Two new detached homes in Lynden can be the same size, have the same finishes and carry the same asking price. Why does one start out with an extra $15,589 in city fees? The answer is where it sits. Under the fee schedule the City of Lynden put into effect on July 1, 2026, a new detached home pays a transportation impact fee of $2,765 in most of the city. In the Pepin Creek Subarea on the east side, between Benson Road and Double Ditch Road, the same home pays $18,354.
In a hot market, buyers rarely see that kind of cost. It gets built into the price and nobody asks about it. Lynden's market in fall 2026 is not hot, and that makes the fee something a buyer can look at.
The gap, line by line
The city sets both fees from the same starting point, PM peak-hour vehicle trips. Pepin Creek's rate per trip is far higher, and every housing type inherits that gap.
| Housing type | Citywide fee | Pepin Creek Subarea fee |
|---|---|---|
| Per PM peak trip, the base rate | $2,973 | $19,726 |
| Detached home | $2,765 | $18,354 |
| Accessory dwelling unit | $1,382.50 | $9,172.50 |
| Multifamily unit, attached or stacked | $1,546 | $10,258 |
| Senior housing unit | $743 | $4,931.50 |
The ratio comes out to roughly 6.6 to 1 for every type. Townhomes and ADUs don't escape it. A buyer comparing a new townhome in Pepin Creek with one across town is looking at a $10,258 fee against a $1,546 one. Transportation is also only one fee. School impact fees, for example, are set citywide at $4,661.50 for a single-family home with three or more bedrooms. That fee doesn't change with location.
What the extra money is meant to build
The higher rate exists because Pepin Creek needs infrastructure the rest of Lynden already has. Lynden's 2027–2032 transportation program, approved June 1, 2026, groups the subarea's projects together. Several of them list "Developer Mitigation" as part of the local funding.
- Pepin Creek main stem, phased relocation: $8.95 million, from Isom School to a new east/west creek corridor.
- East/west Pepin Creek corridor: $3.44 million, running to Double Ditch Road and including a culvert at Double Ditch.
- Double Ditch Road: $6.473 million to widen it to city arterial standard from Main Street to the future parkway, with water and sewer trunk lines included.
- Pepin Parkway bridge: $3.86 million to carry the new arterial over the relocated creek.
- Pepin Parkway arterial: $8.375 million from Benson Road to Double Ditch, with a stormwater median and restricted driveway access.
Together these listed components come to about $31 million. The program says the city "may apply" for a federal RAISE construction grant in 2026 to build them, and no award has been announced. The $2 million RAISE grant Lynden received in January 2025 was for planning and design. The Lynden Tribune reported that Mayor Scott Korthuis described it as money to prepare for the relocation, with construction phases still to come.
Pepin Parkway is a design compromise. According to the city's Pepin Creek Subarea Plan, last amended in July 2021, the full creek realignment and a stormwater bypass were both too expensive to build. Staff drew up a smaller version called "Pepin Lite." It shrinks the realignment, puts traffic on one new diagonal arterial, and puts off improvements to the north end of Double Ditch Road and the south end of Benson Road.
The bridge that showed how the bill gets split
The clearest example of who pays came in March 2025, over a bridge on Pine Street. The Lynden Tribune covered the council's debate and called it the "bridge to nowhere" saga. The bid for the bridge and related work was $4.4 million. The city planned to borrow it on a 20-year loan, with impact fees and Transportation Benefit District revenue covering the payments. On March 17 the council voted the bid down. Members questioned how it would be paid for and how much impact-fee revenue the city would actually collect, since some fees would be traded to developers in return for building road extensions.
At a special meeting afterward, the council voted unanimously to reconsider. Mayor Korthuis said that if voters did not renew the Transportation Benefit District, the 0.1% portion the council can approve without a public vote would still cover the bridge. The contract was also changed so that developers would build about 450 feet of the creek, which the mayor said would save the city just under $1 million. The council awarded the bid to DeKoster Excavating and gave the construction management contract to Reichhardt & Ebe Engineering.
In the Tribune's account, Council Member Brent Lenssen put the cost of waiting this way:
"We're basically getting a road bridge for another $400,000 at this point."
He also said he would have a hard time voting for other Pepin Creek projects that rely on impact fees. That matters for buyers, because it means the council has openly argued about how much of Pepin's infrastructure the city carries and how much new development carries. That split shows up in what builders pay.
Lynden uses the same "growth pays it back" approach outside Pepin Creek. The Tribune reported that a sewer pump station near the Guide Meridian and Bay-Lyn Drive cost $2,360,196 in reimbursable costs. About $641,000 of that is the city's share for future capacity, and the rest is spread across 31 parcels through a latecomer agreement, at amounts from $7,000 to $604,000 each. The council scheduled a public hearing on the assessment for October 19.
What's on the ground and what's still on paper
A fee pays for future infrastructure, and in Pepin Creek the pieces are at very different stages:
- SR 546/Badger Road–Benson Road roundabout: finished. WSDOT closed the intersection June 21–27, 2026, and its project page shows the work completed in July 2026.
- Pepin-Pine Bridge: under construction as of the city's October 8, 2025 projects update, with girders scheduled to arrive October 3, 2025. No completion date has been published.
- Benson Road improvements: uncertain. The same update said federal stormwater rules on 6PPD-quinone, a tire chemical, could require a federal consultation lasting two to five years, and called construction funding "presently uncertain."
- Pepin Parkway, its bridge, and the main creek relocation: listed in the 2026 program, with construction tied to grant money the city may apply for.
Housing in the subarea is mostly proposals so far. The best-documented one is Summit View Village at 8683 Benson Road, a nine-acre multifamily project from Mountain Summit Ventures, LLC. A March 25, 2026 legal notice in the Lynden Tribune showed the plan revised from up to 80 units to up to 102. The city issued a revised environmental determination on March 19, 2026, for four- and six-plex buildings. An environmental determination is a review step. It does not mean construction has started. Each of those units would fall under the $10,258 multifamily rate.
Why September's numbers change who absorbs the fee
A builder can only pass a cost on to buyers if they will pay it. Right now, resale homes in Lynden give buyers plenty of other choices.
NWMLS figures for September 2026 show Lynden, NWMLS map area 885, with 87 active residential listings at the end of the month, up 47.46% from September 2025. Only 9 homes closed that month, down 50%. That works out to 9.67 months of inventory, almost twice Whatcom County's 4.96. The median closed residential price in Lynden was $623,000 in September 2026, down 5.18% from a year earlier. Countywide, the median rose 2.69% to $620,250.
New construction has slowed even more. NWMLS's September 2026 Whatcom County report shows no new-construction residential closings in the Lynden area for the month and 4 for the year through September. The same period in 2025 had 14. Countywide, new-construction closings dropped from 29 in September 2025 to 20 in September 2026.
Here is how these numbers connect to the fee. A Pepin Creek builder pays about $15,600 more per detached home in transportation fees than a builder elsewhere in Lynden, and resale homes elsewhere in town don't carry that cost at all. With close to ten months of resale supply, a buyer has time to compare. That limits how much of the fee a builder can add to the price and still sell, especially when new-home closings in the area are this slow. Nothing published shows how much of the fee ends up in Pepin Creek prices. The city fee schedule and the NWMLS breakouts are both public, though, so a buyer can come to the table with the same numbers the builder has.

Frequently Asked Questions
Does a buyer pay the transportation impact fee directly? The city's fee schedule lists it as a per-unit impact fee on new residential development. How much of it shows up in a home's price comes down to how the builder prices the home, and nothing published tracks that. The city's unified fee schedule lists the current amounts.
Does the Pepin Creek rate apply to resale homes? The schedule lists it as an impact fee on new development, priced by housing type. It does not list a fee for resale transactions.
Is the Pepin Parkway funded? The 2026 transportation program lists the parkway and its bridge, with developer mitigation among the local funding sources and a possible federal construction grant application in 2026. An award has not been announced.
If you're comparing a new home in Pepin Creek with a resale home across town, the gap in fees is worth seeing on paper before you write an offer.
