owners. Mr. Culver further reported that the roadway is located within railroad right-of- <br /> way, with the easement for that roadway essentially for the purpose of granting property <br /> access. Mr. Culver noted that the situation was further complicated by the fact that the <br /> roadway and its maintenance is not within the purviews of a homeowner's association of <br /> those property owners. Therefore, Mr. Culver reported that, to-date, the road had been <br /> handled as a minimum maintenance roadway; with the city plowing it only to provide <br /> access to a fire hydrant and other facilities at the end of the private road. <br /> Member Heimerl asked if staff had any idea of the contaminants flowing into the lake <br /> form this area; and whether the project was needed. <br /> Mr. Culver responded that the runoff from the roadway did discharge directly into the <br /> lake from this gravel road, including some actual sediment from the road. Mr. Culver <br /> advised that he was not aware that there was a particular concern with phosphorus from <br /> that runoff, but noted the project would address rate control in addition to that sediment. <br /> Member Heimerl asked staff about the life-expectancy of these pavers long-term with <br /> plowing and other maintenance and uses. <br /> Mr. Freihammer reiterated that, with the blocks tied together in large sections versus laid <br /> side by side, they wouldn't move as much but flex as a unit. While he anticipated that <br /> long-term, some edges may get more rounded, Mr. Freihammer noted that if and when <br /> necessary the cable connecting them could be cut and blocks relocated or replaces. <br /> Member Heimerl expressed his appreciation for the proactive nature of the proposed <br /> project, as long as all short- and long-term issues were understood. <br /> Member Wozniak asked about the long-term maintenance with this type of design and <br /> keeping the pavers permeable. <br /> Mr. Freihammer advised that they would require sweeping by vacuum to keep the pores <br /> open. However, Mr. Freihammer noted there would not be any additional flow from off- <br /> site areas; and therefore, should prove more than adequate as long as the paver blocks are <br /> swept to avoid plugging those pores. <br /> As an additional component of this project, Chair Stenlund asked if residents had <br /> expressed any interest in rain gardens or other pre-treatment form their property edge; or <br /> would they be given a maintenance plan (e.g. don't rake leaves or lawn clippings onto the <br /> pavers, or don't change oil on the pavers). Member Stenlund noted the need to educate <br /> the homeowners to make sure the system remained functional. <br /> Mr. Freihammer advised that staff would need to provide some education on the layout of <br /> the road. However, Mr. Freihammer noted that the topography of this area was different, <br /> in that the residential properties drain away from the road onto their properties before <br /> reaching the lake. Mr. Freihammer assured commissioners that there would definitely be <br /> Page 4 of 7 <br />
