2 <br />Open space area means the measurement of all undeveloped land and <br />natural features within a subdivision or planned unit development. <br />Trails outside of the road rights-of-way and agricultural buildings are <br />included in the open space area. Road rights-of- way and buildable lots <br />are not considered open space area. <br />2. 105.12.1120 (Zoning Code – Planned Unit Development Regulations) Add <br />clarification to the intent of Planned Unit Developments. See attached for proposed <br />update. <br />3. 105.12.980-105.12.1110 (OPEN SPACE PLANNED UNIT DEVELOPMENTS) <br />A. Add clarity to setbacks for accessory use - (105.12.1040) <br />• Staff identified confusing language around setbacks within the OP-PUD for <br />accessory structures. The added language and accompanying table are based <br />on underlying zoning districts. Adding new language to the sections is <br />intended to offer clarity. <br />B. Update Open Space PUD Design Standards - 105.12.1050 <br />1. Density. <br />• Staff is suggesting increasing the density from .45 units per acre to .8 <br />units per acre. The reason for increasing density is two-fold. First, it is <br />intended to preserve more open space and natural resources, which is in <br />line with the primary goals of OP-PUD. Secondly, increasing density <br />makes development in Lake Elmo more economically competitive. <br />2. Septic design identification. <br />• Based on feedback from the city engineer, staff has added low pressure <br />sewer guidance to sites proposing individual septic tanks. <br />3. Identification of required buffers. <br />Staff is proposing amending the language in this section for conciseness and <br />clarity. <br />4. Placement of streets. <br />• Based on feedback from the public works director and city engineer, <br />staff added permissions for 28-foot-wide streets with parking on one <br />side of the road. This language is meant to add flexibility for developers <br />while maintaining high design standards and connectivity for the city. <br />5. Lot creation. <br />• Staff is suggesting that single-family lots that are served by individual <br />septic tanks utilizing communal drain fields decrease in size from <br />21,780 square feet to 16,000 square feet. Staff also propose a 100’ <br />minimum lot width and a 160’ minimum lot depth. These changes are <br />meant to encourage development and have been reviewed by the city <br />engineer as acceptable. <br />6. Lot specific buildable areas. <br />• Added setbacks for accessory structures. <br />7. Open space and park land adjustments. <br />• The development is required to construct a stormwater reuse pond for <br />irrigation. <br /> <br />C. Update Open Space PUD Development Standards – 105.12.1060 <br />1. Building standards. <br />• Staff is proposing adding an attached garage standard to be more <br />consistent with the city’s design standards. Staff is proposing that the
