Page 41, Policy 3 of the Ramsey Plan should be Policy 3.4, See previous comments regarding wetland protection standards, Item 2.

Page 43, Policy 6.5 of the Ramsey Plan states; The use of grassed waterways shall be encouraged to' maximize infiltration. Proper grades shall be maintained or underdrain systems installed as part of an overall site plan to insure positive drainage, • The use of an underdrain system does not provide for infiltration but rather filtration of storm water.
