INTRODUCTION In accordance with your request, Ninyo & Moore has performed a water quality evaluation of the project site located in Carlsbad, California (Figure 1). The purpose of this study was to evaluate hazardous materials conditions using available data and to provide a report, which will be utilized in the preparation of environmental impact documents. This report presents our findings and con- clusions pertaining to the proposed El Camino Real Road Widening Project (Project). Subsurface exploration and laboratory testing of materials were not included in the scope of this evaluation. 2. SCOPE OF SERVICES RECON retained Ninyo & Moore to conduct a water quality evaluation for inclusion into an envi- ronmental impact report (EIR). The services were conducted in general accordance with Ninyo & Moore's proposal and scope of services dated January 13, 1998, and the subcontractor agreement between Ninyo & Moore and RECON. Ninyo & Moore's scope of services included the following tasks: • Reviewing readily available maps, reports, photographs, plans and other documents pertinent to water quality issues for the site. The City of Carlsbad and RECON was requested to pro- vide copies of, or access to pertinent maps, reports, photographs, plans and other documents in their possession. • Performing a site reconnaissance to visually identify areas of existing or potential water quality issues. • Reviewing readily available local regulatory agency information regarding surface water and groundwater for the site. Requests for information were made to the Department of Water Resources, County Department of Environmental Health, Regional Water Quality Control Board, State Water Quality Information System, and the United States Geological Survey. • Preparing this Water Quality Evaluation report including an introduction, methodology, exist- ing conditions, impact analysis, criteria of significance and mitigation measures supported by illustrations, references, agencies and individuals contacted, and a list of preparers. 363MI3R-r.DOC .'& I I I I I I E I I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 3. SITE BESRIPTION AND EXISTING CONDITIONS The project area consists of an approximately 1,200-foot long section of El Camino Real (station 441+00 to 453+00), approximately 2V£ miles northwest of Palomar Airport Road in the city of Carlsbad (see Figure 1). El Camino Real is currently a four-lane roadway, with a paved section that is approximately 100-feet wide. In the project area, the roadway is located on a fill embank- ment that ranges from seven to ten feet in height above the surrounding floodplain of Agua Hedionda Creek. From Station 441+70 to Station 442+83, El Camino Real crosses Agua He- dionda Creek via a concrete bridge. The bridge is 113-feet long and 108 feet wide and is supported at two bents within the creek channel and two abutments. According to a report dated January 15, 1997, prepared by Agra Earth and Environmental, Inc., (AGRA) the foundation of the bridge consists of 14 Class XI piles at each abutment and bent. The AGRA report indicates that the piles may be either precast, prestressed concrete piles or step-taper steel shells (Raymond Step-Taper Piles) filled with concrete. The exposed portions of the piles at the bents are 16-inch diameter concrete columns. Elevations across the project area range from approximately 45.8 feet above mean sea level (MSL) near the center of the bridge to roughly 29 feet MSL within the Agua Hedionda Creek channel, west of the bridge. A topographic map is provided as Figure 2. Vegetation consists of moderate to dense native growth along the sides of the creek channel and within the floodplain west of the road. Agricultural land exists on the north side of El Camino Real, northwest of the bridge. A trailer park development exists on the north side of El Camino Real, northeast of the bridge. 4. PROJECT DESCRIPTION The proposed project will consist of the widening of El Camino Real from approximately Station 441+00 to Station 453+00 (roughly 1,200 feet). The widening includes the addition of one lane on each side, widening the existing bridge over Aqua Hedionda Creek by two feet on each side, and the addition of a right-turn lane from southbound El Camino Real to (future) westbound Can- 3635-03R-r.DOC tylnyo I I I I E E E I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 non Road. The proposed Cannon Road will cross El Camino Real approximately 75 feet north of the existing bridge, then will cross Aqua Hedionda Creek via a proposed bridge to be located ap- proximately 150 feet southwest of the existing El Camino Real bridge. 5. ENVIRONMENTAL SETTING The following sections include discussions of the topographic, geologic, soil and hydrogeologic conditions; a review of available published documents; and presents the findings of our visual site reconnaissance of the property and adjacent areas. 5.1. Topographic Conditions In general, the project is located in near the center of Agua Hedionda Valley, and the area surrounding the project consists of moderate to steeply ascending hills. Surface drainage in the valley is towards the southwest into the nearby Agua Hedionda Lagoon. The approximate elevation of the current road is 40 to 45 feet MSL. A topographic map is presented as Figure 2. 5.2. Geologic Conditions The project area is situated in the western portion of the Peninsular Ranges geomorphic province of southern California. This geomorphic province encompasses an area that extends 125 miles, from the Transverse Ranges and the Los Angeles Basin, south to the Mexican border, and beyond another 775 miles to the tip of Baja California (Norris and Webb, 1990). The geomorphic province varies in width from 30 to 100 miles, most of which is character- ized by northwest trending mountain ranges separated by subparallel fault zones. In general, the Peninsular Ranges are underlain by Jurassic-age metavolcanic and metasedimentary rocks and by Cretaceous-age igneous rocks of the southern California batholith. The westernmost portion of the province in San Diego County, in which the site is located, generally consists of Upper Cretaceous-, Tertiary-, and Quaternary-age sedimentary rocks. 3635-03R-r.DOC i iii E [ C E I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 The Peninsular Ranges are traversed by several major active faults (Figure 3, Fault Location Map). The Whittier-Elsmore, San Jacinto, and the San Andreas faults are major active fault systems located northeast of the site and the Agua Blanca-Coronado Bank and San Clemente faults are active faults located to the west-southwest. The Rose Canyon fault zone is also a major fault system, located offshore of Carlsbad, portions of which have recently been recog- nized as active by the State of California. Major tectonic activity associated with these and other faults within this regional tectonic framework is right-lateral strike-slip movement. These faults, as well as other faults in the region, have the potential for generating strong ground motions at the project site. 5.3. Site Geology Based on our literature review, including published geologic maps and available geotechnical reports, the project is underlain generally by artificial fill, alluvium, and formational materials of the Santiago Formation. A brief description of these units, as described in the cited litera- ture, or as observed at the project area, is presented below. 5.3.1. Artificial Fill Previous construction along and adjacent to El Camino Real has resulted in the place- ment of artificial fill. Based on review of previous geotechnical reports and topographic maps, these fill soils are expected to be up to roughly 10 feet deep along the existing roadway. These soils consist generally of clayey sands and silty sands. In addition to these soils, riprap composed of boulder-sized rocks locally line the abutments of the ex- isting bridge. 5.3.2. Alluvium Recent alluvial deposits underlie the fill soils. The alluvium was within the floodplain of Agua Hedionda Creek. Based on the previous geotechnical reports, the alluvium is de- 3635-03R-T.DOC I I I I I I P I! i RECON June 4, 1998 El Camino Reai Road Widening Project, Carlsbad (Revised) Project No. 103635-03 scribed as soft to stiff silty clay and loose to medium dense silty sand. The alluvium is expected to be greater than 100-feet deep in the project vicinity. 5.3.3. Santiago Formation Materials of the Eocene-age Santiago Formation underlie the alluvium in the project area. The Santiago Formation is described as very dense, silty sandstone and interbedded hard claystone. A more detailed analysis of geologic conditions, including faults, liquefaction, landslides, and other geologic hazards are discussed under a separate report prepared by Ninyo & Moore dated June 4, 1998. 6. HYDROLOGIC SETTING This section summarizes the regional hydrologic setting and project hydrologic conditions. The information is based on our review of the referenced reports, including observations made by Ninyo & Moore in the project area. 6.1. Hydrologic Unit According to available hydrogeologic data from the Regional Water Quality Control Board (RWQCB) and the California Department of Water Resources (DWR), the project is located in the Los Manos Hydrologic Subarea within the Agua Hedionda Hydrologic Area, which is within the Carlsbad Hydrologic Unit. The Carlsbad Hydrologic Unit is a triangular shaped area of approximately 210 square miles, extending from Lake Wohlford on the east and the Pacific Ocean on the west, and from Vista on the North to Cardiff-by-the-Sea on the south. The area is drained by Buena Vista, Agua Hedionda, San Marcos, and Escondido Creeks. Annual precipitation varies from less than 11 363M0R.-r.DOC I I I I I I E E I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 inches near the coast to 20 inches near Lake Wohlford. It is bordered to the north, by the watershed of San Luis Rey River and on the south, in part by that of the San Dieguito River. The Agua Hedionda Lagoon is located approximately one mile southwest of the project. The lagoon is routinely dredged to keep it open to the ocean. The lagoon serves as a integral part of a electrical power plant cooling water intake system and also provides a reserve cooling water supply. The eastern portion of the lagoon is used for water recreation. 6.2. Groundwater Based on our site reconnaissance and review of previous reports, the depth to groundwater is expected to occur at a depth of approximately 10 to 15 feet below the existing road grade. The depth to groundwater may be at or near the ground surface within Aqua Hedionda Creek. The depth to groundwater at the site may fluctuate with seasonal variations and perched conditions may be locally present. 6.3. Surface Water The Agua Hedionda Creek channel crosses the project. At the time of our site reconnaissance on My 15, 1998, there was a moderate flow of water within Aqua Hedionda Creek. The creek drains to the southwest and empties into the nearby Agua Hedionda Lagoon. 7. STATUTORY/REGULATORY BACKGROUND The Regional Water Quality Control Board - San Diego Region (RWQCB), has developed poli- cies, rules, and procedures, and has been granted the authority to implement and enforce the laws and regulations requiring the control of water quality. The principal federal and state laws per- taining to the regulation of water quality are known respectively as, the 1972 Federal Water Pollution Control Act (also known as the Clean Water Act) and Division 7 of the 1969 California Water Code (also known as the Porter-Cologne Water Quality Control Act). The laws are similar in many ways. The fundamental purpose of both laws is to establish beneficial uses and to provide 363S-03R-r.DOC tyinyo I I I I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 for their protection. An important distinction between the two is that the Porter-Cologne Water Quality Control Act addresses both ground and surface waters while the Clean Water Act ad- dresses surface water only. The water quality objectives used for this study are primarily contained within the Water Quality Control Plan (Basin Plan), San Diego Basin (9) (RWQCB September 1994). The Basin Plan defines existing and potential beneficial uses and water quality objectives for coastal waters, groundwaters, surface waters, imported surface waters, and reclaimed waters in the basin. The Basin Plan also summarizes drinking water standards as specified by the California Department of Health Services, the California Inland Surface Waters Plan (State Water Resources Control Board 1991), and Code of Federal Regulations Title 40 Part 131. The Clean Water Act (CWA) also established the National Pollutant Discharge Elimination System (NPDES), which requires permits for discharges of pollutants from certain point sources into waters of the United States. Point sources are defined as "...any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharged. Point source wastes can be generated by residential, commercial, industrial, agricultural, certain recreational and solid waste disposal activities and/or practices" (RWQCB, 1994). In contrast, nonpoint source pollution is generally defined as "...sources which are diffuse in nature, usually associated with man's uses of land..." (RWQCB, 1994) and are exempt from NPDES permitting requirements. This has led to some confusion regarding regulation of point and nonpoint sources (e.g., NPDES was designed to regulate stormwater and urban runoff, which are nonpoint sources that become point sources). In 1990, the United States Congress amended the Coastal Zone Management Act by adding the Coastal Zone Act Reauthorization Amendments (CZARA). Section 6217 of CZARA established the Coastal Nonpoint Pollution Control Program, which requires the United States Environmental 363Wt3R-T.DOC e i i i i i E E I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 Protection Agency (US EPA) to develop and states to implement best management practices (BMPs) to control nonpoint source pollution in coastal water. The definition of coastal waters in California was expanded to include the entire state. Pursuant to Section 6217(g) of CZARA, six major categories of nonpoint sources addressed by CZARA include agriculture, forestry, urban areas, marinas, hydromodification projects and wetlands. Although the two programs (NPDES and CZARA) are complementary and exclusive of each other, their implementation has led to some confusion. In summary, the NPDES permitting program essentially regulates stormwater and urban runoff, while virtually all other nonpoint sources are subject to the Coastal Nonpoint Pollution Control Program under CZARA. The CWA allows the United States Environmental Protection Agency (EPA) to delegate NPDES permitting authority to states with approved environmental regulatory programs. California is one of the delegated states. In 1987, the federal Water Quality Act (WQA) added Section 402(p) to the CWA. Pursuant to Section 402(p)(4), EPA promulgated regulations for NPDES permit applications for stormwater discharges. These federal regulations became effective on October 31, 1990. In anticipation of this final ruling, RWQCB issued Order No. 90-42, NPDES No. CA 0108758, "Waste Discharge Requirements for Stormwater and Urban Run-off from the County of San Diego, the Incorporated Cities of San Diego County and the San Diego Unified Port District," on July 16, 1990. Order No. 90-42 presents guideline requirements for the control of pollutants resulting from stormwater and urban runoff from all areas named in NPDES Permit No. CA 0108758. RWQCB Order 90-42 specifically requires co-permittees to; "Inventory existing stormwater pollution control programs, illicit discharge detection programs, monitoring programs and data, stormwater conveyance system maps, land use maps, and existing laws, ordinances, and codes giving the dischargers the authority to implement and enforce storm- water pollution control programs in their areas of jurisdiction and where necessary, promulgate the authority to carry out all functions of the stormwater management programs." 3635-03R-r.DOC ty/nyo E [ C I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 Specific conditions of the NPDES permit that may directly affect the planning and design re- quirements of the proposed project are: • Development and implementation of stormwater and receiving water monitoring programs to evaluate discharges of pollutants from stormwater conveyance systems to waters of the United States. • To the maximum extent practicable, development and implementation of best management practices to control discharges of pollutants to waters of the United States. According to the Code of Federal Regulations Title 40, Section 122.2 (40 CFR 122.2), BMPs mean schedules of activities, prohibitions of practices, maintenance procedures, and other man- agement practices to prevent or reduce the pollution of waters of the United States. BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage. In response to NPDES regulations, the California State Water Resources Control Board (SWRCB) has issued the General Construction Activity Stormwater Permit (Permit), which was adopted by SWRCB on August 20, 1992. In order to be in compliance with the Permit, all projects involving 5 acres or more of soil disturbance will require NPDES permits which must include the following: • Notices of Intent (NOIs) - Certification to be signed by owner of the construction site. • Stormwater Pollution Prevention Plans (SWPPPs). • Monitoring Programs - Including inspection of prevention measures, record keeping and an- nual certification of compliance, due July 1, 1993, and each July 1st thereafter. • Post Construction Stormwater Management - Describing operation and maintenance of con- trol practices including identification of funding. The San Diego RWQCB, which receives its notification of NPDES permit issuance directly from SWRCB, has the power of enforcement and inspection over NPDES permits and may require ad- 3635-03R-r-DOC I I I I I I I I RECON June 4, 1998 El Carnino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 ditional reports and information. However, they typically will not receive or review copies of SWPPPs. It is important to recognize that NPDES permits are issued separate from normal per- mits required by local public works agencies and should not be submitted to these agencies for additional approval. It is likely that these agencies will require copies of NPDES permit numbers prior to approving any local grading or land development permits, similar to their requiring evi- dence of Federal 404 or 1602 compliance. 8. BENEFICIAL WATER USES Beneficial uses of groundwater and surface water have been established for each water body within the San Diego County region. According to the Basin Plan, beneficial uses are defined as the uses of water necessary for the survival or well being of man, plants and wildlife. These uses of water serve to promote the tangible and intangible economic, social and environmental goals of mankind. Examples include drinking, swimming, industrial and agricultural water supply, and the support of fresh and saline aquatic habitats. According to the Basin Plan (RWQCB, 1994), beneficial uses have been designated for specific coastal water bodies, inland surface waters, and groundwaters. The waters potentially impacted by the project are the surface waters of Agua Hedionda Creek and groundwater of the Agua Hedionda Hydrologic Area. The beneficial use designations described below are categorized as "existing" or "potential" beneficial uses, according to the Basin Plan. In general, the designation of an existing beneficial use has been established by demonstrating that: 1) fishing, swimming, or other uses have actually occurred since November 28, 1975; or 2) the water quality and quantity are suitable to allow the use to be attained. Beneficial uses are designated as "potential" for a variety of reasons, including: 1) plans are proposed to put the water to a future use; 2) the potential exists to put the water to a future use; 3) the public desires to put the water to future use; 4) the water is potentially suitable for 363MBR-r.DOC 10 tylnyo E E I I I I RECON June 4, 1998 El Carnino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 municipal or domestic water supply under the terms of the "Sources of Drinking Water Policy" (State Board Resolution No. 88-63); or 5) the RWQCB has designated a beneficial use as a regional water quality goal. Designated beneficial uses are generally, but not always, present throughout the entire reach of a particular hydrologic unit, area, subarea, or water body. Designated beneficial uses may not be present throughout the year. Specific beneficial uses near or below discharges will be carefully evaluated by the RWQCB during the development of waste discharge requirements or enforcement orders. The lack of a beneficial use listed for any given area does not rule out the possibility of existing or future beneficial uses. The California Water Code establishes a comprehensive program for the protection of beneficial uses of the waters of the state. Water Code Section 13050(f) describes the beneficial uses of surface and groundwaters that may be designated by the State or RWQCBs for protection as, but are not necessarily limited to, domestic, municipal, agricultural and industrial supply; power generation; recreation; aesthetic enjoyment; navigation; and preservation and enhancement offish, wildlife, and other aquatic resources or preserves. Currently designated existing beneficial uses of the surface water of the Agua Hedionda Creek are: • Municipal and Domestic Supply (MUN) includes uses of water for community, military , or individual water supply systems including, but not limited to, drinking water supply. • Agricultural Supply (AGR) includes uses of water for farming, horticulture, or ranching in- cluding, but not limited to , irrigation, stock watering, or support of vegetation for range grazing. • Industrial Service Supply (IND) includes uses of water for industrial activities that do not de- pend primarily on water quality including, but not limited to, mining, cooling water supply, hydraulic conveyance, gravel washing, fire protection, or oil well repressurization. • Contact Water Recreation (REC-1) includes uses of water for recreational activities involving body contact with water, where ingestion of water is reasonably possible. These uses include, but are not limited to, swimming, wading, water skiing, skin and scuba diving, surfing, white water activities, fishing, or use of natural hot springs. 3633-03R-r.DOC 11 I 1 I I c c I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 • Non-Contact Water Recreation (REC-2) includes the uses of water for recreational activities involving proximity to water, but not normally involving body contact with water so that in- gestion of water is not reasonably possible. These uses include, but are not limited to, picnicking, sunbathing, hiking, beachcombing, camping, boating, tidepool and marine-life study, hunting, sightseeing, or aesthetic enjoyment in conjunction with the above activities. • Warm Freshwater Habitat (WARM) includes uses of water that support warm water ecosys- tems including, but not limited to, preservation or enhancement of aquatic habitats, vegetation, fish or wildlife, including invertebrates. • Wildlife Habitat (WILD) includes uses of water that support terrestrial ecosytems including but not limited to, preservation of and enhancement of terrestrial habitats, vegetation, wildlife, or wildlife water and food sources. Currently, there are no potential beneficial uses designated for the surface waters of Agua Hedionda Creek. Currently designated existing beneficial uses for the groundwater of the Los Monos Hydrologic Subarea are: • Municipal and Domestic Supply (MUN) includes uses of water for community, military , or individual water supply systems including, but not limited to, drinking water supply. • Agricultural Supply (AGR) includes uses of water for farming, horticulture, or ranching in- cluding, but not limited to, irrigation, stock watering, or support of vegetation for range grazing. • Industrial Service Supply (IND) includes uses of water for industrial activities that do not de- pend primarily on water quality including, but not limited to, mining, cooling water supply, hydraulic conveyance, gravel washing, fire protection, or oil well repressurization. Currently, there are no potential beneficial uses designated for the groundwater of the Los Monos Hydrologic Subarea. 8.1. Water Quality Objectives The Porter-Cologne Water Quality Control Act (California Water Code, Division 7, Chapter 2) requires that beneficial uses and water quality objectives be established for both surface 3635-03R-r.DOC 19 I I E I I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 and groundwaters of the state. The establishment of beneficial uses and water quality objec- tives (or criteria) for surface water is also mandated by the federal Clean Water Act (33 U.S.C.). The California Water Code defines water quality objectives as: The limits or levels of water quality constituents or characteristics which are established for the reasonable protection of beneficial uses of water or the prevention of nuisance within a specific area. In establishing water quality objectives, the Regional Board must provide for the reasonable protection of all beneficial uses which are designated for protection, taking into account ex- isting water quality, environmental and economic considerations. California Water Code Section 13241 provides that the Regional Board shall consider, but is not limited to, the fol- lowing factors in establishing water quality objectives: • Past, present and probable future beneficial uses of water; • Environmental characteristics of the hydrographic unit under consideration, including the quality of water available thereto; • Water quality conditions that could reasonably be achieved through the coordinated control of all factors which affect water quality in the area; • Economic considerations; • The need for developing housing within the region; and • The need to develop and use recycled water. The Basin Plan states that: • Water Quality objectives for waters of the state must conform to the State Board Resolu- tion No. 68-16, "Statement of Policy with Respect to Maintaining High Quality of Waters in California." Under State Board 68-16, which applies to all waters of the State, the Re- gional Board and State Board must have sufficient grounds to adopt findings which demonstrate that any water quality degradation will: o Be consistent with the maximum benefit to the people of the State; 3635-03R-r.DOC 13 ty/nyo I I I I I c E E C I I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 o Not unreasonably affect existing and potential beneficial uses of such water; and o Not result in water quality less than described in the Basin Plan. Resolution No. 68-16 establishes a general principle of nondegradation with flexibility to allow some changes in water quality which is in the best interests of the State. Changes in water quality are allowed only where it is in the public interest and beneficial uses are not unreasonable affected. The Federal Clean Water Act (Section 303(c)(2)(B)) established numeric criteria for a limited number of priority toxic pollutants for inland surface waters in California, How- ever, California is not currently in full compliance with the Clean Water Act due to the invalidation of the Water Quality Control Plan for Inland Surface Waters of California, and the Water Quality Control Plan for Enclosed Bays and Estuaries of California. Ac- cording to the Basin Plan, these criteria established by the federal Clean Water Act are still applicable to the surface waters in this region.M • The Basin Plan's water quality objectives are numerical or narrative limits on constituents or characteristics of water designed to protect designated beneficial uses of the water. Water quality objectives are primarily achieved through the establishment of waste dis- charge requirements and implementation of the Basin Plan. Numerical limits represent the maximum level of constituents that will allow for the beneficial use to continue unim- paired. An objective may allow for natural, or "background" levels of a constituent or characteristic, but prohibit any increase above these levels, or may simply express an ob- jective in terms of not adversely impacting beneficial uses (i.e., narrative limit). Water quality objectives applying to all inland surface waters and coastal waters of San Diego Bay are specified in Chapter 3 of the Basin Plan. Specific numerical water quality objectives are presented by hydrologic area, subarea and watershed in Tables 3.1 and 3.2, Chapter 3 of the Basin Plan. 9. STORMWATER RUNOFF A growing concern of regulatory agencies and the public is that surface runoff from roadways and urbanized areas has the potential to transport harmful pollutants, either as dissolved or paniculate matter, to nearby sensitive receptors such as wetlands, surface water and groundwater. Pollutants are generally classified as heavy metals (e.g., lead, copper, cadmium, iron, zinc, chromium, manganese, nickel), oil and grease, nutrients (nitrate, nitrogen, phosphorus, phosphate) and residue (particulates). These pollutants are derived from a number of sources such as vehicles, unauthorized releases related to accidents, winds and fallout of air pollutants. The adverse impact 3635-03R-r.DOC 14 I I I I c E E I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 of these pollutants on sensitive receptors would be related to their toxicity, oxygen consuming, biostimulation and aesthetic characteristics. The magnitude of the impact would be a function of these characteristics as well as pollutant concentration and/or total pollutant load reaching the receptor(s) from a single storm event (acute impact) or over a period of years (chronic impact). In a study conducted by Kerri, et al. (1985), forecasting regression equations were developed for estimating pollutant loads in runoff from urban highways. Data for their study were collected from California highway sites which included Redondo Beach (1-405), Walnut Creek (1-680), Sacramento (U.S. 50) and Placerville (U.S. 50). They recommended that proposed highway projects having: 1) anticipated traffic volumes of at least 30,000 average daily traffic (ADT), and 2) nearby sensitive environmental receptors, should determine constituent loads for chemical oxygen demand, filterable residue, total lead, total Kjeldahl nitrogen and total zinc from highway surfaces. These data would then be used as an aid in evaluating the environmental impact of surface runoff. They also recommended that studies of surface runoff quality should include monitoring of vegetation and aquatic life so that mitigation measures can be modified to remain compatible with facility design. Their study did not address road slope (unpaved) runoff which may receive pollutants from adjacent land uses and regional, stationary sources via rainfall. Their study also identified total pollutant load as a more important variable than maximum concentration in assessing the impact of pollutants on sensitive receptors. Essentially, the concentration of pollutants at the receptor is much more significant than maximum pollutant concentrations at or near the roadway. Therefore, the processes affecting the pollutants during transport (e.g., dilution, volatilization, biodegradation, photo-oxidation) need to be identified so that planners and/or environmental specialists can calculate changes in pollutant concentrations resulting from development. The study made the following conclusions, which are applicable to the proposed urbanized areas of the project site: 3635-03R-r.DOC 15 I I E E E I I I I I I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 • Urban highways in California operating under normal conditions (i.e., no accidents or chemi- cal spills) do not produce large amounts of pollutant constituents during storm runoff events. I The findings of the research indicate that for highway segments which drain between 2 and 3 acres of completely paved areas, and had six to eight traveled lanes, the constituent loads in runoff water were sufficiently low so that costly treatment facilities are not needed to meet • water quality objectives.water quaty oectves. • The following constituents exhibited a 'first flush1 pattern with relatively insignificant loads and concentrations: sulfate, iron, chromium, copper, manganese, nickel, bicarbonate ion, carbon- ate ion, calcium, magnesium, chloride, mercury, molybdenum, potassium, silica, and sodium. • The number of dry days between storm events and the corresponding cumulative traffic vol- ume before the storm were found to be not statistically significant for quantifying cumulative constituent loads. • After the initial pavement and gutter loads are washed off, vehicles traveling on the highway will continue to release pollutant constituents. Pollutants will also be reaching the highway surface from atmospheric fallout and surrounding land-use activities. 10. BEST MANAGEMENT PRACTICES BMPs were originally developed to protect water quality by controlling erosion and sedimentation at the source. They since have been expanded to include controlling the volume and concentra- tion of chemical pollutants entering waters of the United States. BMPs include such standard practices as lengthening detention periods, covering bare areas with mulches, constructing infiltration facilities, and providing public education as to the consequences, both legally and environmentally, of illicit discharges to stormdrains. Two comprehensive documents addressing BMPs are the "Storm-Water Management Manual for the Puget Sound Basin," produced by the Washington State Department of Ecology (Technical Review Draft, 1990), and the State of California, "Stormwater Best Management Practice Hand- books" (Preliminary Draft, 1992). In general, BMPs have been divided into two broad categories: quality control (e.g., pollution control) and quantity control (e.g., controlling runoff volume and peak rate). 3635-03R-T.DOC 16 tyinyo I I c c G E E C E I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 Quality control BMPs are further subdivided into source control and treatment BMPs. As the name implies, source control BMPs are designed to prevent pollution of stormwater, while treat- ment BMPs are used to treat other types of runoff pollution. According to these documents, the most practical approach is to use source control BMPs as the primary system, and treatment BMPs as the secondary system. Treatment BMPs are more effective and efficient when used to handle pollutants that get past the source control BMPs. Quantity control BMPs are subdivided into volume control (e.g., infiltration and retention BMPs) and those directed toward peak rate control (e.g., detention facilities). To maximize efficiency and minimize costs, treatment and quantity control BMPs can be designed into a single facility. An example is the use of a wet pond, which treats storm-water by allowing solids to settle out and promoting biological assimilation of dissolved pollutants through the use of an extended retention period. Peak rate control is then obtained through the controlled release of water from the pond. In order to select, design and implement the most effective and efficient BMPs, certain parameters have to be established. Important items to consider include identification of target pollutants, physical and chemical characteristics of those pollutants, anticipated volumes and concentrations of pollutants and stormwater, and any regulatory action levels (e.g., drinking water standards, nondegradation policies). 11. WATER QUALITY The following sections discuss point and nonpoint sources of pollution that can or have adversely impacted water quality in the study area. 11.1. Nonpoint Sources Although stormwater runoff is part of the natural hydrologic cycle, human activities, particu- larly urbanization, can result in significant and problematic changes to the natural hydrology 3635-03R-r.DOC 17 i E E I I I I I E RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 of an area. Under conditions of minimal urbanization, water percolates through pervious surfaces, in which soil filtration and biological action can attenuate, degrade or remove pol- lutants. Urbanization converts pervious surfaces (e.g., vegetated and natural ground cover) to impervious surfaces (e.g., rooftops, paved roads and parking areas) decreasing the infiltra- tion capacity of the soil for both water and pollutants. The increased water accumulating in a drainage or surface body of water may have significant, yet short term impacts both during and after storm events. Potential impacts include property damage, disturbance of wildlife habitat and exposure of the public to toxic chemicals and biohazards (e.g., coliform bacteria). Impervious areas also impact (reduce) the effective recharge area of the aquifer. Diminished recharge capacity of the aquifer results in a lowering of the groundwater table. A lowering of the groundwater elevation may impact those dependent upon well water and may impact vegetation. When rain falls on and flows across roads, industrial and commercial sites and residential neighborhoods, it picks up a multitude of pollutants. These pollutants can dissolve in the runoff or be adsorbed onto soil particles and quickly transported by gravity flow through a network of concrete channels and underground pipes referred to as stormdrain conveyance systems. These systems ultimately discharge the polluted runoff, without treatment, into creeks, rivers, estuaries, bays and oceans. Urbanization results in a dramatic increase in the volume, velocity and pollutant load carried by stormwater runoff to receiving waters. Pollutants typically found in urban runoff include sediment, nutrients (e.g., fertilizers), oxy- gen-demanding substances (e.g., decaying vegetation), bacteria, viruses, heavy metals, synthetic organics (e.g., fuels, oils, solvents, lubricants), pesticides and other toxic sub- stances. These pollutants can severely degrade the beneficial uses of surface water and groundwater, and threaten the health of both humans and aquatic organisms. In addition to the pollutants contributed by stormwater or wet weather flows, dry weather runoff can also seriously degrade the quality of the receiving water. Dry weather flows, 3635-03R-r.DOC 18 tyfnyo E i c G I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 which can be substantial, consist of flows from illicit connections and illegal discharges to the stormwater conveyance system. Common examples of the latter are illegally disposed used motor oil and anti-freeze. The findings of recent studies (e.g., Nationwide Urban Runoff Program) found that the pol- lutants and their concentrations in urban runoff are similar to those found in sewage and industrial wastewater discharges. Locally, the closure of southern California beaches follow- ing major storm events due to high bacteriological levels in ocean waters is a common occurrence. 11.2. Point Sources Documented point sources of groundwater contamination in the vicinity of the project area were not found during the hazardous materials evaluation conducted by Ninyo & Moore pre- sented under a separate cover dated June 4, 1998. 11.3. Water Quality Data The groundwater that occurs in the coastal plain section of the Carlsbad Hydrologic Unit generally is sodium chloride in character and has a concentration of total dissolved solids that range from 500 to 5,000 parts per million. Ratings of groundwater for domestic use in the coastal plain section of this unit range from suitable to inferior due to a high total dissolved solid content along with high nitrates or sulfates in local areas. The ratings of groundwater for irrigation use in the coastal plain section of this unit are marginal to inferior because of a high electrical conductivity and high chloride. Ninyo & Moore requested available groundwater and surface water quality data from the following agencies: California Department of Water Resources, County of San Diego De- partment of Environmental Health, Regional Water Quality Control Board - San Diego 3635-03R-r.DOC tylnyo i RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 Region, State Water Quality Information System, and the United States Geological Survey. The responses from the regulatory agencies and available data are included in Appendix A. 12. SIGNIFICANCE OF IMPACTS DETERMINATION The City of Carlsbad Department of Planning does not have a criteria for significance determina- tion guideline. The following criteria for significance determination were obtained from the document entitled "City of San Diego Planning Department, Environmental Analysis Section, Significance Determination Guidelines, under the California Environmental Quality Act" dated January 1991 (revised January 1994). 12.1. Hydrology The criteria for determining significant impacts to hydrology include the following: » If the project would impose flood hazards on other properties. • If the project would result in increased runoff. • If the project would result in modification of existing drainage patterns. • If the project would result in extraction of water from an aquifer. 12.2. Water Quality The criteria for determining significant impacts to water quality include the following: • If the project would result in pollution or contamination. • If the project would result in erosion and subsequent sedimentation of water bodies. 13. ENVIRONMENTAL IMPACTS I Based on our understanding of the proposed project and the information presented in this report, the following statements are offered regarding potential significant environmental impacts to hy- • drology and water quality related to the proposed project. i i i F i i i 363S-03R-t.DOC 20 tyfnyo C p I • I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 13.1. Hydrology The proposed project, located in a partially developed residential and agricultural area, does not have the potential to impose flood hazards on other properties. The project will increase the ratio of pervious to impervious area and potentially increase the amount of surface water runoff However, this potential is mitigatable to a level below sig- nificance. The project will not modify the existing drainage pattern. It is our understanding that construction dewatering is not anticipated. If conducted, con- struction dewatering would withdraw water from the shallow aquifer or the creek. However, due to the temporary nature of the withdrawal of groundwater, it is not anticipated that con- struction dewatering, if conducted properly (see following dewatering discussion), would result in any significant short-term or long-term, irreversible adverse impacts to the aquifer or the creek. 13.2. Water Quality It is not anticipated that the use, generation, storage or disposal of hazardous or potentially hazardous materials will be associated with the proposed project. Therefore, it is not antici- pated that the proposed project would result in a significant short-term or long-term, irreversible, adverse impact to shallow groundwater or the Agua Hedionda Creek. It should be noted that an active 16-inch diameter refined petroleum product pipeline is located in the project. It is anticipated that hazardous, or potentially hazardous materials will temporarily be used and stored at the site during construction phase of the project. Temporary use and storage of hazardous materials at the site have the potential to impact shallow groundwater and Agua E 3635-03R-r.DOC 21 I c c £ I I I I I I I C RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 Hedionda Creek. However, the potential to impact the surface waters and shallow ground- water is mitigatable to a level below significance. Proposed grading activities at the project site may temporarily increase the potential for ero- sion and discharging of sediment into the Agua Hedionda Creek during construction. However, the potential to impact the surface waters of Agua Hedionda Creek is mitigatable to a level below significance. 14. MITIGATION MEASURES The following sections discuss possible mitigation measures regarding the significant mitigatable impacts presented in Section 13 of this report. 14.1. Hydrology The project will not impose flood hazards on other properties, therefore, mitigation measures are not required. The potential for the increase in surface water runoff" can be mitigated to a less than signifi- cant impact by proper engineering and design of surface drainage. The project will not modify the existing stream drainage pattern, therefore, mitigation meas- ures are not required. Construction dewatering is not anticipated for the project. If temporary construction dewa- tering occurs at the site, and the effluent is discharged to the surface waters, then the discharge shall meet the effluent limits specified by the RWQCB (Order No. 96-41 / NPDES CAG919002). If the effluent is discharged to the City of Carlsbad sewer system, then the effluent shall meet the discharge requirements of the City. Depending on water quality and existing environ- mental concerns (e.g., nearby groundwater contamination that may be influenced by 3635-03R-r.DOC 22 Ninuoty/ny i E C E I I I 1 I RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad (Revised) Project No. 103635-03 dewatering activities), the effluent may require treatment (e.g., oil/water separation, desilta- tion, activated carbon treatment) prior to discharge to the surface waters or sewer system to meet either NPDES of City discharge requirements. Discharge of the dewatering effluent to the sewer system reduces the potential impact to adjacent receiving waters; however, the City may not consider this a preferred alternative because it is not an efficient use of the sewer system. It is not anticipated that project-related temporary construction dewatering will have a significant, irreversible, short-term or long-term adverse impact on water quality provided that either NPDES or the City's requirements regarding construction dewatering are followed during the planning, construction and maintenance phases of the project. 14.2. Water Quality Hazardous or potentially hazardous materials (e.g., cement, lubricants, solvents, fuels, other refined petroleum hydrocarbon products, wash water) that are used or generated during the construction of the project should be handled, stored, used and disposed of in accordance with NPDES permitting requirements and applicable federal, state, and local laws and regu- lations. BMPs include preparation and implementation of a hazardous substance spill prevention/contingency plan (including material safety data sheets); providing adequate worker training and education; minimizing the volume of hazardous or potentially hazardous materials stored at the project at any one time; provide secured storage areas for compatible materials, with adequate spill containment; label containers; and keep records, manifests and other tracking information up to date. It is not anticipated that project-related hazardous or potentially hazardous materials will have a significant, irreversible, short-term or long-term adverse impact on water quality pro- vided that Caltrans Standard Specifications, NPDES permit, City of Carlsbad grading ordinances and other relevant construction practices and codes are followed during the plan- ning, construction and maintenance phases of the project.

Note that construction activity resulting in soil distur- bances of less than 5 acres also requires a permit if the construction activity is part of a larger common plan of development or sale. Construction activities are covered by Order Number 92-08-DWQ General Permit Number CAS 000002. Regulations set forth in the NPDES per- mit are enforceable by the RWQCB and local municipality. General permit conditions address notifications, prohibitions, effluent limitations, preparation and implementation of a storm- water pollution prevention plan (SWPPP), and monitoring program and record keeping requirements. The SWPPP addresses such topics as schedule; source identification; erosion and sediment control; non-stormwater management; post-construction stormwater manage- ment; waste management and disposal; maintenance, inspection and repair; and training. It is not anticipated that project-related erosion and sedimentation will have a significant, irre- versible, short-term or long-term adverse impact on water quality provided that Caltrans Standard Specifications, NPDES permit, City of Carlsbad grading ordinances and other rele- vant construction practices and codes are followed during the planning, construction and maintenance phases of the project. 15.
