The regional location of the project site is shown in Figure 1 and the local setting of the proposed project is shown in Figure 2. The site is bounded by Airport Boulevard to the north, a lagoon area to the south, Anza Airport Parking to the east, and vacant land to the west. 1.2 PROJECT CHARACTERISTICS AND OBJECTIVES The proposed project, Da�s Inn Motel, Airport Boulevard, consists of a motel developmen�t with an appurtenant coffee shop, small game room, and office area in a separate bi�ilding from the motel room structure. A pool and level lawn area would also be provided at the project site for patron� of the motel. The preliminary site plan for the proposed project is shown in Figure 3. The principal structure of the development would be a five story building, approxi- mately 46 feet in height, containing 214 guest rooms. The separate structure in front of the motel would be a one story building, approximately 15 feet in height, containing a coffee shop with approximately 43 seats. The coffee shop and gift shop, and game room would be provided as a convenience to the motel �uests. Gaso- line service would be provided to automobiles through on site retail pump facilities. A total of 214 parking spaces would be provided around the motel building. Of these spaces, 39 would be designated for compact cars, while the rest would be full sized parking spaces. The motel building footprint, including the separate motel office, would cover approximately 15 percent of the sit� area. Landscaped areas, including a five foot green strip around the property and other green and planted areas, would cover approximately 22 percent of the site. The pool area to the rear of motel building would cover about three percent of the site. The remaining 60 percent of the project site would be utilized as parking. The appraised value of the project has been estimated by the applicant to be $6,250,000. , U � � � � � � � U � � � � � �J � � G � � • � � N FIGURE 1.

The 2.89 acre site is currently undeveloped and sparsely covered with vegetation. Office,and commercial usage predominate in the A.nza area, with warehousing, dist'ribution services, light manufacturing, office and hotel/motel being the largest uses (Blaxney, 1977). The project site abuts Airport Road directly across from the Purdy Office Building. To the north of the Purdy Office Building are the La Baie restaurant, Southern Pacific com- mun�cations building, and San Mateo County Convention and Visitors Bureau. To the south is a vacant parcel. to the east of the site. The Anza Airp�rt park and fly facility lies The Waterfront Element of the City of Burlingame General Plan was adopted in 1969. The plan sets forth objectives for the Waterfront Area, an implementation plan, and some specific criteria for waterfront developments. The objectives that apply to the proposed project are: (.1) increase of public access to the shoreline and Bay, (2).provision of sites for commercial uses that involve use of waterfront opportunities by the public, and (3) improvement of visual qual- ities of the shoreline. One way to achieve the above ohjectives would be the development of a Specific Plan for the Waterfront Area. A Specific Plan is defined by the California Administrative Code as a portion of the General Plan that precisely locates various types of uses within a specific area. Although a Specific Plan has not yet been adopted for th.e area, the Burlingame City Council on February 7, 1979 approved a plan for the Anza Area of the waterfront that designates the project site for hotel or motel development. Design criteria specifically mentioned in the Waterfront Element call for avoidance of: (1) long unbroken shoreline dikes that cut off ground level views, (2) overhead utility lines, and (3) long expanses of buildings parallel to the shore. The design criteria encourage clustering of buildings, varying the heights of buildings, locating buildings to provide opportunities for visual corridors from local streets and other buildings to the Bay, and using appro- priate trees, shrubbery, and ground cover as part of the total landscape. �� � �J � � L.l � � l.J � � U l_.! � t' J � � �i Zoning Ordinance. The existing zoning designation is Waterfront Co�nercial .(C-4). The City of Burlingame established the Waterfront Commercial District for "land uses, buildings, and structures that will benefit from their prox- imity to the open water areas of San Francisco Bay and will be beneficial to the public use of this irreplaceable natural resource". The city asserts that ". .. economic as well as aesthetic advantages accure to the land, the occupants, and the public from the required controls and regulations," (City of Burlingame Zoning Ordinance, 1977). San Francisco Bay Conservation and Development Commission. The San Francisco Say Conservation and Development Commission (BCDC), created by the McAteer Petris Act in 1965, has regulatory authority over development and use of the Bay and its shoreline. Generally the issues of interest to the BCDC (on any projects in their jurisdiction) are bay fill, uses on bay fill, and public access within the 100 foot shoreline band. The San Francisco Bay Plan and the supplement document provide specific environmental and land use studies and develop conclusions and policies concerning use of the Bay environs. Regula- tions supplementing and interpreting both the McAteer Petris Act and the Bay Plan have been promulgated and provide permitting procedures for BCDC authori- ties over Bay uses and development. The BCDC is assembling a Bay Recreation Plan and is currently compiling an inventory of public recreation facilities along the whole of the bay shoreline. The 100 foot BCDC shoreline band is shDwn in Figure 4. IMPACTS. The construction of the proposed motel would eliminate approximately 2.9 acres cf open space of marginal wildlife habitat (see Biology). A motel usage would be in conformance with both the Waterfront Element and the specific recommendations made by the Burlingame City Council. As proposed, a publicly patronized commercial enterprise with a water oriented design would be consistent with the desires of the City of Burlingame for continuing public, water oriented projects in this area. The project would not provide recreation for the general , public, but would provide a pool for its patrons. Zoning Ordinan�e. A motel use is permitted by the C-4 (Waterfront Commercial) zoning designation, and therefore would not require any variances for type of use. : � r�--� [�) �� �-� ��� ��' �� G--� c�- � c�.� C� � ��i r� �� �-� �� c� C� � - , N FIGURE 4.

(A variance would be needed if setbacks were less than 30 feet from the curb.) No special permit would be needed relative to the city's criterion of building height exceeding 50 feet or floor area ratio (FAR) exceeding 1.0. The building, as proposed, would be five stories (slightly under 50 feet) in height. The proposed building coverage would be 17 percent of the total lot. The FAR would be approximately 0.85. Since the FAR would not exceed the prescribed 1.0 limit, no special permit would be required for coverage. A special permit will be required since the project is not in conformance with the Anza Area Design Guidelines (City Code 41.21.025f). Section 2.4.of this report discusses the Design Guidelines. San Francisco Bay Conservation and Development Commission. The western tip of the project site is situated within the BCDC 100 foot shoreline band as shown in Figure 4.� Most uf this area is set aside for public access as a land- scaped easement. A small proportion of the band would be used for approxi- mately 16 vehicle parking spaces and would thus be paved with asphalt. A BCDC permit would be required for this usage. The primary review criteria of BCDC within the 100 foot band are public access, which is discussed in Sec- tion 2.4, and design/visual factors. MITIGATION MEASURES. The following mitigation measure is suggested to mini- mize the planning impact of the project. • Provide a connection across the southern edge of the property for lagoon access by pedestrians from Bayside Boulevard. E:3 � � 2.2 TRAFFIC AND TRANSPORTATION ( �� � EXISTING SETTING. Present access to the project site is via Airport Boule- vard. Airport Boulevard is a four lane divided arterial with curbs and a landscaped center median. The roadway narrows to two lanes in the vicinity of the intersections with Bayshore H.ighway to the west and Coyote Point Drive to the east. The center median is broken at numerous locations to allow left turns with some protected left turn lanes. Airport Boulevard provides con- nection to U.S. Highway 101� and Bayshore Highway at the Broadway interchange to the north and at the Peninsula Avenue interchange to the south. These road- ways are shown in Figure 2. Traffic volumes along Airport Boulevard are presently well below the capacity of this roadway. Large tracts of land along Airport Boulevard, also known as Anza area, are either undeveloped or serving low intensity usage. However. � traffic delays do occur during the peak traffic period (4:30 to 5:30 p.m.) at the principal local intersections of Airport Boulevard. The intersections of � � � � �I � � � �` Airport Boulevard with Bayshore Highway and Coyote Point Drive represent the most important local traffic constraints on development at the project site. The intersection of Bayshore Highway with the U.S. Highway 101 northbound on ramp and Broadway overcrossing is also important to such development. Level of service analysis has been performed on these three important inter- sections indicated. This analysis indicates the present degree of congestion which occurs at these locations during the peak. traffic period. A descrip- tion of the various levels of service is presented in Table l. The results of the level of service analysis at the major intersections are presented in Table 2. The levels of service shown in Table 2 indicate that traffic flow is quite good at the intersections indicated. Some delays do occur at the intersection of Airport Boulevard and Coyote Point Drive, but these are the result of right of way assignments and not inadequate capacity. The City of Burlingame is presentJ_y studying the entire area along Airport Boulevard in order to allow development of this area which is compatible � U 11 � �f i � � � � � � � �.J � � � � i TABLE 1.

As a part of this program, a methodology has been prepared which allows for a determination of impact on the critical intersections for various developments in the area (Drachman, 1979). This methodology called the Drachman Traffic Study, has been incor- porated into the discussion of traffic impacts of the proposed project. In- formation concerning the number of lodging units per acre of site land was included in this analysis. � U.S. Highway 101 through th'e City of Burlingame carries peak hour traffic volumes which are near the capacity of this facility. This regional roadway r._, is presently operating at level of service D, which indicates that traffic �i service is adequate, but that momentary stoppages occur during the peak traffic periods. These delays are most frequent in the northbound lanes dur- � � � � ing the morning peak period and are most frequent in the southbound lanes dur- ing the evening peak peribd. The City of Burlingame Zoning Ordinance (1977) has requirements for off street parking provisions of new developments. All spaces must be nine feet in width and twenty feet in length, with a vertical clearance of seven feet,. exclusive of access driues. Enough parking spaces must be provided to allow one space for each lodging unit. IMPACTS. The proposed project would generate motor vehicle trips which would utilize the local and regional transportational systems of the area. Based � upon trip generation factors developed by the California Department of Trans- portation (CALTRANS), the proposed 214 room motel facility would generate j`� appro.ximately 1800 trip ends per day. Approximately Z00 of these trip ends j! �••1 would occur during the peak traffic period, 4:30 to 5:30 p.m. (CALTRANS, 1973). �., In order to assess the impact of project generated traffic on the local roadway Z� system, the methodology discussed under Existing Setting �as employed. The � I i results of this analysis are presented in Table 3. The levels of service for the major intersections shown in Table 3 indicate that the proposed project would not change the �1eve1 of service at these important locations. Traffic flow characteristics at these intersec�tions would remain at the existing level. 12 �� C-7 �� Ci � �'� �--� �� �-� � � � �� �� �� `�) ' � �� �� TABLE 3.

Source: Drachman, 1979 U (! � L! � � L� �� The proposed density of rooms of the project would be 86 rooms per acre. This is somewhat higtier than the development density assumed in the Drachman Traffic Study of 65 rooms per acre. The trip generation rate for the proposed project would therefore be somewhat higher than the nominal rate assumed in the Drach- man Traffic Study for the project site. The proposed project could have a cumulative effect on the major intersections of the Anza area, as other developments are added to this area. In order to quantify this cumulative impact, the methodology in the Drachman Traffic Study was applied to other approved projects and new project applications in the Anza area. These other projects are listed in Table 3(footnote a). As indicated. by the resulting level of service values in Table 3, the cumulative impact of the proposed project and these other projects could be significant. The inter- section of Airport Boulevard and Bayshore Highway would operate at level of service B and the intersection of Bayshore Highway with the U.S. Highway 101 on ramp would operate at level of service C. The City of Burlingame has established a development policy for the Anza area that limits development to minimize traffic congestion in the area. Implementa- tion of this policy will involve limitation of development to the extent neces- sary to maintain a level of service b or better at all of the major.intersec- tions (.City of Burlingame, 1978). For this reason, it can be concluded that the � proposed project would contribute in a cumulative fashion to the reduction in level of service of the ma�or intersections of the Anza area to level of service D. , � �:J This is considered an acceptable level of service in most urban areas, includ- ing the City of Burlingame (Moore, 1979). The project sponsor would be re- quired to pay a development fee to offset some of the costs associated with roadway improvement in the Anza area. These roadway improvements would be necessary as a result of the cumulative development of the area. One of the roadway improvements planned for the Anza area is an overcrossing ' between U.S. Highway 101 and Airport Boulevard, across the lagoon area. This overcrossing would include northbound on and off ramps for the freeway and � L' � � would connect to Airport Soulevard at the northwestern corner of the project site. The proposed project includes a secondary access point near the inter- section of the planned overcrossing and Airport Boulevard as shown in Figure 3. 14 { � �As development occurs in the Anza area and traffic volumes increase along Air- port Boulevard, turning movements along the roadway will become more diffi- �� cult. The proposed project would necessitate such turning movements along Airport Boulevard and along the overcrossing roadway and would create addi- tional conflicts with through traffic. Th2 proposed project would have an impact on U.S. Highway 101 traffic flow during the peak traffic periods. Fifty to seventy percent of the 200 trip f-; ends generated by the proposed project during these periods would utilize this tlregional roadway. Since U.S. Highway 101 is already operating at level of ser- vice D at peak hour, this additional traffic would cause further congestion and � delays along this facility. The initial site plans for the proposed project indicate that an adequate number of parking spaces would be provided to satisfy the City of Burlingame Zoning Ordinance. A total of 214 parking spaces would be provided. Of these 39 spaces would be designated for compact cars. The 175 full sized parking spaces would exceed the number required by the Zoning Ordinance by two spaces. The 21[, parking spaces should be adequate to accommodate the patrons arid em- ployees of the proposed motel. The lack of coincidence of maintenance employee shifts and maximum patronage periods would reduce the demands on available parking spaces. MITIGATION MEASURES. The following measures are suggested to minimize the traffic impacts of the project: � � � A shuttle bus service to San Francisco International Airport (SFO) will be provided by the motel operator on a demand basis at the project site � in order to reduce usage of U.S. Highway 101. This bus should run between �,.= the project site and SFO when patrons request this service and not on a regular basis, because of the expected low volume usage. The service � could,be combined with other local major generators of airport traffic, * such as hotels and airport parking vendors. i� � �' �'he applicant commits to these mitigation measures. � 15 �.1 � LJ � • Establishment (by the project sponsor) of a temporary Anza Pacific boule- vard to service motel access to the north if the proposed project proceeds � prior to the city's construction of the permanent Anza Pacific Boulevard . 2.3 VISUAL AND AESTHETIC PATTERNS EXISTING SETTING. The site is visible from both nearby and distant locations. In particular, the site is visible from Airport Boulevard (Figure 5, Plate 1), U.S. Highway 101 (Plate 2), the exterior of.the buildings to the north of Air- port Boulevard (Plate 3) and the row of apartments directly south of U.S. High- way 101. The second floor of these apartments have views of the site, U.S. � Highway 101, and San Francisco Bay. From greater distance, the site is visible from the Burlingame Hills (Plate 4). i.; � � � �I L � �I i The present visual character of the surrounding area, called the Anza Area, is a mixture of varied architectural styles and use of building materials. Con- crete walls, brick exteriors, wood shingles, and glass facades all exist in the Anza Area. Views to the west of the site are currently obstructed by a high mound of earth. To the north and east are seen the buildings previously described. The Bay is visible only to the east, while to the south lies U.S. Highway 101, and farther distant foothills. IMPACTS. Primary visual.impacts associated with the proposed project are occlusion of existing views, change in the visual character of the area and provision of new views. Little obstruction of existing views would result from the project since the land surrounding the site is largely vacant and primarily of low intensity daytime use. The proposed views to be affected by the project would be for pedestrians, bicyclists, and motor vehicle passengers along Airport Boulevard, the pro- posed Haliday Inn Building east of the project site, and distant locations in the Burlingame Hills. In none of these instances would existing views be blocked to any substantial degree, however. The site is not visible from the � The applicant commits to these mitigation measures. 16 a � r� c�. � 0 �� -�, �� � � C C� C � � � � u � ���, earth metrics FIGURE 5.

The proposed motel building would be approximately 46 feet in height, from curb elevation to the building parapet. The building width along Airport Boulevard would be 58 feet, and would have a length of 278 feet. The proposed structure would be rectangular, occupying approximately 17 percent of the site. The building would be situated approximately in the center of the site surrounded on all sides by parking spaces. A smaller building would be located along Airport Boulevard, containing an office and coffee shop. A forty foot pool would be adjacent to the motel to the south. Because of the project location and linear orientation to the building on site, the building would be perceived as an object of significant size only from certain locations. This is supported by the computations of ares of vision and relative field of view for the proposed building, from a vantage point on Anza Pacific Boulevard, the roadway proposed to the west of the project site. The arc of vision is the angle (in degrees) subtended by a structure from a par- ticular observer position. An arc of vision of approximately 90 degrees would indicate that a structure approximately fills the entire field of view (in a particular sense, horizontal or vertical) of an observer at the specified loca- tion. The relative field of view is a comparison of the ares of vision of dif- �j ferent structures. Bayside Boulevard was chosen as a vantage point for these Lt calculations, since this roadway would bel�eavily traveled when the connection between Airport Boulevard and U.S. Highway 101 is completed; this vantage � point also represents the aspect of greatest numerical visual impact. � � f'! �I Compared to other local buildings, the horizontal arc of vision spanned by the motel (as viewed from the curb of the new street) would be among the largest in the area. The vertical arc of vision and relative field of view would be less significant because of the lack of height relative to other area struc- tures. Table 4 summarizes the result of the computations. I3ew views of San Francisco Bay to the east and the foothills to the south would be provided to motel patrons from the interior of the motel. The proposed building exterior would be of glass, concrete block and brick veneer construction. The side elevation of the proposed building, stiown in � 19 i� �J � 11 � � f �, � � L�% � � � � � � � i I L; Figure 6, indicates that a majority of the building would be glass windows and doors. A continuous aluminium railing with vertical bars would span the entire length of each floor along the outside walkway. The small non glass areas of brick veneer proposed between each room would serve to break up the length of the building. Three large rectangular brick covered areas are shown in the side elevation. The center block area would extend from ground level to beyond the roofline, while the two other block areas on both ends would extend only to the fourth floor. These brick covered structures would also relieve the glazed areas. TABLE 4.

MITIGATION MEASURES. The following mitigation measures are recommended to alleviate visual and aesthetic impacts that may result from the proposed proj- ect: • Plant evergreen trees initially approximately 15 to 20 feet in height �, visible from the street elevations. The landscaping plan is to be reviewed and approved by city staff.� � � �` l� � ,L: i �� V • Provide mounding along Anza Pacific Boulevard a.pproximately four to five feet in height and landscape to soften the parking area.* • Brick towers on the Anza Pacific frontage are designed to provide depth and break up the mass of the structure.* • Insure that the proposed aluminum railing is of anodized color, earth tone, or other neutral color, along the length of each floor.* XThe applicant commits to these mitigation measures. 23 �� �-., 2.4 DESIGN GUIDELINES FOR BAYFRONT AREA EXISTING SETTING. Burlingame City Council Resolution Number 9-80,adopted February 19, 1980,sets forth Design Guidelines applicable to land developments ��. in the Anza Area. The Besign Guidelines apply to building height, setback, �-= view corridors, public access, landscaping and parking. Building height and � L,.'� � I, � � � � t.�', � L � landscaping are addressed in the foregoing visual analysis section of this report; public access and parking issues are addressed in planning and trans- portation analyses. � The principal matters analyzed in this section are setback and view corridors. Section 3 of the Guidelines provides that (i) street setbacks should not be less than the building height, (ii) the minimum setback should also be not less than half the apparent width of the building for the adjacent street,and (iii) in all cases a 30 foot minimum setback shall apply to any portion of each building. Under Section 4 of the Guidelines (applicable to view corridors and visual access to the shoreline) it is specified that (i) a building located within one half its apparent width should not obstruct more than 40 percent of the frontage; (ii) a building located at a distance greater than its apparent width (from the street) should not obstruct more than 60 percent of the frontage; (iii) buildings, structures, parking lots and landscaping of new shoreline projects should be planned so as not to detract from views of the bay from nearby public thoroughfares; and (iv} shoreline development should be clustered to allow bay views and access between building clusters. The City Council further interpreted the Design Guidelines•in May, 1980 to apply on multiple sides for a parcel having exposure to two or more streets. IMPACTS. The proposed project plan has been analyzed with respect to Sec- tion 3 and 4 of the Design Guidelines and comparisons are made with alterna- tive building footprints to provide further insight to design alternatives. levard at the nearest protrusion, and 62 feet at the farthest wall.

All alternative designs will be in compliance with the guidelines if Alternatives B, C, and D are madified to correct the slight deficiencies indicated in Table 6. Function and Aesthetic Comment on Alternative Motel Footprints. Alternative motel footprints set forth in Alternatives B and C do not allow convenient �;' parking near an appreciable number of rooms; it is an important marketing 4J consideration in the motel industry to provide parking immediately adjacent i � �J � U � C � ��I �1 to a maximum number of units. Alternative D, with the pool situated at the southeast end of the motel struc- ture, would allow almost as much close in parking as the applicant's proposed plan; view corridor access from U.S. 101 would be narrowed slightly; and fire protection access to rooms on the southeast property side would be somewhat inferior to the proposed plan. Alternative A or F(provided that the pool is located at the southwestern side of the motel structure) would offer less parking convenience than the applicant's proposed footprint. Its view corridor intrusion, as seen from U.S. 101, would be greater than tfie proposed plan. Circulation and fire protection areas would also be hindered relative to the proposed plan. The energy efficiency of these plans is less than the proposed plan due to energy losses associated with hot water transport. MITIGATION MEASURE � The applicant is in the process of preparing a supplementary analysis of Alternatives A and F and will submit a separate report on their viability to the City of Burlingame. � 34 TABLE 6.

At present, the project site is vacant but fenced so that no public access to the lagoon area adjacent to the site now exists. There is, however, no designated public access corridor through this site. Public access in the Anza Area is one of the objectives of the Callander Plan. This plan, designed by architect Peter Callander for the Anza Shareholders Liquidating Trust, seeks to provide a landscaping plan for the entire Anza Area. This plan shows a pedestrian path along the north, west and south boundaries of the project site. IMPACTS. The completed motel would remove an open space corridor to the nearby lagoon. Corridors would be required through the project site to the shoreline easement. One mode of designated pedestrian access to the lagoon area from Airport Boulevard would be via a proposed five foot wide green strip around the property. Other modes would require pedestrian access through the parking area. The site plan currently under study does not indicate that such modes of access would be clearly marked to a pedestrian, but such markings could be incorporated into the site design. In terms of access, motel usage of the site is considered to be a public rather than private use by the City of Burlingame. For this reason, the city con- siders a motel to be preferable shoreline use to private use, such as office or residential development. The BCDC, which has jurisdiction over the 100 foot shoreline band bordering the lagoon area, has responsibility for maintaining public access to the shore- line. Determination of maximum feasible public access to the Bay would be re- quired by BCDC before approval of a shoreline permit for the proposed project would be granted. MITIGATION MEASURES. The following measures are suggested to mitigate the im- pacts previously discussed: • Provide a clearly marked public access pedestrian pathway through the pro- posed project, from Anza Pacifid Boulevard to the lagoon area. The path � � � should be signed, and it should be designed with surface material to �--,, clearly delineate the path's presence to pedestrians. C_.1 � U � l_.i � � � � �I� � 37 L� U � 2.6 ENERGY EXISTING SETTING. The energy setting of California and the nation in general is a critical one of increasingly higher energy costs and depleting nonrenewable i energy sources. The energy problem is compounded by increasing demand for energy resources. State and federal policy seeks resolution through energy (�� ' conservation and development of alternative energy sources. The degree of suc- U cess of this strategy depends on coordinating local and regional policies Q �J l�.J �! � � � i � and fostering public awaren�ess. The Warren Alquist State Energy Resources Conservation and Development Act (1974) created the California Energy Resources Conservation and Development Cotmnission (CERCDC). The State Energy Conservation Action Plan was prepared by CERCDC, under provisions of the Energy Policy and Conservation Act (FL 94- 163) and the Energy Conservation and Production Act (PL 94-385). Energy con- servation standards f or new residential buildings were adopted by CERCDC on March 11 and March 23, 1977, and are enforced by local building departments through the existing building permit process. Motels are included in the resi- dential standards. The energy consexvation standards for new residential build- ings have been placed in Title 24, Part 6, Division T-20, Chapter 2, Sub- chapter 4 of the California Administrative Code. The standards are intended to provide energy savings through the design of the component parts of these buildings and the building envelopes. The envelopes must have good thermal resistance and low air leakage, and mechanical and electrical systems providing heating, cooling, lighting, and hot water must use a minimum amount of energy. Compliance with the standards necessitates various indicated calculations and the completion of special compliance forms. State energy policy also includes measures to reduce regional vehicle miles of travel by automobiles, and thus gasoline consumption. At present, no energy consumption is associated with the project site. IMPACTS. The proposed future development of the project site will have two impacts on energy consumption: the operating energy cost of the motel and the, energy cost of construction. Development of the proposed project will entail 38 � l� � � � [_.! �} � the use of earth moving and grading vehicles, electric, and pneumatic tools, and various other energy consuming equipment. Additionally, the commuting of construction workers and hauling of construction materials leads to transporta- � tion consumption of energy. This demand phase of construction is short term, and is not as taxing as the long term operating and maintenance energy con- sumption. , The operational energy needs of the proposed project will be supplied by avail- able natural gas and electricity lines maintained by Pacific Gas and Electric Company. Energy will be required in the operation of lighting, air condition- ing, space heating, water heating, and appliances in the proposed structures. As discussed in the visual analysis, the exterior materials, will probably be con- crete and glass. The overall amount of glazing and the type of glass used in the motel will greatly affect the energy consumption associated with the total project. However, energy consumption must meet the minimum requirements set by the state residential and non residential standards. The impact of the project on energy conservation ef.forts will depend largely on conservation measures practiced beyond the scope of the state minimum requirements. 0 �Energy consumption associated with the proposed project will also result from .�„� site generated traffic and the consequent demand for gasoline. Gasoline con- sumption of trips attracted to the project is estimated to be 1350 gallons � � per aay, based upon an estimated vehicle miles traveled (VMT) of 27,000 miles per day. A composite gasoline economy of 20 miles per gallon for vehicles in 1981 is assumed here. s � MITIGATION MEASURES: MOTEL �he following mitigation measures are suggested for energy conservation: •'Use double,glazed windows to reduce the amount of heat loss through these areas.* � � L_.:� • The penetration of solar radiation through windows can be controlled through the judicious use of awnings, i�terior draperies or special 39 � i blinds that can be drawn between the two panes of double glazed windows, I or by a variety of types of externally projecting shades which may take the form either of vertical fins or horizontal "eyebrows" that cut off �� high angle summer sun but allow low level winter sun to enter (Steadma.n, _.. 1975). � � Use weatherstripping around doors; windows, vents, or other areas where r-� warm or cool air may escape. • Install time clocks or photocells adjusted to control outdoor or � l safety floodlighting, or other non localized controlled lighting. j; • Locate water heaters as close by as possible to the demand locations. ��s �• Position the swimming pool to take maximum advantage of direct solar � illumination. �--' Building Materials and Construction �' • Utilize local sources of building materials wherever possible to U mini.mize transportation related expenditures of energy resources. , • All equipment should be properly tuned and have reasonable energy �i efficiency. Idling time should be minimized. • Prior to construction of the project, detailed energy consumption � analysis is required under the CERCDC residential energy code. *The applicant cammits to these mitigation measures. � �i ��� 40 � , , 2•7 ECONOMICS l� �, EXISTING SETTING. For the City of Burlingame, the two relevant taxes that af- � ` fect the general fund tax base are real property tax (secured and unsecured) and the retail sales tax. Revenues other than those that accrue to the general � fund (such as building inspection fees) are not described, as those are de- signed for direct payment of specific services rendered. 1 Passage of the Jarvis Gann initiative in June, 1978 reduced property tax reve- � nue to all local governments in California. The reliance of local governments �� on real property tax revenues has been reduced only to the extent that the lost � revenues have been replaced through state (subvention) allocations, increases �� in local fees, and other revenues. j The market value of the project site is currentl y $829,905, representing an assessed valuation of the site at $207,476. In accordance with Proposition 13 � (the Jarvis Gann Initiative), a one percent tax rate is assessed against the property. The property in its current vacant state, contributes $8299 to the countywide tax base of which $500 is distributed to the City of Burlingame. � IMPACTS. The continuing expansion of San Francisco International Airport is � expected to generate market support for a variety of commercial ventures of which hotel/motel activities and the associated restaurants are noteworthy � (Blayney, 1977). ) The proposed 214 room motel would generate approximately 30 to 32 new permanent jobs for the immediate area (,Tames, 1979). These jobs are considered to be � basic new jobs that would be created by the motel. According to the Association of Bay Area Governments (�1BAG), 1.08 service jobs elsewhere in the economy can be expected to be generated for each basic job (ABAG, 1978). Therefore, approxi- � ,�, mately 35 service sector jobs.could result from the proposed motel or a total of 67 new jobs. This could translate into approximately one million dollars � of payroll to be added to the mid peninsula economy. Temporary economic bene- � � �f fits would also result from the motel construction. The total construction payroll could be as high as two million dollars, a portion of which would be received by the local economy. _ 41 � � I � � i � Municipal Revenues. Property taxes per annum are now equivalent to a tax of one percent of the fair narket value of property. The project proponent has estimated the fair market value of the motel, including the land, to be $6,250,000. This would generate an annual property tax revenue of $62,500. , Such tax revenues would accrue to the county, with the portion allocated to the city being $4281 annuallyl. Sales Tax revenues to the City of Burlingame of $91 per room per year is expected from the eating and drinking establish- ments within the motel (Blayney, 1978 Revision). This would total $19,474 per year to the city. Transient lodging taxes, currently at eight percent, would yield revenues of approximately $800 per room per year or a total of approximately $171,200 per annum2. These revenues are presented in Table �. L_..� . , TABLE 7.

The services that would be tangibly af- fected by the motel project are police, fire, and public works. The police department is reported to have estimated that the area north and east of U.S. 1SB 154 provided a formula that translated into a tax factor of .0685 for the City of Burlingame. 2 $35./unit/day at 80 percent capacity 42 � � � � � ` � � � � r � � �� t � Highway 101 would require one patrol beat, when the area achieves full devel- opment. Currently, the area operates on one half of one patroT beat. The cost to increase from one half of one beat to a whole beat is estimated at $87,000 per year (Blayney, 1978). Fire services were estimated by Blayney to be approximately $6040 per million dollars of assessed valuation, thereby giving the motel fire protection at a cost to the city of $36,000. The capital costs borne by the Public Works Department would include the costs for construction of roadway'improvements along Waterfront Area, estimated to be two million dollars (Kirkup, 1979). The city has.already adopted develop- ment charges to defray the cost of 40 percent of these expenses. At present, the city is responsible for the remainder of the cost, which it expects to be paid from gas tax revenues and grants (Argyres, 1979). The applicant would have to con- tribute $11,770 toward the improvements to the waterfront roadways as Burlingame City Ordinance Number 1151 establishes development fees of $55 per room for new hotels (Kirkup, 1979). � The cumulative fiscal imp�ct shown in Table 8 would provide a net annual sur- plus of $689,955 to the City of Burlingame. Other projects located in the Anza Area would probably increase the surplus to the city. MITIGATION MEASURES. No mitigation measures are required. TABLE 8.

The project site is situated on fill material that was placed over land reclaimed from marsh and tidal lands in the early 1960's. A soil boring study conducted in 1977 on an area one half mile east of the proj- � ect site (Crandall and Associates, 1977) found that the existing fill is four to five feet in thickness and consists of silts and clays containing some de- �. t� L�t molition debris. The natural soils immediately beneath the fill consist of highly compressible soft clays (bay mud) four to nine feet in thickness. Be- low the bay mud are deposits of stiff clays and dense gravelly sand approximately 30 feet in thickness. Below an elevation of approximately minus 40 feet, dense gravelly sands were encbuntered. Based on these soil borings and gener- al information on the geology of San Francisco Bay, it can be assumed that be- neath the fill layers on the project site is a thin layer (4 to 5 feet thick) � of highly compressible bay mud underlain by more competent soil layers com- posed of alluvial material. I U � L_,) � Because of the low elevation of the project site, groundwater elevation should be anticipated to be shallow. Crandall and Associates (1977) found ground- water levels, below a similar filled area one half mile east of the site, to be 5.5 feet below the ground surface. Other previous investigations in the project area indicate that groundwater may be as shallow as one foot below the surface. The principal geologic hazard at the project site is ground shaking associated with seismic activity. The project site (as well as most of the San Francisco Bay Area) is situated within one of the most seismically active regions of the United States. At any time during the next 50 to 100 years, one major (magni- tude 8 plus on the Richter Scale) and possibly several moderate (6 to 8 magni- tude on the Richter Scale) earthquakes can be expected in the San Francisco Bay Region (Jahns, 1972). Structural damage could result from the transmission and earthquake vibrations from the ground into overlying structures. Buildings construr•ted on uncon- � solidated, water saturated materials (such as those beneath the project site) generally experience greater ground shaking intensities than buildings sit- �I , � , uated on more firm ground. However, in the event of an earthquake, structures 44 � �I � � i...! � � ii U �' � � � � with proper seismic parameters incorporated into their construction may dis- play minimal damage. Liquefaction is a form of ground failure in which cohesionless, granular, water saturated material is transformed from a solid state into a liquefied condition. The generally cohesive clayey subsoils within the project site area indicate a low potential (low risk) for liquefaction to occur. Surface rupture usually occurs along lines of previous faulting. Since there is no evidence of active faulting in tIie i�ediate vicinity of the site, the chances of surface rupture across the site are remote. IMPACTS. The propos.-ed project would b.e constructed on ground that has not previously supported heavy building loads. Approximately 18,100 cubic yards of earth fill would be imported to bring the site to elevation of the present curb level. The building foundation would probably be supported on piles driven into competent alluvial layer below the Bay Mud. The Bay Mud beneath the project site has been compressed by the weight of tfie overlying fill for more than 15 years. Analyses b.y Seid (1969) and Crandall and Associates (1977) indicate that the settlement within tlie mud may be considered essentially complete under exist- ing conditions. The placing of additional fill and structures supported by the fill on the project site would cause the underlying soft Bay Mud to compress further, resulting in additional settlement. The magnitude of settlement is expected to he approximately 0.75 inch per foot of fill placed. Total settlement of pile supported building would probably tie less than one half inch. Differ- ences in the amount and rates of settlement between pile supported structures and structures. supported on tfi.e fill could cause damage or operational problems where utility lines, stairways, walkways, ramps, gravity drains, and other structures supported on that fill are connected to pile supported buildings. Settlement problems on the project site, albeit present, are not critical and can be mi- tigated with normally accepted engineering practices. Severe ground shaking can be expected at all of the project facilities in the event of a moderate or greater earthquake in the area because the entire proj- ect site is situated on generally loose, unconsolidated deposits. This ground shaking could cause extensive damage to buildings, roadways, utility lines, and other structures that are not properly designed. 45 �= i � MITIGATION MEASURES. The following recommendations are presented as guide- lines for subsequent stages of development of the proposed project. • A detailed soil and foundation engineering investigation should be conducted for the development prior to building construction or site grading. The investigation should provide detailed recommendations for foundation design, site grading, drainage, and road construction. • Flexible connections should be used for all subsurface utility lines. �( • The risk of significant structural damage to buildings and injury to � building occupants can be significantly mitigated with proper struc- i' tural design, sufficient lateral bracing, an adequate foundation sys- tem, and good construction techniques. The 1976 Uniform Building �'� Code requires that seismic design parameters be incorporated into all � new building plans. � • To minimize effects of differential settlement activity on site, special attention should be given to the following considerations during the design of foundations and paving support to: 1) underground pipe connections to pile supported structures; , 2) structural connections from pile supported to non pile supported � structures; i!J 3) ground supported walks, stairs, and ramps serving pile supported structures; and i.,� 4) gravity drains serving pile supported structures. �J --, � �l 46 LJ! I� 2.9 AIR QUALITY EXISTING SETTING. The San Francisco Bay Area Air Basin is designated a non- attainment area for oxidant, carbon monoxide (CO), and particulates. Non- attainment refers to those areas that, by virtue of past air quality monitor- ing.or air pollutant emissions growth trends, violate the National Ambient Air Quality Standards (NAAQS). Local, state, and federal agencies are currently involved in the formulation of plans and policies to reduce pollutant levels in such nonattainment areas. ' The Bay Area Air Quality Management District (BAAQNID) operates air quality I monitoring stations throughout the Bay Area and in the City of Burlingame. �'� . Recent records of this monitoring indicate that very few violation days for �� the air quality standards occur in the City of Burlingame, as compared to the LJ rest of the Bay Area. Table�9 presents a summary of the air quality monitor- � ing performed in the City of Burlingame for the period 1975 to 1977. This table indicates the maximum concentrations of pollutants that occurred in � the City of B.urlingame each year, and the number of days that the ambient � air qualit}� standards were exceeded. The air quality standards for the State �I� 1 � �.J � � � � i � of California are presented in Table 10. The California Air Resources Board compiles inventories of the primary pollu- tant emissions for existing and future years for the air basins of California. Table llpresents these inventories for the San Francisco Bay Area Air Basin. These values indicate that mobile sources, of which private automobiles are the largest component, account for the majority of the carbon n}onoxide, reac- tive hydrocarbons, and nitrogen dioxide emissions in the air basin. Reactive hydrocar.bons and nitrogen dioxide are precursors of oxidant. (Particulate and sulfur dioxide emissions in the San Francisco Bay Area Air Basin are largely the result of non motor vehicle sources.) IMPACTS. The proposed project could affect local air quality during the construction and operational uses of the project site. Construction activi- ties can produce high local levels of particulates if not mitigated. The transporting of materials to and from the project site also contributes to regional motor vehicle emissions. 47 (_�.`� I~`_? � f_`�`) � �`1 �l �"l � �l C-`"_l C� � C_`�� C�..1 �_�_� �1 �`�) � TABLE 9.

The standard is 0.05 ppm during 24 hours in com- bination with oxidant levels over the state one hour standard of 0.10 ppm or particulate matter in excess of the state 24 hour standard of 100 ug/m3. The new S02 standard was adopted to prevent the synergistic effects of combinations of these air pollutants on human health. � L� A �. �� � � � TABLE 11• EXISTING AND PROJECTED EMISSIONS RATES FOR SAN FRANCISCO BAY AREA BASIN (TONS PER DAY). �� l.J �J � U �` L �I POLLUTANT INVENTORY �EAR • SOURCE TYPE 1975 1980 1985 1990 Carbon Monoxide • Mobile 2850 1620 1110 1030 � Stationary 260 280 310 340 • All � 3110 1900 1420 1370 Organic Gases • Mobile 420 290 190 150 � Stationary 440 400 440 500 • All 860 690. 630 650 Nitrogen Oxides • Mobile 410 380 300 290 • Stationary 220 280 310 360 • All 630 660 610 650 Particulates • Mobile , 60 50 50 50 • Stationary 110 140 150 180 • All 170 190 200 230 Sulfur Oxides • Mobile 40 50 50 60 • Stationary 180 280 320 390 �• All 220 330 370 450 Source: ARB, 1978 � � sn �� !. � , ! Assuming an average trip length of approximately 15 miles, the operational use of the project site would generate approximately 27,000 vehicle mi�les ��, of travel (VMT) per day. Although this would not cause a significant increase in motor vehicle related emissions in the Bay Area, it would have a cumula- �}�� tive impact on regional air quali'ty. Tablel2 presents the amounts of pollu- I� . . tant emissions that,would result from the proposed project. These figures (�' indicate that the project would add less than one tenth of one percent to the � daily emissions of the San Francisco Bay Area Air Basin. i..-' MITIGATION MEASURES. The following measures are suggested to minimize the construction and operational air quality impacts of the proposed project: � • Wet down areas of soil redistribution to keep dust from blowing. � • Use,properly tuned construction vehicles. • Avoid unnecessary idling of trucks and other equipment during construction. • Use locally available materials, where practical, to minimize emissions attributable to hauling. �i • See mitigation measures under Traffic and Transportation for means � of reducing operational air quality impacts of the proposed project. � � � �"1 � 51 � � � � �h I I �: � � � , � I � � I' ..� ��I � � U � .j � � � l..l �� U � TABLE 12• PROJECTED EMISSIONS RATES FOR THE PROPOSED PROJECT IN 1990 POLLUTANT TYPE 1990 MOBILE SOURCE PROJECT RELATED PERCENTAGE OF EMISSIONS FACTORa EMISSIONSb 1990 SAN FRAN- (GRAMS PER MILE) (TONS PER DAY) CISCO BAY AREA AIR BASIN MO- BILE SOURCE EMISSIONS (%) Carbon Monoxide Organic Gases (�on reactive hydrocarbons) Nitrogen Oxides Particulate Sulfur Oxides 11.5 1.08 1.98 0.25 0.13 0.340 0.032 0.058 0.007 O.00G� 0.03 0.02 0. 02 0.

This discussion of the archaeological sensitivity of the project site is based on information included in Environmental Documents for development previously proposed in the project vicinity. The most compre- � hensive and pertinent of these reports was prepared for a proposed office � building to be built on the northern side of Airport Boulevard, approximately �' 1200 feet east of the project site (City of Burlingame EIR-45 P, 1977). A field reconnaissance and a review of archaeolo ical records on file with the g State Parks and Recreation'Department in Sacramento and San Francisco State University was perfromed for the above cited EIR. The literature search indi- cated that there are no known archaeological resources on the office building �, site, the project site, or in the immediate surroundings. The field survey for the office building site revealed no surface evidence of archaeological L� resources at that location. The probability of encountering unknown archaeo- logical resources on the project site is low, since the site is composed of � landfill and little evidence of cultural resources has been detected in bay ti�1 muds and landfill in this general area (City of Burlingame EIR-45 P, 1977). � IMPACTS. No known archaeological resources would be affected by the proposed project. There is a small potential for disrupting unidentified resources � during excavation activities. � MITIGATION MEASURES. The following measure is suggested to reduce the proj- ect's effects on unidentified archaeological resources that may occur at the project site: • If archaeological materials are encountered during excavation of the site, construction work should cease until a qualified archaeologist can assess the find and provide appropriate recommendations. A member of a Native American group should also be consulted, since any potential resources found are likely to be indications of previous Indian habi- tation of the area and could be important to the Native American heri- tage. � � 53 � I L.i I' .�.i 2.11 NOISE EXISTING SETTING. The Noise Element of the Burlingame General Plan was adopted September 15, 1975. It contains land use planning criteria that specify the maximum acceptable indoor and outdoor noise levels for various land uses. The applicable criteria for motel developments are a maximum indoor noise level of 45 CNEL and a maximum�putdoor 1eve1 of 65 CNEL. The CNEL noise level is - a weighted average of daytime and nighttime noise levels. The 1975 noise con- tour maps presented in the Noise Element indicates that part of the project site nearest U.S. Highway 101 is presently exposed to noise leyels between 65 and 70 CNEL. IMPACTS. A 1990 noise contour map is presented in the Noise Element that ��1 t_.l �' � �' � provides projections for noise levels at the project site. These contours indicate that only the portion of the project site within 100 feet of Airport Boulevard will be exposed to noise levels above 65 CNEL. Beyond this dis- tance, the noise levels will drop below 65 CNEL. This improvement in the noise environment of the project site over 1975 conditions would be the re- sult of legislated and expected reductions in motor vehicle noise emissions. The proposed motel structure would be set back from Airport Boulevard approxi- . mately 150 feet, so that exposure to roadway noise in excess of 65 CNEL would be ininimal. If the proposed lagoon overcrossing between U.S. Highway 101 and Airport Boulevard is completed (see traffic section of this report), future noise levels at the project site would be higher than those indicated in the 1990 contours. Large portions of the project site would be exposed to noise levels between 65 and 70 CNEL. Proper acoustical design for the proposed structure would be necessary to reduce interior noise levels to comply with the 45 CNEL planning criteria. Exposure to aircraft noise is not a significant contribution to noise levels at th.e site. The nearest flight path to the project site is over one mile to the north. The motor vehicle trips generated by the proposed project would not have a significant e.ffect on the local noise environment. The increase in noise 54 �! !1 levels along Airport Boulevard caused by project generated traffic raould not „�, be noticeable to any observer along this roadway. � � MITIGATION MEASURES. The following measures are suggested to minimize the � noise impacts of possible lagoon overcrossing on the proposed project: ,_, I. . • All doors and windows on the west side of the proposed motel build- ing should be thoroughly caulked and weatherstripped to insure that air leaks are eliminated. The doors and windows of the motel office should also be treated in this fashion. • All roof/wall interfaces should be thoroughly caulked to prevent air Zeaks. The motel office structure should also be treated in this f ashion. � �a Conduct a detailed acoustical analysis of wall effectiveness to determine I the measures required to bring interior sound levels to a level of 45 dB CNEL. This analysis should be conducted prior to issuance of the build- � �� ing permit. .. ` 1� � �� �� � - ��� � 55 Ij L� L 2.12 BIOLOGY EXISTING SETTING. The natural habitats in the project vicinity have largely been replaced by urbanization. The 2.5 acre project site consists of un- developed land bordered by Airport Boulevard, parking facilities, and a large lag�on area. Vegetation. Approximately one third of the site is nearly devoid of vegeta- tion. This barren area con�sists of a paved parking area and adjacent unpaved L,,! area which have been denuded by vehicle movement. The remaining two thirds of the site support low, sparse grassland. Species composing this grassland are �- primarily introduced annual grasses and herbs that are indicative of a disturbed habitat. Frequently occurring species are: rabbitsfoot grass (Polypogon mons- �) peliensis), wild oats (Avena fatua), annual ryegrass (Lolium multiflorum), �.. � farmer's foxtail (Hordeum leporinum), lamb's quarter (Chenopodium album), � brass buttons (Cotula coronopifolia), mustard (Brassica sp.), sow thistle (Sonchus oleraceus), bristly ox tongue (Picris echioides), and saltbush (Atri- � plex sp.), Brass buttons, saltbush, and rabbitsfoot grass are characteristic of saline soils. No trees or shrubs exist on the site. � i, I Wildlife. There appears to be a low number and diversity of wildlife utiliz- ing the site, based on an Earth Metrics site reconnaissance of July 3, 1979 and information contained in Environmental Impact Reports prepared for previously proposed developments in the project vicinity. Factors that contribute to the low habitat value of the site include: lack of vegetation for food and cover, lack of adjacent, natural open spaces and terrestrial outlets to such areas, noise related to traffic on U.S. Highway 101 and airport operations, and other effects of human intrusion. The only wildlife observed by Earth Metrics on ' the site was blacktailed jackrabbit and killdeer. It is probable that other common fauna that are tolerant of human activities occur on site, such as: Norway rat, black rat, house mouse, Botta pocket gopher, house finch, gulls, starling and house sparrow. �� Rare and Endangered Species. No plants designated as rare and endangered by ,�; the state or federal agencies, or the California Native Plant Society inhabit �the project vicinity (Griggs, 1979). Of the four rare or endangered wildlife �I. �. Sti � L species known to occur in San Mateo County, none have been identified in the project area (San Mateo County Planning Department, 1973 and the California Department of Fish and Game, 1974). IMPACTS. The proposed project would replace 2.5 acres of disturbed habitat with approximately 0.5 acres of landscaping and two acres of impervious park- ing areas and buildings. Vegetation. The sparse coverage of common annual grasses and herbs would be replaced by the proposed facilities. No unique, particularly productive, or aesthetic plant growth would be removed. Landscaping would reestablish vege- tation on 21.25 percent of the project land. Although cultivated turf areas are proposed, there is not yet a detailed landscaping plan for the proposed I project. Landscaping that includes exotic trees, shrubs, and grasses often requires irrigation, pesticides and fertilizers and is of low habitat value to wildlife. Wildlife. The proposed project would not affect any valuable or unique wild- Ilife habitats. However, the proposed facilities could be of even less value to wildlife than the existing low quality habitat. If landscaping utilizes plants i � that provide wildlife food and shelter, some habitat would be available for use by tolerant animals, primarily common perching birds. Rare and Endangered Species. No impacts to rare or endangered plants or ani- mals are expected to result from the proposed project. MITIGATION MEASURES. The following measures are suggested to enhance the habitat value of the proposed project: • Landscaping should include plants that are of food value to wildlife, are wind resistant, drought resistant, and/or tolerant of soil salinity. � Some recommended species are: autumn olive, Monterey cypress, myoporum, cotoneasters, coyote brush, hollyleaf cherry, sagebrush wormwood, Brewer's � saltbush, and pyracantha. ,(� • Topsoil should be imported to improve soil fertility and displace local � saline soils. Planting holes and beds should be carefully prepared so that the compacted fill is broken up to improve drainage. �� � � 5 7 � L � 3 REFERENCES: ORGANIZATIONS, PERSONS, AND PUBLICATIONS CONSULTED Argyres, Dennis, City of Burlingame Finance Director, personal communica- tion (1979).
