§302A-1607  Construction cost component impact fee; determining the amount of the fee.  (a)  The construction cost component impact fees shall be calculated using the following factors:

     (1)  For new school construction, the cost per student for each school type (elementary, middle or intermediate, and high school) shall be based on the ten-year average construction of a new school facility using the Honolulu assessment district in 2006 as the base.  Costs for construction completed earlier than 2006 shall be escalated to 2006 using the engineering news-record construction cost index;

     (2)  For expansion of existing school facilities, the cost per student for each school type (elementary, middle or intermediate, and high school) is based on the ten-year average construction of whatever components are required to expand the school using the Honolulu assessment district in 2006 as the base;

     (3)  The cost per student in other assessment districts shall be the cost per student in the Honolulu assessment district multiplied by the appropriate cost factor in subsection (d).  At least every three years, the authority shall update the cost per student based on the construction of a new permanent school facility, and present the written analysis to the board for review; and

     (4)  Student generation rates, as defined in section 302A-1602.

     (b)  The student generation rate for each school type (elementary, middle or intermediate, and high school) shall be multiplied by the cost per student for each school type (elementary, middle or intermediate, and high school) to determine the cost per dwelling unit in the development.

     (c)  The construction cost component impact fee shall be based on recent public school construction costs.  The 1997 to 2007 period school construction costs per student, adjusted for both the year 2007 and for the Honolulu assessment district, are as follows:

     (1)  Elementary schools:  $35,357 per student;

     (2)  Middle and intermediate schools:  $36,097 per student; and

     (3)  High schools:  $64,780 per student.

The costs per student for other assessment districts shall be determined by multiplying the Honolulu assessment district costs per student by the applicable cost factor in subsection (d).  These costs per student shall be updated at least every three years, pursuant to the provisions in section 302A-1612.

     (d)  The State shall be divided into the following twenty-six geographically limited cost districts, and the cost factors listed for each cost district shall be applied to the calculation of school construction costs per unit pursuant to subsection (c):

     Ewa                  Leeward/Central           1.00

     Hana                 Maui                      1.35

     Molokai              Molokai                   1.30

     Lanai                Lanai                     1.35

     Lihue                Kauai                     1.15

     Koloa                Kauai                     1.20

     Kawaihau             Kauai                     1.20

     Waimea               Kauai                     1.25

     Hanalei              Kauai                     1.25

     (e)  At least every three years, and concurrent with any update of the costs per student, the authority shall update the revenue credits and present the written analysis to the board for review.  The calculation of revenue credits shall be reviewed and calculated recognizing that the impact fee shall be set at one hundred per cent of the fair market value of the land and ten per cent of the total school construction cost.

     (f)  The construction cost component of the impact fees per dwelling unit shall be ten per cent of the amounts calculated according to the following formula:

     Cost per dwelling unit from subsection (b) minus any amount by which the revenue credit per dwelling unit from subsection (e) exceeds ninety per cent of the per unit construction cost.

     (g)  The amount of the fee shall be adjusted from the date it was determined to the date it is paid using the engineering news-record construction cost index, or an equivalent index if that index is discontinued.

     (h)  Any new residential development shall be required to obtain a written agreement executed between the owner or developer of the property and the authority, prior to the issuance of a building permit, under which the owner or developer has agreed to a time specified for payment of its construction cost component impact fee.
