The parcel does not have to be yours. The savings land on your statement either way. This is the last post in a series on the expense side of net operating income. The first four defined [NOI](/guide/what-net-operating-income-actually-counts), walked [the four operating bills](/guide/what-commercial-property-operating-expenses-already-include), and worked two bills where the lever already sits off the deed: [the stormwater fee](/guide/what-a-stormwater-utility-fee-is-paying-for) and [the flood policy](/guide/what-the-community-rating-system-changes-on-a-flood-policy). This one is the offer. It is written for the owner, asset manager, or controller who has read enough and wants to know what the check buys, in what unit, and where to send it. --- ## what nature based solutions for property owners actually means **Nature-based solutions for property owners** are living systems — a canopy, a floodplain, a fireshed, a wetland, a rain garden — that do work a property would otherwise pay a utility, an insurer, or a contractor to do. The phrase usually gets defined from the ecology side. On an operating statement it is plainer: a nature-based solution is a living system that lowers one of four bills. | the bill | the living system that moves it | |---|---| | Insurance | The fireshed upwind; the floodplain, wetland, or open space upstream | | Power and gas | The canopy and the park on the west side of the building | | Water, sewer, and the stormwater fee | The wetland or rain garden that holds the runoff; the headwaters above the intake | | Repairs and grounds | The slope and the channel that feed the damage | Net operating income is income after operating expenses. A lasting drop in any of those four lines raises NOI, and commercial value tracks NOI at whatever cap rate the market is using for that asset. We are not going to pick the rate or multiply a dollar into a sale price. The appraiser does that. *A lower operating bill is a higher property value.* Triple-net landlords: your tenant pays the utilities, but you still carry the insurance, most of the fees, the vacancy utilities, and the rent a tenant will pay to occupy a cheaper building. The bill is still yours to shrink. The canopy, the floodplain, the fireshed, and the wetland exist whether or not anyone buys anything. They already change your insurance, your power, your water, your stormwater fee, or your repairs. [Ensurance](/specific?from=guide) is how an owner funds the one that changes the bill. It is not the property's NOI. --- ## the parcel that moves your bill is usually not yours The stormwater fee charges your pavement. The retention that retires it can be across town. The flood premium follows the class your community earned, and the open space that earned it is upstream, on land the building never owned. In both cases the owner who benefits is not the owner who hosts the work. The host has to be paid, or the work does not happen. Your lower bill is the host's income, and their side of it is the income series, which opens with [what a hunting lease actually is](/guide/what-a-hunting-lease-actually-is). Two cases are concrete enough today to put a buyer, a number, and a unit on. The fireshed, the meadow above the well, and the slope above the only road follow the same shape and need a site before anyone should name a figure. --- ## the offer, two rows | buyer | the exposure | what we deliver | what it funds | the unit | |---|---|---|---|---| | A District of Columbia property that owes off-site stormwater retention | DOEE's in-lieu fee of $5.01 per gallon-year (effective August 1, 2026), against a retention credit priced somewhere under that ceiling | Nature-based field services on the host parcel, carried by a specific certificate on that parcel's wetland or rain garden | The retention that is the credit | Per gallon-year | | A building owner in an NFIP community whose flood premium follows the town's CRS class | A 5% to 45% discount by class on eligible policies, earned by floodplain work the building may not host | Nature-based field services plus ensurance issuance, carried by a specific certificate | The upstream floodplain, wetland, or open space that earns the class | Per flood policy | ### row one: the retention credit across town The District of Columbia regulates how much stormwater a site must retain. A regulated site that cannot retain its full volume on its own lot can meet the rest off-site, either by paying the Department of Energy and Environment's **in-lieu fee** or by buying **Stormwater Retention Credits** generated by green infrastructure somewhere else in the District. One credit is one gallon of retention for one year. The fee is the ceiling. From August 1, 2026 it is $5.01 per gallon for one year ([DOEE](https://doee.dc.gov/service/paying-lieu-fee)). The floor is DOEE's own price-lock program for new agreements: $2.03 per credit in the non-tidal MS4 area and $1.77 in the tidal area for years one through six, then $0.42 for years seven through twelve ([DOEE](https://doee.dc.gov/service/src-price-lock-program)). Everything between is negotiated between the site that owes retention and the parcel that holds the water. The floor is not the market price. We are not going to quote one. What we deliver on this row is the host side of that trade: **nature-based field services** — the rain garden, the bioretention cell, the constructed wetland that produces the gallons — on the host parcel, with monitoring built in, carried by a **specific certificate** on that parcel. The regulated property funds the condition of the place that produces its credit, rather than only buying the receipt. The unit is the one DOEE already uses: per gallon-year. The host's check for the same gallons is [what stormwater credit trading pays the host](/guide/what-stormwater-credit-trading-pays-the-host). ### row two: the flood policy and the class the town earned FEMA's **Community Rating System** discounts National Flood Insurance Program premiums in communities that do more floodplain management than the minimum. Discounts run from 5% to 45% by class. FEMA's current Risk Rating 2.0 method applies that class discount to eligible Regular Program policies in the community, inside or outside the mapped high-risk zone. The older method put the full discount only in the Special Flood Hazard Area and left Preferred Risk Policies out ([FEMA CRS](https://www.fema.gov/floodplain-management/community-rating-system)). Keeping floodplain open space open, including land left in its natural function, is one of the creditable activities. The building that stored no water still gets the class its community earned. The exposure here is a rate the owner does not set and a landscape the owner does not own. The floodplain, wetland, or open space upstream is doing the storing. The host of that land is unpaid unless someone pays them. We will not name your community's class; it is on your declarations page, or your floodplain administrator has it. What we deliver on this row is **nature-based field services** — floodplain reconnection, wetland work, the open-space condition the class credits — plus **ensurance issuance**, which structures the hold so the downstream building's payment funds the upstream place. Both are carried by a **specific certificate** on that place. The unit is per flood policy: an owner with one policy funds one share, a portfolio owner funds more. Nobody here will promise that your premium goes down. The class is the community's to earn and FEMA's to apply. What you fund is the condition the class depends on. If your carrier has already walked, [flood insurance disappearing: how to become insurable](/guide/flood-insurance-disappearing-how-to-become-insurable) is the companion. --- ## how to pay, in four steps The first two steps need no call and no account. That is on purpose. ### step 1: pull the bill, not the report For the stormwater row, that is your retention obligation in gallons from the approved stormwater management plan, or the fee line on the water bill. For the flood row, it is the declarations page on each flood policy, which shows the CRS discount if your community has one. Write the number down. It is the exposure you are already paying, and the unit you will pay in. ### step 2: name the parcel and who holds it Which rain garden, bioretention site, or wetland in the District could generate your credits. Which floodplain, wetland, or open space upstream is storing the water your community's class depends on. Then the harder part: who holds that land. A landowner, a church lot, a school, a land trust, a park district, the city. Condition is funded with the host, not around them, and it is easier to find those names now than after an agreement is drafted. ### step 3: fund the condition, not the receipt A **specific certificate** is an instrument tied to an account that stands for one named place. Funding it funds that place's condition — the retention, the storage, the maintenance in year seven — and routes proceeds to the work on it. It is not the credit, not the policy, and not the fee. The wetland is the thing. The certificate is how the owner who benefits pays for its condition. Today the parent accounts for these two rows are [`clean-water.ensurance`](/clean-water.ensurance?from=guide) for the retention row and [`risk-resilience.ensurance`](/risk-resilience.ensurance?from=guide) for the flood row. If onchain is a blocker for your treasury, notice that steps one and two never needed it. The chain is where the certificate lives and where proceeds route to the place without a fund manager between. It is plumbing. ### step 4: pick the door Three doors are open today, and a fourth is being drawn. If you are the owner, or you are speaking for the host parcel, the services on both rows — nature-based field services and ensurance issuance — are listed on [landowners](/solutions/landowners?from=guide&topic=noi-expense). Start there. If the property is a business facility and the question is how a company funds the natural infrastructure it depends on, that is [corporations](/solutions/corporations?from=guide&topic=noi-expense). The field work still happens on the host parcel through the landowners door; the corporations page is where the funding side is described. If you have the bill, the parcel, and the names, send them through [contact](/contact?from=guide&topic=noi-expense). One bill, one parcel, one unit. The fourth door is the line built for exactly this: **`neighboring parcel hold`**, under `risk-resilience.ensurance` — a certificate an owner funds on the parcel its bill depends on. It is not minted yet. It is in ideation, and the page shows it as coming soon. If this is your case, [co-create it](/specific/create?mode=suggest&agent=risk-resilience.ensurance&name=neighboring%20parcel%20hold&from=guide). A row with your bill on it is what moves it from idea to instrument. :::johnson **the first message is one bill, one parcel, one unit.** Gallon-years owed or flood policies carried, the parcel that moves it, and who holds that parcel. [send the bill and the parcel →](/contact?from=guide&topic=noi-expense) ::: --- ## what this is not It is not a replacement for DOEE's program, the NFIP, or your utility bill. Those set the fee, the class, and the rate. This funds the living system underneath them. It is not insurance advice and not a quote. We have named a ceiling, a floor, and a FEMA table. We have not named your price, and we have not promised a premium cut. It is not a credit we sell. The credit is DOEE's to certify and the host's to sell. We fund and build the condition that produces it. It is not a carbon unit stacked on the same acre, and it is not guidance on how a certificate sits on your books. That is for your controller and your auditor. --- ## frequently asked questions ### how do nature based solutions for property owners show up on an operating statement? As a smaller existing line, not a new one. The stormwater fee or retention obligation, the flood premium, the cooling load, the repair bill. The living system was already inside the bill. The owner who funds its condition moves the line. NOI rises by the lasting drop, and value tracks NOI at the market's cap rate. ### can a regulated site buy a retention credit instead of paying the in-lieu fee? In the District of Columbia, yes, for the off-site share of the obligation, under DOEE's rules. The fee is $5.01 per gallon-year from August 1, 2026. Credits trade below that at negotiated prices, with DOEE's price-lock at $2.03 or $1.77 for years one through six and $0.42 for years seven through twelve as the floor. Your obligation in gallons is on your approved stormwater management plan. ### will funding an upstream floodplain lower my flood insurance premium? Not by itself, and not on a schedule anyone can promise. The CRS class is earned by the community. The discount runs from 5% to 45% by class on eligible Regular Program policies. What the owner funds is the condition of the floodplain the class credits. Ask your floodplain administrator which activities the community is pursuing. ### what does a specific certificate do that a credit or a policy does not? A credit retires an obligation for one year. A policy pays after a loss. A certificate funds the condition of the named place the credit or the class depends on, and routes proceeds to the work on that place. It is not a credit, not a policy, and not a promise of either. ### who gets paid on the host parcel? The host. The wetland or floodplain is on their land, and the gallons or the storage are theirs to sell or to be paid for. That side is the income series, starting with [what a hunting lease actually is](/guide/what-a-hunting-lease-actually-is). You are the neighbor whose bill got smaller. ### is there a certificate for this today? The parent accounts are live: [`risk-resilience.ensurance`](/risk-resilience.ensurance?from=guide) and [`clean-water.ensurance`](/clean-water.ensurance?from=guide). The line drawn for this exact case, `neighboring parcel hold` under `risk-resilience.ensurance`, is coming soon and open to [co-create](/specific/create?mode=suggest&agent=risk-resilience.ensurance&name=neighboring%20parcel%20hold&from=guide). --- ## sources [FEMA Community Rating System](https://www.fema.gov/floodplain-management/community-rating-system) — CRS class discounts, 5% to 45%, SFHA and non-SFHA treatment, Preferred Risk Policy exclusion [DOEE: Paying In-Lieu Fee](https://doee.dc.gov/service/paying-lieu-fee) — in-lieu fee of $5.01 per gallon for one year, effective August 1, 2026 [DOEE: SRC Price Lock Program](https://doee.dc.gov/service/src-price-lock-program) — price-lock floors for new agreements: $2.03 non-tidal MS4 and $1.77 tidal for years 1–6, $0.42 for years 7–12 --- ## the series The expense side, where the living system already sits in the bill: 1.
