Required Canopy Cover = (Impervious Surface Area/Total Lot Size) x Pervious <br />Surplice Area <br /> <br />(392,040sq. fl/871,200sq, ft.) x 479,160 sq. ft. = 215,622 sq. ft. of required <br />canopy cover. <br /> <br />To determine the square footage of canopy cover for an individual tree, the minimum and <br />maximum spread of a species will need to be determined (these are listed in the Ramsey <br />Tree Book). Also, the species needs to be identified as either an acceptable or preferred <br />species in the Ramsey Tree Book. <br /> <br />For example: <br /> <br />Swamp White Oak (Preferred Species): {[(25 + 50)/2]/2}2 x r~ x 0.80 = 884 <br />square feet <br /> <br />Black Ash (Acceptable Species): {[(25 + 45)/2]/2}2 x r~ x 0.65 = 625 square feet <br /> <br />In addition to the R-2 and R-3 Residential Districts, Staff has also noticed that the multi- <br />family landscape requirements were erroneously repeated in the R-1 Residential District. <br />This text needs to be eliminated as the R-1 landscaping requirements are simply 2 trees <br />per lot.. A copy of the edited version of the R-1 landscape requirements is also enclosed <br />for your information and review. <br /> <br />Recommendation: <br /> <br />City Staff recommends approval of the proposed landscaping amendments. <br /> <br />Commission Action: <br /> <br />Motion to recommend that City Council adopt an ordinance to amend the landscape <br />requirements in the R-1, R-2 and R-3 Residential districts. <br /> <br />Copies To: <br /> <br />Asst.
