Gutter, Drainage & Grading Audit
on the Eastside, every lot has an opinion about where water should go - usually downhill, toward the lake, sometimes through your foundation.

Seasonal Maintenance
What this article helps you decide
> This is the Eastside checklist. Nearly every lot in town drains toward Lake Washington, so grading, downspouts, and retaining walls decide whether winter water runs past your foundation or into it. Trace the water before the rain does.
Work through the decision in order
Roof to ground
Clear gutters; check for overflow stains. Trace every downspout to a working discharge point well downslope - not against the foundation.
The grade (the Eastside part)
Confirm the ground falls away from the foundation, especially on the uphill side. Note pooling and soggy ground after the first heavy rain.
Slope hardware
Check retaining walls for bulging, cracks, and blocked weep holes. Look for uphill/neighbor water crossing the lot; check area drains and swales.

Questions about Gutter, Drainage & Grading Audit
Clear answers first. If one question changes the deal, bring it into the review before you move money.
Q1Why is grading the single most important maintenance item on these lots?+
Because nearly every lot slopes toward the lake, so grading, downspouts, and retaining walls decide whether winter water runs past your foundation or into it. Get the water routing right and most downhill problems never start.
Q2Where should my downspouts actually discharge?+
Well downslope, to a working discharge point away from the foundation — never dumping against the house. Overflow stains and pooling at the base are the tell that a downspout is feeding the foundation.
Q3What am I checking on a retaining wall, and when is it serious?+
Bulging, cracks, and blocked weep holes. Weep holes that can't drain build water pressure behind the wall; bulging or leaning means it's already losing. On a slope, the uphill wall protects everything below it, so price it first.
Q4How do I spot a grading problem I can actually see?+
After the first heavy rain, look for pooling, soggy ground, and water flowing toward the foundation rather than away, especially on the uphill side. Rain is the cheapest diagnostic you'll get.
Q5How much should drainage weigh in an offer on a slope lot?+
A lot. Grading and retaining walls quietly move offers because the fixes range from regrading to five-figure wall work. Read the lot before you write, not after inspection.
Q6I found uphill or neighbor water crossing my lot — what now?+
That's a shared-water issue: area drains, swales, or an interception drain usually handle it, but the fix depends on volume and property lines. Map it before the wet season and get a drainage contractor's read.
