M A S T E R P L A N F O R L W D P APPENDIX A KOTTINGER CREEK EXISTING CONDITIONS Lions Wayside Park contains a stretch of Kottinger Creek (described in this document as a drainage swale) that enters the park from a culvert at First Street, runs westerly into the park, and turns southwest to run parallel to the old SPRR right of way, and into a culvert under Neal Street. In Lions Wayside Park, its dimensions vary, but the drainage swale is generally approximately 6-8 feet deep and averaging approximately 30 feet wide, from top-of-bank to top-of-bank. For most of its length within the park its banks are steep-angled dirt.The flowline is mostly dirt, with some rocks, gravel, and concrete rubble scattered along the bed. Close to Neal Street, flat-faced granite boulders intermittently line its banks, mostly on the west side. In Lions Wayside Park, there is little to no vegetation below the tops of its banks. Trees on and adjacent to its banks appear to be (at least mostly) non-native. At one time, this stretch of drainage way may have been the route for a significant seasonal flow. However, some time prior to 1990, retention basins were installed (in the Kottinger Ranch housing development), and the City made a set of significant storm drain improvements. Currently, this stretch of the creek is dry most of the year, and only small quantities of water are found, no more than four months of the year, and mostly in times of heavy precipitation events. Within Delucchi Park, the creek enters the park from a culvert at Neal Street (the connection to Lions Wayside Park), and runs parallel to the old SPRR right of way, and into a culvert under West Angela Street. It is approximately 6-8 feet deep, averaging approximately 20 feet wide, with almost vertical sides, and is lined with stone and rip/rap. The bottom and sides are vegetated with both native and non-native plants. This stretch appears to contain water year-round. In its current condition, the creek within the two parks has a mixed esthetic and hydrologic character. Not only is it different on each side of Neal Street, but on both sides of the street it is neither natural nor completely engineered. Within Lions Wayside Park, it is mostly bare dirt, steep-sided, unmeandering, and mostly dry. Within Delucchi Park it is green, rock-lined, straight in course, and wet (year-round). APPENDIX A A- I
