t~ver MEMORANDUM TO: Jeremy Barnhart, Planning Manager FROM: Rebecca Haug, Environmental Administrator DATE: February 4, 2009 SUBJECT: Y 09-01 -Fred McCoy -McCoy's Pub V - 09-0 I -Fred McCoy -This application does not meet the Shoreland Ordinance. The Environmental Division does not support. this application due to the amount of impact to the bluff. The bluff setback of 30' has been set due to the instability of the bluff. Bluffs are inherently much steeper and sensitive to impact than a hill or steep slope. Also, with any river, there is a chance for meandering and thus making this bluff even more susceptible to impact. It appears after inspections of the site that this area is on an outside curve of the river which creates more chance for meandering. Hence, the bluff setback protects the river by reducing the chance for erosion and bank sloughing. This application also does not meet the impervious surface coverage standard in Section 30-2025. Stormwater management (2) Specific Standards a. The ordinance states that impervious surface coverage of lots shall not exceed 25 percent of the lot area. The existing structure plus the addition would cover approximately 70 percent of the lot. The purpose for this section is to reduce the amount of runoff from a site prior to discharging in to the storm sewer system or directly into the river. Water runoff from impervious surface typically contains pollutants and is heated which causes water quality issues. Part of the City's NPDES Permit is to require more infiltration and reduce the amount of impervious surface throughout the City. If you have any questions, please let me know. Thank you for the opportunity to review the applications.
