The county is joining a number of local cities in challenging housing growth projections contained in the latest Regional Housing Needs Assessment plan prepared by the Southern California Association of Governments.
The RHNA figures are intended to guide cities and counties in developing housing needs, and are subject to enforcement by the state.
The county challenge is against a projected growth of 57,502 dwelling units in the unincorporated areas over the next eight years.
County officials challenge growth projections and methodology used in creating the number, which has already been reduced by some 5,000 units under earlier county protests.
In the unincorporated part of the Arroyo Verdugo region, which includes La Crescenta, a growth of 369 units is suggested, 154 of them very low and low income. For the city of Glendale, SCAG is forecasting a growth of 3,104 units in eight years.
The RHNA numbers are not predictions, but are what SCAG considers a fair share allocation of housing needs. City and county housing plans are required to provide the opportunity for growth in their zoning and land use plans.
This year's survey requires that areas with low vacancy factors provide even more housing opportunities in all income categories. Cities must provide these opportunities through zoning and land use policies.
Among the six Southern California counties which work with SCAG, LA has the largest mandated growth, at 287,667 units.
Los Angeles is listed for about 40 percent of the county growth, at 113,698. The Arroyo Verdugo Region, which includes Glendale, La Cañada and Burbank, is listed for 7,459 units in eight years.
Deadline for appeals is March 15, with a final allocation to be released in June.
