For Mercer Island's wet, mild climate, angular crushed rock (for example 3/4u0022 crushed rock) is generally best for driveways because it compacts and sheds water well. For walking paths and decorative areas, pea gravel or river rock look attractive but move more and drain differently; consider crushed rock with a top layer of pea gravel for appearance without sacrificing stability.

Permit requirements vary by project scope, slope, and whether work affects public right-of-way or storm drains; small resurfacing jobs often do not require a permit, but removals, significant regrading, or work in the right-of-way may. Contact the City of Mercer Island Public Works or King County permitting to confirm rules for your specific address before starting work.

King County and Mercer Island focus on reducing runoff and protecting Puget Sound, so gravel can be helpful if it increases infiltration and prevents concentrated runoff. However, design matters: use proper base layers, avoid directing sediment into drains, and consider permeable sections, infiltration swales, or vegetation to meet local stormwater expectations; check local codes for larger projects.

On slopes, use a compacted crushed-stone subbase, geotextile fabric to separate soil from stone, and solid edging (wood, metal, or concrete) to prevent lateral migration. For steeper driveways add a base of angular crushed rock and consider terracing or low retaining walls; always have the driver place material where you want it and compact in layers for best stability.

Expect routine maintenance like raking and filling low spots after heavy rains, with a light top-up usually needed every 1 to 3 years and more substantial topping or regrading every 3 to 6 years depending on use and slope. Regular maintenance after the rainy season and addressing rutting quickly will prolong the surface and reduce long-term costs.

Pea gravel is attractive and comfortable underfoot but tends to move and requires edging and more frequent topping, making it less durable for driveways. Crushed rock compacts well, provides a stable surface for vehicles, and usually gives better long-term value; pea gravel may cost slightly more per cubic yard installed because of extra prep and containment needs.

Mercer Island has a mild freeze-thaw regime, so frost heave is less of a concern than in colder inland areas, but heavy rain can wash fines and create ruts. Proper installation with good drainage, adequate base, and periodic topping will keep gravel surfaces functional for many years despite frequent rain.
