Hand excavated french drains are recognized by city and county
The past summer I had the pleasure of hand excavating french drains for the Columbia County Fairgrounds in St. Helens, Oregon. The fair grounds had extensive downspout and groundwater runoff that caused a bad erosion problem because no french drains were installed previously along their major ingress-egress street and in front of the large access doors on three of the largest exposition barns. After the completion of the french drains, and many oversized hand excavated drywells, the fairgrounds management was extremely happy. No more sloppy areas in front of the barn doors and along the roads.
French drains can be used in agricultural and farm settings as well, as in this example, to create dry and safe areas for the containment of livestock and exposition areas as well as around farm houses and storage areas.
If you have a farm property, you may want to look into the installation of hand excavated french drains to protect your expensive livestock dry feed storage areas, and to keep your barns from flooding with the winter rains.
