June 1, 2006 The Honorable Board of Supervisors County of Los Angeles 383 Kenneth Hahn Hall of Administration 500 West Temple Street Los Angeles, CA 90012 Dear Supervisors: PRIVATE DRAIN NO. T 728 GRANT OF EASEMENT CITY OF WESTLAKE VILLAGE SUPERVISORIAL DISTRICT 3 3 VOTES IT IS RECOMMENDED THAT YOUR BOARD ACTING AS THE GOVERNING BODY OF THE LOS ANGELES COUNTY FLOOD CONTROL DISTRICT:

1. Acting as a responsible agency pursuant to the California Environmental Quality Act (CEQA), consider the enclosed Negative Declaration/Finding of No Significant Impact, including comments received during the public review process, which was prepared by the California Department of Transportation (Caltrans). This report was approved by Caltrans and the Federal Highway Administration for the Lindero Canyon Road and U.S. 101 Street and Ramp Improvement project on August 23 and September 13, 2001, respectively; find that the granting of the recommended easement is within the scope of the proposed project; find that the proposed project will not have a significant effect on the environment; find that the Negative Declaration/Finding of No Significant Impact document reflects the independent judgment of the County; and approve the Negative Declaration/Finding of No Significant Impact document.

The Honorable Board of Supervisors June 1, 2006 Page 2

2. Acting as a responsible agency pursuant to CEQA, consider and adopt the Mitigation Monitoring Program (included in the Negative Declaration), which was prepared and adopted by Caltrans as a condition of the project to mitigate or avoid significant effects on the environment.

3. Find that the proposed grant of an easement for public road and highway

purposes in, over, and across Private Drain No. T 728 from the Los Angeles County Flood Control District to the City of Westlake Village and the City's subsequent use of said easement will not interfere with the use of Private Drain No. T 728 for any District purpose.

4. Approve the grant of an easement for public road and highway purposes

from the District to the City of Westlake Village within Private Drain No. T 728 (2,455± square feet) for $13,500. The subject parcel is located at the northeast corner of the intersection of Lindero Canyon and Agoura Roads in the City of Westlake Village.

5. Instruct the Chair to sign the enclosed Road Deed and authorize delivery

to the Grantee.

PURPOSE/JUSTIFICATION OF RECOMMENDED ACTION This action will allow the District to grant an easement within Private Drain No. T 728 to the City of Westlake Village. The City requested the easement for the road widening of Lindero Canyon and Agoura Roads in connection with Caltrans' Lindero Canyon Road and U.S. Highway 101 Street and Ramp Improvement project. The granting of this easement is not considered adverse to the District's purposes. Implementation of Strategic Plan Goals This action meets the County Strategic Plan Goal of Fiscal Responsibility. The revenue from this transaction will be used for flood control purposes. FISCAL IMPACT/FINANCING The $13,500 proposed selling price represents the market value of the easement. This amount has been paid and deposited into the Flood Control District Fund.

The Honorable Board of Supervisors June 1, 2006 Page 3 FACTS AND PROVISIONS/LEGAL REQUIREMENTS The granting of this easement will not hinder the use of the channel for possible transportation, utility, or recreational corridors. The enclosed Road Deed has been approved by County Counsel and will be recorded. ENVIRONMENTAL DOCUMENTATION On May 3, 2001, Caltrans, as the lead agency, circulated a Negative Declaration/Finding of No Significant Impact for the Lindero Canyon Road and U.S. 101 Street and Ramp Improvement project in accordance with CEQA requirements. The mitigation measures included in the CEQA document for the project specifically address air quality, archeologic-historic, flood plain/flooding, geologic/seismic, noise, public services, soil erosion/compaction/grading, traffic/circulation, vegetation, and water quality issues. The Negative Declaration/Finding of No Significant Impact concluded that the project, with the proposed mitigation measures, will not have a significant effect on the environment. The public comment period did not raise significant environmental issues with the project; therefore, Caltrans finalized and adopted the Negative Declaration/Finding of No Significant Impact on August 23, 2001. Under CEQA, the District is a responsible agency whose discretionary approval of the project is required in order to carry out the project. As a responsible agency, your Board must consider and adopt the Negative Declaration/Finding of No Significant Impact and the Mitigation Monitoring Plan prepared by Caltrans before the recommended easement is granted. IMPACT ON CURRENT SERVICES (OR PROJECTS) None. CONCLUSION Enclosed are an original and duplicate of the Road Deed. Please have the original and duplicate signed by the Chair and acknowledged by the Executive Officer of the Board. Please return the executed original to Public Works and retain the duplicate for your files.

Description

,;

The project consists of widening Lindero Canyon Road from Agoura Road to Via Colinas in theCity of Westlake Vilage including median reconstruction and re-striping of Undero CanyonRoad, construction of a bike path and widening the southbound Lindero Canyon Road on-rampto northbound US 101 (Ramp G-6) within the Caltrans right-of-way. The reconstruction andwidening of portions of Lindero Canyon Road and Ramp G-6 was generated by the projectedYear 2020 traffc conditions. Land uses in the immediate vicinity of the project site consist ofOffce Commercial, Specific Plan (Commercial) and Commercial Recreation.

Summary of Review Process'

A Public Notice was published on May 3, 2001 in the Los Angeles Times inviting publiccomments on the Draft Initial Study/Environmental Assessment which was prepared for theproposed project. The public review penod closed on June 18, 2001. The Draft InitialStudylEnvironmental Assessment was also circulated to the State Clearinghouse on May 3,2001 for distrbution to affected agencies for their review and comment.

Summary of Comments Received on Draft Initial Studv/Environmental Assessment

-)

No comments were received on the Draft Initial Study/Environmental Assessment from thepublic. No comments were received from agencies receiving copies of the Draft Initial'StudylEnvironmental Assessment through the State Cleannghouse, with the exception of theCalifornia Department of Fish and "Game (CDFG). The CDFG expressed concerns regardingproject-related water quality impact to streams and watercourses in the project vicinity. TheCDFG also recommended that a pre-construction survey be conducted for bats, swallows, andnesting birds in the project area and that a buffer be maintained. between nesting areas andconstruction activities. Both concerns expressed by the CDFG have been addressed by new orrevised project mitigation measures.

Summary of Mitiqation Measures

1. If .groundwater is encountered during construction and dewatering is necessary, the effuent

generated shall be containerized and disposed of off-site or be treated and discharged on-site after regulatory approval of appropnate permits.

2. If excavation of the sewer line is conducted and soil affected by chlorinated vac is

encountered, the affected soil shall be containerized arid disposed of off-site or be treatedand discharged on-site after regulatory approval of appropriate permits.

-J. Soils alor.g on-ramp G-6 shall be tested for aerially deposited lead in accordance with latestpolicies during the design stage of Phases 1 and 2. If such soils are found, they shall beproperly disposed of in accordance with the special management requirements of a varianceissued to CAL TRANS by the DSTC.

. :~j

4. To reduce noise levels below the established noise standards of the City of WestlakeVillage, the project shall comply with the special provisions of the City's noise ordinanceaddressing construction noise, including provisions Jorlimiting hours of construction in orderto reduce adverse effects on sensitive receptors.

5. Native plant species shall be used to revegetate embankments and roadway edges.Planting and hydroseeding shall be utilized for erosion control purposes.

6. If project activities are to occur during the nesting season of birds (March 1 to September 1),a pre-construction survey for breeding bats and swallows and other nesting birds shall beconducted per California Department of Fish and Game guidelines. A buffer of at least 150feet for construction activities shall be maintained for any active bird bests (500 feet forraptor nests). .

¡

\J

7. The applicant shall consult with local police, fjre and other emergency service providers todevelop temporary alternatives to the use of Lindero Canyon Road as an emergencyresponse or evacuation route during project construction.

8. If buried historic or prehistoric resources are found during the excavation activities,excavation activities shall be halted and an archaeological monitor shall be retained toformally evaluate such resources for their significance and/or importance pursuant to CEQA.

Determination

An Initial Study/Environmental Assessment has been prepared by the California Department ofTransportation (Caltrans). On the basis of this study it is determined that the proposed actionwill not have a significant effect upo'n the environment for the following reasons:

1. There wil be no effect on: unique or natural features, plant or animal life, habitats,archaeological, historic, agricultural, scenic or timber resources, residences, businesses,schools or neighborhoods, flood plains, wetlands or water bodies.

City of Westlake Vilage Lindero Canyon Road at US 101

INITIAL STUDY/ENVIRONMENTAL ASSESSMENT

A. PURPOSE OF AND NEED FOR PROJECT

The City of Westlake Vilage (City) proposes to widen Lindero Canyon Road and Ramp G-6 at U.S. Highway 101 (US 101) K.P.59.55/61.15. The proposal to reconstruct and widenportions of Lindero Canyon Road and ramp G-6 was generated by the projected Year 2020traffc deficiencies as summarized in the combined Project Study ReportProject Report,Section 6, Traffc and Accident Data and WPA Traffc Engineering, Inc, US 101- LinderoCanyon Road PSR Traffc Analysis, April, 1997.

.-i

The project is needed in order to accommodate future anticipated growth and to reducecongestion and related accidents. As can be seen in Table 1, below, four (4) keyintersections wil have deficient operations by the year 2020 without the proposedimprovements. The proposed improvements wil assist the City in achieving objectivesincluded in the City's General Plan Circulation Element. The Circulation Element

establishes LOS C as the minimum acceptable level of service at all intersections withinthe City, except that LOS D is acceptable at intersections along Lindero Canyon Roadbetween Agoura Road and Via Colinas. These minimum acceptable levels of service wilbe achieved (with the exception of the intersection of Lindero Canyon Road and ViaColinas) with implementation of the project.

Lindero Canyon Road is a major arterial highway in the City of Westlake Vilage. It iscurrently striped for two lanes in each direction. The City is currently widening LinderoCanyon Road east of Via Colinas to accommodate three lanes in each direction. Thewidening of Lindero Canyon Road is consistent with the City's General Plan.

The Lindero Canyon Road Interchange with U.S. 101 was constructed in 1974. US 101 isan interregional freeway. The existing roadway consists of eight mixed flow lanes andauxiliary lanes. The 2010 Route Concept Report indicates that US 101 should consist of

.i eight mixed flow and two HOV lanes. The HOV lanes would be accommodated in themedian of this segment of the freeway so that no outside widening would be necessary.This proposal would not interfere with existing usage of US 101 and would be consistentwith and would not affect its future operations. The Lindero Canyon Bridge wil not requirefurther modification in the future when additional (HOV) lanes are added in the future.

Background

The Lindero Canyon Road overcrossing of US 101 (built in 1974) is located in the southernportion of the City of Westlake Vilage. Westlake Village is located in the Conejo Valley, arapidly growing urban area, approximately 20 miles northwest of the City of Los Angeles atthewestern edge of Los Angeles County. US 101 runs in a generally north-south direction(but east-west through Westlake Vilage) and provides access to the Los Angeles region tothe southeast. Lindero Canyon Road carries traffc both within the Westlake Vilage areaand to and from US 101. The widening of Lindero Canyon Road and on-ramp G-6 would

.'-,

.,

involve excavation for grading and construction of a retaining wal/ along the south side ofthe adjoining Dole Foods Corporation (Dole) property at 5411 Lindero Canyon Road. TheCity of Westlake Village has a cooperative development agreement with Dole and the Stateof California Department of Transportation (CAL TRANS) for improvements along the Dolepropert and the northbound on-ramp to US 101. The City wil acquire a strip along theeastern and southern sides of the Dole property. The strip includes a maximum 8.5 meter(28 foot) width for additional Lindero Canyon Road right-of-way (ROW), and a temporaryconstruction easement of 7.0 meter (22.5 foot) width. Following construction ofimprovements, CAL TRANS will receive and take control of the ROW associated with thelimits of the state highway. The 2010 Route Concept Report states that US 101 at LinderoCanyon Road should consist of eight mixed flow lanes and two HOV lanes. The existingfreeway has eight mixed flow lanes and auxiliary lanes in each direction.

Deficiencies¡.!

A Traffc Analysis Report has been completed for Lindero Canyon Road for existingconditions and the year 2020 with and without traffc improvements.1 A total of fourintersections included in the report were:

A review of Table 3 indicates that the actual total accident rates are less than the averagerates expected for the locations indicated along Undero Canyon Road. It is expected thatwidening Lindero Canyon Road at these locations wil not increase the actual accidentrates and would instead lower future accident rates by reducing future traffc congestion.

B. PROJECT DESCRIPTION

ALTERNATIVES ANALYSIS

This section describes the alternatives considered for the project: No-build (Alternative A),'. La Tienda Road extension alternative (Alternative "8), and the Preferred Alternative

. (Alternative C).

No Build Alternative - Alternative A

Alternative A, the No Build or "No Project" alternative, would result in no wideningimprovements to Undero Canyon Road or associated ramps at the US 101/UnderoCanyon Road Interchange. While this alternative would result in no construction-relatedimpacts, this alternative would not be consistent with local planning. This alternative doesnot address future traffc deficiencies resulting from continued growth and increasing traffclevels. As indicated in Table 1, three of the four intersections studied are projected tooperate at Levels of Service (LOS) E and F for the year 2020 "no build" alternative.

La Tienda Road Extension - Alternative B

This alternative consisted of the extension of La Tienda Road from Via Rocas to UnderoCanyon Road, intersecting Lindero across from the U.S. 101 Northbound Off-ramp. The

City of Westlake Village Lindero Canyon Road at US 101r_~":_J ("... _~_ _ no .__

niI\

-L

northbound direct on-ramp would be widened to two lanes and depressed under the LaTienda Road extension. Preliminary geometnc design identifed significant design issues,most notably prohibitively high retaining wall and structure costs. Reasons for these highcosts included the high retaining walls required to provide vertical clearance on the on-ramp and the long structure necessitated by sight distance requirements along the on-rampcurVe. In addition to its economic infeasibilty, this alternative would also require moreright-of-way than the preferred alternative, would present drainage diffculties due to thedepth of the depressed on-ramp (potential need for pumping stormwater, with associatedconcerns regarding maintenance and safety in the event of pump failure), and would resultin a less-aesthetically pleasing project (very high retaining wal/s and overhead structures).

,¡

The City of Westlake Vilage (City) proposes to widen Lindero Canyon Road and Ramp G-6 at U.S. Highway 101(US 101) (K.P.59.55/61.15) (See Figure 1, Location Map). Theproposal to reconstruct and widen portions of Lindero Canyon Road and ramp G-6 wasgenerated by the projected Year 2020 traffc deficiencies as summarized in the combinedProject Study ReporUProject Report, Section 6, Traffc and Accident Data and WPA TraffcEngineering, Inc, US 101- Undero Canyon Road PSR Traffc Analysis, April, 1997. Thepreferred alternative comprises a significant portion of the project identified as ProjèctLA960142 in the Federal Transportation Improvement Program. In addition, the project isthe central element of the Congestion Management Program Deficiency Plan for the City ofWestlake Vilage, as approved by the Los Angeles County Metropolitan TransportationAuthority. The project has also been designated as a High Priority project (Project No.0065) under the Transportation Equity Act of the 21st Century (TEA-21), with Federal

funding in the amount of $236,000. The balance of the project funding wil be provided bylocal funds.

It is proposed to widen Lindero Canyon Road between Via Colinas to the north of US 101and Agoura Road to the south from two lanes to three lanes in each direction. The bridgeovercrossing would not require widening. Proposed improvements include the widening ofthe west side of Lindero Canyon Road and the northbound on-ramp (G-6) to US 101. Theconstruction project wil extend from Via Colinas to Agoura Road, a distance of 750 meters(2,450 feet). The City proposes to construct this alternative in two phases for fundingreasons. . Phase 1 would involve reconstruction and widening of Lindero Canyon Road toaccommodate three lanes in each direction and a bikepath. Phase 2 would involve thewidening of Ramp G-6 to two lanes (Please refer to Figures 2a through 2f, Phase 1Layouts and Cross Sections, and Figures 29 through 2i, Phase 2 Layouts and CrossSections).

Based on the descriptions of the relevant resources in Section C (Affected Environment),and the predicted effects of the preferred alternative in Section D (Environmental

Evaluation), the preferred alternative (Alternative C) represents the best choice to reduceexisting and projected future congestion levels. It is also the best choice to reducecongestion-related accidents in the project area by enhancing capacity and mobility alongLindero Canyon Road.

Phase 1 - Lindero Canyon Road Widening

Traffc Signals

Existing traffc signals at the Lindero Canyon Road intersections with Via Colinas, AgouraRoad and the freeway ramps would require construction modification.

. iNon-Standard Design Features

There is one non-standard advisory feature associated with this proposal. This proposalprovides for a varying median width with a minimum width of 1.1 meters (3.6 feet). Topic308 - Cross Sections for Roads Under Other Jurisdictions; 308. 1 City Streets and CountyRoads, Caltrans Highway Design Manual, requires that conventional highway designstandards be incorporated in a project. The conventional highway design standards formedian widths are identified in Topic 305 - Median Standards; 305.1 Width: (2)

Conventional Highways, Caltrans Highway Design Manual, which states that the minimummedian width for city street conditions should be 3.6 meters (11.8 feet). The projectprovides for a 1.1 meters (3.6 feet) minimum median width for Lindero Canyon Road whichis a non-standard design feature. A Fact Sheet, completed to justify the exception for anonstandard median width, has been approved by Caltrans.

C. AFFECTED ENVIRONMENT

Location

The Lindero Canyon Road overcrossing of US 101 (built in 1974) is located in the southernportion of the City of Westlake Vilage. Westlake Vilage is located in the ConejoValley, arapidly growing urban area, approximately 20 miles northwest of the City of Los Angeles atthe western edge of Los Angeles County.

Topography

The topography of the project area is nearly flat about 950 feet above sea leveL. Drainageis from north to south via groundwater flow. The east side of Lindero Canyon Road has noimprovements other than signs and traffc signals. Vegetation includes annual grasses andweeds, oak trees and oleanders. Improvements along the west side of Lindero CanyonRoad, adjacent to the Dole property, include a sidewalk, a section of retaining wall, signsand traffc signals. A short slope above the retaining wall extends to a chain link fence

surrounding the relatively level area of the Dole property which is currently undergoinggrading for construction of the Dole World Headquarters. The slope is vegetated withseveral types of trees and sparse annual grasses and weeds. The level area of the Doleproperty is at approximately the same grade as the top of on-ramp G-6. The retaining wallextends south along Lindero Canyon Road to approximately 600 feet south of

Via Colin asbeyond which there is no retaining wal/, and the south side of the Dole propert slopesmoderately steeply from the fence line to on-ramp G-6. This slope is well vegetated withannual grasses and weeds as well as various shrubs and trees, including oleanders, palmsand pines most of which are located along the fence line.

Land Use

The existing General Plan designation for the property on the northwest quadrant of theLinderQ Canyon Road/U.S. 101 interchange is Offce Commercial; in the northeastquadrant, Specific Plan (Commercial); in the southwest quadrant, CommercialRecreational; and in the southeast quadrant Offce CommerciaL. Land uses within thevicinity ofthe project include the Dole corporate headquarters (northwest quadrant); vacantland and a cemetery (northeast quadrant); a golf course and clubhouse (southwestquadraht); and offce/industrial buildings (southeast quadrant).

Biological Resources

'I

The areas adjacent to Lindero Canyon Road, south of Via Colinas, consist largely of bareearth and patches of weeds and grass. Some native vegetation exists along this portion ofLindero Canyon Road but there is no significant amount of native plant species on eitherside of the road. The east side of Lindero Canyon Road has no improvements other thansigns and traffc signals. Vegetation includes annual grasses and weeds, oak trees andoleanders. Improvements along the west side of Lindero Canyon Road, adjacent to theDole property, include a sidewalk, a section of retaining wall, signs and traffc signals. Ashort slope above the retaining wall is vegetated with several types of trees and sparseannual grasses and weeds. The south side of the Dole property slopes moderately steeplyfrom the fence line to the Lindero Canyon Road on-ramp to northbound US 101. Thisslope is well vegetated with annual grasses and weeds as well as various shrubs andtrees, including oleanders, palms and pines, most of which are located along the fenceline. Some native vegetation exists along roadway embankments and within the interior ofthe interchange loop ramps where Lindero Canyon Road crosses over U.S. 101. Areasadjacent to and within the loop ramps are also heavily landscaped with non-native plantspecies which are part of the freeway planting which occurred when the interchange wasfirst constructed.

Pacifc Southwest Biological Services conducted a search of the California Department ofFish and Game's Natural Diversity Data Base (NDDB) in May, 1997 to determine if anyrare, threatened, or endangered plant or animal species are known to exist in theimmediate vicinity of the project site. The database indicated that the following resourcesare within the region: Santa Susanna Tarplant (Hemizonia minthomiij, Lyon's Pentachaeta(Pentachaeta Iyoniij, Bank Swallow (Riparia riparia) and the Western Pond Turtle (Clemysmarmorata pallda). The following sensitive habitats also occur in the region: SouthernCoast Live Oak Riparian Forest, Southern Sycamore Alder Riparian Woodland and ValleyOak Woodland.

Cultural Resources

A standard archaeological records check and literature review was completed for theproject by EIP Associates in May 1997. The records check and literature review showedthat fourteen cultural resource studies have been conducted in Los Angeles County andten within Ventura County within one mile of the project site. Of these, ten containidentified cultural resources but none of the ten are within the current Area of PotentialEffects (APE). The majority of the APE has been addressed by cultural resourceCity of Westlake ViiageInital StudyÆnvironmental Assessmßnt 18

investigations between 1969 and 1996. The areas not surveyed or addressed are locatednorthwest of the Lindero Canyon Road overcrossing between US 101 and Via Colin as andbetween Lindero Canyon Road and Via Rocas.

i Hazardous Waste

An Initial Site Assessment (ISA) Report has been completed for this proposed project. Ofthe hazardous waste sites or otherwise environmentally impacted sites present in thevicinity of the study area, only the Dole property appears to have adverse environmentalimpacts with potential to affect the project area. A plume of groundwater contaminationconsisting of dissolved chlorinated volatie organic compounds (VOCs) in concentrationsexceeding the Maximum Contaminant Limit extends south from the Dole propertapproximately centered on the Lindero Canyon Road on-ramp to northbound US 101.

Waterways and Hydrologic Systems

The nearest natural, unchannelized watercourse to the project site is Lindero Creek, whichis located over a half-mile northeast of the project site. Lindero Creek acts as a naturalflood channel for the area and its 1 OO-year and 500-year floodplains are contained withinthe unimproved channeL. There are no sole source acquifers in the area

Drainage in the project area is currently conveyed to an open trapezoidal channel ownedand operated by the Los Angeles County Flood Control District (PO 728). This channel isaligned parallel to Lindero Canyon Road and extends from the U.S. 101 Freeway toWestlake Lake south of Foxfeld Drive.

Water Quality

Water quality is currently regulated by a General Construction Activity Storm Water permit,issued by the Regional Water Quality Control Board (RWQCB) pursuant to the Clean

'.. Water Act. Provisions of the National Pollutant Discharge Elimination System (NPDES)

establish procedures to protect against water quality impacts resulting from projectconstruction. Provisions underthe General Construction Storm Water Permit require that aStorm Water Pol/ution Prevention Plan (SWPPP) be implemènted to control construction 'site runoff that could potentially degrade water quality.

Air Quality

The Clean Air Act Amendments (CAAs) of 1990 require that transportation plans,programs, and projects which are funded by or approved under Title 23 U.S.C. or theFederal Transit Act (FT A) conform with state or federal air quality plans. The project isidentified in the 1998/99 through 2004/2005 Regional Transportation ImprovementProgram (RTIP), which is in conformance with all applicable State Implementation Plans(SIPs), and with the 1998 Regional Mobilty Element prepared by the Southern CaliforniaAssociation of Governments (SCAG). Assumptions used in the FY 1998/99 through 2004-2005 RTIP regarding population, employment, travel and congestion were the most recentdeveloped by SCAG for the 1998 RTP, and included the most recently approved planningassumptions by SCAG's Regional CounciL.

E. DISCUSSION OF ENVIRONMENTAL EVALUATION

1. Some minor modification of the existing topography will be required to implementthe proposed project. Landform modifications would consist of the minor grading ofcut and fill slopes (1:2 or flatter) to accommodate intersection improvements,including a wider bike lane. Interchange improvements at the U.S. 101overcrossing would consist of minor cut and fill to increase the width of existing on-

. and off-ramps. Because the land in these areas is vacant, is owned by the City,and was originally designed to accommodate future widening, very little landformmodification would be required to accommodate the proposed improvements.

Excavation for grading and construction of retaining walls along the east and southsides of the adjoining Dole Foods Corporation (Dole) property at 5411 LinderoCanyon Road would be required to accommodate the widening of Lindero CanyonRoad and on-ramp G-6.

4. As is typical of all of southern California, the project site is subject to ground shakinggenerated by periodic seismic activity. Fracturing and displacement of the groundsurface can occur during an earthquake along a causative fault and also as a resultof sympathetic movement on zones of weakness such as older trace faults.However, no such faults have been identified in the project area so no significantimpact is anticipated.

The potential for seismic ground-shaking in the project area is expected to besignificant but the intensity of the shaking is expected to be moderate.2 Seismichazards and the design implications for the project wil/ be addressed in the

'foundation report which wil be prepared for the project. All structures wil bedesigned in accordance with Caltrans current standard seismic load conditions andthe most recent Uniform Building Code, as amended by City Ordinance.Compliance with these standards wil be enforced through plan review and

inspections during construction. Compliance ofthe project with Code requirementswil reduce impacts from ground shaking to a less than significant leveL.

During project construction, ground disturbance wil temporarily increase thepotential for soil erosion. Soil erosion also could be caused by either water or wind.In addition, the project site is within a zone of soils with high shrink-swell potential.3Existing State and City requirements and standard engineering practices wouldreduce impacts to a less than significant leveL. Construction plans wil need tospecify measures for controllng erosion at the project site.

7. The project would use a variety of widely available non-renewable materials forconstruction of the widened road and bíidge including aggregate, asphalt, iron andrelated minerals used in steel, mineral oil and fuel to power construction vehiclesand equipment. Project construction and operation would not involve the wastefuluse of non-renewable resources. No impact would occur.

9. Project construction activities, including disposal of construction waste, wil need toconform to all applicable regulations regarding hazardous waste, solid waste, andlitter control. An Initial Site Assessment (ISA) Report has been completed for thisproposed project. Of the hazardous waste sites or otherwise environmentallyimpacted sites present in the vicinity of the study area, only the Dole propertyappears to have adverse environmental impacts with potential to affect the projectarea. A plume of groundwater contamination consisting of dissolved chlorinatedvolatile organic compounds (VOCs) in concentrations exceeding the MaximumContaminant Limit extends off the Dole propert approximately centered on on-rampG-6. Considering that groundwater is not anticipated to be encountered duringproject construction, the vac plume is not considered to be of concern. Ifgroundwater is encountered during construction and dewatering is necessary, theeffuent generated would require containerization and off-site disposal or treatmentand discharge on-site upon regulatory approval of appropriate permits. Potentialsoil impacts along the portion of the project area at the Dole property are probablyrestricted to very localized occurrences along the sanitary sewer line. If excavationof the sewer line is conducted, there is a low to medium potential of encounteringsoil affected by chlorinated VOC, which would require special management. Alongon-ramp G-6, there is a medium to high potential of encountering soils impacted byaerially deposited lead. Such soils require special management under a varianceissued to CAL TRANS by the DSTC. It is recommended to perform testing for leadin accordance with latest policies during the design phase. If surface leadcontamination is found it is believed that it can be properly disposed of within the fillareas of the project. The project is not expected to result in the generation of anyhazardous waste or other waste products requiring special handling and disposaL.However, if the hazardous materials discussed above are encountered, thefollowing mitigation measures would reduce environmental impacts to a less thansignificant level:

If groundwater is encountered during construction and dewatering isnecessary, the effluent generated shall be containerized and disposed of off-site or be treated and discharged on-site after regulatory approval ofappropriate permits.

If excavation of the sewer line is conducted and soil affected by chlorinatedVaG is encountered, the affected soil shall be containerized and disposed ofoff-site or be treated' and discharged on-site after regulatory approval ofappropriate permits.

:-j

Soils along on-ramp G-6 shall be tested for aerially deposited lead inaccordance with latest policies during the design stage of Phases 1 and 2. Ifsuch soils are found, they shall be properly disposed of in accordance withthe special management requirements of a variance issued to CAL TRANSby the DSTC.

11.

The nearest natural watercourse to the project site is Lindero Creek, which islocated over a half-mile east of the project site. The proposed improvements wilnot have any effect on Lindero Creek. There is, however, an open trapezoidalchannel owned and operated by the Los Angeles County Flood Control District(PD728) in the project vicinity. This channel is aligned parallel to Lindero Canyon Roadand extends from the U.S. 1 D1 Freeway to Westlake Lake south of Foxfeld Drive.Drainage in the project area is currently conveyed to this channeL. Although theAgoura Road Bridge over the channel wil be widened to provide for an additionalturn lane, the proposed project wil not alter existing drainage facilities or historicdrainage patterns. Work on the bridge, however, may potential/y impact waterquality in the drainage channeL. See response to No. 12, below.

Lindero Creek, over a half-mile east of the project site, acts as a natural floodchannel for the area and its 1 DO-year and 500-year floodplains are contained withinthe unimproved channeL. The proposed ramp and roadway widening improvementswil not encroach upon this flood channel area.4 A Floodplain Evaluation Report

would, therefore, not be required for this project.

12. The widening of Lindero Canyon Road and on-ramp G-6 would disturb more thanfive acres and would increase the amount of impervious surface in the project areathus slightly decreasing the absorption rate and slightly increasing the amount ofsurface runoff. The runoff however would fol/ow existing drainage patterns and thechanges in absorption rate and surface runoff are considered to be less thansignificant impacts.

During construction, there is the potential for discharge into the drainage system,and thence to Lindero Creek, of construction related materials. Also, duringoperation of the widened Lindero Canyon Road and on-ramp G-6, there is thepotential for an increased discharge of automotive related materials into the creek.A General Construction Activity Storm Water permit, issued by the Regional WaterQuality Control Board (RWQCB) pursuant to the Clean Water Act, wil be required toimplement the provisions of the National Pollutant Discharge Elimination System(NPDES). Provisions under the General Construction Storm Water Permit requirethat a Storm Water Pollution Prevention Plan (SWPPP) be implemented to controlconstruction site runoff. Required compliance with these provisions wil ensure thatconstruction impacts on water quality would be at a less than significant leveL.

The project would not cause changes in the quantity of ground waters, eitherthrough direct additions or withdrawals, or through interception of an aquifer by cuts

or excavations or through substantial loss of groundwater recharge capabiliy.

17. Air pollutants would be generated during project construction, primarily fromconstruction vehicle emissions and fugitive dust caused by earth disturbance.Construction emissions are expected to be typical of a project of this type and nounusually high levels of pollutants are expected to be generated by constructionactivities. The project area and amount of earth moved would be less

than theSouth Coast Air Quality Management District (SCAQMD) screening threshold ofsignificance so impacts would be less than significant and no mitigation would berequired. Following project completion, air quality is expected to improve due toimproved tràffc flow over the widened roadway.

19. See No. 17 above. Although temporary in nature, the generation of particulatematter in excess of State and local standards is a common concern withconstruction projects. However, due to the limited amount of grading required forthe proposed project, it is not anticipated that emission standards for particulateswil be exceeded.

20. Construction activities would cause temporary, localized increases in noise and

vibration levels. The noise and vibration associated with construction activity areunavoidable and it is possible that noise generated by project construction wouldequal or exceed established noise standards. However, the exceedance of noisestandards is not considered significant because no noise-sensitive uses such asresidential neighborhoods, schools, day-care facilties, hospitals or nursing homesare located in the project area. If the project exceeds noise standards, the followingmitigation measure shall be implemented:

To reduce noise levels below the established noise standards of the City of

Westlake Village, the project shall comply with the special provisions of theCity's noise ordinance addressing construction noise, including provisions forlimitng hours of construction in order to reduce adverse effects on sensitvereceptors.

21. It is possible that noise generated by project construction would equal or exceed

established noise standards. The City of Westlake Vilage's noise regulationscontain special provisions addressing construction noise, including provisions forlimiting hours of construction in order to reduce adverse effects on sensitive.receptors. See No. 19 above.

23. The areas adjacent to Lindero Canyon Road, south of Via Colinas, consist largely ofbare earth and patches of weeds and grass. Some native vegetation exists alongthis portion of Lindero Canyon Road but there is no significant amount of nativeplant species on either side of the road. The east side of Lindero Canyon Road hasno improvements other than signs and traffic signals. Vegetation includes annualgrasses and weeds, oak trees and oleanders. Improvements along the west side ofLindero Canyon Road, adjacent to the Dole property, include a sidewalk, a sectionof retaining wall, signs and traffc signals. A short slope above the retaining wal/ isvegetated with several types of trees and sparse annual grasses and weeds. The

south side of the Dole property slopes moderately steeply from the fence line to on-ramp G-6. This slope is well vegetated with annual grasses and weeds as well asvarious shrubs and trees, including oleanders, palms and pines,most of which arelocated along the fence line. Some native vegetation exists along roadway

embankments and within the interior of the interchange loop ramps where Lindero. Canyon Road crosses over Ü.S. î ûî. Areasaåjacent to and within the ioop rampsare also heavily landscaped with non-native plant species which are part of thefreeway planting which occurred when the interchange was first constructed. Nosignificant amount of native or non-native plant species would be lost due toconstruction of the proposed roadway improvements.

Pacific Southwest Biological Services conducted a search of the CaliforniaDepartment of Fish and Game's Natural Diversity Data Base (NDDB) in May, 1997to determine if any rare, threatened, or endangered plant or animal species areknown to exist in the immediate vicinity of the project site. The database indicatedthat the following resources are within the region:

Santa Susanna Tarplant (Hemizonia minthornii)Lyon's Pentachaeta(Pentachaeta Iyonii)Bank Swallow (Riparia riparia)Western Pond Turtle (Clemys marmorata pallda)

The fol/owing sensitive habitats also occur in the region:

.'

Because of the characteristics of the project site, the habitat requirements ofspecies, and the hydrological conditions of the site, PSBS concluded that there isno possibilty of any of these resources occurring at the project site. No significantamount of native plant species would be lost due to constmction of the proposedramp and roadway improvements.

. - southeast quadrant of the interchange would be removed. The top of the slopewould be widened to provide space for the bikepath proposed for Phase 1. It isproposed to construct a new irrigation system and to replace the landscaping. Thefollowing mitigation measure shall be implemented:

Native plant species shall be used to revegetate embankments and roadwayedges. Planting and hydroseeding is rccommcnded shall be to be utilized forerosion control purposes.

City of Westlake Vilagelroil;..' C"h.,..,J'....:.._____.._. JI_____ Lindero Canyon Road at US 101

27. Some isolated patches of vegetation (primarily along roadway embankments) wouldbe destroyed by the proposed project. It is possible that these areas provide limitedhabitat for some species. However, because of the small, isolated, and degradedcondition of these areas, any loss of habitat wil be insignificant.

2ô. Aithough considered minimai, the vegetation aiong the rõadway edge may have

some limited habitat value (see No. 27 above). However, the project would affectsuch a small and isolated area of degraded habitat that any loss would beinsignificant. As a result, the limited loss of species that might occur would not havea significant effect on the diversity of animal species in the area.

29. There are two bridges within the project area. the Lindero Canyon Bridge and the

AQoura Road Bridge. which could potentially provide habitat for bats and/or cliffswallows. In addition. there are vegetated areas within the project footprint thatcould additionally provide nestin~ habitat for other native birds. Consequently. a pre-construction survey should be conducted for breeding bats and swallows ana asimilar survey should be conducted for nesting birds. Implementation of thefol/owing mitigation measure would result in a less than significant impact:

If project activities are to occur during the nesting season of birds (March 1 toSeptember 1), a pre-construction survey for breeding bats and swallows andother nesting birds shall be conducted per California Department of Fish andGame guidelines. A buffer of at leàst 150 feet for construction activities shallbe maintained for any active bird bests (500 feet for raptor nests).

32. Acquisition of right-of-way would not be required for the Phase 1 work. The project

would, however, require the acquisition of a portion of the Dole property alongLindero Canyon Road and on-ramp G-6 for the Phase 2 work. The City of WestlakeVilage has a cooperative development agreement with Dole and the State ofCalifornia Department of Transportation (CAL TRANS) for improvements along theDole propert and the northbound on-ramp to US 101. The City wil acquire a stripalong the eastern and southern sides of the Dole propert. The strip includes amaximum 8.5 meter (28 foot) width for additional Lindero Canyon Road right-of-way(ROW) and a temporary construction easement of 7.0 meter (22.5 foot) width.Following construction of improvements, CAL TRANS wil receive and take control ofthe ROW associated with the limits of the state highway. This acquisition would beconsistent with the General Plan designation of Lindero Canyon Road and wouldhave no impact on the designated uses. The property required for right-of-way iscurrently vacant and its land use designation is commerciaL. A Right-of-Way DataSheet has been prepared for this project.

33. The project is consistent with the City of Westlake Vilage's General Plan and thedesignation of Lindero Canyon Road as a major arterial highway.

35. The project does not involve the construction or demolition of housing and would,therefore, not affect regional or local population projections. The project wouldenhance access between areas along Lindero Canyon Road to US 101 and thenceto other parts of California. However, the enhanced access would be insufficient to

City of Westlake Vilage Undero Canyon Road at US 1011",;li..1 C'1.."J.,IC..,'o"',.........l-..I JI..........._....10 1___..____.&_

induce substantial growth in the project area and would have a less than significantimpact.

38. The project concerns the widening of an existing street and freeway access rampsin an area zoned for industrial and commercial uses. There would, therefore, be noåisruption or åivision or the physicai arrangement of an existing communiry

40. The proposed project would generate temporary construction employment and is

expected to have a positive effect on local industry and commerce by eliminating aprojected roadway deficiency which hampers circulation in the area.

41. The project is not expected to have a direct effect on propert values or the local taxbase; however, the elimination of circulation deficiencies would remove oneconstraint to growth in the area, thereby enhancing the potential for future growth inpropert values and the local tax base.

43. A review of utilty atlases indicates that this project would have no impact on utilities.The City of Westlake Vilage wil prepare the Certification of Utiliy Facilities. Duringconstruction, temporary road closures may cause emergency response fire andpolice protection vehicles to take alternative routes thus increasing response timesand interfere with emergency response and/or emergency evacuation plans.Implementation of the following mitigation measure would result in a less thansignificant impact:

The applicant shall consult with local police, fire and other emergencyservice providers to develop temporaryaltematives to the use of LinderoCanyon Road as an emergency response or evacuation route during projectconstruction.

Once completed, the project, by widening Lindero Canyon Road and improvingtraffc. operation, would improve emergency response times and enhance firepiOtection. The project would not result in the need for new or altered fire andpolice protection services.

The project would increase the impermeable surfaces of Lindero Canyon Road andcreate additional run-off to the local storm drainage system. Site run-off would notexceed the capacity of the storm drains serving the site. Therefore, the projectwould have a less than significant impact on storm water infrastructure.

The project would require solid waste disposal service only during construction.The construction contractor would remove all solid waste from the site. Duringproject operation, waste would be removed by the road-sweeping service thatcurrently clears Lindero Canyon Road. There would be no impact on solid wastedisposal services

The project would use a small amount of water during construction which can besupplied by existing water services and which would not have a substantial impacton local or regional water supplies. During operation, the project would not use any

City of Westlake Vilage Lindero Canyon Road at US 101. .

water. Therefore, there would be no impact on local or regional water supplies.

,. ,

44. The proposed project wil not significantly impact existing transportation systems oralter present patterns of circulation. Instead, the proposed improvements wilimprove traffc circulation along Lindero Canyon Road and improve traffc safety atthe ûn-ramp access for ÜS Î û1. During construction, detours may be necessarythereby having a temporary impact on interchange circulation. Provision of signsnotifying the public of pending construction and ramp closures would be adequatenotification for this project. Traffc that would normally use the interchange atLindero Canyon Road may instead utilze the next interchanges to the north andsouth. These conditions, however, would be temporary and would be alleviatedupon completion ofthe project. Overall, the project would improve traffc circulationin the project area and be beneficial for the community.

)

The proposed project wil improve pedestrian circulation and safety by providingconnecting sidewalk improvements where none currently exist. Although pedestrianvolumes have been and are expected to remain relatively low, the proposedsidewalk faciliies wil improve safety and should adequately serve future needs.

45. During project construction, vehicle trips would be temporarily increased byconstruction-related trips and traffc congestion would be temporarily increased byintermittent lane closures due to construction during active construction times. Thiswould be a less than significant impact.

The project is designed to accommodate traffc generated by planned growth.Project operation would not generate vehicle trips or promote traffc congestion.

, 48. The project is not anticipated to involve the risk of an accidental explosion but the

! accidental release of hazardous substances is possible during project construction.Compliance with federal, state and local regulations concerning hazardous solid andliquid waste would ensure that the impact would be less than significant.

51. A standard archaeological records check and literature review was completed for

the project by EIP Associates in May, 1997. The records check and literaturereview showed that fourteen cultural resource studies have been conducted in LosAngeles County and ten within Ventura County within one mile ofthe project site. Ofthese, ten contain identified cultural resources but none of the ten are within thecurrent Area of Potential Effects (APE). The majority of the APE has beenaddressed by cultural resource investigations between 1969 and 1996. The areasnot surveyed or addressed are located northwest of the Lindero Canyon Roadovercrossing between US 101 and Via Colinas and between Lindero Canyon Roadand Via Rocas. The lack of identified cultural remains for the rest of the APE andthe majority of the study area indicate that the project site is of low sensitivity forhistoric cultural resources and of low to moderate sensitivity for prehistoric culturalresources. As recommended by EIP Associates, the area northwest of the LinderoCanyon Road overcrossing (and within the APE) was subjected to anarchaeological reconnaissance survey and other areas of immediate impact

received a cursory survey for current conditions. The recently completed

City of W.estlake Viiage Lindero Canyon Road at US 101In;lj~' Cl..,..~/C"".li...._....¡,_1 A....______J. . .

archaeological records check need not be repeated and a Negative HPSRdocument, adequate for compliance, is included in the PSR/PR as Attachment A.

The following mitigation measure shall be implemented:

If buried historic or prehisroric resources are round during ine excavarionactivities, Excavation activites shall be halted and an archaeological monitorshall be retained to formally evaluate such resources for their signifcanceand/or imporlance pursuant to CEQA.

..

54. Construction activities wil generate temporary air pollutant emissions, dust, noise,and vibration. Project construction may also temporarily hamper access andnecessitate traffc detours. Access and traffc detour alternatives wil need to beincorporated into project construction plans. See nos. 16, 19, 20, and 42 above.

L. COMMENTS RECEIVED AND RESPONSES TO COMMENTS

The Draft Initial Study/Environmental Assessment was circulated for public and agencyreview from May 3. 2001 through June 18. 2001.

The foilowing letters were received from reviewing agencies:

1. Letter from C.F. Raysbrook. Regional Manaqer. California Department of Fish andGame. South Coast Region. June 19. 2001.

Letter No.1 - California Department of Fish and Game. South Coast Region

Comment #1: The California Department of Fish and Game (CDFG) indicates that the twobridges within the project area. the Lindero Canyon Bridge and the Agoura Road Bridge,could provide habitat for bats and/or cliff swallows and. that vegetated areas within theproject footprint could additionally provide nestinq habitat for other native birds. The CDFGrecommends that a pre-construction survey be conducted for breeding bats and swallowsand that a similar survey be conducted for nestinq birds. A buffer of at least 150 feet fromactive bird nests (500 feet for raptor nests) is recommended to be maintained.

Response: The following mitigation measure will be added to the project to respond tothese concerns:

Bioloqical Resources

If project activities are to occur during the nesting season of birds (March 1 toSeptember 1). a pre-construction survey for breeding bats and swallows and othernesting birds shall be conducted per California Department of Fish and Gamequidelines. A buffer of at least 150 feet for construction activities shall bemaintained for any active bird bests (500 feet for raptor nests).

Comment #2: The CDFG requests clarification of potential impacts to water quality in thedrainage channel adjacent to the construction site, including indirect impacts todownstream wildlife and wildlife habitat.

Response: There is minimal potential for construction activities to affect water quality inthe drainage channeL. Although the Agoura Road Bridge over the channel wil be widened,project conformance with applicable National Pollutant Discharge Elimination (NPDES)requirements and implementation of a Storm Water Pollution Prevention Plan (SWPPP) wiladequately mitigate potential impacts to water quality in the channeL.

Comment #3: The CDFG recommends including other feasible mitigation measures tomitigate pollutant run-off in addition to compliance with a Storm Water Pollution PreventionPlan (SWPPP).

Response: As indicated in the Draft Initial Study/Environmental Assessment. the projectwil be required to obtain a General Construction Activity Storm Water permit. issued by theRegional Water Quality Control Board to implement the provisions of the National PollutantDischarqe Elimination System (NPDES) for the project. In addition. the project wil berequired to implement a Storm Water Pollution Prevention Plan (SWPP) to controlconstruction-related runoff. These measures should be adequate in addressinq potentialwater quality impacts:

A mitigation measure exists (Mitiqation Measure No.5) which requires native plant speciesbe used to revegetate embankments and roadway edges and recommends that plantingand hydroseeding be implemented for erosion control purposes. This mitigation measurewil be revised to address CDFG's concerns as follows:

Biological Resources

Native plant species shall be used to revegetate embankments and roadway edges.

Planting and hydroseeding is recommended shall be utilzed. for erosion controlpurposes.

Comment #4: The CDFG expresses concerns that the project may affect a streambed andthat a Streambed Alteration Agreement may be needed for the project.

Response: The project will not cross a streambed and there will be no alteration to anexistinq streambed. Therefore, a Streambed Alteration Agreement wil not be needed.
