Regular City Council Meeting Monday,July 21, 2014 Page 19 soils for the most suitable use and area with clay soils serving best for foundations on which structures were placed; and compacted well for those building pads. Mr. Hanson assured Councilmembers that black soil would be used on top of any other soils to ensure proper growth and drainage to make these homes as aestheti- cally pleasing as possible for effective marketing and interest by potential buyers. While comments were made that the site seemed too low related to the wetland, Mr. Hanson advised that part of the dirt excavated would be located in the borrow pit and used to build up building pads to raise them, but in the interim, the soil had to be stored someplace, and thus the NE berm, not due to intentionally bring- ing in additional soils to the site; with the developer's intent to use up all the dirt possible for their various purposes. Mr. Hanson opined that, depending on how they compacted the soils back in, the NE berm could be smaller than indicated or even become non-existent; but assured Councilmembers that it would not create any drainage issues for the wetland or homes. Mr. Hanson further assured that all drainage issues would be addressed through the rain gardens and contained within the site itself. Mr. Hanson opined that the Owasso Boulevard berm would provide a great aes- thetic approaching the site. Councilmember Willmus expressed appreciation to Mr. Hanson for the explana- tion and understood the developer's rationale; but noted that his presentation indi- cated he would be bringing some materials on site for construction of slabs and radon mitigation; to which Mr. Hanson agreed. Mr. Hanson responded to Councilmember Willmus that residual soils would be used as applicable around the building pads and to achieve finished heights; and assured that the 908' elevation of the berm as shown on the grading plan would not be built to that height as plans became more final. At the request of Councilmember McGehee, Mr. Hanson further reviewed their intent to address clay soils and mitigate surface drainage; and defined good and bad soils from the perspective of a builder/developer and their particular uses on a construction site. Mr. Hanson reiterated that a critical aspect of the building pro- cess was to ensure for all proper heights and properly sloped water drainage. In response to concerns expressed by Councilmember Etten as to the 908' height of the berm, which he found extreme, Mr. Hanson advised that their intent was to put as much soil into the site as feasible and as a builder he was not going to ac- cept a high berm; but as a developer he wanted to ensure beautiful yards and beautiful homes; not to create an aesthetic reflecting a"burial mound." Specific to gradients of the site adjacent to wetlands and water control during and after construction as expressed by Councilmember Etten, Mr. Hanson advised that all water movement calculations now existing were related to current movement;
