  1. 1. TrafficStudyNotes - Danziger 1. 248du w/546 parkingspaces.2.2 spaces/du – how doesthiscompare w/Anzaapartmentsonsite parkinggiventhe offsite loadtheycurrentlyimpose? 2. Crenshaw/PCH–lessthanD LOS withoutproject –unmitigatableimpact?? 3. Findingthatthere isno LOS degradationin2019 giventhe projectatthe keyintersections ignoresin-flightandpotential projects&cumulative impactof these projects. If youlookatcum impact,theyacknowledge LOSdecreasesatHawthorne/PCHandHawthorne/244th (aswell as the likelydecline atHawthorne/Valmonte. 4. From report: Using the HCMmethodology to determinelevels of service for thestudied intersectionsrevealed similar results in LOS. Intersection delaysincreased with each scenario and the Crenshaw Boulevard/PacificCoastHighway intersection furtherdeteriorated in LOSduring both peakhours of traffic.Also,the intersection of Rolling Hills Road/Crenshaw Boulevard decreasedin LOSto “E” during the A.M.peakhourundercumulativedevelopmentconditions. 5.

If yousupporttheirproposedampeakhour trafficof .3 vehper am peakhour,this impactwill be minimal.Butgivenamore realisticimpactof 1+ veh/unit(givendual-income householdsinresidence,asseeninthe Anzaapartments),the impactshere will be significant. 6. 74 trip endsduring ampeakhours,97 duringpmpeak.So 30% of the resident have jobs?

PerFig 17, 15% of projecttrafficwill goSouthonHawthone pastRollingHillsRoad.Where will that trafficbe goingand whatbasisfor determiningthatallocationwasused? 8. The ‘cumulative impact’portioniswhollyinadequate becauseitignoresprojectsinRedondo and Lomita(andothercities) thatimpact throughtrafficon PCH. Twosuch projectsare the condosat PCH/ProspectandPCH/PV Drive. Evenso, buttheir– inadequate –measure of cumulativeimpact,PCH/Hawthorne declinesto LOS D, Hawthorne/244th declinestoLOSD. Note that the claimis that cum delay improvesat PCH/VistaMontanafrom37.1 pmpeakhour to 37.2 in thisscenario.
