What the disclosure stack holds
Most of Lafayette outside the downtown flats is mapped High or Very High fire hazard. Menlo Park FEMA zones trigger flood insurance at $800-$2,500 a year. None of this substitutes for the parcel: check CAL FIRE zoning, the FEMA flood panel and CGS seismic hazard mapping, then price the policy in writing.
Choosing between them
Lafayette works for a buyer who wants a third-acre lot within a 10-minute drive of rail. Menlo Park is the answer when the commute has to be under fifteen minutes. The decision is which requirement is load-bearing, because neither submarket satisfies both lists.
