FINANCIAL IMPACT: The estimated project cost is$196,000, funded by State Matching Funds (51.0%) and Road funds (49.0%). Ill. REASONS FOR RECOMMENDATION/BACKGROUND: The project will realign the existing sharp curve to provide a longer radius curve. The project includes roadway excavation, asphalt concrete pavement and acquisition of right-of-way. It is needed to increase posted speed from 20 mph to 35 mph which is consistent with this portion of Neroly Road. The project has been determined to be in compliance with the General Plan. A Negative Declaration of environmental significance pertaining to this project was published on November 18, 1994 with no protest, and the Board has considered the negative declaration together with all comments received during the public review period. This project has been found to be de minimis in its effect on the environment and is exempt from the $1,250.00 Fish and Game filing fee. V. CONSEQUENCES OF NEGATIVE ACTION: Delay in approving the project will result in a delay of design and construction and may jeopardize funding. Harvey E.

'��► November 18, 1994 rrq-cov::r NOTICE OF INTENT TO ADOPT A NEGATIVE DECLARATION NEROLY ROAD "S" CURVE REALIGNMENT, County File#CP 94-65: The project is located on Neroly Road, approximately 50 ft. north of the Contra Costa Canal, extending northward approximately 805 ft., in the Oakley area of east Contra Costa County (see Figures 1 - 3). The project site, as well as, the surrounding area, is agricultural, with a few rural residential homes. A parcel on the east side of Neroly Road, in the project area, has an approved subdivision plan, however, it has not yet been built. The Southern Pacific Railroad tracks (SPRR) are west of Neroly Road. Subject project is described as follows: The proposed project includes the realignment of approximately 805 feet of Neroly Road, acquisition of right-of-way (approximately 27,000 sq. ft. from 3 parcels), removal of some orchard trees, and the relocation of roadside drainage ditches (see Figure 3). The present configuration of the roadway does not meet existing design standards. The realignment of the existing "S" curve on Neroly Road to meet current design standards will provide a longer radius, allowing a higher posted speed which is compatible with the posted speed north and south of the "S" curve. In addition, Items #5 - 8 of the Environmental Evaluation are also included. As the owner of abutting property, or as an otherwise interested person or organization, you are invited to submit any comments you may have on this project, and raise any significant environmental issues of which you are aware so that they can be considered in the environmental review process.

The is based on the following summary of the Environmental Evaluation: 1. The project will not create unstable earth conditions, changes in geologic substructures or increase the exposure of people or property to geologic or water related hazards. 2 There are no rare or endangered species of plants or animals in the project area. The project will not increase the rate of use of natural resources. 3. The proposed project is consistent with Roadway and Transit Policies and Implementation Measures outlined in the County General Plan. 4. The project will not degrade the quality of the environment Construction activities will create minor,short-term,temporary impacts. But no significant impacts will occur since the following best management practices are incorporated into the project and in project specifications: 5. There will be no significant change in air quality in the project area. Construction machinery and vehicles will emit exhaust fumes and possibly objectionable odors during construction which may temporarily deteriorate local air quality. To minimize the impact, contract specifications-shafl-- stipulate the use of properly tuned and muffled equipment. Air quality impacts will also be reduced by eliminating unnecessary idling of machines when not in use. Adherence to standard dust control practices shall be required in order to reduce air quality impacts and potential for erosion during construction. 6. Best management practices mentioned in#5,and limiting work hours to 7:30 a.m.-5:00 p.m., Monday through Friday, unless modified upon written approval,will reduce construction noise levels and shall be incorporated as part of the construction contract. 7. During construction,traffic will be either diverted within the proposed right-of-way or detoured around the project site. This will create a temporary inconvenience,which will be minimized by installing sufficient signs warning of construction. In addition,no work which could interfere with commute traffic shall be performed before 8:30 a.m., nor after 4:30 p.m., when traffic is to be diverted within the Neroly Road right-of-way. 8. Standard construction safety practices shall be followed during construction to ensure no accidental release of hazardous substances or increase the potential for exposure to these substances. The use of standard traffic control measures will also minimize the interference with an emergency response or evacuation plan. What changes to the project would mitigate the identified impacts?

EWRONMENTAL EVALUATION Neroly 'S' Curve Realignment The proposed project includes the realignment of approximately 805 feet of Neroly Road, acquisition of right-of-way, removal of some orchard trees, and the relocation of roadside drainage ditches. The present configuration of the roadway does not meet existing design standards. The realignment of the existing "S" curve on Neroly-Road to meet current design standards will provide a longer radius, allowing a higher posted speed which is compatible with the posted speed north and south of the "S" curve. In the process of preparing the Checklist and conducting the evaluation, the following references (which are available for review at the Public Works Department located at 255 Glacier Drive, Martinez, except where otherwise noted) were consulted: REFERENCES: 1. Contra Costa Resource Mapping System (available at the Community Development Department). (oG( Pipe, s�=� , Zn�Z :P--c ( NL-e.T*'.� RAct'&`Z 2. The County General Plan and EIR on the General Plan (January 1991) CA 3. Negative Declaration of Environmental Significance for Subdivision #7359 4. RAREFIND - Califomia Natural Diversity Data Base (January 14, 1994) 5. Field Review (August 3, 1994) 6. California Archaeological Inventory Letter (September 13, 1989) 1. EARTH (A, D - G) Review of the County Resource Mapping System did not identify any unique geologic or physical features.I The minor grading of the surface will not result in unstable earth conditions or changes in geologic substructures, nor increase the exposure to geologic hazards. The Brentwood Fault is approximately one mile east of the project area. According to the General Plan the project area has a generally moderate to low liquefaction potential and has a moderate damage susceptibility as a result of seismic activity. However, realigning Neroly Road will not result in the exposure of people or property to geologic hazards. According to the County Resource Mapping System, Delhi Sand and Capay Clay are found in the project area. The project will temporarily increase the exposure of the soil to wind and water erosion during the construction phase, but this impact is minor and temporary. Adherence to standard dust and erosion control practices including, but not limited to general watering of exposed areas and use of chemical stabilizers will minimize this impact. Dust and erosion control measures shall be incorporated into the construction contract. (13 - C) The proposed project includes minor grading and the relocation of roadside drainage ditches. The change of ground surface relief is minor and will not result in a significant impact. Environmental Evaluation Neroly Road "S" Curve Realignment October 25, 1994 Page 2 2. AIR (A- B) Short-term emissions and objectionable odors are generated during construction activities, but they are minor and temporary. To minimize this impact, contract specifications shall stipulate the use of properly tuned and muffled equipment, and eliminating unnecessary idling of machines when not in use. Implementation of dust control practices noted in #1 - EARTH (A, D - G) will also reduce air quality impacts. (C) Realigning Neroly Road will not result in the alteration of air movement, moisture, or temperature, or any change in climate. 3. WATER (A- 1) According to the Contra Costa Resource Mapping System, the project area is not within a flood hazard area. Realigning Neroly Road will not affect any marine or fresh waters, groundwater, or flood waters. The Contra Costa Canal,which moves public water supply from the Delta westward to water customers, is on the north side of Laurel Road and is not within the project limits (see Figure 2 and 3),thus,the project will not adversely affect the quantity or quality of this, or any other public water supply. Dust and erosion control measures will prevent fugitive dust from entering the canal. The rate and amount of runoff is not expected to substantially increase due to the project's minor increase of impervious surface area. The project includes the relocation of roadside drainage ditches (see Figure 3), therefore, the project will not result in significant changes to drainage patterns in the project area. Water quality impacts will also be reduced by the use of sediment traps and/or fitters at storm drain inlets, if needed. As mentioned in #10 - RISK OF UPSET, standard construction safety practices shall be followed in order to reduce the possibility of a spill of gasoline, oil, or other pollutants which may have a significant impact on water quality. 4. PLANT LIFE (A- D) Plant life in the project area consists of non-native grassland on the west side, and an orchard of almond trees and non-native grassland on the east side of Neroly Road (see Figure 3). Several of the trees from the orchard will be removed as a result of the road realignment. Removing orchard trees does not constitute a significant impact on plant life in the project area. Environmental Evaluation Neroly Road "S" Curve Realignment October 25, 1994 Page 3 The County Resource Mapping System, Negative Declaration for Subdivision #7359, field reviews, and RAREFIND showed no unique,threatened, or endangered species of plants in the project area. The project will not result in the introduction of new species of plants into the area, nor will it create a barrier to the normal replenishment of existing species. The project will not result in the encroachment upon the habitat of any unique, threatened, or endangered species of plants. 5. ANIMAL LIFE (A - D) The non-native grassland in the project area does not contain significant habitat for animal life. The almond orchard on the east side of Neroly Road provides temporary and permanent cover, nesting, and foraging grounds for common mammals such as jackrabbits, skunks, ground squirrels, and for raptors such as turkey vulture, red-tailed hawk and American kestrel. The Resource Mapping System, Negative Declaration for Subdivision #7359, and a field visit showed no rare or endangered animal life in the area, therefore, removing trees from the orchard will not result in a significant impact to animal life. The project will not significantly change the diversity of species or the numbers of any species. No new species of animals will be introduced as a result of the project. 6. NOISE (A- B) The County Resource Mapping System for the project area indicates a noise level of 60 dBA for the year 2005. The dominant source of noise within the project area is train traffic on the SPRR and vehicular traffic on Neroly Road. Realigning Neroly Road will not move the roadway closer to any sensitive receptors. The current conditions of the roadway necessitate vehicles slow down as they enter the curve and,speed up to the posted speed as they exit the curve. Although the posted speed on the realigned roadway will increase (consistent with the speed limit north and south of the existing curve),the noise level is not expected to increase significantly due to smoother circulation (i.e., eliminating sharp curves and the need to change speeds) on the roadway (see #13 Transportation/Circulation). In general, construction activities produce noise levels of 86 dBA at 50 feet, which is well below the threshold of pain of 120-140 dBA. Best management practices noted in #2 - AIR (A - B), and limiting work hours to 7:30 a.m. - 5:00 p.m., Monday through Friday, unless modified upon written approval, reduce construction noise levels and shall be incorporated as part of the construction contract. Environmental Evaluation i Neroly Road "S" Curve Realignment October 25, 1994 Page 4 7. LIGHT AND GLARE Realigning Neroly Road will not produce any new light. Additional pavement resulting from the project will result in a minor increase in the amount of glare created, however, this is not a significant impact. 8. LAND USE The existing land use within the project limits include a vacant parcel (Subdivision # 7359), an almond orchard on the east side of Neroly Road, and a vacant parcel adjacent to the SPRR on the west side of Neroly Road (see Figure 3). A total of approximately 27,000 sq. ft. of right-of-way will be acquired from the three property owners. The road widening will not result in a significant change in land use since the right-of-way needed represents only 2% of the total area of the parcels involved. The land uses beyonj the Project limits include the Contra Costa Canal, the SPRR, single-family residential, rural residential, and agricultural. Realigning Neroly Road will not affect the land uses beyond the project limits. The realignment project is consistent with Roadway and Transit Policy #5-8 (eliminating geometric design deficiencies) and Implementation Measure #5-m (adopt design standards and right-of-way standards, based on a minimum of 12 ft. per travel lane, 12 ft. per turn lane, and 8 ft. per shoulder) outlined in the County General Plan. 9. NATURAL RESOURCES During construction, the project will use paving materials (i.e. asphalt) which will not significantly impact this resource. The use of oil and gasoline to operate the machinery for construction purposes is negligible and of a short-term, temporary nature. Best management practices noted in #2-AIR (A- B) will minimize the consumption of natural resources. Smoother circulation (see #13 - TRANSPORTATION AND CIRCULATION) would also conserve natural resources (i.e. petroleum products). 10. RISK OF UPSET (A) The County Resource Mapping System for the project area identified a petroleum pipeline along the SPRR right-of-way, however, this is outside the project limits. The proposed project has the potential to release hazardous substances, such as accidental petroleum spills, during construction. Per standard specifications, standard construction safety practices will be followed to ensure no accidental release of hazardous substances or increase the potential for exposure to these substances. Environmental Evaluation Neroly Road "S" Curve Realignment October 25, 1994 Page 5 (B) The project has the potential for interfering with an emergency response, but emergency response agencies in the area shall be notified prior to the onset of construction. During construction, it may be necessary to detour traffic or close lanes and shift traffic. Standard specifications require installing sufficient signs warning about the construction. 11. & 12 POPULATION AND HOUSING The project will not result in a change in the location, distribution, density, or growth rate of human population in the area, nor will it affect existing housing, or create a demand for additional housing (see # 8 - LAND USE). 13. TRANSPORTATION/CIRCULATION: (A - C & E) The General Plan has designated Neroly Road as an existing arterial. Realigning the road and bringing it up to current design standards will result in smoother circulation and is consistent with the County General Plan (see #8 - LAND USE). The project will not generate additional traffic, increase the demand for additional parking, alter circulation patterns or impact existing transportation systems, except during construction. (D & F) During construction, equipment may temporarily inhibit smooth circulation, but traffic control, such as flagging, warning signs and temporary detours, will minimize this impact. No work which could interfere with commute traffic shall be performed before 8:30 a.m., nor after 4:30 p.m., when traffic is to be diverted within the Neroly Road right- of-way. Transportation and circulation impacts are temporary, minor, and insignificant, and will end upon completion of the project. 14. PUBLIC SERVICE (A - D, F) The proposed project will not increase the need for fire or police protection, schools, parks, or other governmental services (see #8 - LAND USE, #11 - POPULATION, and #12 - HOUSING). (E) Neroly Road is currently maintained by the County and periodic maintenance of the realigned roadway will continue to be performed by the County. Environmental Evaluation Neroly Road "S' Curve Realignment October 25, 1994 Page 6 15. ENERGY (A & B) Minor amounts of non-renewable fuel resources will be consumed during construction, but this is a short-term, temporary and minor impact. Eliminating unnecessary idling of machines when not in use and using properly tuned equipment, as mentioned in #2- AIR (A- B) and #9 - NATURAL RESOURCES, will further minimize the consumption of energy resources. As mentioned in #9 - NATURAL RESOURCES, smoother circulation on Neroly Road (see#13-TRANSPORTATION AND CIRCULATION) would also conserve natural resources (i.e. petroleum products). 16. UTILITIES The proposed project may require the relocation of various utilities, however this is not a significant impact. All relocation activities shall be coordinated with the appropriate utility agencies. 17. HUMAN HEALTH (A & B) The proposed project has the potential to release hazardous substances during construction. Potential health hazards due to accidental petroleum spills shall be minimized by following best management practices noted in #10 - RISK OF UPSET (A). Degradation of air quality, which could affect human health, can be minimized by the measures noted in #2 - AIR. The proposed project will not create any known health hazard or increase the potential for exposure. 18. AESTHETICS Realigning Neroly Road will not result in the obstruction of any scenic vista, nor will it result in the creation of an aesthetically offensive site. Several almond trees will be removed from the orchard on the east side of Neroly Road. The orchard trees do not contribute significantly to the aesthetics of the area, therefore, removing them is not considered a significant impact. 19. RECREATION According to the Contra Costa Resource Mapping System, Neroly Road, north of Laurel Road, is designated as a combination (hiking, bicycle, equestrian) trail. However, the combination trail has not been constructed,therefore,construction activities will not result in a significant impact. No other recreational opportunities exist within the project limits. Environmental Evaluation Neroly Road "S" Curve Realignment October 25, 1994 Page 7 The combination trail along the Contra Costa Canal will not be affected by construction activities. 20. CULTURAL RESOURCES (A - D) The County General Plan indicates that the project site has a medium sensitivity level, however, a search of the California Archaeological Inventory records indicate the project area has a low probability of cultural resources. According to the County Resource Mapping System, no historical or archaeological sites exist in the project vicinity.
