PROJECT DESCRIPTION, LOCATION, AND ENVIRONMENTAL SETTING

CHAPTER 1.0 PROJECT DESCRIPTION, LOCATION, AND ENVIRONMENTAL SETTING 1.1 Pojct Objctivs Sction 15124(b) of th Califonia Envionmntal Quality Act (CEQA) Guidlins quis an Envionmntal Impact Rpot (EIR) to ppa a statmnt of objctivs sought by th poposd pojct. Th objctivs assist th County of San Digo (County), as lad agncy, in dvloping a asonabl ang of altnativs to valuat in th EIR. Th pojct objctivs will also aid dcision-maks in ppaing findings o a statmnt of oviding considations, if ncssay. Th statmnt of objctivs also includs th undlying pupos of th pojct. Th following a th pojct objctivs st foth by th poposd pojct: 1. Enhanc public accss to th lak and th amnitis of th pak. 2. Rsto and nhanc th natual aquatic functions of th lak. 3. Impov habitat fo aquatic and avian spcis. 1.2 Pojct Dsciption 1.2.1 Lak Basin Rcontouing Th pojct poposs xcavation and gading of appoximatly 226,000 cubic yads of silt and sdimnt to contou th lakbd, dpn th ast and wst lak basins, and povid tntion basins (Tabl 1-1). Appoximatly 27,000 cubic yads of th xcavatd lak matial would b usd to stabiliz th banks of th lak basins and to cat gadd mounds suounding th basins, and fo landscaping and habitat cation. Th balanc of th matial (appoximatly 199,411 cubic yads) would b xpotd off-sit. Th gading would b dsignd to cat shallow aas in th ast lak basin fo nsting and fldgling young bids. Th pojct would also install undwat fatus to povid shlt fo fish. Following gading, th basins would b lind with bntonit clay up to th wat sufac lvl in th majoity of th wst basin and two ft blow th wat sufac lvl in th ast basin. Th bntonit clay lin would assist in duction of goundwat pcolation whil impoving wtland habitat. Th banks of th basins would b stabilizd by th placmnt of a lay of cobbl ock xtnding fom on foot blow th wat sufac lvl in th wst basin and two ft blow th wat sufac lvl in th ast basin, to a dpth of appoximatly fiv ft in both basins. Following constuction, both basins would fatu a maximum dpth of 10 ft, with th upp lvl of inundation occuing at an lvation of 394 ft abov man sa lvl. Th lak dpning would b conductd in two initial phass, with Phas 1 focusd on th ast basin and Phas 2 focusd on th wst basin. Phas 1 would includ dwating of th ast basin by pumping any xisting wat to th wst basin, th moval of matial fom th ast basin; xcavation and contouing of th ast basin, including cation of a sdimnt basin on th ast sid of th ast basin; cation of mounds; off-sit xpot of th maining xcavatd matial; dainag impovmnts; wat aation; wat ciculation; and landscap and iigation impovmnts. Phas 2 would includ moval of lak wat fom th wst basin. This would allow fo dying of th sdimnt in th wst basin. Aft dying, th sdimnt would b movd fom th wst basin, usd fo contouing and cation of mounds, and th maind would b xpotd offsit. A sdimnt basin would b catd on th noth sid of th wst basin. Som matu ts Lindo Lak Rstoation Pojct Supplmntal EIR Pag 1-1

would nd to b locatd o movd to allow fo th gading of th basins. Nw plantings and iigation would occu aound both basins. Raw wat fom th Hlix Wat Distict piplin would b usd fo th initial fill of th dpnd lak. Post-constuction wat lvls would b maintaind by using goundwat fom on-sit wlls. Dainag Impovmnts Dainag impovmnts would includ xtnsion of xisting stom dain pips; addition of stom dain inlt and outlt potction o ngy dissipats; and cation of sdimnt basins. Potction would b addd to cub inlts along oads locatd within and adjacnt to th pak land to captu sdimnt and duc flow ats and osion. Th is an xisting box culvt undnath th causway that histoically allowd wat to flow btwn th basins duing flood vnts. Th pojct poposs to plac this shallow bottom box culvt with a nw culvt that would povid a dpnd sction along with two additional 48-inch culvts though th causway that would allow wat and aquatic lif to ciculat btwn th two basins. Sdimnt basins a also poposd to duc futu sdimnt accumulation within th main lak basins. Ongoing maintnanc of th lak basins would qui annual monitoing of sdimnt lvls and gula moval of sdimnt on an as-ndd basis to maintain basin dpths. Each basin would includ maks to idntify sdimnt dpths. Whn accumulatd sdimnt achs a dpth of 12 inchs in any pat of th lak bottom, it would b movd. Pak Landscaping Impovmnts As dscibd abov, th lak basin contouing would poduc xcavatd silt and sdimnt that would b usd to cat landscapd mounds suounding th basins. In addition to ths mounds, oth poposd pak landscaping impovmnts includ installation of two nw floating fishing pis xtnding fom th wst and ast sids of th causway, two bid watching stations, dcoativ boulds, and ADA (Amicans with Disabilitis Act) impovmnts. Additionally, th pak s iigation systm would b modifid to povid fo tmpoay iigation of nw plantings as wll as sasonal and ongoing dought condition iigation. Accss and Ciculation Impovmnts Poposd pak accss and ciculation impovmnts includ th following: moval and placmnt of a pfabicatd bidg on th noth sid of th wst basin, installation of a nw pfabicatd pdstian bidg on th wstn sho of th wst basin that would connct th Laksid Community Cnt to th boathous island; a simulatd boadwalk to connct fom bhind th Community Cnt to th noth paking lot; and constuction of a stabilizd dcomposd ganit path aound th basins to impov ADA accss. Constuction Activitis Th lakbd dpning activitis (Phass 1 and 2) a anticipatd to tak appoximatly 36 months. Equipmnt poposd to b usd fo both phass includs xcavatos, backhos, dozs, loads and smi nd dumps. Bst managmnt pactics (BMPs) would b usd fo osion contol duing impovmnt activitis. Poposd BMPs includ th us of tmpoay constuction ntancs, fnc, fib olls, silt fnc, gavl bags, and stom dain inlt potction. Th maining pojct impovmnts (.g., stom dainag systm, public accss, ciculation, Pag 1-2 Lindo Lak Rstoation Pojct Supplmntal EIR

public amnitis) would b implmntd as pat of Phas 2, which is anticipatd to tak 16 months. 1.2.2 Pojct Backgound Lindo Lak is dividd into a similaly-sizd ast basin and wst basin, spaatd by an appoximatly 30-foot-wid causway that uns noth-south though th middl of th lak aa. Wat flow btwn th ast and wst basin is facilitatd by a mtal pip and valv undnath th causway. Th lak was oiginally fd by th wats of Quail Canyon Ck; howv, th ck has sinc bn dammd to cat naby Lak Jnnings. Wat supply to th lak is now limitd to uban and sufac unoff within th immdiat vicinity of th lak, fquntly laving th shallow ast basin of th lak in a dy stat. Ov tim, th lak basins fill with silt and sdimnts as thy collct unoff fom th suounding dainag aa. This aiss th lakbd lvation, which sults in shallow wat dpth and sasonal dying of th ast basin. By xcavating th silt and sdimnt, and thn gading and contouing th lakbds, th basins can b dpnd, allowing th lak to fill with a gat volum of wat. An EIR fo impovmnts to Lindo Lak Pak was ctifid by th County Boad of Supvisos on May 27, 1976. Th poposd impovmnts includd th following: th addition of th paking lots, picnic tabls, a fishing pi and a owboat concssion, location of th boat hous, as wll as, th dpning of th southwstn and wstn lak basins. Th dpning of th lak quid th movmnt of appoximatly 94,000 cubic yads of matial. Th matial was usd as fill fo shaping of th lak sholin and fo distibution at vaious locations acoss th pak popty. Th pojct also involvd using non-pmabl matial to sal th lakbd. On-sit wll wat and wat puchasd fom th Laksid Iigation Distict was poposd to fill th lak. Th ctifid EIR found mino ffcts to taffic ciculation, biology, vcto contol, and hydology. Ths ffcts w all dtmind to b mitigatd o avoidd to a lvl blow significanc. Subsquntly, a Supplmntal EIR (SEIR) was ppad fo impovmnts at Lindo Lak Pak in confomanc with a Pak Mast Plan datd Januay 1983. Th poposd impovmnts includd th following: th addition of 185 paking spacs, two nw pak ntancs, th addition of a 1,500-squa-foot community cnt building, th addition of a spay fountain/bandstand plaza, location of th tnnis couts, th addition of a multipupos fild, nw hossho aas, a nw tot lot, xpansion of th pacous, pdstian, qustian, and hiking tails, nw goup picnic tabls, novation and constuction of stooms, nw tuf and iigation systms, and th daining and dpning of th astn lak basin with distibution of th xcavatd matial fo us lswh on th pak popty. Wll wat was poposd to supplmnt and maintain th wat lvl in th ast basin, whil wat ciculation was impovd by using xisting lak wat fo tuf iigation. Th SEIR was ctifid by th County Boad of Supvisos on Fbuay 28, 1984. Th SEIR addssd potntial impacts to taffic and ciculation, nois, and hydology/wat quality. No significant nvionmntal ffcts w idntifid fo this pojct. 1.3 Pojct Location Th pojct sit is locatd within th Lindo Lak County Pak at 12660 Lindo Lan (Asssso s Pacl Numb 394-180-03-00), and covs appoximatly 57.46 acs.

This SEIR valuats th potntial nvionmntal impacts associatd with implmntation of th cuntly poposd pojct. This is a supplmntal EIR to th oiginal EIR (1976) and SEIR (1984), dscibd abov, ppad fo ali stoation activitis at Lindo Lak County Pak. Public Rviw and Paticipation Pocss Pusuant to Sction 15082 of th Stat CEQA Guidlins, a Notic of Ppaation of th SEIR was issud on Mach 10, 2017 to infom psons and oganizations that may b concnd with th nvionmntal ffcts of th pojct, and to qust public commnt on th pojct and th contnts of th SEIR by wittn cospondnc o paticipation in a plannd scoping mting (Appndix A). Public agncis with spcific statutoy sponsibilitis w qustd to indicat thi spcific ol in th pojct appoval pocss. On th vning of Mach 16, 2017, a public scoping mting hostd by psntativs fom th County Dpatmnt of Public Woks and th Dpatmnt of Paks and Rcation was hld at th Laksid Community Cnt to discuss th pojct and th scop of th contnts of th SEIR. At th mting, it was potd that ppaation of nvionmntal studis was cuntly undway fo th following issu aas: biological soucs, cultual soucs, gnhous gas missions, gology and soils, hydology and wat quality, and taffic. Public commnt was civd and documntd in th mting minuts. Pag 1-6 Lindo Lak Rstoation Pojct Supplmntal EIR

This SEIR will b mad availabl fo viw by mmbs of th public and public agncis fo 31 days to povid commnts on th sufficincy of th documnt in idntifying and analyzing th possibl impacts on th nvionmnt and ways in which th significant ffcts of th pojct might b avoidd o mitigatd, as statd in CEQA Guidlins, Sction 15204 (14 CCR 15000 t sq.). As th dsignatd lad agncy, th County is sponsibl fo ppaing this documnt. Th dcision to appov th poposd pojct is within th puviw of th County Boad of Supvisos. Whn dciding whth to appov th pojct, th County will us th infomation includd in this SEIR to consid potntial impacts on th physical nvionmnt associatd with th pojct. Th County will consid wittn commnts civd on th SEIR in making its dcision whth to ctify th SEIR as complt and in complianc with CEQA, and also whth to appov o dny th pojct. Envionmntal considations and conomic and social factos may b wighd to dtmin th most appopiat cous of action. If th SEIR is ctifid and th pojct appovd, agncis with pmitting authoity ov all o potions of th pojct may us th SEIR as th basis fo thi valuation of nvionmntal ffcts of th pojct and appoval o dnial of applicabl pmits. 1.6 Pojct Inconsistncis with Applicabl Rgional and Gnal Plans Th pojct was viwd fo consistncy with th following applicabl gional and gnal plans: County of San Digo Gnal Plan Laksid Community Plan County Zoning Odinanc County of San Digo Paks Mast Plan This viw did not idntify any inconsistncis with ths plans. 1.7 List of Past, Psnt, and Rasonably Anticipatd Futu Pojcts in th Pojct Aa A list of past, psnt, and asonably anticipatd futu pojcts in th pojct aa was ppad in consultation with County staff that svs as th basis fo th cumulativ impact analysis. A dsciption of ths pojcts is povidd in Tabl 1-2, and th locations of ths pojcts a psntd in Figu 1-3. 1.8 Gowth Inducing Impacts CEQA quis that a discussion b ppad in nvionmntal documnts gading th ways in which a poposd pojct could b gowth inducing. CEQA Guidlins Sction 15126.2(d) idntifis a pojct as gowth inducing if it would fost conomic gowth o population gowth, o sults in th constuction of nw housing, ith dictly o indictly, in th suounding nvionmnt. Nw mploys fom commcial o industial dvlopmnt, schools, golf couss, and nw population fom sidntial dvlopmnt psnt dict foms of gowth. Indict foms of gowth includ th dmand fo additional goods and svics associatd with th incas in pojct population that would duc o mov bais to gowth in oth naby locations. Lindo Lak Rstoation Pojct Supplmntal EIR Pag 1-7

Und CEQA, gowth inducmnt is not ncssaily considd dtimntal, bnficial, o of littl significanc to th nvionmnt. Th gowth inducing potntial of a pojct could b considd significant if it fosts gowth o sults in a concntation of population in xcss of what is assumd in adoptd mast plans, land us plans, o pojctions mad by gional planning agncis, such as th San Digo Association of Govnmnts. Additionally, a pojct could b considd gowth inducing if th pojct povids infastuctu o svic capacity to accommodat gowth byond th lvls cuntly pmittd by local o gional plans o policis. Th poposd pojct is limitd to impovmnts of Lindo Lak and would not constuct any nw housing o businss that would induc population gowth, no xtnd oadways o infastuctu that would indictly induc population gowth. Th poposd pojct would not chang th xisting land us at th pojct sit fom that of a County Pak, no would it affct th xisting o plannd zoning and land us dsignations of th suounding aas. Although th poposd pak impovmnts would b bnficial to naby sidnts who us th pak facilitis, thy would not induc population gowth, ith dictly o indictly.
