NOTE
1. ALL EXPOSED EDGES SHALL BE ROUNDED TO A 15 mm (HALF INCH) RADIUS.
2. THE CURB FACE AT POINTS A AND D SHALL BE THE NORMAL CURB FACE OF THE ADJACENT CURB.
THE CURB FACE AT POINTS B AND C SHALL BE THE NORMAL CURB FACE OF THE ADJACENT CURB
PLUS H (SEE APPLICABLE CATCH BASIN STANDARD PLAN).
3. IN EXISTING STREETS WHERE NO PAVEMENT REMODELING IS INDICATED, THE ELEVATION OF THE
OUTER EDGE OF THE LOCAL DtOkESSMON SHALL MEET "THE tINIS.HED STREET SURFACE.
4. IN NEW STREETS, OR IN EXISTING STREETS WHERE PAVEMENT REMODELING IS INDICATED:
THE _ELEVATIONS OF POINTS F AND G SHALL BE SET H1 HIGHER THAN THE GUTTER FLOW LINE
ELEVATIONS AT POINTS A AND D, RESPECTIVELY
THE ELEVATIONS OF POINTS P AND R SHALL BE SET Hz HIGHER THAN THE GUTTER FLOW LINE
ELEVATIONS AT POINTS B AND C, RESPECTIVELY'.-.
THE ELEVATION OF POINT S SHALL BE SET H2 HIGHER THAN THE ELEVATION AT THE NEAREST
GUTTER FLOW LINE.
WHERE THERE IS NO GUTTER ADJACENT TO THE LOCAL DEPRESSION, THE ELEVATION OF gNr
E SHALL BE SET H9 HIGHER, THAN THE ELEVAT16N AT THE NEAREST TOE OF CURB.
