Chapter 11 - Special Areas and Sites
11.1
Background and Vision
"Special Areas and Sites" are defined as areas, sites or structures of historical,
archaeological, architectural, ecological, or scenic significance. Special areas or
sites should be analyzed according to their defined function. Whenever possible,
these sites should be preserved and conserved as open spaces or for educational
and cultural centers. Development of Special Areas or Sites should take place in a
manner that reflects hannony with their natural environment and recognized
qualities which render them distinctly unique.
11.2
Recognized Special Areas and Sites
Boise River Floodplain
The Boise River Floodplain is designated as a special area due to its ecological
and scenic significance. The area comprises the two channels of the Boise River
and intervening and immediately adjacent areas as generally depicted on the
Comprehensive Plan Land Use Map.

ZONING ORDINANCE PROVISIONS WHICH ARE OF SPECIAL CONCERN REGARDING
THIS PROPOSAL: None
DISCUSSION:
.
The applicant has requested a variance from the requirement to construct the residential
finished floor two-feet (2') above the base flood elevation, and from the requirement to
construct roadways and manholes Y2-foot (0.5') above the base flood elevation. This is based
in part on the existing conditions of the surrounding area and the development that has
occurred within recent years. With the recent adoption of the February 19,2003, Flood
Insurance Rate Maps (FIRM), the Base Flood Elevation (BFE) of this particular area was
raised from 2559 to 2562. (NOTE: Due to a change in the datum used for the map study, 3.1
feet should be added to the BFE as noted on the pre-2003 maps to correspond to today's BFE).
This in essence places several existing buildings in the immediate vicinity of this site
(Albertsons, Eagle Pavilion) 3-feet below the current BFE. If this subject site were required to
be built 2-feet above the BFE, this in effect would place the floor of the buildings on this site
approximately 5-feet above the floor of the surrounding buildings. A "mounding" effect,
compared to the surrounding elevations) would occur as a result of the elevation of this site. It
should be noted that the requested variance from the City's standards and is not a variance from
the Federal Emergency Management Agency (FEMA) regulations, which require all residential
structures to be placed at the BFE or higher. Yet, with the revised BFE, the elevation of this site
will be required to be raised from its current elevation, although measures can be taken during
construction of the homes to reduce the effects of the increase and still remain within the FEMA
regulations (see ECC Section 10-1-8-5 (A) (3».
.
Eagle City Code Section 10-1-8-5 (F) (1) allows development with the TDA (Transitional
Development Area) and CEDA (Community Entry Development Area) to place fill material
within the site, which is prohibited within other areas located within the floodplain. The intent
of this exemption is to encourage development in the downtown area of the City, where the
only practical way for a site to develop was to allow fill to be placed on sites located within the
floodplain. However, the disadvantage of allowing fill material in any flood hazard area is the
loss of water storage during a flooding event.
This subject site is located in Flood Insurance Rate Map number l6001CO153 within the AH
zone, which is defined as an area within the floodplain subject to ponding with a potential rise
in floodwater from I to 3-feet. Both the Flood Plain Administrator and the City Engineer
concur that to elevate this site with fill to comply with the BFE (as shown on the current FIRM
maps) may create a greater problem with the surrounding buildings that were constructed
under the prior BFE, since water storage capability would be lost and, this site may cause an
obstruction to any water flows that may occur. In addition, there is also a practical difficulty in
constructing roadways to align with the existing streets adjacent to this site.
.
As a point of information, the residents of this subdivision would be required to carry flood
insurance on the dwellings due to the location of the site within the floodplain. There would be
no advantage gained by raising the homes 2-feet above the BFE (as required in Eagle City Code)
since FEMA only requires homes to be at the BFE.

STAFF RECOMMENDATION PROVIDED WITIllN THE STAFF REPORT:
If the City Council approves the variance, then based upon the information provided to staff to
date, staff recommends the site specific conditions of approval as outlined within the staff report.
PUBLIC HEARING OF THE COMMISSION:
A. A public hearing on the application was held before the Planning and Zoning Commission on August
18, 2003, at which time testimony was taken and the public hearing was closed. The Commission
made their recommendation at that time.
B. Oral testimony in opposition to the applicant's request was presented before the Planning and Zoning
Commission by no one.
C. Oral testimony in favor of this proposal was presented to the Planning and Zoning Commission by one
(I) individual (not including the applicant/representative) who described the methodology in
calculating homeowner's association reserves used for the maintenance of common areas and private
roadways, and that this developer has been highly responsive to resident's concerns in similar
developments.
COMMISSION DECISION:
The Commission voted 3 to 1 (Crook against, Deckers absent) to recommended approval ofV-2-
03 for a variance ITom the requirement to construct the residential finished floors two-feet (2')
above the base flood elevation, and from the requirement to construct roadways and manholes Y2-
foot (0.5') above the base flood elevation, with the following staff recommended site specific
conditions and standard conditions of approval with underlined text to be added by the
Commission:
SITE SPECIFIC CONDITIONS OF APPROVAL:
1. The applicant shall comply with all requirements ofFPDP-4-03.
2. All mechanical units located with the garages of the single-family dwellings shall be Flood- proofed.
3. No finished floor elevation shall be constructed below the Base Flood Elevation.
4. NFP A regulations require that all enclosures below the BFE in A zones be designed to allow for the
automatic equalization of hydrostatic forces during a flood event. The applicant shall comply with
Section 60.3 (C)(5) of the NFIP regulations which states:
"All new construction and substantial improvements, fully enclosed areas below the lowest floor that
are usable solely for parking of vehicles, building access, or storage in an area other than a basement
and which are subject to flooding shall be designed to automatically equalize hydrostatic flood forces
on exterior walls by allowing the entry and exit of floodwater. Designs for meeting this requirement
must either be certified by a registered professional engineer or architect or meet or exceed the
following minimum criteria: minimum of two (2) openings having a total net area of not less than one
square inch for every square foot of enclosed area subject to flooding shall be provided. The bottom of
Page 7 of9
K\Planning Dept\Eagle Applications\V ARIANCE\2003\V-O2-03 pzfdoc
all openings shall be no higher than one foot (1 ~ above grade. Openings may be equipped with
screens, louvers, or other coverings or devices provided that they permit the automatic entry and exit
offloodwaters. "
5. This variance shall not be considered as establishing a binding precedent to grant other variances.
6. The applicant shall place a note on the final plat generally stating that the subdivision is located within
the AH zone of the floodplain. with a potential for ponding of water from one-foot (1') to 3-feet (3') in
depth. and as such is subject to requirements of Eagle City Code Title 10 (Flood Control) and FEMA
regulations regarding insurance.
CONCLUSIONS OF LAW:
1. The application for this item was received by the City of Eagle on July 23,2003.
2. Notice of Public Hearing on the application for the Eagle Planning and Zoning Commission was
published in accordance for requirements of Title 67, Chapter 65, Idaho Code and the Eagle City
ordinances on July 29, 2003. Notice of this public hearing was mailed to property owners within
three-hundred feet (300-feet) of the subject property in accordance with the requirements of Title 67,
Chapter 65, Idaho Code and Eagle City Code on July 24, 2003. Requests for agencies' reviews were
transmitted on July 24,2003, in accordance with the requirements of the Eagle City Code.
3. The Commission reviewed the particular facts and circumstances of the proposed variance (V-2-03) in
tenns of Eagle City Code Section 10-1-10 (C) (5): (required findings for approval of a variance) and
has concluded that:
a. A showing of good and sufficient cause exists since a variance would encourage
development in the downtown area of the City, and allow a practical way for the site to
develop by not having to place additional fill in the floodplain, which would cause the loss
of water storage during a flooding event;
b. While the failure to grant the variances would not result in exceptional hardship to the
applicant, a hardship may be encumbered upon property abutting this site due to the
placing of fill material to raise the site above the Base Flood Elevation which may increase
the depth of flooding on adjacent parcels and create an obstacle to the efficient draining of
the area during a flood event; and
c. The granting of a variance will not result in increased flood heights, additional threats to
public safety, extraordinary public expense, create nuisances, cause fraud on or
victimization of the public, or conflict with existing local laws or ordinances since the
opposite of these situations may occur should the site be required to raise above the BFE.
Increased flood heights could occur since the filling of this site would remove flood
storage capacity from the area and thereby threatening damage to property and public
safety and creating a nuisance to other properties. The variance would not be in conflict
with existing laws or ordinances since Eagle City Code prohibits the location of fill
material in areas within the floodplain (other than the DDA, IDA and CEDA).
4. The dissenting opinion of the Commission felt that residential uses in the floodplain should be afforded
Page 8 of 9
K:\Planning DeptlEagle ApplicationsW ARlANCE\2003\V-O2-03 pzf.doc
the extra protection (beyond those required by FEMA) that the requirement of the two-foot (2')
minimum finish floor elevation above the BFE provides, and by approving this variance, that
protection is diminished.
