The <br />compacting of the bank material was considered to be more effec- <br />tive than rip-rapping since the rip-rapping was tried before. <br />The water flow eroded the loose material around the rip-rapping <br />rendering it ineffective. <br />Approximately 250 feet of the ditch downstream of the culvert was <br />deepened as advised. <br />I trust that this repair meets with your approval. <br />Sincerely, <br />E.
