With Big River Community Land Trust having received a $2 million federal allocation for its plans to develop about three acres of property on Avalon Road in Hood River for affordable housing, there are some more funding sources still to be tapped and local fundraising coming as well.  Big River Executive Director Alysha Sherburne says they just submitted a grant application to Oregon Housing and Community Services, and the federal funds are a key step toward success there.  She says they are beginning to consider local contributions, looking at options for partnerships with local employers and private donors.  Sherburne says they hope to submit their land use application to local officials in a couple of weeks.  The Avalon Road property is already zoned R-2 residential.  The hope is to build around 40 housing units, with an estimated cost of $24 million.
