Douglas McAteer, Assistant City Engineer °~ SUBJECT: Storm Drain in Easement from Hill Street to Raymond Avenue Easterly of 5th Street. A sump area in Raymond Avenue, easterly of 5th Street produced, is drained by means of a 15-inch storm drain (lying in a 10-foot easement) onto Hill Street. This 15-inch drain is to be connected to a proposed Los Angeles County Flood Control Project (578 - Line J) sometime during 1964. During a storm of any magnitude the sump area in Raymond Avenue is in a flooded condition, due to the fact that the 15-inch storm drain is unable to carry the runoff required of it. It is proposed in our Master Plan of Storm Drains to increase this storm drain to a 24-inch size. During this year a new apartment house has been built on Lot 7. Building plans have also been approved for construction of an apartment building on Lot 8. If this building is constructed prior to replacing the storm drain, it grill be extremely expensive to construct the drain because of: (1) the narrow working area, (2} possi- bility of footings ..being undermined, (3 replacement of walks, steps, etc.., and (4) the fact that there also is a sanitary sewer in this easement. It is recommended that the City Council be requested to appropriate,~;5,000 in order that this office may issue a purchase order to have this storm drain re- placed (between Raymond Place North and Hill Street) as soon as_possible. The remaining portion of the drain (Raymond Avenue to Raymond Place North) will be constructed at some future date. Attached is a portion of Drawing No. 5007 indicating the portion of the drain to be constructed at this time.
