The sewage conveyance and treatment system of which the proposed prOject 15 part 15 known as the Coastal Interceptor Sewer System (CIS). The CIS 15 a portIon of the entIre wastewater conveyance system operated by the City of Los Angeles, the extent of wluch is over 6,500 miles of mainlme sewer and nearly 60 pumpmg stab.ons. The City of Los Angeles treats approxunately 420 nulhon gallons per day of wastewater at lts fOUI treatment plants. Over 3.5 million people are served by tlus system. Smce 1946, the Clues of Los Angeles and Santa Maruca have been party to numerous contrach1al agreements with respect to use of certain of their sewerage facilitIes Generally, the agreements have prOVIded for the CIty of Los Angeles to chscharge sewage from the Sunset Pumpmg Plant semce area mto CIty of Santa MOIUca conveyance and pumpmg systems en route to ultImate treatment at the Hypenon Wastewater Treatment Plant located south of the Playa del Rey chstnct of the City of Los Angeles The Sunset Pumpmg Plant semce area generally mc1udes PaCIfic p;:J h~ades and other chstricts northerly of the City of Santa Monica. The sewage conveyance system is routed through Santa Moruca from the northwest corporate boundary through the Moss Avenue Pumpmg Stahon near the ,., City of Santa Monica 1-1 Moss Avenue Sewage Pumpmg Station and Coastal Interceptor Sewer Subsequent Indial Study I MItIgated Negative Declaration Section 1.0 Introducbon Santa Maruca PIer, and reenters the CIty of Los Angeles system at the southwest corporate boundary at Veroce. In return for tins routing, the Gty of Santa Maruca may chscharge sewage mto the CIty of Los Angeles system for conveyance to and treatment at the Hypenon Wastewater Treatment Plant. The agreement now in effect was executed on February 21, 1964, and amended on October 3, 1966 The agreement and amendment prOVIde that capItal and operahon and management (0&.1\1) costs will be borne by the cines III proportIon to therr capacity reqUlfements For the past ten years, the CIty of Los Angeles has been negOhating new contract terms WIth a number of subscnbmg agenCIes, mc1udmg the CIty of Santa Monica, that discharge sewage to the Hypenon Plant. It IS expected that a new agreement will be fInalized and executed m February 1999 TIus new agreement ","'1il mclude new formulae for deternuning capItal and O&M cost sharmg between the cibes. The City of Los Angeles will bear the largest share of capital and O&M costs, and "will thus conbnue to exercise approval power relatmg to capaCItIes, design features and construchon. The PacifIc Coast HIghway Force Mam carnes sewage from the Sunset Pumpmg Plant semce area southward The conveyance system then becomes a gravity main pnor to entenng Santa Maruca The Sunset plant and PacIfic Coast HIghway Force Mam have been mandated as a result of a legal settlement entered mto m 1990 between the CIty of Los Angeles and the State Water Quahty Control 'Board. ThIs Settlement Agreement outlines a program of proJects and adn:urustranve act:I.ons that collectIvely would greatly Improve the performance rehabIhty of the Clty'S wastewater collectIon system In add1bon to the Sunset Pumpmg Plant, the eXIStIng North Pulga and Temescal Canyon puro.pmg plants were to be rehabilitated and an emergency underground storage facility was constructed to contaIn three hours of peak wet weather flow 1 Except for a separanon of the Pulga Canyon Sewer LateraJ., the scope of the project r~mamed unchanged. As of the wntmg of this report, the upgrades have or 'W1ll have been completed by November 19982 Subsequent to the 1994 Northndge Earthquake, substantIal earthquake-related damage was discovered to the upstream reach of the CIS "'-'lthm Santa Monica In September 1995, the Federal Emergency Management Agency j OffIce of Emergency ServIces approved a damage survey report (DSR) authorizIng repaIrs. Pnor to and concurrent WIth the approved DSR for the upstream reach, staff had scheduled repaIrs and upgrades to the eXIStIng Moss Avenue Pumpmg StatIon and to the existIng flow monitonngj samphng statIons located in nghts-of-way at the northerly and southerly aty Imuts In the spnng of 1996, proposals for the design of all of the aforemenhoned work that was requested for both earthquake and non-€arthquake-related repaJIS The Santa Monica CIty Councll approved the design contract in July 1996, and prp liminary deSIgn started shortly thereafter. Part of the design process mcluded several Joint workshops WIth City of Los Angeles staff Under the terms of a 1964 agreement, the City of Los Angeles IS responsible for its farr share of the costs of the capital Improvements to the CIS .....itlun Santa Maruca. In a March 1997 workshop, during whIch Santa Moruca unveiled Its Year 2050 plan for replacing the two hnes m PaafIc Coast Highway WIth a new smgle hne and replaang both the Moss Avenue Pumping StatIon and the momtonngj samphng stations W1th new structures, City of Los Angeles staff requested that Santa Maruca mvestigate the 1 CIty of Los Angeles, Sunset Pumping Plant and Force Main in Pacific Coast HIghway FEJR 1992 2 Martmez, 1998 r City of Santa Momca 1.2 Moss Avenue Sewage Pumpmg Station and Coastal Interceptor Sewer Subsequent /nmal Study / MitIgated NegatIve DeclaratIOn Secbon 1 0 Introducbon adequacy of the eXlstmg downstream reach of Its CIS ill Ocean Avenue, PICO Boulevard and ~am Street A closed drewt televislOn mspection of tlus dO"\o\.'TIStream reach revealed that slgmftcant earthquake- related damage was eVIdent resultmg m FEMA authonzmg reparrs to the Ocean Avenue, PICO Boulevard and Mam Street bnes shortly thereafter The Santa Momca G.ty COUTIol approved the mcreased design scope and costs m June 1997. Dunng the same tIme-frame, staff was adVISed that to construct the new pumpmg stan on without damagmg the adjacent housmg project located to the south (PrOject New Hope), the City would have to advance the construcbon of the station's structural shell ahead of the construchon of the housing project The selected method was to proceed WIth a deSIgn-build contract of the new underground structure, whereby the desIgn of the stabon would be completed as the stanon was constructed. Staff advanced the shell's emrrronmental reVIew under CEQA, a negahve declaration was ISsued and the Califorma Coastal ComrrusslOn Issued a categoncal exemphon under its "Repau, Mamtenance and Utility Hook-up" exclusion. On October 28,1997, the Santa Momca CIty Conncil walved compenhve bidding, authonzed the desIgn-bulld contract, and certIfJ.ed the negatIve decIaratlOn ConstructIon started shortly thereafter Durmg a March, 1998 workshop, Santa Momca staff presented Its final deSign for the do'WOStream reach to the CIty of Los .Angeles. Gty of Los Angeles staff requested that Santa Monica's porhon of the CIS be redeSIgned for Year 2090 flows rather than the Year 2050 flows preVlously agreed upon In a subsequent meebng WIth the CIty of Los Angeles, It was requested that the porhon of the CIS Withm Santa Moruca be deSIgned to also accommodate all dry-weather surface runoff wIuch is to be dIverted from dIschargmg directly onto the beaches north of Santa Maruca to the CI? for treatment. The CIty of Los Angeles requested that a combmed dry weather runoffj sewer capaaty of 32 mgd be proVIded. At the hme of the request, the structural shell of the Moss Avenue Sewage Pumping Stahon was bemg constructed and only a combined flow of 26 mgd could be accommodated. Environmental Review History In October 1992, the City of Los Angeles adopted a Final EnVIronmental Impact Report on the Sunset Pumpmg Plant and Force Main m Pacmc Coast H1ghway The project was deSIgned to rectIfy sewage spills and other malfunctIons that had occurred along the CIty of Los Angeles' Coastal Interceptor Sewer. The project was one of a number of actions mandated as a result of a legal settlement entered mto m 1990 between the City of Los Angeles and the State Water QualIty Control Board. It analyzed the need for repaIl' and expanslOn of facihhes that collect and convey sewerage that passes through the proposed project from a Gty of Los Angeles Bureau of Engmeenng ServIce area northerly of the CIty of Santa Moruca In July 1994, the Gty of Santa Monica filed a NotI.ce of Exemption under CEQA for citywide sewer reparr to address damage from the 1994 Northridge Earthquake. The Gass 1(b) categorical exempnon covers the "repatr, mamtenance, or mmor alterahon of eXIstmg publzc or pnvate structures, faallheS, mechanu:al equlpmen t, mvolvmg neglzgzble or no expan510n of use beyond that prevwusly eXIshng, mcludmg eXlshng faalihes ofboth m'Z.'estor and pubbcly-owned uhlztzes used to provuJe .sewerage, or other publzc uhlzty sennces." The exemphon had mtended to serve for the replacement and upgrade of the sewerage conveyance lmes from the north city corporate boundary to the Moss A venue sewage pump stahon and south of there to the south CIty lmuts. r City of Santa Monica 1-3 Moss Avenue Sewage Pumpmg Station and Coastal Interceptor Sewer Subsequent Imtlal Study / Mitlgated NegatIve DeclaratIon Section 1 0 Introduction In March 1997, the CIty of Santa Moruca bled an Irnhal Study and NeIghborhood Impact Statement for the Moss Avenue Sewage Pumpmg Stahon Project. A NegatIve Declarahon was certIfted by the CIty Council on October 28, 1997 It addressed the reconstrucbon of the sewage pumpmg statIon reqUIred by the CIty of Los Angeles Bureau of SamtatIon at that trme However, no above-grade elements were proposed or evaluated as part of the ongmal analysIS.

The CIty of Santa Momca has not adopted thresholds of slgruficance for shadow nnpacts For purposes of thiS analYSIS, shadow Impacts are conSIdered slgruhcant 1f the proposed project would create shadows that substantIally reduce rooftop solar access for any adjacent structures. Impact Analysis. The Moss Avenue sewer pumpmg statIon will not reduce rooftop solar access for any adjacent structures smce the proposed sewer pumpmg facility would have hnuted above grade elements The only neIghbor that could be potentIally affected by shade IS the resIdential development at Project New Hope ThIs would only occur dunng a late afternoon sun condIhon where a low solar angle IS expenenced. In the Santa Moruca area, flus would only occur when the sun was at Its northernmost posrb.on m the henusphere (e g the duratIOn summer solstIce) GIven that Project New Hope will be a five-story structure, no structures at the Moss Avenue project SIte are hIgh enough to block sun from the apaitil-lent rooftop dunng 1200 or 1500 hours Dunng wrnter solstIce, the shadow angle would effect the hills lope adJommg the Pacrfrc Coast HIghway Access Road, not Project New Hope Durmg summer solstIce, the shadow length from the exhaust pIpe enclosure and metal canopy, the tallest structure on the project SIte, would be 15 feet and not long enough to reach Project New Hope. Therefore, no slgmhcant shadow nnpacts are antIcIpated No nutIgatIon measUfeS are necessary. Cumulative Impacts. The proposed project would not generate sIgruftcant shadow effects and would not affect any propertIes outsIde the rmrnedlate area of the project SIte Therefore, It would not contnbute to cumulatIve shadow unpacts. 4.3 CONSTRUCTION Errt:CTS Setting.

A-4. ENERGY Accordmg to the 1996 MEA, both Southern Cahforma and The Gas Company expect to meet the energy needs for expected future development Wltrun the CIty of Santa MOnIca. The mcrease ill capacrty of the proposed project ""J..ll result m a 33% mcrease of requrred energy: from 750 kW to 1000 kW. TIns mcrease would not result ill the use of a conSIderable amount of fuels or energy and would not result m a slgrufIcant rncrease m demand for eXIStIng energy supphes A-5. NATURAL RESOURCES The project would not result ill a slgnmcant mcrease ill the rate of natural resource consumpb.on nor rn a slgruhcant deplehon of any nonrenewable natural resource (see A-5) r City of Santa MOnica A-l A-6 RISK OF UPSET The are no explOSIve or hazardous substances assoClated Vvl.th the operatIon of the proposed sewage pumpmg statIon and will not mterfere WIth any emergency response plan.

The project In Itself would not remove other bamers to gro\\'th and so would result In a consIderable change m the denSIty, dIStrIbuhon, or growth rate of the human populatIon m the area The project does not Involve the relocatIon of persons, employment or busmess A-9 HOUSING The proposed proJect Mould not create a sIgmncant demand for new hOUSIng and "\\'111 not have a sIgruficant adverse Impact on the availability of rental housmg In the commuruty. A-IO RIGHT OF WAY The proposed proJect would not result m reduced lot area, access, off-street parkmg, or the creatIon of an abrupt grade dJiferenhal between pubhc and pnvate property In the frrushed cond1tron, the project would prmrlde four addItIonal off-street parkmg spaces A-ll TRANSPORTATION/CmCULATION Parlang Impacts. Parkmg reqUIrements are deternuned based on CIty zoning ordmances, although vanances may be granted dependmg upon the partIcular project SInce tlus project IS an amendment to the preVIously approved project and on-sIte parkmg demands remam unchanged, normal operabons at the facility would not create an nnpact to parkIng Therefore, no nutIgahon IS reqUIred for day-to-day operatIon of the facility. Parkmg at the Moss Avenue Sewage PumpIng facility would be conSIstent WIth CIty code requll'ements, and parkIng unpacts are not conSIdered sIgruf1cant Traffic and Circulation Impacts The above ground elements of the proposed project would not result In any rmpacts to transportahon or crrculabon except during construcbon.
