1 PROJECT DESCRIPTION
Dockweiler Road is proposed to be extended to Railroad Avenue in Newhall. The road extension includes a bridge over Newhall Creek, a tributary of the Santa Clara River.
The project is located in an un-numbered section of Township 4 North, Range 16 West, of the U.S. Geological Survey (“USGS”) Newhall 7.5’ quadrangle (Figure 1).
Newhall Creek is at an elevation of about 1,264 feet above mean sea level at the bridge location.
The Project will require notification to State and Federal agencies with jurisdiction over stream resources. However, the potential disturbance area for bridge construction is not known at this time. The purpose of this Delineation is to describe the limits of State and Federal jurisdiction within 200 feet upstream and downstream of the bridge location.
2 METHODS
2.1 Document Review
Site-Specific Data. A desktop analysis of potential jurisdictional features was conducted for guidance in the field, based on the USGS topographic map of the project area and aerial photographs. Soil survey data available from the National Cooperative Soil Survey (USDA-NRCS) were not used because these data are not intended to be used at the fine scale of this project.
Delineation Protocols. Documents consulted for delineation of Federal jurisdiction consisted of Lichvar and McColley (2008) regarding identification of “ordinary high water mark” in arid regions, the U.S. Army Corps of Engineers (USACE) guidelines for interpretation of Federal jurisdiction following the Rapanos, Carabell, and SWANCC decisions (USACE, 2007; USACE and EPA, 2007), the USACE 1987 Wetland Delineation Manual (Environmental Laboratory, 1987), and USACE guidelines and forms for jurisdictional determination in the arid southwest (USACE, 2001, 2008). Delineation of California State jurisdiction (CDFW and RWQCB) was based on definitions and regulations specified by Sections 1600-1616 of the Fish and Game Code, Title 14 of the California Code of Regulations, and Section 13050 of the California Water Code.
JD – Dockweiler Bridge
2.2 Field Survey
A field survey of the site was conducted by Edith Read on June 17, 2013. Site features were assessed for indicators of stream, riparian, or wetland functions. Indicators of stream functions, particularly surface flows, typically include a clearly defined bed and bank structure, bank shelving, deposits of organic debris, cracked mud or clay, and/or water marks on rocks or soil. Indicators of wetland functions typically include wetland or riparian vegetation, and/or soils with anaerobic, redoxymorphic, or hydric features. Plant taxonomy followed the current flora for California (Baldwin et al., 2012). Plant community designations for indigenous vegetation types were based on Sawyer et al. (2009). Determination of the wetland occurrence rating of plant species was based on the 2012 ratings for the Arid West Regional Supplement (USACE, 2012).
2.3 Delineation Criteria
CDFW
At the State level, the California Department of Fish and Wildlife (CDFW; formerly CDFG) has jurisdiction over rivers, streams, and lakes.1 The California Code of Regulations defines a stream as “a body of water that flows at least periodically or intermittently through a bed or channel having banks and supports fish and other aquatic life including watercourses having a surface or sub surface flow that supports or has supported riparian vegetation.”2 CDFW jurisdiction typically extends between the top of each bank or to the outer edge of contiguous riparian vegetation, whichever is greater.
For this project, limits of CDFW jurisdiction within the potential work area were drawn to the tops of the levees on both sides of Newhall Creek.
USACE
At the Federal level, the USACE regulates placement of “dredge” and “fill” in waters of the U.S. including adjacent wetlands under the authority of Section 404 of the Clean
1 Fish & Game Code §§ 1600 – 1616
2 California Code of Regulations (C.C.R.), Title 14 § 1.72 JD – Dockweiler Bridge
Water Act.3 The Code of Federal Regulations defines “waters of the U.S.” as intrastate lakes, rivers, streams, mudflats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds. Wetlands are defined as “areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions.” Assessment of Federal jurisdiction is based on two main factors: 1) nexus or connectivity to “traditionally navigable waters” or “relatively permanent waters”; and 2) presence of “ordinary high water marks.”
RWQCB
Federal authority over water quality under Section 401 of the Federal Clean Water Act is typically delegated to regional water quality control boards unless a project encompasses more than one region, in which case the State Water Resources Control Board may assert regulatory authority. The current Project falls under the authority of the Los Angeles Regional Water Quality Control Board. Section 401 of the Clean Water Act requires that “any applicant for a Federal permit for activities that involve a discharge to Waters of the U.S., shall provide the Federal permitting agency a certification from the State in which the discharge is proposed that states that the discharge will comply with the applicable provisions under the Federal Clean Water Act.”
In addition to Section 401 of the Federal Clean Water Act, the RWQCB exerts authority over “Waters of the State” and water quality by means of State law. “Waters of the State” are broadly defined by sections of the California Water Code, known as the Porter-Cologne Water Quality Control Act, as “any surface water or groundwater, including saline waters, within the boundaries of the state.”4 As of this writing, the State Water Resources Control Board is considering adoption of a Wetland Area Protection Policy and regulations governing the discharge of dredge or fill material into waters of the State that would apply at State and regional levels
3 Clean Water Act of 1972 § 404. See also 33 U.S.C. § 1341 4 California Water Code § 13050(e)
JD – Dockweiler Bridge
(California State Water Resources Control Board, 2013). This policy is intended to improve consistency in the definition of a wetland and regulatory mechanisms affecting wetland protection, and an approach for collecting and tracking aquatic resource monitoring data. One difference between existing regulations and the new policy is in the definition of a wetland, wherein wetland vegetation does not have to be present for a feature to qualify as a wetland. Specifically, an area is defined as a wetland if, under normal circumstances: 1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or shallow surface water, or both; 2) the duration of such saturation is sufficient to cause anaerobic conditions in the upper substrate; and 3) the area either lacks vegetation or the vegetation is dominated by hydrophytes. This definition is adopted here in anticipation of the new regulations.
3 RESULTS AND DISCUSSION
Figure 2 shows topography of the region, and Figure 3 shows photographs representing the project site. Figure 4 shows vegetation and jurisdictional features in the survey area.
3.1 Watershed Connectivity, Geomorphology and Hydrology There are two jurisdictional features at the project location:
1. Newhall Creek, upstream of its confluence with Placerita Creek and the south fork of the Santa Clara River. This creek is mapped by the USGS as a “blue-line” intermittent stream. The direction of creek flow is from southeast to northwest.
Banks of the creek are nearly vertical, with the south bank containing artificial fill (pieces of concrete and asphalt). Railroad tracks and Railroad Avenue are to the west, beyond the top of the bank. Areas immediately east of the creek are vacant except for an industrial yard northeast of the proposed bridge location.
No surface water was present during the June survey, but sparse vegetation cover within the channel indicates frequent scour during the rainy season.
Therefore this feature is best described as an intermittent riverine, relatively permanent water (“RPW”) that has seasonal continuous flow and is tributary to the Santa Clara River, which flows into the Pacific Ocean, a traditionally navigable water (“TNW”). Vegetation and surface features indicate that seasonal JD – Dockweiler Bridge
flows migrate across the entire width of the channel, which averages 35 feet in width at the base (Federal jurisdiction). The distance between the tops of the banks (limits of State jurisdiction) averages 100 feet.
No indicators of prolonged water saturation or ponding, such as surface mud cracks, were observed during the survey.
2. Un-named ephemeral tributary to Newhall Creek. This narrow tributary is about 3.5 feet in width at its base (Federal jurisdiction) and is entirely within State jurisdiction over Newhall Creek. It is assumed that flow enters the project area from a culvert underneath the railroad tracks and Railroad Avenue – this could not be confirmed during the survey due to presence of a homeless camp at the presumed culvert location. The distinct bed and bank structure of this feature, and regional topography shown prior to extensive development in the area, indicate that it is more than just a gully resulting from localized erosion.
Wetland indicators are absent from this feature.
3.2 Vegetation
The following vegetation types occur within the survey area. Of these types, only the narrow-leaf willow thicket is a wetland indicator (Salix exigua – FACW). This vegetation is discussed in more detail below.
Active Channel
Vegetation is sparse within the active channel. The most common species are not wetland indicators. They include scalebroom (Lepidospartum squamatum -- FACU) and mulefat (Baccharis salicifolia – FAC).
Narrow-Leaf Willow Thicket
Narrow-leaf willows (Salix exigua – FACW) occur in a small stand (25 ft x 12 ft) within the alignment of the proposed bridge. While this species is a wetland indicator, other wetland indicators are absent. The vegetation occurs on the opposite side of Newhall Creek from the ephemeral tributary, and likely receives periodic dry-season runoff from streets to the west. We conclude that this thicket is probably not a jurisdictional JD – Dockweiler Bridge
wetland at the Federal level, and is not a jurisdictional wetland at the State level. See Section 3.4 for additional discussion.
Scrub Vegetation
Scrub vegetation consists of scalebroom, mulefat, California sagebrush (Artemisia californica -- NI), and buckwheat (Eriogonum fasciculatum -- NI) in a range of densities on slopes above the active channel of Newhall Creek. None of these species are wetland indicators.
Trees
Three native trees occur adjacent to the northwest boundary of the survey area, about 200 feet northwest of the bridge location. Two of the trees are large California live oaks (Quercus agrifolia – NI) with trunk diameters ranging from four inches to two feet. The third tree is an elderberry (Sambucus nigra – FAC) and located under the oak canopy.
Small groves of exotic trees (tentatively identified as locust – Robinia sp.) occur on the west side of Newhall Creek along the railroad right-of-way.
3.3 Soil
Soil was evaluated at one location under the canopy of the narrow-leaf willow thicket.
Figure 4 shows a photograph of the test pit. Below the litter, two stratified layers are visible, consisting of rock/cobble/sand in the first 12 inches, then six inches of sand down to the base of the pit. This sand layer changes in color, value, and chroma from light gray (5YR 7/1) to black (5YR 2.5/1) toward the bottom of the test profile. No odor was detected during sampling. While a few of the coarse fragments in the upper part of the profile had some faint orange streaks (5YR 5/8) indicative of reducing conditions, these features were not dominant.
3.4 Wetland Determination
3.4.1 Federal
The hydrology and soils of the survey area (floodplains/gravel bars and sand) are naturally problematic for wetland delineation. The following paragraphs include JD – Dockweiler Bridge
excerpts (in italics) from the Arid West supplement (USACE 2008, page 98) of the wetland determination procedure for problematic sites where soils may meet the definition of a hydric soil but do not exhibit typical indicators. Our observations are described for each step of the procedure.
1. Verify that one or more indicators of hydrophytic vegetation are present or that the vegetation is disturbed or problematic. If so, proceed to step 2. Site observations: Narrow-leaf willow has an indicator ranking for the Arid West of Facultative Wetland. Therefore hydrophytic vegetation is present.
2. Verify that at least one primary or two secondary indicators of wetland hydrology are present or that indicators are absent due to disturbance or other factors. If so, proceed to step 3. If indicators of hydrophytic vegetation and/or wetland hydrology are absent, then the area is probably non-wetland and no further analysis is required. Site observations: no primary indicators of wetland hydrology are present. Only one secondary indicator of wetland hydrology (dominance of FACW vegetation) is present.
Based on this information, and the observation that redoximorphic soil features are sparse and (where present) faintly expressed, we conclude that the willow thicket (300 square feet or 0.007 acre) is probably not a Federally jurisdictional wetland. Unfortunately, the Arid West procedure does not allow for a more definitive conclusion.
3.4.2 State
According to the wetland definition under review at the State level, we conclude that the narrow-leaf willow thicket would not meet this definition. While narrow-leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions.
3.5 Non-Wetland Jurisdiction
The proposed bridge will impact Newhall Creek, in a section of the creek that is classified as riverine and relatively permanent water, with continuous flow at least seasonally. The bridge may also impact a narrow, ephemeral tributary to Newhall JD – Dockweiler Bridge
Creek. The extent of permanent and temporary construction impacts need to be known in order to provide a more precise analysis of impacts. 4 RECOMMENDATIONS
The narrow-leaf willow thicket, occupying 300 square feet (25 linear feet and 0.007 acre) within the bridge footprint, could not be definitely concluded to be a wetland using Federal jurisdictional delineation procedures. The only conclusions that could be reached are that the willow thicket is “probably” a non-wetland under Federal criteria, and is not a wetland under State criteria. Given the uncertainty at the Federal level, we recommend the following:
1. Disclosure of the uncertain determination when applying for a permit under the Clean Water Act; and
2. If the bridge project is delayed for more than one year from the date of this report (i.e. beyond 2014), consider one or both of the following two actions: a) re-evaluate the wetland status of the willow thicket site in the field, using evaluation procedures for problematic sites specified in the Arid West manual (USACE 2008), with special focus on soils; and/or b) to avoid a possible permitting issue, assume the willows constitute a wetland and mitigate accordingly.

A. TNWs AND WETLANDS ADJACENT TO TNWs: DO NOT OCCUR WITHIN PROJECT LIMITS
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below.

B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are “relatively permanent waters” (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4.
7 Supporting documentation is presented in Section III.F. 22 A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law.
If the waterbody8
is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below.

C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: .

RE: Proposed Lyons Avenue/Dockweiler Drive Extension Project Dear Ms. Zimmermann,
As per your request received on September 20, 2013, a records search was conducted for the above referenced project. The search includes a review of all recorded archaeological sites within a ½-mile radius of the project site as well as a review of cultural resource reports on file. In addition, the California Points of Historical Interest (SPHI), the California Historical Landmarks (SHL), the California Register of Historical Resources (CAL REG), the National Register of Historic Places (NRHP), and the California State Historic Resources Inventory (HRI) listings were reviewed for the above referenced project site. The following is a discussion of the findings.
Due to the sensitive nature of cultural resources, archaeological site locations are not released.
Newhall, CA USGS 7.5’ Quadrangle
ARCHAEOLOGICAL RESOURCES:
No archaeological sites have been identified on our maps within a ½-mile radius of the project site. No sites are located within the project site. This does not preclude the potential for archaeological sites to be identified during project activities. Two isolates (19-100340, 19-100503) have been identified within a ½-mile radius of the project site. No isolates are located within the project site.
HISTORIC BUILT-ENVIRONMENT RESOURCES:
Fourteen above-ground historic resources (19-180765, 19-187086, 19-187092, 19-188109, 19-188269, 19-188598, 19-188599, 19-188600, 19-188601, 19-188602, 19-188603, 19-188604, 19-188605, 19-188606) have been identified on our maps within a ½-mile radius of the project site. No above-ground historic resources are located within the project site.
ADDITIONAL CULTURAL RESOURCE LISTINGS:
The California Historic Resources Inventory (HRI) lists thirty-one properties that have been evaluated for historical significance within a ½-mile radius of the project site (see enclosed list). These are additional resources that are listed in the Historic Properties Data file and are located either within the project site or within the search radius.
The California Point of Historical Interest (SPHI) of the Office of Historic Preservation, Department of Parks and Recreation, lists no properties within a ½-mile radius of the project site.
The California Historical Landmarks (SHL) of the Office of Historic Preservation, Department of Parks and Recreation, lists no properties within a ½-mile radius of the project site.
The California Register of Historical Resources (CAL REG) lists no properties within a ½-mile radius of the project site. These are properties determined to have a National Register of Historic Places Status of 1 or 2, a California Historical Landmark numbering 770 and higher, or a Point of Historical Interest listed after 1/1/1998.
The National Register of Historic Places (NRHP) lists no properties within a ½-mile radius of the project site.
HISTORIC MAP REVIEW
Santa Susana, CA (1903 & 1941) 15’ USGS - indicated that in 1903, there was a significant amount of development within the project site. The project site was located within a dense urban environment with numerous roads and buildings present.
The Southern Pacific Railroad (San Francisco & New Orleans Line) and Newhall Creek both ran through the project site. Placerita Creek ran to the north of the project site and historic place names nearby included Newhall and Elayton. In 1941, the project site was still located within a dense urban environment with several roads and buildings present in the project site. There was one school present within the vicinity of the project area and all other previously mentioned features still remained.
PREVIOUS CULTURAL RESOURCES INVESTIGATIONS:
Twenty-four studies (LA274, LA834, LA852, LA856, LA984, LA1153, LA3289*, LA3644, LA3661, LA3690*, LA3731*, LA5844*, LA6860, LA7167, LA8129, LA8255*, LA8785, LA8958*, LA9422, LA9867*, LA10405, LA10642*, LA11985, LA12200) have been conducted within a ½-mile radius of the project site. Of these, eight are located within the project site. There are eleven additional investigations located on the Newhall, CA 7.5’ USGS Quadrangle that are potentially within a ½-mile radius of the project site. The reports are not mapped due to insufficient locational information. (* = Located within the project site)
RECOMMENDATIONS
Significant portions of the project site have not been previously surveyed for archaeological resources. Therefore it is recommended that a Phase-I archaeological survey be conducted in areas unobstructed by urban development within the project footprint and area of potential effect. It is also recommended that any previously unidentified historic properties (45 years and older) be recorded, and evaluated for local, state, or national significance prior to the approval of project plans. Finally, the Native American Heritage Commission should be consulted to identify if any additional traditional cultural properties or other sacred sites are known to be in the area.
The professional consultant you retain may request the records search map, archaeological site records, and bibliography from the Information Center referencing the SCCIC number listed above for a fee (per the fee schedule). For your convenience, you may find a professional consultant* at www.chrisinfo.org.

Attn: Mariana Zimmermann, Assistant Environmental Planner re: Paleontological Resources for the proposed Lyons Avenue / Dockweiler Drive Extension Project, in the City of Santa Clarita, Los Angeles County, project area Dear Mariana:
I have conducted a thorough search of our Vertebrate Paleontology records for the proposed Lyons Avenue / Dockweiler Drive Extension Project, in the City of Santa Clarita, Los Angeles County, project area as outlined on the portion of the Newhall USGS topographic quadrangle map that you sent to me via e-mail on 20 September 2013. We do not have any fossil vertebrate localities that lie directly within the boundaries of the proposed project area, but we do have localities nearby from the same sedimentary deposits that occur within the proposed project area.
Surficial deposits in most of the proposed project area, the less elevated portion, consist of younger Quaternary gravels or sands associated with the Newhall Creek that borders on the south and west and the Placerita Creek that flows through the northern part of the proposed project area. Both of these drainages flow into the Santa Clara River just to the northwest of the proposed project area. These deposits usually do not contain significant vertebrate fossils, at least in the uppermost layers. In the more elevated terrain in the southeastern portion of the proposed project area, however, there are dissected older Quaternary fluvial and fan deposits as well as exposures of the terrestrial Pliocene Saugus Formation. These deposits may also occur at depth in the proposed project area. We have no fossil vertebrate localities nearby from the younger Quaternary alluvial deposits. Our closest vertebrate fossil localities from the Saugus Formation, or possibly the older Quaternary sediments, are LACM 6803-6804, directly north of the proposed project area in Saugus south of Bouquet junction on the east side of Bouquet Canyon Road, that produced fossil specimens of camel, Camelidae, and horse, Equus.
Shallow excavations in the younger Quaternary alluvial deposits found at the surface in the less elevated portions of the proposed project area probably will not encounter significant fossil vertebrate remains. Deeper excavations that extend down into older Quaternary deposits or any excavation in the Saugus Formation, however, may well uncover significant vertebrate fossils. Any substantial excavations in the proposed project area, therefore, should be monitored closely to quickly and professionally recover any fossil remains while not impeding development. Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations.
This records search covers only the vertebrate paleontology records of the Natural History Museum of Los Angeles County. It is not intended to be a thorough paleontological survey of the proposed project area covering other institutional records, a literature survey, or any potential on-site survey.
Sincerely,
Samuel A. McLeod, Ph.D.

EIR-Level Review of the Road Alignments for Dockweiler Drive and Lyons Avenue
Project: Dockweiler Road Extension to Lyons Avenue Including the New Lyons Avenue Crossing over the Railroad Tracks
Newhall Area
City of Santa Clarita, California
References: At end of text
Dear Mr. Nazarian:
This preliminary geologic and geotechnical evaluation report of the project site presents has been prepared for incorporation into an Environmental Impact Report (EIR) for the proposed improvements for the extension of Dockweiler Drive and the Lyons Avenue railroad crossing. This report summarizes our opinions regarding the geologic and geotechnical conditions at the above-referenced project site and their effects on the proposed improvements.
1.0 PROPOSED PROJECT
The proposed project consists of future road alignments for extension of Lyons Avenue from its current northeastern terminus at Railroad Avenue to a future intersection with proposed Dockweiler Drive approximately 600 ft. to the northeast. This includes a proposed at-grade crossing over the existing Southern Pacific railroad tracks and a crossing over Newhall Creek using a box culvert to connect to the proposed extension of Dockweiler Drive. Dockweiler Drive is proposed to extend from a point of connection at the Master’s College property boundary northwesterly for approximately 2,000 feet to the intersection of Arch Street and 12th Street. Aden Avenue is to extend from its current southerly terminus to intersect with the future Dockweiler Drive approximately 250 ft. to the south. 27825 Smyth Drive, Valencia, California 91355 661-294-0065 FAX 661-294-0833 Hall and Foreman, Inc.

3.0 SITE DESCRIPTION
The project site is located in the downtown Newhall area of the City of Santa Clarita. The proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The majority of the proposed road alignment for Lyons Avenue traverses undeveloped land, except for areas where artificial fill and railroad ballast have been placed to elevate and support the existing railroad double tracks. Dumped fill with abundant blocks of asphalt and concrete and other miscellaneous debris has been placed on the southwest bank of Newhall Creek, just northeast of the proposed at-grade railroad crossing. The proposed road alignment of Dockweiler Drive also traverses undeveloped land and a storage yard utilized by Los Angeles County Department of Public Works. The site is covered with light to moderate growth of natural grasses and chaparral. Details of the site topography are shown on the base map used for the Geologic Map (see Plate I). Elevations at the site range from approximately 1255 to 1370 ft above mean sea level.

4.0 GEOLOGIC AND GEOTECHNICAL CONDITIONS
4.1 Geologic Setting
The site is located within the central part of the Transverse Ranges geomorphic province of southern California, in the eastern portion of the Ventura Basin. The Ventura Basin has been tectonically down-warped in the geologic past to produce a large-scale synclinal structure in which a thick sequence of Cenozoic sediments has accumulated. In the vicinity of the proposed road alignments, much of the hillside area along the northeastern margin of Newhall Creek consists of bedrock of the Quaternary-age Pacoima Formation (Qp). The relatively flat flood plain southwest of Newhall Creek is underlain by subhorizontal alluvium deposited (Qal). The Pacoima Formation and alluvial deposits are underlain by bedrock of the Plio-Pleistocene, nonmarine Saugus Formation (TQs). No faults or folds have been identified at the project site on the referenced published geologic map of the area. A Geologic Overview Map (see Figure 2) based on Geologic Map of the Newhall Quadrangle (Dibblee, 1996) is provided at the end of this report.
4.2 Geologic Structure
The natural slopes at the project site are underlain by sub-horizontally bedded Pacoima Formation in erosional unconformable contact over Plio-Pleistocene non-marine sediments of the Saugus Formation. The Saugus Formation in the vicinity of the subject site generally strikes roughly east to west and dips gently to the north (Treiman, 1987; and Dibble, 1996).
The Saugus Formation bedding measured in northern bank of the Newhall Creek strikes N70W and dips 5° north. The measured bedding is generally consistent with regional geologic maps and the geologic structure as documented during a previous investigation and published report (see references).
4.3 Geologic Units
The Geologic Map (see Plate I) enclosed in the Appendix of this report illustrates the approximate limits of exposed geologic units based on field observations and the referenced published geologic maps. Artificial fill and railroad ballast have been placed below the railroad tracks. Pavement and aggregate base have been placed beneath existing roadways. General descriptions of geologic units provided below are based the prior geologic observation in the vicinity of the project site, and the exposures in the banks of Newhall Creek in the vicinity of the proposed box culvert.

4.3.1 Saugus Formation (TQs)
Bedrock of the Plio-Pleistocene-age Saugus Formation (TQs) is exposed along the lower portion of the northerly eroded bank of Newhall Creek, just east of the proposed road alignment. The Saugus Formation sediments consist dominantly of gray to light brown sandstone and conglomeratic sandstone with scattered greenish-gray siltstone and silty sandstone (Treiman, 1987). Bedding within the Saugus Formation varies from predominately massive and indistinct to cross-bedded to locally well-developed planes on lensing, fine-grained units. Local variance in bedding orientations is common and is due to cross bedding and/or channelized (erosional) contacts.
4.3.2 Pacoima Formation (Qp)
Bedrock of the Quaternary-age Pacoima Formation (Qp) mantles the majority of the hillside area along the northern margin of Newhall Creek. This formation has been designated as “Older Dissected Surficial Sediments or Qog” after Dibblee, 1996; however, these terrace deposits have been assigned to the Pacoima Formation (of Oakeshott, 1958) by Treiman (CDMG, 1987). For this report, the nomenclature by Treiman is used.
The bedrock generally consists of lensing, crudely stratified, light yellowish-brown to yellowish-brown to brown, silty to clayey, fine- to coarse-grained sandstone with some gravel, cobbles and rare boulders. Bedding is generally crude to locally well defined.
Generally the bedrock is concealed by a mantling of soil and colluvium. However, the eroded banks of the Newhall Creek expose unweathered bedrock.
4.3.3 Quaternary Alluvium (Qal)
Quaternary Alluvium (Qal) underlies the existing surficial artificial fill materials located westerly of Newhall Creek south of 12th Street, and easterly of Newhall Creek north of 12th Street. Based on data obtained by this firm for the adjacent Old Town Newhall Library site, the alluvium is anticipated to consist of interbedded layers of poorly graded sand, silty sand, and gravelly sand. Interbedded layers of sandy silts and clays may also be present. These materials are typically medium dense to dense in the upper 30 to 40 ft. with locally loose conditions in the upper 10 ft.
4.3.4 Recent Stream Channel Deposits (Qsc)
Quaternary Stream channel deposits (Qsc) are located within the active Newhall Creek channel. These deposits consist of recent alluvium that has been reworked due to heavy runoff during periodic rains. Stream channel deposits are very similar to the Quaternary alluvium and generally consist of silty sands, sands, and gravels with cobbles.

October 17, 2014 Page 6
4.3.5 Quaternary Colluvium (Qc)
Colluvium (Qc) is a non-bedded, heterogeneous accumulation of soil and weathered bedrock deposited by gravity on all but the steepest slopes. These deposits have been mapped based on review of the topography where the estimated thickness is greater than about 3 feet.
4.3.6 Artificial Fill (af)
Artificial fill (af) was apparently placed below the existing railroad tracks to elevate the tracks above the Newhall Creek Flood Plain. The engineering characteristics of this material are currently unknown.
4.3.7 Dumped Fill (df)
Dumped fill (df) is present along the active stream margins of Newhall Creek at the vicinity of the proposed Lyons Avenue road alignment. The dumped fill consists of fill soils with abundant debris (asphalt, concrete, construction trash, metal, vehicle tires).
Also present near the proposed alignment is an abandoned vehicle that is partially buried.
4.3.8 Railroad Ballast
Railroad ballast consisting of crushed natural rock was placed to support and elevate the two sets of railroad tracks at the site.
4.4 Landslides
Review of the referenced published geologic maps indicates that no landslides have been mapped at or adjacent to the site. Review of aerial photographs lack geomorphic features that would indicate prior landslide movement.
4.5 Ground Water
Review of historic ground water data from the Seismic Hazard Map for the Newhall Quadrangle, Water-Resources Investigation using Analog Model Techniques in the Saugus-Newhall Area (Robson, 1972), and Los Angeles Flood Control District (LACFCD) water well records indicates that historic high ground water levels are between 75 and 100 ft. below the existing surface at the project site. The locations of nearby water wells are shown on the Water Well Location Map (see Figure 2) and the historic ground water levels for each well obtained from LACFCD records are provided in Summary of LAFCD Water Well Data (see Table 1). In addition, ground water was not encountered in subsurface explorations performed by this firm to a depth of 50 ft in the alluvium for the adjacent Old Town Newhall Library. However, temporary perched ground water Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 7
conditions may exist below Newhall Creek following periods of significant rainfall and runoff.
A low potential exists for temporary, perched ground water conditions to develop within the bedrock of the Pacoima formation. Perched ground water can contribute to slope instability in natural slopes and cut slopes. To prevent build-up of water, subdrains are typically recommended in canyon areas in which fill will be placed and back drains for slopes that are to be constructed as Stability Fills or Buttress Fills.
Due to the historic high ground water elevations and the elevated nature of portions of the road alignment, ground water is not expected to significantly affect the project, provided the proposed grading is evaluated from a geotechnical standpoint during the design stage and the geotechnical recommendations are implemented during construction.
5.0 POTENTIAL CONSTRAINTS, IMPACTS, AND MITIGATION OPTIONS
5.1 Seismic Considerations
5.1.1 Introduction
The subject site lies within the seismically active southern California region.
Earthquake-related hazards typically include ground rupture, ground shaking, and ground failure.
5.1.2 Ground Rupture
Review of the Alquist-Priolo Earthquake Fault Zone Map for the Newhall Quadrangle, the Seismic Safety Element of the L.A. County General Plan, and the published Geologic Maps referenced at the end of this report indicates that no active or potentially active faults traverse the project site. Review of the site topography and the aerial photographs listed at the beginning of this report did not reveal any lineaments or other indicators suggestive of faulting at the site. The nearest known active fault is the San Gabriel Fault, which is 3.7 km from the site at its nearest point (see Table 2 for a list of regional faults near the site and Figure 3 for a map of the fault locations). Therefore, the probability of fault-related ground rupture at the site is considered to be very low.
5.1.3 Ground Motion
Peak ground acceleration (PGA) consistent with maximum considered earthquake (MCE) ground motions were evaluated at the site for bedrock (Site Class B) and alluvial (Site Class C) soil conditions in accordance with the 2013 California Building Code and ASCE 7-10. The mapped MCE geometric mean (MCEG) peak ground accelerations Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 8
(PGAM) adjusted for Site Class effects were first evaluated using the U.S. Seismic Design Maps web tool provided by the United States Geological Survey (USGS). The MCEG PGAM was then evaluated for a 2 percent probability of exceedance within a 50- year period using the USGS 2008 Interactive Deaggregation web tool. The PGAM calculated using the probabilistic procedure is based on estimated values of shear wave velocity (Vs30) within the range designated for the corresponding Site Class. The estimated PGAM for bedrock (1.10g) and alluvial (1.03g) soil conditions was taken as the lesser of the mapped geometric mean peak ground accelerations and the probabilistic geometric mean peak ground accelerations indicated in the table below.

Alluvium D 270 1.10g 1.03g
5.1.4 Ground Failure
Ground failure is a general term for seismically induced, secondary, permanent ground deformation caused by strong ground motion. This includes liquefaction, lateral spreading, ground lurching, seismic settlement of poorly consolidated materials (dynamic densification), differential materials response, sympathetic movement on weak bedding planes or non-causative faults, slope failures, and shattered ridge effects.
The majority of the project site is underlain by bedrock materials that are not susceptible to liquefaction. The alluvial soils present the site (see Geologic Map, Plate I) are not designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potentially liquefiable materials is required. The depth to historic high ground water at the site is greater than 50 ft. Based on the preceding factors, the potential for liquefaction and associated seismic settlements and lateral spreading is therefore considered very low.
Relatively loose granular alluvial soils located within and adjacent to the active Newhall Creek channel and within minor tributary canyons adjacent to the road alignment may be prone to dynamic densification as a result of future earthquake shaking. Evaluation of the potential for dynamic densification should be performed at the design stage.
Typically the potential for dynamic densification of these materials can be mitigated by removal of the materials and then replacing them as compacted fill. Potential for seismic settlement (dynamic densification) is negligible in the bedrock portions of the site.
Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 9
The hillside areas directly adjacent to the road alignment are designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potential for earthquake-induced landslides is required (see Figure 4).
The potential for earthquake-induced slope failures and surficial failures on the critical natural and proposed design slopes will need to be evaluated at the design stage and, if necessary, provide mitigation measures. Cut and fill slopes constructed per the California Building Code typically are not subject to earthquake-induced failures.
Typical mitigation for slopes prone to earthquake-induced failures include avoidance, removal of surficially unstable materials, laying back the slope to a shallower gradient, buttressing, construction of shear keyways, or debris basins and walls that may be designed to divert and/or collect the calculated volume of material expected to fail.
Additionally, no landslides have been mapped at the project site. Due to the relatively shallow dip of the bedding of the Pacoima Formation and the Saugus Formation bedrock, and of the flat-lying alluvial deposits that underlie the site, the potential for differential materials response and slippage along weak bedding planes is considered to be negligible.
5.2 Slope Stability
Proposed slopes, future grades, and existing grades are not shown on the current project plans. It is anticipated that both cut and fill slopes will be necessary at various locations along the proposed alignments and that cut slopes will expose Saugus Formation and Pacoima Formation bedrock. These proposed slopes should be designed and constructed at gradients of 2:1 horizontal to vertical or shallower. All constructed slopes should be evaluated by a geotechnical firm for conformance to applicable requirements/standards for gross and surficial slope stability. If it is determined that proposed slopes do not satisfy required factor of safety requirements for gross slope stability, mitigation measures will have to be designed based on results of slope stability analyses. If surficial stability of the proposed slopes is determined to be insufficient, measures to mitigate surficial stability will be required. This may include but not be limited to the following:
1. Avoidance.
2. Stability fills.
3. Flattening of slopes to 3:1 (h:v), or flatter.
4. Seeding/planting of slopes.
5. Guniting of slopes.
6. Mechanically Stabilized Earth (MSE) slopes.
Natural slopes adjacent to the proposed road alignments exposing adverse geologic Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 10
bedding conditions or steep gradients should be evaluated. If it is determined that these slopes do not satisfy required factor of safety requirements the natural slopes may be stabilized with Buttress Fills or Shear Keys designed by the Project Geotechnical Engineer.
Laboratory testing of fill source materials is required to evaluate both gross and surficial stability of the proposed fill slopes, including remedial Buttress Fills and Stability Fills.
Shear strength testing should be performed on soil samples that represent the mixture of materials that will be placed in the proposed fills.
Steep natural slopes adjacent to the proposed road alignment should also be evaluated for potential debris flow hazards. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards.
5.3 Deep Fills
Based on preliminary review of the proposed road alignments, deep fill areas (i.e. fills deeper than 40 ft below proposed grade) are not anticipated.
5.4 Soil Compressibility
Rapidly buried, unsaturated sediments, such as colluvium and alluvium, commonly contain extensive voids and, as a consequence, are subject to hydro-compression (collapse) settlement when inundated. Hydro-compression occurs when water enters sediments and reorients the sediment particles into a more compact arrangement with fewer and smaller voids. Compacted fills and structures constructed over deposits prone to hydrocompression may experience settlement and associated distress and damage.
Based on explorations for the adjacent Old Town Newhall Library site, alluvial soils at the project site are anticipated to be typically medium dense to depths of 30 to 40 ft, with local loose zones in the upper 10 ft. The density of the artificial fill placed below the railroad tracks is currently undefined. The potential for settlement within these units should be addressed in more detail during a future geotechnical investigation at the design stage.
If soils subject to hydro-compression or consolidation are identified at the site, settlement and potential adverse impacts to the proposed road improvements can be mitigated by removal and recompaction of loose or soft material.
The phenomenon of hydro-compression does not apply to the bedrock deposits that underlie most of the site. Further exploration should be performed at the site to evaluate if hydro-compression-prone materials, such as colluvium, are present in areas where pavements or compacted fills are proposed.
Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 11
5.5 Erosion Potential and Drainage
Fill, bedrock, and soil materials at the site will be susceptible to erosion if drainage features to control sheet flow over the ground surface are not provided. The drainage features should be designed to prevent water from ponding on graded areas and from flowing over natural or constructed slopes, and should direct surface water to designed debris basins or natural drainage courses, where applicable. Debris material generated by erosion of site materials should be contained inside the site boundaries.
The potential for erosion of the banks of Newhall Creek should be evaluated by the project civil engineer.
5.6 Dam Inundation and Flooding
No dams currently exist in the Newhall Creek Drainage and the site is not in a dam inundation area per the Flood and Inundation Hazard Map (Plate 6) of the Los Angeles County Safety Element of the General Plan. The potential for dam inundation is therefore considered nonexistent. The potential for flooding of Newhall Creek should be evaluated by the project Civil Engineer.
5.7 Construction Considerations
5.7.1 Rippability
The site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill. These materials can be ripped with standard grading equipment.
5.7.2 Oversized Material
The alluvial and bedrock materials underlying the site may contain significant quantities of oversized material. Additionally, the dumped fill located along the southwest bank of Newhall Creek contains common blocks of asphalt and concrete as well as scattered boulders, car parts, and other oversized debris. Any oversized material that may be encountered during construction should not be incorporated into potential compacted fill during grading operations. Specifications and guidelines for handling and disposal should be addressed by the project geotechnical engineer at the design stage.
5.7.3 Expansion Potential of Soils
The site alluvial materials are generally granular and are not typically expansive in nature. However, fine-grained units of the Saugus Formation are known to have significant expansion potential when exposed to water. In addition, Pacoima formation bedrock, artificial fill, colluvium and alluvial deposits present at the site may contain Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 12
material with significant expansion potential. Expansive materials at the site should be evaluated by the Project Geotechnical Engineer during the grading plan stage of development. Expansion potential of site soils can be mitigated by controlling the water content and density of fill soils, by specifying embedment and reinforcement of structures, and by removing the expansive materials and replacing them with compacted material with low expansion potential.
5.7.4 Soil Corrosivity
Past experience with similar soils on nearby sites suggests that the on-site soils likely have a low concentration of sulfate and chloride, and low acidity. This indicates a low potential for corrosion of concrete and, therefore, it is anticipated that Type I or II Portland cement will be satisfactory for use at the site. The resistivity of similar soils near the site tested by this firm indicates that they are typically moderately corrosive to ferrous metals. The corrosive characteristics of the site soils should be verified with laboratory testing at the design stage. If corrosive soils are encountered, options to mitigate potential corrosive soils include protective wraps and coatings for buried metal pipes and special types of cement that are resistant to corrosion.
5.7.5 Shrinkage and Bulking of Materials
Typically, soil, colluvium, uncompacted artificial fill, alluvial deposits, and terrace deposits (i.e. Pacoima formation bedrock) reduce in volume (“shrink”) by up to about 10 percent when excavated and subsequently recompacted. In contrast, Saugus Formation bedrock typically increases in volume (“bulk”) by up to about 5 percent when excavated and recompacted. In order to evaluate the cut-fill balance of the proposed grading, shrinkage/bulking of on-site materials including landslide debris should be estimated at the design stage.
5.8 Retaining Walls
The grades at the northeast end of Lyons Avenue and adjacent portions of Railroad Avenue will need to be raised in order to tie into the existing grade at the railroad crossing.
It is our understanding that retaining walls may be used to accommodate the changes from the proposed grades to adjacent properties proposed to remain at existing grades.
Geotechnical parameters for these walls and for design of the proposed box culvert and associated wing walls for the Newhall Creek crossing should be addressed at the design stage.
5.9 Oil Wells and Water Wells
Review of the Munger Map Book and California Division of Oil and Gas records indicates Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 13
that no oil wells have been drilled on or immediately adjacent to the site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated.
Review of LACFCD records indicates that water wells have been drilled in the vicinity of the proposed road alignments (see Water Well Location Map, Figure 2). If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated.
6.0 PROJECT FEASIBILITY
The proposed development is feasible from a geologic and geotechnical standpoint and will be safe from geologic hazards provided that the geologic and geotechnical recommendations outlined in this report, along with appropriate building and grading codes, are taken into account during the planning, design and construction phases of the project.
7.0 CONCLUSIONS AND RECOMMENDATIONS
The following conclusions and recommendations summarize the primary geologic and geotechnical issues that may impact the proposed development:
1. Potential for primary ground rupture on a fault at the site is considered to be low.
2. Peak ground acceleration (PGA) consistent with maximum considered earthquake (MCE) ground motions is expected to be 1.03g in alluvial portions of the site (and 1.10g in portions of the site where bedrock outcrops or is present at shallow depth.
3. The alluvium that underlies portions of the site is not designated as potentially liquefiable on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle. In addition, historic high ground water elevations are greater than 50 ft in depth. Therefore the potential for liquefaction of alluvium is considered very low.
4. The potential for seismic settlement (dynamic densification) during future seismic events is non-existent in the bedrock portions for the site but should be evaluated in site alluvial soils, colluvium, and existing artificial fills to remain in place.
5. All slopes should be evaluated by the Project Geotechnical Engineer at the planning and design stages. The hillside area of the site is designated on the State of California Seismic Hazard Zone Map to have earthquake-induced slope instability. However, the potential for earthquake-induced slope failures is considered low provided that future Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 14
geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction.
6. No landslides have been mapped on the subject site.
7. Stability of cut slopes that are constructed at gradients of 2:1 or shallower are anticipated to expose favorable bedding conditions and be grossly stable. However, cut slopes will require subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses.
8. A study should be conducted at the design stage to confirm the geologic conditions of natural slopes. This study should include subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending slopes are not stable as determined by geologic or geotechnical stability analyses.
9. A study should be conducted at the design stage to evaluate potential debris flow hazards on steep natural slopes ascending from the proposed road alignments. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards.
10. Rapidly buried silty sediments such as thick colluvium and alluvium may be subject to hydro-compression. A study should be conducted to evaluate the hydro-compression potential of colluvial deposits and portions of the alluvium. Materials characterized as susceptible to hydro-compression tests in the laboratory can be mitigated by removal prior to the placement of fill. Specific recommendations should be provided at the design stage.
11. The bedrock is moderately consolidated, which indicates that grading operations can be performed with conventional equipment.
12. Cobbles and small boulders are likely present within the alluvium and bedrock. This oversize material may present difficulties during cutting operations with some types of equipment. In addition, oversize material will require special handling during fill construction.
13. A study should be conducted to evaluate the expansive potential of fine-grained soils during the design stage. If potentially expansive units are encountered in the street grades during construction, they should be evaluated by Expansion Index (EI) tests by Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393
October 17, 2014 Page 15
the Project Geotechnical Engineer relative to mitigations. The expansive material can be removed to a specified depth determined by the Project Geotechnical Engineer and replaced with soil with very low to non-expansive characteristics. Alternatively, the expansive soil may be treated with additives to lower the expansion potential.
14. Soils on site may be corrosive to concrete and ferrous metals. Soil moisture, chemistry, and other physical characteristics all have important effects on corrosivity. Testing during development will indicate what special measures, such as cement type in concrete and corrosion protection for metallic pipes, may be required for construction.
15. Planting and irrigation of cut slopes and fill slopes should be included in future design phases in order to improve surficial stability of slopes and to mitigate potential for erosion.
8.0 LIMITATIONS
This report has been prepared by Allan E. Seward Engineering Geology, Inc. for the exclusive use of the City of Santa Clarita and its design consultants for the specific site discussed herein. This report should not be considered transferable. Prior to use by others, this firm must be notified, as additional work may be required to update this report.
In the event that any modification in the location or design of the proposed development is planned, the conclusions and recommendations contained in this report will require a written review by this firm with respect to the planned modifications.
The proposed development is located in southern California, a geologically and tectonically active region, where large magnitude, potentially destructive earthquakes are common.
Therefore, ground motions from moderate or large magnitude earthquakes could affect the project site during the design life of the project. The current standards for construction provided in the California Building Code are designed to safeguard against major failures and loss of life, but are not intended to prevent damage, maintain function or provide for easy repair. Conformance to code standards does not constitute any kind of guarantee or assurance that significant structural damage will not occur in the event of a maximum level of earthquake ground motion. However, it is reasonable to expect that a well-planned and constructed structure will not collapse in a major earthquake and that protection of life will be reasonably provided, but not with complete assurance.
Typically, faulting is confined to the area adjacent to a known fault. However, absolute assurance against future fault displacement in other areas is not possible in tectonically active regions because new faults can form over time and long inactive (pre-Holocene) faults may be reactivated in response to evolving tectonic stresses and geologic conditions in the earth’s Allan E.

crust. Therefore, the timing, location and magnitude of new ground surface ruptures during a seismic event cannot be known with certainty.
In performing these professional services, this firm has used the degree of care and skill ordinarily exercised under similar circumstances by reputable geologists and geotechnical engineers practicing in this or similar localities. It should be recognized that subsurface conditions can vary in time, and laterally, and with depth at a given site. Therefore, our conclusions and recommendations are professional opinions and are not meant to be a control of nature. We make no other warranty either expressed or implied.

Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Rivertech is pleased to submit this report that documents the analysis of the hydraulics, sedimentation, scour potential and bend shear stress for the proposed Dockweiler Road crossing of Newhall Creek located in the City of Santa Clarita, Los Angeles County, California. It is our hope that the contents of this application are sufficient for an expedient review and approval process.
This drainage concept study evaluates the hydraulic and scour impacts of the proposed box culvert in Newhall Creek and documents on-site and off-site hydrology and drainage patterns.
This report summarizes findings and proposed channel improvements and modifications including recommended scour countermeasures.
Rivertech performed a scour analysis at the future Dockweiler Road Bridge to determine the scour potential per the methodology accepted by the County of Los Angeles. Provided in this study are the hydraulic conceptual design to evaluate the need for potential countermeasures for scour protection. The Location of the site is shown on Figure 1.
Figure 1. Site Location Map.
INTRODUCTION/PURPOSE OF STUDY
The purpose of this study is to evaluate the future extension of Dockweiler Road and conceptually the planned Dockweiler Road Bridge, which will connect to Lyons Avenue, over Newhall Creek. This hydraulic and scour study associated with the proposed Dockweiler Road and Lyons Avenue extension is focusing on following tasks:
Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California To determine the scour and channel stability characteristics, perform hydraulic analysis applying the Capital Flood and Flood Insurance Study (FIS) flows of the Newhall Creek Channel between Master College and existing 15th Street bridge. To determinate the existing and post-project scour potential with implementation the proposed bridge over Newhall Creek Channel
To recommend Newhall Channel countermeasure that will provide more channel stability and mitigate the scour potential.
LITERATURE REVIEW
Rivertech reviewed and implemented all the relevant information and data, specifically but not limited to the site plans, design plans and prior reports and studies.
TECHNICAL APPROACH
The basis for this hydraulic and scour study is the existing technical data and field reconnaissance. Existing technical data such as record plans, available hydrology data and flood studies, floodplain maps and topographic data were reviewed for relevance and applicability for this study of the proposed site. Data sources included the LACFCD, FEMA and the US Army Corps of Engineers.
Hydrology Data
The hydraulic, sedimentation and scour analyses require both steady-state and unsteady flow. For the one-dimensional hydraulic and scour analyses, peak flows are needed as input data.
Peak Flow
One of the sources of hydrologic data is the Los Angeles County Flood Control District (LACFCD) Design Division who provided hydrologic data for Newhall Creek Channel, which was part of 2001 to 2005 LACFCD comprehensive study for the South Fork of the Santa Clara River watershed. Peak flows for Newhall Creek sub-areas are provided for 50-year clear-flow, 50-year burned-flow and 50-year burned/bulked (Capital Flood).
The second source of hydrologic data is the Federal Emergency Management Agency, as part of the Flood Insurance Study, which provides 100-year peak flows.

Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Reviewing the drainage information associated with Newhall Creek Channel as provided in these studies, the LACFCD public works policy of flood protection, and the drainage policy for Santa Clara River per Section 2.2 of the LACFCD Sedimentation Manual it can be concluded that the Newhall creek channel shall be designed based on the Capital flood rates (50-year rainfall, burned and bulked) and channel section of soft bottom with protective levee. These design requirements are consistent with the existing flood control improvements per LACFCD as-built plans "Newhall Creek unit 1A" and Storm Drain Plans in Tract No.32365.
Unsteady Flow
The sediment transport modeling requires time-varied flow as the upstream boundary condition.
The hydrologic data, which was furnished by the aforementioned sources, is for steady-state conditions.
Although there are no streamflow gages along Newhall Creek and one abandoned short-term gage along the South Fork of the Santa Clara River, there are a few gages in the Santa Clara River watershed that exhibit similar hydrologic characteristics to Newhall Creek. The USGS streamflow gages that are meet the minimum record length (10 years) criterion and are located in the same hydrologically region, are: Santa Clara River Near Saugus, CA (11108000), Santa Clara River Ab Rr Station Near Lang, CA (107745) and Bouquet Canyon Near Saugus, CA (11107860). The annual peak flows were determined from each of the gage records and used as input to a Log Pearson Type III streamflow gage analysis.4 The peak flows from this flood
frequency analysis was plotted as a function of the drainage area of the respective gage, as shown in Figure 2. From these points, least-squares best-fit lines were fit to the data and the equation of each line is shown in Figure 2.
The drainage area of Newhall Creek at the proposed is 7.7 mi2 , which would extrapolate all of
the flows of the frequencies in Figure 2 well below 100 ft3 /s. Therefore, using these curves to
establish historical flows by relating to other gage sites is not feasible. Alternatively, the records for all three gages were reviewed for flow magnitudes that are comparable to the peak flows estimated in Table 1. From these records, “wet’ and “average” water years, corresponding to 2003 and 1962, respectively, were selected. There are several dry years but these do not yield significant aggradation and degradation.

The digital terrain model of existing conditions was based on the 2 feet interval aerial topography provided from the City of Santa Clarita.
Hydraulic Modeling
Rivertech will develop an existing and post-project HEC-RAS5 hydraulic model of the Newhall Creek Channel at the proposed Dockweiler Road bridge crossing to determine the hydraulics parameters to be used in the scour analysis.
The river tools of the Watershed Modeling System (WMS)6 software was used to develop a terrain model from the CAD drawings, from which a flow line was delineated and cross sections were cut. This georeferenced data was exported to HEC–RAS, which served as the existing hydraulic model geometric base. Modifications were made to reflect the existing bridges, roughness and other input parameters.
One bridge/culvert structure was included in HEC-RAS model. The Newhall Creek Channel Bridge consists of four box culverts with 24' span and 8’ rise at the crossing with Lyons Avenue extension. Using the HEC-RAS tool, the proposed Newhall Creek Channel floodplain limits

Study Boundary Conditions
The Newhall Creek study reach boundaries are Placerita Creek and the survey limits (approximately 3,000 feet downstream of the SR14 crossing) at the downstream and upstream limits, respectively. Based on the available topographic survey, the average channel slope of
0.4% was applied to determine the downstream normal depth, which is added to the channel invert to arrive at the starting water-surface elevation.
HYDRAULIC ANALYSIS AND RESULTS
The proposed bridge, an extension of Dockweiler Road and Lyons Avenue over Newhall Creek Channel crossing was modeled using the culvert hydraulics computer program HY-8.7 The
proposed four 24-feet wide and 8-feet deep opening reinforced concrete bridge will accommodate the Capital Flood.

Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Figure 4. Hydraulic Sections, Plan View
Based on the LACFCD Sedimentation Manual recommendation for the Santa Clara River watershed, it is proscribed that the Newhall Creek be improved as a soft bottom channel with protected levees. To convey the Capital Flood, a discharge of 9,200 ft3/, the proposed channel section will require a trapezoidal section with an 80-foot wide base and 2:1 lined side slopes.
This section is similar to the existing upstream improvements at Del Oro Street crossing with Newhall Creek.
HEC-RAS model input and output data, including cross sections and detailed tables are provided in the Appendix for reference. The floodplain map for Capital peak flow is provided in the Appendix.
Existing Condition
The cut sections using the WMS river tools were imported into HECRAS as georeferenced geometry. This geometric data was then modified and amended to accurately reflect the hydraulic characteristics, e.g., bridges, channel banks, roughness, etc. The model includes the Railroad Avenue and Southern Pacific Railway bridges. Boundary conditions, i.e., flows and starting water-surface elevations, were added to complete the model.
Figure 5 illustrates the resulting water-surface profiles for the existing condition.
The detailed input and output of the existing condition hydraulic model is exhibited in the appendix.

Post‐Project Condition
The implementation of the proposed bridge and channel widening are two significant components of the post-project hydraulic model. The bridge has four 25-foot wide and 8-foot deep openings. The approach to the bridge is an improved channel that is trapezoidal in shape with na 80-foot bottom width and 2:1 aide slopes.
The hydraulic sections and input from the existing condition model was the basis for the postproject with the implementation of the proposed bridge and channel widening.
The results of the HEC-RAS hydraulic model output indicate that the proposed bridge and channel improvement will accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year burn/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Figure 6 illustrates the resulting water-surface profiles for the post-project scenario.
The detailed input and output of the post-project scenario hydraulic model is exhibited in the appendix.

SCOUR ANALYSIS
The results of the post-project hydraulic model were used to determine the long-term aggradation/degradation process. We will determine total maximum scour, which would include bank and bed erosion, bend (if measurable) and contraction/expansion influences.
Scour Analysis
The first part of the study is to determine the potential scour due to the implementation of the project. The three scour processes that occur are long-term, contraction and bend scour – the latter due to the natural bend in the exit segment of the study reach. The results of the HEC-RAS model were used to define the hydraulic characteristics required as input for the scour and shear stress analyses.

Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Muller (1948) and Einstein (1950).8
The Meyer-Peter and Muller equation is recommended for
bed material coarser than 5 mm, which does not apply for this stream system in this model, so it was not used. Ackers and White or Engelund and Hansen's equation is recommended for subcritical flow in the lower flow regime. However, there is a mixed flow where some reaches are subcritical and supercritical flow, so this system may not be the most appropriate application of these methods. The Laursen equation is best suited for laboratory flumes and shallow rivers with fine sand or coarse silt. The Yang equation is recommended for sand transport in laboratory flumes and natural rivers, which is an appropriate application for this stream system.
Fall velocity is computed using the Toffaletti equation, the recommended method for sand-bed rivers, which is the case for this application. The default extent of erodible lining is set to the cross section bank limits. The maximum depth of erodibility is a user-defined input and limits the lower limit to which degradation is set.
Boundary Conditions: Sediment Load
The input options in the HEC-RAS sediment transport module for sediment load are equilibrium load, rating table and user-defined sediment load series. Lacking any historical sediment load data, the equilibrium load was applied.
Sensitivity analysis, Sediment Transport
The various applicable transport functions, including Yang, Ackers and White, Engelund and Hansen, Copeland and Laursen were considered and evaluated for this model. The results of these bed-material load models yielded similar results but the Yang method was most consistent and stable, so it is the recommended method. The modeling results in this study reflect the Yang method.
Using the nationwide guidelines for long-term aggradation/degradation, and the HEC-RAS hydraulic model implementation of HEC-6, we developed a sediment transport model, using the Yang (sand) methodology. This type of scour is not a result of a specific single event but rather a series of events over time. Observed (gage) data is not available in Newhall Creek or the South Fork of the Santa Clara River so an approximation of the flood flow is made to estimate the potential long-term scour. The sediment transport model simulated a series of time-varied flows with varying durations for a poorly graded sandy channel to determine the maximum scour depth for peak flows of 4,620 and 7,290 ft3
/s, corresponding to water years 1962 and 2003.
Soil samples were taken along the bed and bank and used in the laboratory sieve analyses, which yielded particle size distribution curves, shown in Figure 7, that were input in the sediment transport models. As can be seen in Figure 7, the median grain size for the two samples are 1.0 and 2.0 mm, respectively.

Figure 8 illustrates the maximum aggradation and degradation event, which corresponds to water year 1962. The system is in balance with the upper reaches deposit zones and the lower reaches erosion zones. As can be seen, the proposed bridge causes aggradation in the approach sections and a minor scour depth in the exit sections adjacent to the bridge. Hence, the computed maximum scour depth, set to 0.3 feet, corresponds to a simulation time of one year. The results of this analysis are presented in the appendix.

Contraction Scour
Using the nationwide guidelines for contraction scour9
and the HEC-RAS hydraulic model
developed for the site, we estimated the potential scour due to contraction caused by the transition in the exit section back to the existing channel. Since the channel is in live bed condition, the live-bed contraction scour equation governs:

For this analysis, the relevant grain sizes were obtained from a sieve analysis of a soil sample in the scour zone.10 The input and output for this analysis are exhibited in the appendix. The HECRAS results yield a contraction scour depth of 0.0 feet for the proposed bridge.
The pier scour, using the CSU equation, is negligible but the abutment scour is estimated to be
22.2 feet and 27.3 feet, for the Capital Flood and FIS 100-year, respectively. The total maximum potential scour is the sum of the long-term, contraction, pier and abutment scour which is conservative estimate of 27.6 feet.

Where: Dmxb is the maximum water depth in the bend; Dmnc is the average water depth in the crossing upstream of the bend; W is the width of the bend; and Rc is the centerline radius of the bend.
For this stream bend, we determined that Rc, W and length of curvature, Lc, are 265, 137 and 500 feet, respectively. The computations for this analysis are exhibited in the appendix. The results for the Capital Flood and FIS 100-year yield bend scour depths of 2.4 and 2.3 feet, respectively.
Streambank Mechanics
There is a bend that is located approximately 500 downstream of the proposed bridge and is therefore within the hydraulic zone of influence. Associated with this bend is a concentration of shear stress directed to the right (east) bank of the Newhall Creek channel.
Erodibility Index Method
Erosion potential within the channel can be assessed using the Erodibility Index Method (EIM)12 and Shields Parameter. These approaches have been used in this study to assess the stability of the study reach. EIM determines that power of the stream flow and compares it to the power to resist by the channel lining, which in this case is sand.

New York. McGraw-Hill. (pp. 122-259), 2006 Hydraulic and Scour Study,
Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California As can be seen in Figure 7, the stream power varies along the study reach. Within the segment of proposed improvements, the maximum power is 605 W/m2, which corresponds to a minimum bulb size of 250 mm, if vegetation was implemented as the natural mitigation for channel stabilization. Details of this analysis is exhibited in the appendix.

Radial Stress
We estimated the shear stress at the bend using Begin’s approach, as documented in HEC-23:

Where: Ab is area of the outer bend; φr is radial stress; F is centripetal force; ρ is fluid density; Q is discharge; V is velocity; and Y is mean flow depth.
The computations for this analysis are exhibited in the appendix. The results of the Capital Flood and FIS 100-year yield bend shear stresses of 60.4 and 47.2 lb/ft2 , respectively. From the HEC-

Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California RAS hydraulic model, the average shear stresses on the bed in the bend reach are 1.3 and 0.9 lb/ft2. Therefore, the total shear stress is the sum of the average shear stress on the bed and radial shear stress which is 61.7 and 48.1 lb/ft2, respectively. These estimates are extremely conservative, so verification with another methodology would be advisable.
Chang’s Stream Power
As an alternative approach, we applied the more robust Chang Transverse Stream Power methodology with the aid of the Mathcad14computer program. This application is too complex to summarize in the body of this letter so the input and output for this analysis are exhibited in the appendix. The results yield a total calculated shear stress, τc, on the outer streambank of 7.7 lb/ft2, which is the design shear stress that is recommended. So any lining of the channel along the bend would have to greater than or equal to 7.7 lb/ft2 to be stable.
SCOUR COUNTERMEASURES
In addition to the vegetative treatment proscribed in the prior section, there are high shear zones in the exit section of the proposed bridge where more robust countermeasures may be required.
Based on the results of the hydraulic and scour analyses, we are prescribing lining and energy dissipators to resist the computed erosive forces and recommend mitigation measures. With the aid of HY8 and the methodology of HEC-1415, countermeasures to mitigate the highly-erosive exit velocities of the proposed bridge were evaluated. The feasible alternatives, whose criteria were met by the proposed bridge and hydraulic characteristics, are limited to the following streambed level structures: riprap basin, CSU Basin and Contra Cost Basin, the latter two being rigid structures. The riprap basin, illustrated in typical plan and sections in Figure 10, is recommended but comes with a relatively large footprint, with a total length of 400 feet and width of 366 feet, both of which will need to be reduced to fit the channel physical constraints.

RECOMMENDATIONS AND CONCLUSION
In summary, the existing Newhall Creek Channel does not have the capacity to convey the FIS 100-year and the Capital Flood flow rates. As a result, the 100-year model results show that a significant percentage of the flow spill out the main channel and flood the railroad, entering the Railroad Avenue.
As part of the proposed Dockweiler Road / Lyons Avenue extension, there are four 25-foot wide and 8-foot deep openings in a concrete box bridge at the crossing of the Newhall Creek channel and the channel improvement to trapezoidal sections with 80-foot wide soft base and 2:1 protected side slopes. The proposed improvements accommodate Capital Flood, with no overtopping, and will not create any flood hazard for the adjacent railroad and proposed street improvements.
The results of this study provide the calculated shear stress on the streambank. In order to protect the streambank from erosion, a lining with a permissible shear stress, τp, greater than τc must be installed. Riprap and vegetation linings are recommended for the high and moderate shear zones, respectively.
The two methodologies that we applied yield similar results, albeit, the HEC-23 radial stress approach is more conservative. In the respective documentations for the two approaches, it is stated that the HEC-23 has limited field verification, whereas, the Chang method has been more thoroughly verified with field data. Therefore, despite the conservatism of the HEC-23 approach, we recommend implementing a countermeasure that has a permissible shear stress, τp greater than the calculated shear stress, τc as determined using the Chang Stream Power methodology.
Sensitivity analysis, Sediment Transport
The various applicable transport functions, including Yang, Ackers and White, Engelund and Hansen, Copeland and Laursen were considered and evaluated for this model. The results of these bed-material load models yielded similar results but the Yang method was most consistent and stable, so it is the recommended method. The modeling results in this study reflect the Yang method.
