6.1 E Page 6 Mr. Peter Vorarnetsonfi IVlay !4, 2009 Page 2 Modeling the ferry termina!dicta�es that TJKM create a special generator procedure in the model at the TAZ for the proposed terminaf site. Review and analysis af ferry ridership forecasts and fand-side vehicle access/oCCUpancylparking data provided by the Water Emergency Transit Agency, and communlCation with City staff regarding the resu�tfng peak hvur trip generat�on assumptfons to be used in the mode[ is lncluded in th�s task. TJKM proposes a fee of$42,75�to perform the expanded scope of work required to add these major transit infrasCruceure improvements to the traffic model for the new G��eral Plan alte�-nat3ves. In addition, TjKM anticipates that the following expanded tasks,which are also beyond the scope of work and budget of our original contract, will be needed to provide the mode�ing serv€ces the City requires for both the General Plan and Indiv{dua! development tra#fic stud�es: Preparation of Transportation Network Assumptians for Cumulative Model � The Cumulathre General Plan scenarto wi�! include development o�'the DMB Redwood City Saltworks (Saltworks) project City sta.#f has forwarded TJKM some documents submltted by the applicant,which include a"Saltworks Speci�c P�an Cumu[ative Project Description" �one paragraph of text), and the following materials(dated March 17, 2009}: conceptua!site plan, on-slte roadway cross-sections,and narrative descriptions of various transportation network cor�nections, services, and trip reduction measures. City sta#f is pro�iding the land use data by TAZ#or input to the model. Howeve�-,TJKM must still perform sign'rficant review and analysis of the transportation network information provided to prepare the network assumptions and trip reduction factars to be used in the Cumuiativ�model. T,jKM will aiso create a special generator in the model at tt�e TAZ#or the recreation field area proposed on the project site. These tasks are beyond the scope of work in our orlginal contract. At thls time, pending discussion with City staff to further define the transportation network assumptions, estimating the scope and budget for this task is diff#cult. TJKM proposes to perform this particular Cask by charging otar standard billing rates on a time-and-materials basis with a not- to-exceed fimit of$8,500 unless the City provides prior writter�authorization for any additionai charges. Continuing"On-Ca[t" Mode!Support Services We understand that the City is likeiy to require use of the traff�c modei for future traffic impact stud�es of Iarge development projects,as is the case wit#�the Stanford Campus Extension EIR study that Hexagon is currently performing, Under our original contract,TJKM will provide a copy of the traf�'ic model to other parties with written authoriza.tion fi om the City. However,we anticipate occasions when those parties wili request additional informatlon and support for the model from TJKM similar to our recent interactions with Hexagon regarding the Stanford project as mer�tioned above,a level of support which was not included in the scope o#our original contract. Additionally, TJKM responses to detailed inquiries or requests from City staff a- consultants that go beyond explanation or clari�cation of model assumptions and the forecasts produced, such as those invo�ing queries or manipulation of model data frles or generation of new data,are additional work outside our original scope. TJKM proposes to provide this continuing"on-caI[" model support service as needed o�a task order basis. B�#ore responding to any detailed inquiry or request for mode[support,TJKM would provide the City with an estimate of our anticipated charges,and we would proceed only if the Gity gives us approvaE. As an initial budget for these on-call services to be included in the requested contract amendmerit,TjKM suggests not-to-exceed limit of$25,�0.
