Owl's Nest Residence French Drain Installation
NOE - Notice of Exemption
Install French drain at the Owl's Nest state residence at Point Lobos Ranch to prevent continuous pumping of the outdated septic system and to prevent flooding of the house. Work will excavate 270 lineal feet to trench up to 3' deep and 12' wide to install 160 lineal feet of French drain and 110 of drainage pipe to carry water from the drain to a natural drainage course. Installation of the 160 linear foot French drain includes laying a geotextile liner, 160 linear feet of perforated plastic 4" diameter pipe, and placing drain rock within the trench. Work will connect the perforated pipe to 110 lineal feet of solid plastic pipe that will be bedded with sand on all sides. The top of the trench will be covered with excavated material and any excess will be spread evenly in an approximately 4" layer over existing septic to create smoothly graded surface.
Project consists of construction and location of limited numbers of new, small structures; minor alterations in the condition of land, water, and/or vegetation that do not involve the removal of healthy, mature, scenic trees.
