Editor's note: This article originally contained the wrong figures for the "Hispanic or Latino (of any race)" category, and suggested that Altadena's Hispanic population had shrunk.  That is not the case, as the above tables, which have been corrected, now show.

We have not seen any new housing built, no expansion or improvements in retail stores. Then there's the large building on the NE corner of Altadena Dr. & Lincoln which is stalled, and other things too numerous to mention. No I am not surprised at all.

no space for more residents; built out. It's a GOOD thing the population hasn't gone up (much). The only way population would go up is if Altadena went "condo" or high rise crazy...which is very unlikely (other than a future MonteCedro development).

@Mister Altadena: Don't be so sure! There are state housing laws that mandate each locality have a plan to accommodate the RHNA (regional housing needs assessment) numbers generated by SCAG (www.scag.ca.gov). LA is projected to grow by 2.3 MILLION residents in the next decade. Unincorporated areas have been assigned to accommodate larger percentages of this growth than the cities. What this means is that IF a developer wants to come to Altadena and build lots of high density condos, the skids are greased. Plus, if the developer agrees to add low-income housing, they'll get an easier environmental review, higher density allowances than current zoning allows (density bonus law), reduced setbacks and parking requirements. This is all in the state's housing law (www.hcd.ca.gov). Check out LA County's General plan for unincorporated areas to see what they've signed Altadena up for...

post the link. does LA Co.Gen plan coincide or contradict w / the Altadena Comm. plan?
Steve Haussler March 10, 2011 at 05:38 AM
Ah, maybe the Patch can post the census info going back to, say, 1960? As I recall, the population hasn't changed much since then.
Steve Haussler March 10, 2011 at 05:38 AM
Correction: the number of residents has not changed much since then!

Thanks for the Altadena Community link. It looks like the plan enables population growth to 53,000. That's a 25% increase in population from where Altadena stands today. .. 25%. Additionally, these numbers were generated prior to SB375 and AB32 being passed, which gives new leverage from Sacramento for cities to build high density housing.
