CONTRACT NO.: W912P7-06-D-0001

TASK ORDER: TBD

CONTRACTOR: Towill, Inc.

PROJECT: Comprehensive Evaluation of Project Datums (CEPD)

TITLE: ICW ARRA Funded Datums Evaluations

Page 2 of 79

1. General

The Comprehensive Evaluation of Project Datums (CEPD) is a USACE initiative that:

...describes specific procedural actions immediately required to evaluate the accuracy

and adequacy of existing flood protection elevations or controlling navigation depths

relative to federal datums established by the Department of Commerce and prescribed

for government-wide use by the Federal Geographic Data Committee (FGDC). This

guidance implements lessons learned from the Interagency Performance Evaluation

Task Force (IPET) study conducted after Hurricane Katrina, as identified in Volume

II (Geodetic Vertical and Water Level Datums) of the 1 June 2006 draft version of

the Final IPET Report-see https://ipet.wes.army.mil. It is specifically intended to

ensure that USACE project controlling elevations and datums are properly and

accurately referenced to nationwide spatial reference systems used by other Corps

Districts or Federal, state, and local agencies responsible for flood forecasting,

inundation modeling, flood insurance rate maps, bathymetric mapping, and

topographic mapping.

CEPD is a multi-step process involving 1) a Datums Evaluation Report, 2)

Implementation of Corrective Actions, and 3) updating the project design, if necessary.

Information on USACE requirements for CEPD can be found in EC 1110-2-6065,

Comprehensive Evaluation of Datums - Guidance for a Comprehensive Evaluation of

Vertical Datums on Flood Control, Shore Protection, Hurricane Protection, and

Navigation Projects

(2 April 2007) (http://140.194.76.129/publications/engcirculars/

ec1110-2-6065/toc.htm.) Additional guidance was recently provided in ER

1110-2-8160 Policies for Referencing Project Elevation Grades to Nationwide Vertical. http://140.194.76.129/publications/eng-regs/er1110-2-8160/toc.html.

Datums

This Scope of Work covers review of project documents and preparation of the Datums

Evaluation Report. Implementation of Corrective Actions and updating project design

are not included in this Task Order.

2. Obligation of Surveyor - Engineer (S-E)

The S-E will provide services and submittals as detailed in the following sections. It

shall be the S-E's responsibility to review all available USACE San Francisco District

documents to complete the Datums Evaluation Reports.

S-E shall notify TPOC as least 2 days prior to any site visit, so that appropriate building

security notifications can be made. S-E will have to follow standard building access

requirements during each visit (photo, badge, escort, etc).

S-E will need to visit both the USACE San Francisco District, San Francisco Office

(1455 Market St) and Sausalito Construction Office to review project files. It may also

be advantageous to visit Construction project field offices (xx). S-E may also wish to

contact project sponsors to obtain additional data, however USACE project manager must

be contacted and authorization to contact sponsors received on a project by project basis.

Page 3 of 79

S-E shall maintain a log of all contact with USACE personnel (other than TPOC) and

sponsors. If S-E does not receive a response from USACE personnel after 3 tries (at least

one of which should be in writing via email), TPOC shall be notified.

S-E shall not assume USACE copy machines are available. USACE copy machines are

not always operational or are in heavy use by USACE personnel, and S-E shall not claim

delays as a consequence. S-E may use USACE copy machines in Room 1585 as long as

no hardship is imposed on USACE personnel. Large format copier is also available in

Room 1551.

S-E shall catalog and identify physical location for all documents referenced and/or

removed from USACE offices and copy provided to TPOC after each visit. All reports,

maps, data and other information shall be returned to USACE office and replaced exactly

where borrowed from within one week of removal.

3. Obligation of the Government

Government TPOC will be available for guidance and comments on all work under this

contract. Any comments, advice and/or guidance given by the Government TPOC will

be to assist the S-E in performing the work and will not change this scope of services or

release the S-E from performing all work required unless written notification of such,

signed by the Contracting Officer or the CO's designated representative (COR).

For each project, TPOC shall provide the name and contact information for Project

Manager, Engineering Technical Lead (ETL) (if one exists) and Hydraulic Engineer (if

one exists). Many projects do not have an ETL or a Hydraulic Engineer. TPOC shall be

primary technical contact for projects where these do not exist. For GI-CG and O&M

projects - government will also provide information on project authorization,

appropriation and type of project. For FCCE projects, project authorization will need to

be identified by S-E, appropriation shall be identified as FCCE. See below for definitions

of project types.

4. Contractor Services

Tasks are defined based on groups of projects from various USACE programs. Project

groups have been setup almost solely for accounting (RFP) purposes. Once contract is

awarded priorities and S-E's preferred approach (geographic, etc) will be discussed at

kick-off meeting. Most likely the SPN priority shall be CG, GI, O&M, FCCE. But

District is also willing to be flexible if S-E considers an alternative approach to be more

efficient.

Projects are identified as either FCCE (Flood Control and Coastal Emergency), O&M

(Operation & Maintenance), GI (General Investigation), or CG (Construction General).

Projects designated here as Flood Control and Coastal Emergency (FCCE) are typically

Page 4 of 79

projects constructed by a non-federal sponsor, that have been found eligible to receive

federal assistance under Public Law 84-99, for disaster preparedness, emergency

operations and/or rehabilitation of flood control works. These projects must meet

specific federal requirements for maintenance and operation and are inspected biannually

by the USACE to verify continued eligibility. It is anticipated that S-E will

find very few supporting documents for FCCE projects.

GI and CG projects are part of the USACE Civil Works program. Typically GI projects

are in the study or design phase, while CG projects are in construction. However there

are also several CG projects at the San Francisco District that are in the study phase, but

because they are already constructed and in operation, they received CG funds and are

therefore referred to as CG projects even though, there is no currently on-going

construction. An example of this is the Sacramento Deep Water Ship Channel. It

currently has an operational depth of 30 feet MLLW, however there is an active study to

evaluate deepening the project to 35 feet MLLW or some intermediate increment.

O&M projects are projects where construction is complete and project is operated by the

USACE, such as many of our navigation projects.

The Contractor's services shall include the following items for all Tasks.

S-E will need to visit both the USACE San Francisco District, San Francisco Office

(1455 Market St., POC: Anne K Sturm) and Sausalito Construction Office to review

project files. It may also be advantageous to visit Construction project field offices. S-E

may also wish to contact project sponsors to obtain additional data, however USACE

project manager must be contacted and authorization to contact sponsors received on a

project by project basis. S-E shall maintain a log of all contact with USACE personnel

(other than TPOC) and sponsors. If S-E does not receive a response from USACE

personnel after 3 tries (at least one of which should be in writing via email), TPOC shall

be notified.

S-E shall notify TPOC as least 2 days prior to any visit to USACE offices, so that

appropriate building security notifications can be made. At 1455 Market St., S-E will

have to follow standard building access requirements during each visit (photo, badge,

escort, etc).

S-E shall catalog and identify physical location for all documents referenced and/or

removed from USACE offices and copy provided to TPOC after each visit. All reports,

maps, data and other information shall be returned to USACE office and replaced exactly

where borrowed from within one week of removal.

S-E shall complete the Comprehensive Evaluation of Project Datums (CEPD) Evaluation

Report for each project. Even when multiple projects appear to be part of the same

system, a separate report must be completed for each project. A template report and an

example of a completed report are included with this Scope of Work as Attachments 1

Page 5 of 79

and 2. All report sections shall be completed by S-E. The completed CEPD Evaluation

Report will be submitted to TPOC for review and approval.

Report shall assess the adequacy and accuracy of reference datums and survey control for

the subject project and meet the requirements of EC 1110-2-6065. The evaluation report

includes, but is not limited to, the following elements: identify and document all project

survey control monuments and benchmarks; document existing NSRS connections;

identify any legacy survey control (e.g. NAD27, NGVD29) and provide conversions

between legacy datums and NAVD88; and, document basis for all source hydraulic

elevations, including gages, and their survey control. If information is available, S-E

shall identify datums and elevation data used in hydrodynamic models. Project must

meet a relative and absolute vertical accuracy requirement of 0.25 feet. Though TPOC

may direct the use an alternate vertical accuracy on a project by project basis. Use of

Vertcon for datum conversions is not an acceptable option for either existing project

control or corrective action.

At a minimum, project must be referenced to the North American Datum 1983 (NAD83),

National Spatial Reference System (NSRS) 2007, epoch of 2007.00 or later, and the

North American Vertical Datum of 1988 ( NAVD88). Recommended geoid model shall

be GEOID09. GEOID09 release is expected by late September 2009. Any alternation of

this control shall be accompanied by an explanation from S-E.

Once a Draft Datums Evaluation Report is completed for a project, it shall be submitted

to TPOC for review. TPOC comments shall be provided to S-E within 2 weeks of receipt

of draft report. Teleconference may be held should the S-E have any questions regarding

comments. Final Datums Evaluation Report shall be submitted to TPOC two weeks after

receipt of comments.

This contract is being funded from the American Recovery and Reinvestment Act

(ARRA) (Stimulus) funds. Therefore Contractor must complete quarterly reporting

requirements as defined in Attachment 3. At the time with SOW is being issued,

reporting website is not yet active. TPOC will work with Contractor to fulfill reporting

requirements.

Task A: FCCE Group A

Task includes project review and completion of Datums Evaluation Report. See details

above. S-E shall assume 2 meetings - one kick-off meeting and one meeting following

completion of first few reports.

CAD and/or GIS files of the FCCE project alignments are available in various coordinate

systems. It should be noted that these are approximate alignments based on field

inspections. Any waypoints shown on figures are related to a specific inspection event

and not related to any project specific control.

56. Bay Farm Island Dike - Shore Protection (CG), Figure 26

Page 9 of 79

Shore Protection project located along the south side of San Leandro Channel and

San Leandro Bay between Bay Farm Island Bridge and the confluence of San

Leandro Channel and Airport Channel.

57. Corte Madera Creek - Flood Control Project, Figure 27

Corte Madera Creek and its tributaries drain an area of 28 square miles in Marin

County, California, and discharge into the west side of San Francisco Bay nine miles

north of the Golden Gate Bridge. The flood control project has been built in separate

units.

58. Estudillo Canal - Single Purpose Flood Risk Management, Figure 28

The study area is located within the City of San Leandro, California and about 15

miles southeast of San Francisco. The watershed drains into the San Francisco Bay,

with a drainage area of approximately 10 square miles. A substantial number of

properties within this densely populated area are designated as being in a Federal

Emergency Management Agency floodplain. The study will evaluate potential flood

damage reduction alternatives in a highly developed area.

59. Hamilton Airfield Wetland Restoration - Environmental Restoration (CG), Figure

29

The project site is located on San Pablo Bay, four miles east of the city of Novato, in

Marin County, California, and includes 988 acres of a former military airfield and

adjacent California State Lands Commission areas. The levee-protected site has

subsided below the elevation of surrounding properties, including the tidal wetlands

immediately adjacent to San Pablo Bay. This wetlands restoration project would

advance the beneficial reuse of dredge material from San Francisco Bay as part of the

Long Term Management Strategy (LTMS). The California State Coastal Conservancy

is the non-Federal sponsor.

60. Laguna de Santa Rosa - Environmental Restoration, Figure 30

The Laguna de Santa Rosa, a tributary of the Russian River, is located approximately

13 miles west of the city of Santa Rosa in Sonoma County, California. Historically,

this area has served as a naturally occurring 7,000-acre storm detention basin during

flooding of the Russian River, and is a valuable coastal fresh water wetland. The local

community believes that siltation has reduced the ability of the Laguna de Santa Rosa

to function as a major flood basin, and that thousands of acres of wetlands habitat

have been lost or degraded. Endangered species (steelhead trout and red-legged frogs)

are being negatively impacted due to this loss of habitat. The study will investigate

and evaluate solutions to the siltation problem in order to restore both the storm

detention function and wetland habitat of the area.

61. Larkspur Ferry Channel - Navigation (O&M) , Figure 31

This project consists of maintenance dredging of the main navigation channel to a

depth of -13 feet Mean Lower Low Water (MLLW) for a length of 13,560-feet and a

width of 232-feet wide, with a -15 feet MLLW Turning Basin at the channel

Page 10 of 79

terminal. The non-Federal sponsor, Golden Gate Bridge, Highway and Transportation

District, provides ferryboat transit service between Marin County and San Francisco.

62. Las Gallinas 205 - Flood Control (CG) , Figure 32

Las Gallinas Creek is located east of Highway 101 in the Santa Venetia area of Marin

County, about 10 miles north of San Francisco. Las Gallinas Creek is vulnerable to

extreme high tides and heavy storm runoff, and the existing levee system is

approaching the end of its useful life. A Section 205 flood damage reduction study

was initiated under the Continuing Authorities Program (CAP).

63. Napa River Salt Marsh - Environmental Restoration (CG) , Figure 33

This project is a shallow-draft channel, mainly light commercial and recreational

navigation. The operations and maintenance schedule provides for 6-year cycle

maintenance dredging for the Napa River Channel to -15 feet Mean Lower Low

Water (MLLW) from Mare Island Strait Causeway to Asylum Slough (down-stream

portion); thence -10 feet MLLW to head of navigation at the Third Street Bridge in

the City of Napa (up-stream portion). The project is approximately 16 miles long.

64. Ocean Beach - Shore Protection , Figure 34

Ocean Beach forms the western boundary of the City of San Francisco, California,

extending 3.3 miles along the Pacific Ocean coastline. The City of San Francisco, the

local sponsor, desires Corps assistance with developing and implementing a suitable

long-term coastal storm damage prevention plan. The beach itself is part of the larger

National Park Service Golden Gate National Recreation Area, and is recognized as a

uniquely valuable coastal resource within an urban environment. San Francisco

maintains municipal infrastructure on City property along the coastline, including the

Great Highway and the Lake Merced Sewage Transport Tunnel. The area falls within

the jurisdiction of the California Coastal Commission under the California Coastal

Act.

65. Oyster Point Harbor - Navigation (CG) , Figure 35

The City of South San Francisco owns Oyster Point Marina/Park, a 600-berth

recreational/commercial marina located adjacent to a variety of business parks,

including the headquarters for Genentech, approximately ten miles south of San

Francisco and two miles north of San Francisco International Airport. The 46-acre

facility includes picnic areas, jogging trails, a recreational fishing pier, bait shop,

small boat marine service and sales center, existing and proposed hotels, restaurants

and offices. Since 1977, the San Mateo County Harbor District has operated Oyster

Point Marina/Park under a Joint Powers Agreement with the City. A concrete

breakwater protects the Marina; however, there is a need to modify the entrance of

the harbor to provide safe navigation for current tenants of the marina, as well as

dinner cruise boats and a commuter ferry expected to begin operations in 2008. The

ferry is expected to provide NED benefits and reduce traffic and pollution impacts in

the Bay Area.

66. Pajaro River Watsonville - Single Purpose Flood Risk Management, Figure 36

Page 11 of 79

The existing flood damage reduction project, located in Santa Cruz and Monterey

Counties, California, consists of levees and channel improvements on the Pajaro

River and Corralitos and Salsipuedes Creeks constructed in 1949 to provide 50-year

flood protection to the Watsonville area. While the project remains capable of

successfully passing the flow rate it was originally designed for, the current level of

flood protection is about 8-15 years. This study will develop a locally acceptable plan

for flood protection features along the Pajaro River and Corralitos and Salsipuedes

Creeks in order to increase the level of flood protection afforded by the project.

67. Petaluma River - Flood Damage Reduction (CG) , Figure 37

The Petaluma River is located in Sonoma and Marin Counties, California on San

Pablo Bay. Project operations and maintenance provides for maintenance dredging of

a channel 200 feet wide and -8 feet deep across the flats in San Pablo Bay to the

mouth of the river; thence 100 feet wide and -8 feet deep to Western Avenue in

Petaluma, including a turning basin 300 to 400 feet wide and -8 feet deep. The City of

Petaluma is the local sponsor and is responsible for providing a suitable upland

disposal site.

68. Sacramento DWSC - Navigation (CG) , Figure 38

The Sacramento River Deep Water Ship Channel Project is a Congressionally

authorized project being implemented by the U.S. Army Corps of Engineers (Corps)

and the Port of Sacramento. Currently, the Corps and the Port of Sacramento are

conducting a Limited Reevaluation Study to recommend navigation improvements

for Federal funding and preparing a joint Supplemental Environmental Impact

Statement and Subsequent Environmental Impact Report (SEIS/SEIR) to evaluate the

action of resuming construction of navigational improvements to the Sacramento

River Deep Water Ship Channel (SRDWSC).

The SRDWSC runs from the Contra Costa county line to the Port of Sacramento. The

SRDWSC is located in the Sacramento - San Joaquin Delta region of northern

California. The 46.5-mile long ship channel lies within Contra Costa, Solano,

Sacramento, and Yolo Counties and serves the marine terminal facilities at the Port of

Sacramento. The SRDWSC joins the existing 35-feet deep channel at New York

Slough, thereby affording the Port of Sacramento access to San Francisco Bay Area

harbors and the Pacific Ocean.

69. San Pedro Creek, Pacifica - Flood Risk Management (CG) , Figure 39

San Pedro Creek lies in the Linda Mar area of Pacifica, California, along the Pacific

coast just south of San Francisco. The area has been subjected to severe damaging

floods, with approximately 100 acres subject to flooding. During the most recent

flood event in 1982, 183 residential and 10 commercial units suffered damages

exceeding $4 million. The project will use a floodwall plan and diversion-wetlandbypass

plan developed by the local sponsor as their preferred plan.

70. San Rafael Creek - Navigation, Figure 40

Page 12 of 79

San Rafael Creek is located north of San Francisco Bay in Marin County. This project

is a shallow-draft, mainly light commercial and recreational, channel. The operations

and maintenance schedule provides for 7 and 4-year cycle maintenance dredging,

respectively, for the Across the Flats Channel to -8 feet Mean Lower Low Water

(MLLW) in San Francisco Bay to the mouth of San Rafael Creek; thence -6 feet

MLLW for the Inner Canal Channel to the head of navigation at the Grand Street

Bridge in the City of San Rafael. The Across the Flats portion has always been

authorized for unconfined in-Bay aquatic disposal at site SF-11 south of Alcatraz

Island.

71. San Ramon Valley Recycled Water Project - Section 219 Environmental

Infrastructure (CG) , Figure 41

The project is located in the San Ramon Valley, approximately 25 miles east of San

Francisco, in the California counties of Contra Costa and Alameda. The project area

runs from Danville south to Dublin. The project will facilitate the use of recycled

water to replace potable water for landscape irrigation. The Corps' portion of this

project will include the design of one pump station and 6,500 feet of pipeline.

72. Santa Rosa Creek Ecosystem Restoration - Environmental Restoration, Figure 42

The Santa Rosa Creek watershed encompasses approximately 80 square miles,

including the City of Santa Rosa, in Sonoma County, California. Santa Rosa Creek, a

tributary to the Russian River, was channelized by the Soil Conservation Service in

the 1960s to provide flood control protection to the surrounding City of Santa Rosa.

The existing flood control structures have resulted in habitat loss. The sponsor

initiated this study in 1999 to restore the degraded areas and re-establish parts of the

creek as an area to restore salmonid spawning habitat. A draft hydrologic study,

completed in August 2002, concluded that the predicted one percent flows on the

Santa Rosa Creek significantly exceeds the current capacity of the existing flood

control structures. The sponsor has reviewed the Corps' Hydrologic study and has

requested that flood damage reduction measures be incorporated as a purpose of this

study.

73. SF Bay to Stockton - Navigation (CG) , Figure 43

The project consists of deep draft navigation channels, extending from the San

Francisco Bay entrance to the Port of Stockton, through San Francisco, Marin, Contra

Costa, Solano, Sacramento, and San Joaquin Counties. The Corps is assessing the

feasibility of deepening the existing 35-foot channel. The Port of Stockton is the non-

Federal sponsor for the study and Contra Costa County is a project partner.

74. Sonoma Creek & Tributaries - Environmental Restoration, Figure 44

The study area is located in Sonoma County, California. The Sonoma Creek

watershed drains a 170-square mile area into the northern reaches of the San

Francisco Bay estuary. This study was originally funded as part of the overall San

Pablo Bay Watershed Management Study as provided in the Energy & Water

Appropriations Act of 1998. The findings of this study indicate a Federal interest in

Page 13 of 79

providing solutions for environmental restoration and flood protection to Sonoma

Creek and its tributaries.

75. Upper Guadalupe River - Flood Damage Reduction (CG) , Figure 45

The Upper Guadalupe River study area is located in the City of San Jose, Santa Clara

County, California. The river reach proposed for this project begins at Interstate

Highway 280, at the edge of downtown San Jose, and extends south for

approximately 5.5 miles. The proposed project utilizes a combination of bypass

channels, floodwalls, and some channel widening to achieve flood damage reduction,

and is expected to aid the long term recovery of riparian forest habitat and salmonoid

migration.

Option Task D: GI_CG Group B

Task includes project review and completion of Datums Evaluation Report. See details

above.

76. Arroyo de la Laguna - Flood Damage Reduction & Environmental Restoration,

Figure 46

Arroyo de la Laguna is located in Alameda County, about 25 miles southeast of San

Francisco. Arroyo de la Laguna collects and drains runoff from Livermore, Dublin

and Pleasanton into Alameda Creek; a number of tributaries extend into Contra Costa

and Santa Clara Counties. The upper basin is approximately 15 miles wide, 45 miles

long and covers about 398,000 acres. The current Reconnaissance Study would

evaluate Federal interest in solutions to potential flooding and associated damage to

surrounding riparian habitat.

77. Bolinas Lagoon Restoration - Ecosystem Restoration, Figure 47

Bolinas Lagoon is a tidal embayment located 15 miles northwest of San Francisco, on

the Marin County coastline between the towns of Stinson Beach and Bolinas. The

lagoon is part of the Gulf of the Farallones National Marine Sanctuary managed by

the National Oceanic and Atmospheric Administration. Sedimentation in the lagoon

is causing a continuous loss of important subtidal and intertidal aquatic habitat,

resulting in a reduction of the diversity and abundance of aquatic life. The goal of the

environmental restoration effort is to ameliorate the adverse human impacts to

Bolinas Lagoon, thereby promoting the natural, dynamic processes of this

internationally-recognized estuarine environment. Although, over the long term,

sediment deposition will continue to fill the lagoon, the restoration project is intended

to significantly slow the present rate of intertidal and subtidal habitat loss.

78. FPMS San Mateo Co Levee Survey - Survey, Support to Others, Figure 48

Project would involve implementation of a USACE survey.

79. Pier 36 Removal - unknown (CG) , Figure 49

Page 14 of 79

80. Salt River Restoration - Ecosystem Restoration, CAP 206 (CG) , Figure 50

The Salt River is a tributary of the Eel River located near the town of Ferndale, in

Humboldt County, California. It originates in the Wildcat Mountains above Ferndale,

flows across the Eel River delta, and enters the Eel River within one mile of the

Pacific Ocean. This area lies in the 4th largest estuary in California and provides

habitat for two federally and state listed endangered species: the Brown Pelican and

Peregrine Falcon. The proposed Salt River Restoration Project is expected to restore

approximately two miles of riparian and wetland habitats along the Salt River, which

has been experiencing major ecosystem degradation due to sedimentation and

drainage problems. Project solutions under consideration include tide gate removal

and dredging to control excess sedimentation, and riparian restoration. The proposed

project is also expected to incidentally reduce future flooding and infrastructure

disasters. The non-Federal sponsor is the Humboldt County Resource Conservation

District (RCD).

81. San Francisco Bay Delta Model & Base Yard - Existing Infrastructure, Figure 51

San Francisco Bay Delta Model Regional Visitor Center is located in Sausalito,

California. The Center currently serves over 150,000 visitors annually, 60% of them

school children, fulfilling the Corps Strategic Communication goals, providing public

and curriculum-based school tours, special events, workshops, and seminars on the

Corps' modern missions within the context of the environmental, cultural, and

historical issues of the Bay Area. The center piece is a hydraulic scale model covering

one and one-half acres that was once used to reproduce existing and proposed

conditions of the San Francisco Bay and Estuary. Exhibits and programs explain

technical aspects of the model and the role of the Corps in water resource

developments in the Bay Area and throughout the Nation. The Regional Bay Model

Visitors Center works in cooperation with the Bay Model Association, which is a

non-profit organization. One of their main programs is the JASON project, which

provides school children scientific exploration of environments around the world

through video hookups at the Bay Model. Sponsors for this program include National

Geographic, NASA, and NOAA.

82. St Helena - Flood Risk Management and Environmental Restoration, Figure 52

The project is located approximately 60 miles north of San Francisco, in the City of

St. Helena, Napa County, California. The proposed project would provide rearing,

resident, and migratory habitats for Federally listed threatened and endangered

species and remove barriers to fish migration. The project would reconnect the Napa

River with restored aquatic, riparian and upstream habitat along the Napa River. The

City of St. Helena is the non-Federal Sponsor.

83. Upper Penitencia Creek - Single Purpose Flood Risk Management, Figure 53

Upper Penitencia Creek is located in the City of San Jose, in Santa Clara County,

California. The project is intended to reduce flood damages in San Jose and Milpitas.

Alternatives under consideration for this 3.6-mile reach include a combination of

flood-proofing at the upstream limit, levees, floodwalls and bypass channels.

Option Task E: GI_CG Group C

Task includes project review and completion of Datums Evaluation Report. See details

above.

Watershed studies are very general in nature and eventually lead to specific projects

within the watershed. The datums evaluation in this case must also be general,

identifying existing resources in the region and any shortcomings.

84. Arana Gulch Watershed - Watershed Study , Figure 54

This Ecosystem Restoration study was authorized by the House Transportation and

Infrastructure Committee Resolution dated June 25, 1999. The study area is located in

Santa Cruz County, California, adjacent to the Port of Santa Cruz. The study area

includes 2,200 acres of coastal watershed and seven miles of stream. The study will

involve a collaborative watershed planning effort to restore passage for endangered

anadromous fish, restore native riparian vegetation, improve water quality, improve

connectivity of the upper habitat, and reduce erosion and sedimentation throughout

the watershed. Additionally, the

beneficial use of sediment from the stream and harbor is being considered as part of a

Regional Sediment Management initiative.

85. Corte Madera Creek 209 - Watershed Study, Figure 55

The project study area is located in Marin County, California. Corte Madera Creek

and its tributaries drain an area of 28 square miles into the west side of San Francisco

Bay, nine miles north of the Golden Gate Bridge. This study will examine

improvements to stream function and flood damage reduction by exploring potential

physical and management measures including storm water management,

development, and sedimentation measures, as well as creek and habitat improvements

and maintenance. Local groups have requested a watershed study to examine

potential constructed and management improvements to the function of the

watershed, both to improve migration of the threatened Steelhead (et al) and reduce

flood damages.

86. Laguna Creek Watershed - Watershed Study, Figure 56

The study area is located within the City of Fremont, California about 28 miles

southeast of San Francisco. The watershed drains into the San Francisco Bay, with a

drainage area of approximately 25 square miles. This study will evaluate potential

flood damage reduction alternatives in a highly developed area.

87. Napa Valley Watershed Mgmt - Watershed Study, Figure 57

The Napa Valley Watershed is located within the northern portion of the San Pablo

Bay drainage basin in Napa County, California. The purpose of this study is to

complete a watershed analysis of the Napa River Watershed in order to address

watershed problems and opportunities through water and related land resource

management.

88. Pajaro River Basin Study - Watershed Study, Figure 58

This project is a watershed study centering on the Pajaro River, and includes the

California counties of Santa Clara, Santa Cruz, Monterey and San Benito. The study

will focus on flood protection, ecosystem restoration solutions and other purposes

such as recreation and water supply for the entire 12,000-square-mile watershed.

89. Russian River Watershed - Watershed Study, Figure 59

The Russian River Watershed encompasses 1,485 square miles (approx. 950,000

acres) within Sonoma and Mendocino Counties, California. This watershed study will

look at opportunities to prevent or reduce flood damages, to restore riverine

ecosystem values and the wise use of floodplains, to restore watershed functions

through restorative land-use practices, and to conserve remaining hydrologic and

ecological resources. The result of Phase I was the formation of the Russian River

Watershed Council, with the mission to protect, restore, and enhance the biological

health of the Russian River and its watershed through a community-based process,

facilitating communication and collaboration among all interested parties. The Plan of

Action for Phase II (POA) was also completed in Phase I. The POA articulates

critical issues and potential actions, and can be found at website

http://www.rrwc.net.

Phase II will include the completion of a Russian River

Watershed Adaptive Management Plan (WAMP).

90. San Pablo Bay Watershed, CA - Watershed Study, Figure 60

The San Pablo Bay Watershed Project addresses near, mid, and long-term restoration

and flood protection in the San Pablo Bay Watershed. The non-Federal sponsor for

the project is the State Coastal Conservancy. The San Pablo Bay Watershed is in the

northern reach of the San Francisco Estuary, an area whose population is projected to

increase by two million people during the next three decades. Innovative planning

and construction approaches can minimize the environmental impacts caused by this

growth and corresponding changes in land uses, including directing population and

land use changes away from critical resources such as wetland and riparian habitats.

The San Pablo Bay Watershed Restoration Program (Program) provides technical,

planning, and design assistance for restoration and flood protection in order to clarify

restoration parameters, goals, and objectives, and to identify and prioritize future

restoration opportunities. The technical, planning, and design assistance provided to

the Program supports resources protection for the construction of replacement

wetlands, protection from additional pollution, and creation of habitats to increase the

biodiversity and habitat values in the watershed.

91. Upper York Creek Dam - Aquatic Ecosystem Restoration, Figure 61

The project is located approximately 60 miles north of San Francisco, in the City of

St. Helena, Napa County, California. Upper York Creek Dam is an earthen dam built

around the turn of the 20th century. Its reservoir served as a water supply for the City

of St. Helena. The proposed project would create and restore approximately two acres

of channel, riparian, and upland habitat near the dam. It would also reconnect

approximately two miles of stream corridor habitat and associated upland habitat,

improving water quality and rearing, resident, and migratory habitats for Federally

Page 17 of 79

listed threatened and endangered species. The non-Federal project sponsor is the City

of St. Helena.
