There is <br /> varying void space depending on the substructure, but for all District purposes we treat it with the same <br /> cover as green space. There is a different calculation when it comes to the runoff(curve) numbers <br /> however. If you have any further questions, please let me know. <br /> Steve Christopher <br /> Regulatory Program Manager <br /> 18202 Minnetonka Blvd. <br /> Deephaven, MN 55391 <br /> 952.471.0590 x207 <br /> Fax: 952-471-0682 <br /> www.minnehahacreek orq <br /> _ . <br /> t�i <br /> MINNEHAHA CREEK <br /> WATERSHE� OISiRICT <br /> From: John Roedel [mailto:John@CNCTool.com] <br /> Sent: Friday, July 16, 2010 1:27 PM <br /> To: Steve Christopher <br /> Cc: Luke Schwitzer <br /> Subject: City of Orono Variance Application <br /> My variance hearing is this Monday July 19, 2010. <br /> I request a statement regarding how MCWD would view the installation of a pervious paver patio at 4725 <br /> North Shore Dr. Orono MN 55364. <br /> I purchased this home not knowing the previous builder built the house larger than was permitted. He <br /> used up "hard cover". <br /> When I bought the house I viewed three patio doors downstairs that exited to the back yard. <br /> I, obviously, made the conclusion that I would have a patio. <br /> The city of Orono is resisting my variance request. <br /> The area where I would like the pation is 4" -8" of clay loam. <br /> The city of Orono wants sod over this clay loam. <br /> I would replace this clay loam with sand, however deep the city would like me to go, so that the <br /> permiability of the soil would be increased. <br /> With the new sand rather than clay loam,l believe a pervious paver patio over the sand would allow better <br /> environmental results than grass over clay. <br /> If you could assist me with a statement before late Monday afternoon it would be greatly appreciated. <br /> I have gotten all eight neighbors around me to sign "adjacent property owner's acknowledgement forms" <br /> approving the patio. <br /> Please give me any advise or call with any questions. <br /> This is VERY important to me. <br /> Thank you in advance, John Roedel <br /> �`".���.,. <br /> � � 7/19/2010 <br />
