2 <br />Error! Unknown document property name. <br />included in the open space area. Road rights-of-way and buildable lots <br />are not considered open space area. <br />Cluster development means a pattern of subdivision development which places dwelling units into <br />compact groupings while providing a network of commonly owned or dedicated open space. Lots <br />within a cluster development typically do not meet minimum lot width and area requirements. <br /> <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 reduce <br />setbacks since the lot area requirements are reduced. Rural Residential <br />requires a 10-acre minimum lot size. Adding new language to the sections is <br />intended to offer clarity. <br />B. Update Open Space PUD Design Standards - 105.12.1050 <br />Development Types: The department proposes two development types in an OP <br />PUD. For applying development standards, projects within an Open Space PUD <br />shall be considered either a traditional or a cluster development. By default, a <br />project shall be considered a traditional development. If 10 percent of the single- <br />family lots within the proposed project do not meet the standards for a traditional <br />development, the project shall be determined to be a cluster development. <br /> <br />1. Density. <br />• Staff are suggesting increasing the density from .45 units per acre to .8 <br />units per acre. The reason for increasing density is two-fold. First, the <br />existing density is based on 1 acre lots and many of the developments <br />are less than 1 acre with a communal drain field. Secondly, increasing <br />density should make development in Lake Elmo more economically <br />competitive. <br />2. Density bonus. <br />• Staff are also proposing a 10% density bonus for sites with considerable <br />wetlands or natural area or stormwater reuse for irrigation. Currently <br />there is a 20% density bonus for similar sites outlined in the standard <br />PUD section. For clarity, this bonus is outlined in the OP-PUD section <br />of code. The reduction in percentage from 20% to 10% is based on the <br />newly proposed increase to the base density. <br />3. Septic design identification. <br />• Based on feedback from the city engineer, staff have added low pressure <br />sewer guidance to sites proposing communal drain field. <br />4. Identification of required buffers. <br />Staff are proposing amending the language in this section for conciseness <br />and clarity. <br />5. Placement of streets. <br />• Based on feedback from the city engineer, staff added clarifying <br />language to permit 28-foot-wide streets with parking on one side of the <br />road. This language is meant to add flexibility for developers while <br />maintaining high design standards and connectivity for the city.
