Sammamish, WA PLUS

Water in crawlspace. Upon checking it, water is coming in from high spot in lot. A crawlspace specialist came out and told resident that water is not coming from patio, downspout or gutters it is coming form street. Perhaps s/w line is broken which is spilling into lot/crawlspace.

The culvert north of driveway, along the guard rail, ist over grown with blackberries and debris, it would be time to have get a good cleaning again.

Stormwater from my neighbor's asphalt area/driveway in front of his garage pours over the property line into my backyard. This asphalt area clearly slopes to my property. There is a drainage catch near the edge of the asphalt but it is not adequate to divert all the stormwater from the asphalt.

I ran across this while cleaning up the area. This grate was (is) overgrown and against a bank which is allowing dirt to enter it. Water from the street was no longer entering this drain and is just running down the street. Just wondering if this is something you are interested in reviewing or cleaning etc.

The gutter line for the sidewalk is damaged and causes the sidewalk to sink. There is a lot of rain water coming from the hill above.

Caller is concerned about drainage pipe and runoff on their property. Stormwater drains to and fills the ravine to the west of their house. It is causing concern for increased potential of a landslide. Would like someone to visit to discuss. Would prefer a phone call to coordinate a site visit.

City's Capital Improvement Project (CIP) for Louis Thomson Road SURVEY-ing dug in roadside ditch, placed "marker(s)" and left a pile of loose sandy, erosive soil. With just initial rains, this activity has ignored the existing and necessary roadside ditch and sandy-erosive soils in/near Landslide Hazard area. Already there are at least two quite large HOLES need fixing--with property soils/fill/compaction, and ensure the DITCH can and will work as FALL/WINTER rains have started and are coming.

I'd like to report a safety concern. Yesterday, I saw nailed wood planks on trees, littering (chairs, construction lumbers, foams, pulley...etc) on parcel 290930TR-B, connecting to Vintage 5 in Sammamish.
