(4) Yield plan. If the project includes a conservation subdivision or planned unit development, <br />the applicant shall submit a yield plan showing the maximum number of dwelling units that <br />would be permitted given the minimum lot size and lot widths for conventional subdivisions <br />and other requirements of the Lino Lakes Zoning and Subdivision Chapters. <br /> <br />A conservation development is the same as a conservation subdivision. <br /> <br />The applicant submitted a yield plan utilizing a similar street layout and 80ft wide lots. The plan <br />generated 69 single family lots and a net density of 1.52 units per acre. This does not meet the <br />required low density residential range of 1.6 to 3.0 units per acre. Additional lots would be <br />required resulting in potentially greater wetland impacts. <br /> <br />Another yield plan could have been submitted showing the maximum number of R-2 twins <br />homes (approximately 135 units) that would be permitted using traditional zoning <br />requirements. <br /> <br />Attached is another example of a Traditional Development vs Conservation Development of the <br />original 2006 Natures Refuge Concept Plan. The Traditional Development has 300 lots that <br />extend into the wetlands, stormwater ponds, woodland areas, and open space and provides <br />limited protection or public access to these amenities. The Conservation Development has 278 <br />smaller lots that creates more protected accessible public open space and establishes the <br />greenway corridor. The trail system in the conservation development is also incorporated into <br />the greenway system vs. along the street creating a more enjoyable, safer, and valued <br />recreational experience. <br /> <br />The purpose of using the PUD zoning is to create a conservation development that establishes <br />the defined public values of preserving and enhancing the on-site natural resources. The PUD <br />also creates and enhances the greenway corridor and trails that are accessible to the public. <br /> <br />Environmental Review Record <br /> <br />As previously noted, in 2006 a mandatory Environmental Assessment Worksheet (EAW) was <br />prepared for the original Natures Refuge concept because the proposed 278 housing units <br />exceeded the 250 housing unit threshold. The EAW thoroughly analyzed potential impacts to <br />wetlands, rare plant and animal species, floodplain, water quality, noise, traffic and archeology. <br />It was determined the project did not have the potential for significant environmental effects <br />and the Council passed Resolution No. 07-06 making a Negative Declaration on the Need for an <br />EIS. <br /> <br />The scope and size of the existing Natures Refuge and proposed Natures Refuge North (168 <br />housing units on 155 gross acres) is smaller than the original 2006 proposal (278 housing units <br />37
