Nampa & Meridian Irrigation District (NMID) has finished its review of this project, which affects the District's
Kennedy Lateral and Purdam Stub Drain. The easement for the Kennedy Lateral at this location is a minimum of
fifty-five feet (55') total, twenty feet (20') left and thirty-five feet (35') right. The easement for the Purdam Stub
Drain is sixty-five feet (65') total, twenty-five feet (25') left and forty feet (40') right.
Plans indicate installation of a new box culvert that will be approximately seven feet (7') wide, five feet (5') tall
and 52 feet long; with concrete headwalls and riprap installed at each end to allow for a new road crossing named
W. Perugia Street. Please note, plans show for eight -inch (8") riprap, which should be twelve inch (12") or larger
riprap, to meet NMID's specs.
There will be crossings of a three-inch (3") pressurized irrigation main, and an eight -inch (8") potable water main
installed in a steel sleeve. Three four inch (4") and two six inch (6") conduits also will be crossing the Kennedy
Lateral at this bridge structure.
Plans indicate installation of a fence along the west easement line of the Kennedy Lateral. Storm water is shown
to be detained on site with an overflow discharging to the District's Purdam Stub Drain. There are no other
proposed encroachments of the Kennedy Lateral or Purdam Stub Drain, in these plans.
Pressurized irrigation water will be provided via a connection to the District's Umbria/ Silver oaks pump station
number 67. This will be a pump station only contract. There will be a required upgrade of the pump station to
accommodate the increase in acreage with this new development,
NMID will approve of this project; however, we would like to stress our concerns of possible future drownings in
the Kennedy Lateral, With multiple families planned to live along each side of this large irrigation facility, which
will remain an open channel with very steep sides and swift moving water. In our opinion, fencing alone is not
enough to address our concerns. This facility should be piped!
