Executive Summary
The purpose of this report is to assess potential impacts of the proposed subdivision "Isla del Rio" on
wildlife and habitat resources located on Eagle Island bordering the North Channel of the Boise River
within the Eagle City Code Section 9-5-8 Area of Critical Environmental Concern. The project area contains
areas classified as part of the Floodway, 100 -year Floodplain (the AE classification from FEMA), and the
500 -year floodplain (0.2% chance of flooding classification by FEMA). The proposed development will be
composed of single family homes on individual Tots built over four phases. Common areas will include
recreational facilities, ornamental ponds and natural areas. Natural areas will be enhanced through
constructed ponds, streams and other waterbodies, as well as planting of riparian vegetation. No riparian
vegetation will be removed for housing construction, although some may be altered as part of the riparian
enhancement. Buildings will have a maximum height of 35' with front setbacks of 20', rear setbacks of 25'
and minimum widths of 75'. The minimum lot size will be 10,000 sq. ft. New roadways as well as non -
motorized pathways will be constructed.
The developer's landscape and design consultant (The Land Group), the City of Eagle, Idaho Department
of Fish and Game and United States Fish and Wildlife Service (USFWS) were consulted as part of this
effort. The initial field investigation was performed on March 26th, 2015. An active bald eagle nest was
observed adjacent the property that was close enough to influence activities conducted on the property.
On Monday, June 15th, 2015, the "bald eagle working group" performed a visit to the Isla del Rio project
site to view the active bald eagle nest located on the adjacent property and discuss development
options and potential restrictions and conditions. Based on the discussion, a conceptual plan was
delivered to agency personnel for comment on June 29th, 2015. Agency personnel provided feedback on
this plan. The final development plan reflects agency input on avoidance, minimization, mitigation and
monitoring efforts, as well as enhancement and mitigation actions that were part of the original plan. A
Bald Eagle Take Permit was submitted to the USFWS on January 13th, 2016. The USFWS guideline is for a
90 -day processing time.
The 74.3 acre Isla del Rio project area is dominated by three land cover types: Pasture Grassland (57.5
%), Grassland/Herbaceous (23.8%) and Riparian Forest/Shrubland (14.6%). These three cover types
account for roughly 96% of the project area. The remaining 4% of the project area consists of the Open
Water, Wet Meadow Grassland (mesic) and Road cover types. The livestock farm has a pleasing
aesthetic, but provides little habitat value to most wildlife species. The parcel does contribute to the
agricultural character that is historic to the area. It provides open space with little human disturbance,
but the habitat value is such that few wildlife species utilize the grassland areas.
The river channel, floodplain and associated habitats are of high environmental concern. Urbanization of
these areas makes restoration or enhancement difficult or impossible. When changes occur within the
floodplain, it is important to avoid, minimize and mitigate the impacts to these areas. The Isla del Rio
development plat does call for development within the 100 -year floodplain. This will involve filling of the
floodplain but not the removal of existing riparian vegetation. Any filling of the floodplain has an effect
on flood risk and ecosystem function. However, the existing land use does not function well as part of
the river ecosystem.
The development plan calls for lowering of floodplain surfaces (excavation of the ponds on the northern
end of the property), construction of a stream channel, and planting of riparian vegetation. These
actions present opportunities to enhance floodplain and river ecosystem function in the Tong -term and
to mitigate for the effects of the development. Creating low -elevation surfaces that are designed by a
river restoration professional to promote growth of a native cottonwood forest on the edge of the
ponds in the northern end of the property would provide mitigation for impacts associated with land
use change and disturbance of the bald eagle nest and promote long-term ecosystem health.
The construction of the proposed development will increase impervious surface. The ponds will function
for stormwater in accordance with ACHD standards and requirements. The Isla del Rio development
proposes to manage the common area through its HOA. The HOA for the Isla del Rio development will
have the ability to levy fines and put liens on properties.
The final development plan seeks to avoid and minimize disturbance to nesting eagles over the short
and long term and provides long-term mitigation for changes made within the floodplain. The goal is to
create phased approach for construction activities on the property that eventually allows for residential
development to occur within the 660' buffer (but outside the 330' buffer) of the nest site through
making all practicable efforts to avoid and minimize disruption of eagles at the nest location.
Lowering of floodplain surfaces, planting of native riparian vegetation, proper common area
management, control of invasive weeds, successful design and implementation of the waterways and
development of vegetation screening for the eagle nest and minimization of human penetration into
riparian habitat areas will determine the Tong -term effect of the proposed development on the Area of
Critical Environmental Concern.
Introduction
Purpose
The purpose of this report is to assess potential impacts of the proposed subdivision "Isla del Rio" on
wildlife and habitat resources located on Eagle Island bordering the North Channel of the Boise River
within the Eagle City Code Section 9-5-8 Area of Critical Environmental Concern. This information is
intended to fulfill the requirements of the City of Eagle Comprehensive Plan.
Project Location and Environmental Setting
The project area is a 74.3 -acre parcel located on Eagle Island on the Boise River within the City of Eagle,
Idaho (Figure 1). The Boise River splits into what is commonly referred to as the North Channel and the
South Channel of the Boise River as it flows around the island. The property is currently a livestock farm
(Figure 2). The property has a series of canals, ditches and drains for irrigation purposes. Current land use
on Eagle Island includes gravel extraction, agriculture, ranching and residential development. As the
metropolitan area continues to grow, there are plans to expand residential development on Eagle Island.
The project is located east of Hwy 55 (Eagle Road) between an existing development and former gravel
extraction ponds.

The property borders the Boise River and contains floodplain surfaces that are or have been connected to
the river's hydrology. These are Areas of Critical Environmental Concern and contain a suite of native and
game species. Part of the property lies within the floodway and 100 -year floodplain mapped by FEMA.
The floodplain areas contain wetlands that are subject to regulation of the U.S. Army Corps of Engineers.
An active bald eagle nest has been observed adjacent to the property.
Project Description
The proposed development, Isla del Rio, will be composed of single family homes on individual Tots (Figure
3) built over four phases. Common areas will include recreational facilities, ornamental ponds and natural
areas. Natural areas will be enhanced through constructed ponds, streams and other waterbodies, as well
as planting of riparian vegetation. No riparian vegetation will be removed for housing construction,
although some may be altered as part of the riparian enhancement (Figures 3 and 4). Buildings will have
a maximum height of 35' with front setbacks of 20', rear setbacks of 25' and minimum widths of 75'. The
minimum lot size will be 10,000 sq. ft. New roadways as well as cycling and pedestrian pathways will be
constructed as well.

Existing Information
Prior to the field investigation, Ecosystem Sciences consulted with the developer's landscape and design
consultant (The Land Group), the City of Eagle, Idaho Department of Fish and Game (IDFG) and United
States Fish and Wildlife Service (USFWS) to gather necessary information. An information request was
made to the Idaho Fish and Wildlife Information System (IFWIS), which provided GIS shapefiles containing
plant, fish and wildlife species occurrence data within a 1 -mile buffer of the project area, including special
status species. In addition to the IFWIS data, we acquired 2013 aerial imagery (2013 NAIP), floodplain
mapping (FEMA), Lidar and relative surface modeling data (RSM) (Richardson and Guilinger 2015). Project
development plans and renderings were acquired from The Land Group in order to understand the
planned project actions.
Initial Field Investigation
The initial field investigation was performed on March 26th, 2015 by scientists Derek Risso and Tamsen
Binggeli of Ecosystem Sciences. Field maps with aerial imagery, IFWIS data locations and the project
area boundary were prepared. Using GPS points, digital photographs and notations on field maps,
observations were made of landforms, land cover types, hydrology, and plant and animal species. A
route was planned that visited all land cover types, both the north channel, sloughs, side channels and
locations of historic special status species occurrences.
Bald Eagle Nest and Bald Eagle Working Group Activities
An active bald eagle nest was observed adjacent the property that was close enough to influence actives
conducted on the property. Following discussions with city, state and federal personnel, a "bald eagle
working group" was formed to address the issue and make recommendations for development actions
to avoid, minimize and mitigate for impacts on the eagle nest site. The group was composed of Matt
Stuber, USFWS, Charlie Baun, ECS, Rick Ward, IDFG, and Derek Risso, Ecosystem Sciences.
On Monday, June 15th, 2015, the "bald eagle working group" performed a visit to the Isla del Rio project
site to view the active bald eagle nest located on the adjacent property and discuss development
options and potential restrictions and conditions. The nest does not occur on the parcel proposed for
development; therefore, the development has no control over the land on which the nest resides.
However, based on its proximity, activities on the development parcel may have an effect on the eagles
and therefore efforts to minimize and avoid disturbance were discussed. Based on the discussion, a
conceptual plan was delivered to agency personnel for comment on June 29th, 2015. Agency personnel
provided feedback on this plan. Following subsequent meetings and consultation, a final plan was
created to develop the property that contains a number of measures to avoid, minimize and mitigate for
potential impacts on the bald eagle nesting site. The final development plan reflects these changes as
well as enhancement and mitigation actions that were part of the original plan. The final plan includes a
monitoring plan in addition to numerous modifications to the original development plan. A Bald Eagle
Take Permit was submitted to the USFWS on January 13th, 2016. The permit application is pending.
Land Cover Mapping
Utilizing photographs, GPS points and notes from the field, remotely sensed imagery (including the
infrared band of the 2013 NAIP imagery), Lidar, and the RSM, habitat (land cover) within the project
area was mapped in ESRI's ArcMAP 10.3 software. Special status species occurrences were located and
shapefiles created.

Environmental Features
Hydrology, Landform and Floodplain Mapping
The project area lies on Eagle Island, a low-lying floodplain area consisting primarily of alluvial landforms.
Prior to the construction of Luck Peak Dam, the area experienced frequent flooding events which have
historically shaped the Eagle Island landscape. Today, these events are Tess frequent and severe due to
the managed releases from Luck Peak Dam. Eagle Island is a highly modified landscape, with gravel
extraction, levee and berm building, agriculture, ranching, and urbanization as major drivers of landscape
change.
The project area contains little topographic relief, but some areas are more prone to flooding than others.
The project area contains areas classified as part of the Floodway, 100 -year Floodplain (the AE
classification from FEMA), and the 500 -year floodplain (0.2% chance of flooding classification by FEMA).
(Figure 5 and Figure 6). The FEMA AE classification includes the Floodway and areas outside of the
Floodway that are within the 100 -year floodplain. The 500 -year floodplain is labeled as having a 0.2%
chance of flooding (1 in 500). The majority of the property is within the 100 -year floodplain, making the
property a low-lying area. Please note that this mapping is not the revised FEMA floodplain mapping as
that data is not yet available for this area.

The project area contains current and historic side channels, sloughs, and high-flow channels. Many of the
areas that were historically connected (hydrologically) to the Boise River have been physically
disconnected by rip -rap and levees. These areas are best illustrated through the examination of the
relative surface model of the area (Figures 7 and 8) (Richardson and Guilinger 2015). The RSM portrays
land surface elevations in relation to the water surface elevations along the Boise River at a given
discharge (in this case 7000 cfs). The RSM does not represent actual inundation areas and is only shown
for visualization and planning purposes. The model is a representation of low versus high areas on the
floodplain based on a theoretical water surface generated in GIS using LiDAR data and has not been
calibrated to any measured or modeled water surface elevations.
The importance of low-lying areas for flood control, habitat, and river function should not be
underestimated. Any effort to preserve, reconnect, or enhance existing low-lying areas of the Boise River
floodplain is important to the function and value of the Boise River ecosystem. With such a Targe
proportion of the project area in the 100 -year floodplain, measures will need to be taken to ensure that
flood risk is not increased due to development.
These low-lying areas have a better connection to river hydrology, including groundwater and hyporheic
zone. These areas also contain an abundance of species. For example, a beaver dam on the northeast side
channel or slough increases the amount of aquatic habitat and changes the local hydrology for the benfit
of several species. The riparian vegetation provides important habitat for a large suite of species.

Vegetation
Land Cover
The 74.3 acre Isla del Rio project area is dominated by three land cover types: Pasture Grassland (57.5 %),
Grassland/Herbaceous (23.8%) and Riparian Forest/Shrubland (14.6%). These three cover types account
for roughly 96% of the project area (Figure 9, Table 1). The remaining 4% of the project area consists of
the Open Water, Wet Meadow Grassland (mesic) and Road cover types.

Land Cover Type Descriptions
Grassland/Herbaceous (xeric): This cover type is a mix of grasses and forbs similar to those found in
wet meadows but containing more facultative species such as bluegrass (Poo spp.), mint (Mentha spp.),
mullein (Verbascum spp.), salisfy (Tragopogon spp.), and an array of other grasses and herbs (many of
which were not able to be identified due to field visit timing). Shrubs such as blackberry (Rubus spp.),
rose (Rosa woodsi) and false indigo (Amorpha fruticosa) are found interspersed within this cover type.
Although this cover type was green at the time of the field visit, we anticipate that these areas will dry
out without irrigation later in the year during the hot and dry season.
Grassland/Herbaceous (xeric) understory in the northwest corner of the property. Riparian forest visible in
background and Pine Slough water on the left of the frame. This area is in a degraded condition.
Open Water: Water occurs throughout the project area in the form of ditches, sloughs and side channels.
For this project, irrigation ditches are inclusions in the Wet Meadow Grassland and Pasture/ Grassland
cover types. An active side channel is located along the eastern edge of the project area. In the northwest,
numerous irrigation ditches converge to create a wetland slough, called Pine Slough.

Active side channel located in northeastern portion of the project area. This area was partially mapped a�p
Water and partially mapped as Riparian Forest/Shrubland. The area on the far side of the open water is an island
between the side channel and the North Channel of the Boise River.
Pasture Grassland: This cover type is dominated by irrigated mixed grasses for use by livestock and horses.
This cover type includes small ditches and canals that deliver water around the project area. Larger canals
are mapped as the Wet Meadow Grassland cover type. Within the project area, this cover type consists

Riparian Forest/Shrubland: This cover type is dominated by black cottonwood (Populus balsamifera ssp.
trichocarpa), box elder (Acer negundo), willow (Salixsp.), and silver maple (Acer saccharinum). Occasional
black locust (Robinia pseudoacacia), cherry (Prunus spp.) and a variety of other trees occur occasionally
as well. The understory is primarily made up of false indigo (Amorpha fruticosa), blackberry (Rubus spp.),
rose (Rosa woodsi), golden current (Ribes aureum) and other riparian species. The project area does not
represent a native riaprain system, but rather a mix of native and non-native species commonly found
along the Boise River. The Grassland/Herbaceous (xeric) cover type is often found beneath the canopy,
while the Wet Meadow Grassland (mesic) and Open Water occur to a lesser extent. Note that some of the
side channel habitat mapped as Riparian Forest/ Shrubland has open water below the canopy.
Riparian Forest patch along the side channel in the northeast corner of the project area. Cottonwoods dominate
the canopy in this section. The bald eagle nest is visible on the right side of the frame, outside the project area.
The bald eagle nest is discussed in detail in following sections.
Road: The cover type consists of one paved road in the southwest corner of the project area that leads
into the agricultural compound.
Wet Meadow Grassland (mesic): This cover type persists in areas that are seasonally flooded/irrigated or
those directly adjacent to or within water bodies. Common species associated with this cover type are
rush (Juncus spp.), bulrush (Scirpus spp.), cattail (Typha latifolia) and orchard grass (Dactylis glomerata).
Small ditches and waterways are frequent inclusions. Based on the vegetation species and near infrared
signatures, these areas stay saturated for longer periods than the drier grasslands.
Near the north boundary of the project area, irrigation return water (shown flowing toward Pine Slough) and
associated wet meadow species, such as mixed grasses, rush (Juncus spp.), and cattail (Typha latifolia), are
included in the Wet Meadow Grassland cover type. A berm that disconnects Pine Slough from the Boise River is
visible on the right.
Plant Species Known to Occur in the Area
A list of plant species known to occur in the Eagle area was compiled prior to the field investigation from
IDFG and Ecosystem Sciences files. It is included in Appendix A.
Special Status Plant Species
Aase's onion (Allium aaseae) is the only special
status plant whose potential habitat was
identified within a 1 -mile buffer of the project
area, according to the Idaho Fish and Wildlife
Information System (IFWIS). Aase's onion (Allium
aaseae) is a small perennial plant in the Lily
family (Liliaceae). It typically blooms in early
spring and is found in elevations from 2,700 to
3,700 feet (Mancuso 1995). Aase's onion is
endemic to southwest Idaho and has been
documented in the lower foothills from Boise to
Emmett, and in two locations in Weiser
Aase's onion (Allium aaseae) (photo by Scott Earle).
(Mancuso 1995). It grows in generally open, sparsely vegetated, southerly slopes with sandy substrate
and is usually associated with bitterbrush/sagebrush communities (Mancuso 1995). Our land cover
mapping and field investigations did not find habitat associated with this species within the project area.
Observed Plant Species from Field Survey
The field investigation was performed in late March. Therefore, many of the plants were either dormant
or were just beginning their seasonal growth. This investigation was reconnaissance level and the species
listed (Table 2) should not be viewed as an inventory, but rather as species or taxa common or likely to
occur based on the available information and professional judgment of the scientists.

Black Cottonwood Dominated Riparian Forest
Historically, the riparian community along the Boise River was dominated by a black cottonwood riparian
forest (Kaltenecker et al. 1994). Much of this area has been converted to urban, agricultural and non-
native species dominated landscapes (USACE 1995). These cottonwood forests are important to many
bird and wildlife species, especially nesting and wintering bald eagle populations. The riparian forests are
also important to fish and other aquatic organisms, as they stabilize stream banks, provide habitat, and
reduce solar Toads that increase aquatic temperatures. These habitat areas are critical to a wide array of
species and ecosystem processes.
False Indigo
False indigo (Amorpha fructicosa) is an invasive perennial shrub species of the Legume family that was
found throughout the Riparian Forest/Shrubland and Grassland/Herbaceous cover types, sometimes
occurring in thick stands along the Boise River. It grows from 3 to 12 feet tall and has firm woody branches
that create an open canopy with most of the foliage in the upper third of the plant (NRCS 2003). Its flowers
are tubular in appearance and bloom from late -spring to mid -summer (NRCS 2003). False indigo easily
out -competes most native woody shrub species and it can create such a tight canopy that it precludes
growth of other plants (NRCS 2003). False indigo was a common species in the understory of the Riparian
Forest/Shrubland cover type.
Fish and Wildlife
IFWIS Historically Observed Species
Data on fish and wildlife observations were obtained from the Idaho Fish and Wildlife Information System
(IFWIS) for sightings or documentation of species within a 1 -mile buffer of the project area. Appendix B
provides a list of all historically observed fish and wildlife species. Table 3 shows special status species
documented within a 1 -mile buffer of the project area. No special status species have been documented
to occur within the project area, only within the 1 -mile buffer. Species information and habitat
preferences were reviewed prior to the field visit. Special attention was paid to sightings near the project
area (Figure 10).

Two special status species, the bald eagle (Haliaeetus leucocephalus) and the double -crested cormorant
(Phalacrocorax auritus), were observed within and near the project area during the field surveys. Bald
eagles were observed flying within the project area and occupying a large nest just outside the east
boundary of the project area on both occasions. Several double -crested cormorants were observed flying
near the project area during the March field survey. During the June 15th field visit, a double -crested
cormorant was observed flying within the project area.
Double -crested cormorants
In a recent study by the Ada County Highway District, double -crested cormorants were observed nesting
in the Great blue heron rookeries located south of the project area (ACHD 2013). Black cottonwood trees
and adjacent wetland and open water are essential habitat components for survival. During the project
survey, double -crested cormorants were seen flying overhead and into the project area. They likely access
side channels and river channel for feeding. Double -crested cormorants are impacted by habitat
alteration, fragmentation, and human disturbance (ACHD 2013).
Bald Eagles
Migratory Bird Treaty Act of 1918
The Migratory Bird Treaty Act of 1918 prohibits the "take", such as hunting, wounding or possessing, of
migratory birds, nests, feathers or eggs. This Act applies to all of the birds observed during the field survey.
The bald eagle has additional protections under the Bald and Golden Eagle Protection Act which include
incidental takes associated with disturbance. For this reason, the Eagle Take Permit process was initiated.
The Bald and Golden Eagle Protection Act
The Bald and Golden Eagle Protection Act (Eagle Act) protects bald eagles from a variety of human
activities that could harm them directly or potentially interfere with their ability to forage, nest, roost,
breed, or raise young (16 U.S.C. 668-668c). The U.S. Fish and Wildlife Service (USFWS 2007) developed
guidelines to provide landowners and planners general recommendations for land management practices
to uphold provisions of the Eagle Act. Though not legally binding, the U.S. Fish and Wildlife Service
strongly encourages adherence to these guidelines.
Human activities, including noise levels and visual proximity, can affect nesting bald eagles (Table 6).
Disturbance may lead to inadequate construction of the nest, prolonged absence from the nest, or
abandonment of the nest, among other impacts (USFWS 2007). However, not all bald eagles react to
human activity in the same way. Human activities can affect foraging and roosting bald eagles by
preventing eagles from feeding and taking shelter, which reduces chances of survival and productivity
(USFWS 2007).
Eagles are unlikely to be disturbed by routine (ongoing) use of facilities already in proximity of their nest
or foraging areas (USFWS 2007). The height of the nest may also ameliorate effects of human activities.
However, occasional or permanent changes may disturb bald eagles. In these cases the U.S. Fish and
Wildlife Service recommends, 1) keeping distance from the activity and the nest (distance buffers), 2)
maintaining forested (or natural) areas between activities and the nest (landscape buffers), and 3)
avoiding certain activities during the breeding season (USFWS 2007). In general eagles are more prone to
disturbance when an activity occurs in full view (USFWS 2007). For expansion of development, a distance
of 660 feet and maintenance of natural buffer is recommended if the activity is visible from the nest, such
as the nest located on Eagle Island, with construction occurring outside of the breeding season (USFWS
2007) 15 recommended. With certain measures to avoid, minimize and mitigate for eagle disturbance, a
permit may be issued to perform activities up to 330' from the nest (Figure 11). In addition, general
protection of surrounding trees that could serve as alternate nest sites and supporting habitat is
recommended (USFWS 2007).

Changes to Development Plan Based on Presence of Eagle Nest
Based on the presence of an active bald eagle nest adjacent to the project site location, several changes
to the original development plan (see original plan below — Figure 12) were made. The changes seek to
avoid and minimize disturbance over the short and long term and to provide long-term mitigation for
changes made within the floodplain. The goal of these changes is to create a development context that
will allow for construction activities and eventually a residential development to occur within the 660'
buffer (but outside the 330' buffer) through making all practicable efforts to avoid and minimize disruption
of eagles at the nest location. Further, enhancements to the riverine-riparian system are proposed with
the goal of improving long-term habitat conditions along the Boise River.

Figure 12. Original development plat. The original plan included enhancement of the common areas, but additional
measures were added following the eagle nest discovery.
Iambs Rerbc
The final plan concept includes the following measures and changes to the original plat to achieve this
goal (see the revised plan view drawings and eagle nest exhibit sheet below, Figures 13 and 14):
• Decreasing the size of Pond #2, moving street locations and reducing the number of buildable lots
adjacent to the nest (overall parcel count is not reduced) to create a common area that extends
330' from the current nest location. Throughout the area, lot sizes have been reduced and the
as
common area increased between buildable lots and the river.
• Building a 10'42' berm and planting cottonwood trees that will be 20' tall in the first year (which
will grow to 50' at maturity) to create a visual and audial barrier between the eagle nest and the
development. The cottonwoods will be under -planted with shrub vegetation to enhance
screening. Figure 14 illustrates the sight -line projections from the nest to the proposed
development.
• Creating a water feature and improved riparian habitat between the berm and the eagle nest to
create an aquatic barrier and provide increased habitat value immediately around the nest site.
The water feature will be fed by an existing irrigation canal and create a connection with the
existing side -channel (or slough).
• Elimination of the paved pathway to not enter the 330' buffer from the nest. There will be no
pathways within the 330' buffer. All paved pathways have been removed from the plan. All
proposed pathways are of a natural surface.
• Enhancing a Targe common area adjacent to the river outside of the 330' buffer that will be managed
as part of the HOA and provide long-term improvement in riparian habitat. This will involve a new
water course and connections to the river and existing side channels (sloughs). Ponds and riparian
enhancement will occur in the northern and northwestern part of the site. These areas are outside
the 660' buffer, but will provide long-term habitat enhancement. The originally planned
greenbelt -type pathway in the riparian area has been re-routed to follow the edge of the property
lines and will be a natural surface, pedestrian only pathway. All existing riparian vegetation will
remain and new riparian vegetation will be planted. This will provide a long-term benefit to eagles
and the myriad of other wildlife species who utilize the Boise River and its associated riparian
zone.
• Grading will occur outside the breeding season to avoid disturbance. Areas within the 330' buffer
would be planted immediately following grading (and prior to nesting season) to provide the most
vegetation growth and establishment possible in an effort to minimize the impact on nesting
eagles. Under the phased development approach, this area will have years to develop prior to
construction activities within the 660'buffer.
• A phased approach (four phases) to construction will be implemented, with the first phase occurring
at the west end of the property. The initial phase of home construction will be approximately 0.4
-0.5 miles west of the eagle nest. The eagles will therefore have time to adjust to slowly increasing
noise and human activity. The phasing will also aid in vegetation screening development. The
subsequent phases that include construction activities within the 660' buffer will be dependent
on the development of the vegetation screen. The timeline for construction within this area is
estimated to be years into the future, therefore allowing for substantial vegetation development.
• The following monitoring approach will be performed during the breeding season only (January
until fledging). It is unlikely that the egg will be laid in January, but the courtship and nest building
period is a very sensitive period for the eagles and the conditions at this time of the year will be
important for judging nest disturbance. A qualified field scientist will visit the site on a monthly
basis. The following activities associated with each visit will be performed:
• Observations of the nest activity will be made. The stage of nest development will
be determined (courtship and nest building, egg laying, incubation and hatching,
nestlings present, fledging).
• Digital photos and notes on vegetation development will be made. The digital
photos will be taken at GPS points along the 660' buffer from the nest and the
330' buffer from the nest and will face the nest.
• An interview with the Williamson family (local residents who currently own and
operate the existing farm) will be made and their observations recorded.
• Upon returning to the office, a short report that includes photos, observations,
and interview results will be filed on the Ecosystem Sciences servers.
• At the end of each breeding season the height of the vegetation will be measured
and recorded.
• If the eagles abandon the nest and construct a nest within 660' of any construction activities, the
USFWS will be immediately notified and any construction activities within 660' of the new nest
will be halted until consultation with the USFWS can occur.
• If there is nest abandonment, permission from USFWS and the City of Eagle to convert the eagle
nest screening common area into buildable lots may occur.

Information on Nesting Eagles in the Area
The existing information regarding the breeding season bald eagle habitat use in the Boise River system
is scarce. Information presented is courtesy of personal communication with local state, federal and
private professionals and the IDFG IFWIS species occurrence database. The best available literature on
bald eagles within the basin is over 20 years old and is focused on wintering Bald Eagles (Kaltenecker et
aI.1994). Additional winter monitoring of bald eagles has continued (Kaltenecker 2000), with the emphasis
on the Barber Pools and Dead Dog Creek (in the Upper Boise watershed) Communal Roost sites.
Nesting Sites
There are five known recent nesting sites in the Lower Boise Basin (Figure 15), including the nest site in
close proximity to the Isla del Rio development site (Eagle Island Nest Site). The furthest away is in the
Fort Boise Wildlife Management Area at the confluence with the Snake River (35 miles — see Table 7).
Eagles are known to nest in the Upper Boise Basin (Kaltenecker et a1.1994) where there is much Tess
development pressure and habitat modification. These nest sites apparently represent an increase over
the nesting in the basin 20 years ago, as Kaltenecker et al. (1994) describe nesting eagles as only occurring
in the Upper Boise Basin. The key habitat element associated with nest sites (and roost sites) are the large
trees, specifically the black cottonwood (Populus tricocarpa) found along the Boise River.
Table 7. Distance of known recent bald eagle nest sites in the Lower Boise River system.
Nest Site Distance from Project Area
Barber Pools 13.8 miles
HWY 16 Bridge 6.8 miles
Lake Lowell 17-20 miles (large area)
Fort Boise 35 Miles
Roost Areas
Kaltenecker et al. (1994) includes a literature review which was combined with winter observations in the
upper portion of the Lower Boise area to identify several roost sites. The most important of which is the
Barber Pools area. Lake Lowell is identified as well, but few studies have examined the lower reaches of
the Lower Boise, and no recent investigations exist.
Foraging Areas
Bald Eagles are known to forage on fish from the Boise River throughout its length, as well as on its
associated gravel ponds and reservoirs (Kaltenecker et a1.1994). The fish populations in the Boise River
have increased over the past 20 years, partially due to increased winter flows. Wild rainbow trout and
brown trout populations have increased in the upper reaches over the last 20 years, including a 17 -fold
increase from 1994 to 2010. Wild trout predominate even though monthly stocking of hatchery trout has
occurred over this period. Rainbow trout populations have increased in proportion to brown trout in
recent years. Mountain whitefish populations far exceed those of wild brown or rainbow trout (Ecosystem
Sciences Foundation 2015 and Butts 2010). The waterfowl associated with the river, its wetlands and
gravels ponds also provide likely prey sources, as do carrion and other opportunistic food sources. The
winter bald eagle surveys of the Barber Pool roost site concluded that the eagles at this roost site made
daily trips to the Boise River to forage.
Other Important Habitat Areas
Kaltenecker et al. (1994) identifies 16 important habitat areas for wintering bald eagles in the Lower Boise
River Basin. These areas basically encompass the Boise River from Lucky Peak Dam to Garden City (well
above the project site). Likely this is attributed to the importance of the Barber Pools wintering site at the
time of the investigation.
As to nesting bald eagles like the pair that occupied the nest site adjacent to the proposed project, the
river corridor and its associated riparian vegetation can be considered important habitat areas. A healthy
riparian system with mature trees and a productive aquatic ecosystem that supports abundant fish
provide key habitat elements that the eagles require.

Discussion of Environmental Impacts
Impacts on Areas Not of Critical Environmental Concern
The livestock farm has a pleasing aesthetic, but provides little habitat value to most wildlife species. The
parcel does contribute to the agricultural character that is historic to the area. It provides open space with
little human disturbance, but the habitat value is such that few wildlife species utilize the grassland areas.
The economic forces in the area make a working horse farm unlikely to survive in the Tong -term. The
impact of the Isla del Rio development on the Targe portion of the project area not associated with the
riverine-riparian area is predominantly an increase in noise, impermeable surface, and human presence.
The vegetation, plant life, and habitat value may increase for many species that tolerate the human
environment post -development, with the planting of trees and shrubs and other landscaping elements.
The additional open water provided by the ponds would create waterfowl habitat that does not exist. The
value of these open water areas will be significantly increased by creating land surface elevations close to
the water surface elevation near the edges that would be capable of supporting wetland and riparian
vegetation. Because much of the project area is low-lying, it is conceivable that it could be enhanced to
create a better connection to the hydrology of the Boise River, but this would likely entail the conversion
of the area to a preserve or public area and require heavy investment.
Impacts on the Area of Critical Environmental Concern
Impacts on Riparian Vegetation and the Floodplain Connection
The river channel, floodplain and associated habitats are of high environmental concern. Urbanization of
these areas makes restoration or enhancement difficult or impossible. When changes occur within the
floodplain, it is important to avoid, minimize and mitigate the impacts to these areas. The Isla del Rio
development plat does call for development within the 100 -year floodplain (Figure 6). This will involve
filling of the floodplain but not the removal of existing riparian vegetation. Any filling of the floodplain has
an effect on flood risk and ecosystem function. However, the existing land use does not function well as
part of the river ecosystem. Therefore, concerns are centered on increased flood risk and the Toss of future
restoration opportunity.
The lowering of floodplain surfaces (excavation of the ponds on the northern end of the property), the
construction of a stream channel, and the planting of riparian vegetation present an opportunity to
enhance floodplain and river system function in the long-term and to mitigate for the effects of the
development. The plan for this enhancement is in its early stages of development; the details of the final
plan will be paramount to the value of these areas. The removal of any existing small berms on the
northern end of the property (Figure 7) and/or allowing a connection of any of the constructed waterways
with the existing river hydrology and benefit river function and long-term habitat value. The lowering of
any surfaces near the river so that they are inundated or saturated on a relatively frequent basis (e.g.
inundated by 3500-6000 cfs discharge at Glenwood Bridge) would benefit the river ecosystem and
promote native riparian vegetation development. Creating low -elevation surfaces that are designed by a
river restoration professional to promote growth of a native cottonwood forest on the edge of the ponds
in the northern end of the property would provide mitigation for impacts associated with land use change
and disturbance of the bald eagle nest and promote Tong -term ecosystem health.
Beaver currently have constructed a dam on the side channel in the northeastern portion of the property,
which provide habitat and attract birds, fish and other wildlife species. We recommend that the dam be
left in place and beaver managed by protecting the largest trees with wire or other protective measures.
Planting of the pond edges (both within the development and in the northern section by the river) with
native species and creating "no -mow zones" would promote riparian development and provide a natural
and aesthetically pleasing environment.
Storm Water Management and Water Quality
The construction of the proposed development will increase impervious surface. The ponds will function
for storm water in accordance with ACHD standards and requirements. To the extent feasible, the
stormwater management plan should be designed with the appropriate free -board and meet green storm
water infrastructure guidelines (http://www.partnersforcleanwater.org/outreach/green-stormwater-
infrastructure/). The design, construction and management of the common area and ponds represent an
important opportunity for mitigation for the project's impacts.
Management of Common Areas
The management of common areas can be a challenge for developments such as Isla del Rio. Homeowners
have been known to cut trees and remove desirable vegetation to increase the view from their property
or for other reasons. Some of the lots include existing riparian vegetation (see lot lines in Figure 6). Often
cities have little or no ability to enforce the common area rules or prevent actions by homeowners that
would impact the quality of these areas. Common areas frequently are managed by HOAs, cities or other
organizations. The Isla del Rio development proposes to manage the common area through its HOA. The
HOA for the Isla del Rio development will have the ability to levy fines and put liens on properties. This
allows for an enforcement mechanism. The HOA rules should protect native riparian vegetation and
impose stiff penalties to those who break such rules.
The creation of a weed management program would benefit the riparian area and provide mitigation for
the impact associated with the development. False indigo is an invasive shrub that has spread
throughout the Boise River floodplain. Seasonal or yearly weed management to reduce the cover of this
plant would benefit the ecosystem. One-time treatment is not a successful weed management plan for
false indigo; it requires persistence and a Tong -term commitment.
Greenbelt and Development Pathways
Providing walkways, bicycle pathways and connectivity of our living and recreation environments has
many benefits. However, penetration of human pathways into natural areas can disturb wildlife and
reduce habitat value. Paved and high traffic areas have greater impacts than natural surfaces and
pedestrian -only pathways. The development plan call for natural surface pathways in the riparian area
and paved pathways that enter the development and provide connectivity to future pathways to the
south.
The developers of the proposed project have shown an interest in working with IDFG, US Fish and Wildlife
Service and Parks and Recreation staff and other interested parties to devise a plan that provides for
multiple uses and benefits.
Effects on Eagles and Other Riparian Wildlife Species
Nesting bald eagles are an important natural resource whose numbers have increased in the Boise River
system over recent decades. The eagles can be viewed as an umbrella species that protect habitat for
numerous other species. The Isla del Rio developers have demonstrated an interest in protecting the eagle
nest and the riparian habitat on which the eagles and other species depend. The reduction in the number
of developed lots, vegetation screening, aquatic waterway development, and lowering of floodplain
surfaces all provide short and long term benefits for the Boise River ecosystem. However, the eagles
constructed a nest in the present location for a reason. It not located near human disturbance areas and
is situated close to foraging and perch habitats. The development presents a possible disturbance to these
conditions. Nests are temporary; it is unlikely that this nest site will persist in perpetuity. The more
important question over the long term is: what is the long term habitat quality of the Boise River
ecosystem, specifically the aquatic and associated riparian ecosystem? The proposed development plan
will result in more aquatic habitat, more riparian vegetation, and lower floodplain surfaces. The success
of these mitigation and enhancement measures will determine the long-term effect on eagle and other
wildlife habitat.
Conclusions and Recommendations
Much of the property within the project area consists of an agricultural landscape of low habitat value.
Much of the proposed project is within the 100 -year floodplain. The low-lying areas and those close to
the river and its associated sloughs and side channels with native riparian vegetation are of high
importance (located in the northern part of the project area). Minimization of impacts to these areas and
enhancement of existing low-lying areas will result in a development scenario that maintains ecosystem
function while accommodating the need for appropriate human uses. Lowering of floodplain surfaces,
planting of native riparian vegetation, proper common area management, control of invasive weeds,
successful design and implementation of the waterways and development of vegetation screening for the
eagle nest and minimization of human penetration into riparian habitat areas will determine the long-
term effect of the proposed development on the Area of Critical Environmental Concern.
