6.b) Staff Report-Scandia Parks and Trails Native Plant ProgramSCANDILA Staff Report Date of Meeting: February 4, 2013 To: Parks and Recreation Committee From: Kristina Handt, City Administrator Re: Scandia Parks and Trails Native Plant Program Agenda Item #: 6.b) Background: Tom Vogen had requested this item be placed on the agenda at the January meeting. Committee member Arnold also has an interest in further discussing this issue. Included in your packet is a copy of Screening and Landscaping Section from Chapter 2 of the Development Code. While this does not apply to parks (applies to single family and multi- family development and commercial/industrial development) it may help the committee formulate guidelines for parks as well. Issue: Does the committee want to adopt additional guidelines that establish a program requesting/requiring native plants in City park and recreational areas? If so, what are the guidelines? Proposal Details: None specific at this time. Further committee discussion is needed to formulate ideas. The committee should discuss if the guidelines will be mandatory or voluntary? In formulating ideas the committee may also want to consider aesthetics, maintenance and cost when comparing native and non-native plantings. Fiscal Impact: Depends on how the committee would like to apply the guidelines. Will all plantings in park and rec areas be required to be replaced with native species and if so will the City pay for that or will the guidelines be implemented as funds are donated from non -city sources? Options: The committee should discuss and come to some agreement regarding the items discussed above. This will provide staff with the information necessary to begin drafting a Scandia Parks and Recreation Native Plant Program Guidelines document that can then be further reviewed at the next meeting. If the Committee wants to adopt guidelines for the City to use when evaluating proposals, the guidelines would need to be recommended to the City Council and ultimately approved by them.
