Slow Spread Sink (Sonoma Valley)

Best land management practices for storm water runoff.

The idea is to slow water runoff down - permeable surfaces work better and this can be applied not only to the ground but also roofs (that have impermeable surfaces).  Spread it around via rain barrels, french drains and other methods such as vegetated slopes and various gardens.  You don't want water to immediately be directed to pipes and culverts off your property.  Finally: let it sink!  Water can erode if there is not enough greenscaping - bare ground can be an issue just like pavement.  Use gravity, include swales and rain gardens and provide some xeriscaping on higher grounds.

This guide by Sonoma Valley on beneficial stormwater management is very comprehensive and provides lots of tips to homeowners and landowners.
