PUBLIC HEARING: PLANNING COMMISSION RECOMMENDATION RE APPLICATION OF CLEMENT CHEN AND ASSOCIATES FOR MODIFICATION OF PLANNED COMMUNITY DISTRICT 2637 TO EXPAND THE HOLIDAY INN HOTEL, 62 EL CAMINO REAL (Continued from 4/7/a6) (PLA 3-1) (CMR:427:6) Mayor Cobb said the applicant requested a deferral of the item. John Newman, Palo Alto Holiday Inn, requested a continuance on behalf of Clement Chen and Associates. Over the past several months they participated in hearings on the Downtown Study and represented to Council they would attempt to incorporate some of the findings into changes for the project addition. One of the areas concerned parking deficits. Clement Chen & Associates looked at areas adjacent to the property to possible create a parking structure to address the issues raised by Council, and it was brought to their attention there might be no better place than their own parking lot at the Palo Alto Holiday Inn. They were examining the possibility of committint a number of the current 330 spaces and/or future spaces Or City permit parking to benefit the City and to address and ameliorate the parking deficit. The issue would have to be reviewed with the City and also with the ultimate owner of the property, Stanford University. They were requesting additional time to identify those issues. 7 5 3 7 8/11/86 Mayor Cobb a,;ked how much time Clement Chen and Associates needed to complete the work. Mr. Newman said a week to two weeks. City Manager Bill Zaner said the meeting of Tuesday, September 2, 1986 would be the appropriate time for continuance of the item. MOTION: Mayor Cobb coved, seconded by Levy, to contlnue the item to the September 2, 1986 City Council meeting. MOTION PASSED unanimously, Sutorius, Woolley absent. 8. PUBLIC HEARING: PLANNING COMMISSION RECOMMENDATION RE AMENDMENTS TO THE ZONING ORDINANCE (Cont[n eu d from 7/21/86 (PLA 3-8) ._._ Planning Commissioner Jean McCown said the Planning Commission Minutes described their concerns. The proposed changes were adopted unanimously with the exception of two with one dissenting vote. Zoning Administrator Bob Brown had a correction to the ordinance. Page 4, first paragraph, last sentence should read: "Where the total parking provided is located in more than one location on a site, separated by differences in grade or by at least 3,0 meters (10 feet) of nonpavad area, each such area shall be considered a separate facility for the purpo<e of this requirement. Councilmember Renzel referred to the minimum requirements for landscaping for parking lots, and said there was an exemption from the paved area for required accessway, driveways, and pathways. She wondered if the exemption met the objective of a fair amount of green space. She understood an exemption from the perimeter landscaping if a driveway had to go through but queried an exemp- tion from the paving requirement. It almost seemed to be part of the building since it was a necessity to the building and was not a landscaping element. Mr. Brown said the point was well taken. The section of the ordi- nance was paralleled after the City's current ordinance and was probably the best rationale in .trying to maintain consistency. It could be included in computations of interior landscaping, etc.. Councilmember Renzel asked if such a change would conflict with anything else in the ordinance. Mr. Brown said no. There would be a change in the way staff reviewed plans, but not significantly. Councilmember ilinember Renzel clarified the landscaping would be considered part of the interior landscaping rather than part of the parking landscaping. 7 5 3 8 8/11/86 Mr. Brown clarified the landscaping would be included in the total for determination of interior landscaping. He suggested the Architectural Review Board (ARB) also might consider the ramifica- tions of the emange. Mayor Cobb declared the public hearing open. Linn Winterbotham, 819 Oregon Avenue, a member of the ARB, did not believe the change would make a significant difference. The ARB attempted to work with the adopted standards as to reasonable amounts of landscaping and impermeable surfaces. There was a con- cern about the way development was taking place in Palo Alto and the associated ecological impacts. The benefits of . landscaping were not seen for 3, 5, 10, 20 years, by which time those who made the decisions as far as what was proper were reflecting on what they did. It was important for the City to develop a standard applicable - to all projects in those areas with the greatest amount of environmental impact to the surroundiec neighborhoods. Buffers and parking areas needed to be ar.dressed. as far as minimum standards. The ARB tried to address general issues throughout the landscape areas, except for plant sizes, primarily to ensure greater compatibility in Palo Alto. Since joining the ARB, he was concerned the City really did not have qualified personnel to make decisions in regard to landscape items. Some sort of consistency throughout Palo Alto in interpretation of what buffers, front yards, and parking lots were should be app.'s is -i over time. The ARB believed it important to be included in the zoning ordinance because most of the items directly referenced existing require- ments in the ordinance. The items were intended as clarification, and hopefully it would be easier for staff, the applicants, and the ARB to review the projects. Councilmember Renzel asked whether excluding the accessways from the computation of the 25 percent landscaping on interior made any difference in how the ARB processed , the applications, or whether the extra increment of green would be noticed. Mr. Winterbotham clarified excluding the accesswayswould not make a significant difference as far as the amount of green, but pri- marily the amount of permeable surface to accept runoff to allow for a natural percolation. Some areas of paved surface added variety in the City, and including the .driveway would almost penalize someone who was trying to do something in terms of a small plaza, small sitting area, jogging path, etc. Councilmember Renzel referenced minimum plant size and asked whether the City required plants to grow to a certain height when *screen planting* was specified. 7 5 3 9 8/11/86 Mr. Winterbotham said the City did not require a certain height. He hoped the ARB looked at the quality and nature of the landscaping to achieve desired results. Staff did not want the ARB to get that specific. The City got a certain amount of protection but was not going the full way yet. Ccuncilmember Renzel believed a "screen" implied a shrub would grow more than three feet high, and asked if that was reviewed. Mr. Winterbotham it was reviewed. The requirements were not intended to be blanket for projects without allowing variation, which was where the ARB's judgment came into play. Many cities required specific types of plants for those areas. Mayor Cobb declared the public hearino closed. Councilmember Bechtel referred to a letter from C. William Spangler (on file in the City Clerk's office) concerning the defi- nition of "grade," and he preferred one of staff's alternates to the Planning Commission recommendation. She asked for comment. Mr. Brown said either definition was fine„ The City Attorney's. office believed the original wording as suggested by staff and approved by the Planning Commission was enforceable and under- standable, but Mr. Spangler's definition was just as valid. MOTION: Councilmember Klein moved, seconded by Fletcher, to adopt Planning Commission recommendations for amendments to the %oning Ordinance as follows: a) Calculation of daylight plane at common property line when grade differences occur between adjoining parcels; b) Definition of grade for determining height measurement; c) Clarification of RM-S height and coverage requirements when adjacent to RM-4; d) Clarification of the calculation of building height in the CC -2 zone; e) Addition to and clarification of landscaping requirements in parking facilities, other paved areas and landscaped screen and buffers; f) Definition of Gross Floor Area; g) Definition *f Projections and i 5 4 0 8/11/86 MOTION CONTINUED To amend Section 10 (2) to read, "Where the total Parking provided is in more . than one location on a site separated by a difference iu grade of..." ORDINANCE FOR FIRST READING entitled "ORDINANCE OF THE COOIIdiL OF THE CITY OF PALO ALTO AMENDING TITLE 18 (ZONING CODE) REGARDING DEFINITIONS OF GROSS FLOOR AREA, PROJECTIONS, GRADE, AND DAYLIGHT PLANE, RN -5 DISTRICT REGULATIONS, AND LANDSCAPING IN PARKING FACILITIES AND REQUIRED LANDSCAPED AREAS" Councilmember Klein. commended Mr. Winterbotham for his mammoth effort in helping produce the amendments which were an improvement for the City. Councilmember Fletcher expressed her gratitude for the set of amendments. For some time she was particularly interested in the landscaping for parking lots and the definition of gross floor area. The .City increasingly had uncovered space which was exempt from calculation of the floor area ratio ( FAR) and thus created bigger buildings. She was glad the matter was cleared up. Mayor Cobb added his thanks to Mr. Winterbothiam. The Council appreciated his work and that of the Planning Commissions. MOTION PASSED•,. unanimously, Sutorius, Woolley absent. 9, PUBLIC HEARING: PLANNING COMMISSION RECOMMENDATION RE APPLICATION OF MR. AND MRS. M,RTY WEINER FOR A PRELIMINARY PARC L _MAP, WITH EXCEPTIONS/ FOR PROPERTY LOCATED A1' 11 4 BYRON STREET (PLA 3-1) Mayor Cobb declared the public hearing open. Receiving no requests from the publi a to 5 peak he declared the public hearing closed. MOTION: Councilmember Bechtel moved, seconded by Klein, to adopt Planning Commission recommendations that the application for a preliminary parcel reap to combine two lots, and thus create a lot which remains substandard in width and area, will not have an adverse environmental impact and find that: 7 5 4 1 8/11/86 MOTION CONTINUED a) There are special circumstances or conditions affecting the property in that it is within a subdivision created before City zoning requirements established a minimum width of 60 feet and _ m nizJim area of 6,000 square feet for R-1 lots, but the property has functioned as a single 50 -foot wide, 5,750 square -foot lot for many years; b) The exceptions are necessary for the preservation and enjoyment of a substantial property right of the petitioner in that the owner should have the same rights to develop his property as the owners of neighboring parcels do; c) The granting of the exceptions will not be detrimental to the public welfare or ire j,.:rious to other property in the territory in that it will be larger than other lots created by the 1890 subdivision and will, in fact, be of benefit to the other property in the territory in that it will eliminate two very substandard lots; d) The granting of the exception will not violate the requirements, goals, policies, or spirit of the law in that the new parcel will be similar in size to other R-1 lots in Palo Alto; And recommend approval of the prei imioary parcel map. MOTION PASSED unanimously, Sutorius, Woolley absent. 10. PUBLIC HEARING: ORDERING WEED NUISANCE ABATED (PWK 5-2) (CMR:429 :6 ) Mayor Cobb said it Was the time and place set for Public Hearing on Resolution 6541 declaring weeds to be a nuisance. He asked the record to show that notice of the hearing had been given in the time, manner, and form provided for in Chapter 1808 of the Palo Alto Municipal Code. He asked if the City Clerk received any written objections. City Clerk Gloria Young said she had not. Mayor Cobb declared the public hearing open. Receiving no requests from the public to speak, he declared the public hearing closed. He asked the record to show that no persons appeared or filed written objections against the weed abatement proceedings, and any ,resolution . passed by Council on the matter would reflect the finding. NOTION: Oouncilmember Klein moved, seconded by Levy, to adopt the Resolution ordering the abatement of weeds. 01,8? i MOTION CONTINUED -RESOLUTION 6546 entitled "RESOLUTION OF THE COUNCIL OF THE CITY OF PALO ALTO ORDERING WEED NUISANCE ABATED" MOTION PASSED unanimously, Sutorius, Woolley absent. 11. GOLDEN TRIANGLE TASK FORCE MONTHLY STATUS REPORT (PRE 3) (CMR:433:6) - City Manager Bill Zaner said the Council packet included the first monthly etatue report -from the Golden Triangle Task Force. The Task F- rce requested each of the member City Councils and the Board of Supervisors agendize the item each month as the status report came out to discuss the report and take appropriate action. Mayor Cobb said he and Councilmember Klein attended the bi-weekly meeting of the Golden Triangle Task Force the previous Friday. There was a study session scheduled shortly, and the group was quite active. The Task Force appreciated that Palo Alto was a member of the Task Force. He suggested the item need not be agendized each month, but be an informational item in the packet. The item could be agendized as the Councilmembers wished, and brought forth for discussion on a regular basis. Councilmember Patitucci said many of the items before the Golden Triangle Task Force required action by the City Council. The first was the implementation of the .35 FAR. He asked if Council had already taken action. Mr. Zaner replied the action to implement the .35 FAR had not been taken; however, it was one of the items Council instructed staff to do. The City Attorney was drafting the necessary documents, and the item would be before Council on August 25, 1986. Mayor Cobb believed there would be ample opportunity for Council to discuss the actions. Council would follow the procedure out- lined but would agendize the item for discussion when necessary. Councilmember Klein said the first meeting as a member of the Golden Triangle Task Force was an education in hew difficult it would be to achieve some of the goals. The sr Erring between some of the member cities was obvious, and Pei() Alto's participation might be helpful in resolving some of the disputes. The task had to be done but would not be eaey: i.5 4 3 8/11/86 12. STATUS REPORT ON MOUNTAIN VIEW AMPHITHEATRE (Et -NV 5) (CM R : 4 3 6 : 6) ._. City Manager Bill Zaner said staff invited representatives from Bill Graham's organization to attend that evening's meeting. He showed transparencies which reflected where the problems occurred in Palo Alto and how the problems shifted areas. The Amphitheatre was located on Stierlin Road, two miles from Palo Alto's southern City limits. The first two concerts were held on June 29, 1986 and July 6, 1986, and no complaints were received. The first com- plaints were received about the Jeffrey Osborne concert on July 13, 1986. Between the hours of 8:30 p.m. and 11:30 p.m.-, about 75 complaints were received. The complaints were clustered between the Oregon Expressway and the creek, close to the freeway. The Stevie Nicks concert was on Monday, July 14, 1986, and the City received 84 complaints between 6:15 p.m. and 11:45 p.m., most of which were concentrated by the Oregon Expressway, out toward the creek, and clustered in toward the freeway. One or two complaints were received around Loma Verde and Colorado. A substantial amount of work was done on Thursday, July 17, 1986, by the Shoreline Amphitheatre to adjust the volume, and change the angle of the speakers for the Beach Boys concert, and Palo Alto received no complaints. The Julian Lennon concert was on July 26`r 1986, and the City received no complaints. For the Ronnie Deo concert on July 27, 1986, the City received two complaints. Staff believed the problem was under control. On August 2,, 1986, the Jimmy Buffet concert, the City received 135 complaints between the hours of 8:30 p.m. and 11:10 p.m. Many of the complaints were complaints south of the Oregon Expressway and for the first time, complaints were clustered around Colorado, Lorna Verde with a large number north of the Oregon Expressway and a couple in Barron Park. On August 5, 1986, the Bob Dylan concert, there were 90 complaints centered above Embarcadero, The City did sound tests using its own equipment and readings were taken on each night complaints were received. After recalibrating the equipment to ensure accuracy, the City was convinced the sound meters did not register any increase over the background noise in the neighborhoods in which the testing was done. The music was audible but did not register on the machines. The City received cooperation from both the Mountain View City staff and Mr. Graham's organization. Palo Alto was kept up to date on what was being done. Speaker loca- tions, directions, and volumes were changed, and many experiments were done. Mr. Scher of Bill Graham Pcesents and his consultant could give more information. While the location of the complaints stayed in the northern part of the City, they tended to spread. Between then and September 22, 1986, which marked the end of the current scheduled concert season, 13 concerts remained. Mayor Cobb welcomed Jim Zesch, a Councilmember from Mountain View, who was present to hear Palo Alto's concerns. - 7 5 4 _4 8/11/86 Councilmember Ren zel asked about the City's course of relief if the problems could not be resolved. Mr. Zaner said staff was looking for a "technical solution" to the acoustical problem. The first course was to work with the City of Mountain View and the developers who re required to solve the problem. The City of Mountain View was adamant that the problem be solved. The operators were spending a lot of time and money on consultant assistance to solve the problem. Councilmember Patitucci asked about the level of complaints, the types of sound causing the complaints and whether Mountain View had the same problems. Mr. Zaner said the problem appeared to only be in Palo Alto. Mountain View received a few complaints, but nothing like Palo Alto. Palo Alto's complaints varied. He deferred to Mr. Scher for the acoustical information. William T. Leaser, 964 Colonial Lane, believed the Amphitheatre was a nice addition to the area, but he was concerned about the noise problem. Danny Scher, Vice President of Special Events, Bill Graham Presents, said the music appeared to affect the quietest neighbor- hoods, but if the sound was turned off, the sound meter would not go down. They wanted to solve the problem, but it was not as simple .as turning the sound down. On the nights when there were no complaints, the concerts were the loudest. The most complaints were received on nights of the quietest concerts. He referred to "inversion .layers, t' which were layers of warm air over cooler air. It acted almost as a mirror and bounced the sound back. The higher the inversion layer, the greater the angle which meant the sound went farther away from the source bypassing everything between the point of origination and where it ultimately ended up. Generally sound went up, and by the time it came down, it was like a meteorite and was totally dissipated. He wished turning the sound down one decibel seem to work that way. and somehow the music neighboring community. people to call so they problems seemed to be then returned the next concert season would October. would cause a domino effect, but it did not It was a phenomenon they never dealt with, needed to be less than the ambient in a It would take time, and he encouraged knew where the sound was coming from. The solved one night in one neighborhood, and night in another neighborhood.: The annual be from mid -April through the end of Councilmember Patitucci asked who decided how loud music would be for a particular performance. 7 5 4 5 8/11/86 Mr.. Scher said the artist's sound technician decided on the volume, and every artist had his or her own sound system. The Amphitheatre turned off its lawn system to see whether it was the source of the problems, but more complaints were received on that ►sight. They did not know whether the problem was coming from an acoustical property of the tent. People tended to absorb sound and they did not know whether less people caused the sound to seem louder. If sound traveled by the wind, there would be complaints in Sunnyvale. It was a new situation and being ambient or turning down the source was not acceptable. They did not know how to rectify the problem. He called the National Weather Service in Redwood City to ascertain the height of the :inversion layer and was told it was 1,300 feet. He tried to find a correlation of the inversion layer and the loudness of the music inside the Amphitheatre to make the angle greater so by the time the music returned to earth it totally dissipated. However, inversion layers were measured from the Oakland Airport. Now he was trying to fir\d a correlation between the sound inside the amphitheatre and an inversion layer over the -Oakland Airport. Councilmember Patitucci asked about changing the times of the performances. Mr. Scher said it was tried in another city, but there were more hate letters from people who had to leave work to hear perfor- mances or could not attend at all. They were also dealing with the public who finally did not have to drive to San Francisco or Oakland to see what they believed to be world class entertain- ment. Councilmember Patitucci asked about East Palo Alto. Mr. Scher said there was one complaint. Mayor Cobb referred to the artist's control of the on-stage sound system, and he asked whether the Amphitheatre had any control. Mr. Scher said generally yes, but the correlation between how loud the music was on stage and how it affected Palo Alto was not yet found. The first step was to turn the music down at the source, which was done, and the Amphitheatre was also monitoring the top of the lawn seating to find the critical point of sound com- plaints. . If complaints were not going to be non-existent, they preferred they be the exception and not the rule. 1 5 4 6 8/11/86 Joe 0. Louis, Paoletti-Lewitz Associates, Inc., acoustical con- sultants in San Francisco, said measurements were taken to quan- tify the magnitude of noise levels in the community generated by the music in the Amphitheatre, which was typical with the poten- tial for noise impacts so that sufficient mitigation could be determined. Noise impacts were typically assessed with respect to the difference in sound level between the intruding noise and the existing ambient. The concert sound in Palo Alto was so close to the ambient sound level it was not measurable with their environ- mental instrumentation, but under certain conditions, it could be heard. When the music could not be heard, it was partly due to certain meteorlogical phenomena, such as wind, humidity, and thermal effects which tended to either support or suppress the sound as it propagated away from the Amphitheatre and into the. community. The effects were difficult to quantify because of weather variables and the difficulty with precisely identifying the location and magnitude of the mcteorlogical phenomena which constantly changed. When the conditions were right, concert sounds were sometimes heard up to five miles away, but they were not measurable on Me sound level meter. The human ear selec- tively detected different frequency components of different noises, and even when two sounds were close in terms of decibel level, they could still be differentiated by the ear. In Palo Alto, the ambient noise level was comprised primarily of trans- portation noises such as cars, trucks, buses and railroad. There was some contribution from wind in the trees and distant aircraft. The day and night ambient sound levels were, low. Superimposed on the ambient were relatively short duration transient events such as aircraft , crickets, barking dogs, which were clearly discern- able above the ambient because their sound levels were higher than the ambient and the frequency characteristic was different from the contributors to the general overall ambient. Even if the other transient events were close to the ambient sound levels, they would still be heard because the sound.. had a different fre- quency spectrum. The concert sounds were discernable not because they were loud or above the existing ambient, but because the character of the sound was different from the ambient. With respect to Shoreline and what the Amphitheatre did to address noise control such as the .location of the facility and the posi- tion of the loud speakers, berms and barriers which surrounded the Amphithreater all contributed to the reduction of noise levels in the surrounding communities. Once an intruding sound level was reduced to the ambient and once it could not be measured any longer, there was no way to calculate how much more reduction would be necessary to make the sound totally indiscernable to even the most critical observer who . carefully listened for a specific sound. As environmental noise specialists, they were not used to dealing with noise problems where the intruding sounds were so low as to be immeasurable above the ambient. 7 5 4 7 8/11/86 Mayor Cobb asked if selectively using something like graphic equalizers, rather than just turning the volume down, might modu- late some of the offending sounds. He also asked whether it was possible to ascertain the inversion layer in advance of a concert to make appropriate modifications. Mr. Louis said graphic equalizers could be used because higher frequencies had shorter wave lengths and were absorbed more and were more directional. The low frequencies rolled over the bar- riers. Regarding inversion layers, the decibel level or the amount of decibel increase or decrease created by the meteorlogi- cal phenomena was difficult to pin down. It was not a precise science because there were so many variables and weather patterns constantly changed. Keeping track of the information would be important, however, in relating to the actual sound levels, Councilmember Levy asked what was specifically being done at each concert. Mr. Scher said they were currently gathering data on the inversion layer as provided by the weather service. An inversion layer was measured by going to the Oakland Airport and putting a balloon in the air with transmitters, which transmitted barometric pressures, temperature, humidity, which burst at some point. Out of the information came an inversion layer --but not necessarily an inversion layer over Palo Alto. On a per show night basis, they monitored the weather as it was in Palo Alto, the inversion layer as they were told, they had people at the sound board measuring the loudneas, there were people at the top of the lawn seating measuring the sound, and there were people on the eai anaa.,as waiting for calls. Shoreline had its own map, and every show had different color push pins. He expected to see a lot of integrated colors, but it turned out to be spots of colors with some overlap. The music could be turned down inside, but it did not mean it could not be heard, but other nights, it could not be heard. The higher the inversion layer, the less likely Palo Alto would hear the music. He understood the inversion layer rose later in the year. If they could_ find out on a per show basis that they would have a low inversion layer, they would go to the artist and tell them to turn down the music as long as the people inside the Amphitheatre were not inconvenienced. He was trying to find the middle ground where the people inside and outside were happy. He hoped the next time the sound level worked it would be based on some scientific data. Councilmember Levy asked whether it was possible to do any weather studies at the Palo Alto .Airport or someplace ;closer to home, and whether anything could be done with physical construction. 7 5 4 8/11/86 Mr. Scher said in a City where they had a similar problem they built a physical, tall wall that stopped the sound. Shoreline's windwall--which was a very high wall with mesh material like tennis netting --was built for two reasons: as a wind mitigating device, and for aesthetics. They could not build a structure because of the nature of the soil and landfill which would con- tinue to settle indefinitely. The wind would be more adverse inside if they replaced the tennis -netting material with plywood. The tennis fabric totally dissipated the wind off the bay. He did not believe a wall was the answer but hoped experimenting with placement, distribution, and angles of the speakers, coupled with knowledge of the inversion layer and sound at the monitor board would solve the problem. Councilmember Bechtel encouraged efforts to solve the problem. The idea that such sound could occur a couple of times a week, year after year would be irritating to people. Mr. Zesch said the Amphitheatre took the complaints seriously, and the City of Mountain View was looking over their shoulder. Mayor Cobb appreciated the efforts of the people from the Amphitheatre and encouraged them to try to find a solution. 2. SANTA CLARA COUNTY TRAFFIC AUTHORITY MEASURE A PROGRAM -- STRATEGIC PLAN PLA PRE -2-6) (CMR:435;6) City Manager Bill Zaner said Mr. Will Kempton, the Executive Director for the Santa Clara County Traffic Authority, was present along with their consultant. A copy of the proposed program for the Strategic Plan that the Authority contemplated adopting was included in Council's packet. Mr. Kempton said the Strategic Plan was really the implementation plan for the Measure "A" program and was an important document. They were present that evening to alert Council to the content and format of the docvmer. and to solicit Council's continued involve- ment. They might have read in the newspapers of problems cropping up with the Measure "A" program in terms of the revenues available for completion of the work to be done. In January, it became apparent that the original revenue projections for the Measure "A" program were off and that the Santa Clara County Traffic Authority would have to adjust them downward. Santa Clara County had tradi- tionally experienced a high growth rate in sales tax revenues which reflected .the extremely solid, strong, progression in the County. Now the sales tax: growth rate was declining closer to the average State wide, which resulted in the need to revise the rev- enues available for the program. The Traffic Authority elected to do . that through four separate scenarios: To build a program based on essentially no growth in revenues, low growth, moderate growth, and on the traditional high growth rate. The biggest impact was 7 5 4 9 8/11/86 the increase in the cost of building what they originally intended to build. The Measure "A" program was restricted to three routes. in the County: Route 101, Route 237, and Route ;?5. The routes were owned and operated by the State of California through the Department of Transportation. The Department had specific plans for what they would like to see built in the corridors over the next 20 to 30 years, referred to as the Caltrans ultimate plan. The ;Authority had to pay attention to the plan because the state owned the facilities. With the Measure "A" revenues, the Authority was finding a way to get many of the improvements built earlier. When the Measure "A" program was initially put together, the estimate of costs for the Measure "A" improvements was approximately $700 million in current dollars. Caltrans' ultimate plans approached $1.3 billion in current dollar value. Almost 50 percent of the needs would go unfunded according to Caltrans' estimate of what needed to be done. If those dollars were related back to what was originally promised to the voters in 1984 during the campaign, they were looking at a current dollar value of $1 billion to $1.1 billion in work needing to be done, and they were looking at a substantially lower amount of revenues. The problem facing the Traffic Authority in the Strategic Plan process was determining which work was of the highest priority and the best way to apply the funds. They were approaching the problem through the development of five policy guidelines dealing with how the money should be applied overall. The next stage of the process was looking at several scenarios as to how the money was applied, and they had difficulty because the cost figures currently avail -- able from the Department of Transportation were not solid. Admittedly, the Department of Transportation managed well by pro- gram. They generally did not concentrate on project specific information. Councilmember Klein asked why the proposed projects went from $700 million to $1 billion in a period of virtually no inflation. Mr. Kempton said the Traffic Authority believed the numbers were not good to begin with. There had been some increase in scope. Over the course of the two years as Caltrans became more involved in the project, they saw those kinds of increases, e.g., the Lafayette/Great America interchange was originally proposed at $29 million, and the current price was $86 million. The Traffic Authority agreed the credibility of the Transportation Department in making those estimates was up for discussion. Members of the Traffic Authority felt a deep sense of responsibility and wanted to apply the available dollars in the best possible way. One of the reasons the Traffic . Authority retained Bechtel Civil and Mineral>s Incorporated to help manage the program was to get to the root of those numbers, and to control and manage against those numbers so they did not see any additional cost increases. Councilmember Klein said with such an increase in the scope of en interchange somebody was either eestraordinarily inefficient or had misconstrued the facts. l th1,5811 Mr, Kempton said he would be happy to show what was originally planned in terms of a clover -leaf interchange against what Caltrans currently proposed with flyovers, concrete structures, director connectors, and direct speed connectors going in all directions. The difference was incredible, and the difference in cost was evident. He believed it assured they would not be able to build the interchange. He came in September of the previous year and found no indication that anybody was trying mislead anybody in the program. Clearly, the people who put together the Measure "A" program were sincere in expecting the funds raised through the Measure "A" tax would be sufficient to fund the work promised to the voters in 1984. Councilmember Fletcher did not remember part of the proposal of the Measure "A" campaign included the widening of the existing Route 85 to six lanes, or the construction of the 101/880 interchange and the widening of ramps of the north connection from 85 to Route 101. She asked if those were add-ons from what was proposed in the campaign. Mr. Kempton said the only add-on of the group was the. 101/880 interchange. The interchange was also . not included in the numbers he recited and was a costly piece of the Caltrans ultimate plans for the region. Councilmember Fletcher as% _c about the Route 237 completion to eight lanes from Maude Avenue to Route 237/880 interchange. Mr. Kempton said the Traffic Authority said ... =e Route 237 comple- tion to eight lanes was not included in the original scope of the program. Six lanes were all that was committed to for Route 237. The eight lanes were part of Caltrans' ultimate plans. Councilmember Fletcher asked for a figure for the 101/280 interchange. Mr. Kempton said the cost was about $150 million for the inter- change alone and substantially more for the approach .improvements Caltrans proposed in terms of changing the grade of the facility. Mayor Cobb about the City's protection against continued cost growth. Obviously the system could not keep growing at that .rate or nothing would get built. Mr. Kempton said it was something the Traffic Authority had to deal with. Caltrans was not in tine to menag ing by specific project. The Traffic Authority would be working with the Department of Transportation. The key problem in terms of managing the program was coming to grips with the ability to 7 5 5 1 8/11/86 provide the accountability so necessary to the voters and to the citizens of the County. The only way to do that was to get the kind of cost information that was not readily available through the Department of Transportation.- Caltrans was good about recognizing the problem and had opened the doors to the Traffic Authority. Councilmember Renzel asked if all Measure " `," improvements were intended to address existing traffic problems or were they also looking \to the future. If so, were some of the improvements apt to be impacted or scaled down as a result of the work of the Golden Triangle Task Force. Mr. Kempton replied the improvements were geared to the future. The Traffic Authority was certainly looking to help resolve future traffic problems. On the other hand, they were playing a game of *catch up" to some degree, and perhaps in a few years as traffic increased they might see continuing problems. He believed the Golden Triangle Task Force had initially adopted an approach to the Measure "A" program of assuming that Route 237 would be fixed, that Route 101 would be fixed, and there would be a Route 85, not considering there might be insufficient resources to do all the work necessary on those routes. The Traffic Authority was making the rounds to communicate to people what was happening with the Measure "A" program. Councilmember Patitucci clarified Measure "A" was passed based on estimates Caltrans made for the various routes covered by the ten -years' worth of one-half cent sales tax. Caltrans reestimated to about $1.5 billion instead of $750 million. Mr. Kempton said $1.5 billion related to what Caltrans ultimately wished to do in all the routes, not to the specific Measure "A" projects which was $1.1 billion. Part of the problem was that Caltrans did not estimate correctly, but the other part was the costs legitimately went up as Caltrans got deeper into the projects and found things that worked better. It was a combination of the two. Councilmember Patitucci clarified the projected revenue might be lower than originally projected because of a slower growth rate in sales tax. Even though there was a comfortable margin to do the projects at the price originally budgeted, they now might not have enough dollars to do all the projects at the current estimate. He hoped they were not, returning to the voters to ask for more money. Mr. Kempton said Councilmember Patitucci was correct, and returning to the voters was not in the plan. 7.5 5 2 8/11/86 Councilmember Patitucci asked about returning to Caltrans and ungoldplating the process. His experience was Caltrans wanted permanent monuments and ultimate plans. Mr. Kempton said returning to Caltrans was the heart of the Strategic Plan process. The Authority must look specifically at the plans to try to eliminate some of the goldplating as they pro- ceeded through the entire program. There would . be money savings from that. Further, they had to refocus their efforts in terms of leveraging the highway improvement dollars to provide an addi- tional inflow of state and federal resources into the County to help make up for some of the shortfall. For example, the 237/880 interchange was a prime candidate for state and federal funding. Referring to a history of the cost estimates: In July, 1984 the original estimates were made on limited information. There had been four iterations of estimates from the Department of Transportation since then and each went up. It was key they began to develop the kinds of watchdogging controls necessary to hold the cost for the program down as quickly as possible. The draft policy guidelines included five basic statements, the first being an increase of highway capacity on the Measure "A" routes with some subsets. The Traffic Authority was looking to provide reasonable and cost-effective mitigation measures. They proposed a high degree of mitigation for the 'program which would take dol- lars and reduce some capital improvements. They wanted to accelerate the implementation of the program as much as possible to save inflation dollars. To that end, they recently completed a successful, sale of $2 million worth of bonds which provided upfront capital money. They wanted to integrate improvements with the State Highway program, which was an effective way to bring moreore dol 1 arc int,N #�he program Nnd to has p fill tjA Cis Measure "A" WVi obi �. ei 44.V b4�er �s v�k M�ea �. J` _ was not able to finance, and they were also looking to optimize the application of available resources. They were looking at opportunities for joint development with some of the right-of-way they were purchasing and for additional opportunities to purchase federal apportionment. They would approach the Department of Transportation about paying for tne engineering costs for the program which over a ten year period would save in excess of $100 million. The Traffic Authority was making presentations to many interested groups and to . all City Councils in the County. The Traffic Authority would hold an additional work session on September 3, 1986, and adopt a. draft plan on September 15, 1986, which would be circulated to all the Cities and to the County for comment. Public meetings would then be held` to obtain as much input as possible prior to ' adopting a final Strategic Plan in December, 1986. The final Strategic Plan would be a flexible document. He saw the Traffic Authority adopting a range of scenarios based on the revenue scenarios adopted earlier in the year. 7 5 5 3 8/11/86 Mayor Cobb was concerned about the cost growth which could not be allowed to continue. Councilmember Fletcher mentioned Council received the agendas after the Traffic Authority meetings took place. Mr.. Kempton said the Traffic Authority had received similar com- p.•.eints and was looking into the matter. Councilmember Fletcher wondered if she might transmit a sense -of - the -Council position to the Transportation Commission which had the item on its agenda in two days. She clarified the position as eliminating the goldplating and not returning for more tax money. REQUEST OF COUNCILMEMBER FLETCHER RE USE OF 1/2 CENT SALES TAX TO FUND CONSTRUCTION OF EXPRESSWAY COMMUTER LANES (PLA 4/PRE 3-2-6) Councilmember Fletcher referred to funding for the expressway high occupancy vehicle (HOV) lanes, and said the first proposal by the Manufacturing Group was that the County adopt a policy of creating a network of commute lanes. Commute. lanes were defined as being used by multi -occupant vehicles including automobiles with two or more people. The proposal mentioned using the transit tax to fund the HOV lanes as well as lit ' ted Federal Aid Urban (FAU) money. At that time no decision was made about the funding, but the policy was adopted to create a network of HOV lanes. The authori- zation to use ..transit funds was proposed to be on the November ballot when the transit tax would be before the voters for reaffirmation. The original draft from County Council gave the but wasnot by choice of yes or no on the specific 1.sS?:�, adopted ...j the supervisors. The wording of the new plan (on file in the City Clerk's office) made the whole ballot measure very comprehensive. While the wording did not specifically state commute lanes would be. funded by the transit `, tax, since there were no other funds available except for some FAU funds, it was evident where the money would core from. She referred to a report from the Finance Committee to the Transportation 2000 (T-2000) Steering Committee (on file in the City Clerk's office). The committee met without public announcement and the meetings were closed. Their proposal to recommend to the Board of Supervisors that transit funds be used for the construction of the commute lanes would go to the Transportation Commission on Wednesday for a vote. She asked for guidance from Council on whether it was appropriate to use transit tax funds to construct commuter lanes. Councilmember Renzel said there was news regularly that the Transportation Commission would have trouble financing the Peninsula rail service in a few more years. The rail service was a permanent transit facility heavily used by Palo Altans and 7 5 5 4 8/11/86 people between San Jose and San Francisco. While the rail service did not make a profit, it kept many cars off the road and provided an efficient transportation service which would become more valuable as gridlock advanced on the freeways. The HOV lanes were still experimental and were likely to become ordinary lanes of the freeway in the future. They all supported the transit tax with the idea of keeping the SP available, increasing bus service, and possible BART extensions. It was dangerous to extend the transit definition to freeway lanes. She encouraged giving Councilmember Fletcher strong support to oppose the diversion of transit funds. Councilmember Klein was loath a take issue on a complex subject without more time to study it, and he did not see Council had the obligation to do so. Councilmember Fletcher was given the authority to vote the way she saw things until Council directed otherwise. He was sympathetic to many of the comments and to HOV lanes. He understood from data presented that one of the best bets to reduce the congestion on the freeways was HOV lanes. He preferred to see the matter continued. Councilmember • Bechtel concurred. .As a member of the Transportation Commission, Councilmember Fletcher had an obliga- tion to represent herself and did not .necessarily represent all of Palo Alto or the City Council, and also had the ammunition of Council's vote the previous fall expressing concern about using transit money for HOV lanes. She shared some of Councilmember Klein's concerns. People had to feel they could get to work as fast or faster on public transportation in order to be attracted out of their cars. and people would leave their cars if lanes could be set aside for exclusive bus use. She believed the matter could be returned to Council for it to take a position before the November election. Mayor Cobb agreed with the comments of Councilmembers Klein and Bechtel. He urged Councilmember Fletcher to inform the Transportation Commission that Council took the matte seriously, but wanted to have the information and time to s; -e.-; uhe issue in order to make knowledgeable decisions.
