THE SENATE                              S.B. NO.           S.D. 1
TWENTIETH LEGISLATURE, 2000                                     
STATE OF HAWAII                                                 

                     A  BILL  FOR  AN  ACT



 1      SECTION 1.  The legislature finds that the New Year's flood
 2 of 1988 caused many millions of dollars in damage to residential
 3 dwellings, motor vehicles, and public infrastructure in east
 4 Honolulu, severed the main roadway--Kalanianaole Highway--to and
 5 from the area, and traumatized the community.  It was only
 6 through good luck and the rapid response of county civil defense
 7 and emergency services personnel that no lives were lost to the
 8 freak weather event and the confluence of other factors that
 9 caused this flood to occur.
10      Despite the public improvements made by the county to
11 prevent a repeat of the New Year's Eve flood of 1988, no
12 permanent steps have been taken to improve the drainage of
13 Wailupe stream in Aina Haina, east Honolulu, in order to protect
14 the more than nine hundred homes that lie in the stream's flood
15 plain.  Because of inadequate flow rate and debris separation-
16 -factors aggravated by intensive urbanization in Aina Haina
17 Valley and on Hawaii Loa Ridge, Wailupe stream cannot handle the
18 large volume of runoff that would accompany another freak weather
19 event.

 1      Through the natural course of siltation and debris
 2 accumulation, the capacity of Wailupe stream will decrease until
 3 the next great flood flushes it clean.  The natural flushing of
 4 Wailupe stream would, however, expose the bridge at Kalanianaole
 5 Highway, which was not built to one hundred year flood capacity,
 6 to structural damage from floating and submerged debris.  The
 7 loss of this bridge would practically isolate east Honolulu from
 8 the rest of Oahu since the highway through Waimanalo is also
 9 subject to flooding during severe storms.  In addition, the
10 natural erosion of Wailupe stream is degrading the water quality
11 of Maunalua Bay and damaging nearshore reef formations, which
12 were damaged by decades of urban runoff, as well as abutting lots
13 along its shore embankment.
14      Consequently, the purpose of this Act is to authorize the
15 issuance of $0, in general obligation bonds for the
16 implementation of the Wailupe stream flood control project.
17      SECTION 2.  The director of finance is authorized to issue
18 general obligation bonds in the sum of $0, or so much thereof as
19 may be necessary, and the same sum, or so much thereof as may be
20 necessary, is appropriated for fiscal year 2000-2001, for the
21 Wailupe stream flood control project, to be expended as follows:
22           Plans                         $0
23           Design                        $0

                                     S.B. NO.           S.D. 1

 1           Construction                  $0
 2                TOTAL                    $0
 3      SECTION 3.  The appropriation made for the capital
 4 improvement project authorized in this Act shall not lapse at the
 5 end of the fiscal year for which the appropriation is made;
 6 provided that all moneys from the appropriation unencumbered as
 7 of June 30, 2003, shall lapse as of that date.
 8      SECTION 4.  The sum appropriated shall be expended by the
 9 department of land and natural resources for the purpose of this
10 Act; provided that the chairperson of the board of land and
11 natural resources:
12      (1)  Shall utilize county and federal funds for the Wailupe
13           stream flood control project if these funds are
14           available; and
15      (2)  May allow the department of land and natural resources
16           to assume the title of "local sponsor", should the need
17           arise, to qualify for federal funds and appropriations.
18      SECTION 5.  This Act shall take effect on July 1, 2000.
