converted to anon-agricultural use. <br />(3) A lawn within the riparian buffer ceases to be <br />maintained. <br />B. Zones within the Riparian Buffer <br />The protected riparian buffer shall have two zones as follows: <br />1. Zone l shall consist of a vegetated area that is undisturbed except for <br />uses provided for in the Table of Uses, Section 4. The location of Zone 1 <br />shall be as follows: <br />a) Far intermittent and perennial streams, Zone 1 shall begin at <br />the most landward limit of the top of the bank or rooted herbaceous <br />vegetation, and extend outward a minimum distance of 30 feet on <br />all sides of the surface water, measured horizontally on a line <br />perpendicular to the surface water. <br />b) For ponds, lakes, and reservoirs located within a natural <br />drainage way, Zone 1 shall begin at the most landward limit of the <br />normal water level or the rooted herbaceous vegetation and extend <br />landward a minimum distance of 30 feet, measured horizontally on <br />aline perpendicular to the surface water. <br />c) Zone 2 shall consist of a stable, vegetated area that is <br />undisturbed except for activities and uses provided for in the Table <br />of Uses, Section 4. Grading and revegetation is allowed provided <br />that the health of the vegetation in Zone 1 is not compromise. Zone <br />2 shall begin at the outer edge of Zone 1 and extend landward a <br />minimum of 20 feet as measured lorizontally on a line <br />perpendicular to the surface water. The minimum combined width <br />of Zone 1 and Zone 2 shall be 50 feet on all sides of the surface <br />water. <br />C. Diffuse Flow Requirement <br />Diffuse flaw of runoff shall be maintained in the riparian buffer by dispersing <br />concentrated flow and reestablishing vegetation. <br />1. Concentrated runoff from new ditches or constructed conveyances <br />shall be converted to diffuse flow before the runoff enters the riparian <br />buffer. <br />2. Periodic corrective action to restore diffuse flow shall be taken if <br />necessary to impede the formation of erosion gullies. <br />Section 4 Table of Uses <br />The following chart sets out the uses and their designation under this Ordinance as <br />exempt, allowable, allawable with mitigation, or prohibited. The requirements for each <br />category are given in Section 4.A. <br />
