Ramona Hog Lake Road Improvement Project August 2011<br />

The Project area has no Federal or State listed noxious weeds, but has low levels of<br />

invasive weed species. The weeds are concentrated along <strong>road</strong> shoulder. The<br />

primary concern is to keep <strong>the</strong> current populations of weedy species from spreading<br />

both within and beyond <strong>the</strong> Project area.<br />

The dominant vegetation type occurring in <strong>the</strong> Project area is red shank chaparral,<br />

which becomes susceptible to weed invasions after disturbance. The effects of<br />

disturbance associated with <strong>road</strong>s and drainage structure construction will be<br />

reduced by implementing mitigation measures/design criteria (see Table 1:<br />

Mitigation Measures/Design Criteria; Weed Risk).<br />

Determination<br />

The weed risk <strong>for</strong> pathways of introduction is Low based on <strong>the</strong> minimal impacts in<br />

construction and <strong>the</strong> Design Criteria <strong>for</strong> <strong>the</strong> Project which will limit <strong>the</strong> movement of<br />

invasive plants.<br />

Heritage Resources<br />

A series of policies, laws and regulations govern <strong>the</strong> preservation of our past in <strong>the</strong><br />

United States. The most important of <strong>the</strong>se is <strong>the</strong> National Historic Preservation Act<br />

(NHPA). This law and its implementing regulations, 36 CFR Part 800, recognize that<br />

historic properties significant to <strong>the</strong> Nation’s heritage are being lost and that <strong>the</strong><br />

cultural foundations of <strong>the</strong> Nation should be preserved as a living part of our<br />

community life and development in order to give a sense of orientation to <strong>the</strong><br />

American people (16 U.S.C. 470 (1)(b)(2-3)). In 1980 <strong>the</strong> NHPA was amended, and<br />

Section 110 was added to expand and underscore Federal agency responsibility <strong>for</strong><br />

identifying and protecting historic properties and avoiding unnecessary damage to<br />

<strong>the</strong>m. This Act specifies a set of criteria to be used <strong>for</strong> designating historic properties<br />

(e.g., districts, sites, buildings, structures, and objects etc.) as significant. Significant<br />

properties are eligible to <strong>the</strong> National Register of Historic Places (NRHP). Section<br />

106 of <strong>the</strong> NHPA compels federal agencies to take into account <strong>the</strong> effect of its<br />

undertakings on any district, site, building, structure or object that is included in or<br />

eligible <strong>for</strong> inclusion in <strong>the</strong> National Register of Historic Places (36 CFR 60) (Historic<br />

Properties).<br />
