AR5ROVED AS TO -FORM: _J - z�vao� City Attornef PUBLISHED: CITY or PASCO POST OFFICE BOX 293 1 TELEPHONE (509) 547-8801 1 PASCO, WASHINGTON 99301 April 22, 1969 Mr. Horace E. Menasco, City Manager Pasco City Hall r Pasco, Washington Re: Swimming Pool Code Dear Mr. Menasco: The City of Pasco does not presently have a code regulating construc- tion or maintenance of private swimming pools. Public and semi-public (motel) pools are regulated by State Law under the State Health Depart- ment. There is a need for such a code to be adopted by the City due - to the increased number of pools being built. It is anticipated that the construction of swimming pools will continue to increase and to alleviate future problems concerning construction standards, they should be controlled by ordinance. This ordinance should be concerned with the safety and sanitation of the owners and their guests, and can only be accomplished through controlled construction. The Uniform Swimming Pool Code covers all aspects of -pool construction and maintenance and would provide the City with needed guide lines. Added to the code, as written,.is a section on fencing and a section on zoning regulations. These were added to controLsafe operation and proper location on the property.. Sin erely,` Lyle E.

McGarry Secretary POST OFFICE BOX 293 1 TELEPHONE (509) 547-8801 [ PASCO, WASHINGTON 99301 April 22, 1969 Mr. Horace E. Menasco, City Manager Pasco City Hall Pasco, Washington Re: Swimming Pool Code Dear Mr. Menasco: The City of Pasco does not presently have a code regulating construc- tion or maintenance of private swimming pools. Public and semi-public (motel) pools are regulated by State Law under the State Health Depart- ment. There is a need for such a code to be adopted by the City due to the increased number of pools being built. It is anticipated that the construction of swimming pools will continue to increase and to alleviate future problems concerning construction standards, they should be controlled by ordinance. This ordinance should be concerned with the safety and sanitation of the owners and their guests, and can only be accomplished through controlled construction. The Uniform Swimming Pool Code covers all aspects of pool construction andmaintenance and would provide the City with needed guide lines. Added to the code, as written, is a section on fencing and a section on zoning regulations. These were added to control safe operation and proper location on the property. VSinerely, Lyle E.
