The casca ading drainagge system shown in the LAM article for the pools s serve to slo ow and store e stormwater without thee need for neew drainagee systems noor irrigation. Exotics do o not slow or r store storm mwater and, tthey requiree massive ammounts of irrigation.

Last Fall, I took an ea arly retireme ent incentiv ve as Vice PPresident withh the Hudsoon River Park Trust in Manhattan M (N NYC). Prev viously, I was a professoor for twentyy years at at number of universiti ies, mostly the Univers sity of Califor rnia (UC). Thhe project toook place in the late 19880s and early y 1990s while I was wit th UC. I apologize that I don't have immediate aaccess to prooject information but can provide p prov vide more de etails, imagess, updates, etc if the prooject is seleccted. This project has prov vided 25 yea ars of outstanding stormwwater management; aessthetics for tthe Interstate e 80; habitat t for endange ered species s; and, counntless hours of educationn, research and public se ervice opport tunities for K-12, K univers sity, adult annd communitty members. . The Vernaal Pools of the Interstat te 80 and Highway 113 interchange look and peerform beauutifully thesee days!
