The ordinance codified in this chapter has three (3) attachments, each on file in the city clerk-treasurer's office. The first is an inventory map with known public drinking water sources and wellhead protection zones delineated thereupon. The second is an inventory of the known public water sources within the city, showing well number, location, depth, GPM and notes. The third is a table, entitled "Columbia River Basalts". This table is used to calculate the fixed radius of the wellhead protection zones. (Ord. 136 § 9, 1994)
