l catch basins and discharges through a pipe within retention area that has been built on the south- side f Route 2 . Route 130 in Barnstable, loo-king towards Stratford Ponds, shows four catch ba-sins, one of which allows water to overflow. There is- a small amount of sediment around the bas-in.; a small amount that travels towards the Santuit River. The only recourse Mashp e has would be to begin to collect the runoff beyond Stratford Ponds from the highpoint and intercept and direct it back -i .to the ground. antuit River at old mill Road on the Ma hpee side appears- to be in good condition. This area probably has the most impact for the Santu.it River on both sides of the road. There are paved waterways on .both sides very close to the river. The river is a narrow channel with wetlands on both skies before going into the higher vegetated area . There are some natural filtering mechanisms in the form of the wetland area that- border the river on both sides.. There is a subdivision on the Barnstable side that contributes a portion of t 'e runoff towards the San uit River. There is a pipe culvert on the north side of old Mill Road. The sediment in this area washes directly towards the river. The south side of the river shows an old stone culvert. uInac uisset Avenue at the Mashpee River Woodland's at Route 28 shows catch basins, guardrails, and behind the wooded area a large detention area where m st of the runoff accumulates . The catch basin grates are high capacity, capable of taking a lot of water. There is no evidence of erosion in this area. Quinaquisset Avenue east from the Route 2 intersection shows the location of pared waterways that dump off to the south side of the road, an area h re there is some damage at the bank and walkway. The roadway is pitched; the runoff goes directly toward the paved waterways . 6
