DIGITAL FLOOD INSURANCE RATE MAP DATABASE, SANTA CLARA COUNTY, CALIFORNIA, USA
Dataset Identification:
Resource Abstract:
The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the
risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance
flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously
published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping
data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced
to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM
data files are consistent with those required for mapping at a scale of 1:12,000.

The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program
(NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection
Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or
by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities
located or to be located in identified areas having special flood hazards," Section 2 (b) (4) of the Flood Disaster Protection
Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are
the basis for the establishment of premium rates for flood coverage offered through the NFIP. The DFIRM Database presents
the flood risk information depicted on the FIRM in a digital format suitable for use in electronic mapping applications. The
DFIRM database is a subset of the Digital FIS database that serves to archive the information collected during the FIS.

Use Constraints: The hardcopy FIRM and DFIRM and the accompanying FISs are the official designation of SFHAs and Base Flood
Elevations (BFEs) for the NFIP. For the purposes of the NFIP, changes to the flood risk information published by FEMA may
only be performed by FEMA and through the mechanisms established in the NFIP regulations (44 CFR Parts 59-78). These digital
data are produced in conjunction with the hardcopy FIRMs and generally match the hardcopy map exactly. However the hardcopy
flood maps and flood profiles are the authoritative documents for the NFIP. Acknowledgement of FEMA would be appreciated in
products derived from these data.

The final product precision is computed by AirPhotoUSA's exclusive orthorectification software as a measure of the error between
the planimetric reference and the final orthorectified product. When the images are orthorectified all of the image pixels
are adjusted according to the computed orthorectification solution where the distortion from the camera and surface topography
is removed. Thus any vertical error that may exist in the DEM is dealt with in the orthorectification solution. As each image
is orthorectified the pixels at the original aerial triangulation measurements in each image are compared between the orthorectified
imagery and the planimetric reference in the orthorectification solution. A root mean squared residual is computed for each
measurement and combined to provide an RMSE for each image. These image RMSE's have been statistically combined to provide
one single RMSE for a project. Since the distortion due to the surface is removed during orthorectification there is no vertical
data in the final orthorectified product.

This data set contains digital ortho-imagery developed to support planning and delivery of USDA programs. The USDA field service
center use digital ortho imagery as a basic reference for conservation plans and soil survey. The imagery has a 1 meter ground
sample distance (GSD) ortho imagery rectified to National Mapping Standards at the 1:24,000 scale. Imagery is based on a (7.5
x 15) or (7.5 x11.25) minute quarter quadrangle with a 300 meter buffer on all four sides. Quarter quads imagery is formatted
to the UTM coordinate system using NAD83. Each quad may contain as much as 10% cloud cover per tile. This file was generated
by compressing quarter quadrangle tiles that cover a project area. MrSID compression, with mosaic option, was used. Target
values for the compression ratio are (15:1) and compression levels (9) are used. Imagery is used to meet USDA program requirements
including conservation planning and soil survey. The interim product is a compressed mosaic. Users should be aware that the
interim compressed mosaic may contain defects and have horizontal accuracy less than the specified tolerances.

The 'PLSS' layer is a polygon coverage depicting the township, range, and sections contained in the Public Land Survey System
grid for the State of California. Townships are roughly six miles aquare, and are numbered north and south from an established
baseline. Likewise, ranges are numbered east and west from an established meridian. California uses three baseline/meridians,
these being Humboldt, Mt. Diablo, and San Bernardino, abbreviated HB&M, MDB&M, and SBB&M. Township and range values are combined
in the redefined item TOWN-RANGE to facilitate dissolve and dropline functions.

Associates, for FEMA, under Contract No. H-4035. This work was completed in November 1978. Revisions to riverine flooding
adjacent to Coyote Creek in the vicinity of Nimitz Freeway (State Highway 17) between Montague Expressway and Dixon Road were
based on information obtained from a report dated October 11, 1983, prepared by the Santa Clara Valley Water District (SCVWD).
This study was revised April 15, 1988, to incorporate detailed flooding information from a report entitled, "Upper Penitencia
Creek Floodplain Management Study, Santa Clara County, California," dated February 1985. This report was prepared by the Natural
Resources Conservation Service (NRCS), Davis, California. Detailed flooding information from a report entitled "San Francisco
Bay Tidal Stage vs. Frequency Study," dated October 1984, and prepared by the San Francisco District of the U.S. Army Corps
of Engineers (USACE), was also incorporated in this revision. In addition, flooding from Line A - Zone 6 was updated to agree
with contiguous areas on the Flood Insurance Rate Map for the City of Fremont, California. This study was again revised on
June 8, 1998, to show modifications to the flooding along an approximately 1.5-mile reach of Berryessa Creek from the confluence
with Lower Penitencia Creek to the confluence with Arroyo De Los Coches, a 1.3-mile reach of Arroyo De Los Coches from the
confluence with Berryessa Creek to approximately 200 feet upstream of Piedmont Road, and a 1.4-mile reach of Calera Creek
from the confluence with Berryessa Creek to approximately 100 feet upstream of Old Piedmont Road. The hydrologic analysis
used in this study were performed by the SCVWD. The hydraulic analyses were conducted by Nolte and Associates Consulting Engineers,
for FEMA, under Contract No. EMW-90-C-3108.

In response to Procedure Memorandum (PM) 34 and 43 all levees within FEMA Region 9 will be identified and categorized. If
the levee is shown as protecting against the 1-percent-annual-chance flood, National Flood Insurance Program (NFIP) levee
certification will need to be verified, and the levee will be categorized according to the guidelines under PM 43. If NFIP
certification cannot be verified then the levee will be failed using approximate methodology.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction with the hardcopy
FEMA FIRM. The published effective FIRM and DFIRM are issued as the official designation of the SFHAs. As such they are adopted
by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions
exist in the regulations for public review, appeals and corrections of the flood risk information shown to better match real
world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain
boundaries is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data are
available in the Guidelines and Specifications for Flood Hazard Mapping Partners. Horizontal accuracy was tested by manual
comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system. Independent
quality control testing of FEMA?s DFIRM database was also performed.

Completeness Commission
evaluation Method Description
Data contained in the DFIRM Database files reflect the content of the source materials. Features may have been eliminated
or generalized on the source graphic, due to scale and legibility constraints. With new mapping, FEMA plans to maintain full
detail in the spatial data it produces. However, older information is often transferred from existing maps where some generalization
has taken place. Flood risk data are developed for communities participating in the NFIP for use in insurance rating and for
floodplain management. Flood hazard areas are determined using statistical analyses of records of river flow, storm tides,
and rainfall; information obtained through consultation with the communities; floodplain topographic surveys; and hydrological
and hydraulic analysis. Both detailed and approximate analyses are employed. Generally, detailed analyses are used to generate
flood risk data only for developed or developing areas of communities. For areas where little or no development is expected
to occur, FEMA uses approximate analyses to generate flood risk data. Typically, only drainage areas that are greater than
one square mile are studied.

ConceptualConsistency
measure Description
When FEMA revises an FIS, adjacent studies are checked to ensure agreement between flood elevations at the boundaries. Likewise
flood elevations at the confluence of streams studied independently are checked to ensure agreement at the confluence. The
FIRM and the FIS are developed together and care is taken to ensure that the elevations and other features shown on the flood
profiles in the FIS agree with the information shown on the FIRM. However, the elevations as shown on the FIRM are rounded
whole-foot elevations. They must be shown so that a profile recreated from the elevations on the FIRM will match the FIS profiles
within one half of one foot.
Data requests must include the full name of the community or county and the FIRM panel number(s) or the 7.5-minute series
quadrangle sheet area(s) covered by the request.
