The Initial Study/Mitigated Negative Declaration is now available for a proposed residential condominium project at 235 South Arroyo Drive.  The Arroyo Village Residential Condominium Project (project) would construct a 41-unit residential condominium development on an approximately 1.16-acre site located at 235 South Arroyo Drive.  The proposed project requires approval of a Tentative Tract Map, Precise Plan of Design, Setback Variance, and Grading/Building Permits.  An IS/MND has determined that the proposed project may have a significant effect on the environment, but by implementing the identified mitigation measures, the project's impacts could be reduced to less than significant levels.  Information related to the IS/MND can be found below:

The Planning Division works to help create and enhance a vibrant city by respecting the City’s diverse and distinct neighborhoods, promoting a prosperous economy, and providing a forum for community engagement.

  • Helping applicants make property improvements, build new homes, or open new businesses;
  • Facilitating public outreach and notification for large new development;
