culvert under U.S. Highway 101 and enters San Francisco Bay between Bair and Grecoislands. Stulsaft Branch and Jefferson Branch are labeled “Arroyo Ojo" on the USGS7.5 minute topographic map but are known as Stulsaft and Jefferson branches.

PROJECT DESCRIPTION

Under this Agreement, Permittee will conduct “routine maintenance activities”, asdescribed below, on Redwood Creek, and its tributaries, Kensington Branch, StulsaftBranch, Jefferson Branch and Emerald Branch. Routine maintenance activitiesauthorized under this Agreement shall be defined as those activities periodicallyscheduled and implemented as necessary to maintain water transport capacity andmaintain structural and functional integrity of existing concrete flood control channels.Routine maintenance activities described below are limited to the repair andrehabilitation of stormwater structures including trapezoidal and rectangular concretechannels and concrete culverts and other structures including trash racks and fenceposts within Redwood Creek and its tributaries. Exhibit B shows the amount of area tobe repaired for each category of activity described below. A total of approximately42,200 linear feet (8 miles) of creek will be maintained with approximately 12,000 linearfeet (2.2 miles) maintained per year. Routine maintenance activities will not beconducted in natural channels with natural bed and/or natural bank consisting of rock,gravel, vegetation and soil, and will not be conducted to the north of U.S. Highway 101.Specific routine maintenance activities include the following:

A. Repair Damaged Trash Rack: The trash rack will either be replaced in-kind orthe damaged rails repaired. This work will be implemented and outside of thetop-of-bank.

B. Repair Degraded Fencepost: Damaged portions of the concrete panel where thefence post is installed will be removed. New concrete will be cast in place withthe existing or new fence post and reinforced with a supplemental hairpin. Allwork will occur above the OHWM, however, workers may be required to accessthe worksite from a ladder placed within the channel bottom. The new concretewill be framed and cast in place. Once the concrete is dried the framing will beremoved.

C. Repair Spalling and Honeycomb Concrete on Panels and Inlets: Spallingconcrete is concrete that has broken up, flaked, or become pitted. Honeycombrefers to voids left in concrete due to failure of the mortar to effectively fill thespaces among coarse-aggregate particles. To repair areas identified withspalling or honeycomb concrete the damaged concrete will be removed using awire brush or sandblast to expose sound material. The exposed area will bepainted with a corrosion inhibitor and patched with a polymer modifiedcementitious mortar with aggregate. Work will be implemented using hand tools(e.g. wire brush, compressor and sandblast tool, ladder etc.). No heavyequipment will be placed within the channels.Repair sites below the OHWM or near the channel base will require temporary


dewatering. Approximately 5 linear feet and 5 square feet of spalling orhoneycomb repairs per each maintenance location will be required below theOHWM. The volume of fill material is based on the average depth of each repairtotaling 0.25 feet.

D. Repair Spalling and Corrosion (Below-Grade Culverts): The repair work willrequire reconstruction of the grating seats and inlets in general. To repair areasidentified with spalling or corrosion the damaged concrete will be removed usinga wire brush or sandblast to expose sound material. The exposed area will bepainted with a corrosion inhibitor and patched with a polymer modifiedcementitious mortar with aggregate. Work will be implemented using hand tools(e.g. wire brush, compressor and sandblast tool, ladder etc.). No heavyequipment will be placed within the channels. Approximately 5 linear feet and 5square feet of spalling or honeycomb repairs per maintenance location will berequired below the OHWM. The volume of fill material is based on the averagedepth of each repair totaling 0.25 feet.

E. Repair Soffit Missing Structural Concrete (Below-Grade Culverts): One areawithin a below-grade culvert near City Hall is missing structural concrete on thesoffit (Maintenance Location H11). In order to repair this section, this area willrequire infill of the missing soffits with a metal deck with concrete topping slab.Work will be implemented using crews with hand-tools (e.g. welding equipment,caulking gun, ladder, wire brush etc.) during low flow periods to minimize theneed to dewater. Although this work will be occurring on the ceiling well abovethe OHWM.

F. Repair Tapered Impact Deflector Panel at Culvert: Damage was found to atapered impact wall on the leading edge of the interior walls of a box culvert(Maintenance Location RW-305 & RW-050). To repair the deflector thedamaged portion will be removed as well as the existing channel invert slabapproximately one foot from the wall on each side. New concrete will be cast inplace and doweled into existing channel slab on each side. Work will beimplemented using hand tools (e.g. jackhammer, shovels, ladders, compressorsetc.). No heavy equipment will be placed within the culvert. The volume of fillmaterial is based on an average depth of 1 foot, length of 20 feet and height of 5feet to the OHWM.

G. Repair Transverse and Diagonal Panel Cracks and Longitudinal Cracks on baseof Rectangular & Trapezoidal Concrete Channel Structures: Cracks in theconcrete of widths between approximately 1/16-inch and %-inch wide will be filledwith an approved epoxy injection product. Work will be implemented using crewswith hand-tools (e.g. caulking gun, ladder, wire brush etc.) during low flowperiods to minimize the need to dewater. If dewatering is required for repairsalong the base, a cofferdam constructed of sandbags or other non-erodiblematerial will be temporarily placed upstream of the repair site. Approximately 10linear feet of cracks per maintenance location at an average width and depth of0.02 feet will occur below the OHWM.


H. Repair Transverse Cracks in Soffit (Below-Grade Culverts): Soffit refers to theceiling portion of the below-grade culvert. Cracks in the concrete of widthsbetween approximately 1/16-inch and %-inch wide shall be filled with anapproved epoxy injection product. Work will be implemented using crews withhand-tools (e.g. caulking gun, ladder, wire brush etc.) during low flow periods tominimize the need to dewater, This work will be occurring on the ceiling wellabove the OHWM.

I. Repair Out-of-Plane Offset on Wall of Trapezoidal-Concrete Channel Structure:The out-of-plane offset occurs where two panels meet and have become slightlyseparated over time. To repair the offset portions of concrete approximately 6inches to 12 inches from the offset on each side will be removed and replacedwith new concrete doweled into the existing channel slab and keyed with aflexible connection on the other side. Work will be implemented using hand tools(e.g. jackhammer, sledge hammer, shovels, ladders, compressors etc.). Noheavy equipment will be placed within the culvert. The volume of fill material isbased on an average depth of 1 foot, length of 1 foot and height of 5 feet fromthe base/bed to the OHWM.

J. Repair Out-of-Plane Offset on Wall of Rectangular-Concrete Channel: Torehabilitate the out-of-plane offset, rigid backing board and a waterproofmembrane will be placed behind the panel. To install the backing board, soilswill be excavated from behind the panel and backfilled once the backing boardand waterproof membrane is installed. Implementation will require working fromthe top of the bank and excavating behind the panel. Work for this repair will notbe conducted below the OHWM and will not result in fill.

K. Replace Trapezoidal-Concrete Channel Panel: The trapezoidal-concretechannel panels were constructed in approximately 30-foot-long-sections. Panelsections with excessive cracking and excessive offsets will be replaced in-kind.The concrete base will remain in place. Removal of the existing wall will requirethe use of heavy equipment such as a back hoe and/or jackhammer. Once thepanel is removed temporary shoring may be required where existing residentialproperties abut the top of the bank. Once the existing panel is removed a cast-in-place concrete panel on a shallow slab foundation will be installed. Acofferdam will be in place upstream of the work area. For each 30-foot section oftrapezoidal-concrete channel panel replaced, it is estimated that 15 cy ofconcrete will be required below the OWHM. A cofferdam will also be placeddownstream to prevent any water from permeating upstream into the work site.

L. Replace Rectangular-Concrete Channel Section: Rectangular-concrete channelsections were constructed in approximately 75 foot sections. Sections withexcessive cracking and excessive offsets will be replaced in-kind. Removal ofthe existing section will require the use of heavy equipment such as a back hoeand/or jackhammer. Once the section is removed, temporary shoring may berequired where existing residential properties abut the top of bank. Once theexisting section is completely removed cast-in-place rectangular-channel


sections will be installed. For each 75-foot section of rectangular-concrete panelreplaced it is estimated that 37.5 cy of concrete will be required below theOHWM. A cofferdam will be in place upstream of the work area. A cofferdamwill also be placed downstream to prevent any water from permeating upstreaminto the work site.

M. Trash cleanup: Removal of non-natural materials from the flood control channelswith hand tools including come-along cable pullers.

No heavyequipment shall be operated in other wetted areas such as ponds orwetlands without prior written approval from CDFW.


2.7 Tidallv Influenced Area. Work within any tidally influenced area shallbe completed at low tide periods only. All equipment shall be out ofthe channel prior to the incoming tide.

2.8 Concrete - Primary Containment. Permittee shall install thenecessary containment structures to control the placement of wetconcrete and to prevent it from entering into the stream channeloutside of those structures. No concrete shall be poured within thehigh flow line if the 15-day weather forecast indicates any chance ofrain.

2.9 Concrete -Designated Monitor. At all times when Permittee ispouring or working with wet concrete, there shall be a designatedmonitor to inspect the containment structures and ensure that noconcrete or other debris enters into the channel outside of thosestructures. Runoff from the concrete shall not be allowed to enterthe stream channel at any time.

2.10 Isolate Poured Concrete for 30 Days. If feasible, poured concreteshall be excluded from the wetted channel for a period of 30 daysafter it is poured. During that time the poured concrete shall be keptmoist, and runoff from the concrete shall not be allowed to enter alive stream. CDFW-approved commercial sealants may be appliedto the poured concrete surface where difficulty in excluding waterflow for a long period may occur. If sealant is used, water shall beexcluded from the site until the sealant is dry.

2.11 Concrete Curing Alternative. If rain does occur after pouring orconcrete cannot be excluded from the wetted channel for a period of30 days, the Permittee shall monitor the pH of any water that hascome into contact with the poured concrete. If this water has a pH of9.0 or greater, the water shall be pumped to a tanker truck or to alined off-channel basin and allowed to evaporate or be transported toan appropriate facility for disposal. During the pH monitoring period,all water that has come in contact with poured concrete shall beisolated and not allowed to enter the water or otherwise come incontact with fish and other aquatic resources. The water shall beretested until pH values become less than 9.0. Once this has beendetermined, the area no longer needs to be isolated. Results of pHmonitoring shall be made available to CDFW upon request. A non¬toxic substance that can buffer the pH shall be made available onsite to use if any contamination to water occurs.

2.12 CDFW-Approved Qualified Biologist(s) and Biological Monitor(s).Within a minimum of 30 days prior to initiating species surveys withinthe Project area, Permittee shall submit to CDFW for approval, the


names and resumes of all qualified biologists and biological monitorsinvolved in conducting surveys and/or monitoring work.

A qualified biologist is an individual who shall have a minimum of fiveyears of academic training and professional experience in biologicalsciences and related resource management activities, with aminimum of two survey seasons years (for e.g. two seasons duringthe blooming season of sensitive plants) conducting surveys foreach species that may be present within the Project area.

A biological monitor is an individual who shall have academic andprofessional experience in biological sciences and related resourcemanagement activities as it pertains to this Project, experience withconstruction-level biological monitoring, be able to recognize speciesthat may be present within the Project area, and be familiar with thehabits and behavior of those species.

2.13 Designation of Work Area. Prior to maintenance activities in naturalcreeks or where access may occur near riparian vegetation, abiological monitor or qualified biologist shall clearly mark/flag or erecttemporary construction fencing to designate the work area and todelineate the areas that shall be avoided. In the concrete linedchannels, the contractor can clearly mark the project areaboundaries. The boundaries shall be inspected on a regular basis toensure that work has remained within the marked boundaries. If oneor more boundary(ies) has/have been violated, work shall cease untilPermittee has taken appropriate action to ensure there is norecurrence of the trespass. Flagging and/ or temporary constructionfencing shall be removed immediately after the completion ofconstruction work.

2.14 Narrow Width Trail. Where necessary, Permittee may clear a narrowwidth trail to provide vehicular access to a work site. Vegetationremoval shall be limited to the minimum amount necessary toprovide access.

Coffer dams shall be constructed of a non-erodible materialwhich does not contain soil or fine sediment. Coffer dams and thestream diversion system shall remain in place and functionalthroughout the construction period. If the coffer dams or streamdiversion fail, they shall be repaired immediately. Normal flows shallbe restored to the affected stream immediately upon completion ofwork at that location. As an alternative for portions of the channelthat contain small isolated ponded areas and/or where a coffer damis not practicable, the Permittee may deploy tarps or catchmentdevices, around the concrete removal and repair sites to prevent anydebris or concrete shavings from entering the ponded area. Pumpsmay be used to pump isolated ponded water away from the workzone to pump water downstream when using a cofferdam. A smallpump can be used to remove any small puddles or areas of nuisancewater No other diversion method shall be used without authorizationof CDFW. If another diversion method is preferred, the Permitteemust submit a plan detailing the desired diversion method.Authorization of any other diversion method shall be at the discretionof CDFW.

2.19 Check for Stranded Aquatic Life. The biological monitor or qualifiedbiologist shall check daily for stranded aquatic life as the water levelin the dewatering area drops. All reasonable efforts shall be made tocapture and move all stranded aquatic life observed in the dewateredareas. Capture methods may include fish landing nets, dip nets,buckets and by hand. Captured aquatic life shall be releasedimmediately in the closest body of water adjacent to the work site.This measure does not allow for the take or disturbance of any stateor federally listed species.

2.20 Catchment Devices. When working above OHWM, the Permitteeshall deploy tarps or catchment devices, around the concrete


removal and repair sites to prevent any debris or concrete shavingsfrom entering the creek whether the site is dewatered or not. Thesedevices shall be maintained throughout all phases of the excavationand construction activities.

2.21 Spoils. Concrete, debris or other construction material shall not beplaced where it could enter the stream. Spoils shall not be placedover riparian or wetland vegetation except as specifically noticed toand accepted by CDFW.

2.22 Removal of Trash and Debris. Permittee shall remove all rawconstruction materials and wastes from work sites following thecompletion of maintenance activities. Food-contaminated wastesgenerated during work shall be removed on a daily basis to avoidattracting predators to work sites. All temporary fences, barriers,and/or flagging shall be completely removed from work sites andproperly disposed of upon completion of maintenance activities.Permittee or its contractors shall not dump any litter or constructiondebris within the riparian/stream zone.

2.23 Staging and Storage Areas. Building materials and/or constructionequipment shall not be stockpiled or stored where they could bewashed into the water or where they will cover aquatic or riparianvegetation.

2.24 Equipment over Drip-pans. Staging and storage areas forequipment, materials, fuels, lubricants and solvents shall be locatedaway from the wetted areas. Stationary equipment such as motors,pumps, generators, compressors and welders, located within oradjacent to the creek shall be positioned over drip-pans.

2.25 Maintenance of Vehicles. Any equipment or vehicles driven and/oroperated adjacent to the creek areas shall be checked andmaintained daily to prevent leaks of materials that if introduced towater could be deleterious to aquatic life, wildlife or riparian habitat.Vehicles must be moved away from the stream prior to refueling andlubrication.

2.26 Hazardous Materials. Debris, soil, silt, bark, slash, sawdust, rubbish,creosote-treated wood, raw cement/concrete or washings thereof,asphalt, paint or other coating material, oil or other petroleumproducts, or any other substances which could be hazardous toaquatic life, wildlife, or riparian habitat resulting from the projectrelated activities shall be prevented from contaminating the soiland/or entering the waters of the State.


2.27 Spill Cleanup. Permittee shall begin the cleanup of all spillsimmediately. CDFW shall be notified immediately by the Permitteeof any spills and shall be consulted regarding cleanup procedures.The Permittee shall have all spill clean-up equipment on site duringconstruction.

2.28 Spill Containment. All activities performed in or near a stream shallhave absorbent materials designated for spill containment and clean¬up activities on-site for use in an accidental spill. The Permittee shallimmediately notify the California Emergency Management Agency at1-800-852-7550 and immediately initiate the clean-up activities.CDFW shall be notified by the Permittee and consulted regardingclean-up procedures.

2.29 Debris and Waste Disposal. The contractor shall not dump any litteror construction debris within the project area. Ail such debris andwaste shall be picked up daily and properly disposed of at anappropriate site.

2.30 Change of Conditions. If, in the opinion of CDFW, conditions arise,or change, in such a manner as to be considered deleterious to thestream or wildlife, operations shall cease until corrective measuresapproved by CDFW are taken.

Species Avoidance Measures

Raptors, Birds and Bats

2.31 Nesting Bird Survey. For maintenance activities requiring heavyequipment scheduled during the nesting season of raptors andmigratory birds, a focused survey for active nests of such birds shallbe conducted by the qualified biologist within 15 days prior to thebeginning of project-related activities. Surveys shall be conducted inall suitable habitat located at project work sites and in staging andstorage areas. The minimum survey radii surrounding the work areashall be the following: i) 250 feet for passerines; ii) 500 feet for othersmall raptors such as accipiters; iii) 1,000 feet for larger raptors suchas buteos. The bird survey methodology and the results of thesurvey shall be submitted to the CDFW prior to commencement ofProject activities.

Nesting seasons shall be defined as followed: i) March 15 to August30 for smaller bird species such as passerines; ii) February 15 toAugust 30 for raptors.


2.32 Active Nests. If active nests are found, the Permittee shall consultwith the CDFW and the USFWS regarding appropriate action tocomply with the Migratory Bird Treaty Act of 1918 and the FGC. If alapse in project-related work of 15 days or longer occurs, anotherfocused survey shall be conducted before project work is reinitiated.If active nests are found, the Permittee shall consult with the CDFWand the USFWS prior to resumption of project activities.

2.33 Active Nest Buffers. Active nest sites shall be designated as“Ecologically Sensitive Areas" and protected (while occupied) duringproject activities with the establishment of a fence barriersurrounding the nest site. The minimum distances of the protectivebuffers surrounding each identified nest site shall be the following: i)500 feet for large raptors such as buteos; ii) 250 feet for smallraptors such as accipiters; iii) 250 feet for passerines. A biologicalmonitor or qualified biologist shall monitor the behavior of the birds(adults and young, when present) at the nest site to ensure that theyare not disturbed by project-related activities. Nest monitoring shallcontinue during project-related construction work until the younghave fully fledged, are no longer being fed by the parents and haveleft the nest site, as determined by a biological monitor.

2.34 Nesting Habitat Removal or Modification. No trees or shrubs shallbe disturbed that contain active bird nests until all eggs havehatched, and young have fully fledged (are no longer being fed bythe adults, and have completely left the nest site). To avoid potentialimpacts to tree or shrub-nesting birds, any trimming or pruning oftrees or shrubs shall be conducted during the time period ofSeptember 16 to February 14. No habitat removal or modificationshall occur within the Ecologically Sensitive Area fenced nest zoneeven if the nest continues to be active beyond the typical nestingseason for the species (refer to Measure 2.31), until the young havefully fledged and will no longer be adversely affected by the project.

2.35 Bat Avoidance. The qualified biologist shall conduct a habitatassessment for bats at work sites where culverts, bridges andstructures would be disturbed. The habitat assessment shall includea visual inspection of features within 50 feet of the work area forpotential roosting features (bats need not be present) no more than48 hours prior to disturbance of such features. Habitat features foundduring the survey shall be flagged or marked. If bat habitat isdetected during the habitat assessment, CDFW shall be notifiedimmediately. CDFW reserves the right to provide additionalprovisions to this agreement in the event that roosting bats arefound. Permittee shall not attempt to directly disturb (e.g. shake,prod) roosting features


2.36 Stop Work Authority. The biological monitors or qualified biologistshall have the responsibility and authority of stopping the proposedproject if any crews or personnel are not complying with theprovisions outlined in this Agreement.

- Include any structures (e.g., rip-rap, culverts, or channel clearing) that will be placed, built, or completed in or nearthe stream, river, or lake.

- Specify the type and volume of materials that will be used.- If water will be diverted or drafted, specify the purpose or use.Enclose diagrams, drawings, plans, and/or maps that provide all of the following: site specific construction details; thedimensions of each structure and/or extent of each activity in the bed, channel, bank or floodplain; an overview of theentire project area (i.e., “bird's-eye view”) showing the location of each structure and/or activity, significant areafeatures, and where the equipment/machinery will enter and exit the project area.

Below is a summary of Project maintenance activities.

The City of Redwood City contracted with an engineering firm to document deficiencies of structureswithin Redwood Creek and its tributaries. The engineering firm documented deficiencies withinrectangular-concrete channel structures, trapezoidal-concrete channels, below-grade concreteculverts (e.g. underground box culverts), and at points between differing types of structures referred toin this report as “transitions points”.

Refer to the USACE PCN, Section 2.4 (Attachment 2 CD) for a discussion of typical deficienciesfound within the structures and a description of how they would be repaired and/or rehabilitated.Included in the USACE PCN, Table 1 lists the type of repair and linear distance and cubic yard of fillmaterial. For a detailed list of repairs, maintenance location designation and photograph designationrefer to Exhibit 2. Photographs associated with the repairs can be found in Exhibit 3 and a mapshowing the location of each repair can be found in Exhibit 1.

Refer to the Exhibit 4 USACE PCN, Section 2.7 and Table 1 for the types of material beingdischarged, the amount of each type in cubic yards, and linear feet.

12. MEASURES TO PROTECT FISH, WILDIFE, AND PLANT RESOURCES_A. Describe the techniques that will be used to prevent sediment from entering watercourses during and after construction.

Refer to USACE PCN, Section 4.0 for measures that will be implemented to prevent sediment andother pollutants from entering the watercourse. In addition, San Mateo County’s Construction BestManagement Practices as it applies to the proposed Project, will be implemented (refer to Attachment2, USACE PCN for a list of BMPs).


B. Describe project avoidance and/or minimization measures to protect fish, wildlife, and plant resources.

All maintenance work will be limited to the concrete channels to avoid impacts to water quality andaquatic resources (e.g. invertebrates, vegetation etc.). During the late spring, summer, and early fallthe concrete channels are either dry or have minimal nuisance water (urban runoff) flowing throughthem. It is very unlikely that fish could access the concrete channels during the late spring, summer,and early fall due to the lack of water flow within the concrete channels.

Refer to USACE PCN, Section 4.0 for avoidance and minimization measures.

___ _ □Continued on additional page(s)

C. Describe any project mitigation and/or compensation measures to protect fish, wildlife, and plant resources.

From Bradford Street, for approximately six City blocks, Redwood Creek flows underground in aconcrete box culvert (refer to USACE PCN Figure 4) which acts as a barrier or impediment to fishmigration upstream. Additionally, spawning habitat is not available and foraging habitat is marginal.During the late spring, summer, and early fall the concrete channels are either dry or have minimalnuisance water (overflow from lawn watering, car washing on street, etc.) flowing through them. It isvery unlikely that fish could access the concrete channels during the late spring, summer, and earlyfall due to the lack of water flow within the concrete channels and underground barriers. Therefore,with the implementation of the avoidance, minimization and BMPs, mitigation is not warranted.
