Columbia Cascade Housing Corporation this week began onsite work toward developing a lot the City of Hood River rezoned this past spring for an affordable housing project.  Work by geotechnical engineers and surveyors will keep the Morrison Park property on 20th and Wasco closed through Wednesday.  The City Council approved the rezoning of the property from open space/public facility to high density residential to partner the housing corporation and Mid-Columbia Housing Authority on the project.  Columbia Cascade Housing Corporation executive director Joel Madsen says the work this week will provide information on what is possible on the site, adding they would like to preserve open space and natural features, create multi-modal connectivity to and from the site, and develop affordable homes.
