BIO-1 In order to avoid potential impacts to nesting birds in conformance with the Migratory Bird Treaty Act and California Fish and Game Code during all phases (Phase I, Phase IIA, Phase IIB, and Phase IIC) of the project, a qualified biologist will conduct a nesting bird survey within 1 week prior to ground -disturbance activities.
Avoidance will involve the period from approximately February 1 to August 31, which covers the breeding season for most birds that may occur in the project area.
The survey shall cons ist of full coverage of the proposed disturbance footprint as well a 300 -foot buffer. If no active nests are found, no additional measures are required. If active nests are found, the nest locations shall be mapped by the biologist using Global Positioning System (GPS) equipment. The nesting bird species and, to the degree feasible, the nesting stage (e.g., incubation of eggs, feeding of young, near fledging) will be documented. The biologist shall establish a no-disturbance buffer around each active nest. The buffer will be determined by the biologist based on the species present and surrounding habitat. No construction or ground-disturbance activities shall be conducted within the buffer until the biologist has determined the nest is no longer active and has informed the construction supervisor that activities may resume.
CUL-3 In order to lessen direct and indirect impacts related to archaeological evidence of Chinatown’s history that is around the project site or at the Old Magnolia Avenue Trolley Line and Refuse Dump, and any unknown Native American artifacts, all ground-disturbing activities during all construction phases of the project shall be monitored by a qualified archaeologist meeting the requirements of the Secretary of the Interior. In the event that the archaeological monitor identifies a potentially PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices significant site, the monitor shall secure the discovery site from further impacts by delineating the site with staking and flagging, and by diverting grading equipment away from the archaeological site. Following notification to the City of Riverside (City), the archaeological monitor shall conduct investigations as necessary to determine whether the discovery is significant under the criteria listed in the California Environmental Quality Act and the environmental guidelines of the City.
If the discovery is determined to be not significant, grading operations may resume and the archaeological monitor shall summarize the findings in a letter report submitted to the City following the completion of mass grading activities. The letter report shall describe th e results of the on -site archaeological monitoring, each archaeological site observed, the scope of testing conducted, results of laboratory analysis (if applicable), and conclusions. The letter report shall be completed prior to the release of grading bonds. Any artifacts recovered during the evaluation of resources shall be curated at a facility approved by the City.
Pursuant to Public Resources Code Section 5097.99, in the event Native American artifacts are discovered, work within the area of the discovery shall stop and the City shall consult with representatives of the Native American community to ensure the respectful treatment of Native American artifacts.
For the cultural prehistoric/historic resources that are determined to be significant, alternate means of achieving mitigation shall be pursued. In general, these forms of mitigation include the following:
1. Site avoidance by preservation of the archaeological site in a natural state in open space, or in specific open space easements
2. Site avoidance by preservation through capping the site and placing landscaping on top of the fill
3. Data recovery through implementation of an excavation and analysis program
4. A combination of one or more of the above measures.
CUL-5 In addition to MM CUL -3 requiring all ground -disturbing activities during all c ons t ruc t ion p h as e s of t he p r oje c t t o b e monit or e d b y a q ual ifi e d ar c hae ol og is t , RCH, in coordination with the City, will notify local tribes 30 days prior to ground - disturbing activities, allowing the local tribes to monitor grading and ground - disturbing activities along with RCH's qualified archaeological monitor.
HAZ-1 Prior to demolition activities in Phase I, Phase IIA, and Phase IIB of the project, a lead-based paint and asbestos survey shall be conducted. Should lead-based paint PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices or asbestos- containing materials be identified during survey, abatement of the same will be accomplished in accordance with local, state, and federal guidelines.
HAZ-2 Prior to grading and/or subsurface work for Phase I, Phase IIA, Phase IIB, and Phase IIC of the project, air monitoring for volatile organic compounds (VOCs) shall be conducted to determine whether subsurface contamination will affect construction activities. If VOC levels are above those allowed for worker safety and environmental compliance, Riverside Community Hospital (RCH) shall retain qualified personnel to train RCH employees and/or contractors, remediate existing VOC levels, and prevent exposure to RCH customers and employees/contractors through monitoring and remediating impacted materials, proper use of personal protective equipment, and utilizing best management procedures.
NOI-1 In order to reduce impacts related to heavy construction equipment moving and operating on-site during all phases (Phase I, Phase IIA, Phase IIB, and Phase IIC) of demolition, grading, and construction, prior to issuance of grading permits mitigation measures shall be incorporated by the City of Riverside) as conditions on permits. Examples of measures to be required by the City are as follows:
• All construction equipment, fixed or mobile, shall be equipped with properly operating and maintained mufflers.
• Construction noise reduction methods, such as shutting off idling equipment, maximizing the distance between construction equipment staging areas and occupied sensitive receptor areas, and using electric air compressors and similar power tools rather than diesel equipment, shall be used. • During construction, stationary construction equipment shall be placed such that noise is directed away from or shielded from sensitive noise receivers.
During construction, stockpiling, and vehicle staging areas shall be located far from noise-sensitive receptors.
• The project shall be in compliance with the City's Municipal Code: Construction shall occur between the hours of 7:00 a.m. and 7:00 p.m. on weekdays, and between 8:00 a.m. and 5:00 p.m. on Saturdays. Construction hours, allowable workdays, and the phone nu mber of the job superintendent shall be clearly posted at all construction entrances to allow surrounding property owners and residents to contact the job superintendent.
NOI-2 If surface parking or parking structures are proposed during Phase IIA, IIB, or IIC of the project, the project proponent shall retain an acoustical specialist to conduct PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices an analysis of noise effects from the proposed parking facilities at nearby noise - sensitive land uses, and to provide mitigation measures that will reduce noise levels to below 60 A -weighted decibels (dBA) or less at the property line and will not otherwise result in the project exceeding relevant noise standards at nearby noise- sensitive land uses (e.g., recreation, residential). Examples of mitigation measures are as follows: requirement of pavement treatments to reduce or eliminate tire squeal, admini strative measures such as restricted speed limits and active enforcement thereof, or restricted parking hours.
NOI-3 Because heating, ventilation, and air conditioning HVAC) equipment, boilers, and generators can generate noise that could affect surrounding sensitive receptors for all phases (Phase I, Phase IIA, Phase IIB, and Phase IIC) of the project if not placed inside buildings or enclosures or otherwise shielded from receptors, and because t h e d e t a i l s , s p e c i fi c a t i o n s , a n d l o c a t i o n s o f t h e s e f a c i l i t i e s i s n o t k n o w n y e t , t h e project proponent shall retain an acoustical specialist to review project construction -level plans at every phase (Phase I, Phase IIA, Phase IIB, and Phase IIC) of the project to ensure that the equipment specifications and plans for HVAC, central plant, and emergency generator equipment incorporate measures, such as the specification of quieter equipment or provision of acoustical enclosures, that will reduce noise levels to below 60 dBA or less at the property line and will not otherwise result in the project exceeding relevant noise standards at nearby noise- sensitive land uses (e.g., recreation , residential). Prior to the commencement of construction for all phases (Phase I, Phase IIA, Phase IIB, and Phase IIC) of the project, the acoustical specialist shall certify in writing to the City that the equipment specifications and plans incorporate m easures that will achieve the relevant noise limits.
TRA-5 14th Street and Magnolia Avenue / Market Street, prior to issuance of certificate of occupancy for Phase IIA, a second westbound left-turn lane shall be provided at the intersection of 14th Street and Magnolia Avenue / Market Street, as well as signal operation modification to provide right -turn overla p for the northbound approach. Additional right-of-way shall be dedicated on 14th Street at Market Street to accommodate the proposed turn lanes. If acquisition of off -site right-of-way is necessary, the applicant shall make a good faith effort to acquire the right-of-way needed to accomplish the improvement.
UTL-1 Prior to issuance of building permits, the applicant shall complete a Construction Waste Recycling Plan and submit the plan to the Riverside County Waste Management Department (RCWMD) for approval. The plan will identify and PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices estimate the materials to be recycled during construction and demolition activities and will specify where and how the recyclable materials will be stored on the site.
Compliance with the plan will be a requirement in all construction contracts. The RCWMD-approved plan will be attached to all construction plans and distributed to all construction contractors. Once construction is complete, the applicant will be responsible for preparing a Waste Recycling Report that demonstrates that the project recycled a minimum of 50% of its construction and demolition waste. The waste recycling report must be submitted to and approved by the RCWMD prior to issuance of occupancy permits. Since this project will be developed in phases over time, review and approval of Cons truction Waste Recycling Plans and Waste Recycling Reports can be submitted by phase or building. However, for each Construction Waste Recycling Plan submitted and approved, a corresponding Waste Recycling Report should also then be submitted for approval.
UTL-2 Prior to issuance of building permits, the applicant shall submit building plans to the RCWMD and obtain approval from the RCWMD for compliance with the Riverside County Design Guidelines for Refuse and Recyclables Collection and Loading Areas, which include specifications for recyclable storage space, location and access, signage, protection and security, compatibility, and overall compliance with federal, state, and local laws.
