CLARIFICATIONS AND REVISIONS
Minor revisions have been made to the Plum Canyon County Park Project Draft Initial StudylMitigated Negative Declaration (ISIMND). These revisions have not resulted in a change in analysis and/or conclusions of the Final ISIMND. This section identifies the changes to the document that resulted from public comments on the Draft ISIMND. Deleted text is shown with an overstrike, and new text is bold, as presented below. The Final ISIMND reflects these revisions and text changes and is shown without the redlined text.
Since the circulation of the Draft ISIMND, KEA Environmental, Inc. has merged with EDAW, Inc. All references toKEA Environmental in the document have been changed toEDAW.
The following is added at the end of the first paragraph onpage 1-1of the Draft IS/MND:
This Final IS/MND also presents revisions t~ Section 3.IV., Biological Resources, and Section 3.XIII., Public Services(Fire Protection), in response to someofthe written comments (seeSection6.0)receivedon ' the Draft ISIMND,which was circulated for public and governmental agency review from February 13, ,.2001through March 14,2001, and the Mitigation Monitoring and Reporting Program (seeSection7.0).
Mr. Larry Hensley's telephone number listed under "3. Contact Person and Phone Number:" on page 2-1 of theDraft ISIMNDischanged as follows:

high water mark," which d~rtl5-deAnesis defined, in part, as a "destruction of terrestrial vegetation" (e.g., the lack of vegetation within portions of the drainage that was observed during site reconnaissance). Analvsis of these drainages bv the U.S. "mw Coros of Engineers (Corps) determined that they did not f.'lllwithin the Corps' regulatorv jurisdiction; therefore. no federallv protected wetlands would be affected bv the proposed project.
Howcver, the Califomia Department of Fish and Game (CDFO) conducted a separate field analvsis and detcmlined that it would take regulatory jurisdiction over the channels. These drainages were typically bare; some areas at the bottom of the channel support non-native grasses. These two drainages merge to form a wider and more deeply cut "waters of th~ntled-SttttesCDFG-jurisdictional" area (three to Ave teet wide). These drainages begin in the vicinity of the proposed tot lot and group pienic areas; and extend to the south. +I!e-Y:& AAllYCorpsof F.ngineers (Cofl~ntaeted-regardtng the proposed projeet and the idell~rainages; the GOFpS-has-<letennined-that-tlle-pmposed-pffijeet-wouk!-notdischalb~re4ged-or-A"-materials-int~teF-ef4he -lJffi1e4-States" or lllHtdjacem-wetland.--Additi&na~e drainages on site are considered "isolated waters" (deAned-b;:-the-GortlS-as...:':nollllawi,'tlble,isolated, [and] intrMtate").

Since these drainages total less than one fourth-tenth of an acre, impacts arc anticipated to be less than significant but would require mitigation at a 1.5to I ratio (1.5acres of mitigation for each acre of impact) in order to complv with the "no net loss" policv of CDFG. The total area of impact associated with the CDFG jurlsdlctlonal drainages on site is 0.046 acre; therefore, based on the 1.5:1 mitigation r:Jtio, 0.069 acre of mitigation would be required.
The disturbed coastal sage scrub habitat continues off-site along the relatively flat topography to the cast. Within this adjacent off-site area is a sandy wash, which would qualify as another ""taters of the United-States;!:CDFG jurisdictional drainage, as shown in Figure 7. This wash is also associated with small patches of riparian vegetation in the form of mule fat scrub (Bacclzarissalicifolia). Sandy wash habitat within the region is suitable for the federal and state-listed endangered slender-homed spineflower (Dodecahemaleptocerast. As currently designed, the proposed project would not impact the wash, and, therefore, no impacts would oceur to any population of slender-homed spineflower, or the riparian habitat within the drainage, One salt cedar (Tamarixsp.) occurs off-site from the southeast end of the project area (Figure 7). Intact coastal sage scrub occurs on the slopes to the east of the project site. California sagebrush is the dominant species in this area, with smaller pockets of white sage (Salvia apiana), scrub oak (Quercus berberidifolia), and buckwheat. The Califomia gnatcatchcr (Po/ioQ1ilacaliwrllica caliwmica), a federally listed threatened species. was not observed during either site reconnaissance visit. However, based on input bv the U.S. Fish and Wildlife Service IUSFWS), focused surveys for the California gnatcateher were recommended for the site and within all suitable vegetation within 300 feet of the proposed development. In response to USFWS recommendations, the County conducted focused surveys for the California gnatcatcher, No coastal California gnatcatchers were observed or detected during any of the focused surveys. The absence of the gnatcatcher may be attributed to the isolated nature of the project site and the high level of urban development in the area.
The disturbed nature or the project site suggests that migratorY bird species would not likely nest within the disturhed coastal sage scruh hahitat on site. However. due to the low potential for bird species covel'ed under the MigratOl'v Bird Treaty Act to nest on site, the Los Angeles County Department of Park and Recreation would "estl'ict all vegetatilm removal of suitable nesting habitat to the non-breeding season {generally September 1through February 281, Nesting habitat for the majority of migratory bird species typically consists of native scrub species within the vicinity of the project site, such as California sagebrush, buckwheat, and white sage.

nesting habitat for most bird species. However, there arc some ground-nesting species that can usc shorter vegetation, such as small shrubs or tall grasses, as protective cover for their nests. As previously stated, the disturbed coastal sage scrub habitat on site (l.e., sub-meter height) does not provide optimal nesting habitat for migratory bird species, particularly when highly suitable habitat occurs off-site to the east. The presence of this off-siteoptimal nesting habitat would likelyresult in the majority ofthe nesting activity to occur in these off-siteareas rather than within the project site.

INTRODUCTION
I
The Initial StudylMitigated Negative Declaration (IS/MND) was prepared pursuant to the requirements of Sections 15063, 15070, and 15071 of the California Environmental Quality Act (CEQA) Guidelines.
This document summarizes and addresses the results of the Initial Study prepared to determine if any significant environmental effects would occur from the proposed development of Plum Canyon County Park in the community of Saugus, immediately outside the boundaries of the City of Santa Clarita, as shown in Figure 1. This Final ISIMND also presents revisions to Section 3.N., Biological Resources, and Section 3.XIII., Public Services (Fire Protection), in response to some of the written comments (see Section 6.0) received on the Draft ISIMND, which was circulated for public and governmental agency review from February 13,2001 through March 14, 2001, and the Mitigation Monitoring and Reporting Program (see Section 7.0).

PROJECT OBJECTNES
The primary objective of the project, as identified by the Los Angeles County Department of Parks and Recreation, is to develop a new park that would provide passive and active year-round recreation opportunities to serve the local residential community. Specifically, the project objective is to provide a local park with a service radius of up to one-half mile.
PROJECT LOCATION
I
I
The project site is located in an unincorporated area of the County of Los Angeles, known as the community of Saugus. The project site, which is approximately 13 acres, is located at 2822 North Via Joyce Drive in a recently developed residential area, immediately east of the City of Santa Clarita boundaries. The project site is bounded by Plum Canyon Road on the south, Via Joyce Drive on the west, residential lots on the northwest, and by a City of Los Angeles Department of Water and Power (LADWP) utility easement on the east.
BACKGROUND
I
I
On November 3, 1992and November 5, 1996,the voters of Los Angeles County approved "Proposition A" assessment measures which provide funding for the Los Angeles County Regional Park and Open Space District to develop and improve facilities to meet the diversified needs of the citizens of Los Angeles Co~nty.

DESCRIPTION OFTHE PROJECT
The proposed project would result in the conversion of approximately 7 of the 13acres of undeveloped land into apassive and active year-round public park; theremaining six acres would remain undeveloped.
The project site is comprised of two relatively flat pads, one in the northern end and the other in the southern end of theproject site; correspondingly, the proposed project would be divided into twophases.
Funding for Phase II is not available at this time; however, for the purpose of this environmental document, PhaseII isassumed tobe implemented immediately following thedevelopment ofPhase I.

6. General Plan Designation: The general plan land use designation forthe site isUrban 1,which allows for low-density
residential development (1.1 to 3.3 unitsper
acre).
7. Zoning: The site was originally zoned as Hillside
Management but later re-classified as
Residential Planned Development (RPD). The
lot is located onTrack No. 37801, whichisa
unit ofparent TrackNo. 31158.
8. Description of Project:
The proposed project would result in the conversion of approximately 7 of the 13acres of undeveloped land into a passive and active year-round public park. The project site is comprised of two relatively flat pads, one in the northern end and the other in the southern end of the project site; correspondingly, the proposed project would be divided into two phases. Funding for Phase II is not available at this time; however, for the purpose of this environmental document, Phase II is assumed to be implemented immediately following thedevelopment of Phase I.

3.0 Discussion of Environmental Impacts and Mitigation Measures I
I
3.0 DISCUSSIONOFENVIRONMENTALIMPACTS
ANDMITIGATION MEASURES
I. AESTHETICS
Would the proposal:
I
I
a) Have a substantial adverse effect on a scenic vista? I
NoImpact. The project site is located in an area characterized bysingle-family residences andscrub covered hillsides (see Figures 3 to 6). The project site occupies an undeveloped lot that is only visible from a few nearby streets and overlooking residences. There are no designated scenic vistas or highways in the immediate vicinity of the project site; therefore, impacts to a scenic vista would not occur. No mitigation measures arerequired.
I
I
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?
I
No Impact. There are over 1,200 miles of State designated scenic highway in California. The nearest State designated scenic highway, Angeles Crest Highway (Highway 2), is located approximately 20 miles southeast of theproject site in the San Gabriel Mountains. The project site is not visible from this or any other designated scenic highway; therefore, no impacts would occur, and nomitigation measures are required.
c) Substantially degrade the existing visual character or quality ofthe site and its surroundings?, .
I Less Than Significant Impact. As shown in Figure 3, the project site is currently undeveloped.
The project site is characterized by two terraces which are separated by a small slope crossing the northern third of the site. The northern or "upper" terrace would be developed under Phase I, whereas the southern or "lower" terrace would remain undeveloped until Phase II. Both terraces would be visible from at least five residences to the north and three residences to the east which overlook the site. The park would also be visible at ground level from numerous residences along Via Joyce Drive, Werren Place, Arthur Court, Adriene Way, and Jerry Place, as shown in Figures 3 andS.

A few acres of disturbed coastal sage scrub habitat would be converted to parkland as a result of the proposed project. The currently undeveloped open space would be replaced with recreational amenities, including a tennis court, basketball court, a multi-purpose field (baseball diamond and soccer field), children's play area/tot lot, picnic area, and other facilities. This would alter the visual character of the project site from its natural condition to a developed, albeit open space, condition.
However, the public park would not' degrade the existing visual character of the site and its surroundings. Public parks are aesthetically consistent with single-family residential communities, such as the neighborhood around the project site. The surrounding hillsides would remain in their current open space condition, providing a natural buffer between the park and the residences to the north and east. Visual impacts would be less than significant; therefore, no mitigation measures are required.

d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?
Less Than Significant Impact. The proposed Plum Canyon Park would have security lighting along the pathways, at the restroom, and in the parking lot. No other nighttime lighting is proposed for the project; therefore, impacts associated with light and glare would be lessthan significant.
II. AGRICULTURE RESOURCES
Would the project:
I a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural usc, or a Williamson Act contract? c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use? I
I No Impact. The project site isnot zoned for agricultural uses. There areno agricultural resources or operations on the project site or on adjacent properties, which are,open space or support residential uses. No landsare enrolled under the Williamson Act. No mitigation measures are required.
I III. AIR QUALITY
I
I
Would the project:
I
I
a) Conflict with or obstruct implementation of the applicable Air Quality Attainment Plan? b) Violate any air quality standard or contribute to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)?
I
Less Than Significant Impact. The project site is located in the Los Angeles County sub-area of the South Coast Air Basin, Los Angeles County is designated as a non-attainment area for ozone (03), carbon monoxide (CO), nitrogen oxides (NO,J, and particulates (PM1o). The South Coast Air Quality Management District (SCAQMD), the regional agency empowered to regulate stationary sources, maintains an extensive air quality monitoring network to measure criteria pollutant concentrations throughout the South Coast Air Basin. The closest air monitoring station is located in the City ofSanta Clarita, approximately fivemiles southwest of theproject site.

Construction Emissions
The SCAQMD's thresholds of significance for the criteria pollutants arc shown on Table 2. Minor air contaminant emissions during the worst-case period, i.e., during construction activities, would result from the use of construction equipment and trips generated by construction workers and haul/material delivery trucks. Construction equipment used for conducting the proposed improvements would primarily consist of one loader, one dozer, one backhoe, one water pump, one concrete pump, one paver, and one truck crane. It is anticipated that up to six months would be required to complete the proposed improvements under Phase I and another six months to complete the proposed improvementsunder Phase II. Project related construction emissions would have a temporary less than significant effect on air quality in the vicinity of theproject (seeTable 3).

Construction equipment would emit nitrogen oxides, carbon monoxide, hydrocarbons, and particulates; ozone is not emitted directly but is a secondary pollutant produced in the atmosphere through a complex series of photochemical reactions involving reactive organic compounds (ROC) , and nitrogen oxides (NO)t). These emissions would increase local concentrations temporarily but would not be expected to increase the frequency of violations of air qualitystandards.

during the entire construction period. In addition, less than five pounds of PMIO would be emitted during the disturbance of approximately three acres of disturbed earth duringPhase I and four acres of disturbed earth during Phase II. As these quantities would not exceed any of the threshold limits presented in Table 2, significant air quality impacts resulting from construction activities are not anticipated tooccur. Mitigation measures would not be required.
OperationEmissions
I
I
I
The proposed project would generate new mobile source emissions associated with the vehicular trips generated by the park facility. No significant air emissions from stationary sources are anticipated (limited to the use of electricity on-site, which is anticipated to be minor). As discussed in Section XV, Transportation/Circulation, the proposed project is anticipated to generate less than 90 trips on any given day. Most of the visitors would be from the neighboring areas and would either walk or bike to the site. The proposed project would not result in significant traffic increases within the project vicinity. There would be no significant impacts to regional air quality anticipated from operation of theproposed project.
I
I
d) Expose sensitive receptors to substantial pollutant concentrations? I
I
I
Less Than Significant Impact. The project site is bordered by sensitive receptors, primarily single family residences, on the west, north, and south. However, as discussed above, the construction impacts associated with the proposed project would be less than significant, and because of their short duration, these impacts are not anticipated to add to long-term air pollution problems. Due to the low level of trips generated by the project, criteria pollutant concentrations are anticipated to be well below the thresholds and, therefore, would not result in a significant impact to sensitive receptors adjacent to the project site. No mitigation measures are necessary. e) Create objectionable odors affecting a substantial number of people? No Impact. No activities would occur and no materials or chemicals would be stored on-site that would have the potential to cause odor impacts during the construction and use of the proposed park facility. Therefore, adverse odor impacts w0':1ldnot occur. No mitigationmeasures arerequired.

IV. BIOLOGICAL RESOURCES
Would the project:
I
a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?
c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? I

3.0 Discussion of Environmental Impacts and Mitigation Measures Less Than Significant Impact. Two biological reconnaissance surveys were conducted by an EDAW, Inc. (EDAW) biologist for the Plum Canyon County Park site on November 15,2000, and April 4, 2001; the latter was conducted to prepare response to comments. The reconnaissance surveys focused on determining the presence or potential for significant biological resources on or adjacent to the site. Vegetation communities and biological resources are documented inFigure 7.
Vegetation on site consists of disturbed coastal sage scrub dominated by deer weed (Lotus scoparius), with scattered individuals of California sagebrush (Artemisia californica), buckwheat (Eriogonumfasciculatumy; and black sage (Salvia mellifera). Native and nonnative plant species interspersed between the native shrub species in this habitat include horehound IMarrubium vulgare), pineapple weed (Chamomilla suaveolens), black mustard (Brassica nigra), red-stem filaree (ErodiulIl cicutariumi, Shepherd's purse (Capsella bursa-pastorisi, clover (Trifolium sp.), Russian thistle (Salsola iberica), goldfields (Last7zeniasp.), popcorn flower (PlagiobotTzryssp.), gazania (Gallzia sp.), pectocarya (Pectocarya sp.), cudweed (Gnaphaltum sp.), and tree tobacco (Nicotiana glaucds., Anarrowband of unvegetated land occurs along the western and southern boundaries of the project site, as mapped inFigure 1.
Due to the disturbed nature of the vegetation on site and the connectivity with housing developments to the north and west, the fauna observed within and adjacent to the project area were typically urban and disturbance-adapted species. Wi1dlife observed on site included western fence lizard (Sceloporus occidentalisy, common raven (Corvus corax), California towhee (Pipilo crissalls), mourning dove (ZenaiDa macroura), Anna's hummingbird (Calypte anna), Audubon's cottontail (Sylvilagus audubon;'), domestic dog (Canisjamiliaris), and small rodent burrows. "
Within the disturbed coastal sage scrub habitat, there are two narrow drainages that have been mapped as "CDFG-jurisdictional areas" due to the presence of a well-defined bed and bank associated with the drainages (i.e., a distinctly incised channel) and the presence of an "ordinary high water mark," which is defined, in part, as a "destruction of terrestrial vegetation" (e.g., the lack of vegetation within portions of the drainage that was observed during sitereconnaissance). Analysis of these drainages by the U.S. Army Corps of Engineers (Corps) determined that they did not fallwithin the Corps' regulatory jurisdiction; therefore, no federally protected wetlands would be affected by the proposed project. However, the California Department of Fish and Game (CDFG) conducted a separate field analysis and determined that it would take regulatory jurisdiction over the channels.
These drainages were typically bare; some areas at the bottom of the channel support non-native grasses. These two drainages merge to form a wider and more deeply cut "CDFG-jurisdictional" area. These drainages begin in the vicinity of the proposed tot lot and group picnic areas and extend to the south. Although the Corps has not taken regulatory jurisdiction on the proposed project, impacts to these drainages would require permits from CDFG and the California Regional Water Quality Control Board (RWQCB) (a 1601 Streambed Alteration Agreement and a 401 permit, respectively). Since these drainages total less than one tenth of an acre, impacts are anticipated to be less than significant but would require mitigation at a 1.5to 1ratio (1.5 acres of mitigation for each acre of impact) in order to comply with the "no net loss" policy of CDFG. The total area of impact associated with the CDFG-jurisdictional drainages on site is 0.046 acre; therefore, based on the 1.5:1 mitigation ratio, 0.069 acre of mitigation would be required. ' The disturbed coastal sage scrub habitat continues off-site along the relatively flat topography to the east. Within this adjacent off-site area is a sandy wash, which would qualify as another CDFG jurisdictional drainage, as shown in Figure 7. This wash is also associated with small patches of riparian vegetation in the form of mule fat scrub (Baccharis salicifolia).

3.0 Discussion of Environmental Impacts and Mitigation Measures the region is suitable for the federal and state-listed endangered slender-homed spineflower (Dodecahema leptoceras). As currently designed, the proposed project would not impact the wash, and, therefore, no impacts would occur to any population of slender-homed spineflower or the riparian habitat within thedrainage.
One salt cedar iTamarixsp.) occurs off-site from the southeast end of the project area (Figure 7).
Intact coastal sage scrub occurs on the slopes to the east of the project site. California sagebrush is the dominant species in this area, with smaller pockets of white sage (Salvia apiana), scrub oak (Querclls berberidifoliai, and buckwheat. The California gnatcatcher (Polioptila californica californicai, a federally listed threatened species, was not observed during either site reconnaissance visit. However, based on input by the U.S. Fish and Wildlife Service (USFWS), focused surveys for the California gnatcatcher were recommended for the site and within all suitable vegetation within 300 feet of the proposed development. In response to USFWS recommendations, the County conducted focused surveys for the California gnatcatcher. No coastal.California gnatcatchers were observed or detected during any of the focused surveys. The absence of the gnatcatcher may be attributed to the isolated nature of the project site and the high level of urban development in the area.
The disturbed nature of the project site suggests that migratory bird species would not likely nest within the disturbed coastal sage scrub habitat on site. However, due to the low potential for bird species covered under the Migratory Bird Treaty Act to nest on site, the Los Angeles County Department of Park and Recreation would restrict all vegetation removal of suitable nesting habitat to the non-breeding season (generally September 1 through February 28). Nesting habitat for the majority of migratory bird species typically consists of native scrub species within the vicinity of the project site, such as California sagebrush, buckwheat, and white sage. Vegetation of at least one meter in height offers the optimal nesting habitat for most bird species. However, there are some ground-nesting species that can use shorter vegetation, such as small shrubs or tall grasses; as protective cover for theirnests. As previously stated, the disturbed coastal sage scrub habitat on site (i.e., sub-meter height) does not provide optimal nesting habitat for migratory bird species, particularly when highly suitable habitat occurs off-site to the east. The presence of this off-site optimal nesting habitat would likelyresult in the majority of the nesting activity to occur inthese off site areas rather than withintheproject Site.
The proposed project would have a less than significant impact on sensitive plant and animal species on site; as previously mentioned, no federally protected.wetlands would be affected by the proposed project. However, the following mitigation/avoidance measures would minimize impacts to the CDFG-jurisdictional drainages that would be eliminated from the project site and impacts to previously unidentified biological resources ifobserved during project construction.
Mitigation Measures
M-IV.l The County shall mitigate impacts tothe CDFG-jurisdictional drainages by contributing to a mitigationfund through the payment of aJee. The mitigationfund shall be used to 'mitigate off-site at an appropriate preserve selected by CDFG. TheJee shall be used to purchase 0.069acres ofmitigation at theselected preserve.

3.0 Discussion of Environmental Impacts and Mitigation Measures disturbance to determine ifnesting birds arepresent. Ifnesting birds are notfound during the survey 011site or within 300feet of the limits of grading, construction activities may proceed. During construction, similar surveys for nesting birds shall be conducted on a weekly basis on site and within a 300-[00t buffer from the limits of construction. !f a nesting bird listed as protected by the Migratory Bird Treaty Act is observed Oil site or withill300feet of the grading limits, all activity within 300feet of the nest shall be halted until it is certain that theyoung havefledged. This measure will ensure compliance with theMigratory Bird TreatyAct.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? .
1) Conflict wittI the provisions of an adopted Habitat Conservation Plan, Natural Conservation Community Plan, or other approved local, regional, or state habitat conservation plan? ' Less Than Significant Impact. The site is bordered by residential development to the north and west andby a major road (Plum Canyon Road) to the south. The site itself is relatively disturbed and doesnot provide optimal habitat forresident or migratory species in theregion. Impacts tomigratory birds would be minimized by restricting vegetation removal of suitable nesting habitat to the non breeding season (generally September 1 through February 28). The location of the project site adjacent to pre-existing development would not substantially interfere with the movement of any wildlife species through the area. Additionally, California's Natural Communities Conservation Plan (NCCP) docs not currently encompass this portion of Los Angeles County, and the County has not designated any portion of the site as part of a County-designated Significant Ecological Area (SEA).
Therefore, the proposed project would not conflict with any local, regional, or state preservation/conservation guidelines. No mitigation measures are necessary.
V. CULTURAL RESOURCES
Would the project:
a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5?
b). Cause a substantial adverse change in the significance of a unique archaeological resource pursuant to §15064.5? .
c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
d) Disturb any human remains, including those interred outside offormal cemeteries? No Impact. EOAW archaeologists conducted an archaeological records search for the project site at the South Central Coastal Information Center. Six archaeological sites, one prehistoric and five historic, were identified within a one-mile radius of the project site. However, no archaeological sites havebeen previously recorded within theproject site boundaries.
Additionally, an archaeological survey was conducted for the project site. An intensive pedestrian survey was conducted on November 20, 2000, by EOAW staff archaeologists. An interval of no more than 15 meters was employed. Visibility was good to excellent. No cultural resources, including religious or sacred uses, were observed during the survey. Therefore, there isno potential Plum Canyon County Park Project Final Initial Study/Mitigated Negative Declaration 0/008PI.,. (""RlonNff</rr ((1",,/).""" O/l:JIO:/0':$ .HI

for impacts tocultural resources. No further archaeological work is recommended, and no mitigation measures are required. However, the following mitigation measure would minimize impacts to previously unidentified cultural resources if uncovered during project construction.
I
I
Mitigation Measure
M-V.l If previously unidentified cultural resources, including a potential feature or intact deposit, are exposed during ground disturbing construction activities, work shall be halted in that area, and the feature will need to be assessed for significance by a qualified archaeologist.

I
VI. GEOLOGY AND SOILS
Would the project:
I
a) Expose people or structures to potential substantial adverse effects, including the risk ofloss, injury, or death involving:
i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.
ii) Strong seismic ground shaking?
iii) Seismic-related ground failure, including liquefaction? iv) Landslides?
I
I Less Than Significant Impact. The project site is not located within the immediate vicinity of any major fault zones, including the most recent Alquist-Priolo Earthquake Fault Zone. The closest fault is the SanGabriel fault, which is located approximately 1.5miles southwestof the project site. Since earthquake-related hazards cannot be avoided in the Southern California region, the project site could be subjected to ground motion which could affect structures and/or park facilities. .The proposed park structures, such as the restroom/maintenance building, would be conducted in compliance with earthquake-resistant standards required by existing building codes (e.g.,Title 24 of the State Building Code). Habitable structures are not included in the proposed project, and all proposed structures would be constructed in compliance with uniform building codes. Therefore, the proposed project is not expected to increase the risk of exposure of people to impacts involvingfault rupture and seismic ground shaking.
I
I
I
I The California Department of Mines and Geology's Official Map of Seismic Hazard Zones for the Mint Canyon Quadrangle (which encompasses the project site) was released on March 25, 1999.2 Based on thereview of available USGS topographical maps, the project site is located within an area of liquefiable soils and earthquake-induced landslides. This could potentially affect areas on-site; however, prior to construction, existing building codes would be implemented to reduce the impact toa less thansignificant level. No mitigation measures are required.

The proposed project would not alter topography within theproject area. Minimal excavation would occur for the installation of the restroom/maintenance building.
Vegetation would be planted after construction; therefore, no significant erosion impacts are expected tooccur. No mitigation measures are required.I I
I
c) Be located on strata or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse?
I
.Less Than Significant Impact. No habitable structures would be developed as part of the proposed project; however, a small structure, a restroom/maintenance building, would be built in compliance with uniform building codes to ensure stable soils before construction. Therefore, no impacts from unstable soils are expected to occur. No mitigation measures arerequired.
I
d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code, creating substantial risks to life or property?
I
I
No Impact. The proposed project site consists of surficial soils, which are classified as non expansive soils. Therefore, there would be no impact due to expansive soils. No mitigation measures arerequired.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal ofwastewater? I No Impact. The proposed project would not involve the use of septic tanks to handle its wastewater generation. Therefore, no impacts are anticipated to result from project implementation. No mitigation measuresare required.

I
VII. HAZARDS
Would the project:
I
a) Create a significant hazard to the public or the environment through the routine transport, usc, or disposal of hazardous materials?
b) Create a significant hazard to the public or the environment through reasonably foreseeable upset· and accident conditions involving the release of hazardous materials into the environment?
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school?I I Less Than Significant Impact. The proposed project involves the construction of a public parkon a currently undeveloped open lot. There are small piles of debris across the site, which would be disposed of during the initial site clearing and grading phase of construction. The debris (primarily cementandmasonry rubble) and other excess materials at the site wouldnot pose a significant risk to the public as they would be hauled from the site and disposed of at a nearby landfill. As discussed below, no hazardous materials have been identified in the immediate vicinity of the site. Impacts regardinghazardous materials would not occur; therefore, no mitigation measures are required.

3.0 Discussion of Environmental Impacts and Mitigation Measures d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant . to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
No Impact. A review of the results of the hazardous materials/waste sites database search (performed to ASTM Standards) was conducted for the project site inNovember 2000.3 The results of the database search (provided in Appendix A) indicate that no hazardous material sites are known to occur within a one-mile radius of the project site. As such, no significant hazard to the public or the environment would be created as aresult of the project. No mitigation measures are required. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? 1) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area'? No Impact. The project site is located approximately ten miles northeast of Agua Dulce Airport, the nearest airport. Accordingly, the proposed project would not result in a safety hazard for people residing or working in the project area or visiting thepark. No mitigation measures are required. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
Less Than Significant Impact. The proposed project would not interfere with a current emergency response plan or an emergency evacuation plan for local, state or federal agencies. Access to all local roads would be maintained during construction. Any emergency procedures would be implemented within local, state, and federal guidelines during construction and operation of the proposed project. Therefore, no significant impacts are anticipated. No mitigation measures are required.
h) Expose people 'or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands?
Less Than Significant Impact. Implementation of the proposed project would not expose people or structures to fire hazard from flammable brush, grass or trees. Standard safety procedures and best management practices would be employed during construction, minimizing the potential risk for accidents to occur, including fires. Also, on-site landscaping would be maintained and watered regularly so as to reduce fire hazard impacts. The barbecue facilities in the group picnic area would be located over 50 feet fromthe nearest undeveloped area to the east. Accordingly, the siting of the proposed park facilities would not pose a long-term fire hazard. No mitigation measures are required.

3.0 Discussion of Environmental Impacts and Mitigation Measures VIII. HYDROLOGYANDWATERQUALITY
I Would the project:
I
I
a) Violate any water quality standards or waste discharge requirements? I
Less Than Significant Impact. The State Regional Water Quality Control Board (RWQCB) has adopted a General Construction Activity Storm WaterPermit for storm water discharges associated with any construction activity including clearing, grading, excavation reconstruction, and dredge and fill activities that"resultsin the disturbance of at least five acres of total land area. Construction of Plum Canyon County Park would disturb approximately seven acres of land area; therefore, a National Pollution Discharge Elimination System (NPDES) permit would be required for the project.
Compliance with the permit requirements would ensure that storm water runoff-related impacts would be less than significant; therefore, no mitigation measures arerequired.
I b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there should be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)?
I
I
I
Less Than Significant Impact. Construction of the tennis court, restroom/maintenance building, picnic shelter, walkways, basketball court, and parking lot would reduce the impervious surface area of the site by less than 0.25 acre. The remainder of the park would continue to allow subsurface infiltration through the grass lawns and landscaped areas. As such, the proposed project would not noticeably affect the local groundwater supply. No mitigation measures arerequired.
I
I
I
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site?
d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? I
I
Less Than Significant Impact: As discussed in Section 1.0, only minimal grading would be required toprepare the project site for construction. Existing drainagepatterns would be maintained, andrunoff from thepark wouldbe directed to the local storm drain network. Runoff from theproject site would drain to one of two storm drains along the eastern boundary of the site or to the curbside storm drains along Via Joyce Drive or Plum Canyon Road. Minor improvements on existing surface drainage structure may be required in the northeast corner of the Phase I area to avoid drainage problems at the proposed tennis court site; however, such issues would not be significant and would be resolved during the detailed design phase of the project. No erosion, siltation, or flooding on- or off-site isanticipated tooccur. Therefore, no significant impacts areexpected to occur; no mitigation measures are required.I

I 3.0 Discussion of Environmental Impacts and Mitigation Measures I e) Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems?
l) Otherwise substantially degrade water quality?I
I
I
Less Than Significant Impact. A storm water drainage system is currently in-place at the project site. There are two storm drains along the eastern portion of the site and several curb-side drains along Via Joyce Drive to the west and Plum Canyon Road to the south. Two manhole access points are also located in the Phase II area. Drainage from the park would be routed to the existing storm drain network.
I
The existing storm drain system would adequately accommodate the proposed park improvements.
The amount of surface water runoff would not substantially increase beyond existing levels, as most irrigation water and precipitation would infiltrate into the lawn's root system and underlying groundwater table. No mitigation measures ~rerequired.
I .g) Place housing within a lOO-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h) Place structures within a lOO-year flood hazard area which would impede or redirect flood flows?
i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? .
I
I
I
NoImpact. No housing is proposed for the project. In addition, theproject site is not located within an area designated as 1OO-yearor 500-year flood plain," Therefore, implementation of the proposed project would not subject people or structures to significant flooding impacts. No mitigation measures arerequired.
I
I
j) Inundation of seiche, tsunami, or mudflow?
I
No Impact. The project site is not located near a body of water; therefore, the potential for inundation by seiche, tsunami or mudflow is very low, if non-existent. Accordingly, implementation of the proposed project would not subject people or structures to inundation by seiche, tsunami, or mudflow. No mitigation measures are required.
IX. LAND USE AND PLANNING
I
I
Would the project:
a) Physically divide an established community?
I
NoImpaet. The construction of Plum Canyon Park would not divide the residential community or significantly impact low income or minority resources. The proposed project would develop approximately seven acres of an approximately 13-acre open lot. The lot is bordered by single family residences to the north, a scrub-covered hillside and utility corridor to the east, Plum Canyon Roadto thesouth,and residential streets tothewest. No mitigation measuresare required.

I
b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?
I
I
I
No Impact. The project site is located in an unincorporated area of Los Angeles County.
Development in this area is governed by local and regional plans including the CountyofLosAngeles GeneralPlanand theSantaClaritaValleyAreaPlan. The general plan land use designation for the site is Urban I, which allows for low-density residential development (1.1to 3.3 units per acre). The site is zoned as Residential Planned Development (RPD). This land use designation and zoning classification allows for public park uses, such as the proposed Plum Canyon Park. As such, the proposed would not conflict with general plan or zoning designations. No mitigation measures are required. -
c) Conflict with any applicable habitat conservation plan or natural communities conservation plan?
I
I
No Impact. The California Department of Fish and Game's Natural Community Conservation Planning (NCCP) program incorporates an broad-based ecosystem approach to planning for the protection and perpetuation of biological diversity. There are no active NCCP areas in the vicinity of the project site. The nearest such NCCP area is located on the Palos Verdes Peninsula nearly 50 miles south of the project site. Also, there are no HCP planning areas in the immediate vicinity of the project site. Therefore, the proposed project would not conflict with any habitat conservation plans or natural communitiesconservation plans. No mitigation measures are required.
I x. MINERAL RESOURCES
I
I
Would the project:
I
a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?
b) Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan I
Less Than Significant Impact. Development of the proposed project would involve the use of. construction materials, which include non-renewable resources. However, the construction of the proposed project would follow industry standards and would not use non-renewable resources in a wasteful and inefficient manner. Additionally, the proposed project would not result in the loss of availability of any mineral resource that would be of future value; therefore, there is no potential for significant impacts onmineralresources. No mitigation measures arerequired.
I XI. NOISE
I Would the project:
I
I
a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels?

I Short-term construction impactswould be mitigated to acceptable levelsby measures specified in the Los Angeles Noise Code, Section 12.08.440 (C)(D) and the mitigation measures identified below.
These measures would be enforced by the Los Angeles County Sheriff's Department in response to complaints only.
I
I
The project site is located in an area primarily consisting of single-family residences, which are located immediately to the north, west, south, and northeast of the project site. These sensitive land uses would potentially be exposed to noise generated from on-site construction activities. The distance from the boundary of the proposed construction activities to the closest single-family residences located adjacent to theproject site is less than 50 feettothenorth and west.

3.0 Discussion of Environmental Impacts and Mitigation Measures I
I
Construction noise levels at and near the project site during project construction would fluctuate depending on the particular type, number, and duration of use of various pieces of construction equipment. Table 4 shows noise levels associated with various types of construction-related machinery. According to this table, noise levels as high as 88 dBA would be experienced by adjacent sensitive receptors. In the event when all of the equipment is operating simultaneously throughout the construction phase of the proposed project, the noise levels at the closest residence would be even higher. Construction noise would be temporary and intermittent and would occur only during daytime hours, which is the least noise-sensitive time of the day. Construction noise would have a short-term significant impact. However, with the implementation of the following mitigation measures, noise impacts would be reduced to less than significant levels given the limited hours and short duration of theconstruction activities.
I
I MitigationMeasures
I
I
M-XI.l Project construction shall comply with tlie County .of Los Angeles Noise Code.
Construction activities shall be limited to the hours of 7:00a.m. to 8:00p.m. onMondays Fridays; prior written approval shall be obtained to conduct construction activities on Saturdays between the hours of 7:00 a.m. and 8:00p.m. No construction shall occur on Sundays and legal holidays.

I
I
I
I
I
M-XI.3 Temporary noise mufflers and noise attenuating devices, particularly along the northern boundary of theproject site adjacent 10the single-family residences, shall be employed to reduce noisegenerated during construction. (See Table4for anticipated noise reduction.) As discussed in Transportation/Circulation Section, no significant changes to traffic generation are anticipated to occur. Therefore, noise levels associated with traffic generation resulting from the operation of the proposed project is not expected to increase nor affect the ambient noise levels. No mitigation measures arerequired forpark operation.
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two milesof a public airport of public use airport, would the project expose peopleresidingor working-intheproject area to excessivenoiselevels? 1) For a project within the vicinityof a private airstrip, wouldthe project exposepeopleresiding orworkingintheproject area toexcessivenoiselevels?
I
No Impact. The project site is not located within an airport land use plan, within two miles of a public airport or public use airport, or within the vicinity of a private airstrip. The proposed project would not expose people residing or working in the project area or people visiting the project site to excessivenoise levels fromairports or airstrips. No mitigation measuresarerequired. l

3.0 Discussion of Environmental Impacts and Mitigation Measures XII. POPULATION AND HOUSING
I
I
I
Would the project:
a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
I
I
No Impact. The proposed project would not induce substantial growth to the area since it is a response to the existing need for recreational facilities within the current residential area. No growth-inducing impacts are anticipated to result from the proposed project. No mitigation measures area necessary.
b) Displace substantial numbers of existing housing, necessitating the construction of replacement 'housing elsewhere? .
c) Displace substantial numbers of people necessitating the construction of replacement housing elsewhere?
I
I
I
No Impact. The project site is currently vacant and, therefore, would not involve removal of any land uses, particularly residential uses, from the project site. No existing housing or residents would be displaced fromthe project site. Therefore, no population and housing impacts are anticipated, XII1. PUBLIC SERVICES
Would the project:
I
I
I
I
a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:
Fire protection?
I
I
I
Less Than Significant Impact. The County of Los Angeles Fire Department maintains its Division III Headquarters at 24875 N. San Fernando Road in Newhall, approximately six miles from the project site. This division handles two battalions and 15other stations; two of these other stations are located within approximately five miles of the project site.S Because the proposed local park is not anticipated to generate a significant fire hazard, the demand for fire protection services in the area is not expected to increase. The implementation of the project would be in accordance with the latest CountyFire Department codes and guidelines, including, but not limited to the following: _.,. • Specific fire and life safety requirements for the construction phase shall be addressed at the building fireplan check.
• Every building constructed shall be accessible to Fire Department apparatus by way of access roadways, with an all weather surface of not less than the prescribed width, unobstructed, clear- I

• Fire flows up to 5,000 gallons per minute (gpm) at 20 pounds per square inch (psi) residual pressure forup to a five-hour duration mayberequired. Final fire flowswill be based on the size of the buildings, their relationship with other structures, property lines, and types of construction used. Fire hydrant spacing shall be 300 feetand shall meet the followingrequirements:
I
I
No portion of lot frontage shall be more than 200 feet via vehicular access from a public fire hydrant.
No portion of a building shall exceed 400 feet via vehicular access from a properly spaced public fire hydrant.
I • Turning radii shall not be less than 42 feet. This measurement shall be determined at the centerline of the road. A Fire Department-approved turning area shall be provided for all driveways exceeding ISOfeet in length and at the end of all cul-de-sacs, All on-site driveways shall provide a minimum unobstructed width of 26 feet, clear-to-sky. The on-site driveway shall be within 150feetof allportions of the exterior walls of any building.I I Landscape design and construction would also use low-fuel volume and drought tolerant species.
Therefore implementation of the proposed project would not negatively impact the ability of the County of Los Angeles Fire Department to provide adequate service. No mitigation measures are necessary.
I
I
I
Police protection?
I
Less Than Significant Impact. The County of Los Angeles Sheriffs Department maintains 21 main stations throughout the County. The closest facility to the project site is the Santa Clarita Valley Station located at 23740Magic Mountain Parkway in Valencia, approximately 4.5 miles from the project site." Public safety and vandalism reduction is an important consideration in the development of the designof the facility. Construction areas would be secured throughout the course of construction as necessary to ensure the safety of the public. The proposed local park is not anticipated to generate a significant demand for police protection services in the area because of its size and purpose of use. No mitigation measures are necessary.

I
I
No Impact. The proposed project would not have any growth-inducing effects. Most of the visitors of the proposed local park would be from the adjacent residential and neighboring areas; therefore, no impacts on school enrollment are expected. No mitigation measures arenecessary.
Parks?
I
I·
I
No Impact. The proposed project would serve theresidents in the project area and is not anticipated to generate any additional population and, therefore, would not increase demand for neighborhood or regional parks or other recreational facilities. The proposed project would have a beneficial effect on parks and recreational opportunities by providing the community with a local park. No negative impacts toparks are anticipated, and no mitigation measures arenecessary.
Other public facilities?
I
I
No Impact. The proposed project is not expected to significantly affect any other public facilities in the area or in the community or County as a whole. No impacts are anticipated. No mitigation measures are necessary.
XIV. RECREATION
Would the project:
I
I
I
I
a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?
No Impact. The proposed project would not increase demand for neighborhood or regional parks.
Conversely, it would provide additional recreational opportunities by providing the community with a local park with a tennis court, children's play area, a multi-purpose field, and picnic areas. No negative impacts torecreation are anticipated. No mitigation measures arenecessary. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? I No Impact. According to the County's A Parks and Recreation Strategic Plan/or 2010, the Santa Clarita Valley Regional Planning Area, which includes the project site, would have a deficiency of 233.7 acres of local parkland.' The proposed project would involve development of a local park to increase recreational opportunities'in the community. This would slightly alleviate the deficiency in recreation facilities inthearea. No mitigation measures are necessary.I I

3.0 DiscussionofEnvironmentalImpactsand MitigationMeasures XV. TRANSPORTATION/CIRCULATION
I Would the project:
I
I
a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume-to-capacity ratio on roads, or congestion at intersections)? b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? I
Less Than Significant Impact. The project site is currently undeveloped and does not generate any vehicle trips. Accordingly, construction of the park would increase traffic on the surrounding residential streets and at local intersections. As described below, however, the increase inboth short and long-termtraffic levelswould beminor.
I Short-term construction impacts would be less than significant for this project. Construction workers would typically arrive at the project site in the morning and park their personal vehicles along Via Joyce Drive or on the project site. (Approximately 15 construction workers would arrive at and depart from the project site per day for the duration of Phase I and Phase II construction.) Construction equipment and supplies would be delivered to the project site at various stages of the construction process. No more than five delivery trips would be expected per day, largely because all heavy equipment would be staged on-site. Due to the limited number of vehicle and truck trips expected per day, construction activities would not alter normal traffic conditions around the project site.
I
I
I The proposed Plum Canyon County Park is a neighborhood park facility. As such, many of the park's visitors would arrive on foot or by alternative means of transportation (bicycle, etc.) from nearby residences. Some vehicular trips would be generated by the project, particularly during sporting events at the park, such as organized baseball or softball activities. Accordingly, the Institute of Transportation Engineers' (ITE) Trip Generation Manual (61h Edition) was used to determine trip generation rates for the proposed park facility. Conservative rates for "County Park" facilities were used todetermine maximum daily and peak hour trip estimates for the park, as shown inTable S.

3.0 Discussion of Environmental Impacts and Mitigation Measures I
Saturday is expected to be the busiest day at the park. As shown in the table below, approximately 16 vehicles would enter or exit the project site during the peak hour. On an average Saturday, approximately 86 vehicular trips would be expected over the course of the day. This incremental increase in traffic would not have a significant impact on local traffic intersections. Nearby intersections would continue to operate at acceptable levels of service during park operation as no significant increases in average delay times and volume-to capacityratios would be expected.
I
I
I
The proposed project would conform to the requirements of the County of Los Angeles Congestion Management Plan (CMP). The CMP requires that traffic studies be prepared to document impacts to all CMP monitoring intersections where the proposed project would add SOor more peak hour trips.
Because theproject would generate fewer than SOpeak hour trips and there are no CMP intersections inthe vicinity ofthe site, impacts to CMP monitori~g stations arenot anticipated.
As described above, impacts to the local street system would be less than significant; therefore, no mitigation measures are required.
I
I c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? I No Impact. The proposed project would not generate air traffic nor affect such activities. No mitigation measures are required.

"I
d) Substantially increase hazards to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. The proposed project and the parking lot would meet all applicable design and safety requirements; therefore, no hazards associated with a design feature would occur. No mitigation measuresare required.
e) Result in inadequate emergency access?
I No Impact. No changes in access to emergency facilities or nearby land uses are expected to occur as aresult of implementation of theproject, No mitigation measures arerequired.
I 1) Result in inadequate parking capacity?
I
Less Than Significant Impact. A total of 15parking spaces would be provided under eachphase of park construction (for a total of 30 parking spaces at project buildout). As shown in Table 5, peak hour trip generation would not exceed the available parking supply. In the event that additional parking is needed, street parking would be available along Via Joyce Drive. Impacts related to parking supplywould be less'thansignificant; therefore, no mitigation measures are required.
I
I
~
g) Conflict with adopted policies supporting alternative transportation (e.g., bus turnouts, bicycle racks)?
No Impact. The proposed project would not conflict with adopted policies supporting alternative transportation.

a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board?
b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?
I
Less Than Significant Impact, The proposed project isnot anticipated togenerate a significant amount ofwastewater as the only use on-site that would generate wastewaterwould be therestroom building. Similarly, water usage would also be minimal. No new wastewaterand water systems would be required. Therefore, impacts towastewater treatment andwatertreatment would be less than significant.

Major portions of the project site wouldremain impervious; a limitednumber ofproject components would require paving or impervioussurfaces, such asthe tennis court,thebasketball court, the parking lots, and walkways. Thedevelopment of theproposed project isnot anticipated to significantly changethe amount of impervioussurfaces on-site to increase surface water runoff. Therefore, this would be a less than significantimpact. No mitigation measures arenecessary.

I Less Than Significant Impact. The proposed project is not anticipated to use a significant amount of water as the only uses on-site that would use water would be therestroombuilding and landscaped areas and the multi-purpose field, which would both require irrigation. Similarly, wastewater generation would also be minimal as the only use on-site that would generate wastewater would be the restroombuilding. No new wastewater and water systems wouldbe required. Therefore, impacts to wastewater treatment and water treatment would be less than significant. No mitigation measures are necessary.

3.0 Discussion of Environmental Impacts and Mitigation Measures Less Than Significant Impact. The proposed project would not require new solid waste facilities.
Construction debris would be recycled or transported to the nearest landfill sites and disposed of appropriately. The nearest landfill is the Chiquita Canyon Landfill located at 29201 Henry Mayo Drive in Castaic, approximately 15miles from the project site; other landfills sites within 30 miles of the project site are Bradley West Landfill (approximately 2S miles away), Sunshine Canyon Landfill (approximately 26 miles away), and Antelope Valley Landfill (approximately 30 miles away)." The amount of debris generated during project construction and operation is not expected to significantly impact landfill capacities; solid waste generation by the new local park would be minimal. The proposed project would comply with applicable regulations related to solid waste Operation of the proposed project would be subject to the requirements set forth in the County's Solid Waste Management Program. Although no significant impacts to solid waste facilities are anticipated, the following measures would further ensure solid waste minimization during project construction and operation.
Mitigation Measures
M-XVI.l Prior to completion of plans and specifications, the County of Los Angeles Department of Parks and Recreation shall include in thefinal plans and specifications the requirementfor the construction COiltractor to work with the County ofLos Angeles Department ofParks and Recreation's recycling coordinator, Mr. Boyd Horan, to ensure that source reduction techniques, procurement of recycled building materials, and tile development of recycling programs during construction and operation of thefacility are considered and implemented whenever possible. The County of Los Angeles Department of Parks and Recreation's recycling coordinator shall review the plans and specifications for incorporation of the" 'I ~ specified language. The County of Los Angeles Department ofParks and Recreation shall demonstrate tothesatisfaction of the County ofLos Angeles Department of Public Worksthe incorporation ofthis requirement.
M-XVI.2 Prior to completion of plans and specifications, the County of Los Angeles Department of Parks and Recreation shall clearly identify bin enclosures and recycling containers, in accordance with the California Solid Waste Reuse and Recycle Access Act of 1991, as amended. The County of Los Angeles Department of Parks and Recreation shall demonstrate to thesatisfaction of the County ofLos Angeles Department of Public works the incorporation ofthis requirement. '
XVII. MANDATORY FINDINGS OF SIGNIFICANCE
a) Does the project have the potential to degrade 'the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
Less Than Significant Impact. The analysis conducted in this Initial StudylMitigated Negative Declaration results ina determination that the project, either individually or cumulatively, would not have a significant effect on the local environment. The project site hasbeen previously disturbed and is devoid of fish or significant wildlife, andlor plant populations.

B-1 The project site will be annexed into District No. 26 to receive sewerage service. Ms.
Margarita Cabrera, Engineering Technician for the Planning and Property Management Section of the County Sanitation Districts of Los Angeles County, was contacted regarding annexation of the site into District No. 26. According to Ms. Cabrera, based on an estimated park area of 12.92 acres, the annexation processing fees total - approximately $7,378; this application for sewer connection will be processed after an approved annexation application, which would include a copy of this CEQA document (after certification), is submitted to the Local Agency Formation Commission I
I B-2 The proposed project will discharge to a local sewer line for conveyance to the Districts' Bouquet Canyon Relief Trunk Sewer, which is located approximately eight miles southwest of theproject site.I
I
I
B-3 The two water reclamation plans providing wastewater treatment in the Santa Clarita Valley are not anticipated to be impacted by the proposed project since the proposed project is expected to generate an average wastewater flow of 1,357gallons per day. In 2002, the Santa Clarita Valley Joint Sewerage System (SCVJSS) will have an expanded treatment capacity of 28.1 million gallons per day (mgd). Currently, SCVJSS processes an average flow of 16.6 mgd. The project addition of 0.0014 mgd would be a small fraction of the treatment capacity that it is expected to have a less than significant impact on the two water reclamation plans inthe area.
I B-4 The County will be subject to pay any applicable utility connection fees to the appropriate service providers.
I
I
B-5 The proposed project has been identified and included in the County's A Parks and Recreation Strategic Plan for 2010, which was prepared in 1992 consistent with the Conservation and Open Space Element of the 1980 County General Plan. Therefore, it may be assumed that the regional growth forecast adopted by the Southern California Association of Governments includes the proposed project. Accordingly, it may be assumed the proposed project would generate wastewater flow within the level that is legally permitted toconform with the requirements of theFederal Clean Air Act.

The following County Fire Department codes and guidelines have been added to the Fire Protection discussion on page 3-17 of the Draft Initial Study/Mitigated Negative Declaration:
• Specific fire and life safety requirements for the construction phase shall be addressed at thebuilding fireplan check.
.. ~
• Every building constructed shall be accessible to Fire Department apparatus by way of access roadways, with an all weather surface of not less than the prescribed width, unobstructed, clear-to-sky. The roadway shall be extended to within 150feet of all portions of the exterior walls when measured by an unobstructed route around the exterior of thebuilding.
• The maximum allowable grade shall not exceed 15 percent, except where the topography makes it impractical to keep within such grade, and then an absolute maximum of20 percent shall be allowed for up to 150feet in distance. The average maximumallowed grade, including topography difficulties, shall be no morethan 17 percent. Gradebreaks shall not exceed 10percent in 10feet. • Fire flows up to 5,000 gallons per minute (gpm) at 20 pounds per square inch (psi) residual pressure for up to a five-hour duration may be required. Final fire flowswill be based on the size of the buildings, their relationship with other structures, property lines,and types of construction used. Fire hydrant spacing shallbe 300 feet and shall meetthe followingrequirements:
No portion of lot frontage shall be more than 200 feet via vehicular access from a public firehydrant.
No portion of a building shall exceed 400 feet via vehicular access from a properly spacedpublic firehydrant.
• Turning radiishall not be lessthan 42 feet. This measurement shall be determined at the centerline of the road. A Fire Department-approved turning area shall be provided forall driveways exceeding 150 feet in length and at the end of all cul-de sacs.

Response toComments fromthe State of California
Department ofFish and Game
Scott Harris, Associate Wildlife Biologist
Response
During preparation of this Final Initial Study/Mitigated Negative Declaration, consultations with the California Department of Fish and Game (CDFG) were conducted to address CDFG's comments andconcerns regarding theproposedproject. Specifically, adverse impacts to the higher quality coastal sage scrub, which could potentially support the federally listed threatened California gnatcatcher, were discussed with CDFG.
According to Mr. Scott Harris, Associate Wildlife Biologist with CDFG, since the site is rather degraded, construction impacts on the California gnatcatcher would not be significant if grading activities were to occur outside of the breeding season, which generally runs as early as February 1 through August 31 (pers. comm. March 2001).
However, based on similar consultations with the U.S. Fish and Wildlife Service (USFWS), focused California gnatcatcher surveys were reconunended; the County has recently completed such surveys. No California gnatcatchers wereobserved on site or in the surrounding areas during the focused surveys.
The County is proposing to initiate construction in November, during the non-breeding season. Both the CDFG (Mr. Scott Harris) and USFWS (Mr. Rick Farris [Senior Ecologist] and Ms. Louise Lampara [Fish and Wildlife Biologist]) have concurred that avoidance of the breeding season would suffice for compliance with the Migratory Bird Treaty Act. Mitigation measures have been added to the ISIMND in the event that construction occurs during the breeding season.
Construction activities (including vegetation disturbance and removal) will be initiated during the non-breeding season (September 1 through February 28). All required vegetation disturbance will occur during the non-breeding season.
If construction activities are required during the breeding season (March I through August 31), all vegetation on site and within a 300-foot buffer surrounding the site will be monitored bya qualified biologist. If any nesting activity is detected withinthe site or 300-foot buffer, all construction will cease within 300 feet of the active nest until all breeding/nesting activity has been completed at that location.
In response to CDFG concerns, an additional site survey was conducted on April 4, 2001. The results of this spring faunal survey have been incorporated into the ISIMND.
No sensitive animal species were observed or detected on,oradjacent to, the site.

Response
Ms. Betty Courtney of CDFG was contacted regarding impacts to on-site drainages.
Based on Ms. Courtney's visit to the project site on March 30, 2001, these drainages were determined to be under CDFG jurisdiction. Therefore, because these drainages would be altered as a result of the proposed project, a Streambed Alteration Agreement would be required to complywith Section 1601of the Fish and Game Code.
The County of Los Angeles Department of Parks and Recreation will submit to CDFG a notification package upon certification of this Final ISIMND. The notification package will include identification of project impacts to on-site drainages and will provide mitigation, monitoring, and reporting commitments for issuance of the Streambed Alteration Agreement. According to Ms. Courtney, the proposed project would have a minor impact on the on-site drainages under CDFG jurisdiction. However, because of CDFG's no net loss policy, impacts to the two on-site drainages would need to be mitigated. As indicated by CDFG, a 1.5:1 mitigationratio would be required for the proposed project. Mitigation acreage would need to account for 0.069 acre of plantings.
A mitigation measure has been incorporated into the ISIMND to address impacts to the CDFGjurisdictional areas.
The County has no plans to develop the remaining portion (approximately six acres) of theproject site at this time. However, the County wishes to havethe option ofbeingable to develop the remainder of the site for future park expansion. Any development plans proposed for the remaining six acres would be subject to future environmental analysis and CEQA documentation. ,

It is likely that the Plum Canyon Park and neighboring community will be annexed into the City in the future, and therefore, the City would then assume responsibility for the maintenance of Plum CanyonPark.
Duringthe programming ofthe Plum Canyon Park, the possibilityforadditional parking may become necessary. The softball field, during a normal T·ball season, wouldrequire parking for a minimum of40 cars (20 spaces for those players onthe field.and an additional 20spaces forthose arriving fer tho next game). In addition. the remainder of the site would require parking for the tennis court,basketball court,group picnic area. horseshoe pit. and the tot-lot playarea allofwhichwillbeutilizedduring the same time periodas the softball program.

F-l The County concurs that it is likely that Plum Canyon County Park will be annexed into the City of Santa Clarita in the future. At that time, the City would assume the responsibility of park maintenance; however, the County will assume responsibility for park maintenance until that time.
I F-2 The proposed project would provide a total of 30 parking spaces. If parking demand exceeds on-site parking capacity during peak periods of use, the excess parking demand would be easily satisfied by.on-street parking on Via Joyce Drive for short-termneeds.
I F-3 The designs of the restroom and athletic field facilities arenot environmental issues and, therefore, do not pertain to the CEQA process. The City's comments regarding these park design issues have been forwarded to the Department's Project Management Division for consideration.I

Response to Comments from the State of California
Governor's Office ofPlanning and Research, State Clearinghouse Terry Roberts, SeniorPlanner
Response
The State Clearinghouse received comments from the State of California Department of . Transportation (Caltrans) after the end of the state review period, which closed onMarch 14,2001. However, these comments are still considered and have been incorporated in this document.
Caltrans has no comments on the project at this time. Caltrans' recommendation that construction-related truck trips on State freeways and highways be limited to off-peak commute periods along congested corridors has 'been considered. As stated in Section XV, Transportation/Circulation, no more than five delivery trips would be expected per day, largely because all heavy equipment would be staged on-site. Due to the limited number of vehicle and truck trips expected per day, construction activities would not alter normal traffic conditions around theproject site.

Department of Public Works, Watershed Management Division Rod H.Kobomoto, Assistant Deputy Director
Response
According to the County of Los Angeles Department of Public Works (DPW), it has no comments on the Draft ISIMND at this time. However, in the event that the proposed project would result in the connection to or modification of any of PPW's drainage facilities or increase the flow into the storm drain system, the proposed project would obtain anyrequired permits from DPW.
Underground storage tanks,(USTs) and industrial waste control or disposal facilities are not currently present on the project site. The proposed project would not involve construction/installation, modification, orremoval ofUSTs or industrial waste control or disposal facilities.
As discussed in Section Vlll, Hydrology and Water Quality, construction of Plum Canyon County Park would disturb approximately seven acres of land area; therefore, a National Pollution Discharge Elimination System (NPDES) permit would be required for the project. Compliance with the permit requirements would ensure that storm water . runoff-related impacts would be less than significant; therefore, no mitigation measures are required. Permit requirements include obtaining Standard Urban ..Stormwater Mitigation Plan (SUSMP) approval and implementation of Best Management Practices (BMPs) during project construction and operation.
The County will submit a drainage concept to DPW for review and approval prior to approval of the proposed project and certification of the Final ISIMND. As part of the NPDES permit, permanent post-construction Best Management Practices (BMPs)would be incorporated into theproject design tominimize impacts to water quality.
As stated by DPW, the proposed project would comply with all applicable ordinances and codes; therefore, it would not have significant environmental effects froma geology and soils standpoint,

6.0 Comments Received on the Draft Initial Study/Mitigated Negative Declaration and Responses Response to Comments from the California Regional Water Quality Control Board LOS AngelesRegion,TMDL Unit
Elizabeth Erickson,Associate Geologist
Response
This comment letter was received after the close of the public comment period, which ended on March 14,2001; however, the County of Los Angeles Department ofParks and Recreation appreciates the comments provided by the Los Angeles Regional Water Quality Control Board (RWQCB). The RWQCB's comments have been reviewed, and the issues discussed are best addressed during the preparation of the permits and plans required for the proposed project, including the National Pollution Discharge Elimination System (NPDES) permit, the Stormwater.Pollution Prevention Plan (SWPPP), and the Standard Urban Stormwater Mitigation Plan'(SUSWMP), which will identify measures and best management practices (BMPs) to reduce impacts to groundwater and water quality. With the implementation of the above plans and BMPs, theproposed project would not impair downstream reaches of the Santa Clara watershed.
The proposed project would contribute little, if any, nutrients, salts, coliform bacteria, andpesticides tothe watershed.
To comply with and implement the NPDES permit, specific BMPs would be required by the County and various regulatory entities. The SWPPP and the SUSWMP, which would be required for the project, would also specify the BMPs to be implemented.
Examples of some general BMPs that would be anticipated for.the project include the following:
Construction
• Scheduleexcavation and grading work for dry weather.
• Use as littlewater as possible for dust control.
• Never hosedown dirty pavement or impermeable surfaces where fluids have spilled; sweep up dry spilled materials immediately; clean up spills on dirt areas by digging up and properly disposing of contaminated soil, and report significant spills to the appropriate spill response agencies immediately.
• Maintain all vehicles and heavy equipment; frequently inspect for leaks. Conduct all vehicle/equipment maintenance and refueling at one location, away from storm drains; perform major maintenance, repair jobs, and vehicle/equipment washing off site;.use drip pans or drop cloths to catch drips and spills, if draining and replacing motor oil, radiator coolant, or other fluids on site; and do not use diesel oil to lubricateequipment or parts.
• Keep construction materials out of the rain. Store both dry and wet materials under cover,protected fromrainfall and runoff. Also protect drymaterials fromthewind.

Response
Construction (Continued)
• Secure open bags of cement to keep windblown cement powder away from streets, gutters, storm drains, rainfall and runoff.
• Apply concrete, asphalt, and seal coat during dry weather to prevent contaminants fromcontactng stormwater runoff. .
• Utilize revegetation, if feasible, for erosion control after clearing, grading, or excavating.
• Cover stockpiles and excavated soil with secured tarpsorplastic sheeting. • Remove existing vegetation only when absolutely necessary; consider planting temporary vegetation for erosion control on slopes or where construction is not immediatelyplanned, and plant permanent vegetation as soonas possible.
Operation
• Do not overwater landscaping. Conserve water by using irrigation practices such as drip irrigation, soaker hoses or micro-spray systems.
• Donot blow orrake leaves into the street, gutter, orstormdrains. • Use plant vegetation that is native, non-invasive, drought tolerant, and pest tolerant to minimize chemical and labor use over the shortllong-term; minimum use of pesticides and/or fertilizers would reduce the potential for chemical/nutrient runoff or groundpermeation toaffect the water quality inthearea. • Use organic ornon-toxic fertilizers.
• Do not over-fertilize and donot fertilize near ditches, streamsor other waterbodies. • Storepesticides, fertilizers and other chemicals inacoveredarea to prevent runoff.
The proposed project would involve the development of a local park, which would consist of site utilities and infrastructure, off-street parking, walkways, children's play area, tots play area, restroom building and maintenance area, group picnic shelter, basketball court, tennis court, multi-purpose athletic field. Some of these uses would create new impervious surfaces. As stated on page 3-12 of the Draft ISIMND, the impervious area of the project site would be less than 0.25 acre after project Plum Canyon County Park Project Final Initial Study/Mitigated Negative Declaration fJ/(J()3 Plu", ('''',,,,.

development; currently, the site is unpaved, undeveloped, and consists entirely of pervious surface. The remainder of the park would continue to allow subsurface infiltration through the grass lawns and landscaped areas. Therefore, the proposed project is not anticipated to significantly change the amount of surface water runoff, percolation, and groundwater beneath the project site.
The County will coordinate with the RWQCB during the permitting and final design process.

SECTION 7.0 MITIGATION MONITORING
ANDREPORTING PROGRAM
I
Public Resources Code, Section 21081.6 (Assembly Bill 3180) requires that mitigation measures identified in environmental review documents prepared in accordance with CEQA are implementedafter a project is approved. Therefore, this Mitigation Monitoring and Reporting Program (MMRP) has been prepared to ensure compliance with the adopted mitigation measures during the final plans and specifications.construction, and operation of thePlum Canyon County Park Project.
I
I
The Los Angeles County Department of Parks and Recreation is the agency responsible for implementation of the six mitigation measures identified in the ISIMND. This MMRP provides the Los Angeles County Department of Parks and Recreation with a convenient mechanism for quickly reviewing all the mitigation measures including the ability to focus on select information such as timing and implementation phase. The MMRP includes the following information:
I
I
• the phase of theproject during which adoption of the mitigation measure should be implemented • the phase of the project during which the implementation of the mitigation measure should be monitored;
I
I
• the enforcement agency; and,
• the monitoring agency.
I
I
I
I
The MMRP also includes a checklist to be used during the mitigation monitoring period. The checklist will verify the name of the monitor, the date of the monitoring activity, and any related remarks for each mitigation measure.

Subject: ResultsofFocusedCoastalCalifornia Gnatcatcher Surveys Conducted at the Plum Canyon Park Site,LosAngeles County
Dear Mr.Farris:
This report is notification that focused presence/absence surveys for the coastal Californiagnatcatcher (Polioplila califomicacalifomica)have beenconducted forthe Plum Canyon County Parkprojectsite,LosAngelesCounty, California (Appendix A, Figure 1). The project is not a participant in the Natural Community Conservation Planning (NCCP)program. These surveys were conducted by Erik LaCoste ofEDAW,Inc.(formallyKEAEnvironmental, Inc.) pursuant to the terms and conditions ofpermit numberTE-027736-1,issued under Section10(a)1(A)ofthe Endangered SpeciesAct,asamended. '
ThePlum Canyon County Parkprojectincludes theconversion ofapproximately 7 of13acres ofundeveloped land into apassive and active year-round public park.
Developed areas would consistofwalkways, utilities, totsplay area,siteamenities (picnic tables, park benches, bicycle rack, etc.), landscape and irrigation, restrooms/maintenance area,a1S-spa'ceparking lot,security lighting,and signage.
The primary objective of the project, as identified by the Los Angeles County Department ofParks and Recreation,istodevelop anew park that would provide passive and activeyear-round recreation opportunities toserve thelocalresidential community. Specifically, the project objective is to provide a localpark with a service radius of up to one-half mile. Mitigation measures to off-set impacts associated with this project include focused surveys for the federally listed threatened coastal California gnatcatcher toensure that impacts tothisspecies are avoided.
METHODS
The gnatcatcher survey area included all appropriate gnatcatcher habitat in the projectimpactarea aswellasallappropriate habitatwithin a500-footbufferaround the impact area (Appendix A, Figure 2). A total of approximately 13.0acres of appropriate habitat were included in the survey area. Surveys were conducted following the Coastal California Gnatcatcher Presence/absence Survey Protocol (USFWS 1997). Taped gnatcatcher vocalizations were occasionally played throughout thesurveys. Accordingtothesurvey protocol,allareasnot included in the NCCP program should be surveyed a minimum of 6 times when conducted between March 15and June30.Focused surveys were conducted between May 14 f)l'!r.IIlN, PLMHIIHO ANO ~N\llnO"''''I!IITS WORLOWIOE

fourth. The area in general is very active with human activity, particularly development. Approximately half of the site has been disturbed in the past by grading and terracing, possibly during initial housing development in the immediate area. Vegetation in this disturbed area is consistent with disturbed coastal sage scrub habitat: vegetation consists of an almost monotypic stand of deerweed (Lotus scoparius)with fewforb(non-grass herbaceous cover)species.A drainage occurs in the northeast comer of the site. This drainage has few plant speciesand, along with the terraced area, appears tobe used frequently asan off road recreational area by localkids.
Coastal sage scrub habitat, a vegetation type preferred by the coastal California gnatcatcher, does cover the eastern half of the site adjacent to both the disturbed area and the drainage. Dominant plant species include purple sage (Salvia JeucophyUa),California sage (Artemisia caJifomica), and California buckwheat (Eriogonum /ascicuJatum).Mostofthecoastalsagescrub occurs outside theproject boundary yet within the500-footbuffer area.
No coastal California gnatcatchers were observed or detected during any of the focused surveys. The absenceofthegnatcatcher may be attributed totheisolated nature of theproject site and thehigh levelof urban development. Inaddition, the CaliforniaNatural DiversityDatabase(CNDDB)doesnotcontainanyrecordsforthe gnatcatcher inthisarea.Wildlifespeciesobserved during thesurveys isincluded in Appendix Band field forms areincluded in Appendix C.

MEMORANDUM
TO Lillie Lowery, Departmental Facilities Planner I
FROM Madonna Marcelo
DATE November 2,2001
CC
SUBJECT USFWS Concurrence with the Results of the Gnatcatcher Surveys EDAW contacted Mr. Rick Farris of the U.S. Fish and Wildlife Service (USFWS) on October 24, 2001: to confirm the adequacy of the report we submitted to the USFWS in July presenting the results of the coastal California gnatcatcher surveys we conducted for the Plum Canyon County Park project site.
Mr. Farris verbally confirmed thatour report was satisfactory to the USFWS. Subsequently, on November I, 2001, Mr. Farris stated in an e-mail that "the coastal California gnatcatcher survey report sent to us inJuly appears to be adequate. Because none were sighted, no further coordination with us is required at this time. However, if the species appears during the project, activities must cease until we are contacted and the appropriate coordination is completed; possibly including application for an incidental take permit."
