A Qualified Storm Water Pollution Prevention Plan Practitioner will oversee implementation of the Plan, including visual inspections, sampling and analysis, and ensuring overall compliance.
Project contractors will implement an erosion and sediment control plan, which includes storm water best management practices (BMPs) required by the City’s storm water permit and other applicable regulations. This erosion and sediment control may be substituted by a Storm Water Pollution Prevention Plan prepared in accordance with Order No. 2009-0009, as long as the Plan includes measures equivalent to those listed below:
• Erosion Control: Schedule the Project to sequence construction activities with the installation of erosion and sediment control measures and preserving existing vegetation. Utilize a combination of BMPs to minimize soil erosion, including hydraulic mulch, hydroseeding, soil binders, straw mulch, geotextiles and mats, and wood mulching (CASQA Handbook BMP EC-1 to EC-8 or Caltrans Handbook BMP SS-1 to SS-8).
• Sediment Controls: Install a combination of BMPs to detain sediment-laden runoff, including fiber rolls, gravel bag berms, street sweeping and/or vacuuming, storm drain inlet protection, sediment basins; check dams, silt fencing, and sand bag barriers (CASQA Handbook BMP SE-1, SE-2, SE-4, SE-5, SE-6, SE-7, SE-8, SE-10) or Caltrans Handbook BMP SC-1, SC-2, SC-4, SC-5, SC-6, SC-7, SC-8, SC-10).
• Tracking Controls: Install a stabilized construction entrance/exit and entrance/exit tire wash at the site to minimize the tracking of sediment onto public roads (CASQA Handbook BMP TR-1 and TC-3 or Caltrans Handbook BMP TC-1 and TC-3).
• Additional Controls: Implement wind erosion controls and stabilized construction roadways as needed (CASQA Handbook BMP WE-1 and TC-2 or Caltrans Handbook BMP WE-1 and TC-2).
• Non-Storm Water Management: Implement a combination of BMBs to prevent the potential for non-storm water discharges, including water conservation practices, dewatering operations, and vehicle and equipment washing/fueling/maintenance (CASQA or Caltrans Handbook BMP NS-1, NS-2, NS-8, NS-9, NS-10).
• Waste Management: Implement general site and materials management BMPs, including material delivery and storage, stockpile management, spill prevention and control, solid waste management, concrete waste management, and sanitary/septic waste management (CASQA and Caltrans Handbook WM-1, WM-3, WM-4, WM-5, WM-8, and WM-9).

The Project applicant will obtain coverage in the Sonoma County Medical Facility Scene Call Program (MEDF Program). The MEDF Program includes a protocol for designated medical facilities meeting certain criteria to receive an ambulance- only response to a 911 call. The Santa Rosa Fire Department has deemed the Project’s inclusion into the MEDF Program as being necessary for the proposed use of the site. Inclusion into the MEDF Program allows approved Skilled Nursing Facilities, Clinics, and other facilities with medical staff to defer a fire department first response if warranted by patient condition. Certain patient conditions or specific facility requests will continue to receive a standard fire/emergency services response. In order to participate in the program, the Project applicant will submit a MEDF Program application form, which would be reviewed by local fire and emergency responder agencies, Coastal Valleys Emergency Medical Services Agency and Redwood Empire Dispatch Communications Authority, before being approved. In addition, the Project applicant will require that lift team training be provided to all employees working on-site as part of their first-week employment orientation.

MM BIO-1b: Avoid Impacts to Nesting Birds
The City of Santa Rosa shall ensure the following measures to avoid impacts to nesting birds are followed:
• To the extent possible, grading or removal of any vegetation shall be conducted outside the nesting season, which occurs between approximately February 1 and August 31. No preconstruction nesting bird survey is required for work conducted outside this period.
• If limiting grading or vegetation removal between August 31 and February 1 is infeasible and work must occur within the nesting season, a pre- construction nesting bird (both passerine and raptor) survey of the landscaped areas and trees shall be performed by a qualified biologist within 7 days of ground breaking. If no nesting birds are observed, no further action is required and work shall occur within one week of the survey to prevent impacts to individual birds that could begin nesting after the survey. • If bird nests (either passerine and/or raptor) are observed during the pre- construction survey, a disturbance-free buffer zone shall be established around the nest tree(s) until the young have fledged, as determined by a qualified biologist. The radius of the required buffer zone can vary depending on the species, (i.e., 75 to 100 feet for passerines and 200 to Incorporate

MM BIO-1c: Avoid Impacts to Sensitive or Listed Bats
The City of Santa Rosa shall ensure the following measures to avoid impacts to roosting bats are followed.
If initial ground disturbance occurs during the bat maternity roosting season (May 1 through August 31), a qualified biologist shall conduct a bat habitat assessment of trees within 100 feet of the Project site. The assessment shall evaluate the trees for suitable entry points and roost features, and shall provide focused daytime surveys for day-roosting bats. If the biologist determines there is potential for maternity roosting bats to be present within 100 feet of construction areas, nighttime emergence surveys may be performed to determine if maternity roosting bats are present.
If bat maternity roosts are present, the biologist shall establish an appropriate exclusion zone around the maternity roost. Removal of trees that potentially support a bat maternity roost should only occur between September 1 and October 15, after the young have learned to be self-sufficient but before hibernation. Trees supporting bats should not be removed while bats are hibernating between October 15 and March 15 or otherwise while bats are present.
If a special-status bat species is found, or if suspected day roosts for special- status bats are identified, then the qualified biologist shall identify suitable measures for avoiding impacts to roosts to achieve the performance standard of ensuring bat species have relocated prior to demolition or removal of the roosting structure. Measures shall include, at a minimum, phased removal of trees where selected limbs and branches not containing cavities are removed using chainsaws on the first day, with the remainder of the tree removed using chainsaws or other equipment on the second day after all bats have left the roost.

that appropriate actions to protect cultural and tribal cultural resources are taken, as described in more detail below.
1. Protection and Preservation;
2. Pre-construction data recovery; and
3. Construction Monitoring
Protection and Preservation
The preferred treatment of an archaeological resource is protection and preservation. Protection can be achieved by either avoidance (not developing within the boundaries of an archaeological resource), by covering an archaeological resource with geo-fabric and sufficient fill to protect it during and after construction, or by reducing/restricting development within the boundaries of a resource.
Pre-Construction Data Recovery
For significant resources that are not protected and preserved in place, data recovery within the sensitive area to be affected by the Project is necessary.
Data recovery must be performed by qualified archaeologists using standard archaeological techniques. Data recovery must include processing and analysis of recovered cultural materials using appropriate archaeological methods, and preparation of the recovered materials for permanent disposition (e.g., re-burial in a location that will be identified in collaboration with FIGR and Lytton and that would be protected in perpetuity) per the requirements of the Archaeological and Tribal Cultural Resources Treatment Plan. Prior to any ground disturbing activities, for all areas of the project site that have not undergone previous subsurface investigations, one of the following Extended Phase I investigation methods shall be conducted: (1) shovel test pits/shovel probe, (2) backhoe trenching, or (3) hand augering. The archaeologist shall determine the appropriate method and provide the scope of work to FIGR and Lytton for a 14- day comment period. Any resources identified during subsurface testing shall be treated in accordance with the Archaeological and Tribal Cultural Resources Treatment Plan.
Construction Monitoring
A program of archaeological monitoring shall be instituted for ground-disturbing activities associated with the area outlined in the Cultural Resources Summary prepared for the Project by Tom Origer & Associates (Origer & Associates 2020).
Monitoring shall be performed by a qualified archaeologist and may also include a Native American monitor and will consist of directly watching the excavation, grading, trenching, and other earth-moving processes. Monitoring shall continue on a daily basis until the depth of excavation has been reached at which resources could not be present. This will be determined by the monitoring archaeologist based on observed soil conditions.

The City shall ensure that if potential unanticipated archaeological or tribal cultural resources are uncovered during construction, the Applicant and its contractor shall halt work, and workers shall avoid altering the materials and their context. Project personnel shall not collect cultural materials, examples of which are provided in the following description. Prehistoric archaeological site indicators include: obsidian and chert flakes and chipped stone tools; grinding and mashing implements (e.g., slabs and handstones, and mortars and pestles); bedrock outcrops and boulders with mortar cups; and locally darkened midden soils. Midden soils may contain a combination of any of the previously listed items with the possible addition of bone and shell remains, and fire affected stones. Historic period site indicators generally include: fragments of glass, ceramic, and metal objects; milled and split lumber; and structure and feature remains such as building foundations and discrete trash deposits (e.g., wells, privy pits, dumps).
A qualified archaeologist and representatives of FIGR and/or Lytton shall be retained by the Applicant to investigate the find and make recommendations as to treatment and handling of those resources. If the find potentially qualifies as a historic resource, unique archaeological resource, or tribal cultural resource under CEQA, all work must remain stopped in the immediate vicinity to allow the archaeologist and tribal representatives to evaluate any materials and recommend appropriate treatment.

preferable. In considering any recommended measures proposed by the archaeologist, FIGR, or Lytton, the City shall determine whether avoidance is feasible in light of factors such as the nature of the find, Project design, costs, and other considerations. If avoidance is infeasible, other appropriate measures as determined by the City upon consideration of recommendations by the archaeologist, FIGR, or Lytton (e.g., data recovery or protection in place) shall be instituted. A buffer area around the resource would be established by a qualified archaeologist and tribal representative to ensure that no further damage to a resource would result. Work may then proceed on other parts of the Project while mitigation for these resources is being carried out.
MM CR-3: Treatment of Human Remains, Associated Grave Goods, or Items of Cultural Patrimony
Should human remains, associated grave goods, or items of cultural patrimony be encountered during Project construction, the following procedures shall be followed as required by Public Resources Code Section 5097.9 and Health and Safety Code Section 7050.5.
If human remains are encountered, no further excavation or disturbance of the site or any nearby area shall occur until the Sonoma County Coroner has made the necessary findings as to origin, in accordance with Health and Safety Code 7050.5. In accordance with Public Resources Code 5097.98 if the coroner believes the human remains to be those of a Native American, he or she shall contact, by telephone, within 24 hours, the Native American Heritage Commission. The Native American Heritage Commission shall immediately notify the Most Likely Descendent (MLD) or Descendants. The Descendent shall inspect the site of the discovery and may recommend the means for treating or disposing, with appropriate dignity, the human remains and any associated grave goods. The Descendants shall complete their inspection and make their recommendation within 48 hours of their notification by the Native American Heritage Commission. The remains shall not be damaged or disturbed by further development until the landowner has discussed and conferred with the MLD regarding their recommendations.

MM HWQ-1: Manage Construction Dewatering
If construction dewatering is required, the City shall require the Applicant and its contractor to evaluate reasonable options for dewatering management that would avoid discharging to a local surface water or storm drain. The following management options shall be considered:
• Reuse the water on-site for dust control, compaction, or irrigation. • Retain the water on-site in a grassy or porous area to allow infiltration/evaporation.
• Discharge (by permit) to a sanitary sewer.
If discharging to the sanitary sewer, the Applicant shall comply with a one-time discharge permit or other type of approval requiring, as necessary, measures for characterizing the discharge and ensuring filtering methods and monitoring to verify that the discharge is compliant with the City’s local wastewater discharge requirements.
If discharging to a local surface water or storm drain, the Applicant shall obtain coverage under NCRWQCB Order No. R1-2009-0045, Waste Discharge Requirements for Low Threat Discharges to Surface Waters in the North Coast Region. The Applicant shall submit permit registration documents to the NCRWQCB, including development of a Best Management Practices/Pollution Prevention Plan to characterize the discharge and to identify specific measures to control the discharge, such as sediment controls to ensure that excessive sediment is not discharged, and flow controls to prevent erosion and flooding downstream of the discharge. The City shall ensure that the Applicant oversees implementation of the Best Management Practices/Pollution Prevention Plan during construction dewatering activities, including visual inspections and ensuring overall compliance.
