If you would like to converge the two sites, I'd suggest submitting norwalkcity.com to it's proper DMOZ catagory and have it listed that way.
Then I'd simply upload a simple redirect page at your cpinteract.com site that states the site has moved, give brief information regarding the Cerritos college and a link to the new location for the site at norwalkcity.com, such as "http://norwalkcity.com/cpinteract/" or however you like.
Then simply leave the cpinteract.com site alone as the redirect. This way, anybody who searches out the Cerritos College lands at the cpinteract.com site and they are simply lead to it's new location at norwalkcity.com
Hope that helps,
