the roundabout. This allows the option for bicyclists to ride up onto the sidewalk area and then walk their bikes across the crosswalks. The crosswalks are protected by raised islands, where applicable, so that pedestrians only have to deal with traffic on one side of the road at a time. Bicyclists may also choose to ride through the roundabout along with other vehicles. In this case, the size of the roundabouts slows cars to cycling speeds. The round- about design also follows the federal roundabout design guidelines that specifically warn against striping any bike lane within a roundabout: striping a bike lane within a roundabout tends to increase bicycle collisions. A 5 Comment: Commissioner Roberts asked how children would get across Pleasanton Avenue. Response: plans for an expanded, signalized intersection of Pleasanton Avenue/Bernal Avenue are provided in Figure 5 of the Bernal Community Park (BCP) Master Plan. The intersection modifications will include painted crosswalks and pedestrian signal indicators that include a countdown of how much time is remaining to cross the street. (Note that the BCP graphic is the correct representation of the proposed layout of this intersection; Specific Plan Figure 5-5 and DEI R Figure 20 are not accurate and are to be corrected.) A 6a Comment: Kevin Close observed that the hydromodification section of the DEI R indicated an increased water flow into the onsite channels. Response: The designed storm drainage facilities throughout the Bernal property routes storm water runoff two different ways. For new impervious surfaces (streets, driveways, roofs, parking lots, etc.) storm water runoff is directed to storm drain piping systems that direct flow through the two large detention basins constructed on the western parcel and central parcel. Although these detention facilities were constructed during Phase I development of the site, they were sized to accommodate full future development of the property. Areas that remain open land, similar to the natural condition of the property, are allowed to flow directly to the storm drainage channels across the property, bypassing the detention ponds. A 6b Comment: Kevin Close reported that at the Council meeting on the Specific Plan, an interest was shown in permeable pavers for the parking lots as opposed to crushed granite; he expressed concern for problems of groundwater contamination resulting from parking lot treatment. Response: The comment indicates that there has been some interest shown in using a per- meable paving solution for the project parking lots and expresses some concern regarding the potential for groundwater contamination associated with the infiltra- tion of pollutants through the permeable pavers. It should be noted that the DEI R did not specifically recommend the use of permeable pavers in the parking lot. How- 6
