HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR <br />CITY OF SANTA ANA <br />5. Environmental Analysis <br />CULTURAL RESOURCES <br />American Heritage Commission (NAHC). These sections also require notification of discoveries of <br />Native American human remains to descendants and provide for treatment and disposition of human <br />remains and associated grave goods. <br />• California Public Resources Code 5097.98 states that in the event of discovery or recognition of any <br />human remains in any location other than a dedicated cemetery, "there shall be no further <br />excavation... until the coroner... has determined... that the remains are not subject to ... provisions of law <br />concerning investigation of the circumstances, manner and cause of any death, and the <br />recommendations concerning the treatment and disposition of the human remains have been made to <br />the person responsible.... The coroner shall make his or her determination within two working days from <br />the time the person responsible for the excavation, or his or her authorized representative, notifies the <br />coroner of the discovery or recognition of the human remains. If the coroner determines that the <br />remains are not subject to his or her authority and ... has reason to believe that they are those of a Native <br />American, he or she shall contact, by telephone within 24 hours, NAHC." <br />California Senate Bi1118 <br />Senate Bill (SB) 18, the Traditional Tribal Cultural Places (TTCPs) law, requires local jurisdictions to provide <br />opportunities for involvement of NAHC and any appropriate California Native Americans tribes in the land <br />planning process for the purpose of preserving TTCPs. A city or county, when proposing to adopt, amend, <br />revise, or update a general plan or specific plan, must send a written request to NAHC asking for a list of <br />tribes to consult. NAHC is required to provide this list within 30 days of receiving the request. The city or <br />county must send a Tribal Consultation Request letter to each tribal representative on the list; tribes then have <br />90 days in which to respond to the Consultation Request if they want to consult with the local government to <br />determine whether the project would have an adverse impact on the TTCP. <br />SB 18 provides a new definition of TTCP requiring a traditional association of the site with Native American <br />traditional beliefs, cultural practices, or ceremonies or the site must be shown to actually have been used for <br />activities related to traditional beliefs, cultural practices, or ceremonies. Previously, the site was defined to <br />require only an association with traditional beliefs, practices, lifeways, and ceremonial activities. In addition, <br />SB 18 also amended California Civil Code Section 815.3 and adds California Native American tribes to the list <br />of entities that can acquire and hold conservation easements for the purpose of protecting their cultural <br />places. <br />Natural Setting <br />The project area is underlain by young alluvial fm sediments consisting of unconsolidated to moderately <br />consolidated silt, sand, pebbly cobbly sand, and bouldery alluvial fm deposits and are of Holocene and late <br />Pleistocene age (USGS 2006). The Holocene Epoch extends from the present to approximately 11,500 years <br />before present (ybp); the Pleistocene Epoch extends from about 11,500 ybp to approximately 1.8 million ybp. <br />Elevations in the project area range from approximately 92 feet above mean sea level (amsl) along the <br />northeastern portion of the area to approximately 62 feet amsl along the southwest portion of the area; the <br />project area has a southwest slope of approximately 0.3 percent grade. <br />Page 5.3 -2 PlaceWorkr <br />
