Do you have everything you need to apply for a stormwater permit? Use the I Have a Project questionnaire to be sure!

By Matt Christian

Winter is upon us. When we’re not thinking about snuggling up to a fire to stay warm, planning skiing trips, drinking hot chocolate, and cleaning snow off our driveways, we begin to start thinking about projects we’d like to do when the weather breaks. This could involve building something on your property; maybe an addition, new garage, pole barn, shed, or possibly a pond. If you are thinking about a project like this, you may need to contact our office about obtaining a Stormwater Permit.

Richland SWCD implements the Stormwater Management and Sediment Control Regulation program on behalf of the Richland County Commissioners. This program was created to ensure that disturbed soil from construction stays on site and does not run off the property. It also considers how rainwater will flow off of new buildings, driveways, and concrete and that it outlets in a way to encourage water to soak into the soil onsite.

If you need a Stormwater Permit, we want to make sure the process is as smooth and painless as possible. We have two technicians that are happy to assist you with the permitting process, Sam Foley and Zoe Baumberger. A few years ago, we developed an interactive questionnaire that will assist you in making sure that you have everything you need before you come see Sam or Zoe, It is called “I Have a Project” and it’s located on our website, Richlandswcd.net (linked below).

It asks you a series of questions about your project then provides a list of all the other permits or documents you will need to get before you apply for a Stormwater Permit. It will even prepare you whether to expect a permit fee or not. The goal of “I Have a Project” was to inform applicants of what they needed before coming in. One of the most frustrating things for applicants is to make the trip to the office to get the permit only to find out they actually have to leave and go acquire a septic permit first, for example, then make another trip back to the office.

So, if you’re looking to complete a project in Richland County, please check out “I Have a Project”. There are a couple of different ways to find it on our website:

2025 Stormwater Numbers

Updates from the final quarter of 2025 and advice on preventing runoff through snow melt.

By Sam Foley

Our final quarter of the year brought in fewer permits than the summer months, but that’s to be expected. Despite the unpredictable winter weather, we still issued 8 permits for commercial projects and 59 residential permits between October 1 and December 31, 2025. Of those 59 residential permits, 41 of them were some sort of exemption.

In 2025 we issued a total of 385 stormwater permits and performed over 700 site inspections.

Please remember, if you are moving soil in the unincorporated areas of Richland County you need to consult with us about a stormwater permit to ensure you are following the Stormwater Management and Sediment Control Regulations of Richland County. Reference Matt Christian’s article on what information and documents you need to obtain a stormwater permit.

How about a stormwater minute? Even though colder weather is here, and the ground is mostly frozen, you can still find Zoe and I out and about performing site inspections. Frozen ground could maybe be considered temporarily stabilized, but as soon as the thaw comes, the potential for runoff and erosion concerns is very high! Snow melting can contribute to runoff volume and if you are unable to achieve permanent stability in the fall, chances are you are going to see some erosion and soil loss as the ground thaws. Please ensure that you are monitoring site conditions and add the appropriate sediment controls as needed. If you need advice on managing your site, please give us a call, we are happy to help. Be sure to have a plan in place for finish grading and seeding as the warmer weather returns in the spring. Please keep in mind that we don’t consider the permit requirements completed until your site reaches permanent stability.

Harvesting the Numbers: Fall Stormwater Update

Stormwater permit numbers and soil stabilization requirements.

By Sam Foley

Our third quarter of 2025 brought in quite a few stormwater permits. We issued 5 permits for commercial projects between July 1 and September 30. We also issued 106 residential permits during that same time frame with 63 of those being some sort of exemption.

Please remember, if you are moving soil in the unincorporated parts of Richland County you need to consult with us about a stormwater permit to ensure you are following the Stormwater Management and Sediment Control Regulations.

And now for a Stormwater Minute: Did you know that the county’s Stormwater Management Regulations have a section outlining the requirements for soil stabilization? We’ve defined soil stabilization as “Vegetative or structural soil cover controlling erosion, including permanent and temporary seed, mulch, sod, netting, jute mat and silt fence.” Temporary stabilization should be provided for rough graded areas that will be idle for longer than 30 days. Upon achieving final grade, permanent stabilization should be installed within seven days. Any portion of a site within 50 feet of a stream, wetland, or other body of water should be stabilized immediately. Be sure to use appropriate measures for the time of year, site conditions, and length of use. If you need advice on seeding schedules, we are always happy to help. As summer ends and cooler weather rolls in, it is an ideal time to plant grass seed and stabilize your site. Please plan accordingly to prevent soil loss and stay in compliance with the Stormwater Management and Sediment Control Regulations.

To Soak or Not to Soak

Summer storms and impervious surfaces mean faster runoff. Check out our updated data and tips to help slow the flow!

The spring rainy season has passed and now we’re in the summer season where rains can be less frequent, but a summer thunderstorm can be quite intense and can dump a lot of rain in a short amount of time. These rain events are needed but relate to a term we use here in the office a lot, impervious area!

Impervious areas are areas that are man-made and do not allow water to contact the soil. Instead, this water is forced to flow off this impervious area, eventually to some type of outlet. A typical outlet is a lawn, road ditch, street, storm sewer or stream. This means that the rain water now gets to an outlet a lot faster than it used to.

Imagine an empty lot full of trees, shrubs and grass. At this point, the whole lot would be considered pervious area. Pervious meaning that when rain falls on the land, it now can penetrate or enter the soil. Some of the water is taken up by the many plant roots. More water soaks into the soil, being absorbed as it goes down. It makes it’s way down by pores & holes in the soil made by old roots, earthworms, animals and insects. Eventually the rain would soak all the way to the water table and some would then be carried to streams. Some water makes it down even further to the ground water. This water has now been filtered by the soil and has recharged our ground water resources. Once the soil has become totally saturated, additional rain would not be absorbed and that water would become runoff, but as you can see it would take quite some time and a lot of water to get to this point.

Now, imagine this empty lot has been sold to someone who wants to build a new home and garage. The soil will be disturbed and a portion of the lot will be developed into impervious area by way of roofs, driveways and sidewalks. That rain water will no longer make it to the soil. Since this water has nowhere to soak, it adds up fast! This becomes runoff immediately.

In the past, the accepted method to deal with impervious runoff was to gather it, put it into a tile or pipe and outlet it directly into a street, road ditch, stream or neighboring property. After many years and thousands of acres of impervious areas developed, it was observed that the rivers and streams began to widen, erode and change course drastically. This was due to all this impervious runoff getting to the stream too quickly and the stream was just adjusting to handle all of this rapid runoff.

Now we’ve learned from our past mistakes, and our focus is to slow impervious water down, giving streams time to handle the runoff. We’re not saying that development can’t happen, we’re saying impervious runoff needs to be managed.

The Stormwater Regulations of Richland County were developed for this purpose. Richland SWCD administers the Stormwater Regulations for the Richland County Commissioners.

On residential sites we encourage applicants to outlet water from their impervious areas onto the soil, on their own property, giving this water a chance to soak into the soils as it did before development. This unlocks the benefit of water soaking into the soil but also slows the water so it’s not getting to the stream too quickly.

On commercial projects, engineers design practices to hold back the very large amounts of impervious runoff that large commercial sites generate. These can consist of detention/retention basins, pervious pavement, rain gardens and underground detention.

Since Richland SWCD began administering the Stormwater program in 2000, we’ve been tracking the amount of impervious areas being developed in square footage. We’ve tracked residential, commercial and agricultural projects and we’ve recently updated our website to include this data all the way to 2024. Please check this out on our website.

If you want to do your part in reducing impervious runoff, you may want to look into installing rain barrels and/or rain gardens on your property. You can also change your downspouts so that they outlet onto your lawn. Even small steps like these help protect our streams and reduce the impact of impervious surfaces in our community.

Stormwater Season in Full Swing: Are You Covered?

Find out if your site is in compliance with the local stormwater regulations plus permit numbers from the second quarter.

Our 2nd quarter of the year brought in many stormwater permits. We issued 14 permits for commercial projects between April 1, 2025 and June 30, 2025. We also issued 72 residential permits during that same time period with 48 of those being some sort of exemption. Please remember, if you are moving soil in the unincorporated areas of Richland County you need to consult with us about a stormwater permit to ensure you are following the Stormwater Management and Sediment Control Regulations of Richland County.

And now for a Stormwater Minute: Did you know that Agricultural projects are NOT exempt from the county’s Stormwater and Sediment Control Regulations? While agricultural construction is typically exempt from building and zoning regulations (still check in with each of these departments if you have an ag project), it is still subject to stormwater permitting requirements. We require site plans and the permit application to be submitted to our office. We inspect projects that go over the 2,000 square foot threshold outlined in the County’s regulations. Stormwater Permits for Agricultural projects are fee exempt though and never cost the farmer anything.

Stopping the Slide: How to Stabilize Streambanks and Prevent Erosion

Springtime brings back warmer temperatures, green plants, beautiful blooms – and unfortunately heavy, damaging rain events.

Springtime brings back warmer temperatures, green plants, beautiful blooms – and unfortunately heavy, damaging rain events. Sometimes an after effect of these heavy rains is streambank erosion. This occurs when heavy rains make their way to streams, dramatically increasing the speed and force of the water. These flow velocities can be too much for the streambank and sections of the soil can be eroded away. In some instances, erosion is significant enough to remove a portion of the property and establish a new streambank edge. Another detrimental effect of this erosion is that soil is washed into the stream and suspended in the water column, which is a type of pollution (See MS4 Update: Why Soil Matters More Than You Think).

There are actions that can be taken to protect stream banks. Mechanical methods can be installed, this would include placing materials such as large rip-rap stone, timber pilings, stream rock veins, rock gabion baskets or retaining walls made of treated timber or metal sheet piling to hold the bank in place. These methods would offer immediate relief, but they can be extremely expensive and if not professionally designed and installed, they could fail in short order.

Another action that should be considered would be planting live trees and shrubs. This method requires a little forward thinking and is not an immediate fix, but it is much more affordable and if established properly, could offer a very long-term solution. Trees and shrubs along stream corridors offer their live root systems to hold soil in place and are called Riparian Buffers. The root systems of vegetation resists the force of storm surges in the river and keep the streambanks and the soil in its place.

There are many types of trees and shrubs that would be suitable for this purpose, but I would like to highlight one tree in particular for landowners to consider – the American Sycamore tree. The American Sycamore is a native tree and can be recognized by its mottled brown, gray and white bark that can look like a camouflage pattern. It is typically found growing wild along stream and river corridors and has the largest circumference and leaves of any hardwood tree in North America. It is a large tree with a potential diameter of greater than 10 feet, and a height range between 80 and 140 feet! They are a long-lived tree as well. A living tree was cut down in southeastern Indiana in 1970, it’s diameter was more than 7 feet, and it was found to be 430 years old!

As far as stream benefits, here’s what the Sycamore can offer. Their massive root systems not only hold and secure stream banks, but they also filter out sediments and other surface pollutants from the stream. These root systems also create flow eddies in the stream which can reduce erosive flow and offer resting areas for fish from strong flow currents. Their large size can offer shade to the stream channel too. This cools the water which increases dissolved oxygen and inhibits nuisance algae. The tree itself offers multiple wildlife benefits, it can provide cavities for shelter along with roosting and nesting sites for birds. The Sycamore is the preferred tree by Bald Eagles and the canopy of a mature tree can support a 2,000-pound Bald Eagle nest!

So, the next time you have a chance to drive or hike next to a stream, take a look and see if you can spot this amazing tree. Notice how the roots are securing the streambank and take a peek into the canopy and see if you can spot an eagle’s nest. I hope this will give you a new appreciation for the Sycamore and consider it an option as a streambank stabilization technique.

Quarter One Stormwater Update: Permits Issued and Compliance Reminders

Please remember, if you are moving soil in the unincorporated parts of Richland County you need to consult with us about permit requirements…

Our first quarter of the year was very active for Stormwater Permits. We issued 12 permits for commercial projects between January 1, 2025, and March 31, 2025. We’ve also issued 59 residential permits during that same time period with 30 of those being an exemption.

Please remember, if you are moving soil in the unincorporated parts of Richland County you need to consult with us about permit requirements to ensure you are following the Stormwater Management and Sediment Control Regulations. Let’s work together to be good stewards of our county’s natural resources!

On August 8, we presented information on Richland County’s stormwater permitting process during a Lunch & Learn hosted by the Mansfield Association of Realtors. The purpose of the Lunch & Learn was to educate local realtors on the intricacies of permitting in the county so that they may better assist their clients.

Also presenting was US Army Corps of Engineers Realty Specialist Eric Dowing who provided participants information on the Army Corps’ flowage easements. According to the Army Corp, flowage easements are non-federal lands where the U.S. Government has acquired rights to back up water if necessary (to a certain elevation).

Flowage easements exist in Richland County and stretch for miles upstream from the Charles Mill and Pleasant Hill Dams. Knowledge of flowage easements is critical because land use within the easement is heavily restricted. Thank you to the Mansfield Association of Realtors for hosting the event and allowing us to speak with their members about permitting in Richland County!

Why Are We So Blue?

We recently traded our old, yellow, high-visibility vests for new blue ones with our logo! These vests will help keep us safe and stand out when we do stormwater inspections or other fieldwork.

Our Stormwater Technicians regularly inspect permitted projects, visiting projects in all 18 townships about once every other month. They also inspect storm sewer outfalls.

If you see the blue vest, know that Richland Soil & Water is hard at work!

Busy With Stormwater Permitting

This quarter, our office issued 87 residential permits (this includes all residential & agricultural permits, fee exemptions, and permit exemptions), up from 66 last quarter.

We also issued 6 commercial permits. We’re as busy as ever.

Successful Screenings – MS4/NPDES Update

This quarter we focused on conducting dry weather screening of stormwater outfalls in Madison Township as part of our ongoing MS4 efforts. We successfully screened 4 outfalls for signs of illicit discharge or pollution.

These screenings are an essential part of our work to ensure stormwater runoff remains clean and free from harmful pollutants. We only have 6 more dry weather screenings to complete this permit term!

Graphic showing the number of screenings that have been completed and remain. 6 occurred in Madison with 4 remaining. 1 in Springfield with 1 remaining. 3 in Washington 1 remaining. No screenings needed in Mifflin.

The MS4/NPDES permit is a crucial regulatory measure designed to manage and reduce pollution from stormwater runoff in urbanized areas. For more information, click on the links below.
