SUBJECT: Base Flood Analysis fora "Tuff Shed", 20845 Cheney Drive, Topanga,California, 90290.

REF.: Structural Plan Set of the "Tuff Shed", 2085 Cheney Drive,Topanga, California, 90290, prepared by GeoWorks EngineeringGroup, Inc., Dated September 24, 2014.

Base Flood Elevation Analysis and Interpolation Calculation,prepared by GeoWorks Engineering Group, Inc.

Gentlemen:

As requested I have performed a site observation and walk through of the above reference

existing "Tuff Shed". In addition I have reviewed the referenced Structural Plan Set,

FEMA Flood Map, and Los Angeles County GIS map.

BASE FLOOD ELEVATION ANALYSIS

The Base Flood Elevation Parameters: The Base Flood Elevation parameters were

obtained from the referenced FEMA Flood Map. The Subject Site is located between

two mapped base flood elevations located in the Santa Maxia Canyon. The upstream base

flood elevation is delineated as 973 feet and the downstream base flood elevation is

delineated as 932 feet. The FEMA Flood Map was assigned a scale of one inch equals

one unit.

BASE FLOOD ELEVATION CALCULATION

A Base Flood Elevation calculation was performed utilizing an Interpolation Equation to

determine the approximate Base Flood Elevation between the documented upstream base

flood elevation and the downstream base flood elevation. The approximate base floodelevation at the subject site was calculated to be 937 feet as shown on the referencedcalculation.

BASE FLOOD ELEVATION MAPPING

Utilizing the referenced GIS map and the calculated base flood elevation at the subjectsite the approximate limits of the base flood being an elevation of 937 feet was mappedalong with the Finish Floor of the "Tuff Shed" being an elevation of 952 feet.

SUMMARY

The above itemized Base Flood calculations and mapping indicate that the Tuff Shed isapproximately 15 feet above the base flood elevation. This is well over the required onefoot requirement.

Based on the above discussion, calculations, and mapping, it is the opinion of this officethat development of the "Tuff Shed" on the subject property as shown on the referencedStructural Plan Set is well above one foot above the base flood elevation and would not
