T'he Conservation Element of the Burlingame General Plan notes that of tlie total length of creeks in Burlingame, only a small portion remain in a state approximating natural conditions, and the remaiping length has been either reclianneIed, concreted, undergrounded or otherwise modified. The conservation element prog�am goal is to retainpresent natuial sections of the creek system in a nattual condition. Programs to meet that goal are to inform the public of the part creeks play in the ecosystem to instill an understanding and respect of the creek systems; and to study soil stability, vegetation and bank conditions along the creeks and regulate appropriately. Mitigation: � A creek enclosure permit for the proposed culverting of a 82' section of the creek shall be required before any conshuction is allowed: ---Popt�tion and Housing Snmmary: This site and the surrounding area aze planned for low dansity residential .., : -—uses. -'Fhe project will-not result-in-a-change-to_the number_ofhousing_units_nor will it affect area.population. _ __ Geologic Summary: The site is located in the fully developed lrillside area of Burlingame, an urban setting wlrich has been developed with single family homes for about 50 years. The site is appro�umately 1 mile &om the San Andreas Fault but is not witliln the Alquist-Priola zone; the site is less fl�an 1/2 mile from the Sema Fault, a minor Uuust fault considered to have common mots with the San Andreas Fault. There aze no ]mown faults on the site. The construction of the culvert will not affect the seismic exposure of the site. The pipe extension will be placed in the existing creek alig►ment. Earth fill will be placed (approximately 500 cubic yazds) and compacted over the pipe to the progosed grades shown on the project plans. Earth $11 will be placed 'm 8-inch lifts and compacted with a"sheep's foot" type compactor. A concrete headwali will be constructed at the upstream end of the culvert extension. The soils engineer notes in a geotechnical invearigation (February 2002) that the subsurFace materials below the upper fill and topsoil are very stiff clay�y, weathered bedrock, in addition to hard, &esh rock, and these coriditions may help to teduce the intensity of shaking in a seismic event Since no fault traces are mapped thraugh the site, ground surface rupture is no8.bkely at the site. No loose, saturated s��y-soirs were encountered; and therefore, liquefaction is not considered likely to occur. The site sTopes are steep, and there have been past failures wlrich appear to have been related to undermining of the base of the slope by the creek, Shaking during a strong earthquake could inciease the likelihood of fuhue failures. However, the proposed Sll in the creek chaffiel will increase the stability of the adjacent slopes by buttressing tha steepest portion of the slopes along the creek bottom. The soils engineer conctudes that this site is geotechnically suitable foc the conslruction ofthe proposed creek filt provided the recommendations contained in the geotechnical report are included in the design and cazried out during the construction. Recommendations for site preparation, earthwork, and drainage are included below as mitigation. MitigaHon: • The condition of the existing sanitary sewer line should be investigated and repaired as necessary. • Work on the existing creek shall be perfoimed only dwing the "dry" season (May through October) to reduce the potential for slope failures during the excavation work and the possible need for dewatering (in addition to the diversion ofthe creek flow). Initial SYudy Summary 2202 Summit Drive • A geotechnical engineer should be engaged d�smg the work to obsetve the excavation ctits and provide advice on the need for shoring of the existing improvements until all the fill has been placed. -. The fill placement and compaction work shall be performed in a"dry" condition. • Removal of rocks, boulders, loose and unconfined soil and rock debris, vegetation, organic soils, and other debris and rubble from tfie creek bottom and sides shall be reviewed in the field by the project. geotechnical engineer at the time the work is in progress. • Portions of the existing rip rap shall be removed where it has been undernrined. • Ground azeas that are dishubed during the clearing operation and other void or "hollow" areas shall be properly backSlled using the native soil and rock, or approved import soil, by compacting the backSll material to a Minimum Relative Compaction of not less than 90% of the Maximum Dry Density as determined by ASTM Test Procedure D1557. • Native soils and rocks (acceptable for use as fill material) and import fill material should be placed in layers, no tlucker than 8 inches, moisture-conditioned, and compacted. � � Prior to use on the site, all import fill material shall be submitted to the geotechnical engineer for . __ ��pec6on,-fcs6ng (as.necessary_),_and final_aggroval_ for.use on the, site._ � -- _ ---- — •'I'hat the rip rap shall be underlain by a filter fabric to help reduce the potential for fitture erosion and loss of the soil under the rip rap caused by water infiltration. • T'he surface of the new Sll section should be provided with a means to minimize erosion of the near- surFace soils. Existing surface drain pipes shall be connected into new collector pipes that are routed to the upstream, intake end of the eulvert or the new downstream surface drain inlet. The house roof downspouts shall be connected into a closed pipe system that discharges directly in the new culvert pipe. Surface grading of the fill surfaee shall be conshucted so that the ground slopes down to the new intake structure from the upstream side of the surface "ridge" line, and toward the new surf�ce drain inlet, downstream from the "ridge" line. The ground surface shall be sloped at a minimum gradient of 5% away.from the "ridge" line. Water Summary: The project engineer notes that the seasonal stream on Uus properry flows down from the upper portion of the_ sij,�,.uuis adjacent to the house, and then to the existing headwall where it is pushed through an exis�g30�mch rein"i'orced concrete pipe and then back into a seasonal stream wlvch fluwt�iitto Easton C��eek. The drainage system in its current state has the capacity to cazry a 100-year storm wiWout impacting the upstream or downstream watercourse. The upsh�eam and downstream seasonal streazns have approximately 1.5 times We capacity of the 100-year storm. A sanitary sewer easement exists along the northwest side of the creek, between the house and the creelt A 6-inch diameter pipe is located in tivs easement. It extends in front of the garage and then follows the driveway down to Easton Drive. . Theproject consists ofextending an existing culvert for a distance of 82 feet. The project involvesremovingthe unstable materials in the stream channel; removing the headwall for We existing culvert, installing a new reinforced concrete pipe for a length of 82 feet and installing a new headwall and riprap at the entrance of the new culvert. The new fill added over the culvert would be stabilized with riprap, erosion control materials and landscaping. The proposed project consists of extending a pipe culvert upstream from the existing headwal� and hydraulically mimicking the existing condition. In addition, rock riprap would be placed up to the 100-year water svrface elevation along the proposed headwall and then 10-feet upstream to prevent scour and to pmvide a good 13 Initial Study Summary 2202 Summit Drive transitional azea, where the water would converge with the stream's critical water depth and have the ability to dissipate the hydranlic energy created when they converge. The impact will be negligible downstream because this pmject will not add any additional run-off to the drainage system. The proposed project will have no adverse impact on the existing drainage system. Public Works Engineering has reviewed the application for the impact of the enclosure on flow capacity of the creek, m�thods ofkeeping the shvchue clear of debris, the economic life and ease of repair of the enclosure, and the horizontal alignment of the culvert and the length of the culvert. The City Engineer has revi�wed the hydrologic calculations for the design and analysis provided by the project engineer and has determined that the project will not impact the flow of the creek.

Air Quality Summary: Site preparation and fill will be done during the dry season. No objectionable odors or alteration in air movement, moisture, tempeiature or change in local or regional climate is auticipated to occur as a result of tt►is proposal. T6e project will not result in an increase in traffic, and therefore will not have an affect on air quality based on vehicle emissions. Mitigation: -- -.- --�___The_site shall be.periodically sprayed with water to control dust during grading and construc6oa�. ■ Conshvction equipment emissions shall be urcompliance with the standards o€t�;e Bay.Area.Air Qua�lity _ Management District. Transportation/Circulation Summary: The proposed project will not result in additional residential development, and therefore will be no increase in traffic. Tl�ere will be no adverse impact on azea tcaffic or the street system. Biological Resources Summary: Since We project involves the culverting of an existing creek, it requires a Streambed Alterarion Permit &om the State Department of Fish and Game. Generally, the Department of Fish and Game encourages the protection of stream beds and discourages the removal of a piece ofnatu;ai landscape and topograPhY., 'Fhe applicant has submitted a Biological Survey of tl�e azea where the culvert would be extended to enclose the 82 feet of the open creek prepared by Thomas Reid Associates. The survey notes that the area of the drainage proposed to be culverted does not pmvide habitat for any sensitive species and no rare plant species were observed. Dominant plants found in the drainage include ivy, Califomia blackberry, poison .q�-maidenhair fern, bracken fern and coastal wood fetn. " •-� According to ihe biologist's report, the only expected impact of the pmject will be a warming and diying of the microclimate in the immediate vicinity ofthe creek associated with the placing of surface water in a pipe below ground. The survey points out that the drainage is already altered and does not provide habitat for s�nsitive species and that the project would not have a significant biological impacK. 'The biologist notes on a regional scale, tbe tFansformation ofmultiple natural features is IHcely to have biological impacts. He concludes that the contnbution of this individual project to any regional change is not measurable and is insignificant. 'I�vo exisking bay trees (28-inch and 48-inch circumference) wiil be removed as pazt of the projeck The. City Arborist noted that any trees of pmtected size (48-inch circumference or lazger) can only be removed witli appmval of a"protected tree removal" permit issued by the City. is Initial Study Summary Mitigation: 2202 Summit Drive Prior to any work in the creek bed, the applicant shall obtain a Streambed Alteration Permit from the State Department of Fish and Game. � Prior to any work in the creek bed, the applicant shall obtain a Protected Tree Removal Permit from the City of Burlingame for any trees 48-inches in circumference or lazger. Energy and Mineral Resonrces Summary: The amount of energy used to culvert the creek is negligi'ble. Substantial amounts of fuel will not be needed to .construct, develop or maintain the project. Hazards Summary: After construction this project will not be releasing any hazardous materials into the environment andwill noL interf'ere with any emergency response or evacuationplans the City ofBurlingamemay need to implement.-'I'here aze no l�own hea1W hazards on the site. This project is not expected to expo�e people ----to-health hazards, nor is.it expected to create a health hazard. _.. . . .� r . . . . . _ _ Noise Summary: The site is impacted by noise from t�affic on adjacent Easton, Summit and Canyon Drives and from air.craft landings and takeoffs at San Francisco Intemational Airporf, wluch is located about 2 1/2 miles northeast of the site. Cbnstruction activities may affect adjacent residences and the religious center; and noise levels may increase dnring construction. All construction must abide.by the construction hours established in the Municipal Code. Mitigation: ■ Unless no construction on days of religious meetings is requested by the nearby religiotts center, conshvction hours shall be limited to 7:00 a,m. to 7:00 p.m. weekdays, 8:00 a.m. to 6:00 p.m. SaUudays, and 10:Q0 a.m. to 6:00 p.m. on Sundays and holidays, per the requirements of the City of Burlingame Municipal Code. If requested conshvcdon shall not occur during times of scheduled religious mcetings.. Public Services Snmmary: Because the project represents no increase in the total population ofthe City and is located on an alrea�,�e�ped site, the existing public and governmental services in the.area have capacities wlrich cari''a�:'commodate the proposed culvert extension. It shall be the responsibility of tlie private property' owner to maintain the design flow capacity of the creek enclosiue. Utilities and Service Systems Snmmary: The propased project will be served by exisking utilities in place in � the azea, and once built will not consume additional utilities. � Aesthetics Snmmary: The project will result in the culverting of an existing open creek, with the cnlverted area covered with tr� shrubs and groundcover: Proposed trees include one, 24inch boX Japanese Maple tree; five, 5-gallon Tasmanian. tree feans; and six, 24-inch box Coast Live Oak irees. Proposed shrubs include Califomia Fescue grass, Douglas Iris, Red Fountain grass, Western Sword fern, Rhododendron; and Giant Cliain fem. Groundcover is also proposed and includes the following: R�Ianzanita GC, Evergeen Clematis and Dwarf Periwinkle. Cultural Resources Snmmary: The project consists of removing the unstable materials ut the stream channel and removing the headwall for the existing culvert. Any archeological, historic, culpual, or ethnic sites which �s Initial Study Summary 2202 Summit Drive may have been in or near these locations were disturbed or destroyed by previous development prior to this pmposal. Should any cultivai resources be discovered during construction, work will be balted until Wey aze fully investigated. Mitigation: • Should any culhual resources be discovered during construction, work shallbe halted until they aze fully investigated by a professional accepted as qualified by the City Planner and the recommendations of the expert have been executed to the satisfaction of the City. � Recreafion Summary: 'i'he proposed culvert extension does not replace or destroy any existing recreational facilities, nor does it displace any proposed or planned recreational. opportunities for the City of Burlingame. The site iwvolved in this project is not presentiy zoned or used for recreational uses. _ . ,.: Agriculturai Resotirces: There is no farmland orag�icultural reso�sces in Burlingame� Therefore, theproposed culvert extension will not convert farmland to a non-agricultural use or conflict with the zoning. SUMMARY OF MITIGATION MEASURES: A creek enclosure permit for the proposed culverting of a 82' section of the creek shall barequired before anyconstruction is allowed. 2. The condition of the existing sanitary sewer line should be investigated and repaired as necessary. 3. Work on the existing creek shall be performed only during the "dry" season (May through October) to reduce the potential for slope failures during the excavation work and the possible need for dewatering (in addition to the diveision of the creek flow). 4. A geotechnical engineer should be engaged during the work to observe the excavation cuts and provide advice ontb,e need for shoring o£the existing impre've��ats•ungl all the fill has been placed. � 5. The fill placement and compaction work shall be performed in a"dry" condition. 6. Removal oErceks, boulders, loose and unconfined soil and rock debris, vegetation, organic soils, and other debris and rubble from the creek bottom and sides shall be reviewed in the fieldby the project geoteclmical engineer at We time the work is in progess. 7. Portions of the existing rip rap shall be removed where it has been undermined. 8. Ground areas that are disturbed during thc clearing operation and other void or "hollow" areas sbali be pmperly backfilled. using the native soil and rock, or approved import soil, by compacting the backfill material to a Ivlinimum Relative Compaction of not less than 90% of the Maximum Dry.Density as determined by ASTM Test Prceedure D1557. 9. Native soils and rocks (acceptable for nse as fill material) and import fill material should be placed in layers, no thicker than 8 inches, moisture-conditioned, and compacted. �� Initial Study Summary 2202 SummitDrive 10. Prior to use on the site, all unport fill material shall be submitted ta the geotechnical engineer for inspection, testing (as necessary); and final approval for use on the site. 11. That the rip rap shall be underlain by a filter fabric to help reduce the potential for fuhue erosion and loss of the soil under the rip rap caused by water infiltration. 12. The surface of the new fill section should be provided with a means to *�;nim;�s erosion of the near-surface soils. 13. Existing surFace drain pipes shall be connected into new collector pipes tl�at aze routed to the upstream, intake end of the culvert or the new downstream surface drain inlet. 14. The house roof downspouts shall be connected into a closed pipe sysCem that discharges directly in the new culvert pipe. - J . - _ _ _ _ _ _._.::. . _ . . _ , I5. Surface grading of the fill surface. shali be constructed so that the ground slopes down to the new intake structure &om the upstream side of the surface "ridge" line, and towazd the new surface drain inlet, downstream from the "ridge" line. 'Fhe ground surface shall be sloped at a minimum gradient of 5% away from the "ridge" line. 16. All applicable requirements ofNPDES for runoffand drainage will be adhered to in the design and during construction. 17. The applicant shall submit a grading plan and erosion control plan for review and approval by the City Engineer. 18. T'he applicant shall submit an erosion and sedimentation control plan describing Best Management Practices (BMP's) to be used to prevent soil; dirt and debris from entering the storm drain system; the plan sbalI include a site plan showing the property lines, existing and proposed topography and slope; areas to �. :, _.. _ be disturbed, locations of cuUfill and soil storage/disposal azeas; azeas with existing v&gaM*'�_be-.. ' protected; existing and pmposed drainage pattern�and struchues; watercourse or �e�sitwaareas on-site or � immediately downstream of a project; and designated consiruction access routes, staging azeas andwashout areas. 19. Off-site runoffsha116e diverted around the conskuction site and all on-site runoffshall be diverted around ' exposed construction areas. 20. Methods and procedures such as.sediment basins or traps, earthen dikes or berms, silt fences, sdaw bale dikes, check dams storm drain inlet protection soil blanket or mats, and covers for soil stock piles to stabilize denuded areas shall be installed to maintain temporary erosion controls and sediment control continuously until permanent erosion controls have been established. �e Initial Study Su»rmary 2202 Summit Drive 2I. The erosion and sedimentation control plans should include notes, specifications, and/or attachments descnbing the construction operation and.maintenance of erosion and sediment control measums, mcludiug iuspection &equency; methods and schedule for grading, excavation, filling clearing of vegetative cover and mulch, including methods and schedules for planting and fertilization; and provisions for temporary and permanent imgation. 22. No velricles or equipment shall be cleaned, fueled or maintained on-site, except in designed areas where runoff is contained and treated. 23. All clearing limits, easements, setbacks, sensitive or critical azeas, buffer zones trees, and drainage courses are cleazly delineated with Seld mazkers or fencing and that adjacent properties and undisturbed azeas are protected &om construction impacts with vegetative buffer strips, sedimenE bazriers or filtecs, d7ces or mulching. =. � . . 24: Clearing; eaith moving achvities and the application of pesticides and fertilizers shalt be performed only during dry weather (April 15 through October 15)_ 25. If construcUon is done during the wet season (October 15 through Apri115), that prior to October 15 the developer shall implement a winterization program to minimize the potential for erosion and polluted runoffby inspecting, maintaining and cleaning all soil erosion and sed'unent conUrol prior to, during, and immediately after each storm even; stabilizing disturbed soils throughout temporary orpermanent seeding, mulching matting, or tarping; rocldng unpaved vehicle access to limit dispersion of mud onto public right- of-way; covering/tarping stored construction materials, fuels and other cbemicals. 26. The site shall be periodically sprayed with water to control dust during grading and construction. 27. Conshvction equipment emissions shall be in compliance with the standazds of the Bay Area Air Quality Management District 28. , P;ior to any w,^*k-�y�ek bed, the applicant shall ob.tain a Sh-eambed Alteration Permit &om the State Depaz+rneart o�Fis�i and Game: _ - * 29. Prior to any work in We creek bed, the applicant shall obtain a Protected Tree Removal Permit from the City of Burlingame for any trees.48-inches in circumference or larger. 30. Unless no construction on days of religioiLs meetings is requested by the nearby religious center; construction hours shall be lunited to 7:00 a.m. to 7:00 p.m. weekdays, 8:00 am. to 6:00 p.m. Sahudays, and 10:00 a.m. to 6:00 p.m. on Sundays and holidays, per the requirements of the City of Bwlingame Municipal Code.
