planting trees.
We talk the green City talk, let’s start walking the walk.
Trees and density can coexist, you just act. Plant a $10 tree in the ground, care for it, and step back.
1975 street tree plan
1975 street tree plan

In 1975 the City had a plan to plant a multitude of trees in the commons, in the right of way. In the Woolen Mills 90 trees would line East Market Street from Firefly to the Rivanna. Shade, walkability, habitat, carbon sequestration, oxygen production, stormwater control! Of the 90 trees, one has been planted at 1606 E Market.
Square that lack of follow through with the Standards and Design Manual chapter 9.6.4 which reads

“Trees must be installed along all rights-of-way regardless of location of overhead or underground utilities.”

Ask the City to plant the commons and to support designs that incorporate nature in housing plans.
I am a small scale, affordable housing provider going for 100% canopy.
We can get this done.

In the words of Wangari Muta Maathai:

“We need to promote development that does not destroy our environment.”
“Until you dig a hole, you plant a tree, you water it and make it survive, you haven’t done a thing. You are just talking.”

The story of Charlottesville’s most famous mill complex is also the tale of a section of Albemarle County, specifically the plot of land approximately one mile east of Charlottesville’s original downtown. “At that point,” wrote Harry E. Poindexter, “Moore’s Creek empties into the [Rivanna] river from the southwest, forming a narrow triangle of land which rises rapidly to a rocky crest some one hundred feet high.”– Britton
