96 <br /> sometimes does result in projects that may not necessarily focus or factor on an addressing an affordability concern. <br /> Ultimately this property will not yield sufficient density to make development of what some might construe an <br /> affordable housing project viable but this project does focus more on the preservation and protection of the <br /> environmental components related to the property. <br /> David Blankfard: In the packet on-pages 40 and 41,you have a memo from Mr. Fleming, the stormwater supervisor. <br /> Can you explain what his conclusions were? <br /> Michael Harvey: I can try. I'll remind you about what I told you last month when the concept plan was reviewed. This <br /> project will have to go through a stormwater permitting process. The process will have to demonstrate that proposed <br /> stormwater facilities will not only comply with our code, but also address nutrient reduction requirements. I think that <br /> what Mr. Fleming is attempting to identify is that he would like to see the SCM, stormwater control measure,to <br /> accommodate more of the potential development on the housing side not just the roadways and overall land <br /> disturbance activity for the project. Mr. Smith has indicated this evening that they are going to be looking at each <br /> individual lot in terms of some disconnected stormwater flow feature to address on lot development activities,so you <br /> don't have to over design the stormwater feature which actually incorporates some of the low impact design <br /> elements. This is an attempt to try to address some of the duality of the ordinance with respect to how do we comply <br /> with the stormwater standard, and at the same time, how do we achieve reasonable development of property. <br /> David Blankfard:What I'm understanding is you are going to take care of some of the runoff on the individual pieces <br /> of property. <br /> Tim Smith: The ones we can,yes. <br /> David Blankfard: If you can't take care of it on the property you're going to pipe it over to the SCM. <br /> Tim Smith: Since this letter,we've done more in regard to what his concerns were, and we're headed in the direction <br /> that we need to be for the overall project. We're increasing the size of our primary device areas,so they have more <br /> capacity and we're also incorporating a tiered approach to stormwater to obtain the treatment required for the entire <br /> property. <br /> Michael Harvey: Just to reiterate, Mr. Smith has gone through a rather detailed recitation of the various techniques <br /> they're looking at. As part of your recommendation, you can ask the Board to consider that if they choose to adopt <br /> this project,that those suggestions be incorporated in the resolution of approval and that these are the steps that the <br /> applicant will take in terms of addressing and incorporation of low impact design elements. This project cannot be a <br /> process of low impact design development because it exceeds thresholds. I think it's perfectly reasonable for this <br /> Board to recommend to the County's Commissioners to consider making that a requirement as part of the resolution <br /> of approval if it gets approved. <br /> Kim Piracci: Even if they build in three,four, different ways to control flooding, it's still only stormwater <br /> measurements of one inch of rainfall in 24 hours. They don't have to accommodate three inches of rainfall. <br /> Michael Harvey: No, that's the minimum base standard as currently contained within the UDO. <br /> Hunter Spitzer: Is that standard set by the state or can we change that? <br /> Michael Harvey: The State establishes minimum guidelines and requirements. If we choose to be more restrictive we <br /> can do that, but the State would have to give us the authorization to do that. If this Board is interested, it could <br /> request the County Commissioners to study whether or not there's an opportunity to implement a higher stormwater <br /> management standard that should be adopted recognizing that there are impacts. Of course with more restrictive <br /> standards comes higher development costs,which can translate to more expensive homes. <br /> David Blankfard:Tim, if you did treat it more than one inch,what would that impact be on your SCMs? <br />
