WHEREAS, the City of Santa Ana desires to widen and improve Bristol Street, between Warner Avenue and Memory Lane, from a four-lane, undivided arterial to a six-lane, divided arterial street, and to modify several intersections of Bristol Street with crossing arterial streets, in order to improve the vehicular traffic carrying capacity, efficiency and safety, aesthetics, and pedestrian circulation of this major thoroughfare; and WHEREAS, a Final Environmental Impact Statement/Report has been prepared for the project; and WHEREAS, the Planning Commission, after duly a noticed public hearing, has recommended that the City Council certify the Final Environmental Impact Statement/Report and approve the project; and WHEREAS, the city Council has held a duly noticed public hearing on the proposed project; NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF SANTA ANA AS FOLLOWS: The city Council hereby certifies that the Final Environmental Impact Statement/Report for the project has been completed in accordance with the requirements of the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), and is therefore considered equivalent to and a substitute for a Final Environmental Impact Report. The city Council further certifies that the Final Environmental Impact Statement/Final Environmental Impact Report (FEIS/FEIR) for the project was presented to the City Council, and that the City Council reviewed and considered the information in the FEIS/FEIR for the project prior to approving the project. The mitigation measures identified in the FEIS/FEIR for the project are incorporated into the project as conditions that will be included in the final street RESOLUTION NO. 90-113 PAGE TWO improvement plans and carried out throughout the right- of-way acquisition, relocation, construction, and post- construction periods. The city Council hereby finds that, as to each potential significant environmental effect of the project, the corresponding mitigation measures avoid or substantially lessen such significant effect for the reasons specified in Exhibit "A" attached hereto and incorporated herein. The City Council further finds that, to the extent significant environmental effects of the project are not reduced to a level of insignificance, such effects are acceptable due to the overriding considerations set forth in said Exhibit "A," and that alternatives to the project identified in the FEIS/FEIR are either infeasible or would result in more significant environmental effects and are, therefore, rejected. In order to assure the implementation of the mitigation measures identified in the FEIS/FEIR for the project, the City Council hereby approves, adopts, and directs the administrative staff of the City to carry out the Mitigation Monitoring/Reporting Program set forth in Exhibit "B," attached hereto and incorporated herein. ADOPTED this 17th day of December , 1990__. ATTEST: J~fce C. Guy / Clerk of the Counci~ Daniel 'H. Yo~g Mayor COUNCILMEMBERS: Young Aye Pulido Aye Acosta Aye Griset Ay~ McGuigan Ay~ Norton Richardson Ay~ APPROVED AS TO FORM: CERTIFICATE OF ORIGINALITY State of California County of Orange I, JANICE C. GUY, Clerk of the Council, do hereby certify the attached Resolution ~ //5 to be the original resolution adopted by the City Council of the City of Santa Ana on -/7- 73 City of Santa Ana Date ,067 EXHIBI~ "A" ENVIRONMENTAL F: INGS AND STATEMENT OF OVERRIDING CONSIDERATIONS FOR THE BRISTOL STREET WIDENING PROJECT ENVIRONMENTAL FINDINGS The Final Environmental Impact Report for the project identified the following significant, or potentially significant, environmental effects of the project, under the following general headings. With respect to each of the significant or potentially significant effects, the findings required by Section 21081 of the California Environmental Quality Act (CEQA) and Section 15091 of the CEQA Guidelines, and the rationale for each of the findings, are set forth below. A. Air Quality Significant Effects Short-term increases in local emissions would occur during construction of the proposed improvements, which could be considered a nuisance by local residents, pedestrians, shoppers, etc., who are present during construction operations. Such emissions would involve exhaust from construction equipment, fugitive dust from grading activities and vehicular exhaust from motor vehicles of the construction crew and the vehicles used to transport the construction equipment. Minor long-term increases in emissions of nitrogen dioxides would occur because of improved traffic flow and higher operating speeds. Findings The following measures have been incorporated into the project, which, if properly implemented, would avoid or substantially lessen the air quality effects to a level of insignificance: South Coast Air Quality Management District (SCAQMD) Rule 403 will be adhered to, ensuring the cleanup of construction related dirt on approach routes to the site. Adequate watering techniques will be employed to partially mitigate the impact of construction-generated dust particulates. 068 Construction equipment will be properly maintained and serviced to minimize exhaust emissions. Consideration will be given to the provision of convenient bus shelters and turnouts along Bristol Street to encourage the use of public transportation. The use of energy efficient lighting along Bristol Street will be considered to reduce emissions at the power plant serving the area. (AQMP control measure Nil.) Traffic signals along Bristol Street will continue to be synchronized. (AQMP control measures K2.) Construction activities will be halted during Stage One and Stage Two smog alerts. Rationale The construction-period emissions projections are typical for this type of project, and are usually considered insignificant, since they are short-term. The projected increase in emissions of nitrogen-dioxide "with project" is only one percent more than projected "no-project" conditions. Watering down areas where the ground surface is disturbed will minimize fugitive dust generation. Proper maintenance of equipment and vehicles will reduce exhaust emissions due to more efficient burning of the fuel. As people increase their use of public transit, the increase in area-wide vehicular trips is somewhat reduced, helping to lessen the increase in vehicle emissions. Energy-efficient street lighting reduces demand at distant power facilities, helping to minimize emissions at those power facilities. Synchronization of traffic signals improves traffic flow, lessening congestion and allowing vehicles to operate at a higher efficiency, with lower emissions of carbon monoxide and hydrocarbons. Noise Significant Effects Short-term increases in local noise levels would occur during construction of the proposed improvements, which could be perceived as nuisance noise by residents, pedestrians, shoppers, etc. during construction operations. A widened roadway will result in a wider dispersion of traffic noise along the roadway, potentially resulting in noise level increases in excess of federal and State standards for numerous sensitive receptors, along the corridor, if adequate sound barriers cannot feasibly be provided because of access and sight distance requirements. Findings The following measures have been incorporated into the project, which, if properly implemented, will avoid or substantially lessen the noise effects, to'a level of insignificance. Replacement of existing barriers that are removed to widen the street by barriers at least six feet high. Construction of six-foot block walls on corner lots with access to cross streets, where adequate vehicular sight distances can be maintained. Construction of solid sound barriers adjacent to school playgrounds and athletic fields, where determined feasible in consultation with school district officials, to meet federal exterior noise criteria. Construction of six-foot walls to shield residential rear yards, where such rear yards face Bristol Street. Construction of six-foot walls at second-line receptor property lines, to meet the 67 Leq federal criteria. Construction activities will take place only during the hours specified in the City of Santa Ana Noise Control Ordinance to reduce noise impacts during more sensitive time periods. All construction equipment, fixed or mobile, shall be equipped with properly operating and maintained muffler exhaust systems. Stationary equipment shall be placed such that emitted noise is directed away from sensitive noise receivers such as residential areas. Stockpiling and vehicle staging areas shall be located as far as practical from occupied dwellings. 10. Every effort will be made to create the greatest distance between nois :ources and receptors during construction. 070 11. The noisiest construction operations will be arranged to occur together in the construction program to avoid continuing periods of greater annoyance. Rationale The predicted noise levels are based upon the most current analytical methods, using projected traffic volumes and roadway geometry as a basis for determining existing and future noise contours and the height of solid barriers needed to reduce predicted noise levels to less than the FHWA significance threshold. The use of solid barriers to effectively attenuate noise has been proven in many different locations, and is often the most feasible method, when large spatial separations between the noise source and the sensitive receptor cannot be provided. The installation of solid walls along the widened street right- of-way can be readily accomplished, using standard construction techniques. The City's Noise Ordinance limits the permissible hours of construction to workday and Saturday periods when the noise environment along Bristol Street is most pronounced and the construction activities will, therefore, be somewhat masked within the ambient noise levels. Proper maintenance of construction equipment and vehicles and sensitive staging of equipment and activity rises with respect to nearby residential uses, can reasonably be expected to further minimize the short-term construction noise to an acceptable level. Housing Displacement Significant Effects Acquisition of needed right-of-way and completion of the proposed improvements would result in the removal of 163 housing units (including both single and multi-family units). Removal of these housing units would displace approximately 538 residents (assuming an average household size of 3.3) who would need comparable, decent, safe and sanitary replacement housing in a nearby neighborhood of their choice. A proper and adequate residential relocation program will be complicated by the mixed Hispanic, Asian, and Caucasian ethnicity of the displaced households and by the expected high percentage of lower income households involved. As discussed in the Draft Relocation Study, the City will retain Spanish and Vietnamese- speaking relocation agents and interpreters to facilitate relocation of these affected minority groups. 071 Findings The following measures have been incorporated into the project, which, if properly implemented, would substantially lessen the housing displacement effects to an acceptable, though significant, level. All displaced residents will receive relocation assistance from the City of Santa Ana, in accordance with the Department of Transportation, Federal Highway Administration, Uniform Relocation Assistance and Real Property Acquisition Regulations for Federally Assisted Programs (49 CFR, Part 24), March 1989 (a.k.a. the Uniform Act), and California Department of Transportation guidelines. Assistance will be provided by relocation agents with appropriate foreign-language skills and will include information on the availability and prices of homes for sale and for rent that are comparable, decent, safe and sanitary. Relocation payments will also be available to help eligible displaces, in the form of paying certain costs and expenses involved in moving, purchasing, or renting replacement dwellings. Last resort housing benefits will also be provided to cover situations where displaces cannot be relocated due to the lack of available comparable replacement housing, or when their anticipated replacement housing payments would exceed the limits of the standard relocation payments program. "Special need" displaced households will be identified in the final relocation plan, along with any extraordinary relocation assistance that will be provided. Rationale Although the short-term effects of being displaced will be significant for most, if not all displaced households, the above-described relocation benefits are intended to ensure that sufficient and acceptable replacement housing is provided for all types of affected households. The City of Santa Ana has a relocation policy to provide relocation assistance and is also required to provide these benefits as a condition of receiving federal funds for this project. The City cannot complete the necessary right-of-way acquisition unless all displaced households are adequately relocated. Sufficient replacement housing is expected to be available within this general area, based on current residential vacancy rates and an increasing supply of housing that will result from projects currently planned or under construction in Santa Aha and immediate surrounding areas. While the effects of relocation 072 will be uncomfortable and significant in the short-term, it is reasonable to expect that displaced households will eventually settle into their replacement housing and adapt satisfactorily to their new neighborhood and living conditions. Many of the displaced low-income households will be relocated to newer, safer, and more stable housing than they currently occupy (many of which are in disrepair, are aged, and which lack certain modern conveniences), a long4erm benefit for these households. Business Displacement Significant Effects Acquisition of the needed right-of-way and completion of the proposed improvements would result in the displacement of up to 101 private business firms in the project area. Most of the businesses are small, consisting of less than ten employees. This could result in the temporary or even permanent loss of employment and income for the estimated 606 employees that are involved (assuming an average of six employees per business). Many of the potential displaced businesses rely heavily on local patronage, due to neighborhood identification and ethnic ties. These businesses would have greater difficulty in successfully relocating to a new location. Some of these firms may be forced to close permanently as a result. Findings The following measures have been incorporated into the project, which, if properly implemented, will lessen the business displacement effects to an acceptable, though significant, level. The City will comply with the most current State and Federal Uniform Relocation Acts, as amended, to assist businesses that are displaced by the project. Relocation assistance available to displaced businesses, pursuant to the Uniform Act, includes the following: A displaced business is entitled to reimbursement for the actual reasonable costs of moving personal property, searching for a replacement location, storage, utilities, reconnection, licenses and permits, and other related items. bo Costs of reestablishing a displaced business involving repairs, property improvements, installations, feasibility surveys, advertising, professional leasing services, increased operational costs, impact fees, etc., will be reimbur.sed, up to a maximum of $10,000. If the business cannot be relocated without substantial loss of patronage (net annual earnings), a fixed payment may be made "in lieu of' actual moving expense. However, this fixed payment cannot exceed $20,000. If the payment is for "Loss of Goodwill" under California Law, it should be noted that federal funds cannot participate in this payment type. The Project Area Committee (PAC) will address various alternatives to keep displaced businesses within the immediate project area. Such alternatives may include establishment of a small shopping mall within the Bristol Street project area. Rationale The relocation benefits described above are eXpected to cover most, if not all, of the costs of relocating displaced businesses, so that the affected businesses do not suffer financial loss or ruin. In some instances, however, the business owner may choose not to relocate, but to simply go out of business. In other cases, the displaced business may suffer from the inability to reestablish strong neighborhood identification at the new location and could, therefore experience a significant decline in business activity. The Project Area Committee will, however, be advising the City Council and Redevelopment Agency on ways to retain displaced businesses within the Bristol Street corridor, such as the establishment of a small shopping mall for these firms, to avoid such significant effects. Neighborhood Character and Minority Groups Significant Effects The net effects of the proposed street widening with respect to neighborhood character and minority groups would be most evident in terms of physical appearance and a reduced influence of Hispanic and Asian minorities as components of the local business community. These are unavoidable consequences of any street widening alternative, due to the right-of-way acquisition requirements and the fact that Hispanic and Asian minorities are the largest components of the local population. The local citizen-based Project Area Committee (PAC), '073 074 established to provide direct community input into the planning of the proposed Bristol Street Corridor Redevelopment Project and this project, will address the minorities and small business relocation issues and provide recommendations to the City Council. Findings The following measures have been incorporated into the project, which, if properly implemented, will avoid, or substantially lessen, the effects on neighborhood character and minority groups, to an acceptable, though significant level. Prior to acquisition of right-of-way, the City of Santa Ana will evaluate the desirability of alternative dispositions of all remaining portions of full-take parcels. Where feasible within the development standards of the Zoning Ordinance and in accordance with the City of Santa Ana policy, such areas will be: ao assembled for redevelopment; sold to adjoining land owners; or landscaped, thus extending the 'public parkway by varying depths. Consideration will be given to placing existing overhead utility lines along the street underground as part of the proposed project. A coordinated theme will be developed for landscaping and improvements within the widened street right-of-way. All households and businesses that are displaced will receive relocation assistance from the City of Santa Ana, as previously described. Affected minority groups will be relocated to comparable neighborhoods, if so desired, within the City of Santa Ana and surrounding communities. In conjunction with City staff, the Project Area Committee (PAC) will address various alternatives to keep displaced businesses within the immediate project area. Such alternatives may include establishment of a small shopping mall within the Bristol Street project area. 075 Fo Rationale The redevelopment of the Bristol Street corridor is expected to result in many improvements to its physical character. This will occur through removal of aged and/or deteriorated buildings, signs, and structures and unsightly or underutilized properties, and their. replacement with an attractive landscape treatment, modern street lighting, and other street improvements of a more uniform appearance and higher quality, along with new buildings and developed sites that reflect the City's current development standards and the design objectives for the Bristol Corridor Redevelopment Project. The relocation benefits and assistance of the Project Area Committee will minimize the extent and severity of the displacement of local minority households and businesses, while providing the necessary funding to cover all of the relocation costs. Community Facilities Significant Effects Right-of-way requirements would result in the diminishment of site area at one public elementary school and one church, and would require displacement of two private preschools. The affected sites include: loss of front yard area at the Jose Andres Sepulveda School (not considered significant since the school district acquired this site from the City, with agreement that Bristol Street frontage would be donated to City for this project); the Southwest Learning Center/Preschool (private) would be displaced; 3. the Childrens Center/Preschool (private) would be displaced; the Lutheran Church at 1406 South Bristol Street would lose land along Bristol Street, requiring a reorientation of building and parking areas to meet City of Santa Ana zoning standards. Finding The following measures have been incorporated into the project, which, if properly implemented, will lessen the effects on community facilities to a level of insignificance. 076 Relocation assistance, in accordance with the State and Federal Uniform Relocation Acts, will be made available to the displaced preschools. Rationale The two preschools provide service to the local area, but this type of service is readily transferrable to many other areas, due to the pressing need throughout the entire region for child care services. The relocation benefits available to those two firms will enable them to relocate either within the Bristol Corridor or elsewhere, as desired. If either or both preschools relocate outside the project area, an opportunity for a new child care service in this area will exist, which could be accommodated on a number of vacant or underutilized sites that will exist following completion of right-of-way acquisition. Assessed Property Values Significant Effects Acquisition of needed right-of-way and removal of existing structures would reduce the amount of private property subject to assessment of local property taxes. The potential loss in annual property taxes is currently estimated at $322,300. This would be an adverse impact for those public agencies which receive property tax disbursements from the project area. The potential diminishment in property taxes will be somewhat recovered through redevelopment of remnant parcels and intensification of existing uses. Findings The following measures have been incorporated into the project, which, if properly implemented, would avoid or substantially lessen the effects on assessed property values. To reduce the loss of property tax revenues, remaining portions of full-take parcels will be evaluated for potential assemblage and redevelopment or for sale to adjoining land owners. This will keep the majority of the affected properties in private ownership and subject to assessment of property taxes, based on current property values. The City has adopted a redevelopment plan which encompasses the Bristol Street corridor and surrounding areas, which will provide the City Redevelopment Agency with tax increment financing abilities which will be used to revitalize this general tO 077 Ho area, resulting in long-term economic benefits, including increasing property tax revenues from property improvements. Rationale The development of remnant parcels not used within the widened roadway, with privately owned and improved building sites, will result in an efficient use of these land resources, which can be assessed for property taxes, thereby restoring and maintaining a stable property value throughout the Bristol Street corridor. The involvement and assistance of the Redevelopment Agency can facilitate and accelerate the process of assembling parcels, selling them to adjacent or other private property owners and reducing the costs of redevelopment through financial participation. These efforts are expected to help ensure a coordinated and effective redevelopment of the entire corridor, which will strengthen the economic base and local property values, resulting in the eventual replacement of lost property tax revenues due to right-of-way acquisition for this project, and providing a basis for long-term, gradual increases in the property tax base. Utilities Significant Effects No major disturbance of underground utilities is anticipated in order to construct the widened roadway; however, the exact depth and location of underground utilities along Bristol Street has not yet been determined. Since overhead utility lines will need to be relocated underground, the project may cause temporary disruption of electrical and telephone service to some area businesses and residences. It is possible to minimize any disruption to service during the construction process through coordination with local utility companies. Property owners will incur some costs for conversion from overhead to underground service. Findings The following measures have been incorporated into the project, which, if properly ~mplemented, will avoid or substantially lessen the effects upon utilities to a level of insignificance. Project plans and construction activities will be closely coordinated with local utility purveyors in order to make the necessary arrangements for the relocation of facilities and avoid or minimize any disruption to service. It is also recommended O78 that the utilities provide adequate notice to its customers of any service disruptions. Consideration will be given to the undergrounding of overhead electrical and telephone lines as part of the project. The City of Santa Ana's Public Works Director will coordinate closely with all agencies and companies which maintain underground or at-grade utility or energy facilities within the areas to be disturbed by project construction activities. Preliminary and final design plans will be made available to such agencies for review and comment. At least 48 hours prior to commencement of any excavation activities, the City will contact the Underground Service Alert to notify the affected utility/energy purveyors who can place their personnel at the excavation site to assist in the location of underground facilities during the exploratory digging immediately preceding excavation. In this manner, the risk of line rupture to natural gas, petroleum, and sewer facilities, which might release hazardous substances and odors into the air, can be minimized. Rationale. Relocation and/or undergrounding of overhead utility facilities is a very routine aspect of major street construction, such as the proposed project. The utility purveyors employ specialists who will be contacted by the City's engineers (or consulting engineers) during the final design of the proposed improvements to properly identify all affected utility facilities and to prepare strategies for safe relocation/undergrounding and for interim service, if needed. Advance notification to the various utility purveyors prior to commencement of construction and excavation will allow these companies to provide field personnel during construction to assist the contractor in locating, relocating, and undergrounding affected facilities, as appropriate, and in connecting interim service facilities as needed. Advance notice to utility customers of pending or possible service disruptions will enable affected customers to plan accordingly and to make whatever arrangements they feel are necessary to function adequately during that short-term disruption of utility service. Undergrounding of existing overhead electrical and telephone lines would reduce visual clutter in this corridor and help prevent damage to such facilities by removing them from direct public contact. 079 Circulation Significant Effects The construction activities required to widen the roadway will temporarily restrict traffic flow along Bristol Street. While the roadway will remain open to through traffic, the number of available travel lanes will probably be reduced during various phases of construction, thereby reducing the capacity and efficiency of the roadway. For this reason, the volume of traffic which Bristol Street can handle efficiently will be decreased during the period of project construction. Since this would result in an increase in travel time along Bristol Street, some motorists will probably choose to take an alternative route when convenient. Joint construction of~he proposed I-5 Freeway widening project would further increase traffic congestion on alternate routes throughout the general area. Access to property fronting along Bristol Street will also be intermittently disrupted as work progresses adjacent to individual parcels and temporarily blocks driveway access. Provisions will be made for interim access whenever necessary. Since construction of the project will be undertaken in phases, the disruption of circulation along the roadway will be reduced since only certain segments of the street would then be affected at any one time. In order to enhance traffic flow and minimize hazards, traffic control plans will be prepared prior to each step in the construction process. The disruption of traffic and restriction to access along Bristol Street during project construction could affect the mobility and responsiveness of emergency vehicles which commonly utilize the street. The fire department has indicated that Stations 1, 3, 4, 5, and 7 will be impacted during construction of the proposed project since these stations typically utilize Bristol Street in route to au emergency call. Similarly, police vehicles and ambulances commonly utilize Bristol Street as a travel route in emergency situations and, as a result, will be adversely impacted by any restrictions to travel caused by construction activities. Even though movement may be hampered by construction activities, Bristol Street will remain open to through traffic and access to property along the street will be maintained. Findings The following measures have been incorporated ihto the project, which if properly implemented, will avoid or substantially lessen the effects upon local circulation to an acceptable level of significance. If feasible, construction activities and lane closures will occur primarily during non-peak driving periods. 080 The police and fire departments will be notified of construction at least one month in advance, as to the particulars of the project (i.e., project time schedule, and areas to be disrupted, etc.). This action would give the police and fire departments sufficient time to notify its personnel of any significant impediments to traffic. The City will notify the police department at least 48 hours in advance of any turning changes. A minimum of three signs are required for each indicated change and/or prevention of movement. Construction will be staged so that only limited segments of the roadway are affected at any one time. So Traffic control plans will be prepared prior to each phase of construction. All traffic warning and control devices should comply to the provisions of the State of California Manual of Traffic Controls. o The Orange County Transportation District will be notified prior to the initiation of project construction so that arrangements can be made for alternative bus routes and interim bus stop locations, if necessary. Rationale The disruption to local traffic and circulation during the construction phase of this project will be unavoidable, but of limited duration, approximately 9 to 12 months per phase. Careful planning of each phase of construction, with respect to traffic control measures, can do much to minimize this disruption. It is possible to maintain up to 20,000 vehicles/day of through traffic, during construction, if lane controls, detours, construction staging, length of construction segments, construction scheduling, etc. is managed carefully. This will allow Bristol Street to continue to carry a large volume of traffic, helping to maintain local business activity and ensuring satisfactory access to local homesites while allowing for substantial commuter traffic. Advance notice to motorists via signs, newspaper ads, etc. will provide the motoring public with the ability to plan their trips through the Bristol Street corridor, and make appropriate changes in their trip schedules, trip routes, or mode of transport, such as ridesharing to reduce the overall number of vehicles on the local roadways during the departments, the local ambulance companies, and the Orange County Transit District will enable these critical service agencies to plan 14- 081 alternate routes and schedules, as needed to provide satisfactory and timely service during the periods when Bristol Street traffic flow is restricted by construction activities. II. STATEMENT OF OVERRIDING CONSIDERATIONS The FEIS/FEIR concludes that the proposed project would result in certain significant and adverse environmental effects, which are unavoidable, even after incorporation of all feasible mitigation measures. Specifically, the proposed project would result in significant (short-term) adverse effects upon households and businesses that are displaced to accommodate the required right-of-way for the widened street and parkways. For such significant effects, the City Council of the City of Santa Ana has balanced the benefits of the proposed project against these unavoidable environmental impacts, in determining whether or not to approve the project. In this regard, the City Council of the City of Santa Ana finds that these unavoidable significant effects upon local households and businesses are acceptable within the meaning of Sections 15092 and 15093 of the California Environmental Quality Act (CEQA) Guidelines, for the following reasons. The completion of the proposed roadway and intersection improvements would significantly improve the traffic carrying capacity, safety, and efficiency, pedestrian circulation, and visual quality of the affected Bristol Street corridor. These improvements will reduce the current and projected levels of traffic congestion along this street, to acceptable levels. The reduction in traffic congestion will reduce vehicle emissions of carbon monoxide and hydrocarbons, a positive effect on local air quality. The roadway capacity enhancement, along with the intersection improvements, bus turnouts, drainage improvements, traffic signal synchronization, prohibition of on-street parking and cul-de-sac of several intersecting local streets will significantly improve the flow of traffic, reducing delays and the related negative effects on personal productivity currently experienced by the impacted motorists. The removal of numerous aged, deteriorated and unsightly buildings and structures currently found along the roadway, will facilitate the planned redevelopment of this Bristol Street corridor in a comprehensive, integrated and productive manner, helping to stabilize and strengthen the economic base in this part of Santa Aha. All of these effects will positively benefit the entire community and outweigh the significant short-term effects on displaced households and businesses. 082 Archaeological Resources Significant Effects Excavation activities to remove old roadway surface and prepare the new roa0way surface, could potentially disturb buried remnants of historical or prehistorical artifacts. Finding The following measure has been incorporated into the project, which, if properly implemented, will avoid or substantially lessen the potential impacts on archaeological resources to a level of insignificance. If potential archaeological resources are encountered during grading, all work will be halted in that particular location until a qualified archaeologist can evaluate the significance of the recovered materials. Rationale Although the potential for uncovering buried archaeological artifacts is considered very low in this long-urbanized, built environment, the grading contractor's awareness of this concern and direction to halt work when unusual materials are uncovered, will enable a qualified specialist to examine and evaluate the material and to properly dispose of it, in accordance with the standards of the professional archaeological community. This will adequately preserve any significant resources that may be found. Light and Glare Significant Effects The installation of new street lighting fixtures could result in nuisance glare effects onto nearby residential sites. Finding The following measure has been incorporated into the project, which, if properly implemented, will avoid or substantially possible light and glare effects, to a level of insignificance. Consideration will be given to the selection of new street lighting fixtures which have cut-off shields to minimize light and glare nuisances for residential properties adjoining Bristol Street. 0S3 Rationale The illumination patterns and levels of intensity for street lighting fixtures are provided by the manufacturers of these products. With this information, and knowledge of the location and distances to nearby residential sites, light "cut- off' shields can be designed and retrofitted onto the light fixture, which will provide a solid barrier that will prevent the illumination from 'reaching the nearby residential sites, thus preventing any possible nuisance glare from the street lighting. L. Aesthetics Significant Effects Acquisition of right-of-way and construction of the proposed street improvements will result in a significant changes in the physical appearance of the Bristol Street corridor, including numerous remainder parcels and an increase in vacant sites. Existing landscaping along the street frontage and along the banks of Santiago Creek will be removed. Finding The following measures have been incorporated into the project which, if properly implemented, will avoid or substantially lessen the aesthetic effects to a level of insignificance. Consideration will be given to replacing existing overhead utility facilities with underground facilities, to reduce visual clutter along the improved roadway. A consistent theme will be developed for landscaping and other proposed improvements within the widened roadway. Consideration will be given to the implementation of a xeriscape landscaping program to reduce water demand and landscaping maintenance costs. Prior to acquisition of right-of-way, the City of Santa Ana will evaluate the desirability of alternative dispositions of all remaining portions of full-take parcels. Where feasible within the development standards of the Zoning Ordinance, and in accordance with the City of Santa Ana policy, such areas will be: assembled for redevelopment; sold to adjoining land owners; or landscaped, thus extending the public parkway by varying depths. O84 Rationale The development and installation of a consistent theme of landscaping and street improvements, within the center median and within the parkways along both sides of the street, will provide a more unified and attractive image for this corridor than presently exists. Use of xeriscape landscape techniques and' materials will reduce the costs of maintaining this landscaping, a fiscal benefit to the City and its taxpayers. Assemblage of adjoining remnant parcels into larger developable sites will facilitate the redevelopment of these vacant or underutilized sites with high quality, aesthetically integrated uses, which can meet or exceed the City's development standards and design objectives for the City's Bristol Street Corridor Redevelopment Plan. Sale of remnant parcels to adjoining land owners will allow those property owners to expand their existing uses and will return that land to private use, freeing the City from maintenance responsibility and restoring the land to the assessable property tax rolls. Landscaping of these remnant parcels will increase the amount of landscaping in the proposed parkways along both sides of the new street right- of-way; a significant visual benefit which will also provide increased opportunity for pedestrian amenities such as walkways and seating areas. Such added landscaping would also provide a deeper and more pleasant buffer to adjoining residential properties along the right-of-way. Seismic Hazards Significant Effects The project area is located in a seismically sensitive region, with potentially significant earthquake-induced ground shaking along the street, and potentially significant subsidence within the Santiago Creek. A major earthquake event could, therefore, result in the collapse of numerous unstable ground surface-level structures and could loosen the structural support for the Santiago Creek bridge. Finding The following measures have been incorporated into the project which, if properly implemented, would avoid or substantially lessen the potential for damage due to a major earthquake event, to a level of insignificance. As part of the engineering and preparation of design plans, structural and soils engineers will be retained to determine the structural stability of the Santiago Creek Bridge, with regard to a potential subsidence event. These assessments will include recommendations, if needed, to provide adequate structural support for the bridge. :085 Consideration will be given to installing and replacing surface level structures such as street lights, traffic signals and utility poles, with structures that have extensive subsurface footings that reach stable material. Rationale Modern soils and structural engineering practices are able to identify the probability and expected extent of changes in ground conditions, such as subsidence, due to seismic events. A soils study of the Santiago Creek streambed, surrounding the bridge supports area, will enable soils and structural engineers to determine whether the existing bridge structure was designed adequately to withstand the most probable seismic event and to recommend further structural enhancements as may be needed, which could be installed jointly during the bridge widening phase of the proposed project. A soils study will also be performed for the rest of the affected segment of Bristol Street. This study will also provide sufficient data with which to determine the most appropriate structural characteristics of the various new and replaced ground-level street improvements and traffic control facilities. The costs vs. benefits of any extraordinary structural measures that may be identified can also be determined so that funds are not allocated to unusual structural supports for such non-critical facilities (compared to earthquake- protection for a hospital or school classroom). Erosion and Water Quality Significant Effects Construction of the proposed street improvements will temporarily expose the ground surface to the forces of wind and possibly water movement, if conducted during a rainstorm. Also, construction of the widened Santiago Creek Bridge during the rainy season could generate debris piles that would add to the sediment run-off that would result from stormwater flows along the creek. Uncontrolled sedimentation, whether from street cnnstrnction run-off or within the stormwater flows along Santiago Creek, contribute to the pollution of downstream waters, which receive this mn-off. Finding The following measures have been incorporated into the project which, if properly implemented, would avoid or substantially lessen the possible erosion effects to a level of insignificance. Straw or other suitable materials will be placed over uncovered soils, as needed, during street construction activities. This would reduce the amount of erosion. 086 Oo Temporary culverts, ditches, catch basins, dams, and settling ponds will be installed in the street construction areas to maintain existing drainage flows and to collect excess water and sediments flowing out of the construction sites. Sediments collected will be disposed of at a Class II or Class III disposal site. If reconstruction of the Santiago Creek Bridge supports is determined to be necessary, construction activities will be limited to dry months. Bridge design and construction activities will be coordinated with the Orange County Environmental Management Agency, the California Department of Fish and Game, and the U.S. Army Corps of Engineers, and will comply with all of their requirements. Temporary drainage and erosion controls such as sandbags, ditches, dams, culverts, catch basins, and settling ponds will be used, as needed. Collected sediments will be properly disposed of at a Class II or Class III disposal facility. Rationale Covering of exposed ground surfaces will effectively minimize the amount of ground surface area which can be directly disturbed by strong winds. Installation of temporary culverts, ditches, catch basins, dams, and settling ponds within the construction zones, will provide ongoing drainage controls, should a rainstorm interrupt the construction process. The collection of run- off from the construction zones in culverts, catch basins, dams, and settling ponds will prevent this run-off from flowing onto the paved street and into the street drainage system, enabling proper disposal of the sediment in a suitable landfill facility, rather than contributing to potential downstream water pollution. By limiting construction of the bridge widening to typically dry months, the potential for erosion and increased sedimentation within the streambed is significantly diminished. With installation of the various temporary drainage and sediment collection controls, additional sedimentation due to bridge construction will be effectively minimized. Floodplain/Floodway Encroachment Significant Effects A small portion of the project area, in the vicinity of the Warner Avenue/Bristol Street intersection is within a floodplain, subject to potential overflow with a one-foot flooding depth from a 100-year flood event along the Santa Ana River. In addition, the Santiago Creek Channel has the potential for overtopping its banks and the existing Bristol Street Bridge, during a 100- year storm event. This channel has been identified as a floodway, by the Federal Emergency Management Agency. Construction of street and bridge improvements could affect flooding conditions in these areas. 08? Finding The following measure has been incorporated into the project which, if properly implemented, will avoid or substantially lessen potential effects on the floodplains and floodway within the project area, to a level of insignificance. Routine construction procedures will be implemented to minimize impacts to the floodplains. With regard to the bridge over Santiago Creek, the design will consider the possibility of the creek overtopping its banks and will be designed in accordance with Federal Emergency Management Agency requirements to withstand such an episode. Rationale The risks associated with the Santa Ana River floodplain at the southerly periphery of the project area and the Santiago Creek are minimal. The widening of the Santiago Creek Bridge would entail very minor encroachments into the creek, which will not affect the floodway as long as the existing bridge elevation is maintained. The proposed project would not be a longitudinal encroachment into either of the two floodplains and would not contribute to incompatible floodplain developmentl and would have no significant impacts on natural and beneficial floodplain values, including biological resources. P. Streambed Modification Significant Effects Construction of a widened bridge section within Santiago Creek, could result in the removal of several ornamental trees found along the roadway shoulders, adjacent to the bridge. No wetlands resources are found within the streambed. Some disturbance of non-significant streambed vegetation and wildlife may occur and vegetation/wildlife supporting water flow could be interrupted. Finding The following measures have be[n incorporated into the project which, if properly implemented, would avoid or substantially lessen streambed modification effects to a level of insignificance. Replacement of trees will occur on those roadway shoulders without surviving trees. 088 o Bridge widening design and construction will comply with applicable requirements of the U.S. Army Corps of Engineers Nationwide Permit provisions, pursuant to the Federal Clean Water Act, and with applicable requirements of the California Department of Fish and Game, pursuant to Section of the State Fis. h and Game Code. Rationale Replacement of trees that are removed during bridge construction will restore this lost vegetation which provides both wildlife habitat and scenic values. The U.S. Army Corps of Engineers Nationwide Permit essentially recognizes the extremely minor disturbance that will occur within the streambed and that no important streambed values, with respect to wetlands, water flow or water quality will result. Compliance with any California Department of Fish and Game permit requirements is expected to involve only routine construction procedures to control drainage and sedimentation, since no wetlands exist here, the creek is normally dry and this portion of Santiago Creek supports minimal vegetation and wildlife, none of which was found to be rare, endangered, or significant in any way, by the biologist who surveyed this area during preparation of the Environmental Impact Report. 1.0 2.0 EXHIBIT "B" MITIGATION MONITORING AND REPORTING PROGRAM FOR THE BRISTOL STREET WIDENING PROJECT INTRODUCTION On January 1, 1989, California State Assembly Bill (AB) 3180 became effective. AB 3180 requires state and local agencies to adopt programs for the monitoring and reporting of the implementation of mitigation measures addressing the significant environmental impacts of projects the agencies approve subject to the California Environmental Quality Act (CEQA). Consistent with AB 3180, the following Mitigation Monitoring and Reporting Program has been adopted for use by the City of Santa Ana as it carries out the Bristol Street Widening project. DEVELOPMENT OF THE MITIGATION MONITORING/REPORTING PROGRAM The basis of the Mitigation Monitoring/Reporting Program is the mitigation measures identified by impact category in Chapter IV of the Final Environmental Impact Statement and Final Environmental Impact Report (FEIS/FEIR). The development of the program is based on the following procedures: Identification of the specific mitigation measures proposed for the project from Chapter IV of this FEIS/FEIR. Identification of the key dates and events in the project implementation schedule. Identification of the key personnel and agencies responsible for environmental monitoring. Monitoring of the implementation of the mitigation measures and documentatkm that the measures have been properly and thoroughly implemented. Development of written documentation on the implementation of all the mitigation measures, identification of any areas of noncompliance, and proposed activities to bring the project into compliance with the mitigation monitoring program. 090 3.0 4.0 AUTHORITY TO REQUIR t:, AND ENFORCE AB 3180 The City of Santa Aha is required to enforce the provisions of AB 3180, consistent with its existing Police powers. As lead agency for the environmental documentation for the proposed 15roject and the agency with the authority to approve the proposed project, the City is also the agency responsible for approving the Mitigation Monitoring/Reporting Program and for accepting the written report(s) documenting the completion of the implementation of the mitigation measures. The Public Works Agency of the City will be responsible for coordinating the Mitigation Monitoring Program with the appropriate City departments and outside contractors and consultants. PROPOSED MmGATION MONITORING PROGRAM Table 1 summarizes the mitigation measures for Chapter IV, the appropriate schedule for implementation of each measure and the City department or other parties responsible for implementing each measure and documenting that each measure has been correctly implemented. The proposed procedures for implementing the Mitigation Monitoring and Reporting Program are: 4.1 Monitoring Procedures An Environmental Monitor will be responsible for reviewing the project plans, demolition plans and activities, right-of-way acquisition, residential and business relocation, construction sites, and/or operations to ensure that the mitigation measures are properly and completely accomplished during the implementation of the project. Written documentation that each mitigation measure in Table 1 is implemented. This documentation can be on a City of Santa Ana mitigation monitoring checklist or any similar form that clearly indicates the schedule for implementation, whether the measure has been implemented, or in the case of measures that are ongoing, that a process has been developed to ensure continued implementation of the measure. For example, the mitigation measures related to the construction period traffic controls are short-term and would be implemented and in place until the completion of each phase of the project. On the other hand, the redevelopment of remnant parcels not used for roadway purposes would be ongoing and would require a commitment on the part of the City to facilitate productive reuse of the land through the exercise of its redevelopment 091 4.2 power, e.g., to assemble small parcels into larger development sites, install landscaping, parking facilities, pedestrian amenities, etc. ReporfingProcedures ho The Environmental Coordinator will be responsible for reviewing the program in Table 1 with the key personnel charged with implementing the proposed project at the City, including the Director of Public Works, the City Traffic Engineer, the design consultants, construction contractors, construction inspectors, and all other key staff and contractors associated with the project. The Environmental Coordinator will prepare quarterly written reports for the City of Santa Ana Public Works Agency, documenting the satisfactory implementation of all applicable mitigation measures, during that time period, consistent with the schedule and agency approvals indicated in Table 1. For those measures where the project activities do not comply with Table 1, a description of the areas of noncompliance will be prepared, including proposed remedies to bring those elements of the project into compliance with the adopted Mitigation Monitoring/Reporting Program. The final report on the Mitigation Monitoring and Reporting Program will be provided to the City of Santa Ana Public Works Agency and will be kept on file at their offices located at 101 West 4th Street, in the City of Santa Ana.
