The Johnston City Council voted 3-2 on Monday to approve a conservation-themed residential development on land recently annexed into the city.

Hubbell Realty Co. proposed the Crosshaven development earlier this year on 277 acres near Northwest 100th Street and Northwest 78th Avenue. The development will be limited to about two homes per acre and feature open spaces, trails, prairie grasses and wildflowers, and water-management techniques intended to minimize the project’s environmental impact.

Some residents of the area initially opposed the annexation and development, claiming it would reduce property values and increase traffic.

In two previous 3-2 votes, the City Council approved rezoning the property to allow for the development. The city’s planning and zoning commission also approved the rezoning.

Hubbell has similar developments in Grimes, Waukee and Carlisle.
