Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-1 January 25, 2005 Chapter 3. Public Facilities A. OVERVIEW The Coffee/Claratina Specific Plan area infrastructure system is an extension of the existing neighborhood area's infrastructure. Buildout of the plan area was planned for as part of the existing neighborhood planning areas. This chapter describes development of the transportation and circulation, wastewater collection, water delivery, storm water drainage, utilities (electricity, street lighting, natural gas, telephone, cable television, irrigation, solid waste collection), schools, and parks and recreation necessary to support development in the Plan Area. Improvement of Coffee/Claratina infrastructure will be as described in the General Plan policies in Chapter V, Community Services and Facilities of the Modesto Urban Area General Plan. B. INFRASTRUCTURE PLAN The Coffee/Claratina Infrastructure Plan is shown on Figures 6, 7 and 8. The figures serve as a design schematic for the planning area infrastructure and does not represent specific alignments or locations for facilities. Sub-area boundaries as shown on Figure 5 will not affect the ability to provide infrastructure to the area. The figures indicate the preliminary sizing and design for backbone infrastructure in the planning area. Exact phasing and design will be determined as development occurs. Prior to the recording of subdivision maps, improvement plans consistent with the general design in this Specific Plan shall be approved by the City. 1. Sanitary Sewer Service (See Figure 6) The existing 18" subtrunk sewer main at Coffee Road and Sylvan Meadows Drive will be utilized to serve the North Beyer Park Plan Area. A sewer lift station will be installed in order to obtain the depth required to accommodate the expected construction and build-out of the Plan Area. A "sub-trunk" sewer line has been extended from the pump station through the Specific Plan area as shown on Figure 6. The pump station and the eight-inch sewer line and twelve-inch "sub-trunk" sewer system in Grecian Avenue and Coffee Road have been sized to serve the Coffee/Claratina Plan Area. The "sub-trunk" system and sewer lift station and force main shall be funded by the City with fees collected for that purpose. A 10" sanitary sewer line exists in McHenry Avenue, terminating at Coralwood Avenue. If capacity is available, sewer connection to this line in McHenry Avenue may be an alternative to connecting to the sewer line in Grecian Avenue to serve west portion of the Specific Plan area. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-2 January 25, 2005 The overall sewer facilities needed to serve the Specific Plan Area consist of approximately: One lift station on Coffee Road 700 LF of 30" sewer line 2100 LF of 12" sewer line 2100 LF of 15" sewer line 600 LF of 8" sewer line 2. Storm Drainage (See Figures 8 and 8A) The City has created a master plan for storm drainage to serve the Coffee/Claratina area along with the area to the north and to the east. The master plan requires a regional basin be constructed to serve this area (see Figure 8A). A positive storm drainage system comprised of catch basins, pipelines and storm drain basins is proposed to serve this project (see Figure The storm drain basins will be incrementally constructed as development occurs. The storm drain collection system and basins will be designed in accordance with the City of Modesto Standards and specifications. Exact locations may vary, depending on sub-area annexation to the City. The storm drain basin in the west half will serve the Regional Commercial, Residential and the Modesto Mobile Home Park (Sub-Areas A & B1) and be installed incrementally with the development of the Regional Commercial Area. In the east half the basin will be fully installed prior to any residential development and serve Sub-Areas B2 and C. The overall storm drainage facilities needed to serve the Specific Plan Area consist of approximately: One storm drain basin in area B1 of 10-11 ac/ft capacity One storm drain basin in area B2 of 6-7 ac/ft capacity 1000 LF of 18" storm drain line 1000 LF of 24" storm drain line 3. Water (See Figure 7) City water service will be provided to the entire plan area through connection and extensions of the existing water 12" main in Claratina Avenue, west of Coffee Road. The existing 12" water main and a 24" transmission water main which lie in Claratina Avenue are part of a larger looped water system designed to serve the entire Plan Area. Water system should be looped to tie in with existing water lines in Dragoo Park Drive and Drakeshire Drive. All private wells located on any individual parcel slated for development shall be abandoned and capped at the time of development, in accordance with the City of Modesto, Stanislaus County and Department of Health Service Standards. In 2004, Public Works Department required a water capacity study to determine the best water source for undeveloped portions of the specific plan area. The water study may require that future development may be required to pay its fair share of any new water source. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-3 January 25, 2005 The overall water facilities needed to serve the Specific Plan Area consist of approximately: 4700 LF of 12" water line 1400 LF of 10" water line C. TRANSPORTATION AND CIRCULATION 1. Overview The Coffee/Claratina Plan Area circulation system represents a logical extension of the City's existing arterial and collector street system as specified in the General Plan. The location and classification of streets within this extended street system is shown on Figure 9, Circulation Plan. The plan provides for the dedication of right-of- way that is required within Coffee/Claratina Plan Area for the proposed Pelandale Expressway (Claratina Avenue) based on current City standards. Additional dedication for the expressway will be required by the properties north of the Plan Area as future development occurs. 2. Specific Plan Street Classifications Table 2 (below) Specific Plan Street Classifications, describes the streets which are a part of the Coffee/Claratina Plan Area. The street classifications correspond to Public Works Standards. Street cross-sections shall conform to Public Works Standards and policies with the following exception, the Pelandale Expressway (Claratina Avenue) shall be as shown in the diagram below. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-4 January 25, 2005 Table 2 - Specific Plan Street Classifications Street / Classification Street R.O.W. Class B Expressway (Pelandale Expressway) 6 Travel Lanes 135 Feet 159 feet at Intersections Principle Arterial (McHenry Avenue - State Hwy. 108) 8 Travel Lanes 138 Feet 159 feet at Intersections Minor Arterial (Coffee Road) 4 Lanes 100 Feet 120 feet at Intersections Collector Street (Dragoo Park & Drakeshire Drive) 60 Feet Future E/W Collector 2 Lanes/4 Lanes 60/100 Feet Minor Residential Street 50 Feet The future east-west collector will be a four lane major collector in the Regional Commercial area and a two lane minor collector in the Residential area. a. Class B Expressway - Claratina Avenue is designated as an expressway in the General Plan. Public Works analysis has determined Claratina Avenue to be an eastward extension of the Pelandale Expressway to be developed to a 135 foot (6 lanes) Class B Expressway (159 feet at Intersections). The Expressway will ultimately connect from Highway 99 to the Roselle Avenue. The expressway shall include a Class I Bike Path that will link up with the Claratina and Claus Road paths consistent with the City of Modesto's Non-Motorized Transportation Master Plan. As property owners develop within the Plan Area they will be required to dedicate right-of-way for the expressway and construct a sound wall along the property adjacent to the expressway. b. Arterial Streets - The extension of two arterial streets, Coffee Road and McHenry Avenue (State Hwy. 108) are part of the City's circulation system. Coffee Road shall include a Class II Bike Lane consistent with the City of Modesto's Non-Motorized Transportation Master Plan. Coffee Road will be improved as a 100' minor arterial and McHenry Avenue will be a 138' principle arterial per Public Works Standards. Additional right-of-way may be required on the McHenry Avenue frontage and the Coffee Road frontage near their intersection with the new east-west collector to allow for the construction of dual southbound left turn lanes. c. Collector Streets - A new east-west collector street should be developed from McHenry Avenue, through proposed commercial, and residential areas, to Coffee Road. This collector should be situated as far south as possible, near existing developed areas. However, this collector road shall not be extended through the existing Silverwood Mobile Home Park located within Sub-area C. The new east- ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-5 January 25, 2005 west collector will be a four lane major collector in the Regional Commercial area and a two lane minor collector in the Residential area. The intersection of the new east-west collector street with McHenry Avenue will include a minimum of two receiving lanes, two left turn lanes and one right turn lane. At the time of the review of any specific development request, the City of Modesto Transportation Division will evaluate whether another right turn lane is needed. Dragoo Park Drive and Drakeshire Drive should terminate at the proposed east- west collector. The Dragoo Park intersection to the east-west collector will be offset a minimum of 200 feet from the intersection of the right-in/right-out access road to Claratina Avenue with the east-west collector. The new east-west collector street will be terminated at its intersection with Coffee Road at the mid point between Claratina and Mable Avenues with right-in and right-out only (per Figure The City of Modesto Transportation Division will determine the specific intersection geometrics at the time of a specific development request affecting this intersection. A short collector street should connect the east-west collector from west of Dragoo Park Drive to the proposed Pelandale Expressway (Claratina Avenue) with "right-turn in" and "right-turn out" only. Developers should minimize the amount of lots having direct access to collector street frontage. d. Minor Residential Streets - Minor residential streets provide internal neighborhood circulation while minimizing through traffic. This street network will be determined at the time each individual property owner develops. No connection will be permitted between minor residential streets and the proposed Claratina Expressway through the planned residential areas. e. Non-Motorized Transportation Master Plan - Bike paths shall be installed on expressways, arterials and the Hetch-Hetchy Aqueduct consistent with the City of Modesto's Non-Motorized Transportation Master Plan. Along Claratina Avenue, landscaped areas will be constructed by the City and will include a meandering Class I Bikepath with 8” wide landscaped areas. D. TRAFFIC CIRCULATION SYSTEM ANALYSIS The following outline shows general traffic circulation system improvement needs anticipated for the next 30 years based on the Traffic Impact Analysis prepared by KDAnderson Transportation Engineers. These needs cover areas adjacent to and outside the project area. A majority of these improvement would be needed even without this project. A listing of these needs does not indicate the project responsibility which can be found in the Coffee/Claratina Financing Plan. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3.

SCHOOLS The Coffee/Claratina project will be served by the Sylvan Union School District for grades Kindergarten through 8, and by the Modesto High School District for 9-12. As stated in the City's General Plan (Policy V.H.3.i, Page V-25), the City considers impacts on public school capital facilities fully mitigated when it receives a letter stating that the school district and project proponent have resolved school impacts and the means by which they are resolved. This agreement will be required prior to recordation of final maps or plot plan approvals. F. PARKS In Modesto, open space is provided though a comprehensive network of regional, community and neighborhood parks. The Coffee/Claratina Specific Plan is the remaining portion of an existing neighborhood and lies within Park Planning Area No. 8 as shown on Figure V-5 of the General Plan. There are no existing parks within the existing neighborhood, and a neighborhood park shall be provided within the planning area. The Park should be centrally located and have one collector street frontage with the remaining side fronting on residential streets, whenever feasible. Payment of capital facilities fees will mitigate the projects impact to parks and open space demand in the area. The minimum size for a neighborhood park shall be seven acres. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-8 January 25, 2005 When a public elementary or junior high school or schools are located within a Park Planning area, up to five acres of open space, at each school which is developed, maintained and is accessible to the public for outdoor recreation activities, may count toward satisfying the Neighborhood Park standard of two acres of Neighborhood Park land per one thousand population within the Park Planning Area. However, regardless of the number of public school open space acres within a Park Planning Area, the City will provide a minimum of one City neighborhood park of seven acres. G. GAS FACILITIES Pacific Gas & Electric (PG&E) owns an approximately one-third (1/3) acre parcel, within the Specific Plan area, south of and adjacent to the existing Claratina Avenue right-of-way approximately 180 feet east of the centerline intersection of Claratina Avenue and Coffee Road. This site contains a gas regulator station. Entering into the gas regulator station from the west in Claratina Avenue are 8- inch and 12-inch gas transmission lines. These facilities enter into the regulator station and then, through a series of valves and distribution facilities, exit the facility as 8-inch and 10-inch gas transmission lines which continue east in Claratina Avenue and then north in Coffee Road to serve the communities of Riverbank, Oakdale and Escalon, and 8-inch and 12-inch gas transmission lines continuing east on Claratina Avenue and then south in Coffee Road to serve the City of Modesto. Widening Claratina Avenue to a 100-foot right-of-way on its existing alignment could require the relocation of eight mainline valves and five blow-off valves. If additional right of way is required from the centerline of Claratina Avenue, it is possible that more substantial facilities would need to be relocated which could ultimately require the relocation of the entire facility. Ultimately, the City will determine whether or not this facility ultimately needs to be relocated, or whether the Claratina alignment or section can be modified in such a way that the facility can remain, or modification can be minimal. H. ELECTRICAL FACILITIES Modesto Irrigation District (“MID”) has existing 12kv overhead and underground distribution facilities located within or adjacent to Coralwood Road, McHenry Avenue, Claratina Avenue and Coffee Road with additional facilities that extend into various properties within the proposed Specific Plan area. Facilities will be relocated, placed underground, or otherwise modified consistent with MID and City of Modesto standards. Individual development requests will be analyzed to determine the most appropriate method of providing electrical service. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3. Public Facilities City of Modesto 3-9 January 25, 2005 I. IRRIGATION FACILITIES Underground irrigation facilities exist at the site. Individual development requests will show the location of existing irrigation facilities and how they will be abandoned or relocated. All facility abandonment or relocation will be consistent with Modesto Irrigation District and City of Modesto standards. ---PAGE BREAK--- Coffee/Claratina Specific Plan Chapter 3.
