1.0 INTRODUCTION
1.1 Purpose of the Report
This biological technical report summarizes the results of biological investigation conducted for
the 4K J\partrncnts project and related off<;ite improvements, and describes existing conditions of
biological resources, including on-site vegetation, jurisdictional aquatic resources, flora, wildlife,
potential for special-status species to occur on-site and wildlife movement. The biological
significance of these resources and potential for impacl from development of the project are
evaluated, and rneasures arc recommended to avoid, minimize, or mitigate potential impacts
consistent with the Cal!fiJrnia t:11viro111nental Quality Act (CEQA) and applicable local, slate and
federal rules and regulations, including the City of Carlsbad 1-labi(at Management Plan (HMP).
1.2 Project Location
Encinas Creek Apartments LLC proposes to develop the 4K J\partrncnts project, a 153-unit
apartment project including a l,200 foot section of College Boulevard (College Boulevard North
Segment) on a 7.52 acre property generally located south and easl of the present intersection or
College l1oulevard and Cannon Road in the northeast quadram of the City of Carlsbad. See
Figure I; l.ocation Afap. The prqject is located in the northeastern section of the City of
Carlsbad, approximately 1.5 miles inland from the Pacific Ocean and lying north and east of El
Camino Real.
The 4K Apartments are proposed on the residentially-zoned property, located at 33.153909
degrees North latitude and I 17 .283652 degrees West longitude on the lJ.S. Geological Survey
7.5-minute series topographic San Luis Rey quadrangle map. Sec the aerial photograph of the
property on Figure 2: Vicinity Map. The prope1ty is identified as APN 168-050-60-00, and is
owned by Encinas Creek Apartments LLC. The property is somewhat isolated from existing
urban improvements and contains no frontage on a public street. Therefore the project applicant
also includes construction of the College Boulevard North Segment and approximately 450 linear
feet ofa collector ::.trcet (Street 'A') in order to provide vehicular and utility access to the property.
The property affected by the project, including access roads, to\als 13.88 acres.
The property is within the Carlsbad llydrologic Unit as identified by the California Regional
Water Quality Control Board. The Agua Hedionda hydrologic sub-arc drains the site westerly to
Agua Hedionda Lagoon. The property slopes from a high point (elev. 160) at the southeastern
corner to a low point (elev. 90 ft.) at the northwestern corner of the site. Surrounding land uses
vary; including the Rancho Carlsbad community located west ofthe project, the Carlsbild Unified
Sage Creek ! ligh School located north of the site, and vacant land planned for future residential
and infrastructure development to the cast and south.
The property is located within the limits of the Carlsbad Habitat Management Plan, which
regulates open space preserve patterns through the protection ofhardline preserve area \Vithin the
City. Within the context of this HMP, a hardline for the 4K J\parttncnts property was approved by
the l!SFWS, CDFW and the City of Carlsbad in 2006. ·1 his hardlinl." demarcates the limits of
development from the limits of habitat preserve.

1.3 Project Description
The project applicant proposes the development of 153 multifamily apartment units in five, three-
story residential buildings, plus a single-story leasing/activity building, with associated parking,
utilities, and landscaping. Surface and single car garage parking spaces arc provided in close
proximity to all of the units.
Access to the site is proposed via two entrance points on future Street 'A', which stems off of the
future College Boulevard temporary stub. The internal vehicular system is comprised of three
driveways that encircle the buildings and provide access to the apartments units. The project will
provide affordable housing, in accordance with an Affordable Housing Agreement and the City of
Carlsbad Density Bonus requirements.
Vehicular access to the site will he through construction of a portion of College Boulevard to
provide connection from the existing intersection of College l:3oulevard and Cannon Road south
to a proposed collector street (Street 'A'), to the 4K Apartments development site. College
£3oulevard is designed to Carlsbad Major Arterial standards (4-lane, median, 102-foot ROW), and
Street 'A' is designed as a collector street (2-lane, 60-foot ROW). Both streets will be designed
with temporarily cul-de-sacs, as they are planned to eventually continue on to access properties
further south and east.
1.4 Physical Characteristics of the Site
The land area proposed for the 4K Apartments and access to the site are located in northeastern
Carlsbad, within the Agua Hcdionda Creek Watershed of the Carlsbad Hydrologic Unit of the
San Diego region. The Agua Hedionda Creek and its tributaries drain about 9 sqLLare miles from
the foothills of Vista, into and through the central portion of Carlsbad, where it ultimately
discharges into Agua Hedionda Lagoon and the Pacific Ocean at Carlsbad State Beach.
The subject apartment property is characterized as relatively flat or gently sloping (from southeast
to northwest), undeveloped vacant land, much of which contains fallow agricultural fields, and a
portion of which contains native habitat. Little 1::ncinas Creek, a tributary to Calavera Creek and
Agua Hedionda Creek, traverses the area from east to west just north of the 4K Apartments
property and crosses through the area of the College Boulevard North extension. The College
Boulevard North Extension travels from the pre:;,ent intersection of College Boulevard and
Cannon Road, in a southeast direction, to accommodate a future connection at I::! Camino Real.
approximately one mile south. This extension crosses through the eastern end of Rancho
Carlsbad Mobile Home Park and through a short section of native hillsides and agricultural fields.
At the approximately 1,200 foot mark southerly Crom the College and Cannon intersection, Street
'A' is proposed to extend easterly off of a temporary College Boulevard cul-dc-.sac to provide
access easterly onto Street 'A' and into the 4K Apartments property.
The subject property contains a number of single-lane dirt agricultural and utility service and
access roads which are heavily utili:ted by both off-road automobile.sand, more recently, by
sporting trail bicycle enthusiasts. These automobile routes and recreational uses have also
impacted portions of the property.

2.0 METHODS
Prior to the field investigations conducted by Planning Systems, a review ofthc existing biological
resources within the vicinity of the 4K Apartments and College Boulevard North Segment property
was conducted using the Caliromia Natural Diversity Data 8ase (CNIJIJB) (CDFW 2015), ljSFWS
occurrence data ( USFWS 2015), and California Native Plant Society (CNPS) (CNPS 2015). The
Carlsbad HMP was also reviewed with respect to species covered by this plan and the location of
hardlines. A previous biological report for the property, Biological Resources Report and Impact
Analysis for the Holly Spring, Pro;ect by RECON, dnted rcbruary 8, 2003 and the Merkel &
Associates, College Boulevard Reach A Biological Resources Report, dated March 19, 201 0
were also reviewed. The purpose or the review of this infom1ation was to determine if sensitive
habitats, or special-status plan( and wildlife species were known to inlw.bit the combined project area,
and what resulting com,traints these inhabitants might have on the property.
2.1 Biological Reconnaissance Survey
Biological surveys were conducted during the period from July 14 through July 28, 2016, as
shown on Tahle 1. The field surveys covered the entire area shown on Figure 2, plus a 100-foot
mapping buftCr around tl1e perimeter. Surveys included vegetation mapping, a wildlife survey
and focused surveys for coastal Cali!Ornia gnateatcher (Polioptila ca!{fc;rnica califc1rnica).

The survey visits included the following elements:
• \!lapping of habitat types:
• A directed search for special-status plant and animal species with potential to occur
within the surveyed area;
• A general inventory of plant and wildlife species;
• Eva I uation of suitability of habitat for specia!-statw, resources identified during the
literature search;
• Preliminary identification of areas that may be considered wetland or non-wetland waters
of the U.S., as defined by the U.S. Army Corps of Engineers (USACE) and the COFW;
• Notes on other pertinent features or conditions of the site.
Vegetation communities \vere mapped by the biologists in the field directly onto a 200-scale ( 1
inch = 200 feet) false-color digital orthographic map of the property (Google Earth 2016). A
Trimble R2 GNSS handhc!d sub-meter receiver \Vas used to verify locations as necessary. Tl1cse
boundaries and locations were digititcd using TcrraFlex and AuloCAO software. Vegetation
community classifications used in this report follow Holland ( 1986) and Oberbauer et al. (2008).
A list of plant species observed on the property is provided in Appendix A.
2.2 Coastal California Gnatcatcher
Wildlife species detected during the field surveys were recorded. Binoculars (]Qx42 power) were
used to aid in the identification of observed wildlife. and any special-status species observed or
detected were mapped. In addition to species actually detected. expected wildlife use of the site
was determined by known habitat preferences of local species and knowledge of their relative
distributions in the area. Presence/absence surveys for the California Gnalcatcher (Po!iopli/a
cal//Ornica cal/fi.1rnica) were conducted. All other species detected during SLLrveys were recorded.
A list of wildlife species observed on the property is presented in Appendix B.
2.3 Jurisdictional Delineation
A Wl:tlandjurisdictional detennination was conducted ror the College Boulevard North Segment.
The jurisdictional delineation analysb in the Final Environmental Impact Report (E!R) for the
Calavera Hills Master Plan Phase II. Bridge and Thoroughfare District No. 4, & Detention Basin.
2001 (SCH #99111082) was reviewed for designated drainages, vegetation and wetlands.
Further, the College Boulevard-Reach A Biological Resources Report, by Merkel & Associates,
Inc., March !9, 2010 was also reviewed for the similar information. Dming the fieldwork for the
jurisdictional delineation, the data were recorded using a global positioning system (GPS) llnit
with submeter accuracy. The results of the jurisdictional delineation are presented in a separate
report titled Jurisdictional Determination Report for the College Boulevard Reach A North
Segment. A copy of this report is presented in Appendix C to this report.

The scope of the pro_jectjurisdictional delineation assessment was within a very limited area in
which College Boulevard North Segment is proposed to be constructed. The construction limits
traverse existing Little Encinas Creek, which consists ofa relatively narrow_ well-defined
drainage, traveling cast to west, with relatively steep banks and no surface water. The roadway
plans show the Little Fncinas Creek to be placed into a culvert under the roadway. No other
_jurisdictioncil areas were identifkd within the arec1 to be impacted by the development.
2.4 Soils
The project development site has been mapped b} the Soil Conservation Service (SCS). Their
information indicates that the soils on the propert~ consist of;
• Ronsall sandy loam (Bl [2), which i~ moderately well drained, shallow to moderately
deep sandy loams, generally used for range and watershed;
• Cieneba-fallbrook rocky sandy loam (CnE2), which is excessively drained, very shallow
to shallow coarse sandy loams, generally used for rnngc and watershed; and
• J luerhuero loarn (! !rlJ and llrl::2), which is moderately well drained loams with clay
subsoil; generally used for range, truck crops. tomatoes and flowers.
·1 he broad Encinas Creek valley across which the short section of College Boulevard will travel
consists largely of;
• Tujunga sand (Tu13), which is very deep, excessively drained sands formed on
f1oodplains and alluvial fan~. generally used for range with small areas used for
avocados, flowers and truck crops.

3.1.1.1 Diegan coastal sage scrub (Code 32510)
Diegan coastal sage scrub (DCSS) is a relatively low-growing, soft-woody subshrub community
that is approximately three to four feet in height and most active in winter and early springtime.
\1any of the taxa within this community are facultative drought deciduous. Diegan coastal sage
~crub typically occurs below 1,000 feet and is frequently dominated by coastal s<1gebrush
(Artemisia cal{fornica).
DCSS is found on I .21 acres on the northwest facing slope of the 4K Apartments property and
0.31 acres of a small steeper slope within the College/Street 'A' extension property. Onsite,
coastal sagebrush b dominant, and Lcmonadeberry (Rhus integri/iJ!ia) is a primary sub-dominant.
Other sub-dominants on the property include flat-topped buckwheat (Frior;onum,ff.1.w:iculatum
var. _fl1scicula1wn), and California adolphia (Ado!phia californica).
3.1. l.2 Southern Mixed Chaparral (Code 37120)
Southern mixed chaparral is ,1 vegetation community that has greater than 70% ground cover
attributable to evergreen sclerophyllous shrubs and drought-deciduous malacophylous subshrubs
with no single species contributing greater than 50% of the cover. Plants in this community
include laurel sumac (l'vfalosma laurina), lemonadebcrry (Rims inlegr[fhlia). coast live oak
(Quercus agrifi_Jlia). chaparral bushmallow (Ma!acothamnusji:t.w.:iculatus), black sage (Salvia
mdlifera), coast monkeyflower (:ifimulus m1ran1iacus), toyon ([le!erom!!les arhutzj<J/ia) and
some other sage scrub associates.
Onsite, Southern mixed chaparral is found on the extreme north end of the property, on 0.52 acres
of the eastern part of the north-facing natural slope.
3. I. U Non-native Grassland (Code 42200)
Non-native grassland is dominated by non-native grasses, mostly originating from the
Mediterranean region, and growing on areas witl1 a history of agriculture. Although this
community is made up of non-native vegetation, the community is considered of value to wildlife
as generally high-quality foraging territory.
On~ite. approximately 1.04 acres of the project area is covered with non-native grassland. The
onsite non-native grasslands contain the presence of indicators Avena, Brom us. l::rcx:lium, and
Bras~ica. It is dominated hy one or several non-nati\C. invasive broadleafspecies .. where
historical disturbance and nearby seed sources have resulted in the cstabl ishment of extensive and
persistently dominant non-native broadleafspecies. These species include Brome grass (Bromus
sp.), tumbleweed (Salwla tragus). short-pod mustard (Hirs/eldia incana), tocalote (Centaurea
me/itensis), doveweed (Croton setiger). and others.
3.1.2 Non-Sensitivl' Habitats
3.1.2.l Eucalvptiis Woodland (Code 79100)
Eucalyptus woodland is found in two small, isolated patches totaling 0.10 acres in total.
Eucalyptus woodland onsitc contains little or no shrubby understoiy. Few native species arc
present within these small forests. On::.ite. the [:ucalyp!us woodland species includes red river
gum (Hucalyptus camalduiensis) with an understory primarily ofleaflitter.

Disturbed habitat refers to areas characterized by predominantly nonnative species introduced and
established by human activity. to the degree that they arc no longer recognized as naturaliLed or
native \"egetation. These areas arc not typically anificia/!y irrigated, but receive water from
precipitation or natural runoff This designation includes highly compacted ground devoid of
vegetation and the monotypic pockets of native plants surrounded by nonnative species.
Onsite, approximately 0.42 acres of the site is considered Oisturbed land. The disturbed habitat
consists primarily of the dirt utility service road traversing the apartment property. and the
embanked slope supporting existing Cannon Road at the existing intersection. Non-native
species in the disturbed habitat include crystalline iccplant (Afesembryanthemwn crysta!linum).
red-stem fi!aree (Erodium cicutarium), and other pioneer species. Native species are scattered
within the disturbed habitat in very low numbers including fascicled tarweed (Deinandra
jOsdculata) and white-margin sandmat (Euphorhia albomarginata).
3 .1 .2 .3 Auricullurn! Land (Code Jg:; I 0)
Agricultural lands consist of land cover which is presently or has recently been under agricultural
production. Onsite, agricultural lands cover the majority (4.96 acres) of the 4K Apartments site
and 4.61 acres of the College/Street 'A' extension. Although row crops are planted and harvested
regularly, Non-native grassland vegetation and native recruits have begun to re-establish in
some areas. Non-natives present include Short-pod mustard. (Hir.w.:hfe!dia incana) common
sow-thistle (_,\'onclms oleraceus ), Brazilian pepper tree (Sch in us terehinthi/iJ/ius). and non-native
gra~scs.

maintained under the 1--lMP preserve design. The results of the literature review indicate !lie
potential occurrence of 12 fl\tlP Covered Species in the vicinity of the project. Based on the
results of historical biological surveys in the area, two ofthesc plant species (Thread-leaved
brodiaea and Nutall's scrub oak) and three wildlife species (Coastal California gnatcatcher,
Southern California rufous-crowned span·ow and the Orange-throated whiptail) were determined
to have a moderate or higher potential of occurring within the impacted property due to the
presence of suitable habitat and historical observance in the area. Of these, only two isolated
Nutall's scrub oaks were identified during the 2016 site surveys. Both of these oaks arc not
located within an area proposed for any development, but rather are within the JOO-foot mapping
buffer around the perimeter of1!1e development, amongst the Southern mixed chaparral habitat on
the north side of the apartment site. No other HMP covered species was observed on !lie
property.

within the I IMP area. and that substantiul loss of these populations or their habitat within the
HM!' area could jeopardize the continued existence or recovery of that species. The results of the
literature review indicate the potential occurrence of 14 Narrow Endemic Species in this area.
I !owever, based on the results of the biological surveys, none of these species were observed to
occur within tile specific project impact area.
3.2.3 Spedal-Status Plants Which :\fa~, Occur Onsitc
The results of the literature review conducted prio:· to the field surven indicated the potential
occurrence on the site of six (6) plant _c,pecies and iive (5) wildlife species listed as Threatened or
Endangered at the Federal and/or State level (hereafter referred to as listed species). rhese are
listed among the I IMP and l\'arrow Endemics identified in the fol lowing two tables. A map of
previously identified occurrences of sensitive species in the area is provided on F1);11re 4.
Special-status plant species considered in this report are those that are; (a) listed by federal and/or
state agencies, propo~ed for listing as threatened or endangered. or listed as candidate species; or
(b) listed in the Carlsbad IJMP. The potential for special-status plant species to occur on site was
evaluated based on previous documentation, the elevation, soils, vegetation communities, and
level of disturbance of the site. as well as their ~talus and distribution in the vicinity of the project.
Based on the results of the biological surveys, none of these special-status species were observed
within the impact area during the survey, and only one (I) plant species, t,vo specimens of
Nutall's scruh oak (Q11erc11s dumom), ,verc observed within the 100-foot perimeter mapping
buffer. These oaks will not be impacted by implementation of the project. Several small
specimens of Spiny Rush (Juncu,· acut/1.\) were observed in the sandy. dry, Liule Encinas Creek
stream bed, however this species is not considered Special Statu~. It is however, Jepson listed and
also recorded on the California Native Plant Society Rare Plant list.

State.
The jurisdictional delineation deterrn i ned that a total of 0. 12 acres of jurisdictional non-wetland
waters ofthc U.S. and State exist within the College l:foulcvard extension to Cannon Road and
will thus be directly impacted by com,truction of College Roulevard. These jurisdictional waters
are associated with the installation of a culvert under the road½ay to accommodate drainage
within existing Little Encinas Creek. an ephemeral stream flowing from east to west, north of !he
apartment development site. No other jurisdictional aquatic resources exist within the project
area. ·1 his determination is attached as Appendix C to this report.
3.5 Wildlife Movement Corridors
The City of Carlsbad HMP is an approved NCCP subarea plan. addressing potential impacts to native
and sensitive species and habitats while providing mitigation options in the form of conserved lands
that satisfy the habitat-protection requirements of the Federal ESA and California ESA. The HMP
provides for open space connectivity that is conducive to animal movement, allowing animals to
access significant areas for foraging. hunting and water source:,. In addition, these protected habitat
corridors allow the dispersal of individuals away from high human population areas and facilitate the
exchange of genetic traits between populations. Thus the ! IMP preserve is a network of large blocks of
open spaces with interconnecting linkage:, which ~erve to benefit the animals which live and utilize
these areas.
Focus Planning Areas consisting of large blocks of habitat (Core Areas) and connections between
these areas (Linkages) are i<lentified throughout the City in the Carlsbad HMP based on the exi~ting
distribution of vegetation communitie~ and sensitive species. This program has resulted in the
adoption ol'hardline areas. which arc designated as permanent open space. ·1ake ofthe habitat on the

Direct Impacts. Although there is no record of direct observation of California
gnatcatchcrs on the project site, this species is known to occupy open coastal sage scrub habitat
that is dominated by coastal sagebrush, similar to that observed on the property. /\.s such. thi~
species could he directly impacted hy loss of suitable habitat for roraging or nesting. The
proposed development will respect the adopted hard line for the property. Since the project is in
compliance with the requirements of the I livlP, and no gnatcatchers have been observed to inhabit
the property, it is determined that no significant impacts to this wildlife species will occur.
Precautionary avoidance measures, in accordance with the criteria identified in the Carlsbad H:v!P,

The property supports native habitats. which also provides potential nesting and foraging habitat
for a variety of other songbirds and raptors in the area. Although no active nests ½ere identi(ied
during the 2016 5urveys, there i~ a significant potential for birds to nest within the project area. In
the event that construction work occurs during the breeding sea~on (February 15 through August
3 l ), nesting raptors and other nesting birds could be directly impacted hy vegetation clearing
activitie~. These impacts ½ill have an adverse effect on sensitive species and will thus require
mitigation. l labitat impacts will be mitigated according to ratios, as required by the Carhbad
1 IMP and will offset any potential impacts to special-status species.
Since no special status plants or wildlife have been documented on the site, no direct impact to
sensitive plant species is anticipated. The proposed project will not result in a direct impact on
any federal. state or local-listed special status species, or any of the twenty-~ix (26) HMP
sensitive and narrow endemic plant species that could occur onsite. This conclusion is drawn
hecau~e the plant and wildlife surveys did not conclude that any candidate, sensitive or special
~tatus species would be impacted hy the project.
Indirect Impacts. No indirect impacts to the Nuttall's scrub oak trees located offsite to
the north will result from the project due to the fact that an open space buffer in excess of60-feet
is provided between the proposed apartment project and the oab.
b. Will the project have a mbstantial adverse effect on any riparian habitat or
.\em;itive naturnl communi(r ident{fied in lorn/ or regional plans, policies, and regulations or
by CDFW or USFWS?
Direct Impacts. The proposed project IAiould result in permanent impacts to both
~ensitive and non-sensitive habitats. The tables below quantif)' the impacts that Mrnld result
from implementation of the 4K Apartments project and the College Boulevard North Segmcm

Indirect Impacts. Several indirect impacts will result from implementation oflhe
pn~ject, unle.~s precautions are taken to minimize or mitigate those indirect impacts.
Minimization and mitigation of these indirect irnpacb are recommended as follow::.:
Fire Suppression. A fire suppression buffer between the proposed 4K Apartments and the
habitat in the hardline preserve are accommodated for public safety and fire protection purpose:,.
·1 his fire suppression buffer will be located on the development side of the hardline and as a result
provide additional protection between the develop:ncnt and the protected habitat. Thus the
project wi 11 not result in significilnt indirect impacts from fire buffer fuel management on the
habitat.
l::ro:::.ion Control. ln order to avoid indirect impacts to downstream properties and Little 1:::ncinas
Creek from degradation due to exces:::. :,edimentation, the project developer will be required to
prepare a Storm Water Pollution Prevention Plan (SWPPP) which will be approved by the City of
Carlsbad and is to be followed through construction and impkmemation of the proposed project.
·i his SWPPP will indicate that the project construction activities will include appropriate
temporary erosion and sediment control protections so that all exposed soil in tile area of the
construction will be protected from erosion. This will include silt fem:es. sandbags and straw
mulch rolls being placed around excavated areas during the construction period, and storm drains
situated down:::.tream from the construction be protected by linear sedimem barriers or similar
erosion control devices. With the approval of and compliance with the SWPPP. the project will
not result in a significant impact from downstream sedimentation.
Additionally. City of Carlsbad Municipal Code Section 15.16 (Grading and Erosion Control)
requires that a pennittee enter into a security agreement to guarantee performance of 11MPs,
which are intended to protect on,;ite and downstream biology from impacts resulting rrom soil
ero:::.ion. Compliance with the requirements of the Grading and Erosion Control security
agreement reduces the potential for indirect impacts from ero:,ion control.
After construction. the project will provide on-site water quality treatment so as to avoid
discharge of polluted ,vater from the site. Thus. the project is not expected to result in permanent
significant downstream sediment impacts.
Invasive Species. The project has the potential to substantially affect the adjacent natural
hardlined area if project landscaping include::. invasive plants. Therefore the use of invasive plant
species in landscaping adjacent lo the conservation area will be prohibited. Also. irrigation runoff
shall be prevented from entering into the conservation areas from adjacent landscaping to reduce
nitrogen. introduce pesticides. or excess moisture. Only native or compatible non-invasive plant
species shall be used in landscaping. and no species listed on the California Invasive Plant
Council (Cal-I PC) list ~hall be used in landscaping or erosion control plans.
rcncing. Sign::. and Lighting. Increased human activity could re5ult in the potential for
trampling of vegetation outside of'thc permitted hmdline impact footprint, as well as soil
compaction. These factors could affect the viability and vigor of plant communities. which can
alter the ecosystem, creating gaps in vegetation, allowing non-native plant species to become
established. Trampling may also affect the rate of rainfall interception and evapotranspiration.
soil moisture. water penetration pathways. :::.urface flows, and erosion. /\n augmented human
presence increases the risk for damage to special-status wildlife species through habitat changes
as well a:, potential crushing of nests and altering species' behavior.

Unauthorized public access into open spaces can result in impacts which can significantly impact
the botany of the area. In order to restrict access into the preserved open spaces, permanent
fences will be constructed around the devclopmen1 which will discourage and prevent vehicle and
pedestrian access. Steel signs will be attached to the fences to provide notice that the area
constitutes an ecological preserve and that trespassing is prohibited except in authorized
locations.
J\lso, artificial night lighting exposes wildlife to unnatural light regime that may adversely affect
foraging patterns, increase predation risk, cause biological clock disruptions. and result in a
negative impact on species diversity. Therefore. lighting in or adjacent to the conservation area5
shall not be U<;cd except where essential for roadway. facility use, and safety. If night time
construction lights arc nece5sary. all lighting adjacent to natural habitat shall be shielded an<l/or
directed away from habitat. Permanent, po~t-construction lighting adjacent to the conservation area
shall also be reduced and/or shielded.
Noise. Construction-related noise could occur from equipment U!-,cd during vegetation clearing,
grading, and installation of infrao,tructure. Noise impacts can have a variety of indirect impacts on
wildlife species, including increa~cd stress, weakened immune systems. altered foraging behavior,
displacement due to startle. degraded communication with conspecifics (e.g .. masking), damaged
hearing from extremely loud noises, and increased vulnerability to predator. Indirect impacts from
construction-related noise may occur to sensitive wild] ife if construction occurs during the breeding
season (i.e .. February 15 through J\ugust 31 ). Excessive noise generation during construction should
be avoided.
Dust. Fugitive dust produced hy construction could disperse by wind into the adjacent native
vegetation, and thus may reduce the overall health and vigor of i11dividual plants by reducing their
photosynthetic capabilities. This. in turn, could affect animals depended on these plants. All projects
with the City of Carlsbad however, arc subject to the Grading Ordinance and must implement 8MPs
to reduce impacts from dust. These HMPs include, but arc not limited to, sprinkling v,.ater or dust
control agents during construction, covering trucks hauling dirt and debris, and other requirements.
Compliance with these factors wi!I reduce any dust-related indirect impacts to less than significant.
Chemical Pollutants. The introduction of chemical pollutants, such as herbicides, pesticides, or
insecticidco,, could result in potential impacts to special-status species through direct or indirect
corn;umption of the pollutant. Chemical pollutants also can degrade native habitats and water quality
over time. Therefore, the project ~hould ensure that construction employees limit their activities.
vehicles, and equipment an<l construction materials to the fenced project footprint area.
c. Will the project have a !iubstantial adverse effect 011 federal(r protected
wetlands as defined by Section 4fJ4 of the Clean Water Act (including, hut 1wt limited to,
marsh, riparian scrub, etc,) through direct remomt,Jilling, hy,lrological interruption or other
metms'!
Direct Impacts. Construction of the College Roulevar<l North Segment will permanently impact
0.12 acre and 385 linear feet of LJSJ\CE jurisdiction non-wetland "waters of the U.s'' at Little
Encinas Creek (See Figure 7; Juri.1dictional Impacts Map). Correspondingly. it will impact 0.12
acres and 385 linear feet ofCDF\V-jurisdictional area and RWQCH Jurisdiction non-wetland
"water5 of the state". These non-wetland wakrs of the U.S./State consist of a relatively narrm.v,
well-defined drainage \\·ith relatively steep banks and no surface water most of the year. The5e
impacts are analy?ed on the College Boulevard Reach A North Segment Jurisdictional

Thus, it is concluded that the impacts to Little Encina'> Creek 1.vill have a substantial adverse
effect on a fCdcrally protected wetlands [Waters of the U.S. in this caseJ as defined by Section
404 of the Clean \Vater Act through direc1 removal and filling, and mitigation will be required.
As a result, a Section 404 Permit (Nationwide Permit 14 if requested and approved) will be
required for the proposed project. Also, a CDFW Stream bed A Iteration Agreement under Section
1602 of the California Fish and (Jame Code is will also be required and a R\VQCB Section 401
certification must also be issued prior to commencement of the project. These rerrnits will
contain terms and conditions governing the nature of the impacts allowed. any compensatory
mitigation that may be required. and may include restrictions on the locations, methods. or timing
of project activities affecting the stream.
Indirect Impacts. No indirect impacts or adverse cffecb on federally protected wetlands as
defined by Section 404 or the Clean Water Act wil! result Crom implementation of the project
d. Will the project interfere substantial~r with the movement of any native resident or
migratoryfislt or wild life species or with e.,·tahlished native rnident or migratory wildNfe
corridors, or impede tlte use of native wil,llife nursery .,·itn?
Direct Impacts. The 4K Apartments site possesses an approved hardline pursuant to the
guidelines of the I-IMP. Although wildlif'c movement may he disrupted temporarily during
construction due to noise or increased human presence, these impacts are considered temporary in
nature, and implementation of the overall project will not result in permanent direct impacts to the
hard line or to wildlife movement functions. The pmtion of the properly within the hardline
conservation area wi I! be the subject of permanent conservation pursuant to the requirements of
the 1 lMP. In order to permanently conserve the property within the hardline. a conservation
easement will be required in conjunction \Vith the first final map, which will ensure permanent
protection of the conserved area. As a result. it is concluded that the project will not interfere
substantially with the movement of any native resident or migratory fish or wild life species or
with established native resident or migratory wildiifc corridors, or impede the use of native
wildlife nursery sites.
Further, it is concluded that the project wi!l not conflict with any local policies or ordinances
protecting biological resources, such as tree preservation policy or ordinance; and will not
connict with the provisions of the draft City of Carlsbad HMP, NCCP or other approved local,
regional or state habitat conservation plan.
Indirect Impacts. The project docs not have the potential 10 impact the movement of any native
re~ident or migratory fish or wildlife species or wildlife corridors. No indirect imract \\ill result
from implementation of the project.

resources, "'·uch as tree pre"'·ervation policy or oniinance?
Direct Impacts. The project does not conflict with local policies or ordinances prot,2cting
biological resources. Carlsbad docs not possess a tree preservation policy or ordinance. /\s a
result no direct impacb will result.
Indirect Impacts. The City of Carlsbad does not pos<;ess a tree preservation policy or ordinance
and therefore no indirect impacts will result

5.0 AVOIDANCE AND MINIMIZATION MEASURES
In order to avoid or minimi/c impacts to existing biological resources, it is recommended that the
project implement the following rnea5ures. These measures include mitigating for any potential
impacts to sensitive habitat. special-status plant and wildlife species,jurisdictional aquatic
resources, habitat linkages and corridors, conservation of protected habitats in perpetuity,
rninimi/.ation of human indirect impacts, and nesting birds protected under the Migratory Bird
Treaty Act.
• Impacts to upland vegetation communities shall be mitigated according to the mitigation
ratios outlined in the Carlsbad I IMP (City of Carlsbad, November 2004).
• The project applicant shall process and receive approval ofa lJ.S. Army Corps of
Engineers Section 404 permit, a California Dept. of Fish & Wildlife Strcambed Alteration
Agreement. and a Regional Water Quality Control Board Section 401 Certification for the
loss of0.12 acres of Waters of the U.S./State, which shall be mitigated as required by
those permits.
• The contractor should install temporary orange construction fencing (with silt barriers) at
the lirni ts of proj cct impacts (including construction staging areas and access routes J to
clearly demarcate the limits of disturbance and to prevent additional sensitive habitat
impacts and the spread of silt from the construction zone into adjacent habitats to be
avoided. The temporary construction fencing shall be removed upon project completion.
• A biological monitor should be present during any vegetation-clearing or overland travel
activities to avoid or minimize impacts to birds and other wildlife, as appropriate.
Clearing and grading of the site shall be avoided during the breeding season (February 15
to August 31) to the degree feasible. ln the event that these construction activities must
take place during the breeding sca'>on, no activities which v..ould result in noise levels
exceeding 60 d8A hourly Lcq within this 500-foot buffer shall be allowed. J\mbient noise
~hall be excluded from the 60 d8A calculation. If grading activities arc not completed
prior to the breeding season, and any of these species are present and noise levels exceed
the threshold, noise barriers shall be erected to reduce noise impacts to occupied habitat
to below 60 d£3/\ hourly Lcq or the activities shall be suspended.
• Construction employees will limit their activities, vehicles, equipment and construction
materials to the fenced project footprint. The applicant and the contractor shall execute a
construction contract that includes the following requirements; a) employees shall strictly
limit their activities, vehicles, equipmen1 and construction materials to the fenced project
footprint; b) the project site shall be kept as clean of debris as possible; c) pets of project
personnel shall not be allowed on the project site; d) disposal or temporary placement of
excess f1ll, brush or other debris shall not be allowed to be placed in the open spaces.
• If construction activities arc performed at night, lighting should be pointed away from
special-status habitat (i.e., coastal sage scrub habitat to the north) to minimize impacts to
wildlife.

• A Storm Water Pollution Prevention Plan (SWPPI') shall be prepared and followed
through comtruetion and implementation of the proposed project. This SWl'PP will
indicate that the project construction activities will include appropriate temporary erosion
and sediment control protections so that all exposed soil in the area of the construction
will be protected from erosion.
• The landscape mix for the project shall avoid the use of invasive plants in all areas
adjacent to the protected open space. The li-;t of invasive plants shall be those identified
by the California lnva5ive Plant Council (Cal-IPC) as moderate to high risk (Cal-lPC
2006) and specie,-known by the ~cicntific community to be locally invasive. Irrigation
runoff into the Preserve areas shall be preH.;nted in order to ensure that fertilizers and
pesticides/herbicide~ do not affect the natural vegetation or wildlife.
• The applicant :c.hall prepare and implement a perpetual management, maintenance. and
monitoring plan (PMP) for the onsite hardline conservation easement area. in c1ecordance
with the requirements of the Carlsbad HMP.
• In order to restrict human or domestic aninrnl access into the preserved open spaces,
permanent fences shall be constructed around the development which will discourage and
prevent vehicle and pedestrian access. Steel signs shall be attached to the fences to
provide notice that the area constitutes an ecological preserve and that trespassing is
prohibited except in authorized locations. Lighting in or adjacent to the conservation
areas shall not be used except where essential for roadway, facility use, and safety. lf
night time construction lights are necessary, all lighting adjacent to natural habitat shall
be shielded and/or directed away from habitat Post-construction lighting adjacent to the
conservation areas shall be limited and shielded.

JURISDICTIONAL DETERMINATION REPORT
For construction of the
COLLEGE BOULEY ARD REACH A NORTH SEGMENT
HOLLY SPRINGS DEVELOPMENT LLC
May 5, 2016
1.0 EXECUTIVE SUMMARY
This report summarizes Planning Systems' findings of U.S. Army Corps of Engineers
("USACE"), California Department of Fish and Wildlife ("CDFW") and the Regional Water
Quality Control Board ("RWQCB") jurisdiction for the College Boulevard Reach A North
Segment project. This jurisdictional determination (or delineation) work was performed by
regulatory specialists from Planning Systems on April 19, 2016. The delineation was conducted
of the area in and around Little Encinas Creek which is proposed to be impacted by construction
of the College Boulevard Reach A North Segment. The Reach A North Segment is an
approximate 1,200 linear foot section of proposed College Boulevard, a public roadway within
the City of Carlsbad.
This delineation covers the area of construction of the proposed roadway segment and also
extends approximately 200 feet beyond the construction limits on Little Encinas Creek in both the
east and west directions. The purpose of this report is to verify whether the field conditions in the
project area confirm the findings documented in the previous (Recon 2001) delineation of the
same area. Planning Systems' Director of Planning and Regulatory Analyst Paul Klukas
conducted the survey investigation. The findings of the Recon 2001 delineation {Final EIR for the
Calavera Hills Master Plan Phase II, Bridge and Thoroughfare District No. 4, & Detention Basin,
Recon, November, 2001) and a later College Boulevard Reach A Biological Resources Report,
by Merkel & Associates, Inc., March 19, 2010, both concluded that Little Encinas Creek in this
area constitutes a "non-wetland jurisdictional waters" per both the federal and the state
jurisdictional guidelines. This updated Planning Systems' analysis concurs with these earlier
findings. More specifically, the Planning Systems' field analysis concludes that the edge limits of
non-wetland "waters of the U.S." in Little Encinas Creek are identified by the presence of an
ordinary high water mark {OHWM) on the outer edges of the channel, and the limits of CDFW
jurisdictional "waters of the state" are identified as the top of the channel bank. Investigation for
wetland features concluded that no wetlands occur in the area impacted by the project.
This jurisdictional delineation concludes that the College Boulevard Reach A North Segment
project will permanently impact 0.12 acre and 385 linear feet ofUSACEjurisdiction non-wetland
"waters of the US". Correspondingly, it will impact 0.12 acres and 385 linear feel ofCDFW-
jurisdictional area and 0.12 acres and RWQCB Jurisdiction non-wetland "waters of the state".
A Section 404 Permit (Nationwide Permit 14 if requested and approved) will be required for the
proposed project. Also, a CDFW Streambed Alteration Agreement under Section 1602 of the
California Fish and Game Code is will also be required. Thirdly, a RWQCB Section 401
certification must also be issued prior to commencement of the project. These permits will
contain terms and conditions governing the nature of the impacts allowed, any compensatory

mitigation that may be required, and may include restrictions on the locations, methods, or timing
of project activities affecting the stream.
2.0 PROJECT DESCRIPTION
The Holly Springs residential project (single and multifamily homes) has been reviewed, certified
for CEQA review, and approved by the City of Carlsbad. The approved plans for the Holly
Springs project require the developer to achieve vehicular access to the development site through
the construction of College Boulevard Reach A. The Holly Springs developer is proposing that
this be achieved through construction of a northerly extension of approximately 1,200 linear feet
of College Boulevard, connecting the existing intersection of College Boulevard and Cannon
Road to the subdivision. The subject Project and roadway are located in the City of Carlsbad,
San Diego County, California. (See Figure I; Vicinity Map). Construction of the College
Boulevard North Segment will traverse Little Encinas Creek, which is depicted as a blue-line
drainage on the U.S. Geological Survey ("USGS") topographic map San Luis Rey, California
(2016). Please see Figure 2; USGS Map.
This delineation report provides regulatory information, methods, and results in an effort to
confirm or revise findings of the previous delineation of jurisdictional waters (Recon 2001 and
Merkel & Associates 2010) potentially impacted by the College Boulevard "Reach A" North
Segment ("project"). The purpose of this confirming delineation is to again assess the limits of
state and federal jurisdiction which will be impacted by the project. However, the earlier
analyses did no break the Reach A North Segment out from the balance of the several related
projects in the area. This present wetland delineation report describes the resources subject to
regulation by the USACE, CDFW and the RWQCB that will be significantly impacted by the
Reach A North Segment only. This delineation is being conducted on behalf of Holly Springs
LLC, the owners of the Holly Springs residential project.
The project involves construction of approximately 25% of the length of future College
Boulevard Reach A. The entirety of College Boulevard Reach A is a City approved Circulation
Element roadway identified as a major arterial divided roadway within a 102-foot right-of-way.
The full Reach A project was previously negotiated and permitted by the federal and state
regulatory agencies based upon the 2001 Final EIR for the Calavera Hills Master Plan Phase II.
Bridge and Thoroughfare District No. 4, & Detention Basin (RECON 2001); however, the federal
and state pennits have since expired. Presently, only the North Segment is proposed to be
constructed in order to access the approved Holly Springs residential development east of the
proposed roadway. Please see Figure 3; Project Location Map.
The 2001 jurisdictional delineation concluded that wetlands and waters of the US and state would
be impacted by construction of the entirety of Reach A. As mentioned however, this delineation,
and the Merkel 20 IO delineation subsequently, did not however break down the impacted areas to
a degree sufficient to assess impact acreage for the North Segment separately. This proposed
construction of the North Segment would require the crossing of Little Encinas Creek. A culvert
would be placed over this drainage to ensure continued stream conveyance. It is the intent of this
present jurisdictional delineation to address delineation of construction of this North Segment of
College Boulevard only.

2.1 Project Location
PS Job #150514
May 5, 10/6
The proposed College Boulevard "Reach A" North Segment is located within the northeast
quadrant of the City of Carlsbad, California. A portion of this street segment must traverse the
Little Encinas Creek drainage channel, located at Township 11 south, Range 4 west of the U.S.
Geological Survey (USGS) 7.5' San Luis Rey, California Quadrangle. The affected property is
mostly within roadway right-of-way property owned by the City of Carlsbad, located between
APN 168-050-35 and 168-050-36. The grading and drainage improvements associated with
construction of the roadway segment will extend not only with.in the City right-of-way, but also a
small distance into these adjacent parcels owned by the Rancho Carlsbad Owners Association.
The Reach A North Segment construction site is located at 33.154123 degrees north latitude and
117.285908 degrees west longitude. The project site is located within the USACE's Arid West
region.
The project is located within the Carlsbad Hydrologic Unit of the San Diego Hydrologic Region.
The Carlsbad Hydrologic Unit is a triangular area of approximately 210 square miles (134,400
acres), extending from Lake Wohlford in east San Diego County, west to the Pacific Ocean; and
from the City of Vista on the north to south Encinitas on the south. The Carlsbad Hydrologic
Unit is further divided into six watersheds. The project site is within the Agua Hedionda Creek
watershed, which originates in the hills south of the San Marcos Mountains and flows in a
generally southwest direction to where it ultimately discharges at the Agua Hedionda Lagoon.
Little Encinas Creek is a tributary to the Agua Hedionda Creek within this watershed.
The project area spans from the intersection of Cannon Road and College Boulevard, south
approximately 1,200 feet through undeveloped lands to a proposed collector roadway which will
access the Holly Springs residential development to the east, and a temporary cul-de-sac. The
construction site is located just east of Rancho Carlsbad Mobile Home Park (RCMHP) and
primarily consists of developed (RV storage lot and adjacent tennis courts and grass play fields)
and agricultural (community garden) fields. Upstream of the Reach A North construction zone,
non-native grasslands and sage scrub vegetation communities are distributed throughout the
hillsides. The site is located in the inland portion of the Agua Hedionda Creek Watershed,
approximately two miles upstream of Agua Hedionda Lagoon. Little Encinas Creek, a tributary
to Calavera Creek, conveys water in a westerly direction through the project area. This tributary
merges with Calavera Creek only 150-feet west of the project, which then merges with Agua
Hedionda Creek further to the west.
2.2 Project History
In 2001, the entirety of College Boulevard Reach A was a project element in the Final
Environmental Impact Report for the Calavera Hills Master Plan Phase II, Bridge and
Thoroughfare District No. 4, & Detention Basin (SCH #99111082). The EIR was certified by the
City Conncil on January 14, 2002 and subsequently applied and received federal and state pcnnits
as a result of impacts to wetlands and non-wetland jurisdictional waters of the U.S. [i.e., Section
404 (Permit No. 200100215-RLK), Section 401 (Certification No. R9-2002-0014), and Section
1600 (Agreement No. R5-200l-0007]. These permits covered the entirety of College Boulevard
Reach A. The permits were extended for some period of time since the roadway was never built.
An updated biological report was prepared in 2010 (Merkel & Associates, 2010) to verify that no
significant changes to the biology of the area had occurred since the original CEQA document
and pennit issuance. However in 2007 the USACE determined that the Section 404 permit had

expired. The remaining permits have since ultimately also expired and therefore new federal and
state permits are required.
2.3 Purpose and Need for the Project
The purpose of the proposed project is to provide access to medium-high density and low density
residential housing which would achieve the following goals:
• The project will provide access to the approved Holly Springs medium-high density and
low-medium density residential areas.
• The Holly Springs residential uses will help satisfy the affordable housing requirements
of the City of Carlsbad.
• The Holly Springs residential uses establish a comprehensive development plan for the
area and are consistent with the City of Carlsbad General Plan.
• The project will encourage new development consistent with the capacity and municipal
service capabilities.
• The project will facilitate the movement of people and vehicles within and through the
City.
• The project will accommodate new development in a phased, orderly manner and is
coordinated with the provision of necessary infrastructure and public improvements.

3.0 REGULATORY AUTHORITY
PS Job #/50514
May 5, 2016
Streams and waterways, including ephemeral drainages, dry streambeds, and wetlands, can
possess unique ecological functions and wlues, and are protected from human-induced
destruction or degradation by a number of federal and state statutes. The federal and state
agencies charged with administering these statutes and their responsibilities are described b1iefly
below.
3.1 FEDERAL REGULATIONS
3.1.1 Clean Water Act-Section 404
Pursuant to Section 404 of the Clean Water Act ("CWA"), the USAGE regulates the discharge of
dredge and/or fill material into waters of the United States. Section 404 of the CW A requires that
any person proposing any activity that would discharge these materials must first obtain a permit
from the USACE. For discharges proposed in the project region, Section 404 Pennits are issued
by the USACE's Los Angeles District. The CWA stipulates that the USACE may not issue a
Section 404 Permit if the proposed activity would be contrary to the public interest or would
cause substantial degradation of the nation's waters, or if a less environmentally damaging
practicable alternative exists.
Waters of the U.S. generally include navigable waterways and wetlands adjacent to navigable
waterways, non-navigable tributaries to navigable waterways, and wetlands adjacent to non-
navigable waters that are contiguous with navigable waterways. Regulatory definitions of
wetlands and waters of the U.S., as well as recent Supreme Court decisions affecting the
interpretation of those definitions, are discussed below.
3.1.1.1 WatersoftheUnitedStates
The term "waters of the U.S." is defined in regulations promulgated by the USACE under the
authority of the CWA and typically includes all navigable waters (including all waters subject to
the ebb and flow of the tide); all interstate waters and wetlands; all impoundments of waters
mentioned above; all tributaries to waters mentioned above; the tenitorial seas; and, all wetlands
adjacent to waters mentioned above.
However, recent Supreme Court decisions have curtailed CW A jurisdiction in some cases, as
described below. In water bodies and streambeds lacking adjacent wetlands, the lateral extent of
the USACE's jurisdiction is bounded by the Ordinary High Water Mark (OHWM). The OHWM
is defined at 33 CFR 328.3(e) as "that line on the shore established by the fluctuations of water
and indicated by physical characteristics such as a clear, natural line impressed on the bank,
shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of
liner and debris, or other appropriate means that consider the characteristics of the surrounding
areas." Where adjacent wetlands are present, jurisdiction under the CW A extends laterally to the
landward edge of the adjacent wetlands. The upstream/downstream limit of CWA jurisdiction is
the point beyond which the OHWM is no longer perceptible due to the lack of a bed and bank or
other distinguishing features.

Jurisdiclio11a/ Deten11i11allo11 Report 8
PS Job #150514
May 5, 20/6
In the last decade, two important decisions by the U.S. Supreme Court have limited the scope of
CWA jurisdiction. In 2001, the court ruled in Solid Waste Agency of North Cook County v.
United States Army Corps of Engineers ("SW ANCC") that the USACE exceeded its statutory
authority by asserting CWA jurisdiction over "an abandoned sand and gravel pit in northern
Illinois, which provides habitat for migratory birds." This ruling invalidated the 1986 "Migratory
Bird Rule" detennined that CWA jurisdiction does not extend to waters that are non-navigable,
isolated, and intrastate.
As a result of the SW ANCC case, the U.S. Supreme Court held that USA CE may not specifically
rely on the Migratory Bird Rule to establish a significant nexus to interstate or foreign commerce.
Although no formal guidance was issued by USACE interpreting the extent to which the
SW ANCC decision would limit jmisdictional detenninations, in practice, USACE considers
intrastate waters as waters of the U.S. where there is an appropriate connection to a navigable
water or other clear interstate commerce connection. Therefore, waters of the U.S., including
jurisdictional wetlands, must show connectivity with (be tributary to) a navigable waters of the
U.S. to be subject to USACE under Section 404 of the CW A.
Later, in 2007, in Rapanos v. United States and Carabell v. United States (consolidated cases),
the question was whether CWAjurisdiction extends to wetlands that do not contain, and are not
adjacent to, waters traditionally understood as "navigable." The Court issued two controlling
opinions in this case, specifying conditions under which ephemeral and intermittent tributaries
and adjacent wetlands are subject to CWA jurisdiction. In the wake of these decisions, the
Environmental Protection Agency (''EPA") and the USACE have together issued a joint guidance
memorandum clarifying CW A jurisdiction. The guidance identifies those waters over which the
agencies (USACE and EPA) will assert jurisdiction categorically and on a case-by-case basis.
Under nonnal conditions, it was detennined that USACE will assert jurisdiction over the
following features:
• Traditional navigable waterways and their adjacent wetlands.
• Non-navigable tributaries of traditional navigable waterways that typically flow year-
round or have a continuous flow at least seasonally (typically 3 months) and wetlands that
directly abut such tributaries.
• Non-navigable tributaries that do not typically flow year-round or have continuous flow
at least seasonally, wetlands adjacent to such tributaries, and wetlands adjacent to but not
directly abutting a relatively permanent non-navigable tributary.
Alternatively, the USACE will typically not assert jurisdiction over the following features:
Swales or erosional features (e.g., gullies and small washes characterized by low volume
and infrequent or short-duration flows).
• Ditches (including roadside ditches) excavated wholly in uplands and draining only
uplands that do not carry a relatively pennanent flow of water.
3.1.1.2 Wetlands
Wetlands are defined in USACE regulations at 33 CFR 328.3(b) as "those areas that are
inundated or saturated by surface or ground water at a frequency and duration sufficient to
support, and that under normal circumstances do support, a prevalence of vegetation typically
adapted for life in saturated soil conditions." In 1987, the USACE published the Corps of
Engineers Wetland Delineation Manual (Environmental Laboratory 1987; Wetland Delineation
Holly Sp,·ings Coflege Blvd. Rench A North Segment

Manual) to guide its field personnel in detennining jurisdictional wetland boundaries. In 2008,
the USACE published the Regional Supplement to the Corps of Engineers Wetland Delineation
Manual: Arid West Region (USACE 2008; Arid West Regional Supplement) to complement the
Westland Delineation Manual in the southwestern U.S. The methods set forth in the Wetland
Delineation Manual and the Arid West Regional Supplement provide that the delineation of
wetlands be based on the presence of three wetland parameters together: a predominance of
hydrophytic vegetation; hydric soils; and wetland hydrology. These wetland parameters are
discussed below.
Hydrophytic Vegetation. A site is considered to have a "predominance of hydrophytic
vegetation" at a location if greater than 50 percent of all the dominant species present within the
vegetation unit have a wetland indicator status of obligate ("OBL"), facultative wetland
("FACW"), or facultative ("FAC"). An OBL indicator status refers to plants that have a 99%
probability of occurring in wetlands under natural conditions. A F ACW indicator status refers to
plants that usually occur in wetlands (67% to 99% probability) but are occasionally found
elsewhere. A FAC indicator status refers to plants that are equally likely to occur in wetlands or
elsewhere (estimated probability 34% to 66% for each). The wetland indicator status used for this
report follows the National List of Plant Species that Occur in Wetlands: California (Reed; U.S.
Fish And Wildlife Service 1988).
Hydric Soils. Hydric soils are defined as "soils that formed under conditions of saturation,
flooding, or ponding long enough during the growing season to develop anaerobic conditions in
the upper part" (USDA-NRCS 1994). The hydric soil criterion is satisfied at a location if soils in
the area can be inferred or observed to have a high groundwater table. if there is evidence of
prolonged soil saturation, or if there are any indicators suggesting a long-term reducing
environment in the upper 18 inches of the soil profile. The Wetland Delineation Manual and Arid
West Regional Supplement describe visual and textural indicators ofhydric soils used in the field
to determine the presence of hydric soils. In most situations, only one of these indicators is
required to make a positive detennination.
Wetland Hydrology. Wetlands are characterized by various hydrologic regimes that range from
permanently inundated to irregularly inundated or saturated. In other words, some wetlands are
always wet while other wetlands may contain water during only part of the year. For an area to
have "wetland hydrology," as defined in the Wetland Delineation Manual, the area must be
"inundated or saturated to the surface for at least 5% of the growing season in most years." In the
Arid West Region, the minimum threshold for wetland hydrology under most circumstances is 14
or more consecutive days of flooding or ponding, or a water table 12 inches or less below the soil
surface, during the growing season at a minimum frequency of 5 years in 10. The Wetland
Delineation Manual and Arid West Regional Supplement describe visual indicators of wetland
hydrology used in the field to determine the presence of wetland hydrology. Where either a single
primary indicator or two secondary indicators are observed, a positive determination for wetland
hydrology is made.
3.1.2 Clean Water Act-Section 401
Pursuant to Section 401 of the CWA; " ... any applicant for a federal pennit for activities that
involve a discharge to waters of the United States shall provide the federal permitting
agency a certification from the state in which the discharge is proposed that states that the
discharge wiU comply with the applicable provisions under the federal Clean Water Act."
Therefore, before USACE will issue a Section 404 pennit, applicants must apply for and receive
Section 401 water quality certification or a waiver from the RWQCB, as applicable. Under
Holly Springs College Blvd. Reach A Norlh Segment
Jurisdic//0110/ Derem1inat/011 Report IO
PS Job #1505/4
May 5, 20/6
Section 401, the RWQCB regulates at the state level all activities that are regulated at the federal
level by USACE. Therefore, RWQCB jurisdiction usually coincides with the jurisdictional
boundaries for waters of the U.S. However, if a drainage is determined not to be waters of the
U.S., they may still be subject to RWQCB jurisdiction based on the state of California Porter-
Cologne Act (discussed below).
3.2 STATE REGULATIONS
The State of California also regulates activities involving rivers, streams or lakes or wetlands or
riparian habitats associated with these features. These regulations are described in the following
sections.
3.2.1 California Fish and Game Code
Pursuant to Sections 1600-1616 of the California Fish and Game Code, CDFW regulates any
activity that will substantially divert or obstruct the natural flow-or substantially change or use
any material from the bed, channel, or bank-of any river, stream, or lake. CDFW also regulates
any activity that will deposit or dispose of debris, wastewater, or other material containing
crumbled, flaked, or ground pavement that may pass into any river, stream, or lake. The
applicant must notify CDFW prior to such activities and obtain a Lake or Streambed Alteration
Agreement.
CDFW jurisdiction includes ephemeral, intermittent, and perennial watercourses (including dry
washes) and lakes characterized by the presence of; (a) definable bed and banks and (b) existing
fish or wildlife resources. Furthermore, CDFW jurisdiction is often extended to habitats adjacent
to watercourses, such as oak woodlands in canyon bottoms or willow woodlands that support
hydrologic functions within the riparian system.
Water features such as vernal pools and other seasonal swales where the defined bed and bank are
absent and the feature is not contiguous or closely adjacent to other jurisdictional features are
generally not jurisdictional under Section 1602. CDFG generally does not assert jurisdiction over
human-made water bodies unless they are located where such natural features were previously
located or where they are contiguous with existing or prior natural jurisdictional areas.
The CDFW jurisdiction within altered or artificial waterways is based upon the value of those
waterways to fish and other wildlife. Generally:
Natural waterways that have been subsequently modified and which have the potential to
contain fish, aquatic insects and riparian vegetation will be treated like natural waterways;
Artificial waterways that have acquired the physical attributes of natural stream courses and
which have been viewed by the community as natural stream courses should be treated by
CDFW as natural waterways;
Artificial waterways without the attributes of natural waterways should generally not be
subject to Fish and Game Code provisions.
CDFW jurisdictional limits are not as clearly defined by regulation as those of the USACE.
While they frequently closely resemble the limits described by USACE regulations, the also
include riparian habitat supported by a river, stream or lake regardless of the presence or absence
of hydric and saturated soils conditions. In general, the CDFW takes jurisdiction from the top of
Hoffy Spri11gs College Bfwf. Reach A North Segme11t
J11risdictio11al Detenninatiou Report 11
PS Job #/50514
May 5, 2016
a stream bank or to the outer limits of any adjacent riparian vegetation, whichever is greater.
Notification to CDFW is generally required for any project that will take place within or in the
vicinity of a river, stream, lake, or their tributaries. This includes rivers or streams that flow at
least periodically or pennanently through a bed or channel with banks that support fish and other
aquatic plant and/or wildlife species. It also includes watercourses that have a surface or
subsurface flow that support or have supported riparian vegetation.
3.2.2 Porter-Cologne Water Quality Control Act
In 1969, the State of California enacted the Porter -Cologne Water Quality Control Act. Under
this statute, the RWQCB regulates discharges of pollutants into "waters of the state", which are
broadly defined as any surface water or groundwater, including saline waters, within the
boundaries of the state. This authority is independent of any federal requirements, and is
applicable to all waters of the state regardless of whether CWA jurisdiction applies. To ensure
that California's isolated waters are protected and that the pennitting process is as efficient as
possible, the SWRCB has issued general Waste Discharge Requirements regulating discharges to
"isolated" waters of the state that are not under federal CWA jurisdiction (Water Quality Order
No. 2004-0004-DWQ, Statewide General Waste Discharge Requirements for Dredged or Fill
Discharges to Waters Deemed by the USACE to be Outside of Federal Jurisdiction).

4.0 STUDY METHODS
PSJob#/50514
May 5, 2016
Waters of the U.S., CDFW-jurisdictional streambeds, and waters of the state within the College
Boulevard Reach A North Segment project site were delineated using a combination of desktop
literature review and field mapping methods.
4.1 LITERATURE REVIEW
Prior to field efforts, the United States Geologic Survey (USGS) San Luis Rey, CA 7.5 minute
quadrangle map (USGS 2016), the Soil Survey Geographic Database for the San Diego County,
California, and a high quality aerial photograph of the Project site and the surrounding area were
reviewed to detennine the locations of potential hydrologic features. The jurisdictional
delineation analysis in the Final Enviromnental Impact Report (EIR) for the Calavera Hills
Master Plan Phase II, Bridge and Thoroughfare District No. 4, & Detention Basin (SCH
#99111082) was reviewed for designated drainages, vegetation and wetlands. Further, the
College Boulevard -Reach A Biological Resources Report, by Merkel & Associates, Inc., March
19, 2010 was also reviewed for the same information. Additionally, a reconnaissance-level
survey was conducted on April 19, 2016 by Planning Systems' biologists and regulatory
specialists to detennine potentially-jurisdictional areas.
The upper reaches of Little Encinas Creek, east of the subject area, are shown as a blue line
stream in the USGS 7.5 minute San Luis Rey Quadrangle Map (2015). Calavera Creek,
downstream from Little Encinas Creek and Agua Hedionda Creek, downstream from Calavera
Creek, are also both identified as a blue line stream. The project construction area for College
Boulevard Reach A North Segment is indicated as a fragmented blue line stream on the USGS
Map.
4.2 DELINEATION OF WATERS OF THE UNITED STATES
A fonnal wetland delineation and jurisdictional detennination of waters of the U.S., waters of the
state, and CDFW-jurisdictional streambeds was performed on the project site on April 19, 2016
(time: 0900-1430; weather: temperature ranged from 71 °F to 80°F, wind ranged from 4 mph
[SWJ to 8 mph [W]). The methods used during the field surveys are described below. Following
completion of the surveys, watershed maps, aerial photographs, and other applicable literature
were reviewed to ascertain whether waters identified in the field were isolated, or rather were
tributary to navigable waters.
The scope of the project jurisdictional delineation assessment is within a very limited area in
which College Boulevard Reach A North Segment is proposed to be constructed. The
construction limits traverse existing Little Encinas Creek, which at the time of survey consisted of
a relatively narrow, well-defined drainage possessing, traveling east to west, with relatively steep
banks and no surface water. Little Encinas Creek is the only potential water of the U.S. within
the area surveyed and proposed for College Boulevard Reach A North Segment construction. An
OHWM was identifiable near or at the top of the channel banks. No wetland features were
detected outside of the OHWM of the creek. Little Encinas Creek is well-channelized and
confined by apparently artificially-created small berms on the exterior top of the banks on both
sides through the subject construction area. The banks of the creek are steep and lacking in
vegetation. Documentary evidence suggests that similar conditions existed at the site during the
Recon 2001 and the Merkel & Associates 2010 delineation site surveys.

Jurisdic1io11al Determination Reporl 13
PS Job #150514
May 5, 2016
4.2.1 Ordinary High Water Mark
USACE regulations define the term "ordinary high water mark" for purposes of the CW A lateral
jurisdiction at 33 CFR 328.3(e), which states:
"The term ordinary high water mark means that line on the shore established by
the fluctuations of water and indicated by physical characteristics such as a clear,
natural line impressed on the bank, shelving, changes in the character of soil,
destruction of terrestrial vegetation, the presence of litter and debris, or other
appropriate means that consider the characteristics of the surrounding areas."
The extent of non-wetland waters on Little Encinas Creek was determined based on the location
of the OIIWM. The channel and banks of Little Encinas Creek were examined for signs of flow,
terraces, drift deposits, changes in vegetation, and other indicators that would determine the
location of the OHWM. Once the OHWM was identified in the field, the boundary was walked
with a Trimble GeoXH Geoexplorer 2008 handheld GPS unit set to collect positional data. Upon
completion of field data collection, jurisdictional boundaries were downloaded from the GPS unit
and converted into a GIS shape file using ArcGIS software. Properties such as length, width, and
acreage of the drainage were calculated through ArcGIS. Photographs were taken to document
site conditions (Appendix A).
In addition to the Little Encinas Creek hydrologic feature indicated on the USGS quadrangle map
and found during the field survey, the project site was surveyed for any additional hydrologic
features. No other qualifying hydrologic features were identified.
4.2.2 Vegetation Mapping
The study area was assessed in such a manner as to view all areas to the degree necessary to
detennine the presence or absence of wetland vegetation. Habitat within the immediate region
consists predominately of urban development, ornamental landscape or agricultural fields. Some
upstream inclusions of native upland communities, as well as non-native upland communities
exist. Much of the extensive agriculture in the surrounding area has been mapped as such due to
historical crop farming, most of which has ceased production activities but has been maintained
yearly via discing and mowing of the land to sustain fallow agricultural conditions. A limited
amount of Diegan coastal sage scrub is located on the hillsides upstream from the project area. It
is concluded that no substantive wetland vegetation, and no substantive native vegetation at all
occurs within or adjacent to the Little Encinas Creek channel.
4.3 DELINEATION OF CDFW-JURISDICTIONAL STREAMBEDS
The extent ofstreambeds falling under the jurisdiction of the CDFW pursuant to section 1600 et
seq. of the California Fish and Game Code was determined based on the presence of a defined
physical bed, banks, and channel. No riparian vegetation was present within or adjacent to the
streamcourse, and vegetation was therefore not used as a determining characteristic. Upon
investigation, no significant distinction between the OHWM and the top of the CDFW-
jurisdictional stream bank was evident. Thus, the GIS shapefiles created from the OHWM
boundaries were determined to be coterminous with the extent of CDFW jurisdiction within the
drainage.

The extent of waters of the state on-site subject to the authority of the RWQCB under the Porter-
Cologne Water Quality Control Act was determined to be cotenninous with the extent of CDFW
jurisdictional streambeds, due to the simple nature of the channel and the absence of any aquatic
features that would be under the jurisdiction of one agency but not the other. Therefore, the
shape files representing CDFW jurisdiction were also used to calculate the extent of waters of the
state.

5.0 RESULTS
PS Job #/50514
May 5, 2016
Results of the wetland delineation and jurisdictional detennination are presented below. An
overview of the site's vegetation, hydrology, and soils is presented, followed by a description of
the jurisdictional areas identified during the delineation.
5.1 SITE INVESTIGATION
This section provides an overview of the existing vegetation, soils, and hydrology within the
project site, to provide a context within which to understand the delineation results. The area
investigated can be described as a relatively narrow streambed with steeply eroding banks with
minor benching and almost no vegetation growth. The streambed is bounded on the north by
agricultural lands and on the south by Rancho Carlsbad Mobile Home Park improvements.
5.1.1 Vegetation
The area of proposed project construction would be considered sparse Ruderal vegetation and
Eucalyptus grove. The soil in and around the channel is sandy and almost totally unvegetated
with some minor inclusions of non-native grassland species. For the purposes of this report, this
channel has been classified as an unvegetated streambed. At both the eastern and western
sections of the construction area, small groves of several Red gum eucalyptus (Eucalyptus
camaldulensis) trees exist. Throughout the channel and adjacent environment, the area has been
developed and regularly maintained, presumably for efficiency of drainage transport, for
reduction of fire hazard, and for domestic landscape aesthetics. The entire area is highly
disturbed from a natural condition. A number of annual non-native, ruderal weeds occur within
and around the channel. These weeds include Annual sowthistle (sonchus oleraceus), Common
cocklebur (Xanthium strumarium), Tumble mustard (Sisymbrium altissimum), Little mallow
(Malva parviflora), Common groundsel (Senecio vulgaris), Dandelion (Taraxac11m officinale),
Shepherd's-purse (Capsella bursa-pastoris), and London rocket (Sisymbd11m irio). A single
native Spiney rush (Juncus acutus) plant (approximately 3-feet in diameter) is growing in the
channel bottom within the construction area. Directly adjacent to and along the berm on the
south side of the streambed several non-native Spineless Yuccas (Yucca elephantipes) have been
planted as domestic landscaping and have grown to approximately 15-feet in height. None of the
vegetation species within the construction zone are native to the area with the exception of the
single Spiney rush plant. Approximately 100-feet upstream of the construction zone, an isolated
area of Coastal Sage Scrub vegetation, including Laurel sumac (Malosma laurina), Flat top
buckwheat (Eriogon11mfascicilat11111) and Lemonade Berry (Rh11s integrifolia) occurs adjacent to
the north side of the streambed. This native area, however is east of the proposed construction
zone and none of these native plants will however be impacted by the proposed roadway
construction. In the area of the proposed project, the Little Encinas Creek and immediate
surrounding environs possesses little biological value (Merkel & Associates, 2010).
5.1.2 Soils
The project site is located in eastern Carlsbad, California. This area is characterized by relatively
flat-lying rolling topography, with valley fill alluvial deposits. Based on the soil survey
geographic (SSURGO) database for San Diego County the soil type in the area of the project is
Huerhuero loam (HrD), 9% to 15% slopes, although the slope of the soil surface in the subject
area is of a lesser-degree slope and almost flat.
Holly Springs College Blvd. Reach A North Segmem
J11risdic1io11al Detenni1mlion Reporl 16
PSJob#/50514
May 5, 2016
The Huerhuero series consist of moderately well drained loams that have clay subsoils. These
soils developed in sandy marine sediments, and they have very slow infiltration rates. The soils
are clayey, have a high water table, or are shallow to an impervious layer. The Huerhuero series
within the site is not identified as normally hydric soil (Natural Resources Conservation Service
(20 l 0). The streambed channel substrate at the bottom is loose and unconsolidated, mostly sand.
The bank substrate is consolidated sand to cobble. Granite and concrete rocks have been
artificially thrown into the channel in one location, presumably to reduce drainage water velocity.
5.1.3 Hydrology
The project site is within the Agua Hedionda Creek watershed, which drains to the west into
Agua Hedionda Lagoon, located approximately 2 miles to the west. The drainage system in the
area of proposed construction is well-defined by a single drainage called Little Encinas Creek.
Little Encinas Creek is a tributary into Calavera Creek, which flows as a larger tributary into
Agua Hedionda Creek. Agua Hedionda Creek is a perennial stream, containing at least a small
amount of water year round. Calavera Creek, which flows down from the north, is also a
perennial stream, with water level being largely detennined by releases of impounded water from
the Calavera Dam, located upstream, in the northeast comer of the City of Carlsbad.
In the location of the subject project, the terrain drains generally east to west. Little Encinas
Creek is the only substantive drainage in the immediate area, and is described as an unvegetated
ephemeral stream channel, draining the upper elevations of eastern Carlsbad, which are largely
covered by native Diegan coastal sage scrub and Chaparral plant communities, to the downstream
residential neighborhood, under El Camino Real and into Agua Hedionda Lagoon. Agua
Hedionda Lagoon is considered a navigable waterway, directly connected to the Pacific Ocean.
As such, Little Encinas Creek is directly tributary to a definable navigable waterway.
Little Encinas Creek is an intennittent or ephemeral stream, likely to only receive stream flow
during and following significant rain events. Carlsbad is characterized by a moderate climate
with warm, dry summers and cool winters with occasional rainstorm events. Average monthly
precipitation ranges from 2.52 inches in January to 0.08 inches in August. The average annual
precipitation in Carlsbad is 11.85 inches (Western Regional Climate Center, 2010). Little
Encinas Creek conveys surface water only occasionally.
5.2 JURISDICTIONAL DRAINAGE
Assuming an OHWM and the extant hydrologic connection with a definable "navigable waters of
the United States," the Little Encinas Creek falls under the jurisdiction of the ACOE. Since this
creek (including the subject project area) is directly tributary to Calavera Creek, which is
tributary to Agua Hedionda Creek, which is directly tributary to Agua Hedionda Lagoon, which is
directly tributary to the Pacific Ocean; Little Encinas Creek meets the jurisdictional definition of
"waters of the United States," pursuant to Section 404 of the CW A.
CDFW jurisdiction includes the streambed and channel, extending to the top of the bank, and to
the outward extent of the canopy of riparian vegetation, if a riparian canopy is present. Therefore
the channel bed to the upper reach of the bank is regulated by CDFW. No riparian vegetation
exists, and therefore no extension of jurisdictional limits exists beyond the top of the channel
bank. A delineation of ACOE and CDFW jurisdictional areas for the subject project construction
area is shown in Figure 4 Existing Jurisdictional Area and referenced in Table 1; Existing
Jurisdictional Area provides a description of the stream channel jurisdictional area.

5.3 JURISDICTIONAL WETLANDS
No jurisdictional wetlands were observed on-site.
5.4 SUMMARY OF REGULATORY AGENCY JURISDICTION
As described above, the Little Encinas Creek within the Project site contains an ephemeral
strcambed which exhibits clear bed and bank characteristics. This ephemeral stream is tributary to
a navigable body of water (Calavera Creek to Agua Hedionda Creek to Agua Hedionda Lagoon)
and thus is not isolated. As a result, no hydrophytic vegetation, hydric soil, or wetland hydrology
was observed on-site, no USACE-jurisdictional wetlands are present within the Project site.
A summary of the total acreage of waters subject to the pennitting authority of the USACE,
CDFW, and the RWQCB is presented below. The jurisdictional areas are displayed on Figure 4;

5.4.1 Waters of the United States
The Little Encinas Creek is an incised, ephemeral channel which conveys drainage from eastern
Carlsbad to western Carlsbad. This creek exhibits the defined beds and banks which are
jurisdictional to the USACE as non-wetland waters of the U.S. A total of 0.12 acres and 385
linear feet of waters of the U.S. will be impacted by construction of the Reach A North Segment.

5.4.2 Waters of the State
PSJob#/50514
M(/y5, 2016
Little Encinas Creek exhibits defined beds and banks, and thus this streambed constitutes a waters
of the state. The jurisdictional acreage in these areas under the Porter-Cologne Water Quality
Control Act was determined to be coterminous with the extent of CDFW jurisdictional
streambeds, due to the simple nature of the drainages present and the absence of any aquatic
features that would be under the jurisdiction of one agency but not the other. A total of 0.12 acres
of waters of the state under the jurisdiction of the RWQCB are also present on the Project site.
5.4.3 CDFG 1602 Streambed Alteration Agreement
As a result of the fact that Little Encinas Creek exhibits a defined bed, bank, and channel, this
drainage feature is subject to the CDFW's permitting authority under Section 1600 ci seq. of the
California Fish and Game Code. The proposed project would result in permanent impacts to 0.12
acre (385 linear feet) of state streambeds. No temporary impacts are assessed. A CDFG Section
1602 agreement is required prior to any alteration of a feature that qualifies as state jurisdictional
streambed.

6.0 CONCLUSIONS
PSlob#/50514
May 5, 2016
A total of 0.12 acres of non-wetland waters that are under the jurisdiction of the US ACE, CDFW
and the RWQCB will be impacted by the proposed project.
6.1 U.S. ARMY CORPS OF ENGINEERS PERMIT REQUIREMENTS
Tue proposed project would result in pennanent impacts to 0.13 acre (385 linear feet) non-
wetland waters of the United States. A Nationwide Pennit (NWP) 14 may be issued for the
proposed project if pennanent impacts to waters of the United States are less than 0.50 acre and
300 linear feet. The District Engineer may waive the 300 linear foot requirement if it is
determined that the proposed project complies with all other tenns and conditions of the NWP
and adverse environmental effects are minimal both individually and cwnulatively. The District
Engineer must waive the limitation on stream impacts in writing before the pennittee may
proceed with construction. If the District Engineer does not waive the linear foot requirement for
the proposed project, an individual pennit (W) would be required. Individual Permits require the
USACE to issue a Public Notice, review a full analysis of alternatives, and prepare a NEPA
document. The NWP process does not require the USACE to issue a Public Notice, review a full
analysis of alternatives, or prepare a NEPA document.
6.2 CALIFORNIA DEPARTMENT OF FISH AND GAME PERMIT REQUIREMENTS
A CDFW Streambed Alteration Agreement, under Section 1602 of the California Fish and Game
Code is required. The Streambed Alteration Agreement for the Project will contain terms and
conditions governing the nature of the impacts allowed, and may include restrictions on the
locations, methods, or timing of project activities affecting the stream. In addition, compensatory
mitigation to offset any pennanent losses of streambeds caused by the Project may be required.
The project applicant must submit a Notification of Lake or Streambed Alteration to the CDFW
prior to diverting, obstructing, or altering the jurisdictional drainage of Little Fncinas Creek
6.3 REGIONAL WATER QUALITY CONTROL BOARD PERMIT
REQUIREMENTS
In connection with notification to the USACE under Section 404 of the CWA, pursuant to 33
CFR Part 330, a written request for Section 401 water quality certification must be submitted to
the RWQCB to ensure that no degradation of water quality would result from the proposed
project. The RWQCB Section 401 certification must be issued prior to commencement of any
project activity that might affect water quality. RWQCB jurisdictional impact areas are the same
as those descnbed for the USACE.

Subject: Geotechnical and Environmental Review in Support of SB 330 Streamline
Application, Holly Springs-Encinas Creek 11, Carlsbad, San Diego County,
California
Dear Mr. Cablay:
\n accordance with your request and authorization, GeoSoils, lnc. (GSI) is presenting the
results of our geotechnical and environmental review regarding the possible location of the
site in a potential earthquake fault zone or hazardous waste site. The scope of our services
has included a review of the referenced documents in the Appendix, analysis of data, and
preparation of this summary letter.
To evaluate if the site is in an earthquake fault zone, GS! reviewed "Earthquake fault zones,
a guide for government agencies, property owners/developers, and geoscience
practitioners for assessing fault rupture hazards in California," by the California Geological
Survey (2018 [see references]). The nearest active fault lies offshore, and is part of the
Newport~lnglewood -Rose Canyon fault zone, and the site is not in an Alquist-Priolo
Earthquake Fault Zone. To evaluate if the site is in a local fault zone, GSI reviewed
"Geotechnical hazards analysis and mapping study, Fault location and seismically induced
ground shaking maps" dated November, 1992, by the City of Carlsbad. While the region
includes bedrock (ancient) faults, no Holocene (active) faults are know to exist in the Holly
Springs-Encinas \I area.
To evaluate if the site is in a hazardous wast site, GSl utilized EnviroStor, maintained at the
California Department of Toxic Substances Control's (DTSC) website. EnviroStor is the
(DTSC) data management system for tracking cleanup, permitting, enforcement and
investigation efforts at hazardous waste facilities and sites with known contamination or
sites where there may be reasons to investigate further. DTSC maintains the website,
which provides information pertaining to hazardous waste generators, including types of
waste generated, volumes, and dates. The subject site is not shown as underlain by
hazardous waste.
Geo Tracker is the Regional Water Quality and Control Boards' data management system
for sites that impact, or have the potential to impact, water quality in California, with
emphasis on groundwater. Geo Tracker contains records for sites that require cleanup,
such as Leaking Underground Storage Tank (LUST) Sites, Department of Defense Sites,
and Cleanup Program Sites. One site was mapped on the property margin, in the
intersection of College Blvd and Canon Rd. This site (id T0607377031 ), was opened on
August15, 2002, and closed on February 15, 2005. Based on the case status, it is not
anticipated to affect the site.
CONCLUSIONS
Based on our engineering and geologic analyses, the site is not in a known active
earthquake fault zone, nor located in a hazardous waste site.
LIMITATIONS
The materials encountered on the project site and utilized for our analysis are believed
representative of the area. Inasmuch as our study is based upon our review and
engineering analyses and laboratory data, the conclusions and recommendations are
professional opinions. These opinions have been derived in accordance with current
standards of practice, and no warranty, either express or implied, is given. Standards of
practice are subject to change with time. GSl assumes no responsibility or liability for work
or testing performed by others, or their inaction. Use of this report constitutes an
agreement and consent by the user to all the limitations outlined above, notwithstanding
any other agreements that may be in place. In addition, this report may be subject to
review by the controlling authorities. Thus, this report brings to completion our scope of
services for this portion of the project.

CULTURAL INFORMATION
A report on a Cultural Rcsoun.:es Records Search (I .Si\, October 2016) has been conducted for the
property. This included an archaeological and historiciil records search and the examination of historic
maps and aerial photographs.
Seventeen ( 17) documented archaeological investigations have taken place within a quarter-mile radius of
the project area, live of which involve the pro_iect location. The investigations indicate that prehistoric
sites arc in proximity to the project area. The following inventories were also examined: National
Register of Historic Places, California Regi~ter of Historical Resources, California! listorical I .and marks,
California I !istoric Properties Directory. and California Points of Historical Interest within a half-mile
radius.
Based on the results of the records search, no cultural resources !rnve been previously recorded within the
APE for the ACOE boundary. One cultural resource, P--37-017303, which consists of prehistoric lithics,
shell, and milling features, is located approximately 100 feet cast of the APE. Testing and surfm;e
collection at the site recovered 14 artifacts associated with the bedrock milling features, but no subsurface
deposit was observed and the site \Vas recommended as not eligible for listing on the 1\ational Register or
Historic Places.
Results: 1\cgative.
Please see the anached Cultural Resources Survey Results report (I.SA, 2016). No map of the location of

Subject: Cultural Resources Records Search Results for the Encinas Creek Apartments Project,
Carlsbad, California (LSA Project No. SBD1601)
Dear Mr. Cablay:
LSA completed a cultural resources records search for a 0.12-acre Area of Potential Effects (APE)
within the jurisdiction of the United States Army Corps of Engineers (Corps) near the Encinas Creek
Apartments Project (Project) on September 21, 2016 (Figure 1). The records search results were
received from the South Coastal Information Center (SCIC) at San Diego State University on October
18, 2016. The records search included an examination of all previous surveys, archaeological sites,
subsurface investigations, and all surveys and investigations that have been completed within a half-
mile radius of the project area. The following inventories were also examined: National Register of
Historic Places, California Register of Historical Resources, California Historical Landmarks, California
Historic Properties Directory, and California Points of Historical Interest within a half-mile radius.
Results of the records search indicate that at least 24 previous cultural resources studies have
occurred within a half-mile of the project APE (Table 1). These studies include historic building
evaluations, data recovery and testing programs, and results of surveys and archaeological
monitoring during construction. Seven previous studies include portions of the APE, the most recent
of which was completed in 2003.
Thirty-two cultural resources have been recorded within a half-mile of the project APE, none of
which are located within the APE (Table 2). Site P-37-017303 is located approximately 100 feet
northeast of the APE, and consists of a prehistoric lithic and shell scatter with associated bedrock
milling features (Stropes 2016). The oth~r previously recorded resources include mainly prehistoric
sites with bedrock milling features, and lithic and shell scatters. One historic-age resource, P-37-
024329, is the Robertson Ranch farm house that was constructed in the late 1890s (Pierson 2001).

DISCUSSION
Based on the results of the records search, no cultural resources have been previously recorded
within the APE for the ACOE boundary. One cultural resource, P-37-017303, which consists of
prehistoric lit hies, shell, and milling features, is located approximately 100 feet east of the APE.
Testing and surface collection at the site recovered 14 artifacts associated with the bedrock milling
features, but no subsurface deposit was observed and the site was recommended as not eligible for
listing on the National Register of Historic Places (Stropes 2016).
Sincerely,
