ENGLEWOOD — Amid a raging statewide debate over housing availability and affordability, a small city on Denver’s southern doorstep has taken the fight to a whole new level of discord: throw the bums out. A group of citizens is targeting more than half of the seven-member Englewood City Council for ouster, citing the elected leaders’ support of “high-density housing projects negatively impacting adjacent neighborhoods,” according to recall petitions filed with the city. They also accuse the four council members — Mayor Othoniel Sierra, Joe Anderson, Chelsea Nunnenkamp and Cheryl Wink — of backing “prolific use of accessory dwelling units throughout the city.” The end result of all that increased density in this suburb of 33,000, the critics argue, is “irreparable damage to established neighborhoods” in Englewood. Englewood has been on a condo and apartment-building tear in the last couple of years.
