Open Space Advisory Board Minutes March 9th 2015 Page 4 of 6 City Council scheduled a study session with OSAB and other advisory boards for April 12th. They sent each board a list of discussion questions to answer to help foster conversation. Helen went through the Council's communication with the board. Helen said that she would use the board's previously - generated lists to answer questions #1 and #2 and opened discussion for the rest of the questions. Christopher commented that term limits are "good government," as they bring new ideas and give more people have the chance to serve. He suggested six years as an optimal maximum. The board observed that there don't seem to be very many people who are not reappointed by Council when their appointments are up for review, meaning that currently people generally serve as long as they wish. Most of the board felt like term limits might be a good idea, but thought that it took a few years to get optimally productive, so any term limit should be long enough to let people gain the relevant expertise. The board suggested two questions to put to City Council. The first was to ask if the City is moving towards a more proactive and systematic Open Space Land acquisition process. The board would like to attach Missy's acquisition memo to this document, so Council can see it again. The second question was to ask if Council would oppose OSAB working with the new Parks board (PPLAB) on dog issues, as they seem to be an important, complex, and recurring City issue. The document needs to be submitted to Council by April 5, so Helen will fill out the document by the end of next week and send it to board members for review over email. X. Discussion Item: OSAB Recommendation for Davidson Mesa Parking Lot Surfacing Alternatives Staff had prepared a spreadsheet showing costs of different surfacing alternatives for remediation of the dust problem at the Davidson Mesa Parking Lot. Mr. Steve Rasor began the discussion by showing a recent video he took from his property adjacent to Davidson Mesa. It showed of a steady stream of dust being blown off the Davidson Mesa Dog Off -Leash Area. It was the board's observation that the dust didn't come off crusher fine trails, or normally- vegetated areas, just in the denuded, worn - down, de- vegetated areas of the Dog Off -Leash Area. Mr. Rasor remarked that whether or not there is remediation done on the parking lot, the Dog Off -Leash Area will still produce lots of dust, and that dust is potentially contaminated by dog waste. The board discussed the irony of dogs not being allowed at Harper Lake due to water contamination fears, when contaminated dust from the Dog Off -Leash Area constantly blows into it. Helen got clarification that the $25,000 quoted for the "soil stabilizer" option includes an initial professionally -done surface "regrade," but then the product itself would be about $500 -1000 per year for subsequent applications. Ember said that the manufacturer suggested a twice - yearly application. Linda asked what was done wrong when the parking lot was built that makes it function improperly. Ember answered that the initial problem was that a concrete ring around the center of the lot (the vegetated island) that blocked the central drainage. Staff recently added cuts in the ring and 4 french drains. Upon reviewing the options listed in the packet, Graeme commented that the "high" current annual maintenance costs that were mentioned during the previous meeting were only about $500 /year, which doesn't seem so onerous compared to the cost of the remediation options. Mike and Laura both suggested that the soil stabilizer option, combined with a system of better, more aggressive closures during adverse conditions, should be tried before paving the lot, for reasons both aesthetic and economical. Missy wanted to go further and make a statement that the OSAB opposes 5
