In the fall of 2020, there was an urgency in the Douglas County Courthouse about flooding.

A building roughly the size of a football field — home to the offices of a sod shop — had been built in the rural area north of North Lawrence, sparking concerns that other big buildings would follow and that the flat ground would become even more flood-prone than it already is.

So, in lightning-speed time — by government standards — county staff had created and county commissioners had approved stringent stormwater standards for much of the rural area north of North Lawrence.

Just a little more than two months had elapsed from the approval of the sod shop building to the creation of the new regulations.

Then, urgency hit a roadblock: a bureaucratic mistake.

The county’s staff failed to complete the final step in the process for the regulations. The resolution that county commissioners approved on Nov. 18, 2020, called for the regulations to be added to the County Code, which is the legal document that lists the multitude of regulations that individuals and businesses must follow on any number of matters.

Inserting the regulations into the code would give them the sharpest teeth possible and, from a more practical standpoint, it would be the easiest way to ensure that builders of future projects knew the regulations existed. Architects, engineers and others frequently consult the code as they develop projects.

Instead, the section of the code meant to house the stormwater regulations sat empty on the county website that houses the online version of the code for more than three years — until earlier this week, when the county added the regulations to the code after the Journal-World inquired about the regulations’ absence.

“It was an error that the code was not updated,” county spokeswoman Karrey Britt said in an email response on Tuesday to Journal-World questions.

It is an error that could have major ramifications for the proposed $234 million Kansas Sky Energy Center, a massive utility-scale solar farm that would occupy approximately 600 acres of land in the area north of North Lawrence.

Opponents of the project — who have objected to it, in part, over concerns that its 237,000 solar panels will create area flooding problems — are now questioning whether the County Commission’s approval of the solar project should be set aside due to the error.

“It is a legitimate question to ask whether the entire project should go back to square one,” said Nancy Thellman, a former Douglas County commissioner who lives in the rural area and has been a vocal opponent of the solar project.

This site north of Lawrence is the proposed location of the Kansas Sky Energy Center solar project.

To start the approval process over would mean that the developers of the project — a subsidiary of Shell Energy that is working on behalf of the regional electric utility Evergy — would have to go all the way back to the Lawrence-Douglas County Planning Commission for a new public hearing. The project then would have to go to the Douglas County Commission again for a new hearing before that body. A restart would add months to the project. The last County Commission meeting on the project, by itself, lasted nearly 10 hours.

It is a step that may need to be taken, though, if the county wants to comply with its own process for approving conditional use permits, which is the type of permit that county commissioners approved for the Kansas Sky Energy Center project.

One of the mandated considerations for the County Commission in approving conditional use permits is to consider “whether the proposed use complies with all applicable provisions of these regulations,” which refers to the county code.

The question that hangs over the project now is: How could the County Commission — or its advisory body, the Planning Commission — meet the obligation of determining whether the project complied with regulations, when some of the required regulations were never listed in the code to begin with?

In other words, do you have to first be aware of the regulations before you can determine whether a project complies with them?

But that is not the only question now attached to the proposed solar project. The Journal-World also asked the county whether the solar project would be required to meet those stormwater regulations approved in 2020. While the solar project has received approval for its conditional use permit, that approval is contingent upon the developers submitting a final stormwater management plan for the solar project. Britt, the county spokeswoman, essentially said the project would not be required to comply with the county’s approved stormwater regulations.

“The scale of this project will require a completely different technical approach,” Britt said via email.

However, it is unclear what authority the county has to simply exempt the solar project from the county’s approved stormwater regulations. The first sentence of the approved regulations states that conditional use permits “must meet this standard to control stormwater runoff from impervious surfaces within Maple Grove watershed,” which is a technical name for the area in which the solar project is proposed.

The resolution that created the regulations contained no specific provision for an exception to the regulations.

Attempts to get more information from the county have not yet been fully successful. The Journal-World on Thursday morning asked for a follow-up interview with county officials to inquire about both the county’s authority to exempt the solar project from the regulations, and also for the county’s view on whether the error that left the regulations unpublished was fatal to the CUP approval process. The county has not yet made an official available for an interview.

The county at about 10 a.m. on Friday provided an emailed response that partially answered some questions that the Journal-World shared Thursday evening with the county via email. In that Friday response, the county said it believes that the stormwater plan that will be approved for the solar project will meet the intent of the 2020 approved stormwater regulations.

Britt, the county spokeswoman, also said in the emailed response that the county believes the ultimate stormwater plan for the solar project will be more stringent than what was possible under the 2020 approved stormwater regulations. She said the 2020 regulations are “not adequate for a project of this scale.”

The county said its determination is that the conditional use permit for the solar project met the county’s prescribed approval process. The county doesn’t believe the solar project needs to start the process over, and the county contends the 2020 approved stormwater regulations simply don’t apply to the project.

However, the county did not point to any provision — neither in the county’s general code nor in its specific solar regulations — that nullifies the plain language of the 2020 stormwater regulations. Those regulations state all conditional use permits in the Maple Grove watershed — which everyone agrees the solar project is in — “must meet this standard to control stormwater runoff…”

Instead, the county pointed to a provision in the solar regulations that lists the types of stormwater documents that must be included in the application materials for a large-scale solar project. The part of the solar code the county pointed to does not place any requirements on how the county must review stormwater issues, but rather merely identifies which documents must be submitted for an application to be accepted. The provision is silent about the approved 2020 stormwater regulations.

Opponents of the project said the county’s approach to the stormwater issues has been emblematic of the entire approval process for the solar project.

“It is the same as them not using any of the other information, studies and master plans that they have,” said Ted Boyle, president of the North Lawrence Improvement Association, who has argued North Lawrence is at severe risk of increased flooding as a result of the solar project being built upstream of the city. “They have not adhered to any of it at all.

“They have just bullied and pushed this solar farm in here.”

Thellman, who was on the County Commission in 2020 when the stormwater regulations were approved, said the failure to publish the regulations was a “really serious wrinkle in this whole process.”

“Publishing this material years later — after (the newspaper) made the county aware of it — is a problem,” Thellman said.

But she contends it has been one of many problems in the approval process.

“That is one of the things that has been so troubling about this project,” Thellman said. “It seems to have taken a special, privileged path from start to finish to clear the way for it to move forward.”

The boundaries of the Kansas Sky Energy project are shown. Also shown are soil types in the project. Areas shown in red are soils that are rated to have high stormwater runoff potential.

Thellman said this project should be one that the county should have processed in a manner that is beyond reproach because of its size and impact on the countryside. The project would add nearly 8 million square feet of solar panels to the Kansas River valley. From a size standpoint, that is the equivalent of about 4,000 homes that are an average of 2,000 square feet in size.

While few people contend the solar panels would create the same stormwater impact of that many homes — the ground beneath the solar panels won’t be covered in concrete, for instance — there has been disagreement over how much stormwater runoff the project will create.

An investigation by the Journal-World last month reported that the county does believe the solar project will increase the amount of runoff that currently exists in the area, but county officials contend the runoff can be managed with a few detention basins and other methods. But the county engineer — a stormwater engineer by training — acknowledged that if the county is wrong in its assessment, it would create significant new flooding risks for North Lawrence, given that essentially all water from the solar project that is not able to be absorbed into the ground will flow through the developed portions of North Lawrence.

“If this were a small, insignificant project, you might think bad process, no harm done,” Thellman said. “But it can’t be said enough times that this is the biggest project that Douglas County has ever taken on.

“If ever there was a project to give extra scrutiny and the highest requirements, this would be it,” Thellman said.

A look at the 2020 approved stormwater regulations

A key vote of the Douglas County Commission is still required before the $234 million Kansas Sky Energy Center solar project in rural North Lawrence can move ahead.

When that vote will happen, though, is still anyone’s guess.

County commissioners must approve a stormwater plan for the development before construction can begin on the project, which will add nearly 8 million square feet of solar panels on farm ground that mostly surrounds the Midland Junction area north of North Lawrence.

A spokeswoman for the county said via email this week that there is no update to provide on how that stormwater plan is progressing or when it might come to the County Commission for a vote.

Exactly what set of standards the plan will be required to meet is now unclear as well. As the Journal-World reported, Douglas County officials this week said the solar project — the largest development project ever considered by the County Commission — won’t be required to meet a special set of stormwater regulations that the county approved for the flood-prone area in 2020.

Exactly what stormwater standards the project will be required to meet hasn’t been announced by the county. Instead, the county engineer has said the final stormwater plan will ensure that the amount of stormwater that runs off the site of the solar farm will be no greater than what occurs today without a solar farm.

However, the approved 2020 stormwater standards are designed to accomplish the same thing — no net increase in stormwater runoff from any project. The approved 2020 standards list nine requirements, or technical strategies, that a development must use in order to ensure that the overall goal of no increased runoff is met.

The county has not provided much detail about why the solar project can’t use the 2020 approved stormwater standards.

“The scale of this project will require a completely different technical approach,” county spokeswoman Karrey Britt said via email. That was the county’s only response to a question about whether the solar project would be required to meet the approved 2020 standards.

Here’s a summary of the standards approved in November 2020.

• “Site plans, conditional use permits, subdivisions and other land developments subject to approval of the Board must meet this standard to control stormwater runoff from impervious surfaces within Maple Grove watershed,” the first sentence of the standard reads. During the Nov. 18, 2020, meeting, commissioners actually had a conversation about the difference between the words “should” and “must” in the regulations. While talking about a different sentence in the regulations, County Commissioner Patrick Kelly said the word “should” seemingly gave the commission latitude to deviate from language in the resolution, while he said the use of the word “must” in a sentence of the resolution “probably would have tied our hands.” The resolution that created the stormwater standards contains no specific provision on how the county can decide that a project is not required to comply with the stormwater standards.

• Any project must include enough stormwater detention basins to contain any new stormwater runoff created by a new development. The project must be designed to handle excess runoff from a 100-year storm event

• The regulations list the specific formulas, databases and other technical standards that must be used when calculating how much new runoff a project will create. Britt said via email on Friday that the calculations that are being used to create the solar project’s final stormwater plan are more restrictive than the standards required in the 2020 approved regulations.

• If soil conditions allow, stormwater basins must be designed to allow runoff to infiltrate into the ground within 96 hours.

• If the 96-hour limit cannot be met, the regulations provide standards on how stormwater basins are allowed to drain.

• The regulations require that “the entire developed site must drain” to the storage basins for the project. In other words, the runoff from the project can’t go directly into creeks or streams. That may be a tough standard for the solar project to meet. The project’s preliminary stormwater plan did not include any storage basins for the solar panels. County Engineer Chad Voigt rejected that plan, and has said some storage basins would be required. However, it is unclear that all runoff from the solar panels would be required to drain to the basins.

• The standards discuss grading requirements for the site to help limit flooding in instances where the storage basins are full of water.

• The regulations require specific notes be placed on the site plan for the project which commit the developers to doing certain maintenance work on the storage basins to ensure they maintain their capacity to detain water, among other items.
