Thank you for providing RegioLai Beard staff the oppomtnity to comment on the project documentation. We have the following comments regarding the proposed pvject, LOCATION AND DESCRIPTION OF PROJECT Placcr county is proposing to update the current 1975 Mattis Valley Community Plan (Community Plan) to addross new environmental and land use issues in the ttron as wall. es bring die utilonal Plan into consistency with the 1994 Placcr County General Plan. The protect area encompassed by the Comiriunity Plait consist.4 of approximately 35 square miles of Jai area generally bounded by the Placer/Navada County litre to the north,Highway A9 to tide west, the Luce Tahoe Basin boundary to the south and the California/Neva in state line to the east. CONMIENTs 1. The Regional Boa_d Is a responsible agency pursuant to the California Environmental Quality Act(CEQA) for this proposed project. Water quality control standards for the Truckee River Hydrologic Unit contained in the Water Quality Control Plant for the Lahowan Region (Basta Plan) are applicable to WS project, The Regional Board hss i•dentifred significant water quality:slues with the Truckee River,Maras Creek, and their tributaries. Specifically, water quality thrcatened to be exceeded for ch:0.1des and phosphorus. In addition,the Truckee River is listed on the Clean Waver Act Section 303!d) List as an "impaired water body"due to high sediment levels.

' 4 Several of the new developments proposed w7thin the Community Plan wti: include new golf courses. The Coniraunity Plan should include conditions on tna piaaatng, development and operation of epproved golf courses that bush and regulate the use of chemicals, including fertilizers,pesticides,and other economic poisons. Additional guidelines in the Community Plan should specify criteria w minimize the acreage of the playing areas retptiring chemical use. Both Placer County and the Regional Board new require the rlevelopinent of chemical application management plans (C>'iAMPs)for new golf courses. Enforcesbie guidelines for the development of CHAMPS that minimize chemical use should be included in the Community Plan. Taldna these adidelines into account,the EM should address impacts of the cumulative development and uperation of all new golf courses approved w+thin the Community Plan,is Conjunction with those drat have already been developed,to demonstrate that aA wirer quality standards contained in the Basin Plan can be met. i. New residential and commercial development will increase the use of fertilizers, pesticides, and other economic poisons within the project area. Unlike large golf courses with CHAAiPs, chemical use by individuals and commercial establishmems cannot be easily regulated or controlled. The EIR should address impacts from the cumulative development and if such usage is ahou.n to adversely affect ground or surface water quality, the EIR and the Community Plan should include effective controls to litnit such usage, or proposed m)tigition measures that will ensure compliance with x2ter quality standards California EnvirenmsraW Pralection Ageney 'Tine anexV raaaemee ratinr cab(crosa is tee.

The M should consider whether additional buffer zones are appropriate and ncoassary to protact wetlands,surface waters and 100-year flood plains of Ntartis Crwk, the Truckee River, and their tributaries,and-to ensure compliance with other water quality standards Wetlands will be impacted not only from individu,! developments but also from the utilities and road infrastructure neces9t y to serve these developments. The Community Plan should specifically address altemative construction practices Otaizcd in consttucti4e underground utility lines,such as boring, in order to avoid impacts to wetlands and other surface waters, R.

If access to wetlands is unavoidable, the cra$muniryplan should address eonstrueuoit of alternate walkways that can avoid impact to wetlands. The Community Plan or EIR should also address how such walkways/access will ensutte compliance with water qualit%/ standards, 9 We presume the Community Plan will require severing of most areas where development wilt be permitted and that no on-site septio.$)5tems will be allowed.

This letter is to supplement our earlier comments. As noted in our earlier comments,the MND does not indicate the source of the Water to be used to supply the proposed project and does not indicate the environmental effects of develuping that supply. It may be that the District plans to rely on ground water in the Martis Valley Gtouud Water Basin. MAPF and $let Wfttch are cnnrerned that tilt,, snfc yield of the Martis Valley Ground Water Basin has not been adequately studied, and thus, the availability of ground water for the proposed project and other projects intending to rely on Around water has not been established. These concerns are borne out by the attached anatvsis of the Ground WarerAvailabilily in the Jklarris Valley Ground 11ater,Basin report prepared by Nimbus Engineers (March 2001) ("Basin Study"),prepared by Acton, •AME") h dro eologss consulted by MAPF andMtckals n Environmental, Inc ( SierraWatch. uQ:rrStut ls:sJ 2s SHCTEORKA1.1' �1t;1;1:nna 'tlennbers of the Board September 5,2001 Page 2 The analysis provided by XIVIE is summarized by the follu"virug poims- The Basin Study assumes that all ground water flowing into the Truckee lave„ Prosser Creek Reservoir, and Prosser Creek is available far extraction to supply growing water needs in Truckee and the surrounding region. The Basm Study provides no analysts of the environmental consequences of stopping all ground water discharge to the Truckee River,Prosser Creek Reservoir,aid Prosser Creek.. The Basin Studymakes numerous assurptons regwduug rechdrgc efficiencies and Basin conditions that have the likely effect of overstating the amount of groundwater available for extraction. The assumptions in the Basra Study are not sufficiently supported by explanation or in mmarion available in peer-reviewed literature. The assumptions operate to overstate the amount of ground wate7 available for extraction,but the assumptions 4iouid be const nvative since groundwater from the ivlartis Valley Ground Water Basin will be the principal supply of water for growth in the uegiui(see Master Plan at 5-9)and since a sig,lificant amount of additiorwl ground water estrac+ion from the Basin Is planned already for the District's system improvements (see Master Plan at 5-9). A calibrated numerical model should be developed for the Martis Valley Ground Water Basin. Such a model would tnore reliable than the water budget approach employed by Nimbus Engineers. In adelidtm to developing an informative model of the safe yield of the biro tib Valley Ground Water Basin,the District must analyze the environmental consequences of extracting iatge amounts of ground water iiom the Basin be*are committing to withdraw water for the proposed project or other system improvements.

This letter provides out coromcnt5 on the review of the document. Two approaches to estimating safe yields from �raund water basins are the use of a hydroloc ice! budget model and tho use or a calibrated numerical model. The use of the hydrologic budget approach to estimate safe yields ham a basin, as was done in the Basin Study, is "fraught w Mi problems" (Frieze and Cherry, 1979 Ipugc 2071), As discussed in the ensuing colnutanis, thane is much uncertainty in many of tiro budget inputs,and in this ease, the budget inputs seem to rely considcrably upon the judgment of personnel at Nimbus Engineers (Nimbus) rather than on objective dsm or inromiminn acaliable In published literature.

Under the Icast favorable conditions, a recharge efficiency of 15 percent wa.i used (Table 1), and over the entire Basin, a recharge ci7ieiency of 25.3 percent iwas used (Table 2). A Basin-wide reehargo otiicienoy of 25.3 percent is greater than the 11 percatt value referenced in literature (Borger, 2000).

Nimbus then used this value as part (if the ground water that is available for extraction (Table 12). The greater Truckee River ground water discharge value was calculated by balanchig inputs and nutputs. As discussed above, the inputs may be anifleially inflated by precipitation recharge values, and possibly by the ground water transfers into the ELmin.

Description of Project: (Describe the whole action involved, including but not limited to later phases of the project, and any secondary,supp rt,or off-site features}teeessary for its implementation.) The proposed project involves the construction of two new wa.er.storage tanks,access road, and underground utilities including pipelires, electrical conduits a Id communication conduits. The storage tanks will provide approximately 4,OOD 000 gallons of storage lin two tanks. The first tank will be q: 1,500,000 gallons and the second tank 4,500,000 gallons.This project is expected to lake place ill two phases. The first phase will involve all lofthe site work, the pipeline and conduits, the access road,and cu,ts[tuctiun of the first tank. The second phase, expected to be completed in 3 to 5 years,will consist of r the construction of the second tank. The first tank is expected to be approxii�Irttately 90.5 feet in diar>teter by 32 feet high constructed of welded steel. The second tank will be approximately 116,0 feet in diameter by 32 feet high also constructed of welded steel. Construction will also intlolve grading a level li jd for the tanks and nccea.a around the tanks,construction of a retaining wall,and grading of a cut slope on the uphill side ofthe tanks. The I f !k I r i I Sauers Ensineerins Inc. 5302656834 P. 05 i access road will involve approximatol}� 1,200 feet of new road construction. The underground utilities will involve construction of approximately 1,200 feet of pipellne and conduits. The proposed Bridge Street 6160 Wal i Stn*age Tank project Is included in and consistent with the District's"Truckee Water System Wat r Master Plan Update"along with the Environmental initial Study and Negative Declaration adopted in 201. The master plan was in turn based on the General Plan of the Town of Trucker. This project,along with all of the pwjm;ts n the Water System Master Plan Update arc intended tv provide water service for itje growth and developTent described in the general plan. `l he Town of Truckee General Plan was approved and the General(Plan pleat klR certified in 1996. ti Construction of the tanks,paved accessI around the tanks, and access road will result in approximately 1.1 acres of new impervious surface. The uroject will result in a tptal of approximately 2.1 acres of ground disturbance. 1I CFQA Tieirm2 Process The California Environmental Quality ct(CirQA)encourage lead agencies to utilize,pievivus environmental analyses when a propostd project is related to an earlier project that was subject to CEQA analysis. Tiering is used on site-specitic projects to avoid repetitive discussions of issues previously analyzed as part of a broader project E G'EQA Guidelines�ection 15152 includes the following: i "(a)`Tiering' refers to using the an lysis of general matters contained in a broader EIR(such as one prepared for a general plan or polic statement)with later EIRs and negative declarations on narrower projects; incorporn... by rafere is the general discussions from the broader EIR; and concentrating y the later EIR or negative decisratioi solely on the issues ecif c to the later project." "(b)Agencies arc encouraged to tic' the environmental analysis which they prepare for scparatc but related projects including general pans,zoning:Barges, a'PLl devcluprount projects. This approach can eliminate repetitive discussions of the same issues anC focus the later EIR or negative declaration on the actual issues ripe for decisio at each level of environmental review," "(d)Where an EIR has been prepar d and certified for a p�ogram,plan,policy,or ordinance I consistent with the requirements of this section,any lead agency fnr i later project pursuant to or z consistent with the pmerarn,policy' or ordinance should bruit the EIR or negative declaration on the i later project to effects which: t (1)Were not examined as significa t effects on the caviroinncnt in the priui EIR; ...'''

A number of projects are proposed for the areas surrounding the project property, These include residential development to the north.ad commercial and ligh industrial to the east_ Interstate 80 and downtown Truckee lie to the south of e project ptopcity. The project site is a tree and shrub cov red hillside at an elev tion of between 6,000 feet and 6,190 feet above sea level, The project is on a generally southern exposµre with slopes across the project site ranging from 16%to 45%. i Flora includes yellow pine Pinus pondernsa ,Jeffery pine.Pin'is jefferyi,white fwAbies coneoloe, sage brush Armad:in tridentata,squaw carpet Ceanothus prostratu.8,and manztmita Aretostaphylos.

OS .... i I Evaluation of Environmental Impacts: j 1) A brief explanation is required for ailanswers except "No Impket"answers that are adequately supported by the information sources a lead agency cite&in the parentheses,followeng each question. A"No Impact"answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved(c.g.the project falls outside a fa�It rupture zone). A"No Impact"answer should be explained where it is based n project-specific factor as well as general standards(e.g.the project will not expose sensitive receptors to Pollutants,based on a project-specific screening analysis). 2) All answers must take account of the whole action involved,in�luding off-site as well as ou-sile,cumuladve as well as project-level,indirect as well 03 direct,and construction as well as operational impacts. 3) "Potentially Significant Impact"is appropriate if all effect is significant or potentially significant,or if the lead agency lacks information to make a finding of insignificance. I'there are one or more"Potentially. Significant Impact"entries when the detetminatioh is made,FIR is required. 4) "Potentially Significant Unless\Iitiga�ed"applies where the in corporation of mitigation measures has reduced an effect from"Potentially Significant Impact"to a"Less than Significant Impact". The lead agency must describe the mitigation measures,and riefly explain how they teducc the effect to a less than significant level (mitigation measures from Section X Il,"Earlier Analyses", tray be cross-referenced). 5) Earlier analyses may be used where,:pprsuant to the tiering,pro;ram FIR,or other CFQA process,an effect has been adequately analyzed ix an earlier FIR or negative declaration- Section 15063(c)(3)(D).

I. LAND USE ANI)PLANNING; This project involves the construction of a water storage,tank and pipeline to provide water service to existing and proposed development within the Town of Truckee. The Town of Truckee adopted a General Plan and associated envirronmental documents iji 1996 which included the area to be seared by the Bridge Street 6160 Tank. The General Plan sets fcrklt die land use and planning policies for the town, Provision of water supply facilities allows the lmplementatinn of the General Plan, I This project is included in the Diarists Truckee Water�ystem Water Master Plan Update and associated environmental documents. This project,along with all the projects proposed in the masterplan, is based on the general plan of the Town of Truckee. The project is consistent with tlic environmental plans and policies of the Town of TntckeIe The project will result in the construction of a new public water supply tank and undorground utilities. The new tank and pipeline will bG an acceptable land use based oil the land use[rod zoning dcsignaliuu of the project parcels. II. POPULATION AND HOUSIN� The Bridge Street 616t1 Water Storage Tank and pipeline will be designed to accomrodate the continued development of the District's water service area consistent with the population and housing projections of the Town of Truckee's general plan. The i)rojcct is needed to aocwnmudate the District's existing customers anc proposed new development in order to insure adequate supply during peak demand periods and to provide increased fire protecttion. The project does have lie potential to serve a population greater than th�current population in accordance with the District's master plan and the Town's general plan. Althnn�h the,project will accommodate growth, it is not considcicd to either 10 Sauers Ensineerins Inc. 5302656SZ4 P. 14 i1 directly or indirectly induce growth. Water Scrvicc would be made available to undeveloped areas only after complying with all other planning, land use, and environmental requirements imposed by the Town of Truckee. It is these planning and environmental agencies which arc responsible fit the level and direction of growth which w uld be accommodated'by this project. 11I. GEOPHYSICAL The project will roquitc a fairly extensive amount of grading to prepaie a level pad fur the tanks. The tanks will be placed on a pad cut into the hillsido. Tire l�cpth al the back of the cut will be approximately 30 feat. In utdoi to stabilize to exposed dmbankment,it is anticipated that a retaining wall will be cvnsu uctcd for a puitiun of the embankmeti<t and that the remainder of the embankment will he sloped back at a stable slope. Pipeline and cond{it constriction will involve excavation and backfill of tionchca. As is slanuaid with all District conItruction projects of this type, trenching and backlill upemtiuns will include s?rface restoration elrhe with paving or other permanent erosion control measures. Because of thq extent of the tank pad excavation,this is considered a potentially significant impact unless nougat d. fi The following mitigation meauurF is added to the project to reduce potential impacts to less than significant: g i r M-1. Prior to excavation at the tank site a gcotechnical investigation of the tank site will be conducted to determine the stability of ibe soil and rock material to be exposed during construction. The tank grading plan wi l specify the maximum slope for cut areas and engineered till slopes based on Cho slop stability determined by the gcotechnical investigation. IV. WATER j There will be an inemase in the amount of impervious surface as a result of this project including the tanks,access road and paved tank access area. This is expected to be approximately 49.000 square feet (1,1 acre). Drainage will flow from the impervious area to an infiltration basin adjacent to the tank site location. The infiltration basin will be sized to accommodate runoff from a 1-hour,20-year storm as defined by the Lahontan Regional Board. The basin will also be sized to accommodate the possible overflow from the tank as well as water being drained from the tank. This is considered a less than significant impact. Given the location, geology and depth of cut a snciated with the tank project, construction of the tank and underground utilities will not affect groundwater movement, quantity,or quality. Similarly,the project will not affect the amourd, current,or course of any surface water. During cnnstnictinn,there is a potential for excavated material to migrate offaite in the event of a rain atnrm event. Prior to site disturhilrg activities,the District will prepare a Report of Waste Discharge in rnmpl iance,with the Lahontan Regional Water Quality Control Board. Best management practices (RMPs)will be incorporated into'the project to protect Nyster quality during and after construction. This is considered a potentially significant impact unles mitigated. ; i e The following mitigation measur�s are added to the projnct to reduce potential impacts to less than significant: M 2. Temporary BMI.'Q will be ineorporatcd into the project dcsigu to be implemented before and during construction. B.MPs ipchide construction of silt fence down slope of tank excavation activities,covering tom orary spoils piles to piulmi,hum rainfall, and removal of speiismatorial to permarient locations protected from uffsilo migration. M-3. Permanent BMPs will include revegetati�on of exposed soil areas on the cut and fill slopes,asphalt pavement on access road and tank asses area, and permanent disposal I i i Sauers Ensineerins Inc. 53026566S4 P. 15 I I i of surplus excavated material at an acceptable location protected from offsitc migration. V. AIR QUALITY There will be no air emissions fr�m the water storage tank. Then;may be incidental emissions dutiug construction from contractor's operations including vehicles and mechanical equipment. Construction activities have the Potential to generate FM 10 cwissiuna thwugh tic rulcase of fugitive dust associated with grading and excavation activities. �he following tuitigativa muasures are added to the project to reduce potential impacts to less than siguificatet, i I M-4, Fugitive dust emissions resulting ftmn site cleating and any project improvements shall be minimized at all times utilizing cuntrul mcusujres including dust palliative,regularly applied water,graveled or pav�d haul roads,etc. Access or haul roads adjacent to the project must be treated as necessary';to prevent off-site migration and accumulation of dirt, soils,or other materials which can subsequently become enoaincd in ambient air,either ttom construction related vehicles or from any vehicle using adjacent affected roads. M-5. when Transporting material during site preparl tion or construction,measures shall be used to prevent materials from,spilling or blowing on street and highways. Earthen materials,if transported, shall be adequately sprayed with water or covered prior to transport onto public roads. Vegetative mat�riai shall be tapped as n'ecessary prior to transport. Specific control measures shall be note on improvement and/or grading plans. gg VL TRANSPORTATION/CIRCLTA11ON 3 During construction there will bean ircrease in vehicle Jrips to the project site associated with the contractor's activities- This is considered a less than significant impact. None of the construction will take place along any public streetts. The project will.not have any affect on emergency access, access to nearby uses,or alternative trap portation. The project will include parking or District vehicles. VII. BIOLOGICAL RESOURCES Construction of the storage tank and access road will involve clearing trees and hrnsh from approximately 2.1 acres. Prior to removal of marketable trees,the District will nhtain a:Public Utility Right of Way Exemption from the California Department of Forestry and Fire Protection. The removal of vegetation and replacement with the tank facilities would decrease the amount of available . habitat for birds and small mammals. The project site does not provide n vahlablc or unique habitat and the impact is, therefore,considered less than cignifi+nnt. The project site is not considered habitat for threatened or endangered species nfplants or nnimal�, The site contains no locally designated r species or nnhirnl communities. The site is in an upland area containing no wetlands. The project will have no impact on wildlife dispersal or migration. Vitt. FNERGY AND MINERAL RESOURCES The operation of the tank facilities will not involve the utilization of any significant energy resources. a IN. HAZARDS s During construction there is a ris of accidental release oaf hazardous substances such as fuel or oil from spillage. District construction contracts require the contractor to be prepared for such accidents and provide clean-up which in thus case would likely be hrrited to the project site. This is considered a less than significant impact. The project will have no impact on emergency responses. K 12 l4 Sauers Engineering Inc. 5302656834 P. 16 i I X. NOISE During tank and pipeline construction, there will be an increase in noise levels associated with contractor operations including operation of mcchanica�equipment such as a backlwo,generator,and compressor. Because of the distance to any sensitive receptors,thcsc noise levels are considered a less than significant impact. XI. PUBLIC SERVICES This project is based on and consistent with the gcncral platy of the Town of Ti ticket;including projections needed for public smI ices. The project willlnot icsult in lho need for new or altered government services. X11. UTILITIES AND SERVICE S VSTEMS The project will result in improvements to the District's water system by increasing the capacity and reliability of the system. Following construction, the project will not generate any appreciable amount of solid waste. Solid waste geneiated daring consrruction will be disposed of by the contractor at the local refuse transfer station. I i XIII. AESTHETICS The tank may be visible from lti rstate 80, The tank will be screened by a number of trees located around the tank site. The tank color will be chosen to blend with the surroundings. There will be no new lights associated with the project. 'Ibis type of facility may be considered to have a negative aesthetic effect,but given the existing tree screening and distance to any visual receptors,it is considered less than significant. XIV, CULTURAL RESOURCES (' An archeological review was conducted for the tank site;and access road. A cultural resources report is included as Appendix A. As indicated,no significant cultural resources were identified on the project site. Because the project involve excavation,there is a possibility of uncovering cultural resources not identified during the field review. The following mitigation measure will reduce the potential impact to less than significant. M-6. If artifacts,paleontological or cultural,or unu$ual amounts of stone,hone, o shell are uncovered during eons4uction activity,work$hall be halted and a qualified archaeologist shall be consulted for an on-site review. Mitigation measures,as recommended by the g archaeologist and approved by the District in ccordanec with Appendix K of the CFQA Guidelines, shall be implemented prior to recommencement of cnngtmcrion activity. If any bone appears to be hurrlan,California law marldates that the Nevada County Coroner and the Native American i-leriti ge Commission be cotjtacted. XV. RFC'RRATION The,project is based on and consistent with the general plan of the Town of Truckee including projectinns for needed recreational facilities. The project will have no impact on recreation facilities or nppnfitnities. XVL MANDATORY FINDINGS OF SIGNIFICANCE The project will take place on a rglstivcly small site witl limited vegetation or potential habitat and ; will not affect plant or animal species or habitat or eliminate prehistoric or historic resources. The project achieves both short ream and long term environmental goals by increasing water supply; water System reliability, and fire protection capability while avoiding potential sliuitagcs it,capacity, and allowing the implementation of adopted land use and environmental plans. Public water supply is one of many services needed to allow the continued orderly growth and , development of the Truckee area.i Issue:;related to growth and development including intensity, 13 'rF I Sauers Ensineerins Inc. 5902656834 P. 17 .. I I I density,location.and timing, among others, are the responsibility of the appropriate planning agency, in this case the Town of Truckee.

Washoe Trihc of Nevada and C'aliti�rui<j SUMMARY The Truckee Donner Public Utilities District (TDPUD) plans construction of a water storage tank on a 1.5-acre site, along with a 1200-foot pipeline within a 50-foot wide disturbance corridor. The 2.4-acre project area is near Truckee, California (Nevada County). The Town of Truckee requires the project sponsor to consider potential project impacts on heritage resources. Accordingly, a heritage resource inventory was conducted. Prefield research entailed a literature review of prehistoric and historic themes for the project area and included a review of prior archaeological research and of pertinent published and unpublished literature. A records search at the North Central Information Center (NCIC) at California State University Sacramento (CSLIs) was completed in order to identify any properties listed on the National Register, state registers and other listings, including the files of the State Historic Preservation Office (SI1PO). Oral history intcmct%s were conducted with (1) Kelly Shane, prior owner of the property and Sim-Neva Coiporetion. (2} memhers of the Truckee-Donner Historical Society, and (3) long-term residents of"fruckct'. An mchncolo0cal reconnaissance was conducted on July 2, 2001, with helpful field orientation by Keith Knibb of Sauers Fngineering. The entire project area was examined by systematically %calking parallel nansects at no greater than five-meter (15-foot) intervals. "the heritage resource inventory disclosed no significant prehistoric or historic sites. Isolated finds include: one fragment of historic light green bottle glass, observed in the rock outcrop smronnding the project area: and one historic high cut stump. These isolates are not significant heritage resources according to CEQA criteria. All of their potentially important information has been recovered with the preparation of this report. As the heritage resource survey disclosed no significant prehistoric or historic sites, features or artifacts, the project sponsor should not be constrained regarding heritage resources. Although the project area has been subject to systematic surface archaeological investigations, it is possible that buried or concealed heritage resources could be present and detected during project construction activities. In the event of fortuitous discoveries of additional heritage resources, project activities should cease in the area of the find and the project sponsor should consult a qualified archaeologist for recommended procedures. The Washoe Tribe of Nevada and California has been notified of the study findings. PROJECT DESCRIPTION, LOCATION AND SCOPE The Truckee Dormer Public Utilities District (TDPUD) plans construction of a water storage tank on a L5-acre site, along with a 1200-foot pipeline within a 50-foot wide disturbance corridor. The 2.9-acre project area is near Truckee, California(Nevada County). The project area falls within Township 17 North, Range 16 East, Section 10 (Figure 1). Current environmental review policies, in compliance with guidelines established by Placer County and the State of California (('EQA) require a consideration of the impacts of an undertaking on heritage resources. Such heritage resource studies are customarily performed in 1 a series of phases, each one building upon information gained from the prior study. Each of these phases are generally performed under separately negotiated contracts. INVENTORY: First, an archaeological reconnaissance is performed to inventory existing heritage resources and constraints. If properties are discovered and if they may be subject to project-related impacts, their significance must next be evaluated. EVALUATION: Next, and pending the outcome of the initial inventory, heritage resources subject to project-related impacts may need to be evaluated to determine their significance. Potential impacts to these significant resources can then be specifically assessed and detailed recommendations to mitigate impacts can be proposed. if project redesign to avoid impacts is unfeasible, then mitigation measures must be developed and implemented in order to recover the significant information contained within these heritage properties prior to project ground disturbance activities. IMPACT NIFf lGAJION AND DATA RECOVERY": A third and final phase may involve the implementation of mitigation measures recommended during the prior evaluation phase. Mitigation, or data recovery, typically involves additional field study, excavation, archival research, photo documentation, mapping, etc. Objectives of this heritage resource study are designed to satisfy antiquities requirements pertaining only to the initial i n,enlori, of heritage resources by: w heritage properties 1. conducting _reYteld research to determine the presence of known p P b P P and expected level of archaeological sensitivity of the project area; 2. performing an archaeological field surface survey of the project area; and 3. repoilkw preliminary field findings, to include a general assessment of'development- related impacts to inventoried heritage properties and mitigating measures to minimize the adverse impacts. Heritage resource significance and impact mitigation are generally performed under separate contract negotiations. BACKGROUND PHYSICAL ENk IRONNIEWT The project area consists of approximately 2.9 acres located along the moderately steep, northeast facing slope of a cinder hill northeast Truckee. The project area bounds an abandoned gravel pit, opclatcd by Sha-Neva ca. 1966 to 1968, and enlarged by Teichert ca. 1972 {Shane, 2 personal communication 719101). Utility lines pass above the project area, and modern discarded insulators on the ground. A downed telephone line crosses the project area; it may have once connected the cinder gravel pit with Sha-Neva offices to the east. Project topography is moderately steep with elevations ranging from 5990 to 6190 feet, "There is no flowing water on site; the Truckee River is located 2000 feet south of the property; "Grout Creek is approximately 600 feet to the southwest. The project area is situated in the Truckee Basin, an alluviated structural basin west of the Carson Range and east of the main crest of the Sierra Nevada. Low hills and ridges are Tertiary and Pleistocene volcanic rocks (Birkeland 1963) and valley floors are covered with relatively flat laying alluvial, glacial and glaciofluviatile deposits (Birkeland 19641). Holocene glaciation within the past 10,000 years was limited to the advance of small cirque glaciers. Pleistocene volcanic activity occurred between 2.3 and 1.2 million years ago. These flows are correlated with the Lousetown Formation, a series of early Quaternary basaltic rocks extruded from several local vents which underlie much of the Truckee Basin and its flanks (Birkeland 1963). The presence of tool stone-quality basalt in the project's vicinity (at Alder hill, due north of the project) attracted prehistoric populations into the general area for the purpose of stone tool manufacture (Elston, Hardesty and Clerico 1981; Elston, Hardesty and Zeier 1982; Rondeau 1982). However, basalt occurring natrually within the project area is coarse-grained and unsuitable tool stone. The study area lies �%ithin Storer and Usinger's (1971) Yellow Pine/Jeffrey Pine Belt_ In the Truckee Basin JefGey pine (Films iefbeyi) dominates forest stands and on the project site it shares dominance i%itb ponderosa pine (P. ponderosa) and lodgepole pine (P. murrayana). L!nderstory species i ncl udc sagebrush (Artemesia tridentata),bitterbrush(Pursia tridentata),current (Ribcs spp.), squaM CMIM (('canothus prostratus), and assorted fortis and grasses. It is doubtful that modern plant ((,r animal) communities closely resemble their pristine composition due to historic and modern disturbance. In prehistoric times the area is thought to have supported a luxuriant groyvtb of native hunch grasses which allowed an abundant large game population and provided a nutritious soince of seeds for use by early peoples. PREHISTORY A large vice divides the prehistory of the Sierra Nevada and adjoining regions into intervals marked h-� changes in adaptive strategies that represent major stages of cultural evolution (Elston 1982, 1986). In broadest terms, the archaeological signature of the Truckee Basin marks a trend from hunting-based societies in earlier times to populations that were increasingly reliant upon diverse resources by the time of historic contact (Elston 1982; Elston et at. 1977, 1994, 1995). The shift in lifeivays may he attributed partially to factors involving paleoclimate, a shifting subsistence base, and demographic change. 'I lie arelracolopy of the region was first outlined by IIeizer and Elsasser (1953) in their study of sites located in the "I ruckee Basin Martis Valley area. They identified two distinct 3 prehistoric lifeways Mach are believed to have once characterized the area's early occupants. Subsequent studies have further refined the culture history of the region (Elston 1971; Elston et al 1977). Some of the oldest archaeological remains reported for the Tahoe Region have been found in the Truckee River Canyon near Squaw Valley. These Pre-Archaic remains suggest occupation by about 9,000 years ago (Tahoe Reach Phase). Other Pre-Archaic to Early Archaic occupation dating from about 7,000 years ago was documented at Spooner Lake (Spooner Phase) near Spooner Summit overlooking Lake Tahoe. The most intensive period of occupation in the region may have occurred at varying intervals between 4,000 and 500 years ago (Martis Phases during the Early and Middle Archaic, and Early Kings Beach Phase during the Late Archaic). The protohistoric ancestors of the Washoe (Late Kings Beach Phase), also of Late Archaic times, may date roughly from 500 years ago to historic contact. NATIVE AMERICAN PERIOD The project area falls within the center of Washoe territory, with primary use by the northern Washoe or Wa She Shu (Downs 1966; Nevers 1976; Steward 1966). Washoe settlements are known to have existed in the project vicinity. Truckee town is at the location of the large Washoe village site of K'ubuna detde'yi' and below Truckee, at Trout Creek, was the village site of Pele ma'lam detde'vi'. The Washoe name for the Truckee River is a'wakhu wa't'a. The terraces on either side of the river at Truckee are known as tugiya (d'Azevedo 1956:51, 55). The Washoe once embodied a blend of Great Basin and California in their geographical position and cultural attributes. While they were an informal and flexible political collectivity, Washoe ethnography hints at a level of technological specialization and social complexity for Washoe groups, noncharacteristic of their surrounding neighbors in the Great Basin. Semisedentism and higher population densities, concepts of private property, and communal labor and ownership are reported and may have developed in conjunction with their residential and subsistence resource stability (Lindstr6m 1992). The ethnographic record suggests that during the mild season, small groups traveled through high mountain valleys collecting edible and medicinal roots, seeds and marsh plants. In the higher elevations, men hunted large game (mountain sheep, deer) and trapped smaller mammals. The 'Truckee River and tributaries were important fisheries year-round. Suitable toolstone (such as basalt) was quarried at various locales north and east of Truckee. The Washoe have a tradition of making long treks across the Sierran passes for the purpose of hunting, trading and gathering acorns. Archaeological evidence of these ancient subsistence activities are found along the mountain flanks as temporary small hunting camps containing flakes of stone and broken tools. In the high valleys more permanent base camps are represented by stone flakes, tools, grinding implements, and house depressions. The Washoe are part of an ancient Hokan-speaking residual population, which has been subsequently surrounded by Numic-speaking intruders, such as the Northern Paiute (Jacobsen 1966). Even into the 20th Century, the Washoe were not completely displaced from their traditional lands. I he contemporary Washoe have developed a Comprehensive Land Use Plan 4 (Washoe Tribal Council 1994) that includes goals of reestablishing a presence within the "Tahoe Sierra and re-vitalizing Washoe heritage and cultural knowledge, including the harvest and care of traditional plant resources and the protection of traditional properties within the cultural landscape (Rucks 1996:3). HISTORY As one of the major urban areas of Nevada County, Truckee has been what historians call an "urban frontier," or an urban area with many characteristics of the frontier. At least through the 1920s, what exposure Truckee gained outside the immediate area had to do with its many brothels, its violent discrimination against Chinese, and its general reputation as a rough lumber and railroad town. A history of the community of"Truckee is marked by the arrival of.Joseph Gray, who built a stage station near the present-day downtown in 1863. The "log house" shown on Figure 4 may be Gray's. Gray was soon joined by a blacksmith named S. S. Coburn, and the fledgling settlement of Gray's Toll Station was renamed Coburn's Station. This tiny way station grew from two structures in to a thriving town which accommodated emigrants, stagecoach travelers and freight wagons in route westward to California's gold fields and eastward to the Comstock Lode in Nevada. In 1868 Coburn's Station burned and the name was changed to Truckee. 'Throughout most of the 19th centurv, Truckee thrived on the related fields of lumber, railroading and ice. By the 1920s. this industrial economy and society had largely disappeared, due in major part to the relocation of the train switching yard to Roseville, the depletion of local timber supplies and the development of mechanical refrigeration. In its place, the community began to develop into a recreation-based economy, boosted by the completion of a good state highway over Donner Summit. The 1960 Winter Olympics at nearby Squaw Valley secured Truckee's position as a center point for year-round recreation. METHODS Archaeological research and field survey was conducted by Susan Lindstrom, Consulting Archaeologist to Sauers Engineering. Lindstrom has 28 years of professional experience in regional prehistory and history, holds a doctoral degree in anthropology/archaeology and has maintained certification by the Society of Professional Archaeologists (now Register of Professional Archaeologist) since 1981 PREEIELD RESEARCH Prefield rescarch entailed a literature review of prehistoric and historic themes for the project area. This included a review of prior archaeological research and of pertinent published and unpublished literature. Sharon Pace Arnold, native and long-term resident of Truckee and spokesperson for the Truckee-Donner Historical Society,was interviewed. Howard Snider, native and long-term resident of Truckee, also offered historic information during a series of telephone interviews. Representatives of the Washoe Tribe of Nevada and California have been notified 5 of the results of this study and asked to identify any potential Native American concerns (see Correspondence). A formal records search at the North Central Information Center, California State University at Sacramento (NCIC-CSUS) was initiated in order to identify any properties listed on the National Register, state registers and other listings, including the files of the State Historic Preservation Office (see Correspondence). References checked include archaeological sites and surveys in Nevada County, the National Register of Historic Places (listed properties (1996) and Determinations of Eligibility (1997), the California Inventory of Historic Resources (1976), California Historical Landmarks (1990 and updates), California Points of Historical Interest (1992 and updates), Gold Districts of California (1970), Survey of Surveys (Historic and Architectural Resources 1989), Directory of Properties in the Historical Resources Inventory (HRI 1997), Caltrans Local Bridge Survey (1989), Historic Spots in California (1966 and 1990) and Early California-Northern Edition (1974). According to NCIC-CSUS tiles, none of the project area has been subject to archaeological survey. Adjacent studies within a '/4-mile radius include: Jensen (1993, 2000), Lindstr6nn (2000), Noble (2000), Smith (1989) and NCIC study no. 2653. No previously recorded prehistoric sites are known to occur within the project area. Within a '/4-mile radius, prehistoric sites include: one lithie scatter (Coombs #1). There are no previously recorded historic sites within the project area. Historic sites located within Y4 mile of the project area include: two trash scatters (Coombs #2, Nev-457-11) and a historic camp site (Nev-456-H). FIELD RESEARCH An archaeological reconnaissance was conducted on July 2, 2001. The entire project area was examined by systematically walking parallel transects at no greater than five-meter (I 5-foot) intervals. Ground surface visibility was moderate to poor, being partially obscured by brush and pine duff. Cardinal directions were maintained by compass and pacing. Keith Knibb of Sailers Engineering provided helpful field orientation. The archaeological coverage map is roughly keyed to this coverage strategy (Figure 2). RESULTS The heritage resource inventory disclosed no significant prehistoric or historic sites. Isolated finds include. one fragment of historic light green bottle glass, observed in the rock outcrop surrounding the project area: and one historic high cut stump. These isolates are not significant heritage resources according to CEQA criteria. All of their potentially important information has been recovered with the preparation of this report. As the heritage resource survey disclosed no significant prehistoric or historic sites, features or artifacts, the project sponsor should not be constrained regarding heritage resources. Although the project area has been subject to systematic surface archaeological investigations, it is possible that buried or 6 concealed heritage resources could be present and detected during project construction activities. In the event of fortuitous discoveries of additional heritage resources, project activities should cease in the area of the find and the project sponsor should consult a qualified archaeologist for recommended procedures. The Washoe Tribe of Nevada and California has been notified of the study findings. The heritage resource inventory disclosed one historic site (Site 1), a sawmill building and associated outbuilding constructed and operated ea. later 1940s, and two historic isolated features, a trash scatter consisting of barrel hoops, bedsprings and baling wire (IFI), and a wooden Emigrant Trail marker (IF2); however, the trail does not pass through the project area. These heritage resources are summarized below, with detailed discussions and mapped locations contained in the attached confidential appendix. A few high-cut stumps, remnant of historic logging activities, were noted but not formally recorded. None of these stumps are suitable for dendrochronological (tree-ring) dating as their bark and outside wood have weathered.

The storage tanks will provide approximately 4,000,000 gallons of storage in two tanks. Finding: It is hereby found that the above named project will not have a significant effect upon the environment. Initial An initial study of this project was undertaken and prepared in accordance with Article Study: V of the District's local environmental guidelines and Section 15063 of the EIR Guidelines for the California Environmental Quality Act for the purpose of ascertaining whether this project might have a significant effect upon the environment. A copy of such initial study is attached hereto and incorporated herein by reference. Such initial study documents reasons to support the above finding. Mitigation The following mitigation measures have been included in the project to avoid Measures: potentially significant effects: M-1. Prior to excavation at the tank site a geotechnical investigation of the tank site will be conducted to determine the stability of the soil and rock material to be exposed during construction. The tank grading plan will specify the maximum slope for cut areas and engineered fill slopes based on the slope stability determined by the geotechnical investigation. M-2. Temporary BMPs will be incorporated into the project design to be implemented before and during construction. BMPs include construction of silt fence down slope of tank excavation activities,covering temporary spoils piles to protect from rainfall, and removal of spoils material to permanent locations protected from offsite migration. M-3. Permanent BMPs will include revegetation of exposed soil areas on the cut and fill slopes,asphalt pavement on access road and tank access area,and permanent disposal of surplus excavated material at an acceptable location protected from offsite migration. M-4. Fugitive dust emissions resulting from site clearing and any project improvements shall be minimized at all times utilizing control measures including dust palliative,regularly applied water,graveled or paved haul roads, etc. Access or haul roads adjacent to the project must be treated as necessary to prevent off-site migration and accumulation of dirt, soils, or other materials which can subsequently become entrained in ambient air, either from construction related vehicles or from any vehicle using adjacent affected roads. M-5. When transporting material during site preparation or construction, measures shall be used to prevent materials from spilling or blowing onto street and highways. Earthen materials, if transported, shall be adequately sprayed with water or covered prior to transport onto public roads. Vegetative material shall be tarped as necessary prior to transport. Specific control measures shall be noted on improvement and/or grading plans. M-6. If artifacts, paleontological or cultural, or unusual amounts of stone, bone, or shell are uncovered during construction activity, work shall be halted and a qualified archaeologist shall be consulted for an on-site review. Mitigation measures, as recommended by the archaeologist and approved by the District in accordance with Appendix K of the CEQA Guidelines,shall be implemented prior to recommencement of construction activity. If any bone appears to be human, California law mandates that the Nevada County Coroner and the Native American Heritage Commission be contacted. M-7. Trees shall be planted on the downslope side of the tank in the fill slope areas. The number, location, and spacing of the trees shall be determined following design of the grading plan and determination of the extent of the fill slope areas. Tree size and species shall be selected so as to insure a high likelihood of survival given the competition from existing trees. M-8. .(Truckee General Plan Land Use Policy 2.3) - To provide for projected population growth in an efficient manner, accommodate development at the highest densities in infill areas, consistent with the goals for environmental protection and land use compatibility. M-9. (Truckee General Plan Land Use Policy 3.1) - Work with all special districts, including the Tahoe-Truckee Unified School District, to ensure that development within the Town is coordinated with provision of services. Date: By: Peter L. Holzmeister, General Manager r Truckee Donner Public Utility District Bridge Street 6160 Water Storage Tanks MITIGATION MONITORING PROGRAM The Mitigation Monitoring Program insures the enforcement of mitigation measures included in the project's negative declaration. The Environmental Initial Study identifies mitigation monitoring responsibilities including method of implementation, timing of implementation, and responsible party. The following Mitigation Monitoring Program Checklist provides a method to verify implementation of mitigation measures. Typically, mitigation measures are implemented at three phases of a project; project planning and design, project construction, and following project completion. The checklist shows verification of implementation at each phase for each mitigation measure.
