Major components of the proposed project include sidewalk improvements, bridge and barrier rail improvements, and constructing a new pedestrian bridge across Agua Hedionda Creek along the eastern edge of ECR.1 Under contract with the City, LSA conducted a pre-construction general biological resources assessment, a fall/winter season nighttime bat survey, and a jurisdictional delineation to identify the limits of aquatic resources potentially subject to the jurisdiction of the United States Army Corps of Engineers (Corps), the Regional Water Quality Control Board (RWQCB), the California Department of Fish and Wildlife (CDFW), and the California Coastal Commission (CCC). LSA surveyed an approximately 3.46-acre Biological Study Area (BSA). LSA conducted the original general biological resources assessment on December 8, 2014, and a follow-up site visit on March 9, 2018, to update vegetation mapping and note any changes within the BSA. LSA conducted the original jurisdictional delineation fieldwork on December 10, 2014, and follow-up site visits on April 30, 2018, and April 22, 2019, to assess the BSA for any changes to aquatic resources. LSA conducted the fall/winter season nighttime bat survey on November 11, 2015. LSA did not perform an updated bat survey, as much of the BSA is highly disturbed, and an updated bat survey is not likely to yield different findings or data in support of additional mitigation measures. The entire BSA is within the City Habitat Management Plan (HMP) Area. The western half of the BSA (west of the eastern edge of the ECR right-of-way) is within the Coastal Zone and within an existing Hardline Conservation Area at the northwestern corner of Local Facilities Management Zone 24. The western half of the BSA appears to be within the Core 4 Focused Planning Area (FPA}, while the eastern half of the BSA appears to be within Linkage Area B, which connects to the Core 2 and Core 3 FPAs. Yuma myotis {Myotis yumanensis, CDFW Special Animal), a special-status bat species, was observed during the fall/winter season nighttime bat survey and San Diego marsh-elder (Iva hayesiana, California Rare Plant Rank [CRPR] 2B.2), a special-status plant species, was observed during the general biological resources assessment. An additional six special-status wildlife species have a moderate or higher potential to occur within the BSA based on the presence of suitable habitat; however, none was observed during the biological surveys. These species are monarch butterfly (Danaus plexippus), coastal California gnatcatcher (Pofiopti/o ca{ifornica ca/ifornica), least Bell's vireo (Vireo be/Iii pusilfus), western red bat (Lasiurus blossevillii), hoary bat (Lasiurus cinereus), and western yellow bat (Lasiurus xanthinus) Although special-status vegetation communities (e.g., riparian scrub, freshwater marsh, coastal sage scrub, open water, unvegetated stream channel, and nonnative grassland) as well as unregulated Although the section of ECR within the project site is oriented in a northwest to southeast direction, ECR typically runs north to south, so for the purposes of simplification and clarification, all directions have been changed to be consistent with a north-south orientation for ECR.

Due to the small amount of permanent impacts to nonnative grassland, the City will achieve the HM P's mitigation requirement by planting native grassland or other appropriate native plant species on site where ornamental vegetation is currently present. Permanent impacts to ornamental and developed land do not require mitigation. The project is not expected to result in permanent impacts to areas subject to regulation by the Corps, the RWQCB, the CDFW, or the CCC. However, 130 square feet of temporary impacts to these areas will require acquisition of permits from the Corps, the RWQCB, the CDFW, and the CCC. Because these impacts will be temporary and low-intensity (associated with the placement of scaffolding for sidewalk overhang construction on top of vegetation/ground) mitigation is not expected to be required. Implementation of the resource avoidance and minimization measures listed in Section 6.5 will contribute to the minimization of impacts to special-status species and habitat, nesting birds, and aquatic resources.

Major components of the proposed project include sidewalk improvements, bridge and barrier rail improvements, and constructing a new pedestrian bridge across Agua Hedionda Creek along the eastern edge of ECR, within the public right-of-way. These major components are described in further detail below. 2.1.1 Sidewalk Improvements The project proposes construction of a new concrete cantilever slab on top of the existing cantilever slab, to widen the existing western sidewalk from 4 feet to 6 feet. The existing pedestrian hand railing would be relocated to the new sidewalk edge and new barriers would be installed to replace the existing obsolete bridge railings. The sidewalk along the eastern side of ECR is discontinuous for 2S0 feet between Cannon Road and the southern end of the bridge. To complete this missing section of sidewalk, a separate pedestrian bridge is proposed adjacent to the eastern side of the bridge. Details regarding this new pedestrian bridge are discussed below. 2.1.2 Bridge and Barrier/Rail Improvements Existing bridge barriers are damaged in some locations and are obsolete, as they do not meet current Federal Highway Administration (FHWA) crash standards. Concrete and steel barriers along both edges of the bridge deck will be removed and new standard bridge barriers will be installed. New rails will most likely be see-through steel railings. Additionally, the new eastern bridge railing requires impact protection to meet current crash standards. This will likely be in the form of a compact crash-absorbing barrier assembly. The new bridge barrier along the western edge of the bridge deck will be offset several feet from its original alignment, necessitating reconstruction of the approaching metal beam guard rail. This guard rail may also be replaced with a crash barrier, similar to the eastern barrier railing approach. The outward alignment of the barrier will result in the widening of the southbound bicycle lane. According to inspectiOh reports, bridge deck cracking has become worse with time, and cracks are currently present at all four abutment walls at the ends of the deck slabs. To mitigate this existing microcracking, prevent water intrusion, and reduce corrosion rates, a clear Methacrylate sealant will be poured over the entire riding surface of the concrete bridge deck.

The pedestrian bridge would be a prefabricated steel truss bridge, 8 feet wide and 120 feet long, connecting the sidewalk along ECR to the sidewalk at the Cannon Road intersection. The pedestrian bridge will be constructed on new concrete abutments aligned with the existing ECR bridge abutments, which will be supported on deep micro pile foundations. The vertical profile of the proposed steel truss pedestrian bridge would be relatively flat with the deck approximately 18 inches higher than the top of the existing ECR bridge to achieve positive freeboard clearance from flows within Agua Hedionda Creek during a 100-year storm event. Additional right-of-way will be obtained along the eastern edge of the project to accommodate this new pedestrian bridge. 2.1.4 Utility Relocation Numerous overhead utilities along the eastern edge of the bridge must be relocated to accommodate the proposed project. Other utilities in the vicinity consist of a large underground water main, conduits mounted to the edge of the ECR bridge deck, and two fuel lines and one gas line underground along the proposed alignment of the pedestrian bridge. Utilities attached to the eastern edge of the ECR Bridge deck would be protected in place. Affected utilities will either be abandoned or relocated to the new pedestrian bridge. Construction of the new pedestrian bridge abutments is expected to occur from the creek bed and from the parkways above. A portion of the existing brick soundwall behind the southeastern sidewalk will be demolished to allow for the installation of the new pedestrian bridge. The soundwall would be reconstructed and realigned inside the property line of the adjacent residences. Access to the creek bed is anticipated either from the northeastern embankment or an access road from the private driveway several hundred feet upstream. A private gated road and lot adjacent to the northeastern embankment may be considered as a contractor staging area. After construction of the bridge improvements, sidewalks, curbs, and gutters approaching the bridge will be rebuilt. The existing 5-foot-wide sidewalk along the eastern side of ECR, east of the bridge, may also require widening. The temporary project construction footprint will extend beyond the current right-of-way along both sides of the bridge. San Diego Gas & Electric will be installing a 5-inch electrical conduit duct bank within the new pedestrian bridge. Excavation will be required on both sides of the existing bridge structure for connection to existing conduit. Once this work is completed, the two overhead electric distribution poles and associated hardware will be removed. During project construction, several closures of varying durations are anticipated. Long-term shoulder and/or outside lane closures are anticipated during barrier rail replacement operations. Short-term lane closures are anticipated during concrete placement operations. Overnight closure of the entire bridge is required for the deck overlay. At least one bus stop and one driveway are within the project limits and may be affected by these project-related closures.

Specifically, the BSA is in the Agua Hedionda Land Grant of the United States Geological Survey {USGS) San Luis Rey, California 7.5-minute topographic quadrangle map. The BSA contains a section of Agua Hedionda Creek that supports various plant and wildlife species. Due to surrounding residential development, the eastern section of the BSA (east of ECR) is dominated by ornamental vegetation. Native vegetation communities, such as riparian scrub, freshwater marsh, and coastal sage scrub are present at the western section of the BSA (west of ECR). Photographs of the BSA are included as Appendix A. The BSA is within the South Coast subregion of the Southwestern California region of the California Floristic Province and within the Carlsbad Hydrologic Unit {Carlsbad Watershed). The entire BSA is within the HMP Plan Area. The western half of the BSA (west of the eastern edge of the ECR right-of-way) is within the Coastal Zone and within an existing Hard line Conservation Area at the northwestern corner of Local Facilities Management Zone 24. The western half of the BSA appears to be within the Core 4 FPA, while the eastern half of the BSA appears to be within linkage Area B, which connects to the Core 2 and Core 3 FPAs.

The CNDDB contains records of reported occurrences of Federal-and/or State-listed species, proposed endangered or threatened species, California Species of Special Concern (SSC), or otherwise special-status species or habitats that may occur within or in the vicinity of the BSA. Additionally, LSA reviewed the HMP to identify covered species with potential to occur in the BSA. 3.2 GENERAL BIOLOGICAL RESOURCES ASSESSMENT LSA Senior Biologist Jaime Morales and LSA Biologist Scott Batchelder conducted a general biological resources assessment on December 8, 2014. The assessment included the following elements: • Mapping of habitat types; • A directed search for special-status plant and animal species with potential to occur within the BSA; • A general inventory of plant and wildlife species; • Evaluation of suitability of habitat for special-status resources identified during the literature search; • Preliminary identification of areas that may be considered wetland or nonwetland waters of the U.S., stream beds as defined by the Corps and the CDFW, and wetlands as defined by the CCC; and • Notes on other pertinent features or conditions of the site and adjacent lands. LSA recorded a list of all plant species observed within the BSA (see Appendix B). LSA identified and mapped on an aerial photograph vegetation communities within the BSA. Then, using Geographic Information System (GIS) software, LSA digitized the mapping and calculated the acreages of vegetation communities occurring within the BSA. Vegetation communities were determined in accordance with the categories described in Holland ( 1986) and Oberbauer (2008). Plant nomenclature follows that of The Jepson Manual: Higher Plants of California (Hickman 1993). Special-status plant species with a potential to occur within the BSA are described in Section 4.4. All wildlife observed and wildlife sign detected, including tracks, scat, carcasses, burrows, excavations, and vocalizations, were recorded and are included as Appendix C. Notes were made on the general habitat types, species observed, and the conditions of the site. Special-status wildlife species with a potential to occur within the BSA are described in Section 4.4. Mr. Morales conducted a site visit on March 9, 2018, to update the vegetation map due to changes in the project footprint.

LSA prepared a field map of the area to be surveyed using a 2014 aerial photograph base at a scale of 1 inch= 56.25 feet. The study area was surveyed on foot and all areas of potential jurisdiction were evaluated according to Corps, CDFW, and CCC criteria. Data were collected and recorded using a global positioning system (GPS) unit with sub-meter accuracy and directly on the field map, particularly where GPS reception was limited due to dense tree canopies. LSA evaluated areas supporting hydrology or species of plant life potentially indicative of wetlands according to routine wetland delineation procedures described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (Regional Supplement) (Corps 2008). Representative sample points were selected and examined in the field in those areas where wetland jurisdiction was in question or needed to be confirmed. At each sample point, the dominant and subdominant plant species and their wetland indicator statuses were identified (National Wetland Plant List 2014). A small sample pit {approximately 12-20 inches deep) was dug at each point to examine soil characteristics and composition. Soil matrix colors were classified according to the Munsell Soil Color Charts (Munsell Color 2010). Hydrological conditions, including any surface inundation, saturated soils, groundwater levels, and/or other wetland hydrology indicators, were recorded. General site characteristics were also noted. Standard data forms were completed for each sample point. The results of the jurisdictional delineation are presented in a separate report titled Jurisdictional Delineation Report: El Camino Real at Cannon Road Intersection Improvements Project, City of Carlsbad, San Diego County, California prepared by LSA (Revised December 2019). A copy of that report is included as Appendix D of this report. Mr. Morales conducted follow-up site visits on April 30, 2018, and April 22, 2019, to assess the BSA for any changes to aquatic resources. No significant changes to the limits or classifications of aquatic resources were observed and the findings of the jurisdictional delineation report remain unchanged. 3.4 FALL/WINTER SEASON NIGHTTIME BAT SURVEY LSA Senior Biologist Jill Carpenter and LSA Biologist Lonnie Rodriguez perlormed a fall/winter season nighttime bat survey at the bridge on the evening of November 11, 2015. Prior to the emergence period and exit count portion of the survey, the crevices between the concrete box beams were examined for the presence of day-roosting bats with a high-intensity spotlight, and the approximate numbers, distribution, and species of bats observed were marked on a hand-drawn map. The exit count portion of the survey was subsequently initiated one-half hour before sunset and continued until one hour after sunset. An observer was positioned on each side of the bridge at a vantage point that would optimize visibility of any bats that may exit or enter the bridge in order to obtain an estimate of the number of day-roosting bats present, and to correlate the acoustic data recorded with visual observations. Numbers of bats exiting or entering the bridge were recorded using tally counters. Observers remained in position counting bats until one hour after sunset. Following completion of the emergence period, the biologists performed a second spotlight examination of the crevices between the concrete box beams to determine how many, if any, bats remained in the roost crevices. For the remaining hour of the survey period, the biologists P:\HCR1905 • £CR at Cannon Rd lmprmi@m@nt<\BTR\ECR !l<idge BTR_Rev_June2020_Cle•n.docx (06/17/20) 8 BIOLQG,c>L R<SOURCB TEC"""" Reeosr Revis,o JuN, 2020 El CAMINO RfAL .r [ANNON RoAO INTERS,CTIGN IMPAO'""'<NTS PROJHT c,n OF CAalSOAO, c.,,,o,NIA LSA assessed the level of night-roosting activity beneath the bridge by observing and documenting any bat activity in the vicinity of the structure using night vision equipment. Three Pettersson D240X and one Wildlife Acoustics EchoMeter 3+ ultrasound detectors were used in time expansion mode to collect acoustic data during the entirety of each nighttime survey. These data, consisting of full-spectrum sonograms of echolocation calls, were subsequently analyzed using SonoBat 2.9 acoustic analysis software. Species identifications were made by comparing call recordings with a library of "voucher" calls from known hand-released bats. Some limitations are inherent in acoustic monitoring and in the analysis of acoustic data and include (but are not limited to) human bias and past experience in data interpretation, as well as the fact that some species are not equally detectable or may not be recorded at all. For example, some bats (e.g., Mexican free- tailed bats [Tadarida brasi/iensis]) emit loud low-frequency echolocati~n calls that can be recorded from great distances and will be overrepresented in the data, while "whispering" bats (e.g., Townsend's big-eared bats [Corynarhinus townsendi1l) emit faint calls that may not be recorded at all. In addition, not all call sequences are identifiable. Different bat species may use similar types of echolocation calls, or the same species may use different types of echolocation calls based on the perceptual task and the immediate environment or habitat. In addition, not all bats recorded will be those exiting or entering the bridge in question. Some are foraging bats en route to or from other structures. It is important, therefore, to have observers on site in order to correlate calls with visual observations. The results of the nighttime bat survey are presented in a separate memorandum prepared by LSA (January 2016). A copy of that memorandum is included as Appendix E of this report. LSA did not perform an updated bat survey, as much of the BSA is highly disturbed, and an updated bat survey is not likely to yield different findings or data in support of additional mitigation measures. p ,\HCR1905 -ECR at Cannon Rd ln>provomonts\BTR\ECR Bridge 8TR_Rev_Juno2020_Clean docx 106/17 /201 9 a,o,oGICA< RESOURC" TecHN,CAC REPORT REVISEO JuN, 2020 E, CAMINO RHl AT CANNON RoAO INHR5,CTIOI< IMeaOVEME~TS P•OJ<CT (,n OF (ARlSUD, CAUFOR~IA LSA SECTION 4.0: RESULTS AND DISCUSSION 4.1 VEGETATION COMMUNITIES The BSA supports vegetation communities totaling 3.46 acres.

Present Species was detected within or near the BSA during project surveys. Each special-status plant and wildlife species with the potential to be present in the project vicinity is discussed in Appendix F. 4.4.1 Special-Status Plants The results of the records search indicate the potential occurrence of seven species listed as Threatened or Endangered at the Federal and/or State level (hereafter referred to as listed species) and 37 other special-status plant species. Based on the results of the biological resources assessment, of these 44 special-status plant species, only one species {San Diego marsh-elder) was determined to have a moderate or higher potential of occurring within the BSA due to the presence of suitable habitat (see 4.4.1.1, below). San Diego marsh-elder was observed in the BSA during the biological resources assessment. The remaining 43 special-status plant species identified by the literature review have a low potential to occur within the BSA due to the presence of only marginally-suitable habitat, or are not expected to occur within the BSA due to the absence of suitable habitat. 4.4.1.1: San Diego Marsh-Elder (Iva hayesianaJ CRPR 28.2 A few scattered individuals of this species were observed west of ECR on the banks of Agua Hedionda Creek under the canopy of the riparian scrub. 4.4.2 Special-Status Wildlife The results of the records search indicate the potential occurrence of four listed species and 11 other special-status wildlife species.

The results of the records search indicate the potential occurrence of 12 Narrow Endemic species. However, based on the results of the biological resources assessment, none of these species is expected to occur within the BSA due to the absence of suitable habitat. No Narrow Endemic species were observed in the BSA during the biological resources assessment. 4.5 U.S. FISH AND WILDLIFE SERVICE CRITICAL HABITAT AREAS Critical habitat for thread-leaved brodiaea (Brodiaea fi/ifolia), coastal California gnatcatcher, San Diego thorn-mint (Acanthomintha ilicifofia), and southwestern willow flycatcher (Empidonax trail/ii extimus) is approximately 0.8 mile southeast, 1.5 miles south, 2.1 miles east, and 2.5 miles east of the BSA, respectively. 4.6 WILDLIFE CORRIDORS The northern half of the BSA serves as a migration corridor for wildlife species. The BSA, via Agua Hedionda Creek, connects to undeveloped land to the west and Los Monos Canyon to the east, which is also undeveloped. The eastern half of the BSA is within HMP linkage B, which connects the Core 4 FPA to the Core 2 and 3 FPAs. 4.7 AQUATIC RESOURCES Calavera Creek and Agua Hedionda Creek converge east of the BSA. Agua Hedionda Creek continues westward and conveys flows through the BSA. The creek conveys flows within a natural channel and underneath the ECR Bridge. Water within the creek may also receive additional water from irrigation runoff from the surrounding development and associated ornamental vegetation. Additionally, hydrophytic vegetation and hydric soils occur at the southeastern corner of the BSA. This area does not receive flows from Agua Hedionda Creek; rather, it is at a similar elevation to the creek, and the hydrophytic vegetation is likely supported by a high water table. A vegetated berm and unpaved access road separate this area from Agua Hedionda Creek. LSA presumes that a hydraulic connection exists between Agua Hedionda Creek and the area dominated by hydrophytic vegetation that is outside of the OHWM. Agua Hedionda Creek is a tributary to the Agua Hedionda Lagoon, and ultimately the Pacific Ocean (a Traditional Navigable Water (TNW] of the U.S.). Because of the direct connection with the Pacific Ocean, this feature is subject to Corps jurisdiction to the Ordinary High Water Mark (OHWM) and adjacent wetlands. The entire area mapped as wetlands meets all three criteria for wetland waters of the U.S. as defined by the Corps: wetland hydrology, hydric soils, and dominance of hydrophytic plant species. However, based on recent guidance from Corps staff, areas within the OHWM that P:\HCR1905 • ECR at Cannon Rd lmpro,emenls\BTR\ECR Bridgo BTR_Ros_JuneW20_Cleon.doe< (06/17 /20) 16 C BIOlDGICAL R,scu,c,s T,cHNICAL R,eoRT R,v SEO JuN, 2020 El CAMINO REAL AT CANNON ROAO IN-"S,CTION IMPaov,MENTS P>e>JECT CITY Of CMlSOAo, CAL1FO,N1A LSA meet all three criteria for wetland waters of the U.S. are mapped as nonwetland waters of the U.S. Because the area at the southwestern corner of the BSA displays a hydraulic connection (i.e., hydrology) to the creek, prevalence of hydrophytic vegetation, and presence of hydric soils, LSA considers this area to be wetland waters of the U.S. that are adjacent to Agua Hedionda Creek. Streambed and banks, including riparian scrub vegetation associated with this drainage feature, are subject to CDFW jurisdiction. Because the western half of the BSA (west of the eastern edge of the ECR right-of-way) is within the Coastal Zone, areas west of the eastern edge of the ECR right-of-way that are subject to CDFW jurisdiction are also considered CCC Wetlands. Functions and values for the creek were determined to have a moderate to high significance in terms of resources. Figure 3 depicts the location of this feature and extent of resource agency jurisdiction. Further information about the aquatic resources present within the BSA is presented in a report titled Jurisdictional Delineation Report: El Camino Real at Connon Rood Intersection Improvements Project, City of Carlsbad, San Diego County, California prepared by LSA (2019).

Construction of this project would result in permanent loss of a small amount of nonnative grassland, ornamental vegetation, and developed land. 5.1.1 Permanent Impacts Permanent loss involves long-term impacts associated with construction of the pedestrian bridge and sidewalk overhang abutments. 5.1.2 Temporary Impacts Temporary disturbance includes grading and compaction at four areas associated with each of the four pedestrian bridge/sidewalk overhang abutments, followed by efforts associated with subsequent revegetation (e.g., site preparation and hydroseeding). Minor temporary disturbance will also occur due to construction crew pedestrian access through vegetation and placement of scaffolding for sidewalk overhang construction on top of vegetation/ground. 5.1.3 Direct Impacts Direct impacts to vegetation communities will result from temporary and/or permanent clearing of vegetation or temporary physical disturbance of vegetation (construction crew pedestrian access and placement of equipment materials). It is anticipated that wildlife within the immediate vicinity of any active work areas will be displaced for the duration of the activity. 5.1.4 Indirect Impacts Indirect impacts to adjacent areas may result from noise and dust generated by construction-related activities, which has the potential to disturb nearby wildlife and, in the case of dust, vegetation. Additionally, if construction is performed at night, lighting has the potential to indirectly affect wildlife. 5.2 VEGETATION COMMUNITIES Figure 4 displays the anticipated impacts to vegetation communities within the BSA on an aerial photograph.

No other special- status plant species were observed during the biological resources assessment. Due to the absence of suitable habitat for the other special-status plant species and due to the absence of conspicuous perennial special-status plant species other than San Diego marsh-elder, there is a low potential for impacts to special-status plant species as a result of project-related activities. Additionally, impacts to San Diego marsh-elder are not anticipated because project-related impacts will mostly occur in upland areas and temporary impacts to riparian scrub will be limited to construction crew access by foot. Implementation of avoidance measures provided in Section 6.S will further reduce the potential for impacts to San Diego marsh-elder. 5.4 SPECIAL-STATUS WILDLIFE SPECIES 5.4.1 Special-Status Invertebrate Species Although no special-status invertebrate species were observed during the biological resources assessment, there is a moderate potential for monarch butterfly to roost within the eucalyptus trees present within the BSA. Monarch butterfly wintering sites are considered a special-status resource by the CDFW. Implementation of avoidance measures provided in Section 6.5 will reduce the potential for impacts to monarch butterfly. 5.4.2 Special-Status Avian Species and Nesting Birds Although no special-status avian species were observed during the biological resources assessment, there is a moderate potential for coastal California gnatcatcher (FT, SSC, HMP Covered) and least Bell's vireo {FE, SE, HMP Covered) to occur within the coastal sage scrub and riparian scrub in the BSA, respectively. Impacts to coastal sage scrub and riparian scrub have the potential to affect these species directly through the loss of suitable foraging and nesting habitat or indirectly through impacts associated with noise and dust during construction. Additionally, if project-related activities are conducted during the bird breeding season (January 15 through September 15), they may cause both temporary and permanent impacts to foraging and/or nesting habitat for avian species that are P.\HCR19'05 -ECR ot C,nnon Rd lmprovoments\BTR\ECR Bridgo BTR_Rov_Juno2020_Clean.doc, 106/17 /201 21 , 6IOCOGICAL R,sou•c" THHNICAt REPOST Re,,;rn JuN, 2020 Et CAMINO REAL AT CANNON RDAD INTERSECTION IMPAO,EMENTS PROJECr c,n o, CASLSOAO, CWFORNIA LSA not considered special-status, but are covered under the Migratory Bird Treaty Act (MBTA).

Although the following foliage-roosting bat species were not observed or detected during the biological resources assessment or the bat survey, there is a moderate potential for them to occur within the trees in the BSA: western red bat (SSC), hoary bat (SA), and western yellow bat (SSC). Activities performed close to the bridge crevices have the potential to affect Yuma myotis individuals temporarily, especially if activities are performed during the bat maternity season (April 1 through August 31). Clearing/disturbance of trees have the potential to affect the foliage-roosting species directly through the loss of suitable roosting habitat and all bat species could be indirectly affected by impacts associated with activities that generate high amounts of vibration, noise, or possible night lighting. Implementation of avoidance measures provided in Section 6.5 will reduce the potential for impacts to special-status bat species. 5.5 HMP COVERED SPECIES Coastal California gnatcatcher and least Bell's vireo are the only HMP Covered Species with a • moderate or higher potential to occur within the BSA. Impacts to coastal sage scrub and riparian scrub-coastal California gnatcatcher and least Bell's vireo habitat, respectively-have the potential to affect these species directly through the temporary loss of suitable habitat and indirectly through impacts associated with noise and dust during construction. Implementation of avoidance measures provided in Section 6.5 will reduce the potential for impacts to coastal California gnatcatcher and least Bell's vireo. 5.6 NARROW ENDEMIC SPECIES The results of the literature and database records search indicate the potential occurrence of 12 Narrow Endemic species. However, based on the results of the biological resources assessment, none of these species is expected to occur within the BSA due to the absence of suitable habitat. Furthermore, no Narrow Endemic species were observed in the BSA during the biological resources assessment. The project is not expected to affect any Narrow Endemic species. 5.7 U.S. FISH AND WILDLIFE SERVICE CRITICAL HABITAT AREAS Critical habitat for thread-leaved brodiaea, coastal California gnatcatcher, San Diego thorn-mint, and southwestern willow flycatcher is approximately 0.8 mile southeast, 1.5 miles south, 2.1 miles east, and 2.5 miles east of the BSA, respectively. Due to the distances from the BSA, no designated critical habitat will be affected by the proposed project activities. 5.8 WILDLIFE MOVEMENT CORRIDORS The northern half of the BSA serves as a migration corridor for wildlife species, as wildlife can move along the banks and within Agua Hedionda Creek under the ECR Bridge.

Temporary impacts to riparian scrub and freshwater marsh will result from the placement of scaffolding for sidewalk overhang construction; however, because these activities will be of short duration and low-impact, vegetation is expected to grow back. Temporary impacts to unvegetated stream channel and open water will result from the placement of scaffolding for sidewalk overhang construction. These areas are unvegetated and will require no revegetation. Temporary impacts to ornamental and developed land do not require revegetation; however, non- invasive replacement ornamental trees will be planted in affected ornamental areas. 6.1.2 Permanent Impacts Table J displays the appropriate mitigation (as described in the HMP) and anticipated mitigation totals for permanent impacts to vegetation communities.

No other special-status plant species were observed during the biological resources assessment. Due to the absence of suitable habitat for the other special-status plant species and due to the absence of conspicuous perennial special-status plant species other than San Diego marsh-elder, there is a low potential for impacts to special-status plant species as a result of project-related activities. To further reduce the potential for impacts to San Diego marsh-elder, a biologist should flag individuals of this species near work areas or access Pc\HCRI905 -ECR ot C.nnon Rd lmprnvements\8TR\ECR Bridg@ BTR_Rev_June2020_Cleon docx (06/17 /20) 25 B10L0~1CAL RE>OU,CES TECHNICAL REPO•T REV1HO JUNE 2020 h c, .. ,uo REAL AT CANNON ROAD INTERsEC.,ON IMPROVEMeN•S P•oJECJ en, OF CARLSBAD, c,11,oRNIA LSA paths for avoidance. Additionally, pertinent information about this species (e.g., description, location, and reason for avoidance) should be included in an environmental awareness training program to be provided to all project personnel. Because no impacts are expected to occur to special-status plant species, no mitigation for these species is required. 6.2.2 Special-Status Invertebrate Species Although there is a moderate potential for monarch butterfly to roost within the eucalyptus trees present within the BSA, impacts to this species' roosting sit.es will be avoided to the greatest extent practicable by having a biologist perform a presence/absence survey for monarch butterfly prior to disturbance/removal of eucalyptus trees. The biologist will survey the tree(s) to be affected and an appropriately-sized surrounding buffer. If any Monarch butterfly roosting sites are identified, tree disturbance/removal will be prohibited until roosting is no longer observed. Because no impacts are expected to occur to monarch butterfly or any other special-status invertebrate species, no mitigation for these species is required. 6.2.3 Special-Status Avian Species and Nesting Migratory Birds Impacts to coastal California gnatcatcher, least Bell's vireo, and nesting birds protected under the MBTA will be avoided to the greatest extent practicable either by conducting vegetation disturbance outside of the typical bird breeding season (i.e., between September 16 and January 14), or by having a biologist perform a nesting bird survey within the proposed construction area and a 300- foot buffer no more than 72 hours prior to vegetation disturbance during the bird breeding season. lfthe planned vegetation disturbance does not occur within 72 hours of the nesting bird survey, then the area would be resurveyed. If nesting birds are found, then the qualified biologist should establish an adequate buffer zone (on a species-by-species, case-by-case basis) in which construction activities are prohibited until the nest is no longer active. The size of the buffer zone is determined by the biological monitor based on the amount, intensity, and duration of construction, and can be altered based on site conditions. If appropriate, as determined by the biological monitor, additional monitoring of the nesting birds may be conducted during construction to ensure that nesting activities are not disrupted. If any active coastal California gnatcatcher or least Bell's vireo nests are identified, then the project biologist will consult with the USFWS for direction on appropriate buffer zone radius for avoidance. Because no impacts are expected to occur to special- status avian species or nesting migratory birds, no mitigation for these species is required. 6.2.4 Special-Status Bat Species Impacts to special-status bat species will be avoided to the greatest extent practicable by having a bat specialist conduct a survey prior to construction activities to determine the need for humane eviction or other avoidance and minimization measures. Additionally, conducting tree removal or construction activities adjacent to the bridge outside of the bat maternity season (i.e., September 1 through March 31); ensuring that possible night lighting only be used on the portion of the bridge structure actively being worked on and that the lighting be focused on the direct area of work; and ensuring that airspace access to and from the bat roost features is not obstructed except at direct work areas would further reduce the potential for impacts to these species.

The project is not expected to result in impacts to coastal California gnatcatcher or least Bell's vireo because vegetation disturbance is anticipated to take place outside of the bird breeding season. However, in the event that vegetation clearing and grubbing must occur during the bird breeding season, a qualified biologist will perform a nesting bird survey prior to vegetation disturbance to determine if coastal California gnatcatcher, least Bell's vireo, or any other birds or their nests are present. If any active coastal California gnatcatcher or least Bell's vireo nests are identified, then the project biologist will consult with the USFWS for direction on appropriate buffer zone radius for avoidance. Because no impacts are expected to occur to coastal California gnatcatcher or least Bell's vireo, no mitigation for these species is required. 6.2.6 Narrow Endemic Species Due to the absence of suitable habitat, no Narrow Endemic species were observed during the biological resources assessment and none has a moderate or higher potential to occur within the BSA. The project is not expected to affect any Narrow Endemic species; therefore, no mitigation is required for Narrow Endemic species. 6.3 REDUCTION OF IMPACTS TO JURISDICTIONAL RESOURCES Temporary impacts are expected to occur to areas potentially subject to the jurisdiction of resource agencies; therefore, consultation will be required from the Corps, the RWQCB, the CDFW, and the CCC for this project. Permits from these agencies will be required based on staff evaluation of impacts. Because these impacts will be temporary and low-intensity (associated with the placement of scaffolding for sidewalk overhang construction on top of vegetation/ground) mitigation is not expected to be required. 6.4 COMPLIANCE WITH HMP COASTAL ZONE STANDARDS All projects within the Coastal Zone are required to comply with HMP Coastal Zone Standards 7-1 through 7-14 (HMP Section D). Compliance with these standards is described below. • 7-1: Environmentally Sensitive Habitat Areas (ESHA). No ESHAs are present within the BSA. • 7-2: Coastal Sage Scrub. Under this standard, properties containing coastal sage scrub located in the Coastal Zone shall conserve a minimum of 67 percent of the coastal sage scrub and 75 percent of the coastal California gnatcatchers on site. No coastal sage scrub within the Coastal Zone will be affected by project-related activities. Only coastal sage scrub east of ECR (outside of the Coastal Zone) will be temporarily affected by project-related activities. No coastal California gnatcatchers are expected to be affected by project-related activities. • 7-3: Oak Woodland. No oak woodland is present within the BSA. p ,\HCR1905 .

Agua Hedionda Creek is within the BSA. Temporary impacts will result from construction crew pedestrian access and the placement of scaffolding for sidewalk overhang construction within the creek. • 7-5: Ephemeral Drainages and Ephemeral Streams. No ephemeral drainages or ephemeral streams are present within the BSA. • 7-6: Wetlands. CCC wetlands are present within the BSA. Short-term, low-intensity impacts to wetlands will result from the placement of scaffolding for sidewalk overhang construction on top of the vegetation/ground. • 7-7: Wetland Mitigation Requirements. Because wetlands are expected to be temporarily affected by low-intensity activities (placement of scaffolding for sidewalk overhang construction on top of the vegetation/ground), no wetland mitigation is required. • 7-8: No Net Loss of Habitat. No coastal sage scrub within the Coastal Zone will be affected by project-related activities. Only coastal sage scrub east of the ECR right-of-way (outside of the Coastal Zone} will be temporarily affected by project-related activities. • 7-9: Upland Habitat Mitigation Requirements. No coastal sage scrub within the Coastal Zone will be affected by project-related activities. Only coastal sage scrub east of ECR right-of-way (outside of the Coastal Zone) will be temporarily affected by project-related activities. No mitigation is required. • 7-10: Highly Constrained Properties. The proposed project is not constrained by any ESHA. • 7-11: Buffers and Fuel Modification Zones. Because no mitigation is proposed, no buffer is necessary. • 7-12: Grading and Landscaping Requirements. The project will be designed to avoid conducting grading activity during the rainy season (October 1 to April 1); however, it is understood that construction may be extended into the rainy season with the approval of the City engineer and with the implementation of special erosion control measures designed to prohibit discharge of sediments off site. All graded areas shall be revegetated prior to October 1 to reduce erosion potential. • 7-13: City-Owned Lands Adjacent to Macario Canyon and Veterans Memorial Park. These standards are not applicable to this project. • 7-14: Other Parcels-Specific Habitat Protection Standards. These standards are not applicable to this project. 6.5 AVOIDANCE AND MINIMIZATION MEASURES In order to avoid or minimize impacts to existing biological resources, LSA recommends the following measures during project implementation: • A biologist will prepare an Environmental Awareness Training Program to be provided to all project personnel prior to commencement of project-related activities. The program will contain information concerning special-status plant, wildlife, and aquatic resources, including, but not P:\HCR1905 -ECR at cannon Rd lmprovement>\BTR\ECR Bridge BTR_Rev_J~ne2020_0e~n.docx I00/17 /20) 28 BIOLOGIUl Ruoc•c" TErnNICAl REPORt Re,isrn Jo•• 2020 El CAMINO REAL AT CANNON Ro,o INTE.SHTION IMPROVEMENTS P,OJ>CT CITY 0, CARLSOAD, CALIFORNIA LSA limited to, descriptions, locations of suitable habitat, reasons for avoidance, and avoidance and minimization measures. • The contractor will install orange construction fencing (or similar) along the perimeter of the proposed Temporary Impact Areas to demarcate limits of work clearly. A biologist will be present during this activity to direct that impacts to vegetation outside of the proposed Temporary Impact Areas and bird nests (if fence installation occurs between January 15 and September 15) are avoided. • A biologist will flag San Diego marsh-elder individuals near work areas or access paths for avoidance. • A biologist will perform a presence/absence survey for monarch butterfly prior to disturbance/ removal of eucalyptus trees. The biologist will survey the tree(s) to be affected and an appropriately-sized surrounding buffer. If any Monarch butterfly roosting sites are identified, tree disturbance/removal will be prohibited until roosting is no longer observed. • If vegetation disturbance is scheduled to occur during the bird breeding season (between January 15 and September 15), a biologist will perform a nesting bird survey within the proposed construction area and appropriately-sized buffer no more than 72 hours prior to vegetation disturbance. If the planned vegetation disturbance does not occur within 72 hours of the nesting bird survey, then the area will be resurveyed. If nesting birds are found, then the qualified biologist will establish an adequate buffer zone (on a species-by-species, case-by-case basis) in which construction activities would be prohibited until the nest is no longer active. The size of the buffer zone is determined by the biological monitor based on the amount, intensity, and duration of construction, and can be altered based on site conditions. If appropriate, as determined by the biological monitor, additional monitoring of the nesting birds may be conducted during construction to ensure that nesting activities are not disrupted. If any active coastal California gnatcatcher or least Bell's vireo nests are identified, then the project biologist will consult with the USFWS for direction on appropriate buffer zone radius for avoidance. • A bat specialist will conduct a survey prior to construction activities to determine the need for humane eviction or other avoidance and minimization measures. • Tree removal or construction activities adjacent to the bridge will be conducted outside of the bat maternity season {April 1 through August 31) to the greatest extent practicable. • If nighttime work is necessary during construction, then LSA recommends that night lighting only be used on the portion of the bridge structure actively being worked on, that the lighting be focused on the direct area of work, and that airspace access to and from the bat roost features not be obstructed except at direct work areas. • All vehicles, equipment, tools, and supplies will stay within the limits of the Temporary Impact Areas, but no vehicles, equipment, tools, or supplies will be placed within the Agua Hedionda Creek or its associated riparian vegetation. Only the temporary placement of the scaffolding associated with sidewalk overhang construction will be placed on top of vegetation/ground within the creek. • BMP features (e.g., silt fencing, straw wattles, and gravel bags) will be installed where necessary to prevent off-site sedimentation.

The report summarizes the results of fieldwork conducted to identify the limits of potential waters of the United States subject to the jurisdiction of the United States Army Corps of Engineers (Corps) and Regional Water Quality Control Board (RWQCB) pursuant to Sections 404 and 401 of the Federal Clean Water Act (CWA), respectively; streambeds, water bodies, and associated habitat subject to California Department of Fish and Wildlife (CDFW) regulation pursuant to the California Fish and Game Code, and aquatic resources subject to California Coastal Commission (CCC) regulation pursuant to the California Coastal Act. LSA surveyed an approximately 1.8-acre study area located in the City of Carlsbad (City), San Diego County, California (Figure 1). This report has been prepared for the City for purposes of identifying aquatic resource limits for design consideration with the intent of minimizing and avoiding impacts to aquatic resources to the greatest extent feasible, and for submittal to the Corps, CDFW, RWQCB, and CCC as part of their review of applications for permit authorization, if project impacts trigger the need for such permits. This routine wetland and jurisdictional delineation was conducted under contract with the City. The findings and conclusions presented in this report, including the location and extent of aquatic resources subject to regulatory jurisdiction, represent the professional opinion of LSA and should be considered preliminary until verified by representatives of the Corps, CDFW, RWQCB, and CCC. PROPOSED PROJECT The City proposes to improve pedestrian and vehicular operations across the Agua Hedionda Creek Bridge at the intersection of El Camino Real and Cannon Road in the City of Carlsbad, San Diego County, California (Figure 1). Major components of the proposed project include sidewalk improvements, bridge and barrier rail improvements, and constructing a new pedestrian bridge across Agua Hedionda Creek along the eastern edge of El Camino Real. Project-related activities will remain compliant with all State and Federal agencies and permits associated with the project. SITE DESCRIPTION The study area is within the City, at the intersection of El Camino Real and Cannon Road, approximately 2.4 miles east of Interstate 5 along Cannon Road (latitude: 33.149180, longitude: - 117.297093). Specifically, the study area encompasses areas at the northeastern and southeastern corners of the intersection of El Camino Real and Cannon Road, classified by United States Geological Survey (USGS) Unsectioned Land-grant: Agua Hedionda, Township 12 South, and Range 4 West, of the San Luis Rey, California 7.5-minute topographic quadrangle map. The study area contains a section of Agua Hedionda Creek, which supports various plant and wildlife species. The northern section (north of El Camino Real) of the study area is dominated by ornamental vegetation. Native habitats, such as riparian scrub, freshwater marsh, and coastal sage scrub are present in the southern section {south of El Camino Real). The section of the creek underneath the bridge is completely unvegetated.

The study area is within the Carlsbad Hydrologic Unit (HU) (Carlsbad Watershed), which is approximately 210 square miles extending from the headwaters above Lake Wolhford in the east to the Pacific Ocean in the west, and from Vista and Oceanside in the north to Solana Beach, Escondido, and the community of Rancho Santa Fe to the south. The Cities of Carlsbad, San Marcos, and Encinitas are entirely within this watershed. There are numerous important surface hydrologic features within the Carlsbad Watershed, including four unique coastal lagoons, three major creeks, and two large water storage reservoirs. The HU contains four major, roughly parallel hydrologic areas (HAs). Encompassing the study area is the San Marcos (904.2) HA and the Batiquitos hydrologic subarea (HSA) according to the Water Quality Control Plan for the San Diego Basin - Region 9 (State of California 2007). The average annual rainfall for the study area is approximately 11.13 inches.1 REGULATORY BACKGROUND United States Army Corps of Engineers The Corps regulates discharges of dredged or fill material into waters of the United States (WOTUS). These waters include wetland and non-wetland bodies of water that meet specific criteria. Corps regulatory jurisdiction pursuant to Section 404 of the Federal Clean Water Act {CWA) is founded on a connection, or nexus, between the water body in question and interstate commerce. This connection may be direct (through a tributary system linking a stream channel with traditional navigable waters used in interstate or foreign commerce) or may be indirect (through a nexus identified in Corps regulations). For several decades, the operable definition of WOTUS was provided at 33 Code of Federal Regulations (CFR) 328.3, but implementation of this definition has been shaped by the courts and subsequent guidance over the years, most substantially by the 2001 Supreme Court decision in Solid Waste Agency of Northern Cook County v. United States Army Corps of Engineers, No. 99-1178 (SWANCC) and the 2006 Supreme Court decision in the consolidated cases Rapanos v. United States and Corabel/ v. United States (126 5. Ct. 2208), collectively referred to as Rapanos. The Supreme Court concluded that wetlands are WOTUS if they significantly affect the chemical, physical, and biological integrity of other covered waters more readily understood as navigable. Based, in part, on the Rapanos decision, a new rule defining WOTUS was promulgated in the Federal Register on June 29, 2015. Following a series of legal challenges and the current presidential administration's attempt to delay the implementation of this rule, on August 16, 2018, the U.S. District Court for the District of South Carolina enjoined the delay of the WOTUS Rule implementation for failure to comply with the Administrative Procedure Act. This decision made the http://www.idcide.com/weather/ca/carlsbad.htm, January 5, 2015.

However, pursuant to an Executive Order signed on February 28, 2017, "Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the 'Waters of the United States Rule,"' the Corps and EPA had embarked on a two-step process to revise the definition of WOTUS. The first step was to repeal the 2015 WOTUS definition and revert to the operative definition that was shaped by previous regulations and subsequent court decisions. The Federal Register notice that effected this repeal was published on October 22, 2019, with an effective date of December 23, 2019. On February 14, 2019, as the second step of the comprehensive two-step process, the Corps and EPA proposed to interpret WOTUS to encompass: Traditional navigable waters, including the territorial seas; tributaries that contribute perennial or intermittent flow to such waters; certain ditches; certain lakes and ponds; impoundments of otherwise jurisdictional waters; and wetlands adjacent to other jurisdictional waters. The public comment period for the proposed revised definition of WOTUS closed on April 15, 2019, and the agencies are reviewing and considering approximately 620,000 comments they received. If finalized, the revised definition of WOTUS will replace the regulations that the agencies finalized in the October 22, 2019, Federal Register. Given the substantial changes in operable definitions that have occurred and may continue to occur considering the regulatory revisions and potential court actions, it is not possible to predict the regulations that will be in place at the time of a particular jurisdictional determination by the Corps. Therefore, this jurisdictional delineation focuses on identifying the boundaries of potentially jurisdictional water bodies, utilizing methods for determining the locations of ordinary high water mark (OHWM) and wetland boundaries as described below. These methods for determining the boundaries of water bodies in general have not substantially changed over the years and are not likely to change with revised regulations. This delineation can then be used in combination with a companion jurisdictional analysis to determine which of the identified water bodies is actually jurisdictional, based on the definition that is in effect at the time of a jurisdictional determination by the Corps. In some cases it may be possible to identify water bodies that are likely or unlikely to be jurisdictional under any scenario, i.e., based on the 2015 WOTUS definition, previous regulations and Ropanos guidance, or proposed regulations. Any definition is likely to include the following categories of waters: (i) All watecs which ace rnrrently osed, wece used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; (ii) Alt interstate waters, including interstate wetlands; (iii) The territorial seas; (iv) All impoundments of waters otherwise identified as waters of the United States; (v) Tributaries of waters identified in paragraphs (i) through (iii) above; however the definition of tributary, based on the nature and amount of flow, is subject to change as regulations are revised; and P ,\HCR190S -ECR ot Cannon Rd lmprovement,\J0\)0 _Report_Final_rovMarch20lO.doc, •3/30/2020• 4 JURISDICTIONAL DWNEATIOM REPORT Re,ISEO MARCO 2020 El CAMLNO R,AL Al CANNON ROAD INHRSECTION IMPROVE..,ENT> PROJECT C .. LSSAD, CALlfO,NIA (vi) Wetlands adjacent to any of the above. I C: Similarly, certain water bodies are likely to be excluded, pursuant to one of the following: 1) specific rules; 2) the preamble to the 1986 regulations; 3) the SWANCC decision; or 4) Ropanos guidance; examples include: (i) Isolated waters; (ii) Artificial, ephemeral ditches, excavated on dry land and draining only uplands; (iii) Erosional features that do not meet the definition of tributary; (iv) Storm water control features created in dry land; (v) Artificial reflecting pools or swimming pools and ornamental waters; and (vi) Incidental depressions created in dry land. As applicable, waters in the above categories are noted in this delineation; the relationships of waters in other categories likely to be jurisdictional waters are also noted, but without speculation as to their future jurisdictional status. The Corps typically considers any body of water displaying an OHWM for designation as WOTUS. Subject to the applicable definition of WOTUS, Corps jurisdiction over nontidal WOTUS extends laterally to the OHWM or beyond the OHWM to the limit of any contiguous wetlands, if present. The OHWM is defined 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 litter and debris, or other appropriate means that consider the characteristics of the surrounding area" (33 CFR 328.3). Jurisdiction typically extends upstream to the point where the OHWM is no longer perceptible. Waters found to be isolated and not subject to CWA regulation may still be regulated by the RWQCB under the State Porter-Cologne Water Quality Control Act (Porter-Cologne Act). Wetlands Wetland delineations for Section 404 purposes must be conducted according to the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (Regional Supplement) (Corps 2008) and the Corps of Engineers 1987 Wetland Delineation Manual (1987 Manual) (Environmental Laboratory 1987). Where there are differences between the two documents, the Regional Supplement takes precedence over the 1987 Manual. The Corps and the United States Environmental Protection Agency (EPA) define wetlands as follows: Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support., a prevalence of vegetation typically adopted to life in saturated soil conditions.

Each characteristic has a specific set of mandatory wetland criteria that must be satisfied for that particular wetland characteristic to be met. Several indicators may be analyzed to determine whether the criteria are satisfied. Hydrophytic vegetation and hydric soils indicators provide evidence that episodes of inundation have lasted more than a few days or have occurred repeatedly over a period of years, but do not confirm that an episode has occurred recently. Conversely, wetland hydrology indicators provide evidence that an episode of inundation or soil saturation occurred recently, but do not provide evidence that episodes lasted more than a few days or occurred repeatedly over a period of years. Because of this, if an area lacks one of the three characteristics under normal circumstances, the area is considered nonwetland under most circumstances. Determination of wetland limits may be obfuscated by a variety of natural environmental factors or human activities, collectively called difficult wetland situations, including cyclic periods of drought and flooding or highly ephemeral stream systems. During periods of drought, for example, bank return flows are reduced and water tables are lowered. This results in a corresponding lowering of ordinary high water and invasion of upland plant species into wetland areas. Conversely, extreme flooding may create physical evidence of high water well above what might be considered ordinary and may allow the temporary invasion of hydrophytic species into nonwetland areas. In highly ephemeral systems typical of Southern California, these problems are encountered frequently. In these situations, professional judgment based on years of practical experience and extensive knowledge of local ecological conditions comes into play in delineating wetlands. The Regional Supplement provides additional guidance for difficult wetland situations. Hydrophytic Vegetation Hydrophytic vegetation is plant life that grows and is typically adapted for life in permanently or periodically saturated soils. The hydrophytic vegetation criterion is met if more than 50 percent of the dominant plant species from all strata (tree, shrub, herb, and woody vine layers) are considered hydrophytic. Hydrophytic species are those included on the 2016 National Wetland Plant list (lichvar et al. 2016) published by the Corps. Each species on the list is rated according to a wetland indicator category, as shown in Table A. Table A: Hydrophytic Vegetation Category Probability Obligate Wetland OBL Almost always occur in wetlands (estimated probability> 99%) Facultative Wetland FACW Usually occur in wetlands (estimated probability 67-99%) Facultative FAC Equally likely to occur in wetlands and nonwetlands (estimated probability 34-66%) Facultative Upland FACU Usually occur in nonwetlands (estimated probability 67-99%) Obligate Upland UPL Almost always occur in nonwetlands {estimated probability > 99%} To be considered hydrophytic, the species must have wetland indicator status (i.e., be rated Obligate Wetland [OBL], Facultative Wetland [FACW], or Facultative [FAC]).

CH 2020 El (AMINO ReAL AT CANNON ROAD IN'EAS,CTION IMPROVSMENTS PRDJSCl CA•,sa•o, c,,1,0••1• I C:: The delineation of hydrophytic vegetation is typically based on the most dominant species from each vegetative stratum (strata are considered separately); when more than SO percent of these dominant species are hydrophytic (i.e., FAC, FACW, or OBL), the vegetation is considered hydrophytic. In particular, the Corps recommends the use of the "50/20" rule (also known as the dominance test) from the Regional Supplement for determining dominant species. Under this method, dominant species are the most abundant species that immediately exceed 50 percent of the total dominance measure for the stratum, plus any additional species comprising 20 percent or more of the total dominance measure for the stratum. In cases where indicators of hydric soil and wetland hydrology are present but the vegetation initially fails the dominance test, the prevalence index must be used. The prevalence index is a weighted average of all plant species within a sampling point. The prevalence index is particularly useful when communities only have one or two dominants, where species are present at roughly equal coverage, or when strata differ greatly in total plant cover. In addition, Corps guidance provides that morphological adaptations may be considered when determining hydrophytic vegetation when indicators of hydric soil and wetland hydrology are present (Corps 2006). If the plant community passes either the dominance test or prevalence index after reconsidering the indicator status of any plant species that exhibit morphological adaptations for life in wetlands, then the vegetation is considered hydrophytic. Hydric Soils Hydric soils1 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.2 Soils are considered likely to meet the definition of a hydric soil when one or more of the following criteria are met: 1. All Histels except Folistels and Histosols except Folists; 2. Soils that are frequently ponded for a long duration or very long duration3 during the growing season; or 3. Soils that are frequently flooded for a long duration or very long duration during the growing season. Hydric soils develop under conditions of saturation and inundation combined with microbial activity in the soil that causes a depletion of oxygen. While saturation may occur at any time of year, microbial activity is limited to the growing season, when soil temperature is above biologic zero (the soil temperature at a depth of 50 centimeters, below which the growth and function of locally adapted plants are negligible). Biogeochemical processes that occur under anaerobic conditions during the growing season result in the distinctive morphologic characteristics of hydric soils. Based on these criteria and on information gathered from the National Soil Information System (NASIS) The hydric soils definition and criteria included in the 1987 Manual are obsolete. Users of the 1987 Manual are directed to the United States Department of Agriculture (USDA) NRCS website for the most current information on hydric soils. Current definition as of 1994 (Federal Register, July 13, 1994). "Long duration" is defined as a single event lasting from 7 to 30 days; qvery long duration" is defined as a single event that lasts longer than 30 days.

The Regional Supplement has a number of field indicators that may be used to identify hydric soils. The NRCS (2017) has also developed a number of field indicators that may demonstrate the presence of hydric soils. These indicators include hydrogen sulfide generation, accumulation of organic matter, and the reduction, translocation and/or accumulation of iron and other reducible elements. These processes result in soil characteristics that persist during both wet and dry periods. Separate indicators have been developed for sandy soils and for loamy and clayey soils. Wetland Hydrology Under natural conditions, development of hydrophytic vegetation and hydric soils is dependent on a third characteristic: wetland hydrology. Areas with wetland hydrology are those where the presence of water has an overriding influence on vegetation and soil characteristics due to anaerobic and reducing conditions, respectively (Environmental Laboratory 1987). The wetland hydrology criterion is satisfied if the area is seasonally inundated or saturated to the surface for a minimum of 14 consecutive days during the growing season in most years (Corps 2008). Hydrology is often the most difficult criterion to measure in the field due to seasonal and annual variations in water availability. Some of the indicators that are commonly used to identify wetland hydrology include visual observation of inundation or saturation, watermarks, recent sediment deposits, surface scour, and oxidized root channels (rhizospheres) resulting from prolonged anaerobic conditions. California Department of Fish and Wildlife The CDFW, through provisions of the California Fish and Game Code (Sec. 1600 et seq.), is empowered to issue agreements for any alteration of a river, stream, or lake where fish or wildlife resources may be adversely affected. Streams {and rivers) are defined by the presence of a channel bed and banks and at least an intermittent flow of water. The CDFW regulates wetland areas only to the extent that those wetlands are part of a river, stream, or lake as defined by the CDFW. Also, the CDFW typically does not regulate estuaries below the mouth of a tributary river or stream. In obtaining CDFW agreements, the limits of wetlands are not typically determined. The reason for this is that the CDFW generally includes, within the jurisdictional limits of streams and lakes, any riparian habitat present. Riparian habitat includes willows, mule fat, and other vegetation typically associated with the banks of a stream or lake shorelines and may not be consistent with Corps definitions. In most situations, wetlands associated with a stream or lake would fall within the limits of riparian habitat. Thus, defining the limits of CDFW jurisdiction based on riparian habitat will automatically include any wetland areas and may include additional areas that do not meet Corps criteria for soils and/or hydrology (e.g., where riparian woodland canopy extends beyond the banks of a stream away from frequently saturated soils).

Section 401 of the CWA specifies that certification from the State is required for any applicant requesting a Federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities that may result in any discharge into navigable waters. The Porter-Cologne Act requires "any person discharging waste, or proposing to discharge waste, within any region that could affect the waters of the State" to file a report of discharge. Typically, the areas subject to RWQCB jurisdiction coincide with those of the Corps (i.e., waters of the U.S., including any wetlands). California Coastal Commission The CCC, through provisions of the California Coastal Act, is empowered to issue a Coastal Development Permit (CDP) for many projects located within the Coastal Zone. In areas where a local entity has a certified Local Coastal Program {LCP), the local entity {e.g., City of Carlsbad) can issue a CDP only if it is consistent with the LCP. The CCC, however, has appeal authority for portions of the LCPs and retains jurisdiction over certain public trust lands and in areas without an LCP. The CCC's definition of wetlands, as defined in Section 30121 of the Coastal Act and Title 14, Section 13577 of the CCC's regulations, is distinctly different from the Corps definition of wetlands. According to the CCC's regulations, wetlands are defined as "land where the water table is at, near, or above the land surface long enough to promote the formation of hydric soils orto support the growth of hydrophytes." Both definitions focus on three fundamental wetland characteristics: hydrology, soils, and vegetation. However, while the Corps definition requires the existence of all three wetland characteristics for an area to be considered a wetland, the CCC's definition of wetlands is based on the existence of only one characteristic: wetland hydrology sufficient to either support a prevalence of hydrophytic vegetation or promote the formation of hydric soils (exceptions include certain areas that lack wetland soils and vegetation). Under certain circumstances, reliable indicators of all required characteristics are not necessarily apparent, and areas may be delineated as wetlands by the Corps on the basis of indicators of only two of the three characteristics. The CCC routinely makes jurisdictional wetlands determinations based on the presence of one characteristic indicator (i.e., wetland soils or vegetation) under the assumption that wetland hydrology must be present in order for the indicator to be present. Nevertheless, the presence of wetland hydrology during some portion of most years is fundamental to the existence of any wetland, and the CCC will sometimes disregard vegetation or soil indicators when sufficient evidence exists to conclusively refute the presence of wetland hydrology. METHODOLOGY LSA Biologists Jaime Morales and Scott Batchelder performed the jurisdictional delineation fieldwork on December 10, 2014. LSA prepared a field map of the area to be surveyed using a 2014 aerial photograph base at a scale of 1 inch= 56.25 feet. The study area was surveyed on foot, and all areas of potential jurisdiction were evaluated according to Corps and CDFW criteria.

LSA evaluated areas supporting hydrology or species of plant life potentially indicative of wetlands according to routine wetland delineation procedures described in the Regional Supplement. Representative sample points were selected and examined in the field in those areas where wetland jurisdiction was in question or needed to be confirmed. At each sample point, the dominant and subdominant plant species were identified and their wetland indicator status (Uchvar et al. 2014) noted. A small sample pit (approximately 15-20 inches deep) was dug at each point in order to examine soil characteristics and composition. Soil matrix colors were classified according to the Munsell Soil Color Charts (Munsell Color 2000). Hydrological conditions, including any surface inundation, saturated soils, groundwater levels, and/or other wetland hydrology indicators, were recorded. General site characteristics were also noted. Standard data forms were completed for each sample point; copies of these data forms are included in Appendix A of this report. LSA performed a follow-up site visit on April 30, 2018, to assess the study area for any changes to aquatic resources. No significant changes to the limits or classifications of aquatic resources were observed. LSA visited the site on April 22, 2019, to again assess the study area for any changes to aquatic resources and to prepare an Arid West Ephemeral and Intermittent Streams OHWM datasheet to determine the limits of the OHWM of the creek. No significant changes to the limits or classifications of aquatic resources were observed during this visit. RESULTS Within the study area, a segment of Agua Hedionda Creek flows from northeast to southwest in a developed area. The creek flows unobstructed beneath the Agua Hedionda Creek Bridge. Additionally, hydrophytic vegetation and hydric soils occur at the southeastern corner of the study area. This area does not receive flows from Agua Hedionda Creek; rather, it is at a similar elevation to the creek and the hydrophytic vegetation is likely supported by a high water table. A vegetated berm and unpaved access road separate this area from Agua Hedionda Creek. LSA presumes that a hydraulic connection exists between Agua Hedionda Creek and the area dominated by hydrophytic vegetation that is outside of the OHWM. Based on the hydraulic connection (i.e., hydrology), prevalence of hydrophytic vegetation, and presence of hydric soils, LSA considers this area to be wetland waters of the United States that are adjacent to Agua Hedionda Creek. Agua Hedionda Creek ultimately flows to the Pacific Ocean (a Traditional Navigable Water of the U.S.). Because of the direct connection with the Pacific Ocean, this feature is subject to Corps jurisdiction to the OHWM and adjacent wetlands. The areas mapped as wetlands meet all three criteria for wetland waters of the U.S.: wetland hydrology, hydric soils, and dominance of hydrophytic plant species. However, based on recent guidance from Corps staff, areas within the OHWM that meet all three criteria for wetland waters of the U.S. are mapped as nonwetland waters of the U.S. Streambed and banks, including riparian scrub vegetation associated with this drainage feature, are subject to CDFW jurisdiction.

Functions and values for this feature were determined to have a moderate to high significance in terms of resources. Figure 2 depicts the location of this feature and Figure 3 shows site conditions. The wetland determination data forms {Appendix A) contain full descriptions of the results of each sample point, while the Arid West Ephemeral and Intermittent Streams OHWM datasheet (Appendix B) describes the OHWM of the feature. Appendix C describes and evaluates the functions and values of the feature within the study area. Vegetation The study area contains the following vegetation communities and land uses: riparian scrub, freshwater marsh, coastal sage scrub, ornamental vegetation, unvegetated stream channel, open water, disturbed land, developed areas, and bare ground. The hydrophytic vegetation criterion for Corps jurisdictional wetlands is satisfied when there is a prevalence of wetland vegetation. Areas identified in this report as wetlands are dominated by wetland vegetation and are subject to Corps (outside of the OHWM), CDFW, and CCC jurisdiction. Drainage-associated riparian scrub vegetation occurring beyond the stream bank is also subject to CDFW and CCC jurisdiction. Within the study area, wetland vegetation was only present south of the Agua Hedionda Creek Bridge. Freshwater marsh, dominated by broadleaf cattail (Typha /atifo/ia OBL), and to a lesser extent by salt grass (Distich/is spicata FAC), pickleweed (Sa/icornia virginica OBL), salty Susan (Jaumea camosa OBL), and Mexican rush (Juncus mexicanus FACW), was observed within the drainage, while riparian scrub, dominated by arroyo willow (Salix /asio/epis FACW), Goodding's black willow (Salix gooddingii FACW), red willow (Salix /aevigata FACW), mule fat (Baccharis saficifolia FACW), and Brazilian pepper tree (Schinus terebinthifo/ius FAC), was observed on the banks. Wetland vegetation was also present at the southeastern corner of the study area. Although this area does not receive flows from Agua Hedionda Creek, it is at a similar elevation to the creek and a high water table likely supports the broadleaf cattail-dominated freshwater marsh and riparian scrub habitats. North of the Agua Hedionda Creek Bridge, the terraces on either ~ide of the open water are unvegetated due to frequent inundation; therefore, these areas were classified as unvegetated stream channel because they were still within the bounds of the stream banks and OHWM. Beyond the areas designated as unvegetated stream channel (upslope), upland vegetation (nonnative grassland), dominated by Bermuda grass (Cynodon dacty/on FACU), burclover (Medicago polymorpha FACU), and cheeseweed (Malva parviflora FACU) was present. Additionally, Mexican fan palm (Washingtonia robusta FACW) sprouts were abundant in this area. Some of the areas vegetated by nonnative grassland showed evidence of flooding, such as drift deposits and matted vegetation. The OHWM was extended to include these areas within the active floodplain that inundate during high discharge events.

Sample plots were taken within the study area above and below the observed OHWM where wetland vegetation was present in order to identify the limits of potential jurisdictional areas. Previously referenced Figure 2 depicts the locations of the sample plots. Soil Pit (SP) 1 was dug in an eastern terrace of Agua Hedionda Creek, within unvegetated stream channel and the creek's active floodplain. This sample plot was chosen because it had the potential to meet the Corps' three criteria based on visual inspection. Soils within the pit consisted of sandy loam and sand. The profile at this location included a layer that was approximately 3 inches thick, with 100 percent of the matrix composed of the correct combination of hue, value, and chroma (Munsell moist lDYR 3/2) to meet the hydric soils indicator Sandy Mucky Mineral (51), as outlined in the Regional Supplement. Between 3 and 16 inches, 100 percent of the matrix was classified as 7.5YR 3/2. Although wetland hydrology was evident and hydric soils were present, the hydrophytic vegetation criterion was not met due to the dominance of Bermuda grass (FACU), despite the presence of Mexican fan palm sprouts (FACW). SP 2 was also dug in the eastern terrace of Agua Hedionda Creek, south of SP 1 and slightly higher in elevation than SPl, although still within the creek's active floodplain. This sample plot was also chosen because it had the potential to meet the Corps' three criteria based on visual inspection. Soils within the pit consisted of silty clay. The profile at this location included a layer that was approximately 10 inches thick consisting of a uniform matrix (100 percent) classified as lOYR 3/2. Soils within the pit did not display any hydric soils indictors. Although wetland hydrology was evident, hydrophytic vegetation criterion was not met due to the dominance of Bermuda grass (FACU), despite the presence of Mexican fan palm sprouts (FACW) and annual beard grass (Pofypogon monspeliensis FACW). SP 3 was also dug on the north side of the Agua Hedionda Creek Bridge, on the eastern bank of Agua Hedionda Creek, slightly higher up the bank (outside of the active floodplain) in order to identify the point at which hydric indicators were absent. Soils within the pit consisted of silty clay. The profile at this location included a layer that was approximately 10 inches thick consisting of a uniform matrix (100 percent) classified as lOYR 3/2. Between 10 and 16 inches, 95 percent of the matrix was classified as lOYR 4/2 and the remaining S percent of the matrix was classified as 2.SYR 5/8. These findings meet the Depleted Matrix (F3) hydric soils indicator, as outlined in the Regional Supplement. Although analysis of this sample plot was not necessary because Sample Plots 1 and 2 were not within wetlands, it was chosen because it was clearly dominated by an upland ornamental species, sea fig (Corpobrotus chifensis FACU). The point of this plot was to test for hydric soils and wetland hydrology. Only hydric soils were present at this sample plot.

These findings meet the Depleted Matrix (F3) hydric soils indicator, as outlined in the Regional Supplement. Vegetation in the area was dominated by willow (Salix sp.) trees, and wetland hydrology was evident. Although this sample plot meets the Corps' three wetland criteria, it is considered nonwetland waters of the U.S. because it is within the OHWM. Although areas upslope and outside of the OHWM did contain hydrophytic vegetation and hydric soils, wetland hydrology was no longer identified. SP 5 was also dug on the eastern bank of Agua Hedionda Creek (south of the Agua Hedionda Creek Bridge), slightly upslope from SP 4, outside of the OHWM. Soils within the pit consisted of sandy texture. The profile at this location included a layer that was approximately 16 inches thick consisting of a uniform matrix (100 percent) classified as lOYR 4/2. Soils within the pit did not display any hydric soils indictors. This sample plot was chosen to demarcate the limit of wetland hydrology beyond the OHWM. As it was slightly upslope from SP 4, wetland hydrology and hydric soils were no longer present at this elevation, although a predominance of hydrophytic vegetation was present. SP 6 was dug south of El Camino Real; however, not within Agua Hedionda Creek. This pit was dug to the east, beyond an unpaved access road and a patch of coastal sage scrub, on the border of the coastal sage scrub and freshwater marsh habitats. Soils within the pit consisted of silty clay. The profile at this location included a layer that was approximately 3 inches thick, with 100 percent of the matrix identified as lOYR 3/2. Between 3 and 16 inches, 95 percent of the matrix was identified as lOYR 4/2 and contained redox features that were identified as 2.SYR 4/8. These findings meet the Depleted Matrix (F3) hydric soils indicator, as outlined in the Regional Supplement. This sample plot was chosen because it appeared to be the boundary of areas that would meet the Corps' three wetland criteria. Upon further analysis, this sample plot did mark the boundary of what the Corps considers adjacent wetlands, as the wetlands occurred adjacent to the OHWM of Agua Hedionda Creek. Another sample plot in this area was not necessary because upland vegetation (coastal sage scrub) was present immediately upslope from SP 6. Hydrology Wetland hydrology was evident within Agua Hedionda Creek and to the east in the freshwater marsh/riparian scrub habitat (surrounding SP 6). The following wetland hydrology indicators were observed: water stained leaves (B9; a primary wetland hydrology indicator described in the Regional Supplement), aquatic invertebrates (B13; a primary indicator), oxidized rhizospheres along living roots (C3; a primary indicator), the presence of reduced iron (C4; a primary indicator), drainage patterns (B10; a secondary indicator), thin muck surlace (C7; a secondary indicator), and drift deposits (B3; a secondary indicator).

Therefore, areas within the coastal zone (west of the eastern edge of the El Camino Real right~of- way) that are subject to CDFW jurisdiction are considered CCC Wetlands. Table D displays the acreages of potential CCC jurisdictional wetlands present within the study area. Table D· Potential CCC Wetlands within the Study Area .

ABSTRACT The Ordinary High Water Marl< (OHWM) is a method used to identify the lateral limits of non-wetland waters. Lichvar and McColley (2008) developed an OHWM delineation manual for ephemeral and intermittent streams in the Arid West. Their approach identified key hydrologic, geomorphic, and vegetation indicators useful in OHWM delineation. This technical note provides an updated datasheet to the manual. The datasheet has been sin-.,lified but still includes the overall field signatures and preliminary methods used to determine the OHWM. The datasheet now focuses on identifying the characteristics of each individual hydrogeomorphic tloodplain unit and uses the differences between the floodplain units to identify the OHWM. 15.

All waters have some degree of functionality, and no single drainage can perform all of the functions considered below. The following functions are analyzed at low, moderate, or high value levels. The individual drainages are analyzed in Table C-1 (following) based on the criteria outlined below. HYDROLOGIC REGIME This function is the ability of a wetland or stream to absorb and store water belowground. The degree of this saturation is dependent on the soil composition and is affected by prior flooding events. For example, clay soils possess more pore space than sandy soils. However, the smaller pore size slows the rate at which water is absorbed and released and, therefore, clay soil has a lower capacity to store water than sandy soils. The storage of water belowground allows for the fluctuation between anaerobic and aerobic conditions that benefit environmental conditions necessary for microbial cycling. FLOOD STORAGE AND FLOOD FLOW MODIFICATION This function is determined based on the ability of a wetland or stream at which the peak flow in a watershed can be attenuated during major storm events and during peak domestic flows to take in surface water that may otherwise cause flooding. This is dependent on the size of the wetland or stream, the amount of water it can hold, and the location in the watershed. For instance, larger wetlands or streams that have a greater capacity to receive waters have a greater ability to reduce flooding. In addition, areas high in the watershed may have more ability to reduce flooding in downstream areas, but areas lower in the watershed may have greater benefits to a specific area. Vegetation, shape, and the configuration of the wetland or stream may also affect flood storage by dissipating the energy offlows during flood events. SEDIMENT RETENTION Removal of sediment is the process that keeps sediments from migrating downstream. This is accomplished through the natural process of sediment retention and entrapment. This function is dependent on the sediment load being delivered by runoff into the watershed. Similar to above, the vegetation, shape, and configuration of a wetland will also affect sediment retention if water is detained for long durations, as would be the case with dense vegetation, a bowl-shaped watershed, or slow-moving water. This function would be demonstrated (i.e., high) if the turbidity of the incoming water is greater than that of the outgoing water. NUTRIENT RETENTION AND TRANSFORMATION Nutrient cycling consists of two variables: uptake of nutrients by plants and detritus turnover, in which nutrients are released for uptake by plants downstream. Wetland systems in general are P:\HCR1905 • ECR ot C.n""n Rd lmpro'"'monts\JD\JD _ Report_F1r,al_revMacch2020.doc, •3/30/2020• C-1 JURISDICTIO"Al DHINEATION Reeo•r Re,,srn MARCH 2020 EL CAMl•o REAL AT CANNO" ROAD INTERSECTION IMe,OV,M,STS P,oJeCT (ARlSOAD, CALIFORNtA I C: much more productive with regard to nutrients than upland habitats. The regular availability of water associated with the wetland or stream may cause the growth of plants (nutrient uptake) and associated detritivores and generate nutrients that may be utilized by a variety of aquatic and terrestrial wildlife downstream. TOXICANT TRAPPING The major processes by which wetlands remove nutrients and toxicants are as follows: (1) by trapping sediments rich in nutrients and toxicants, (2) by absorption into soils high in clay content or organic matter, and {3) through nitrification and denitrification in alternating oxic and anoxic conditions. Removal of nutrients and toxicants is closely tied to the processes that provide for sediment removal. SOCIAL SIGNIFICANCE This is a measure of the probability that a wetland or stream will be utilized by the public for its natural features, economic value, official status, and/or location. This includes public use for recreational uses, such as boating, fishing, birding, walking, and other passive recreational activities. In addition, a wetland or stream that is utilized as an outdoor classroom, is a location for scientific study, or is near a nature center would have a higher social significance standing. WILDLIFE HABITAT General habitat suitability is the ability of a wetland to provide habitat for a wide range of wildlife. Vegetation is a large component of wildlife habitat. As plant community diversity increases along with connectivity with other habitats, so does potential wildlife diversity. In addition, a variety of open water, intermittent ponding, and perennial ponding is also an important habitat element for wildlife. AQUATIC HABITAT The ability of a wetland or stream to support aquatic species requires that there be ample food supply, pool and riffle complexes, and sufficient soil substrate. Food supply is typically in the form of aquatic invertebrates and detrital matter from nearby vegetation. Poot and riffle complexes provide a variety of habitats for species diversity as well as habitat for breeding and rearing activities. Species diversity is directly related to the complexity of the habitat structure.

Jill Carpenter, LSA Senior Biologist/Bat Specialist Fall/Winter Season Nighttime Bat Survey at the El Camino Real Bridge over Agua Hedionda Creek (LSA Project No. HCR1402), City of Carlsbad, San Diego County, California This memorandum documents the results of a nighttime bat survey conducted on November 11, 2015, at the El Camino Real bridge crossing of Agua Hedionda Creek in San Diego County (Figure l; all figures attached) for the El Camino Real at Cannon Road Intersection Improvements project (project). Specifically, the study area for the project is located within the City of Carlsbad, and encompasses the northeastern and southeastern comers of the intersection of El Camino Real and Cannon Road. Due to the reported historic observations of large numbers of bats roosting within the El Camino Real Bridge over Agua Hedionda Creek, a preliminary daytime bat habitat suitability assessment for the El Camino Real at Cannon Road Intersection project was deemed unnecessary. Instead, two nighttime bat surveys were recommended during two separate seasons, with those surveys to be perfonned as soon as possible in advance of project construction. Separate seasonal surveys are needed because species composition and the numbers of bats often change seasonally at a given roost site, and because potential impacts to bats from construction activities associated with the El Camino Real at Cannon Road Intersection Project cannot be adequately assessed, nor can appropriate species-specific minimization measures be detennined, without adequate knowledge of the size(s) and species composition, including any seasonal variation if present, of any bat colonies roosting within the bridge. These seasonal surveys will also serve as preconstruction surveys for the project. This nighttime survey comprises the first of the two recommended seasonal surveys, and was perfonned during the fall/winter season to ascertain the size and species composition of any bats potentially utilizing the bridge as an overwintering roost site, as well as how the bats are distributed throughout the bridge during the fall/winter. This infonnation is useful in determining how many bats will be displaced and, therefore, subject to temporary impacts from humane evictions or exclusions, which are typically perfonned during the fall season, should those actions be warranted to prevent direct mortality. An additional survey will be perfonned at the El Camino Real bridge between June 1 and August 15, which coincides with the peak period of the bat maternity season (April ]-August 31 ), in order to adequately assess the potential for project-related impacts to nursery colonies of bats, including flightless young. In addition to discussing the results of the fall/winter season nighttime bat survey, this memorandum includes preliminary recommendations to minimize potential impacts to bats from activities associated with the proposed widening of the El Camino Real Bridge as part of the El Camino Real at Cannon Road Intersection Improvements project. More precise recommendations will be prepared following the completion of the summer maternity season survey. l /29/16 "P:\HCR 1402\Biology\Bat Surve} \BatNightSurve} _ ElCammoReal docx» !SA ,\SSOCl,\l"IS 1,-,,; BACKGROUND Bat populations are generally declining throughout Southern California and globally due to various factors including loss of roosting and foraging habitats, exposure to pesticides and pathogens, and direct extermination (Johnston et al. 2004; Miner and Stokes 2005). Because bats have low reproductive turnover (most species have only one young per year, and only a few species have twins or multiple births) and high juvenile mortality, it can take many years for a colony or population of bats to recover from any impacts that result in morta1ity or even in a decrease in reproductive ability. As natural roost sites become scarcer due to urban development and changes in land use, the use of humanmade structures such as bridges and buildings as roost sites by some bat species has increased as bats seek alternative roosting options (Erickson et al. 2003). The importance and ecological value of anthropogenic structures as roosts has consequently increased to the point that many of these '·artificial" roost sites are becoming essential to the survival of local bat populations (Johnston et al. 2004; Smith and Stevenson 2013). However, these anthropogenic roosting sites are also highly vulnerable because bats are often driven out or killed once they are discovered occupying humanmade structures. Even bats attempting to roost in landscape plantings can be subject to impacts from tree removal or trimming activities such as the trimming of palm fronds. Therefore, as urban and suburban development occurs across the landscape, many of these areas may act as habitat "sinks"1 where bats may at first appear to be relatively common and may even be attracted to humanmade structures, but then decrease in abundance over time as development of that area continues (Miner and Stokes 2005; Remington 2000). The protection of bat roosting and foraging habitat, particularly those identified as being maternity or nursery sites, is, therefore, considered during the environmental review process to prevent potentially significant negative effects to or further loss ofremaining populations. Day roosts protect bats from predators and the elements during the day while resting and/or rearing their young. Examples of day-roosting sites include, but are not limited to, anthropogenic structures, trees, cliff or rock crevices, caves, and mines. In humanmade structures such as bridges and culverts. day roosts are typically in expansion joints, hinges, or other crevices. Some types of day roosts where bats are particularly vulnerable to disturbance include maternity colonies, where female bats congregate in the spring and summer months to give birth and raise young, and hibemacu\a, where bats enter a period of hibernation during the winter months. A night roost, on the other hand, refers to a structure or structural feature (natural or humanmade) in which bats roost during the evening between foraging bouts; in addition to crevices, examples of night-roosting habitat include cavities, comers, culvert walls, and recessed open spaces that are sheltered from the wind. Night roosts are typically situated in or near a foraging area and play an important role in the energetics and social interaction of bats. When a night roost is eliminated, the energetics for bats to successfully utilize the surrounding foraging area may be negatively affected. Day roosts may also double as night roosts, particularly if they are situated in or near a foraging area Since bats have separate roosting and foraging habitat requirements, it is expected that some bats may utilize one area for foraging and another for roosting. While more extensive and direct impacts to bats occur through roost removal, destruction, or disturbance, indirect impacts such as decline of prey base due to loss or modification of foraging habitat can also be substantial. Therefore, when assessing an area with regard to proposed alterations to habitat, a landscape-level approach is required to adequately determine potential impacts to bats. A habitat sink refers to an area where the productivity of a given species is insufficient to offset mortality. 1/291 16 «P·"JiCR ! 402\Biology\.Elac Survey'illatNightSurvey _ EICaminoReal docx» 2 L>A ASSO<;]Al U. IN<: METHODS On the evening of November 11, 2015, LSA Associates, Inc. (LSA) Senior Biologist and bat specialist Jill Carpenter performed a nighttime bat survey at the El Camino Real Bridge over Agua Hedionda Creek in order to evaluate use of the structure by bats as a day and/or night roost during the fall/winter season. Ms. Carpenter was assisted by LSA biologist Lonnie Rodriguez, who has past experience assisting with nighttime emergence and acoustic bat surveys. Prior to the emergence period and exit count portion of the survey, the crevices between the concrete box beams were examined for the presence of day-roosting bats with a high-intensity spotlight, and the approximate numbers, distribution, and species of bats observed were marked on a hand-drawn map. The exit count portion of the survey was subsequently initiated one-half hour before sunset and continued until one hour after sunset. An observer was positioned on each side of the bridge at a vantage point that would optimize visibility of any bats that may exit or enter the bridge in order to obtain an estimate of the number of day-roosting bats present, and to correlate the acoustic data recorded with visual observations. Numbers ofbats exiting or entering the bridge were recorded using tally counters. Observers remained in position counting bats until one hour after sW1set. Following completion of the emergence period, the biologists performed a second spotlight examination of the crevices between the concrete box beams to detennine how many, if any, bats remained in the roost crevices. for the remaining hour of the survey period, the biologists assessed the level ofnight- roosting activity beneath the bridge by observing and documenting any bat activity in the vicinity of the structure using night vision equipment. Three Pettersson D240X and one Wildlife Acoustics EchoMeter 3+ ultrasound detectors were used in time expansion mode to collect acoustic data during the entirety of each nighttime survey, and digital media players or secure digital (SD) memory cards were used to record the call files. These data, consisting of full-spectrum sonograms of echolocation calls, were subsequently analyzed using SonoBat 2.9 acoustic analysis software. Species identifications were made by comparing call recordings with a library of"voucher" calls from known hand-released bats. Some limitations are inherent in acoustic monitoring and in the analysis of acoustic data and include (but are not limited to) human bias and past experience in data interpretation, as well as the fact that some species are not equally detectable or may not be recorded at all. For example, some bats (e.g., Mexican free-tailed bats [Tadarida brasiliensis]) emit loud low-frequency echolocation calls that can be recorded from great distances and will be overrepresented in the data, while "whispering" bats (e.g., Townsend's big-eared bats [Cmynorhinus townsendii]) emit faint calls that may not be recorded at all. In addition, not all call sequences are identifiable. Different bat species may use similar types of echolocation calls, or the same species may use different types of echolocation calls based on the perceptual task and the immediate environment or habitat. In addition, not all bats recorded will be those exiting or entering the bridge in question. Some are foraging bats en route to or from other structures. It is important, therefore, to have observers on site in order to correlate calls with visual observations. RESULTS AND DISCUSSION The study area comprises a section of Agua Hedionda Creek, which contained flowing as well as ponded water at the time of this survey. The area surrounding the El Camino Real bridge over Agua Hedionda Creek is characterized by open water as well as ornamental vegetation associated with adjacent urban development on the northern side of the bridge, and native habitats such as riparian scrub, freshwater marsh, open freshwater, and coastal sage scrub on the southern side of the bridge 1129/16 «P. \JfCR 1402\.Biology\Bat Survey1Ba1NightSurvey _ EICanunoReal.docx» 3 I SA ASSO<,IATfS 1,;r; (Figure 2). All of these areas likely provide a variety of insect fauna for foraging, increasing the desirability of the bridge structure for use as a day and night roost. The El Camino Real Bridge is a concrete box beam bridge. In this type ofbridge design, the spaces between the concrete beams fonn crevices in the underside of the bridge deck and offer shelter from inclement weather and potential predators; as a result, the entire length of the El Camino Real bridge over Agua Hedionda Creek contains structural elements that are suitable for and commonly used by day-and night-roosting bats (Figures 2 and 3). Bats and bat sign (e.g., guano or urine staining) confinning use of the bridge by roosting bats were observed throughout the bridge (Figure 3). At least 440 day-roosting bats were counted during the pre-emergence spotlight inspection of the roost crevices at the El Camino Real bridge. These bats were primarily observed roosting in the crevices along the northern side of the bridge, with the largest numbers of bats roosting in the northern crevices of the middle section of the bridge. The majority of the bats day roosting in the bridge were visually identified as Mexican free-tailed bats. The remaining individuals, comprising less than a dozen of the bats roosting throughout the bridge, were identified visually and acoustically as Yuma myotis bats (Myotis yumanensis).1 A graphic rendering of the bridge layout showing the approximate numbers, distribution, and species of bats observed during the pre-emergence spotlight inspection is provided on Figure 4. It should be noted that accurate spotlight counts of roosting bats are often difficult to obtain when large numbers of bats are roosting in a given crevice because crevice-roosting bats tend to cluster or "stack" on top of each other; therefore, in some cases, a number is included on the graphic with a"+" sign indicating that this is a minimum number of bats present at that location, and that the presence of additional bats above those directly observed cannot be ruled out. During the emergence period, approximately 140 bats were observed exiting from the bridge, with the majority of the bats exiting the bridge on the north side. Many of the bats foraged beneath the bridge for several minutes before exiting the bridge area. At the conclusion of the emergence period, approximately 357 bats were counted as remaining in the roost crevices. Based upon the exit count numbers and the results of this post-emergence crevice inspection, the El Camino Real bridge supports an overwintering population of approximately 450-500 day-roosting bats2. While some populations of Mexican free-tailed bats in Southern California have been observed using bridges as roost sites year-round (person observation), fall and winter roost sites can also be important stopping points for species engaging in localized seasonal movements or migrating longer distances toward hibernation and/or wintering sites (Erickson et al. 2003; personal observation). Mexican free- tailed bats in particular are known to migrate away from colder areas of California and over-winter in areas with nonfreezing temperatures such as coastal areas, and although the details of these movements are not well understood, these migratory individuals (along with local resident populations of this species) appear to be active within their winter range. Although it is not known Some of the Myotis species can be difficult to identify to the species level without close examination in the hand; however, based on diagnostic observations of foraging behavior and diagnostic characteristics present in the acoustic data, this species was conclusively identified. Although approximately 440 bats were counted during the pre-emergence spotlight inspection, this is considered a "minimum" number based upon the aforementioned "stacking" behavior; therefore, this estimate is obtained from adding the numbers of bats counted exiting the bridge to the numbers of bats counted remaining within the bridge at the conclusion of the emergence period. 1 -'29i 16 «P·\HCR l 402\B,ology1Bat S...-vey\BatN ightSurvey _ EIC'aminoReal docx» 4 whether the individuals present in the El Camino Real bridge during this survey are present year- round, the El Camino Real bridge is likely an important overwintering site for the observed population of Mexican free-tailed bats and Yuma myotis. However, the bats are dispersed in relatively low concentrations throughout the El Camino Real bridge, and it appears that a sufficient amount of suitable habitat is present throughout the structure to house the overwintering population if bats are temporarily excluded from some of the roost crevices to prevent direct impacts from project construction. CONCLUSIONS AND RECOMMENDATIONS Bats and other nongame mammals are protected by California Fish and Game Code§ 4150, which states that all nongame mammals or parts thereof may not be taken or possessed except as provided otherwise in the code or in accordance with regulations adopted by the commission. Activities resulting in mortality of non game mammals ( e.g., destruction of an occupied non-breeding bat roost, resulting in the death of bats) or disturbance that results in the loss of a maternity colony of bats (including the death of young) may be considered "take" by the California Department of Fish and Wildlife (CDFW). ln addition, reported anecdotal observations of bats roosting at the El Camino Real bridge over Agua Hedionda Creek indicate that this bridge is used as a maternity roost by a large number of bats; as such, it is considered a native wildlife nursery site, and potential impacts should be minimized to the greatest extent practicable to avoid significant impacts to the viability of the local population. The species composition and numbers of bats utilizing the El Camino Real bridge as a maternity roost will be determined during the maternity season bat survey, which will be performed between June 1 and August 15. Two bat species, Mexican free-tailed bat and Yuma myotis, were observed and/or acoustically detected within the study area during the fall/winter season nighttime survey at El Camino Real bridge over Agua Hedionda Creek. An estimated 450---500 bats, predominantly Mexican free-tailed bats with approximately a dozen Yuma myotis, use the El Camino Real bridge as an overwintering roost site. These bats were primarily observed day roosting in the crevices along the northern side of the bridge, with the largest numbers of bats roosting in the northern crevices of the middle section of the structure. The overwintering bat population is dispersed in relatively low concentrations throughout the El Camino Real bridge, and it appears that a sufficient amount of suitable habitat is present throughout the structure to house the overwintering population if bats are temporarily excluded from some of those areas. Therefore, if a humane eviction/exclusion at a portion or portions of the bridge is determined to be necessary to prevent direct impacts, provision of alternate roosting habitat will not be needed if this exclusion is limited to September I-March 31, which is outside of the bat maternity season. However, since the numbers and distributions of bats present within the bridge during the maternity season are not known at this time, if bats will be prevented from roosting in portions of the bridge between April I and August 31, alternate roosting habitat may need to be installed to prevent potential impacts from this loss of roosting habitat during the maternity season. The determination with regard to whether or not alternate bat-roosting habitat will be needed to offset temporary impacts during the maternity season will be made once information on the size, species composition, and distribution of bat colonies using the El Camino Real bridge as a maternity.roost are obtained from the summer maternity season survey. I i29/16 «P IHCR 14021Biology1Bat SurveylBatN ightSurvey _ElCammoRealdoc,rn 5 To minimize potential impacts to roosting bats from project-related construction activities, LSA recommends the following preliminary measures, which may be revised following the completion of the maternity season survey: • Depending on the type(s) and location(s) of potential impacts during project-related construction activities, a humane eviction/exclusion may be warranted to prevent mortality of bats. If needed, humane evictions/exclusions should be performed by a qualified bat biologist in the fall (September or October) preceding construction to exclude bats from directly affected work areas and avoid potential direct impacts. However, exclusions are not always appropriate, and the decision of whether or not to implement a humane eviction/exclusion of bats should be made in consultation with a qualified bat biologist. It is particularly important to avoid direct impacts to bats during the maternity season (April I-August 31), when nonvolant (flightless) young are present. • Contingent upon the results of the maternity season survey, installation of alternate roosting habitat may be required by CDFW in conjunction with the humane eviction/exclusion to prevent impacts to maternity-roosting bats; however, alternate roosting habitat is not necessary for exclusion periods limited to September ]-March 31. • If permanent impacts such as removal or obstruction of bat-roosting habitat will occur from project construction, installation ofalternate roosting habitat may be required by CDFW to avoid permanent impacts to the maternity colony. • To minimize potential impacts to maternity-roosting bats, including nonvolant (flightless) young, activities that generate relatively high vibrations or noise (e.g., structural demolition, pile driving) should be perfonned outside of the bat maternity season (April I-August 31). • Foraging and night roosting were observed during the survey. If nighttime work is necessary for project construction, LSA recommends that night lighting shall be used only on the portion of the structure actively being worked on and focused on the direct area of work, and that airspace access to and from the roost features of the structure shall not be obstructed except in direct work areas. • Although no foliage-roosting bat species such as western yellow bat (Lasiurus xanthinus), western red bat (Lasiw-us b/ossevillii), or hoary bat (Lasiurus cinereus) were observed or acoustically detected during the nighttime survey, it is possible that any of these species may roost in the fan palm (Washingtonia sp.), willow (Salix sp.), or eucalyptus (Eucalyptus spp.) trees within the study area because those trees provide suitable roosting habitat for these species. If tree removal or trimming (including palm frond trimming) is necessary for project construction, this activity should be perfonned outside of the bat maternity season (April I-August 31) to avoid potential mortality to flightless young; this time period coincides with the clearing and grubbing restrictions typically associated with bird nesting season. Following the completion of the summer maternity season survey, and as construction plans with regard to the El Camino Real bridge structures are finalized, consultation and communication between engineers and a qualified bat biologist early in the construction planning process will aid in the detennination and finalization of site-and species-specific measures to minimize impacts to bats in a timely, cost-effective, and structurally successful manner. 1,29il6 «P:\HCR1402\Biology1Ba1 Survey\BatNightSurvey_ ElCammoReal docx» 6 l~AASSOi,iAlfS fN<' REFERENCES Erickson, G.
