|   Here’s another popular jaunt for 
          local residents.  Nature lovers and dog-walkers frequent the area, 
          parking on the rim of the Arroyo or in the parking lot of Pasadena’s 
          Lower Arroyo Nature Park.  They then walk down to the horse stables at 
          the South Pasadena city limits or up to the Colorado Street Bridge 
          where you can cross the flood channel.  The northern part of this area 
          contains the BFI low-flow stream experiment.  Controlled flows are 
          diverted below the Colorado Street Bridge and directed into 
          streamzones on both sides of the flood channel.  The riparian habitat 
          has become so thick that it is often hard to see the stream.  The flow 
          in the artificial streams sometimesis turned off because of sediment 
          buildup and maintenance problems. Still the area is a welcome oasis 
          from the urban hustle-and-bustle.
 
 Arroyo Seco Park is 19.9 acres of improved parkland, 
        including lighted athletic fields, playground equipment, and picnic 
        areas. There are also included undeveloped lands, and a flood channel.
          
         The park is divided into three sections: The upper 
        section includes three lighted sports fields with backstops, parking and 
        a small concession/storage building, and it is utilized regularly by the 
        local Little League, American Youth Soccer Organization and softball 
        leagues.   A residential building is located on the north side 
        of the park.   The center portion of the park includes: group picnic 
        shelter, tables, barbecue, a playground with play structures, storage 
        building and a small amphitheater.   The southern portion of the park includes two lighted 
        softball fields.   Both the upper and lower parts of the park are 
        utilized for soccer during the fall season.   An equestrian/hiking trail is on the south and west 
        perimeter of the park connecting to the Arroyo Park.   Arroyo Park: The 19.9 acre Arroyo Park is located on 
        the north sided of the Pasadena 110 Freeway. Aroyo Park provides major
