City Council Meeting Minutes August21, 2018 Page 7 of 13 Councilmember Loo stated there were discussions about working with the HOA to make certain no drainage water from the residences was being funneled to the open space. Has that been done? Director Kowar stated that information was conveyed to residents to ask them to reroute downspouts to the front of their Tots away from the open space. He stated some residents did try to do it but there is no way to measure the effect. Councilmember Loo asked if the revegetation costs are included. Director Kowar stated yes. Councilmember Loo would like an estimate of that cost. Director Kowar stated that will be a line item in the contract. Councilmember Maloney noted this is a serious issue and we are responsible to fix it. He noted Terracon stated there is no immediate risk of failure. Do we need to push this so quickly given there is no imminent peril? Do we need a sole source contract if there is no immediate peril? This design/build does not give us options to consider. Director Kowar stated soils engineering is a specialty and Hayward Baker is one of few companies that can do this work. Given the busy construction market we don't know if an RFP would getus a better price or product, but it would take a lot more time. We might be able to work through a layered process of dewatering and pinning slope back first, but in the end these will likely be a part of any design. Mayor Muckle stated this seems to be a case where we would want to use the same people who design it to build it so they have to stand behind both. He stated he is not interested in a multistep process that takes longer to get the open space restored. We should do it all at once with a reputable company who will stand by the process. If we need more time we should take it with Hayward Baker. Councilmember Stolzmann stated she supports the contract. It should be noted one monitor changed by 10 feet during the monitoring. We should be proactive to get homeowners in the area to keep groundwater off the site while we are working on this. There was a localized increase in water during irrigation season and we should be direct about that. Shestated her only concern with the proposal is all the pinning is on the south side; she wonders why nothing is needed on the southeast side of the failure. Mayor Muckle moved to approve an initial staff controlled budget of up to $75K for a contract with Hayward Baker for the design phase of a design/build services contract for the Coyote Run mitigation with additional services from Terracon; Councilmember Keany seconded. Mayor Muckle asked for discussion on the motion. Councilmember Maloney asked which funds will be used to pay for this project. City Manager Balser stated Council decided on July 12 to split the costs of this 50/50 between the Capital Projects Fund and the Open Space & Parks Fund.
