Bird Nest Box Specifications <br />A total of five (5) bird nest boxes are proposed to attract a variety of passerine birds to the <br />buffer area. The nest boxes will be placed on live trees, five (5) to 20 feet above the ground. <br />The exact locations of the nest boxes will be determined by a qualified biologist on site. <br />Prefabricated nest boxes are widely available for a variety of birds. The specific nest boxes <br />to be installed shall be selected in consultation with a consulting biologist. <br />Nest Box Notes <br />■ Boxes should be made of solid wood, preferably cedar, and should be watertight. <br />■ Perches shall not be placed below the entrance hole. Perches attract nuisance <br />species such as starlings. <br />■ The nest boxes should have hinged roofs for annual cleaning. Boxes should be cleaned <br />out once a year after the young have fledged. <br />■ Ventilation holes should be placed near the top and holes should be placed in the floor <br />for drainage. The roof should overhang the ventilation holes and the entrance <br />sufficiently to preclude rain from entering the box. <br />Is Most birds prefer boxes mounted on trees five (5) to-20 feet above the ground. Nest <br />boxes should be placed at least 50 feet apart to account for the territorial nature of <br />most bird species. <br />■ Boxes should be placed where they will receive at least some shade during the day. <br />■ Nest boxes are available from many commercial and retail suppliers. The estimated <br />cost for a nest box and installation is $50.00/each. <br />TEMPORARY EROSION AND SEDIMENT CONTROL (TESC) <br />Silt fencing shall be placed along the edge of the proposed buffer impact area during <br />construction to protect the adjacent wetlands from siltation. It shall be installed per <br />Department of Ecology standards, heeled -in at the bottom along its length and supported <br />with wire fencing and steel fence posts. Proper installation of the TESC fencing will insure <br />that impacts to downstream areas from sedimentation are minimized to the greatest extent <br />possible. All sedimentation control facilities shall be kept in place and functioning until <br />vegetation is firmly established. The TESC plan developed by the site engineer shall govern <br />all TESC measures. <br />CRITICAL AREA SIGNS AND FENCING <br />Signage and fencing shall be placed to permanently mark the boundary of the buffers (see <br />Critical Area Study Map). A permanent fence shall be constructed along the buffer <br />boundaries, as shown on the attached map. Critical area signage shall be attached to the <br />fence posts, as shown. Exact sign design, language and locations shall be approved by the <br />City of Everett. An example of critical area sign text is as follows: <br />Critical Area Study and Buffer Mitigation Plan 12 WRl# 09084 <br />lntermec- Lot 2 Revision#2: March 22, 2010 <br />
