Ditch flows slowly to the north Photo 1. Wetland DE: Looking west across Wetland DE from upslope. Ponded water, mucky mineral soils, and patches of emergent vegetation observed. Wetland DE appears to be supported from groundwater and surface runoff from the street to the west (N 113 th Place) (January 2, 2015). ESA PhotoPage 1
Wetland drains south Photo 2. Wetland K: Looking south into Wetland K. Wetland K flows south into Thornton Creek wetland complex. Wetland boundary is located at the toe of the roadway embankment slope and follows the toe of slope of a sewer easement that is approximately six to eight feet higher than the wetland elevation (January 13, 2015).

Ditch drains north Photo 4. Jurisdictional Ditch A: Jurisdictional Ditch A is located along the road shoulder to I-5. Looking south into the drainage. Leaf litter and debris observed in Jurisdictional Ditch A (January 13, 2015). ESA PhotoPage 4
Ditch drains south Photo 5. Jurisdictional Ditch A: Jurisdictional Ditch A is located along the road shoulder to I-5. View of south end of Jurisdictional Ditch A looking north. Culvert drains south into the stormwater system. Leaf litter and debris observed in the drainage (January 13, 2015). ESA PhotoPage 5
Ditch drains to the south Photo 6. Jurisdictional Ditch B: Looking northwest at culvert inlet into Jurisdictional Ditch B. Note sidecasts from ditch maintenance to the right of the six inch drainage flow path (January 2, 2015). ESA PhotoPage 6
Culvert drains under I-5 Ditch drains north Photo 7. Jurisdictional Ditch C: Jurisdictional Ditch C is located on the west edge of the WSDOT right-of-way, west of the noise wall. Looking north along Jurisdictional Ditch (January 13, 2015). ESA PhotoPage 7
Photo 8. Jurisdictional Ditch C: Looking south at Jurisdictional Ditch. Wetland DE is located beyond the orange flag and flows north into Jurisdictional Ditch C. Stormwater pipes also empty into Jurisdictional Ditch C (January 13, 2015). ESA PhotoPage 8
Photo 9. Jurisdictional Ditch C: Culvert at north end of Jurisdictional Ditch C drains east under I-5. Remnant chunks of cement and asphalt observed at north edge of Jurisdictional Ditch C just before the culvert (January 2, 2015). ESA PhotoPage 9
Ditch drains to the south Photo 10. Jurisdictional Ditch H: Looking north along Jurisdictional Ditch H. Roadside ditch along I-5 off-ramp. Jurisdictional Ditch H receives runoff from surrounding roads and drains to the south into a stormwater drain. (January 2, 2015). ESA PhotoPage 10
Northern extent of stormwater feature located at the south end of Jurisdictional Ditch L. The feature is fed by the ditch upslope Photo 11. Jurisdictional Ditch L: Looking north at Jurisdictional Ditch L from top of sewer easement embankment. At the south end of Jurisdictional Ditch L is a constructed stormwater feature. Culvert at south end of Jurisdictional Ditch L drains into Wetland K. (January 2, 2015). ESA PhotoPage 11
Ditch drains south to stormwater feature at the south end of Jurisdictional Ditch L Photo 12. Jurisdictional Ditch L: Looking south along Jurisdictional Ditch L from upslope (January 2, 2015). ESA PhotoPage 12
Feature F on road prism of I-5 onramp Photo 13. Feature F. Looking north at eastern side of unregulated Feature F along the road prism to I-5 (January 2, 2015). ESA PhotoPage 13
Photo 14. Feature F. Unregulated Feature F is located along the road prism to I-5. View looking west along the slope (January 2, 2015). ESA PhotoPage 14
Culvert Drains to the south Photo 15. Stormwater Feature G. Looking north along Stormwater Feature G. Roadside swale along I-5 off-ramp. Stormwater Feature G receives stormwater flow from culvert at north end (January 2, 2015). ESA PhotoPage 15
Drains south Stormwater Drain Photo 16. Stormwater Feature J. Looking southeast at the southern extent of Stormwater Feature J, a roadside swale along the on-ramp to I-5. Stormwater Feature J receives runoff from the road, and drains to the south into a stormwater drain (January 2, 2015). ESA PhotoPage 16
Stormwater Feature M Beginning of scour lines marks boundary between Stormwater Feature M and Jurisdictional Ditch L Jurisdictional Ditch L flows east, then south Photo 17. Stormwater Feature M. Looking northwest into unregulated Stormwater Feature M, a roadside swale along the on-ramp to I-5. Unregulated Stormwater Feature M receives runoff from the road, and drains to the southeast into Jurisdictional Ditch L (January 2, 2015). ESA PhotoPage 17
