(L) 
Submit a letter from a responsible person for a source of water supply, certifying as to the availability of water and its ability to serve the subdivision, or submit a letter from the Environmental Health Services of the County Health Department, certifying as to the ability of the subdivision to meet requirements of Part IV of the Design Criteria Manual.
(M) 
Submit a letter from a responsible person for a source of sanitary facility, such as a sanitation district, certifying as to the availability, capacity, and its ability to serve the subdivision, or, submit a letter from the Environmental Health Services of the County Health Department certifying as to the ability of the subdivision to provide individual sewage disposal systems.
(N) 
Public areas proposed, if any.
(O) 
In areas to be developed, contours shall be drawn to intervals as follows:
Slope
Interval
0.00%—1.00%
1 foot
1.00%—10.00%
2 feet
10.00% and over
10 feet
Contours shall be accurate to within one-half a contour interval. In areas not to be developed, greater intervals may be permitted which shall be extended into adjacent property a sufficient distance to establish proper topographical relationships.
(P) 
Statement of the improvements proposed to be made or installed.
(Q) 
Typical cross sections of all streets.
(R) 
Date, north point and scale.
(S)

(U) 
Show the approximate known soil or geologic hazard areas.
(V) 
Submit four copies of the preliminary soils report noted in SCCC § 14.01.432 or two copies of the waiver noted in SCCC § 14.01.433.
