Speed signs have been shown to slow down drivers.  For several years, the BHA has been working to have several installed at trouble spots around Brentwood.  Yesterday, Councilman Rosendahl and community leaders dedicated one on Sunset near the sight where Julia Siegler was killed in a tragic accident.  The City fronted the money, but will be reimbursed by private funds from families and for the one on north Bundy, Mount St. Mary’s College.
