<br />(CITY OF LOUISVILLE BENCH MARK NO. 49) ELEVATION =5324.64,
<br />2. THE LOCATION OF THE UNDERGROUND UTILITIES SHOWN HEREON ARE BASED ON THE
<br />FIELD LOCATION OF SURFACE FEATURES, AND AS -BUILT LOCATIONS FROM MAPS
<br />PROVIDED BY THE APPROPRIATE UTILITY COMPANIES AND THE CITY OF LOUISVILLE.
<br />THE AUGNMENT, DEPTH AND SIZE OF THE SAID UTILITIES SHOWN HEREON MAY NOT BE
<br />ACCURATE, SCOTT, COX & ASSOCIATES, INC. RECOMMENDS THAT THE LOCATION OF THE
<br />UNDERGROUND UTILITIES BE FIELD VERIFIED PRIOR TO ANY DIGGING ON, OR
<br />ADJACENT TO THE SUBJECT PROPERTY.
<br />3. GRADE AWAY FROM THE BUILDING A MINIMUM OF A 6 INCH DROP IN THE FIRST 10
<br />FEET IN LANDSCAPE AREAS.
<br />4, THE FEMA FLOOD INSURANCE RATE MAP, PANEL 08013C0578 F. DATED JUNE 2. 1995,
