Methods for delineating wetlands follow guidelines set forth by the U.S. Army Corps of Engineers (USACE; 1987). A total of 2.85 acres of USACE wetlands and non-wetland waters of the U.S. and 12.28 acres of California Department of Fish and Game (CDFG) jurisdictional areas occur on-site. The USACE and CDFG jurisdictional waters eventually connect to the Pacific Ocean, approximately one mile southwest of the site. 1.0 Introduction This report describes the results of a wetland delineation conducted on the 43.6-acre Rancho Milagro study area. This report identifies the location of all jurisdictional waters and provides the necessary background information for analysis by USACE and CDFG. USACE and CDFG can use these data to make a final jurisdictional determination with respect to Section 404 of the Clean Water Act (CWA) and Section 1600-1607 of the Fish and Game Code. Areas that qualify as wetlands under the USACE or CDFG standards are also considered wetlands by the City of Oarlsbad. The existing biological resources on-site, proposed impacts, and mitigation measures are discussed separately in the Revised Biological Technical Report for the Rancho Milagro Study Area, Oarlsbad, California (RECON 2009). The Rancho Milagro property is located in the city of Oarlsbad, California (Figure 1). The site is on an unidentified range, township, and section of the U.S. Geological Service (USGS) San Luis Rey quadrangle (USGS 1997). The site is north of El Oamino Real near the intersection of College Boulevard and El Oamino Real, approximately one mile north of Palomar Airport Road and a half mile east of Sintorosa Country Club (Figure 2). The study area is composed of the 43.57-acre Rancho Milagro property and the adjacent and off-site 0.06-acre section of a sewer line. The Rancho Milagro property is divided into two portions: a 16.30-acre area in the southern portion of the study area that was previously dedicated for mitigation and restoration for the adjacent Terraces at Sunny Creek development and a 27.27-acre upland and riparian area in the remaining northern portion of the study area (Figure 3). Elevation on-site ranges from approximately 80 feet above mean sea level (MSL) in the southwestern portion of the site to 200 feet above MSL in the northeastern portion of the site (USGS 1997). Agua Hedionda Creek flows from east to west along the southern boundary of the site and an unnamed tributary of Agua Hedionda Creek flows from east RECON Page 1 liytCB;;;;;^ Camp j/^ Bonsall Paum Pendteton w Oceansi msidej 78 ' UNINCdPRORATED I } AValley' Jenter Buena Vista Lagoon Agua Hedionda' Lagoon BatiquitosK Lagoon Sar Loveland Reservoir san Lal<e\\ Hodges UN J/fLake I Ramona Rancho Penasquitos Pt Way ' *"[~~' Poyvay Pacific Ocean Carmel Valley San Diego l^irarm Reservoir Project location Miles RECON M:\jobs2\3889-1\common_gis\fig1 .mxd 03/05/07 FIGURE 1 Regional Location Map Source: USGS 7.5 minute topographic map series, SAN LUIS REY quadrangle, Agua Hedionda Land Grants Study Area RECON M:\jobs2\3889-1\common_gis\fig2.mxd 10/14/08 FIGURE 2 Project Location on USGS Map Image source: Copyright 2008 GlobeXplorer, LLC, All Rights Reserved (flown Jan 2008) Feet 350 RECON M:\jobs2\3889-1\common_gis\fig3.mxd 10/14/08 Study Area FIGURE 3 Project Location on Aerial Photograph Revised Wetland Delineation Report for the Rancho Milagro Study Area to west along the northern boundary of the site (see Figures 2 and 3). Currently, the site contains an agricultural operation on the hilltop in the northern half of the site. Undeveloped native vegetation communities occur along the northern boundary and within the southern half of the site. The site is immediately bounded by agricultural development, scattered ranch homes, and patches of undeveloped native vegetation communities (see Figure 3). The site is proposed for the development of residential homes. 2.0 l\/lethods A routine wetland delineation was performed on-site by RECON biologist Darin Busby on October 2, 2003 and April 28, 2004. The wetland delineation was performed according to the guidelines set forth by USACE (1987). A wetland delineation is used to identify and map the extent of the wetlands and waters of the U.S. and provide information regarding jurisdictional issues. Prior to conducting the delineation, an aerial photograph and the USGS Encinitas quadrangle were examined to aid in the determination of potential waters of the U.S. on-site. Once on-site, the potential areas were examined to determine the presence of any wetland parameters. Soil test pits were selected within potential wetland areas and where the apparent boundary between wetland and upland was inferred based on changes in the topography, hydrology, and composition of the vegetation. The remainder of the survey area was also examined in the field for potential USACE non-wetland waters of the U.S. and CDFG jurisdictional areas. The locations of soil test pits and jurisdictional areas were marked on the one- inch-equals-200-feet aerial photograph. Guidelines for delineating the extent of USACE and CDFG jurisdictional areas are described below. Access to Agua Hedionda Creek was limited due to the presence of a dense understory of western poison oak {Toxicodendron diversilobum) and impenetrable vegetation within the southern willow scrub and sycamore/oak woodland. As a result, sample points were limited to only a few select accessible locations. The extent of the jurisdictional areas between sample points was inferred based on observations made where samples were taken. In addition, because the development plan for the Rancho Milagro property limits the proposed development to the northern half of the site, it was not critical that these inaccessible areas along Agua Hedionda Creek be accurately delineated. Gerry Scheid, senior RECON wetland specialist, conducted a site visit on December 14, 2006 to verify and update the existing wetland delineation. The results of this wetland delineation have been incorporated into this revised document. RECON Pages Revised Wetland Delineation Report for the Rancho Milagro Study Area 2.1 USACE Jurisdiction In accordance with Section 404 of the CWA, the USACE regulates the discharge of dredged or fill material into waters of the U.S. The term "waters of the United States" is defined as: • All waters currently used, or used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters subject to the ebb and flow of the tide; • All interstate waters including interstate wetlands; • All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds; the use, degradation, or destruction of which could affect foreign commerce including any such waters: (1) which could be used by interstate or foreign travelers for recreational or other purposes; or (2) from which fish or shell fish are, or could be taken and sold in interstate or foreign commerce; or (3) which are used or could be used for industries in interstate commerce. • All other impoundments of waters otherwise as defined as waters of the United States under the definition; • Tributaries of waters identified above; • The territorial seas; and • Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in the paragraphs above [33 CFR Part 328.3(a)]. Federal regulatory authority only extends to activities that affect interstate commerce pursuant to Article 1, Section 8 of the U.S. Constitution. Prior to 1985, in accordance with the interstate commerce requirement, USACE restricted their jurisdiction on isolated (intrastate) waters, such as ponds or vernal pools lacking connection to waters of the U.S. On September 12, 1985, the Environmental Protection Agency issued a memorandum asserting USACE jurisdiction over isolated waters that are used or could be used by migratory birds or endangered species. This assertion became known as the "Migratory Bird Rule." Consequently, the definition of "waters of the United States" in USACE regulations was modified to include isolated waters that qualified under the Migratory Bird Rule. On January 9, 2001, the Supreme Court of the United States issued a decision on Solid Waste Agency of Northern Cook County vs. United States Army Corps of Engineers et RECON Pagee Revised Wetland Delineation Report for the Rancho Milagro Study Area al. (SWANCC) with respect to whether the use of an isolated, intrastate pond by migratory birds is sufficient interstate commerce to warrant USACE jurisdiction over that pond pursuant to Section 404 of the CWA. The Court held that the Migratory Bird Rule is not a fairly supported interpretation of the term "waters of the United States." By determining that Congress was not intended to regulate isolated wetlands under the CWA, the Supreme Court shifted the regulatory burden to states and local governments. However, the 2001 ruling did not refute the Court's earlier decision in the United States versus Riverside Bayview Homes, Inc. that upheld USACE jurisdiction over wetlands adjacent to navigable waters or express any opinion on the authority of USACE to regulate wetlands that are not adjacent to bodies of open water above and beyond the Migratory Bird Rule. 2.1.1 USACE Wetlands According to the 1987 USACE manual, wetlands are defined as "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 adapted for life in saturated soil conditions." Wetlands are delineated using three parameters: hydrophytic vegetation, wetland hydrology, and hydric soils. According to USACE, indicators for all three parameters must be present to qualify a wetland. The definition of a wetland includes the phrase "under normal circumstances" because there are situations in which the vegetation of a wetland has been removed or altered as a result of recent natural event or human activities (USACE 1987). The majority of the site contains normal circumstances, and a routine delineation method was performed. A small portion of the stream bank along Agua Hedionda Creek does not contain normal circumstances. The vegetation has been removed from the stream bank on the northern side of Agua Hedionda Creek adjacent to the stream crossing in the southwestern portion of the site. The vegetation may have been removed to prevent or reduce the potential for flooding over the road during large storm events. The area most likely previously supported hydrophytic species such as arroyo willow (Salix lasiolepis). Although this area is considered an atypical situation since the vegetation is absent, a routine delineation method was performed by classifying the hydrology and soils present in the area. 2.1.1.1 Hydrophytic Vegetation Hydrophytic vegetation is defined as "the sum total of macrophytic plant life growing in water or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content" (USACE 1987). The potential wetland areas were surveyed by walking the study area and making observations of those areas exhibiting RECON Page 7 Revised Wetland Delineation Report for the Rancho Milagro Study Area characteristics of jurisdictional waters or wetlands. Vegetation within the potential jurisdictional areas was examined. The relative canopy cover of each species present was visually estimated. The dominant species were then recorded on a summary datasheet along with the associated wetland indicator status of those species. The wetland indicator status of each dominant species was determined by using the list of wetland plants for California provided by the U.S. Fish and Wildlife Service (1997). The hydrophytic vegetation criterion is considered fulfilled at a location, if greater than 50 percent of all the dominant species present within the vegetation unit have a wetland indicator status of obligate (OBL), facultative-wet (FAOW), or facultative (FAC) (USACE 1987). An OBL indicator status refers to plants that have a 99-percent probability of occurring in wetlands under natural conditions. A FAOW indicator status refers to plants that occur in wetlands (67-to-99-percent probability) but are occasionally found in non- wetlands. A FAC indicator status refers to plants that are equally likely to occur in wetlands or non-wetlands (estimated probability 34 to 66 percent). 2.1.1.2 Wetland Hydrology Hydrologic information for the study area was obtained by reviewing USGS topographic maps and by directly observing hydrology indicators in the field. Examples of wetland hydrology indicators may include, but are not limited to, inundation, watermarks, drift lines, sediment deposits, and drainage patterns. Evidence of flows, flooding, and ponding was recorded, and the frequency and duration of these events were inferred. The wetland hydrology criterion is considered fulfilled at a location if, based upon the conclusions inferred from the field observations, an area has a high probability of being periodically inundated or has soils saturated to the surface at some time during the growing season to develop anaerobic conditions in the surface soil environment, especially the root zone (USACE 1987). 2.1.1.3 Hydric Soils A hydric soil is a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic vegetation (USACE 1987). The hydric soil criterion is considered fulfilled at a location if soils in the area can be inferred to have a high groundwater table, evidence of prolonged soil saturation, or any indicators suggesting a long-term reducing environment in the upper 18 inches of the soil profile. RECON Page 8 Revised Wetland Delineation Report for the Rancho Milagro Study Area 2.1.2 USACE Non-wetland Jurisdictional Waters The USACE also requires the delineation of non-wetland jurisdictional waters of the U.S. These waters must have strong hydrology indicators such as the presence of seasonal flows and an ordinary high watermark. An ordinary high watermark 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 areas (33 OFR Part 328.3). Areas delineated as non-wetland jurisdictional waters may lack wetland vegetation or hydhc soil characteristics. Hydric soil indicators may be missing, because topographic position precludes ponding and subsequent development of hydric soils. Absence of wetland vegetation can result from frequent scouring due to rapid water flow. These types of jurisdictional waters are delineated by the lateral and upstream/downstream extent of the ordinary high watermark of the particular drainage or depression. 2.2 California Department of Fish and Game Under sections 1600-1607 of the Fish and Game Oode, the CDFG regulates activities that would divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake that supports fish or wildlife. CDFG has jurisdiction over riparian habitats (e.g., southern willow scrub) associated with watercourses. Jurisdictional waters are delineated by the outer edge of riparian vegetation or at the top of the bank of streams or lakes, whichever is wider. 2.3 City of Carlsbad The City of Oarlsbad takes jurisdiction of all USACE and CDFG jurisdictional areas (City of Oarlsbad 2004). 3.0 Results of Field Data A description of the major hydrophytic vegetation units observed, soil types encountered, and a discussion of the hydrology in the survey area is presented below.

Figure 4 illustrates the locations of each vegetation community on-site, and Table 1 lists their acreages. 3.1.1 Wetland/Riparian Vegetation Communities Freshwater marsh, southern willow scrub, sycamore/oak woodland, and mule fat scrub are present on-site. These wetland/riparian vegetation communities contain hydrophytic plant species, as recorded on the wetland data forms (see Attachment 1). Areas with hydrophytic plant species satisfy one of the three criteria necessary to be identified as a USAGE wetland. 3.1.1.1 Freshwater Marsh Freshwater marsh is a vegetation community that occurs in open bodies of fresh water with little current flow, such as ponds, and to a lesser extent around seeps and springs. RECON Pageil Revised Wetland Delineation Report for the Rancho Milagro Study Area All wetland habitats have been greatly reduced throughout their entire range and continue to decline as a result of urbanization. Approximately 0.21 acre of freshwater marsh is present along the unnamed drainage running through the center of the study area (Photograph 1). The dominant plants in this community include cattails {Typha spp.), spiny rush {Juncus acutus ssp. leopoldii), an unidentified rush species {Juncus spp.), California bulrush {Scirpus californicus), and yerba mansa {Anemopsis californica). Cattail, yerba mansa, and California bulrush are OBL plant species, and spiny rush and rush are classified as FAOW plant species. 3.1.1.2 Southern Willow Scrub Southern willow scrub is a dense riparian community dominated by broad-leafed, winter- deciduous trees such as willows {Salix spp.). This vegetation community is typically found along major drainages but also occurs in smaller drainages. The density of the willows typically prevents a dense understory of smaller plants from growing. The representative species typically grow in loose, sandy, or fine gravelly alluvium deposited near stream channels during flood flows. This community requires repeated flooding to prevent succession to community dominated by sycamores and cottonwoods (Holland 1986). Approximately 2.58 acres of southern willow scrub is present along the unnamed drainage running through the center of the study area (see Photographs 1 and 2). The vegetation community is dominated by arroyo willow, which forms a canopy with variable density throughout the study area. Arroyo willow is classified as a FAOW plant species. In some areas understory plant species include spiny rush, saltgrass {Distichlis spicata), common horsetail {Equisetum arvense), and mugwort {Artemisia douglasiana). Spiny rush, saltgrass, and mugwort are FAOW plant species. Common horsetail is a FAC plant species. 3.1.1.3 Sycamore/Oak Woodland Approximately 9.45 acres of sycamore/oak woodland occurs adjacent to Agua Hedionda Creek in the southern portion of the site. The habitat is dominated by coast live oak and western sycamore {Platanus racemosa). Understory plant species include mugwort {Artemisia douglasiana), California rose (flosa californica), western poison oak, fuchsia-flowered gooseberry {Ribes speciosum), coyote bush {Baccharis pilularis), and California blackberry {Rubus ursinus). Western sycamore is classified as a FAOW species, and California rose and California blackberry are classified as FAO+ species.

This vegetation community occurs along drainages with a fairly coarse substrate and a moderate depth to the water table. Mule fat scrub is developed and maintained from flooding or other disturbance, but may change through successlonal processes to willow-cottonwood or sycamore-dominated riparian forest/woodland in the absence of disturbance. The community can also occur where dominant riparian scrubs and woodlands are disturbed or open (Holland 1986). Mule fat scrub is present on approximately 0.04 acre along a dry drainage on the eastern edge of the study area (Photograph 3). This vegetation community is dominated by mule fat, which is classified as a FACW plant species. 3.1.2 Upland Vegetation Communities Diegan coastal sage scrub, disturbed Diegan coastal sage scrub, coast live oak woodland, eucalyptus woodland, disturbed land, agricultural fields, and developed land are present on-site. These vegetation communities are generally considered upland vegetation communities and are described in the biological technical report (RECON 2009). 3.2 Hydrology Several drainages occur on-site. All the drainages on-site have wetland hydrology indicators in the form of standing water, saturated soils, water marks, drift lines, cut banks, sediment deposits, flowing water, and/or topography. All the drainages connect to Agua Hedionda and eventually to the Pacific Ocean, approximately four miles west of the site. Areas with wetland hydrology satisfy one of the three criteria necessary to be identified as a USACE wetland. Agua Hedionda Creek contains water that flows from east to west along the southern boundary of the site. Agua Hedionda Creek is represented as a blue line drainage on the San Luis Rey quadrangle (USGS 1997). The Creek is typically intermittent but can be perennial during high rainfall years. Agua Hedionda Creek passes under a road through four one-foot-wide culverts in the southwestern portion of the property (Photograph 4). Agua Hedionda Creek eventually connects to Agua Hedionda Lagoon and the Pacific Ocean. An unnamed tributary of Agua Hedionda Creek channels intermittent flows from east to west along the northern boundary of the site. This tributary funnels into a pipe at the northwestern corner of the site that eventually connects to Agua Hedionda Creek, which eventually connects to Agua Hedionda Lagoon and the Pacific Ocean. This unnamed RECON Page 14 PHOTOGRAPH 3 Mule Fat Scrub in Northeastern Corner of Site RECON M:\JOBS2\3889\bio\graphics\photo3.ai 06/02/04 PHOTOGRAPH 4 Stream Crossing over Agua Hedionda Creek in Southwestern Portion ofSite RECON M:\JOBS2\3889\bio\graphics\photo4.ai 06/02/04 Revised Wetland Delineation Report for the Rancho Milagro Study Area drainage is not represented as a blue line drainage on the San Luis Rey quadrangle (USGS 1997). Six unnamed ephemeral drainages occur on-site. Four of them in the northern portion of the site connect to the unnamed tributary to Agua Hedionda Creek, Agua Hedionda Lagoon, and the Pacific Ocean. The two other drainages along the eastern boundary and in the southern portion of the site, respectively, do not connect to Agua Hedionda Creek, Agua Hedionda Lagoon, or the Pacific Ocean. These two drainages terminate at the southwestern corner of the site adjacent to the dirt access road. None of these ephemeral drainages contained flowing water at the time of the surveys, but are likely to channel water during times of high precipitation. 3.3 Soils 3.3.1 Soil Maps Seven soil series are present on-site: Altamont clay, 9-to-15-percent slopes; Altamont clay, 15-to-30-percent slopes; Cieneba coarse sandy loam, 5-to-15-percent slopes, eroded; Cieneba-Fallbrook rocky sandy loam, 9-to-30-percent slopes, eroded; Huerhuero loam, 9-to-15-percent slopes; Riverwash; Terrace escarpments; Tujunga sand, O-to-5-percent slopes; Visalia sandy loam, 2-to-5-percent slopes (U.S. Department of Agriculture 1973). Characteristics of these soils are summarized from the U.S. Department of Agriculture (USDA) Soil Survey of San Diego Area, California (USDA 1973) and the local hydric soil list (USDA 1992). The following soils are classified as hydric on the USDA Hydric Soils List (USDA 1992): Riverwash; Tujunga sand, O-to-5-percent slopes; and Visalia sandy loam, 2-to-5-percent slopes. 3.3.1.1 Altamont Series Altamont soils belong to the Vertisol soil order and Typic Chromoxererts subgroup. Vertisol soils are clayey soils more than 20 inches deep that crack to a depth of at least 20 inches. Typic Chromoxererts have a dark-colored surface horizon at least 12 inches thick and no distinct mottles in the uppermost 20 inches of soil material. The top layer of soil is typically dark brown in color, with deeper layers being yellowish-brown to olive- yellow in color. Altamont soils are derived from weathered calcareous shale. Altamont clay soils, 9-to-15-percent slopes, occur in the northeastern and southwestern portion of the site. This soil type is well drained and has a slow permeability, medium runoff, and moderate erosion hazard. RECON Page 17 Revised Wetland Delineation Report for the Rancho Milagro Study Area Altamont clay soils, 15-to-30-percent slopes, occur on the hilltop in the southeastern portion of the site. This soil type typically occurs on rounded hills and has slow permeability, medium-to-rapid runoff, and a moderate-to-high erosion hazard. 3.3.1.2 Cieneba Series Cieneba soils are part of the Entisol soil order and Typic Xerorthents subgroup. Entisol soils and Typic Xerorthents are young soils that show little alteration of the parent material. The color, structure, and texture are similar to the decomposed granite parent rock. The top layer of soil typically is brown in color, with deeper layers that are reddish brown in color. Cieneba coarse sandy loam, 5-to-15-percent slopes, eroded, occurs in the southern portion of the site. This soil type typically occurs on rolling hills and is moderately to excessively drained, has slow-to-medium runoff, rapid to moderately slow permeability, and a slight-to-moderate erosion hazard. Cieneba-Fallbrook rocky sandy loam, 9-to-30-percent slopes, eroded, occurs in the central portion of the site. Typically, this soil group occurs on uplands with over five- percent surface cover of large rock outcrops and boulders. Cieneba-Fallbrook rocky sandy loam soils consist of weathered granitic rock that tend to be excessively drained and have slow-to-medium runoff, rapid permeability, and moderate-to-high erosion hazard. 3.3.1.3 Huerhuero Series Huerhuero loam, 9-to-15-percent slopes, occurs in the northern portion of the site. Huerhuero loam belongs to the Alfisol soil order and Haplic Natrixeralfs subgroup. Alfisol soils have been in place long enough for the movement and accumulation of clays within the soil profile. They characteristically have a massive, hard surface layer and horizons of clay accumulation that have high base saturation. The top layer of soil typically ranges from pale brown to grayish-brown in color, with deeper layers ranging from dark brown to reddish-brown in color. These soils are often enriched with aluminum and iron. Haplic Natrixeralfs have blocky structures in the horizons of clay accumulation. Huerhuero loam soils developed from sandy marine sediments and tend to be well drained, and have medium-to-rapid runoff and moderate-to-high erosion hazard. 3.3.1.4 Riverwash Riverwash occurs in the southwestern portion of the site. Riverwash typically occurs in intermittent stream channels and is a sandy, gravelly, and cobbly substrate. Rivenwash is excessively drained and has rapid permeability. RECON Page 18 Revised Wetland Delineation Report for the Rancho Milagro Study Area 3.3.1.5 Terrace Escarpments Terrace escarpments occur in the southeastern portion of the site. This soil type typically occurs on the coastal plain and as small areas in the foothills and the desert. The soil occurs between narrow floodplains and adjoining uplands, and the steep sides of drainages that are entrenching into level uplands. Typically, there are 4 to 10 inches of loamy or gravelly soil over soft marine sandstone, shale, or gravelly sediments. The soil has rapid runoff and a high erosion hazard. 3.3.1.6 Tujunga Series Tujunga soils are part of the Entisol soil order and Typic Xeropsamments subgroup. Entisol soils are young soils that show little alteration of the parent material. Typic Xeropsamments typically have a clay lamella that is less than 15 inches thick. Tujunga soils are derived from granitic alluvium and are found on alluvial floodplains. Tujunga sand, O-to-5-percent slopes, is excessively drained and has rapid permeability, a slow runoff, and a slight erosion hazard. 3.3.1.7 Visalia Series Visalia soils belong to the Mollisol soil order and Pachic Haploxerolls subgroup. Mollisols and Pachic Haploxerolls have a dark-colored surface horizon that is typically more than 20 inches thick and is high in organic-matter content. Visalia sandy loam, 2-to-5-percent slopes, is well to moderately well drained and has moderate permeability, slow-to- medium runoff, and a slight-to-moderate erosion hazard. 3.3.2 Soils Results Sample points were selected within potential wetland areas and where the apparent boundary between wetland and upland was inferred based on changes in the topography, hydrology, and composition of the vegetation. Twenty-six soil test pits were dug throughout the site (Figures 5A-5D). Soil test pits 1, 3, 5, 7, 9, 12, 13, 17, 18, 21, 23, and 24 contained definitive hydric soils (see Attachment 1). 4.0 Wetland Delineation Approximately 2.85 acres of USAGE jurisdictional areas and 12.28 acres of CDFG jurisdictional areas occur within the study area (Table 2). These jurisdictional areas are illustrated in Figures 5A-5D and presented in Table 2. USAGE and CDFG will evaluate this wetland delineation during the permit review process to make a final jurisdictional determination with respect to Section 404 of the OWA and Section 1600-1607 of the Fish and Game Oode.

This will need to be verified by these agencies during the permitting process. 4.1 U.S. Army Corps of Engineers A total of 2.85 acres of USAGE jurisdictional areas occurs within the study area (1.19 acres of USACE wetland and 1.66 acres of USACE non-wetland waters of the U.S). USACE wetlands occur within Agua Hedionda Creek in the southern portion of the site and the unnamed tributary of Agua Hedionda Creek in the northern portion of the site. The wetlands along Agua Hedionda Creek most likely formed as sediment and debris flowing downstream collected and formed banks that eventually were able to support wetland vegetation and develop hydric soils. USACE wetlands occur within the following vegetation communities in the study area: freshwater marsh, southern willow scrub, and mule fat scrub. USACE non-wetland waters of the U.S. occur within Agua Hedionda Creek where there is frequent scouring due to rapid water flow and within the drainages leading into the unnamed tributary in the northern portion of the site. USACE non-wetland waters of the U.S. occur within the following vegetation communities in the study area: southern willow scrub, disturbed coastal sage scrub, and disturbed lands. The presence of wetland hydrology, hydrophytic vegetation, and hydric soils was used to identify each USACE wetland. The presence of an ordinary high water mark was used to identify each USACE non-wetland waters of the U.S. All the USACE wetlands and USACE non-wetland waters of the U.S identified have a connection off-site and eventually connect to the Pacific Ocean. RECON Page 25 Revised Wetland Delineation Report for the Rancho Milagro Study Area 4.2 California Department of Fish and Game A total of 12.28 acres of CDFG jurisdictional areas occur within the study area (12.21 acres of CDFG riparian areas and 0.07 acre of CDFG streambed). CDFG jurisdictional areas are delineated by the outer edge of riparian vegetation or at the top of the bank of streams or lakes, whichever is wider. CDFG riparian areas occur within and adjacent to Agua Hedionda Creek in the southern portion of the site and within and adjacent to the unnamed tributary of Agua Hedionda Creek in the northern portion of the site. CDFG riparian areas occur within the following vegetation communities on-site: freshwater marsh, southern willow scrub, sycamore/oak woodland, and mule fat scrub. CDFG streambeds occur within the drainages leading into the unnamed tributary in the northern portion of the site and within and isolated drainage along the eastern boundary of the site. CDFG streambeds occur within the following vegetation communities on-site: southern willow scrub, disturbed lands, and disturbed and undisturbed coastal sage scrub. 4.3 City of Carlsbad All USACE and CDFG jurisdictional areas fall under the jurisdiction of the City of Oarlsbad. City of Oarlsbad jurisdictional areas total 12.28 acres. 5.0 Regulatory Issues USACE and CDFG jurisdictional areas are regulated by the federal and state governments under a no-net-loss policy, and all impacts are considered significant and should be avoided to the greatest extent possible. Unavoidable and approved impacts would require mitigation through habitat creation, enhancement, or preservation, as determined by a qualified restoration specialist in consultation with the regulatory agencies. In addition, regulatory agencies often require that a buffer be maintained between jurisdictional waters and any development. The width of the buffer area can vary, depending on project design, but is typically 100 feet from the edge of the jurisdictional area. Any impacts to USACE and CDFG jurisdictional waters would require a 404 permit from USAGE, a 401 Water Quality Certification from the Regional Water Quality Oontrol Board, and a 1603 Streambed Alteration Agreement from CDFG. The biological technical report prepared for the proposed project (RECON 2007) contains additional biological resource information and proposed impacts and mitigation for the site.
