The city has resisted expanding the Urban Growth Area for many years, and hopes to fit both multi-family and single-family growth within the city limits. Builders counter that even City planners acknowledge that the city is "largely built out" and that the remaining land is difficult or expensive to build on. Attempts to increase density, ease restrictions on 'accessory dwelling units', or even to develop land already zoned residential, are regularly met with fierce neighborhood opposition: Padden Trails was opposed by the Samish Neighborhood Association; a dense development at the Sunnyland D.O.T. site was scaled-down; Fairhaven neighbors led the effort to prevent the development of Fairhaven Highlands, (now Chuckanut Ridge), which the City ended up purchasing for $8.2 million, preventing more than 700 new housing units; neighborhood groups pressured the City Council to go against staff recommendation to rezone Squalicum Lofts for residential development.
