STATE LOCAL CONSIDERATIONS
This document provides the Federal Emergency Management Agency's determination regarding a request for a Letter of Map Amendment for
the property described above. Using the information submitted and the effective National Flood Insurance Program (NFIP) map, we have
determined that the property(ies) is/are not located in the SFHA, an area inundated by the flood having a 1-percent chance of being equaled or
exceeded in any given year (base flood). This document amends the effective NFIP map to remove the subject property from the SFHA located
on the effective NFIP map; therefore, the Federal mandatory flood insurance requirement does not apply. However, the lender has the option to
continue the flood insurance requirement to protect its financial risk on the loan. A Preferred Risk Policy (PRP) is available for buildings located
outside the SFHA. Information about the PRP and how one can apply is enclosed.
This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this
determination. If you have any questions about this document, please contact the FEMA Map Information eXchange (FMIX) toll free at (877)
336-2627 (877-FEMA MAP) or by letter addressed to the Federal Emergency Management Agency, Engineering Library, 3601 Eisenhower Ave

ADDITIONAL INFORMATION REGARDING
LETTERS OF MAP AMENDMENT
When making determinations on requests for Letters of Map Amendment (LOMAs), the Department of
Homeland Security’s Federal Emergency Management Agency (FEMA) bases its determination on the
flood hazard information available at the time of the determination. Requesters should be aware that flood
conditions may change or new information may be generated that would supersede FEMA's determination.
In such cases, the community will be informed by letter.
Requesters also should be aware that removal of a property (parcel of land or structure) from the Special
Flood Hazard Area (SFHA) means FEMA has determined the property is not subject to inundation by the
flood having a 1-percent chance of being equaled or exceeded in any given year (base flood). This does not
mean the property is not subject to other flood hazards. The property could be inundated by a flood with a
magnitude greater than the base flood or by localized flooding not shown on the effective National Flood
Insurance Program (NFIP) map.
The effect of a LOMA is it removes the Federal requirement for the lender to require flood insurance
coverage for the property described. The LOMA is not a waiver of the condition that the property owner
maintain flood insurance coverage for the property. Only the lender can waive the flood insurance purchase
requirement because the lender imposed the requirement. The property owner must request and receive a
written waiver from the lender before canceling the policy. The lender may determine, on its own as a
business decision, that it wishes to continue the flood insurance requirement to protect its financial risk on
the loan.
The LOMA provides FEMA's comment on the mandatory flood insurance requirements of the NFIP as they
apply to a particular property. A LOMA is not a building permit, nor should it be construed as such. Any
development, new construction, or substantial improvement of a property impacted by a LOMA must
comply with all applicable State and local criteria and other Federal criteria.
If a lender releases a property owner from the flood insurance requirement, and the property owner decides
to cancel the policy and seek a refund, the NFIP will refund the premium paid for the current policy year,
provided that no claim is pending or has been paid on the policy during the current policy year. The
property owner must provide a written waiver of the insurance requirement from the lender to the property
insurance agent or company servicing his or her policy. The agent or company will then process the refund
request.
Even though structures are not located in an SFHA, as mentioned above, they could be flooded by a flooding
event with a greater magnitude than the base flood. In fact, more than 25 percent of all claims paid by the
NFIP are for policies for structures located outside the SFHA in Zones B, C, X (shaded), or X (unshaded).
More than one-fourth of all policies purchased under the NFIP protect structures located in these zones.
The risk to structures located outside SFHAs is just not as great as the risk to structures located in SFHAs.
Finally, approximately 90 percent of all federally declared disasters are caused by flooding, and homeowners
insurance does not provide financial protection from this flooding. Therefore, FEMA encourages the
widest possible coverage under the NFIP.
LOMAENC-1 (LOMA Removal)
The NFIP offers two types of flood insurance policies to property owners: the low-cost Preferred Risk
Policy (PRP) and the Standard Flood Insurance Policy (SFIP). The PRP is available for 1- to 4-family
residential structures located outside the SFHA with little or no loss history. The PRP is available for
townhouse/rowhouse-type structures, but is not available for other types of condominium units. The SFIP is
available for all other structures. Additional information on the PRP and how a property owner can quality
for this type of policy may be obtained by calling the Flood Insurance Information Hotline, toll free, at 1-800-
427-4661. Before making a final decision about flood insurance coverage, FEMA strongly encourages
property owners to discuss their individual flood risk situations and insurance needs with an insurance agent
or company.
FEMA has established "Grandfather" rules to benefit flood insurance policyholders who have maintained
continuous coverage. Property owners may wish to note also that, if they live outside but on the fringe of the
SFHA shown on an effective NFIP map and the map is revised to expand the SFHA to include their
structure(s), their flood insurance policy rates will not increase as long as the coverage for the affected
structure(s) has been continuous. Property owners would continue to receive the lower insurance policy
rates.
LOMAs are based on minimum criteria established by the NFIP. State, county, and community officials,
based on knowledge of local conditions and in the interest of safety, may set higher standards for
construction in the SFHA. If a State, county, or community has adopted more restrictive and comprehensive
floodplain management criteria, these criteria take precedence over the minimum Federal criteria.
In accordance with regulations adopted by the community when it made application to join the NFIP, letters
issued to amend an NFIP map must be attached to the community's official record copy of the map. That
map is available for public inspection at the community's official map repository. Therefore, FEMA sends
copies of all such letters to the affected community's official map repository.
When a restudy is undertaken, or when a sufficient number of revisions or amendments occur on particular
map panels, FEMA initiates the printing and distribution process for the affected panels. FEMA notifies
community officials in writing when affected map panels are being physically revised and distributed. In
such cases, FEMA attempts to reflect the results of the LOMA on the new map panel. If the results of
particular LOMAs cannot be reflected on the new map panel because of scale limitations, FEMA notifies the
community in writing and revalidates the LOMAs in that letter. LOMAs revalidated in this way usually will
become effective 1 day after the effective date of the revised map.

1. INTRODUCTION
This Letter of Map Amendment (LOMA) has been prepared in order to certify that the existing
property within the Nakano project in the City of Chula Vista, California is above the flood
elevations as indicated on the NFIP map.
The purpose of the application is to demonstrate that the existing elevations of the Nakano property
are above the flood elevations indicated by Zone AE as shown in the FIRM Panel No.
06073C2158G, effective date May 16, 2012. The Zone AE floodplain extends along the north
portion of the site with water surface elevations ranging from 83.8 to 92.7 ft. MSL (NGVD 29).
Note that there a 2.17 conversion from NAVD88 to NGVD29 datum. The elevations listed on the
exhibit show elevations per the NGVD29 datum.
2. SUMMARY OF METHODOLOGY
The following summarizes how the base flood elevations were determined in order to ensure the
existing elevations are above the base flood and enable their removal from the special flood hazard
area mapping.
2.1 Existing Condition of the Property
The Nakano site consists of approximately 23.8 acres of existing hillside and grass land use located
within the Otay Mesa neighborhood of the City of Chula Vista. The site is bounded by Kaiser
Permanente medical offices to the South, Interstate 805 to the West, an existing residential site to
the east and Otay River to the North. Existing condition onsite includes grassland, hillside, utilities
facilities, and a small dirt paths traversing the property.
Per the FIRM panel, in the existing condition, the floodplain encroaches into the site along the
northern extents of the project boundary. Along the northern portion of the property the site is
affected by Zone AE. Refer to Exhibit A-1 for the existing floodplain exhibit depicting the
relationship of the floodplain to the property.

2.2 Floodplain Base Flood Elevation Comparison
The base flood elevations (BFE) were taken from the FEMA FIRM Panel No. 06073C2158G,
effective date May 16, 2012. The Zone AE floodplain extends along the north portion of the site
with water surface elevations ranging from 83.8 to 92.7 ft. MSL (NGVD 29). The lowest point on
the site along the northern property line is 95.7, three feet above the highest floodplain elevation
at the northwest corner of the site of 92.7. This comparison of the worst case scenario of the lowest
elevation on the existing property is still three feet higher than the highest floodway elevation at
any point on site indicates that the entire site can be removed from the special flood hazard area
mapping.
3. CONCLUSIONS
The existing property elevations indicate that the entire site is higher than the determined Zone AE
special flood hazard area base flood elevations for the Otay River. Therefore, this report supports
a recommendation that the entire property identified be removed from the 100-year floodplain
limits.

form to this address.
This form may be completed by the property owner, property owner’s agent, licensed land surveyor, or registered professional engineer to support a request for a
Letter of Map Amendment (LOMA), Conditional Letter of Map Amendment (CLOMA), Letter of Map Revision Based on Fill (LOMR-F), or Conditional Letter of Map
Revision Based on Fill (CLOMR-F) for existing or proposed, single or multiple lots/structures. In order to process your request, all information on this form must be
completed in its entirety, unless stated as optional. Incomplete submissions will result in processing delays. Please check the item below that describes your request:
LOMA A letter from DHS-FEMA stating that an existing structure or parcel of land that has not been elevated
by fill (natural grade) would not be inundated by the base flood.
CLOMA A letter from DHS-FEMA stating that a proposed structure that is not to be elevated by fill (natural
grade) would not be inundated by the base flood if built as proposed.
LOMR-F A letter from DHS-FEMA stating that an existing structure or parcel of land that has been elevated by
fill would not be inundated by the base flood.
CLOMR-F A letter from DHS-FEMA stating that a parcel of land or proposed structure that will be elevated by fill
would not be inundated by the base flood if fill is placed on the parcel as proposed or the structure is
built as proposed.
Fill is defined as material from any source (including the subject property) placed that raises the ground to or above the Base Flood Elevation (BFE). The common
construction practice of removing unsuitable existing material (topsoil) and backfilling with select structural material is not considered the placement of fill if the
practice does not alter the existing (natural grade) elevation, which is at or above the BFE. Fill that is placed before the date of the first National Flood Insurance
Program (NFIP) map showing the area in a Special Flood Hazard Area (SFHA) is considered natural grade.

STATE LOCAL CONSIDERATIONS
This document provides the Federal Emergency Management Agency's determination regarding a request for a Letter of Map Amendment for
the property described above. Using the information submitted and the effective National Flood Insurance Program (NFIP) map, we have
determined that the property(ies) is/are not located in the SFHA, an area inundated by the flood having a 1-percent chance of being equaled or
exceeded in any given year (base flood). This document amends the effective NFIP map to remove the subject property from the SFHA located
on the effective NFIP map; therefore, the Federal mandatory flood insurance requirement does not apply. However, the lender has the option to
continue the flood insurance requirement to protect its financial risk on the loan. A Preferred Risk Policy (PRP) is available for buildings located
outside the SFHA. Information about the PRP and how one can apply is enclosed.
This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this
determination. If you have any questions about this document, please contact the FEMA Map Information eXchange (FMIX) toll free at (877)

ADDITIONAL INFORMATION REGARDING
LETTERS OF MAP AMENDMENT
When making determinations on requests for Letters of Map Amendment (LOMAs), the Department of
Homeland Security’s Federal Emergency Management Agency (FEMA) bases its determination on the
flood hazard information available at the time of the determination. Requesters should be aware that flood
conditions may change or new information may be generated that would supersede FEMA's determination.
In such cases, the community will be informed by letter.
Requesters also should be aware that removal of a property (parcel of land or structure) from the Special
Flood Hazard Area (SFHA) means FEMA has determined the property is not subject to inundation by the
flood having a 1-percent chance of being equaled or exceeded in any given year (base flood). This does not
mean the property is not subject to other flood hazards. The property could be inundated by a flood with a
magnitude greater than the base flood or by localized flooding not shown on the effective National Flood
Insurance Program (NFIP) map.
The effect of a LOMA is it removes the Federal requirement for the lender to require flood insurance
coverage for the property described. The LOMA is not a waiver of the condition that the property owner
maintain flood insurance coverage for the property. Only the lender can waive the flood insurance purchase
requirement because the lender imposed the requirement. The property owner must request and receive a
written waiver from the lender before canceling the policy. The lender may determine, on its own as a
business decision, that it wishes to continue the flood insurance requirement to protect its financial risk on
the loan.
The LOMA provides FEMA's comment on the mandatory flood insurance requirements of the NFIP as they
apply to a particular property. A LOMA is not a building permit, nor should it be construed as such. Any
development, new construction, or substantial improvement of a property impacted by a LOMA must
comply with all applicable State and local criteria and other Federal criteria.
If a lender releases a property owner from the flood insurance requirement, and the property owner decides
to cancel the policy and seek a refund, the NFIP will refund the premium paid for the current policy year,
provided that no claim is pending or has been paid on the policy during the current policy year. The
property owner must provide a written waiver of the insurance requirement from the lender to the property
insurance agent or company servicing his or her policy. The agent or company will then process the refund
request.
Even though structures are not located in an SFHA, as mentioned above, they could be flooded by a flooding
event with a greater magnitude than the base flood. In fact, more than 25 percent of all claims paid by the
NFIP are for policies for structures located outside the SFHA in Zones B, C, X (shaded), or X (unshaded).
More than one-fourth of all policies purchased under the NFIP protect structures located in these zones.
The risk to structures located outside SFHAs is just not as great as the risk to structures located in SFHAs.
Finally, approximately 90 percent of all federally declared disasters are caused by flooding, and homeowners
insurance does not provide financial protection from this flooding. Therefore, FEMA encourages the
widest possible coverage under the NFIP.
LOMAENC-1 (LOMA Removal)
The NFIP offers two types of flood insurance policies to property owners: the low-cost Preferred Risk
Policy (PRP) and the Standard Flood Insurance Policy (SFIP). The PRP is available for 1- to 4-family
residential structures located outside the SFHA with little or no loss history. The PRP is available for

427-4661. Before making a final decision about flood insurance coverage, FEMA strongly encourages
property owners to discuss their individual flood risk situations and insurance needs with an insurance agent

continuous coverage. Property owners may wish to note also that, if they live outside but on the fringe of the
SFHA shown on an effective NFIP map and the map is revised to expand the SFHA to include their
structure(s), their flood insurance policy rates will not increase as long as the coverage for the affected
structure(s) has been continuous. Property owners would continue to receive the lower insurance policy
rates.
LOMAs are based on minimum criteria established by the NFIP. State, county, and community officials,
based on knowledge of local conditions and in the interest of safety, may set higher standards for
construction in the SFHA. If a State, county, or community has adopted more restrictive and comprehensive
floodplain management criteria, these criteria take precedence over the minimum Federal criteria.
In accordance with regulations adopted by the community when it made application to join the NFIP, letters
issued to amend an NFIP map must be attached to the community's official record copy of the map. That
map is available for public inspection at the community's official map repository. Therefore, FEMA sends
copies of all such letters to the affected community's official map repository.
When a restudy is undertaken, or when a sufficient number of revisions or amendments occur on particular
map panels, FEMA initiates the printing and distribution process for the affected panels. FEMA notifies
community officials in writing when affected map panels are being physically revised and distributed. In
such cases, FEMA attempts to reflect the results of the LOMA on the new map panel. If the results of
particular LOMAs cannot be reflected on the new map panel because of scale limitations, FEMA notifies the
community in writing and revalidates the LOMAs in that letter. LOMAs revalidated in this way usually will
become effective 1 day after the effective date of the revised map.

1. INTRODUCTION
This Letter of Map Amendment (LOMA) has been prepared in order to certify that the existing
property within the Nakano project in the City of Chula Vista, California is above the flood
elevations as indicated on the NFIP map.
The purpose of the application is to demonstrate that the existing elevations of the Nakano property
are above the flood elevations indicated by Zone AE as shown in the FIRM Panel No.
06073C2158G, effective date May 16, 2012. The Zone AE floodplain extends along the north
portion of the site with water surface elevations ranging from 83.8 to 92.7 ft. MSL (NGVD 29).
Note that there a 2.17 conversion from NAVD88 to NGVD29 datum. The elevations listed on the
exhibit show elevations per the NGVD29 datum.
2. SUMMARY OF METHODOLOGY
The following summarizes how the base flood elevations were determined in order to ensure the
existing elevations are above the base flood and enable their removal from the special flood hazard
area mapping.
2.1 Existing Condition of the Property
The Nakano site consists of approximately 23.8 acres of existing hillside and grass land use located
within the Otay Mesa neighborhood of the City of Chula Vista. The site is bounded by Kaiser
Permanente medical offices to the South, Interstate 805 to the West, an existing residential site to
the east and Otay River to the North. Existing condition onsite includes grassland, hillside, utilities
facilities, and a small dirt paths traversing the property.
Per the FIRM panel, in the existing condition, the floodplain encroaches into the site along the
northern extents of the project boundary. Along the northern portion of the property the site is
affected by Zone AE. Refer to Exhibit A-1 for the existing floodplain exhibit depicting the
relationship of the floodplain to the property.

2.2 Floodplain Base Flood Elevation Comparison
The base flood elevations (BFE) were taken from the FEMA FIRM Panel No. 06073C2158G,
effective date May 16, 2012. The Zone AE floodplain extends along the north portion of the site
with water surface elevations ranging from 83.8 to 92.7 ft. MSL (NGVD 29). The lowest point on
the site along the northern property line is 95.7, three feet above the highest floodplain elevation
at the northwest corner of the site of 92.7. This comparison of the worst case scenario of the lowest
elevation on the existing property is still three feet higher than the highest floodway elevation at
any point on site indicates that the entire site can be removed from the special flood hazard area
mapping.
3. CONCLUSIONS
The existing property elevations indicate that the entire site is higher than the determined Zone AE
special flood hazard area base flood elevations for the Otay River. Therefore, this report supports
a recommendation that the entire property identified be removed from the 100-year floodplain
limits.

Public reporting burden for this data collection is estimated to average 1.63 hours per response. The burden estimate includes the time for reviewing instructions,
searching existing data sources, gathering and maintaining the needed data, and completing and submitting the form. This collection is required to obtain or retain
benefits. You are not required to respond to this collection of information unless a valid OMB control number is displayed on this form. Send comments regarding the
accuracy of the burden estimate and any suggestions for reducing this burden to: Information Collections Management, Department of Homeland Security, Federal
Emergency Management Agency, 1800 South Bell Street, Arlington, VA 20598-3005, Paperwork Reduction Project (1660-0015). NOTE: Do not send your completed
form to this address.
This form may be completed by the property owner, property owner’s agent, licensed land surveyor, or registered professional engineer to support a request for a
Letter of Map Amendment (LOMA), Conditional Letter of Map Amendment (CLOMA), Letter of Map Revision Based on Fill (LOMR-F), or Conditional Letter of Map
Revision Based on Fill (CLOMR-F) for existing or proposed, single or multiple lots/structures. In order to process your request, all information on this form must be
completed in its entirety, unless stated as optional. Incomplete submissions will result in processing delays. Please check the item below that describes your request:
LOMA A letter from DHS-FEMA stating that an existing structure or parcel of land that has not been elevated
by fill (natural grade) would not be inundated by the base flood.
CLOMA A letter from DHS-FEMA stating that a proposed structure that is not to be elevated by fill (natural
grade) would not be inundated by the base flood if built as proposed.
LOMR-F A letter from DHS-FEMA stating that an existing structure or parcel of land that has been elevated by
fill would not be inundated by the base flood.
CLOMR-F A letter from DHS-FEMA stating that a parcel of land or proposed structure that will be elevated by fill
would not be inundated by the base flood if fill is placed on the parcel as proposed or the structure is
built as proposed.
Fill is defined as material from any source (including the subject property) placed that raises the ground to or above the Base Flood Elevation (BFE). The common
construction practice of removing unsuitable existing material (topsoil) and backfilling with select structural material is not considered the placement of fill if the
practice does not alter the existing (natural grade) elevation, which is at or above the BFE. Fill that is placed before the date of the first National Flood Insurance
Program (NFIP) map showing the area in a Special Flood Hazard Area (SFHA) is considered natural grade.
Has fill been placed on your property to raise
ground that was previously below the BFE? Yes No If yes, when was fill placed? /
month/year
Will fill be placed on your property to raise
ground that is below the BFE? Yes* No If yes, when will fill be placed? /
