( 1 ) of the total 30000 square feet in our current leasehold , we are consolidating our operations into 20000 square feet during 2004 and are currently offering the remaining 10000 square feet for re-lease or sub-lease .
we have seven additional area offices in the united states through which our tower leasing and services businesses are operated on a local basis .
these offices are located in ontario , california ; marietta , georgia ; crest hill , illinois ; worcester , massachusetts ; new hudson , michigan ; mount pleasant , south carolina ; and kent , washington .
in addition , we maintain smaller field offices within each of the areas at locations as needed from time to time .
our interests in individual communications sites are comprised of a variety of fee and leasehold interests in land and/or buildings ( rooftops ) .
of the approximately 15000 towers comprising our portfolio , approximately 16% ( 16 % ) are located on parcels of land that we own and approximately 84% ( 84 % ) are either located on parcels of land that have leasehold interests created by long-term lease agreements , private easements and easements , licenses or rights-of-way granted by government entities , or are sites that we manage for third parties .
in rural areas , a wireless communications site typically consists of a 10000 square foot tract , which supports towers , equipment shelters and guy wires to stabilize the structure , whereas a broadcast tower site typically consists of a tract of land of up to twenty-acres .
less than 2500 square feet are required for a monopole or self-supporting tower structure of the kind typically used in metropolitan areas for wireless communication tower sites .
land leases generally have an initial term of five years with three or four additional automatic renewal periods of five years , for a total of twenty to twenty-five years .
pursuant to our credit facilities , our lenders have liens on , among other things , all towers , leasehold interests , tenant leases and contracts relating to the management of towers for others .
we believe that our owned and leased facilities are suitable and adequate to meet our anticipated needs .
