Re: Case No. SUP-307-08 &VAR-34-08 (Special Use Permit) Washington Elementary School
TO WHOM IT MAY CONCERN:
Please be advised there is a delivery point in place for the property being proposed for development. Pioneer
Irrigation District's main concern is that all water rights within the District be honored, and that access to irrigation
water be provided to every parcel of land.
All existing easements, right-of-ways, and other means used to honor the water rights to downstream waterusers
must be maintained and allowed to continue to exist. It is imperative that no one disrupt the delivery of water to a
downstream water user.
Any lateral, canal, drain or other means used to deliver water, along which there is a right-of-way or easement,
must have the same kept clear of all obstructions at all times. No fences, structures, or other materials are allowed
on any of the District's easements or right-of-ways AND they must be recorded on the final plat.
There are to be no pathways within Pioneer Irrigation District easements.
Any discharge or run-off into a federal drain must meet the approval of Lupe Rodriguez of the Bureau of
Reclamation. Pioneer Irrigation District does not assume any responsibility for such an approval. Her telephone
number is 383-2221, Dixie Drain — 110 foot Federal Right of Way, 55 feet from centerline of drain. There is to be
no obstructions, fences, buildings, walk paths, etc, within right of way,
Please be advised that NO change to or crossing of a District facility can take place unless a License Agreement o
Crossing Agreement between the District and the owner/developer of the property has been signed and recorded:'
Please contact the Districts Attorney, Scott L. Campbell, in writing if you need to obtain such an agreement, His
contact information is: Scott L. Campbell, Moffatt Thomas
Barrett Rock & Fields, Chtd., 101 S. Capitol Blvd., 10th Floor, Boise, Idaho 83702, phone: (208) 345-2000, fax: '
(208) 385-5384.
A License Agreement or Crossing Agreement must be written up and recorded at the expense of the Developer
and/or owner. All agreements must be reviewed by and approved by Mr. Campbell. The least expensive way to
have an agreement drawn up which meets the need of the District is by having Mr. Campbell himself draw it up,
Otherwise there will be two attorney fees for said developer and/or owner to pay. A deposit of $1000.00 must be
paid to Moffatt, Thomas to cover the attorney fees before the work can begin. Any unexpended portion of the
deposit will be refunded. Pioneer Irrigation District will recommend disapproval of the final plat approval, until the
02.20.2008 11:04 FAT 2084594491 PIONEER IRRIGATION 4 CALDWELL P Z Z002
agreement has been executed and recorded. If construction begins without the required agreement, Pioneer
Irrigation District will pursue judicial relief to stop the construction.
Plans must be received by Pioneer Irrigation District by December 15th, 2008. All construction which may
impact District facilities must be completed prior to the March 15th, 2009 deadline. The construction time-
frame which Pioneer Irrigation District allows is November let of the current year to March 15th of the
following year.
Ten percent(10%) of the PID project costs, as determined by Pioneer Irrigation District's engineer, shall be
deposited with Pioneer, in the form of a cashier's check, payable to Pioneer Irrigation District, at the time of
execution of the agreement by the Developer/Land Owner. Pioneer shall refund this deposit if the construction is
completed by March 15th, and in accordance with the terms of the agreement, otherwise the deposit shall be
forfeited to Pioneer Irrigation District.
If construction is not completed by March 15th in a manner which allows for adequate delivery of water, Pioneer will
intervene and perform whatever work is necessary to allow adequate delivery of water to patrons. This work will be
performed at the convenience and discretion of Pioneer Irrigation District. The Developer/Land Owner shall pay the
costs of this remedial work.
Any proposed development which will have downstream waterusers using gravity flow irrigation must develop their
irrigation system in a manner which will insure the downstream waterusers the ability to acquire at least as much
irrigation water for gravity flow irrigation as what they received prior to any development or construction taking place.
The gravity flow irrigation system must be totally separate from the proposed pressurized irrigation system within a
subdivision.
Please be advised, the developer shall submit detailed drawings of any proposed relocations of Pioneer Irrigation
Districts facilities, prior to preliminary plat approval. Any said relocations are subject to approval from the
Superintendent and/or the Board of Directors of Pioneer Irrigation District
Any construction that impacts Waters of the United States may require obtaining a 404 permit from the Corp of
Engineers. Greg Martinez of the Corp of Engineers can be contacted at 345-2154.
Prior to finalization of any Agreements with Pioneer Irrigation District, Pioneer Irrigation District must receive a copy
of a 404 permit that has been properly executed_ If it is determined by the Corp of Engineers that a 404 permit is
not required, Pioneer Irrigation District must be notified in writing by the Corp of Engineers that said 404 permit is
not required.
NOTE: This letter does not authorize any construction to commence until all the necessary agreements
with Pioneer Irrigation District have been executed and recorded.
If you have any questions r comments, please do not hesitate to call,
Sincerely.

Memorandum
To: Community Development
From: Gordon Law, City Engineer
Tim King, Engineering Tech II 7
Re: SUP 307-08/VAR-34-08 (Washington) Caldwell School District
Date: March 6, 2008
The Engineering Department provides the following comments on a request by Caldwell School
District for a Special Use Permit for a new elementary school and an electronic reader board sign
in an R-1 Single Family Residential zone and a building height variance from 25 feet maximum to
35 feet maximum. The site is located at 2520 Washington Ave.
Development Plans
1. Development Plans— Prior to commencing construction, plans must be prepared by the
developer's engineer and approved by the City Engineering Department which shall include the
following items:
a. Street section and alignment (including curb and gutter);
b. Sidewalk (5 foot on Linden Street and Washington Ave);
c. Sanitary sewer(per City and DEQ requirements);
d. Potable water (per City and DEQ requirements);
e. Stormwater facilities (per City Policy);
f. Street lighting (per City & Idaho Power requirements);
g. Street signage (per City and MUTCD requirements);
h. Irrigation system (per Caldwell Municipal Irrigation District requirements);
i. Vertical Datum based on NAVD 88 Datum.
Irrigation
1. Irrigation water shall be obtained from applicable Irrigation District sources. City municipal
water may be used only if the criteria specified in the Landscape Ordinance Section 10-07-
12 are met.
Page 1 of 4
2. The developer shall maintain any existing upstream drainage rights and downstream
irrigation water supply rights across the property. During the design phase of this project,
the developer or his engineer is to contact the appropriate irrigation district to help ascertain
these rights. These rights shall be shown in full, topographically, and submitted for review to
the City of Caldwell along with the developments proposed construction drawings.
Appropriate facilities to convey irrigation and drainage water across the property to take care
of any offsite needs shall be included. Existing irrigation facilities shall be relocated out side
the public right-of-way. There is to be no discharge of gravity irrigation return water into the
storm water system.
3. Supplying irrigation district shall approve the location of the delivery point.
Storm Drain
1. As noted previously, provision is to be made for the disposal of stormwater drainage in
accordance with the City Stormwater Management Manual and any updates adopted
subsequent to this application. A copy of this policy is available upon request. The engineer of
record is to provide calculations, which indicate that the assumptions in his stormwater
drainage plan comply with the requirements of the stormwater manual.
Rights-of-Way
1. Linden Street is classified as a Minor Arterial. Currently there is a public right-of-way of a forty
(40) foot one-half width right-of-way along the entire Linden Street frontage. The applicant shall
be required to dedicate an additional five (5) foot along the Linden Street frontage between the
westerly boundary and the first Linden Street approach to facilitate a right turn lane. Additional
right-of-way along the remaining Linden Street frontage is not required at this time.
2. Washington Ave is a non -classified street. Currently there is a public right-of-way of a forty (40)
foot one-half width right-of-way along the entire Linden Street frontage. The dedication of
additional right-of way will not be required at this time.
Traffic Mitigation
1. The Linden approach shall be restricted to ingress only.
The following are the required traffic related mitigation measures for the Washington Elementary
School.
1. The Washington Elementary School is expected to generate 903 vehicle trips per day.
Of the 903 trips per day, 293 are expected to be generated in the site-critical (A.M.)peak
hour. Community Planning Association of Southwest Idaho has computed the average
trip length in Canyon County to be 7.3 mi. Traffic impact mitigation should presumably
occur at both trip ends so 1/2 of the trip length should be attributed to each end. It is
estimated that trips will encounter a major intersection every half mile along any given
path. The capacity of an average fully improved intersection (assumed to be the
intersection of a collector and an arterial road) is estimated to be 5,080 vehicles/hour.
Trips generated by the Washington Elementary School Commercial will utilize: (293/hr*
Page 2 of 4
7.3 mi/trip * 0.5 trip ends * 2 intersections/mi)/5,080 veh/hr per avg intersection = 42% of
the capacity at an average intersection. This percentage represents the total capacity
utilized from each intersection (once fully improved) encountered by trips generated over
the developments half of the generated trip length.
a. The applicant shall construct 42% of the total improvements needed for an
average intersection, as defined, a nearby deficient location to be determined by
Engineering staff.
i. The applicant may, at his option, contribute monies in lieu of construction.
The basis for the obligation, however, is for construction and monetary
contributions must be made at a level commensurate with costs to
construct the same by the City and as estimated by the City.
2. Shift the exit from the bus drop-off/Faculty parking area south to align with Willow Street.
3. Shift the Parent drop-off site approach 50 feet to the east to accommodate a 220' offset
from Willow Brook (near-curb to start-of-driveway).
4. Install a 12-foot wide eastbound right turn lane at the Linden site approach 75 feet in
length plus transition.
5. Provide striping with design approval of the City Engineering department for a
continuous center turn lane on Linden and Washington.
Street
1. The applicant shall improve Linden Street to include a thirty-six and one half foot (36.5) one-
half width street section from centerline to back of curb from the east bank of the Dixie Drain to
the first Linden Street approach. The remaining Linden Street frontage shall be improved to a
twenty-four and one-half foot (24.5) one-half width. The street shall feature standard vertical
curb and gutter, 5 foot sidewalks, sub-base and asphalt paving, required storm water drainage
facilities and streetlights.
2. The applicant shall be responsible for bridge improvements at the Linden Street crossing of the
Dixie Drain necessary to meet widening requirements.
3. Any approaches on Linden Street and Washington Ave shall be required to comply with ACHD
intersection and driveway spacing and alignment standards as adopted by the City of Caldwell.
The proposed access points appear to meet these requirements.
Sanitary Sewer
1. Sewer is available from an 8" main located south of Linden Street near Washington Ave.
2. The location of sewer service, including sizing of mains, providing of easements, frontage
construction, and offsite construction are to be decided during review of improvement plans.
This development shall be required to comply with the Franklin Sewer Study.
Water
1. Water is available from a 10" line located in Linden Street and a 6" line in Washington Ave.
Page 3 of 4
2. All on site water mains will need to be looped into existing mains for fire flow and water quality
purposes. Internal main sizing and construction plan approval, will be dependent upon the
availability of fire flow.
3. The location of water service and providing of easements are to be decided during review of
improvement plans. The applicant is requesting that internal water mains be dedicated to the
city.
General
1. Construction of dedicated facilities or construction within any dedicated right-of-way is to be
performed by an appropriately licensed public works contractor and shall comply with
applicable City, State, and Federal standards.
2. Prior to commencement of construction in any dedicated right-of-way, or construction of any
improvement intended for dedication to the City or connected to a City facility, the City
Engineering staff is to be notified.
3. All traffic control for the project shall meet the requirements of the Manual on Uniform Traffic
Control Devices (M.U.T.C.D.) and the City Engineer. The contractor shall provide a traffic
control plan to the City Engineer for review prior to any construction within the right-of-way.
4. Prior to commencement of construction in any dedicated right-of-way, or construction of any
improvement intended for dedication to the City or connected to a City facility, the City
Engineering staff is to be notified. This preferably will take place in a pre-construction
conference scheduled by the engineer of record in which all appropriate personnel and utilities
are present. Appropriate City personnel are to be notified in advance of all testing (including
compaction, pressure and coliform, etc.) and given opportunity to be present during conduct of
the testing. The engineer of record or his designated representative is to witness all tests and a
log of inspection visits and testing results is to be kept by the engineer of record or his
representative.
5. Appropriate easements for drains, canals or supply ditches, transmission lines, and other
utilities shall be clearly indicated on the submitted site plan.
6. No structures shall be placed within easements.
7. The applicant shall construct pathways along all waterways in keeping with City Code 10-
07-11.
8. Any note, item or drawing element on the plats, construction drawings, engineering drawings
and/or design drawings related to the property inconsistent with City Codes, Policies and/or
Ordinances shall not be construed as approved unless it has been specifically addressed and
granted by City Council as a variance
