'j Pinyon it is recommended that the developer follow MBTA nest survey guidelines as outlined by CPW during the nesting season (CPW, 2008) (see included Attachment). • If construction activities occur in mapped wetland and riparian areas, Pinyon recommends that formal wetland delineations are conducted as described in the USACE Wetland Delineation Manual and a Section 404 permit is obtained before any ground disturbance occurs (Environmental Laboratory, 1987). The informal wetland delineation described in this memo is not a formal wetland delineation. As such, the data and results presented within this memo are for planning and avoidance purposes only and are not suitable for use in permitting documents. • Land owners are required to have a plan to manage noxious weeds and, because of the noxious weed species and the number of noxious weed species present in the study area, Pinyon recommends that an integrated noxious weed management plan is generated for this site. The plan would help with managing weeds before and during project activities. Limitations This memo was prepared by Pinyon, at the request of and for the sole benefit of Civil Resources, LLC., or any entity controlling, controlled by, or under common control with Civil Resources, LLC. The conclusions and recommendations offered in this report are based on the data obtained from a limited number of samples, within a prescribed study area as described in the text. Soil, hydrologic, vegetation, biological and ecological conditions typically vary even over short distances, by season, by elevation, and by meteorological conditions. Thus, the nature and extent of variations outside this biological investigation may not become evident except through further investigation. It is possible that ecological conditions may change from those observed, particularly over time. This memo is the exclusive and present use of Civil Resources, LLC., or any entity controlling, controlled by, or under common control with Martin Marietta. Ecological analysis has been performed for specific conditions during the course of this investigation, as described in the text. This study makes no attempt to assess ecological/biological conditions not searched for as described in the text. Conclusions stated herein refer only to the specific site at the time of the investigation. Attachments: Figure I. Site Location Figure 2.
