Bettendorf council debates annexation of roughly 420–450 acres east of Kriswell as staff outlines $15 million sewer plan

Bettendorf — City staff on Monday presented a proposed voluntary annexation of roughly 420–450 acres east of Kriswell, with consultants and staff telling the City Council that the development could add about 500 housing units and, under current modeling assumptions, generate more in public revenue than the city would spend to provide services.

Mark Hunt, director of community development, said the area under discussion lies around Forest Grove Road, Kriswell and Wells Ferry and is largely agricultural now; staff’s concept applied a mix of mostly single-family homes and some townhome-style units with limited edge commercial uses. “We’re talking Forest Grove Road … I’m going to say 450 to 420,” Hunt said while describing the area and the voluntary-annexation approach.

Why it matters: staff and consultant modeling put the annexation’s estimated sewer cost at about $15 million but found general-fund revenues from new development would materially exceed incremental operating costs over either a 10‑ or 20‑year horizon. Consultants also modeled several financing approaches — spreading costs across all sewer users, creating a special-user charge or a sewer district, or relying on developer contributions — and advised the council that a state revolving fund (SRF) loan remains a realistic avenue for lower-interest borrowing.

Key facts and figures - Proposed area: ~420–450 acres (staff estimate presented to council). - Preliminary development yield used in models: roughly 500 housing units (mix of single-family and townhome styles), with some small commercial at edges. - Sewer capital estimate discussed in the meeting: approximately $15 million for trunk and connector work. - Modeling assumption for a representative market-price mix: staff used a baseline average home value near $970,000 based on developer input; consultants said even a 30% reduction in that price point would still leave modeled revenues above costs in the study’s scenarios. - Timing: consultants and staff estimated design, easement acquisition and construction would take roughly 2–2.5 years before major sewer capacity was in the ground.

Consultant takeaways and finance options Aaron Gruin (Gruin & Gruin) and Mitchell Eshweiler (Baker Tilly) answered detailed questions about inputs and sensitivity. Gruin said staff and the consultant team relied on developer conversations and known land/zoning patterns to set home-price assumptions; He added, “If you simply assumed it was 30% less, the main item would be property taxes … but there’s more than a 30% difference in revenue over costs in the summary tables.”

On interest costs, consultants modeled a conservative 4% borrowing rate when SRF (state revolving fund) financing is not assumed; Mitchell Eshweiler told the council that, depending on market conditions and credit, “you’re probably looking at low fours” for a 20‑year sewer revenue bond. Staff and consultants also said the sewer project looks eligible for SRF funding, which would likely lower borrowing costs.

Council concerns and policy options Council members raised several fiscal and equity questions: how costs would be shared between existing sewer customers and new development; whether renters or lower‑value properties would bear increased sewer rates; and whether the city should require developer contributions or a development agreement to secure private funding commitments before the city fronts major costs. Council member Jerry asked, “I’m concerned that existing customers were already raising their rates … and I’m concerned that we would be further raising their rates to support new construction that doesn't benefit them.” Staff replied that spreading some costs over more users can lower per-user rates long term, but noted developer contributions could and should be structured to reduce short‑term burdens on current customers.

Service impacts and response times Fire and police leaders briefed the council on response implications. The fire chief said the area is currently served by fire/EMS and that annexation would help the city plan future station placement to maintain quicker response times; the police chief said current call volumes were modest in that quadrant and that mutual-aid arrangements with the Scott County Sheriff’s Office would continue during buildout.

Next steps directed by council Council did not vote to annex on Monday. Instead staff was asked to return with additional analyses: (1) updated fiscal sensitivity runs that include the recent state property-tax law changes and reasonable inflation/expenditure escalators; (2) options for development-agreement terms or other legal mechanisms to secure developer contributions; and (3) alternatives for staging or financing the sewer to minimize short-term rate impacts on existing residents. Staff also described a project timeline of roughly 18 months of design and easement negotiation followed by about a year of construction if the council directs moving forward.

What to watch for: staff will return with revised fiscal sensitivity analyses, draft development-agreement approaches and draft resolutions to process voluntary annexation petitions if the council signals approval of next steps.
