D. CITIES AND COUNTY Local government uses the general plan process required by California law to guide land use and other municipal functions that may affect the physical and social environment. The District has a unit dedicated to local government coordination. 1. Interlocking Jurisdiction The creeks and other facilities under the jurisdiction of the Santa Clara Valley Water District are important parts of the environment of the cities and the County of Santa Clara. Although the District's facilities are embedded within the lands of other jurisdictions (County and cities), the District is a separate public agency, and maintenance activities are not subject to city or County general plans or other local ordinances. Likewise, the District has no authority or control in land use, even though land use affects the District's flood protection or maintenance work. The District coordinates its flood protection work with cities and the county General Plan Land use documents. The District completed a comprehensive hydrologic analysis to determine flow rates in the creeks within the county in the late 1970's. This analysis was based on land uses and densities shown in the general plans of the cities and counties at that time. Many flood protection projects have been constructed throughout the valley using flow rates, if not measures along an entire creek, then at downstream reaches of the creek. General Plans are subject to change and as the county develops, land use densities and flow rates have increased. The increase in flow rates and channelization can impact the capacity of completed flood protection facilities. The changes in land use and increases in runoff can also increase depths of flooding or the lateral extent of flooding show on existing flood maps, as these maps were prepared using the land uses shown on the 1970's General Plans. This Section lists those portions of General Plans, and some other local ordinances and policies which are relevant to flood protection and new development within the floodplains and channels in the District. 2. Projected Work in Cities and County The overlap between projected District maintenance and local jurisdiction indicates the potential effect on cities. Table III-3 shows the total length of creek in each jurisdiction. Sediment removal and vegetation management frequently occur in similar places, though vegetation management activities also occur at other locations outside of streams. Table III-3 Creeks and Projected Work in Cities and County
Many of the creeks form jurisdictional boundaries, so that one reach of creek is in two jurisdictions and is counted twice. Due to dual jurisdiction and double-counting, the total of jurisdiction tables is greater than the total length of creeks. The source of the information presented in Table III-3 is a comparison between the District creek system and the boundaries of the cities in a geographic information system. Where creeks form the legal boundary of a city, there is often a different mapped location of the creek -- due to different surveying and mapping or sometimes to major movement of the channel away from the historical location that constituted the city line. Because of the mapping differences, the lengths of creek in Table III-3 may not equal the lengths on record in the individual cities, but they adequately indicate the magnitude of potential effect. Overall, most of the District's projected routine stream and canal maintenance work is in Cities, as opposed to within unincorporated areas of the County. In the lower watershed, roughly 40% (223 miles) of the creeks are unincorporated areas. The SMP purpose is to maintain protection of already established urban areas. Thus considering actual projected maintenance work, the focus on established city jurisdiction is more pronounced. Most of the sediment removal/vegetation management work and of the bank protection work would likely be performed within existing city boundaries. 3. General Plan Policies All of the general plans from the cities in Santa Clara County and the County itself have goals and policies that pertain to creeks and riparian areas which address restoration, enhancement and use of the creeks (see Table III-4, Local General Plan Policies for Streams). This analysis summarizes the provisions of local general plans that address the stream environment and the issues surrounding District stream maintenance. Local policy is continually evolving; this discussion is based on a summary made available for review by city planning staff in December 2000. This section first summarizes General Plan policies that are relevant to the maintenance Program itself, followed by a discussion of policies relating to new development in areas adjacent to or upstream from channels that may affect the future need for maintenance. a. Santa Clara County 1) Policies Directly Relevant to District Maintenance Activities Santa Clara County has policies in its Parks and Recreation, Resource Conservation and Health and Safety General Plan elements that pertain to lands that are under the District's jurisdiction. Strategies that are listed under these policies include: HEALTH AND SAFETY POLICY C-HS 34. Flood control measures should be considered part of an overall community improvement program and advance the following goals, in addition to flood control: a) resource conservation; b) preservation of riparian vegetation and habitat; c) recreation; and d) scenic preservation of the county's streams and creeks. HEALTH AND SAFETY POLICY C-HS (I) 32. Continue efforts by, and joint planning with, the Santa Clara Valley Water District to design and construct flood control improvements that achieve a desirable balance of resource conservation, flood control and recreational objectives Consistency: The proposed Program provides for maintenance of flood carrying capacity in areas within the District's jurisdiction. The proposed Program would advance the goals of the County to achieve a desirable balance of resource conservation, flood protection and recreational objectives. 2) Other policies relevant to waterways. Goals and policies are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: RESOURCE CONSERVATION, POLICY C-RC 26. Comprehensive watershed management plans should be developed and implemented through intergovernmental coordination. Water supply watersheds should receive special consideration and additional protection. RESOURCE CONSERVATION, POLICY C-RC (I) 8. Encourage Task Force Participation by Appropriate Agencies, Districts, And Jurisdictions to Scope And Develop Management Plans. (Lead Agencies: SCVWD And The City of San Francisco Public Works). Consistency: Comprehensive watershed management jointly by the District and the local agencies which incorporated mutual objectives and integrated land use planning with flood protection and maintenance for flood protection would facilitate protection and enhancement of creek resources and would reduce the District's long-term responsibilities for both engineered flood protection and maintenance. HEALTH AND SAFETY POLICY C-HS 30. Local jurisdictions' urban development and land use policies should minimize the resident population within areas subject to high natural hazards in order to reduce: a) the overall risk to life and property; and b) the cost to the general public of providing urban services and infrastructure to urban development. HEALTH AND SAFETY POLICY C-HS (I) 30. Continued adherence to joint urban development policies and exclusion of areas unsuited for urban development from Cities Urban Service Areas. HEALTH AND SAFETY POLICY R-HS 8. Areas of persistent flooding and areas of potential inundation from dam failure shall generally be designated for agricultural land uses or other suitable open space use. HEALTH AND SAFETY POLICY R-HS 9. Development in rural unincorporated areas affected by natural hazards should be designed, located, and otherwise regulated to avoid or reduce associated risks to an acceptable level: 1. In areas of highest potential hazard, such as floodways, active landslides, fault traces, and airport safety zones, no new habitable structures shall be allowed. 2. In other areas of lesser hazards, there shall be no major structures for involuntary occupancy, such as schools, hospitals, correctional facilities or convalescent centers . Relevance to the proposed Program: There are Goals and Policies listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels, such as limiting impervious surfaces and/or providing storm water detention ponds. The County deals with this through the existing Grading Ordinance and the development permitting process (Bill Shoe, Advance Planning, personal communication). The District's Stream Maintenance operations do not conflict with any of the goals listed in the County's General Plan. Most of the policies in the General Plan pertain to new growth and development; routine maintenance activities undertaken by the District do not affect new development. However, new development in upslope or hillside areas which drain towards creek channels may cause runoff and erosion problems, and may impact existing flood protection facilities. These two concerns are identified in the Health and Safety section of the General Plan, and there are implementation recommendations for continuing efforts with the District to design and construct flood protection improvements. Table III-4 Local General Plan Policies for Streams
b. City of Campbell The City of Campbell has policies in the Land Use, Conservation and Open Space General Plan elements that pertain to lands that are under the District's jurisdiction. As stated in the City's General Plan, the City "is in a rather unique position in relation to other cities in Santa Clara County in that it is surrounded by a relatively uniform urbanized area, and it is already largely developed. Essentially, the only remaining natural resources in Campbell are those water resource areas associated with the percolation ponds and the flood protection channels. In addition to serving flood protection and groundwater recharge zones, these areas also serve as recreational areas and wildlife habitats" (City of Campbell General Plan, 1990 p. 80). Goals and Objectives include: 1) Policies particularly relevant to District maintenance activities CONSERVATION ELEMENT POLICY 1. The City shall assist in preventing, controlling and correcting the erosion of creek and flood control banks.
SAFETY ELEMENT POLICY 5. The City shall support flood control improvements that will reduce serious flood hazards. Consistency: The proposed Program would assist in preventing, controlling and correcting the erosion of creek and flood protection banks. The proposed Program would preserve, through routine maintenance, flood protection functions that could reduce the risk of serious flood hazards. 2) Other policies relevant to waterways Goals, policies and implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: CONSERVATION ELEMENT AND NATURAL RESOURCES ELEMENT, STRATEGY CNR- 1.1b: Archaeological Resources: In accordance with CEQA and the State Public Resources Code, require the preparation of a resource mitigation plan and monitoring program by a licensed archaeologist if archaeological resources are found on any sites within the City. CONSERVATION AND NATURAL RESOURCES ELEMENT, Goal CNR-3.1: Riparian Corridor Preservation: Protect and maintain animal and plant species and supporting habitats within Campbell. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1a: Development Near Riparian Corridors: Cooperate with State, federal and local agencies to ensure that development does not cause significant adverse impacts to existing riparian corridors. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1b: Santa Clara Valley District Activities: Work with the Santa Clara Valley Water District to restrict future fencing, piping, and channelization of creeks when flood control and public safety can be achieved through measures that preserve the natural environment and habitat of riparian corridors. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1c: Native Species Planting: Encourage the Santa Clara Valley Water District and County Parks Department to plant and maintain native trees and plants and replace invasive, non-native species with native ones along creek corridors. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1d: Removal of Invasive Species: Institute an on-going program to remove invasive plant species and harmful insects from ecologically sensitive areas, primarily by means other than application of herbicides and pesticides. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1e: Concrete-lined Channels: Coordinate efforts with the Water District to revert some existing concrete-lined channels to more natural alternatives such as levees. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-3.1f: Grading Ordinance: Develop and implement a Grading Ordinance that minimizes grading and vegetation removal near creeks to ensure that the creeks are protected from reduction in bank stability, erosion, downstream sedimentation and flooding. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-5.1d: Sediment Removal from Creeks: Work with Santa Clara Valley Water District on sediment management for the creeks. CONSERVATION AND NATURAL RESOURCES ELEMENT, Strategy CNR-5-1e: Dumping into Waterways: Work with the Santa Clara Valley Water District to protect surface water quality by prohibiting the dumping of toxic chemical substances, debris and refuse in and near waterways and storm drains and add signs with this information near these areas. OPEN SPACE ELEMENT, PUBLIC PARKS AND FACILITIES GOAL OSP-1: Regional open space, parks and recreation facilities that are useful, attractive, well-maintained and accessible to Campbell residents. OPEN SPACE ELEMENT, PUBLIC PARKS AND FACILITIES POLICY OSP-1.1: Regional Open Space, Park and Recreation Facilities: Support efforts to enhance and enlarge regional open space, parks and recreation facilities and to provide access to regional facilities for Campbell residents. OPEN SPACE ELEMENT, PUBLIC PARKS AND FACILITIES STRATEGY OSP-1.1b:Santa Clara Valley Water District: Work with the Santa Clara Valley Water District to provide public access and improvements to the Groundwater Recharge Facilities in the City and explore the possibility of a recreational trail along San Tomas Aquino Creek. OPEN SPACE ELEMENT, PUBLIC PARKS AND FACILITIES STRATEGY OSP-1.3a: Maintenance & Use Agreements: Enter into maintenance and use agreements with the County of Santa Clara and the Santa Clara Valley Water District to increase the usability of and provide better access to these park lands and facilities. Relevance to the proposed Program: Implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. The General Plan identified participation in the National Flood Insurance Program, and maps released by the Federal Insurance Administration support the contention that the present condition of the stream channels can carry the runoff from the "design flood" without adversely affecting the City. The proposed Program would preserve existing levels of flood protection for each stream. The General Plan identifies specific goals related to the Santa Clara Valley Water District, for water quality, bank stability, and habitat conservation/enhancement. The Stream Maintenance Program complements and supports these goals. c. City of Cupertino The City of Cupertino has policies in the Land Use/Community Character, Environmental Resources, and Public Health and Safety General Plan elements that pertain to lands that are under the District's jurisdiction. Stevens Creek, Permanente Creek, Regnart Creek and Calabazas Creek cross through the City of Cupertino, and the General Plan states that "Stevens Creek and its streamside are among the natural elements that have the most influence on Cupertino's character. The creek strongly defines the boundary between the urban and rural parts of the City, extends a note of unspoiled beauty into the heart of the developed valley floor and gives many residents and visitors a space for play, relaxation or study of the creek's plant and animal life" (Cupertino General Plan, 1993, pp. 2-39). Major goals and policies include: 1) Policies particularly relevant to District activities ENVIRONMENTAL RESOURCES, GOAL D. Preserve and protect special areas of natural vegetation and wildlife habitation as integral parts of the environment. ENVIRONMENTAL RESOURCES, POLICY 5-28. Retain creek beds, riparian corridors, water courses and associated vegetation in their natural state to protect wildlife habitat and recreation potential and assist groundwater percolation. Consistency: The proposed Program contemplates sediment removal and/or vegetation management and bank protection work within the City of Cupertino. The Stream Maintenance Program complements and supports the above goals. 2) Other policies relevant to waterways Goals, policies and implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: ENVIRONMENTAL RESOURCES, GOAL E. Protect and conserve water resources as they are vital to the environmental and economic health of Cupertino. ENVIRONMENTAL RESOURCES, GOAL F. Strive to minimize the quantity and improve the quality of storm water runoff consistent with the protection of groundwater quality and groundwater recharge areas. ENVIRONMENTAL RESOURCES, GOAL G. Preserve and acquire open space lands for the preservation of natural resources, the managed production of resources, for outdoor recreation and for public health and safety. ENVIRONMENTAL RESOURCES, POLICY 5-14. Encourage the clustering of new development away from sensitive areas such as riparian corridors, wildlife habitat and corridors, public open space preserves, and ridgelines. ENVIRONMENTAL RESOURCES, POLICY 5-14, STRATEGY. Consider specific protection tools for riparian corridor protection, such as a riparian corridor ordinance or development and preservation guidelines. ENVIRONMENTAL RESOURCES, POLICY 5-18. Limit recreation in natural areas to activities compatible with preserving natural vegetation, such as hiking, horseback riding and camping. ENVIRONMENTAL RESOURCES, POLICY 5-19. Provide public access to wildlife observation and fishing sites consistent with preserving important wildlife habitat. ENVIRONMENTAL RESOURCES, POLICY 5-20. Provide open space linkages within and between properties for both recreational and wildlife activities, most specifically for the benefit of wildlife which is threatened, endangered or designated as species of special concern. ENVIRONMENTAL RESOURCES, POLICY 5-20, STRATEGY. Amend the RHS ordinance to require identification of creeks and water courses on site plans and require that they be protected from adjacent development. The ordinance could state that trail easements for trail linkages may be required if analysis determines that they are needed. ENVIRONMENTAL RESOURCES, POLICY 5-40. Work to keep the watershed and storage basin properties of Stevens Creek Reservoir in public ownership if the Santa Clara Valley Water District decides to abandon it. LAND USE/COMMUNITY CHARACTER, GOAL E. Protect the environment and the personal safety of the City's residents. LAND USE POLICY 2-43. Lots in major subdivisions in the 5-20 slope density designation shall be clustered, reserving 90% of the land in private open space to protect the unique characteristics of the hillsides from adverse environmental impacts. The project shall keep the open space area contiguous as much as possible LAND USE POLICY 2-43, STRATEGY. Change the Municipal Code to include this requirement. Require that significant natural features, such as vegetation, slopes over 30%, creeks and water courses, faults, landslides and prominent ridgelines be shown so that the area for clustered development can be determined. Require an open space easement or an open space zoning district on the 90% undeveloped area LAND USE POLICY 2-61. Allow commercial and recreational uses which are exclusively within the floodplain to remain in their present state or to be used for agriculture. LAND USE POLICY 2-61 STRATEGY. Designate non-recreation properties to become residential with up to five units allowed under these conditions: a. Forbid structures designed for forced human habitation, such as dwelling units, in the natural flood plain. The natural flood plain is defined by the General Plan based on data from the Santa Clara Valley Water District. Unfenced volleyball courts, picnic tables and similar recreational uses may be constructed within the natural flood plain. b. Base the maximum number of dwelling units allowed on each property
or group of properties on the numerical designation range on the General
Plan Map. Land in the flood plain can be credited in an amount not to
exceed one dwelling unit per gross acres to determine the number of
dwelling units on each property or group of properties consolidated
into one development plan. If part of the parcel is outside the flood
plain, the maximum density will be six dwelling units for each gross
acre. This policy makes it impossible for a relatively small parcel
to get a high density status as a result of one dwelling unit per acre
density credit from a relatively large area within the flood plain.
The total number of units allowed will be based on the ability of the
applicant and designer to integrate the development into the natural
environment of Stevens Creek and the adjacent residential neighborhoods.
c. Require residential development plants to incorporate the Stevens Creek trail described in the public parks section of the General Plan. LAND USE POLICY 2-62. Allow public and quasi-public land in the natural flood plain after review of a specific zoning or use permit application. PUBLIC HEALTH AND SAFETY, POLICY 6-20. Adopt stringent land use and building code requirements to prevent new construction in already urbanized flood hazard areas recognized by the Federal Flood Insurance Administrator. For example, the finished floors of new construction must be higher that the water level projected for the 100-year flood. A description of flood zone regulations and a map of potential flood hazard areas will be published in the Cupertino Scene. PUBLIC HEALTH AND SAFETY, POLICY 6-21. Continue the policy of prohibiting all forms of habitable development in natural flood plains. This includes prohibiting fill materials and obstructions that may increase flood potential downstream or modify natural streamsides. Removing sediment from drains is one of the major expenses of the City and the water district. The sediment is caused by natural erosion as well as erosion induced by development, mostly in the hillsides. The City's Hillside Development Ordinance requires private hillside construction to install bank protection measures on all cut-and-fill slopes including roadways, driveways, and house pads. Sediment increases flood risks and clogs the natural percolation function of streambeds which replenish the groundwater table (Cupertino General Plan, 1993, pp. 6-25). PUBLIC HEALTH AND SAFETY, POLICY 6-22. Continue to restrict the extent and timing of hillside grading operations to April through October. Require performance bonds during the remaining time to guarantee the repair of any erosion damage. All graded slopes must be planted as soon as practical after grading is complete. Relevance to the proposed Program: The proposed Program would provide a benefit to the City of Cupertino by ensuring that the District's channels would contain flows from the 100-year or design flood. d. City of Gilroy The City of Gilroy has policies in the Natural Environment and Parks and Recreation General Plan elements that pertain to lands that are under the District's jurisdiction. Both Uvas Creek and Llagas Creek transverse the Planning Area of Gilroy. Policies include: 1) Policies particularly relevant to District activities CONSERVATION AND OPEN SPACE, POLICY 25. Measures to reduce flood damage to individual properties will only be undertaken where the potential for hazard due to flood erosion is not increased on other properties. Consistency: By providing routine maintenance activities to creeks within the City of Gilroy, the District will assist the City in reducing the potential for flood damage to individual properties without increasing the potential for hazard from flooding on other properties. Goals, policies and implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: CONSERVATION AND OPEN SPACE, POLICY 27. In preference to steep banked trapezoidal channels, new drainage channels should be designed with gently sloping and curving banks to maximize safety, ease of maintenance, and natural appearance. In place of extensive rock riprap or concrete lining, riparian vegetation should be employed to the greatest extent feasible to stabilize channel banks. Drainage channels should be landscaped in a manner which is natural in character and which requires a minimum of maintenance to provide a scenic asset to the overall city landscape. PUBLIC SAFETY AND SEISMIC SAFETY, IMPLEMENTATION POLICY X. Encourage efforts by the Santa Clara Valley Water District to design and implement flood control measures that support and reflect the policy goals of the General Plan, including conservation, protection of flora and fauna habitats, and open space. CONSERVATION AND OPEN SPACE, POLICY 2. The City will preserve natural resource and wildlife habitat areas, reduce risk in hazardous areas and provide recreational opportunities by preserving the following areas in open space: natural resources - such as the Uvas Creek and Llagas Creek riparian communities, the heavily vegetated portions of the Santa Cruz mountains, and several stands of trees along Miller Avenue and trees bordering Hecker Pass. hazardous areas - such as fault zones and floodways. recreational land - community, neighborhood and linear parks, expanded linear parks along Uvas and Llagas Creek, and the golf course. Consistency: The Stream Maintenance Program includes sediment work in Gilroy's jurisdiction. The District will assist the City of Gilroy in meeting these goals through the BMPs that include resource protection proposed for this Program and listed in this EIR. 2) Other policies relevant to waterways Goals, policies and implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: CONSERVATION AND OPEN SPACE, POLICY 3. The ecological, aesthetic and recreational values of the creeks which flow through the Gilroy Planning Areas will be protected from urban encroachment and degradation. New development will preserve the function of natural drainages, including small canyons and seasonal creeks. The easements and setbacks adjacent to these creeks will be maintained in open space. CONSERVATION AND OPEN SPACE, POLICY 4. Clustering of new development on open grasslands and on gentler slopes rather than in areas such as wooded canyons, bluff faces, riparian zones and steep hillsides will be encouraged in order to protect the value and scenic beauty of natural drainages, watersheds, soil-holding vegetation, and native vegetation and wildlife habitats. CONSERVATION AND OPEN SPACE, POLICY 20. Development will be restricted on steep slopes, and slopes susceptible to landslides and soil creep. Slopes of 10% to 30% are suitable only for low intensity development. Slopes greater than 30%, areas of high landslide risk, and areas with highly expansive soils on slopes greater than 10% will remain in open space. CONSERVATION AND OPEN SPACE, POLICY 21. All construction activities will be based on a site plan that provides for necessary methods of erosion and deposition control throughout the various stages of actual site development and use. CONSERVATION AND OPEN SPACE, POLICY 22. Urban development and expansion shall be restricted in areas subject to major flooding, drainage problems and saturated soil conditions unless measures to reduce these hazards to acceptable levels are provided. CONSERVATION AND OPEN SPACE, POLICY 23. In preference to the construction of expensive flood prevention facilities, flood ways will be left open for agriculture and recreational use in areas of particular risk and where protection is minimal. CONSERVATION AND OPEN SPACE, POLICY 24. Measures to reduce flood hazards should minimize long term public costs and mitigate adverse effects on vegetation and wildlife corridors. CONSERVATION AND OPEN SPACE, POLICY 26. Flood control measures and drainage channel improvements should be designed as part of an overall community improvement program with provision for multiple use, including recreational open space, trails, bikeways, groundwater recharge, protection and restoration of riparian vegetation and wildlife habitats, and enhancement of scenic qualities. CONSERVATION AND OPEN SPACE, POLICY 28. The City will encourage new development to provide greenbelts for reducing runoff and increasing runoff absorption capacities. CONSERVATION AND OPEN SPACE, POLICY 29. To minimize absorption losses and storm runoff increases, the City will encourage removal of pavement not directly needed for traffic or parking needs, maintenance of unpaved parkways between sidewalks and streets, the use of permeable paving, and a break-up of large paved areas with landscaped strips and islands. CONSERVATION AND OPEN SPACE, POLICY 30. In their natural state, the hills absorb rain runoff and help protect the lowland from flood hazards. Native vegetation in hillside terrain reduces erosion and slows the speed of rainfall runoff. Any proposed development must demonstrate how these features are protected. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY B. Permit agricultural uses and structures in the open-space flood zones if adequate flood proofing measures are taken and if it is demonstrated that the measures will not cause additional flooding and/or drainage in other areas. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY F. Require development along creeks to be set back from the entire 100-year floodway of the creek. Require development along Uvas Creek and the main branch of Llagas Creek to be set back from the 100-year floodplain, or 250 feet on either side of the creek centerline, whichever is greater; Require development along tributary creeks to be set back from the entire designated floodway of the creek. Setbacks required should allow adequate room for trails and access on both sides of the creek. Determination of actual layout and size of these creekside linear parks is recommended for further study that could be addressed in a City Parks and Recreation Master Plan. Setback land could be dedicated to the City by the subdivider/developer or the City could purchase an easement over the setback area. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY G. Require easements or setbacks to protect natural drainages as part of the drainage requirements or improvements before approving Tentative Maps for new development. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY I. Revise the City Street Tree Ordinance and Landscape Policy to include specific tree lists and landscape guidelines emphasizing native species for use in special habitat areas; i.e., riparian corridors and hillside areas. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY L. Work with the Flood Control District in restoring native riparian vegetation along the West Branch of Llagas Creek in the event the channel is excavated for flood control purposes. CONSERVATION AND OPEN SPACE, IMPLEMENTATION POLICY N. Amend the City's grading ordinance to require measures to prevent slope destabilization or erosion, including revegetation, protection of bare soil until vegetation is well established, and slope stabilization structures. PARKS AND RECREATION ELEMENT, POLICY 15. The City should attempt to acquire the rights to use public and quasi-public utility and drainage channel corridors as linear parks to provide the network for a system of pedestrian and bicycle paths. Whenever feasible, recreational open spaces and linear parks should be linked to each other and to those planned by the Santa Clara County Parks and Recreation Department. Where interruption of the open space network is unavoidable, connecting foot and bicycle paths should be marked and made as safe as possible. PARKS AND RECREATION, IMPLEMENTATION POLICY C. Work closely with Santa Clara County, Santa Clara Valley Water District, the utility companies and other agencies in developing a bike and pedestrian path system separated from auto traffic to provide both a pleasant means of recreation and transportation. Public and quasi-public utility and flood control channel corridors furnish an excellent opportunity for linking open space and park activity areas, schools, shopping areas, and residential neighborhoods in the Gilroy Planning Area. The Ronan Channel easement and creekside easements along the Uvas and both branches of the Llagas Creeks should be utilized for this purpose. PARKS AND RECREATION, IMPLEMENTATION POLICY D. Of the proposed recreational facilities on the General Plan map, give first priority to the development of the Uvas Creek Linear Park because of its integral and strategic location with the urbanized area. Develop Uvas Park Drive as a two-lane recreational road which will accent the Uvas natural area. Provide pedestrian and bicycle trails within the linear park and limited parking turn-out areas along the Uvas Park Drive right-of-way. PUBLIC SAFETY AND SEISMIC SAFETY, IMPLEMENTATION POLICY W. The City will work with the Water District to actively pursue funding for the Llagas Creek Watershed Project or a project of similar magnitude as a comprehensive means of alleviating flooding and drainage problems in the Planning Area. In the event federal funding for this project is unavailable, the City will work with the district and affected property owners to provide local measures including the possible formation of a special assessment district to fund these improvements. PUBLIC SAFETY AND SEISMIC SAFETY, IMPLEMENTATION POLICY Y. Restrict development in those areas subject to major sheet flooding in the northern portion of the Planning Area until adequate drainage improvements are provided. PUBLIC SAFETY AND SEISMIC SAFETY, IMPLEMENTATION POLICY Z. Restrict areas subject to both flooding and saturated soil conditions in the vicinity of Miller Slough and Llagas Creek east of the freeway to agriculture and recreational use. PUBLIC SAFETY AND SEISMIC SAFETY, IMPLEMENTATION POLICY AA. Actively enforce the Flood Plain Management ordinance to prevent further encroachment of development in floodways and assure compliance with Federal Flood Insurance regulations. Relevance to the Proposed Program: Gilroy is one of the few cities within District boundaries which has not been completely developed, therefore offering opportunities for insightful land use planning that incorporate the natural hydrological and geomorphic riverine processes and hopefully can minimize the need for future intensive, engineered flood protection which generates a long-term maintenance requirement. e. City of Los Altos The City of Los Altos has goals in the Natural Environment and Hazards General Plan element that pertain to lands that are under the District's jurisdiction. Goals and Policies include: 1) Policies particularly relevant to District activities NATURAL ENVIRONMENT AND HAZARDS, POLICY 8. The City shall continue to discourage concrete lining of creek beds, and shall encourage the Santa Clara Valley Water District to use environmentally sensitive solutions to control local erosion problems. Consistency: The District will assist the City of Los Altos in this goal by applying the most appropriate erosion repair method as described in the resource protection policy listed in the SMP and the BMPs listed in this document. NATURAL ENVIRONMENT AND HAZARDS, PROGRAM 11. Encourage the Santa Clara Valley Water District to regularly maintain creek banks, clear drainage channels of silt and debris, and to minimize disruption to riparian habitat in an environmentally sensitive manner. NATURAL ENVIRONMENT AND HAZARDS, PROGRAM 12. Analyze bridge structures for constrictions that cause siltation or erosion. Consistency: The proposed Program would regularly maintain creek banks to carry flood flows and inspect bridges for obstructions that impede flow and for causes of siltation or erosion. The District will assist the City to minimize disruption to riparian habitat by using the BMPs. 2) Other policies relevant to waterways NATURAL ENVIRONMENT AND HAZARDS, POLICY 6. The City shall work with other jurisdictions to regulate land uses in flood-prone areas and should allow development in those areas only with appropriate mitigation. NATURAL ENVIRONMENT AND HAZARDS, POLICY 7. The City shall identify and seek sources of funding to be used toward the prevention of flooding. NATURAL ENVIRONMENT AND HAZARDS, PROGRAM 10. Annually review areas identified on the Development Constraints Diagram as subject to flooding. NATURAL ENVIRONMENT AND HAZARDS, PROGRAM 13. Enforcing measures to reduce soil erosion and volume and velocity of surface runoff from construction sites and large parking lots or other impermeable surfaces. Work with other jurisdictions to ensure that development along creeks will not cause erosion that will affect Los Altos. Relevance to the Proposed Program: The FEMA maps discussed in the General Plan are the basis for the flood constraints shown on the Development Constraints Diagram (Los Altos General Plan, p. 136). All of the above mentioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. The proposed program supports the above goals by maintaining the creeks to the standards of the maintenance guidelines, by applying BMPs and resource protection policies. f. Town of Los Altos Hills The Town of Los Altos Hills has objectives and principles in the Open Space and Conservation General Plan elements that pertain to lands that are under the District's jurisdiction. These include: 1) Policy particularly relevant to District activities OPEN SPACE ELEMENT, PRINCIPLE 1. The major drainage courses should be kept in a natural condition insofar as possible because of their importance in supplying major vegetation, land forms and wildlife habitat, and storm drainage. Consistency:. The District supports the above policy by application of BMPs, resource protection policies, and the use of the softest method appropriate to a site. 2) Other policies relevant to waterways Implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. The Town's Municipal Code, Chapter 7-5 identifies flood damage prevention and referenced FEMA's requirements (Curtis Williams, Planning Director, personal communication). Implementation methods include: CONSERVATION ELEMENT, OBJECTIVE 2. Open Space Conservation Areas. These are portions of other use areas (e.g. residential and institutional) where structures should not be permitted. Generally, these are steep canyons associated with major creeks or their tributaries (i.e. Matadero, Purissima, Adobe, Hale and Permanente Creeks), with heavy vegetation cover where, for reasons of conservation of resources, public welfare and visual amenity uses should be limited to low intensity recreational uses. In addition, visually important open spaces helping to define the community character associated with major religious and education institutional facilities, or with Stanford Industrial Park, are designated open space conservation areas. CONSERVATION ELEMENT, OBJECTIVE 2, IMPLEMENTATION. It is proposed that these areas be preserved through careful regulation of development combined with conservation easements. An alternative to public ownership of conservation easements may be ownership by neighborhood residents with use limited to low intensity private recreational activities. Many of the stream canyons, however, are essential as links in the Town's public trails and paths system. CONSERVATION ELEMENT, PRINCIPLE 2. In the planning, environmental impact review, and completion of all land development or land alteration projects, particular attention should be directed toward protection of the natural water regimen. CONSERVATION ELEMENT, PRINCIPLE 4. An overriding consideration in the design of any land development project should be conservation of the natural slope and preserving existing native vegetation, and conservation of natural drainage channels and swales since they serve in place of artificial storm drainage systems. CONSERVATION ELEMENT, PRINCIPLE 9. Those areas rich in wildlife or of a fragile ecological nature (e.g., areas of rare or endangered species of plants, riparian areas, etc.), should be avoided in land development. Where necessary, these areas should be publicly acquired to ensure their protection. CONSERVATION ELEMENT, PRINCIPLE 10. The use of pesticides should be strictly controlled to ensure that deleterious materials will not find their way into local streams or cause other forms of contamination. OPEN SPACE ELEMENT, OBJECTIVE 2. To protect and maintain those areas necessary to the integrity of natural resources and processes with special emphasis on, but not limited to, the water regime, open spaces vital for wildlife habitat, and other areas of major or unique ecological significance. OPEN SPACE ELEMENT, OBJECTIVE 3. To preserve open space for the managed production of resources that are suitable in Los Altos Hills, such as agriculture and the maintenance of groundwater supplies. OPEN SPACE ELEMENT, PRINCIPLE 9. Unstable terrain, active fault traces, water channels, flood plains, and other areas determined hazardous to public welfare and safety or necessary for storm drainage should be kept as open space unless unobtrusive corrective measures can assure public safety and meet public need. OPEN SPACE ELEMENT, PRINCIPLE 10. Conservation easements, open space zoning, and other land use regulations should be used to prohibit development on unstable terrain, active fault traces, water channels, flood plains, excessively steep slopes and other areas determined hazardous to public welfare and safety. OPEN SPACE ELEMENT, IMPLEMENTATION 1. The zoning, subdivision, and site development ordinances should be amended to help provide for implementation of the open space conservation area concept. OPEN SPACE ELEMENT, IMPLEMENTATION 2. The zoning ordinance should be amended to establish an open space zoning district which will carry out the intent of the open space preserve land use category in the General Plan. Relevance to the Proposed Program: All of the above mentioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development within the Town would not result in an increase of future routine maintenance activities performed by the District. g. Town of Los Gatos The Town of Los Gatos has policies in the Open Space and Natural Resources and Safety General Plan elements that pertain to lands that are under the District's jurisdiction. Policies include: 1) Policies particularly relevant to District activities NATURAL RESOURCES, IMPLEMENTATION, 2D. Land surrounding reservoirs and streams should be improved by the addition of trees and shrubs, especially adjacent to areas where banks or channels have been modified for flood protection. Consistency: The Program contemplates work within the town of Los Gatos, within San Tomas Aquino and Los Gatos Creeks. San Tomas Aquino and Los Gatos Creeks would all be potential opportunities for biotechnical repair or alternative bank protection solutions (see the discussion under Biology). The District will assist the Town of Los Gatos in this goal by applying Best Management Practices (BMPs), resource protection, and the most appropriate erosion repair method as described in the SMP. 2) Other Policies Relevant to Waterways NATURAL RESOURCES, POLICY 2A. Apply land use regulations, scenic easements, or other appropriate measures to keep a maximum of the watershed and lands immediately contiguous to reservoirs and stream channels in an open natural state. NATURAL RESOURCES, POLICY 2C. Require Environmental Impact Reports for development on riparian lands, hillside areas and important undeveloped watershed areas that consider the single and cumulative impacts on water drainage and contamination . NATURAL RESOURCES, POLICY 2D. Establish open space and recreation as the priority use for lands immediately adjacent to reservoirs and streams. NATURAL RESOURCES, POLICY 2E. Delineate and adopt designated floodways for all major streams utilizing the full flood plain concept as a first priority and the modified flood plain concept as a second priority for flood plain development. NATURAL RESOURCES, IMPLEMENTATION, 2A. All development of riparian lands and undeveloped watershed areas shall include detailed evaluations of the individual and cumulative impacts on water drainage and contamination. NATURAL RESOURCES, IMPLEMENTATION, 2B. Development plans shall be prepared for Los Gatos and Guadalupe Creeks which include: a) the use of flood-prone areas as open space; b) redevelopment including recontouring and landscaping where the natural environment has been altered by channelization; and c) paths for bicyclists or hikers. NATURAL RESOURCES, IMPLEMENTATION, 2C. Planning efforts should be coordinated with the Santa Clara Valley Water District. NATURAL RESOURCES, IMPLEMENTATION, 2E. Flood plain zoning shall be adopted to prevent inappropriate development in areas subject to flooding. OPEN SPACE, POLICY 7. Promote a system of Town parks and maximize the use of public utility easements, flood control channels, school grounds, and other quasi-public areas for recreational uses. OPEN SPACE, POLICY 9. Encourage the retention of stream bed corridors in their natural settings and utilize them wherever possible for paths and trails. OPEN SPACE, POLICY 16. Consider effects on watershed areas before allowing development of any open space. OPEN SPACE, IMPLEMENTATION POLICIES 2A AND 2B. Guidelines shall be established for developmental review that protect wildlife habitat and natural watershed lands . SAFETY IMPLEMENTATION, 2A. Limit the intensity of land use in flood plain areas. SAFETY IMPLEMENTATION, 2B. Require site planning and building design to address identified flood hazards. SAFETY IMPLEMENTATION, 2C. Insure federal standards are met for development in designated flood plains along Los Gatos Creek and other creeks. Relevance to the Proposed Program: All of the above mentioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development would not result in an increase of future routine maintenance activities performed by the District. h. City of Milpitas The City of Milpitas adopted a Floodplain Management Plan in 1991 which has policies and goals intended to reduce damage within flood-prone areas in the City. These policies specifically address damage reduction techniques such as construction of storm drainage pump stations, force mains and related work; more intense maintenance of the city's drainage systems; supporting major flood protection improvements by the District (and others); and maintaining and updating the City's Flood Warning Program. The Sandy Wool Lake Dam is not part of the District's facilities. The City of Milpitas has guiding principles and implementing policies in the Open Space/Conservation and the Seismic and Safety General Plan elements that pertain to lands that are under the District's jurisdiction. In addition, the General Plan identifies participation in the National Flood Insurance Program. Principles and Implementing Policies include: 1) Policies particularly relevant to District activities DRAINAGE AND FLOODING, GUIDING PRINCIPLE, 5.B-G-1. Minimize threat to life and property from flooding and dam inundation. Consistency: By providing routine maintenance activities to creeks within the City of Milpitas, the District will assist the City in minimizing the threat to life and property from flooding. 2) Other policies relevant to waterways BIOTIC RESOURCES, GUIDING PRINCIPLES, 4.B-G-1. Protect and conserve open spaces which are necessary for wildlife habitats and unique ecological patterns. BIOTIC RESOURCES, IMPLEMENTING POLICIES, 4.B-I-1. Strictly enforce grading regulations controlling removal of vegetative cover from hillside areas. DRAINAGE AND FLOODING, IMPLEMENTING POLICY, 5.B-I-1. Ensure that new construction or substantial improvements to any existing structure result in adequate protection from flood hazards. This includes ensuring that: New residential development within the 100-year Flood Zone locate the lowest floor, including basement, above the base flood elevation; and New non-residential development locate the lowest floor, including basement, above the base flood elevation or incorporate flood-proofing and structural requirements as spelled out in the Municipal Code. DRAINAGE AND FLOODING, IMPLEMENTING POLICY, 5.B-I-2. Require all structures located within the 100-year Flood Zone to provide proof of flood insurance at the time of sale or transfer of title. DRAINAGE AND FLOODING, IMPLEMENTING POLICY, 5.B-I-3. Ensure that encroachment into designated floodways does not result in any increase in flooding hazards . DRAINAGE AND FLOODING, IMPLEMENTING POLICY, 5.B-I-4. Continue working with the Office of Emergency Services to update and maintain the Sandy Wool Lake Dam failure evacuation plan. DRAINAGE AND FLOODING, IMPLEMENTING POLICY, 5.B-I-5. Seek construction of flood control channels to withstand 100-year floods along Coyote, Penitencia, Berryessa, Scott, Calera, and Los Coches Creeks. OPEN SPACE/CONSERVATION PRINCIPLE 4.A-G-2. Develop a diversified trail system along streamsides and other public rights of way to provide recreational opportunities and link facilities. OPEN SPACE/CONSERVATION PRINCIPLE 4.A-I-5. Provide an extensive, visually stimulating system of "people paths" by developing park chains along Coyote River and the Hetch Hetchy right-of-way. OPEN SPACE/CONSERVATION PRINCIPLE 4.A-I-6. Develop the Coyote River area in cooperation with the County Park and Recreation Commission in a linear park chain that would connect with the Coyote Park Chain in San Jose and provide a safe mechanism for undertaking flood-control measures. The trails along Coyote Creek should be part of the San Francisco Bay Trail, a regional network of trials used by hikers and bicyclists. Relevance to the Proposed Program: All of the above mentioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development would not result in an increase of future routine maintenance activities performed by the District. i. City of Monte Sereno The City of Monte Sereno has no policies directly relevant to District activities. The City has guiding principles and implementing measures in the Land Use, Open Space and Conservation, Public Services and the Safety General Plan elements that pertain to lands that are under the District's jurisdiction. Three creeks flow through the city: San Tomas Aquino, Almendra and Daves Creeks. Daves Creek has been piped to the maximum extent possible while San Tomas Aquino and Almendra Creeks have been left in their natural state. Current city regulations limit development in the flood plains of these creeks (Monte Sereno General Plan, Open Space and Conservation Element, p. 3.) Standards and implementation measures include: LAND USE ELEMENT, IMPLEMENTATION MEASURE L3. Establish and define a conservation zone for the City within which the environment is to have a greater priority than man's utility. Revise Urban Service Areas so that only areas that are served by proper and adequate roads, utilities and sewerage, and the new boundary will be logical in terms of the provision of municipal services including police, fire, road and storm drain maintenance, are retained as designated Urban Service Areas. OPEN SPACE AND CONSERVATION ELEMENT, STANDARDS, PAGE 4. Creeks shall be maintained in as close to natural condition as public safety permits. New structures shall be set back a minimum of 20 feet from 100-year flood influence line. OPEN SPACE AND CONSERVATION ELEMENT, STANDARDS, PAGE 4. Impervious coverage limits included in the Land Use Element should be adopted to allow ground water development and to prevent excessively rapid and potentially damaging runoff. Two small areas of Monte Sereno near San Tomas Aquino Creek totaling less than 5 acres are subject to flooding from the 1 percent event. The overwhelming majority of homes in these areas are constructed above the base flood elevation. Recognizing the minimal danger of flooding, the Federal Emergency Management Agency has withdrawn the city from the emergency program of the National Flood Insurance Program. Severe, large scale flooding does not occur in the City based upon Federal Flood Insurance Maps that are adopted as part of this plan (Monte Sereno General Plan, Safety Element, page 2). Relevance to the Proposed Program: All of the above mentioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development would not result in an increase of future routine maintenance activities performed by the District. j. City of Morgan Hill The City of Morgan Hill has policies in the Open Space and Conservation Element, and Environmental Safety General Plan elements that pertain to lands that are under the District's jurisdiction. These policies include: 1) Policies particularly relevant to District activities OPEN SPACE AND CONSERVATION, POLICY 4C. Where flood control projects are needed to protect existing development, minimize disruption of streams and riparian systems, maintaining slow flow and stable banks through design and other appropriate mitigation measures. Consistency: The District would assist
the city to minimize disruption of streams and riparian systems by following
the BMPs that are part of this document. Maintaining stable banks is
part of the District's Stream Maintenance program. OPEN SPACE AND CONSERVATION ELEMENT, POLICY 5G. Design streamside development in such a way as to facilitate maintenance of the waterway and protection of the environment and riparian areas. OPEN SPACE AND CONSERVATION ELEMENT, POLICY 5G, ACTION ITEM. Give careful consideration to the use of streets to separate urban streamside development from waterways consistent with Santa Clara Valley Water District recommended streamside street designs . Consistency: The use of streets to separate residential lots from waterways to keep development out of the 100-year, unimproved floodway would minimize the District's future responsibility for both sediment removal and bank protection (vegetation management work may continue). The Stream Maintenance Program contemplates sediment removal/vegetation management work in Morgan Hill, which will probably occur on West Little Llagas Creek and Madrone Channel. Substantial portions of the land adjoining these channels is not yet developed and would be amenable to such setbacks from waterways as part of future urban land use planning. For example 85% of the land adjoining Llagas Creek, 50% of the land adjoining West Little Llagas Creek and 90% of the land adjoining the Madrone Channel was designated as natural open space in the ABAG 1995 land use mapping. OPEN SPACE AND CONSERVATION ELEMENT, POLICY 4E. Preserve all riparian habitats as shown on the Habitats Resources map of the Open Space and Conservation Element in their natural state. Consistency: The District's proposed BMPs and mitigation program for the Stream Maintenance Program will assist the City of Morgan Hill with compliance with this policy. 2) Other policies relevant to waterways FLOOD CONTROL, POLICY 5A. Since flooding affects substantial areas of South County, and the flood control projects now being constructed are designed to protect only existing developed and currently planned urban areas, manage land development by the three South County jurisdictions to mitigate flooding problems and to minimize the need for local public funding for additional flood control and local drainage facilities. FLOOD CONTROL, POLICY 5B. Minimize flood damage in South County through a combination of actions. In flood-prone areas, inappropriate development should be prevented through land use planning, urban development policies and land use regulations. Areas that are developed or planned for development should be protected by the construction of flood control facilities. Development should be managed through advanced planning and design standards to minimize off-site flooding and drainage problems. FLOOD CONTROL, POLICY 5C. Give highest priority for construction of flood protection facilities as follows: first, to areas of existing development subject to the highest potential flood damage; second, to undeveloped areas planned for urban development which would be subject to the highest potential of flood damage; then, to agricultural lands; and finally, to other undeveloped areas. FLOOD CONTROL, POLICY 5D. If federal and state funds are not available for future flood control facilities and such facilities must be funded locally, assess the costs to those property owners who would benefit from and those who contribute to the need for such facilities should pay the cost. FLOOD CONTROL, POLICY 5E. Require developers whose proposed projects would induce downstream flooding to provide mitigation to eliminate the flood-inducing impacts of their projects. FLOOD CONTROL, POLICY 5F. If development is to be allowed in flood-prone areas, provide flood control facilities or appropriate flood-proofing prior to or in conjunction with development at developers' expense. FLOOD CONTROL, POLICY 5G. Where other mitigations do not solve the flooding problem, permit raising individual foundations (padding up structures) in appropriate situations. However, padding up must be restricted in order to minimize the cumulative effects on adjacent areas. FLOOD CONTROL, POLICY 5H. Require mitigation of any stormwater runoff produced by development that occurs beyond that described in the General Plans of the County and the Cities as of 1982. FLOOD CONTROL, POLICY 5I. Require all local development to provide appropriate mitigations of off-site flooding and runoff impacts, including: limited runoff to pre-development levels and/or complete solutions to flooding and local drainage problems in the vicinity of the development. Mitigations may include: detention (storing runoff temporarily and then releasing it) or retention (storing runoff on-site for percolation). FLOOD CONTROL, POLICY 5J. Require careful consideration of the cumulative effects of development which would drain into the upper reaches of the Llagas Creek and other creeks in order to avoid the need for channelization and consequent destruction of its riparian vegetation and natural habitat. FLOOD CONTROL, POLICY 5K. Designated floodways should be identified and indicated on the General Plan and Zoning Map. FLOOD CONTROL, POLICY 5L. Flood plain zoning should be applied to designated floodways in order to maximize life safety, reduce property loss, and preserve natural vegetation, wildlife and scenic beauty. FLOOD CONTROL, POLICY 5M. All floodway areas as designated on the Permeability/Flood Boundaries map of the Open Space Conservation Element shall be designated as open space, prohibiting all construction of structures within this floodway. FLOOD CONTROL, POLICY 5M, ACTION ITEM. Send all subdivisions and private and public project referrals where activity is located near to floodplain areas to Santa Clara Valley Water District for review prior to City approval. FLOOD CONTROL, POLICY 5M, ACTION ITEM. Require dedication pursuant to the State Map Act sections 66475 and 66478.5 for access to and along all waterways. FLOOD CONTROL, POLICY 5M, ACTION ITEM. Continue to require dedication of floodway and floodplain areas pursuant to the PL566 Drainage Program. FLOOD CONTROL, POLICY 5N. Regulate all floodplains as designated on the Permeability/Flood Boundaries Map of the Open Space/Conservation Element areas with specific standards minimizing flooding of existing structures and surrounding properties. LAND USE ELEMENT, POLICY 4D. Avoid development in areas of natural hazards such as landslide and flood prone areas (see related policies in Conservation and Environmental Safety Elements). OPEN SPACE AND CONSERVATION, POLICY 1A. The South County includes a variety of open space areas including the valley floor, stream corridors, lands around reservoirs, lands adjacent to scenic highways, the valleys, and the mountain areas beyond the foothills. This variety of open space areas should be preserved and maintained. Greenbelts should delineate and provide contrast to the urban areas of the South County cities. A system of city and regional parks should be created, linked by pedestrian ways, trails and streamside park chains. Implementation of the Llagas and Uvas Creeks as major streamside park chains should be actively promoted. OPEN SPACE AND CONSERVATION, POLICY 1D (C). Continue City programs to implement portions of trail systems and streamside park chains within their boundaries. OPEN SPACE AND CONSERVATION, POLICY 1E. Give highest priority to stream corridors, lands around reservoirs, lands which provide greenbelts for the cities, and significant hillside features for preservation as open space. OPEN SPACE AND CONSERVATION ELEMENT, POLICY 4E, ACTION ITEM A. Require dedication at time of subdivision or improvement of property adjacent to Llagas and Coyote Creeks.
OPEN SPACE AND CONSERVATION ELEMENT, POLICY 4E, ACTION ITEM B. Utilize purchase or dedication of conservation easements along Llagas and Coyote Creeks.
OPEN SPACE AND CONSERVATION ELEMENT, POLICY 4E, ACTION ITEM C. Draft and adopt a Design Ordinance which sets forth creekside and lakeshore design guidelines. Relevance to the Proposed Program All of the abovementioned policies pertain to new development. They are relevant because if implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development would not result in an increase of future routine maintenance activities performed by the District. k. City of Mountain View The City of Mountain View has policies in the Community Development and Environmental Management General Plan elements that pertain to lands that are under the District's jurisdiction.

Protect and preserve soil as a natural resource. Consistency: The bank stabilization work and the use of BMPs contemplated under the Program will assist the City of Mountain View in meeting this goal. The District's use of biotechnical bank stabilization methods will improve bank habitat in conjunction with its bank protection work. All of the creeks within Mountain View's municipal boundaries or sphere (Adobe, Hale, Permanente, and Stevens Creeks) would be potential candidates for biotechnical or alternative treatments to preserve biological resources. ENVIRONMENTAL MANAGEMENT, POLICY 25. Protect and restore plant and wildlife habitats. ENVIRONMENTAL MANAGEMENT, ACTION 25.B. Use open space zoning districts and capital projects to preserve and enhance creekside habitats . ENVIRONMENTAL MANAGEMENT, GOAL I. Preserve and enhance the diversity of biological resources in Mountain View. Consistency: The City of Mountain View could work directly with the District to combine the City's goal with the District's mitigation objectives according to the District's SMP Policies. 2) Other policies relevant to waterways COMMUNITY DEVELOPMENT, GOAL A. Promote a pattern of land use that protects the community's health and safety. COMMUNITY DEVELOPMENT, GOAL D. Encourage the development that preserves the beauty of the natural environment. COMMUNITY DEVELOPMENT, POLICY 1. Ensure that new development is built and located to minimize the dangers of flooding, airfield effects, earthquake hazards, and hazardous materials. COMMUNITY DEVELOPMENT, POLICY ACTION 11.D. Ensure that common or public outdoor areas are designed to be next to adjoining natural features. ENVIRONMENTAL MANAGEMENT, GOAL B.

Protect designated public open spaces from redevelopment.
ENVIRONMENTAL MANAGEMENT, ACTION 11.C. Use the Flood Plain district to preserve open space lands and to protect people and buildings from flood hazards. Relevance to the Proposed Program: These policies would reflect the City's desire to utilize creeks as an important natural open space amenity in the landscape, both for public enjoyment and resource values. The BMPs built into the proposed Program are to ensure that the District can carry on its maintenance work within the values the City wants to preserve and develop for urban creeks. l. City of Palo Alto The City of Palo Alto has policies in the Community Design and Natural Environment General Plan elements that pertain to lands that are under the District's jurisdiction. Goals, policies and programs that are listed in the 1998-2010 Comprehensive Plan include: 1) Policies particularly relevant to District activities NATURAL ENVIRONMENT, POLICY N-9: Avoid fencing, piping, and channelization of creeks when flood control and public safety can be achieved through measures that preserve the natural environment and habitat of the creek. NATURAL ENVIRONMENT, POLICY N-10. Work with the Santa Clara Valley Water District and other relevant regional agencies to enhance riparian corridors and provide adequate flood control by use of low impact restoration stategies. NATURAL ENVIRONMENT, PROGRAM N-10: Work with the Santa Clara Valley Water District to establish guidelines for creek channel maintenance that encourage preservation of riparian habitat, including vegetation that provides shade to creek bottoms. NATURAL ENVIRONMENT, PROGRAM N-11: Work with the Santa Clara Valley Water District to develop a comprehensive riparian corridor restoration and enhancement program that identifies specific stretches of corridor to be restored, standards to be achieved, and sources of funding. Include provisions for tree planting to enhance natural habitat. NATURAL ENVIRONMENT, POLICY N-13: Discourage creek bank instability, erosion, downstream sedimentation, and flooding by minimizing site disturbance and vegetation removal on or near creeks and carefully reviewing grading and drainage plans for development near creeks and elsewhere in the watersheds of creeks. NATURAL ENVIRONMENT, POLICY N-22: Limit the amount of impervious surface in new development or public improvement projects to reduce urban runoff into storm drains, creeks and San Francisco Bay. Consistency: The proposed Program provides routine maintenance of channels to ensure protection from the flood flows. The proposed Program would assist the city in protecting residents and their property from flood hazards. The District's use of biotechnical bank stabilization methods will improve bank habitat in conjunction with its bank protection work. Implementation of Policy N-22 will assist the District in achieving stated flood protection goals. Application of BMPs and resource protection policies will support the City in its environmental management policies. NATURAL ENVIRONMENT, POLICY N-11: Preserve the integrity of riparian corridors. NATURAL ENVIRONMENT, PROGRAM N-7: Adopt a setback along natural creeks that prohibits the siting of building and other structures, impervious surfaces, outdoor activity areas, and ornamental landscaped areas within 100 feet of the top of a creek bank. Allow passive or intermittent outdoor activities and pedestrian, equestrian, and bicycle pathways where there are adequate setbacks to protect the natural riparian environment. Within the setback areas, provide a border of native riparian vegetation at least 25 feet along the creek bank. NATURAL ENVIRONMENT, PROGRAM N-8: Develop and adopt a creek ordinance that establishes new development regulations for properties abutting creeks, establishes an exception process, and provides incentives to achieve maximum creek setbacks, such as reduced front yard setbacks and reduced on-site parking requirements. Consistency: The Stream Maintenance Program includes provisions to improve fish habitat and increase the amount of shaded riverine habitat. Application of BMPs and resource protection policies will support the City in its environmental management policies. San Francisquito, Adobe, and Stevens Creeks are potential candidates for the biotechnical bank treatment. The policy which pertains to new development is relevant because if implemented, it could limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Effects of future development would not result in an increase of future routine maintenance activities performed by the District. Certain policies also reflect the City's desire to utilize creeks as an important natural open space amenity in the landscape, both for public enjoyment and resource values. The BMPs built into the proposed SMP are to ensure that the District can carry on its maintenance work within the values the City wants to preserve and develop for urban creeks. NATURAL ENVIRONMENT, POLICY N-12: Preserve the habitat value of creek corridors through the preservation of native plants and the replacement of invasive, non-native plants with native plants.
Consistency: The Stream Maintenance Program includes the eradication of invasive and non-native plants and their replacement with native species, wherever practicable. 2) Other policies relevant to waterways Goals, policies, and implementation measures are listed in the General Plan to mitigate for impacts caused by new development upstream and upslope of the channels. These include: NATURAL ENVIRONMENT, PROGRAM N-27: Work with regulatory agencies, environmental groups, affected businesses, and other stakeholders to identify economically viable Best Management Practices (BMPs) for reducing pollution. Participate in BMP pilot studies to identify new pollution control measures. NATURAL ENVIRONMENT, PROGRAM -28: Continue public education programs on water quality issues, including Best Management Practices (BMPs) for residents, businesses, contractors, and City employees. NATURAL ENVIRONMENT, PROGRAM N-29: Actively participate in programs such as the Santa Clara Valley Urban Runoff Pollution Prevention Program to improve the quality of stormwater runoff. NATURAL ENVIRONMENT, PROGRAM N-31: Evaluate spill response, cleanup and follow-up investigation procedures to reduce the impacts of toxic spills on water quality in the City's creeks and San Francisco Bay. COMMUNITY DESIGN, POLICY L-68: Integrate creeks and green spaces with the street and pedestrian/bicycle path system. Relevance to the Proposed Program: The enforcement of this policy by the City will reduce the release or upset of hazardous materials in the creeks and waterways within the District's jurisdiction. Better long-term coordination between the District and other local agencies with regard to issues of mutual concern including watershed and floodplain management, riparian corridor protection and restoration, and the interaction between flood protection, creek maintenance and land use planning would improve the condition of creeks and could reduce the need for the District to perform frequent routine maintenance. m. City of San Jose 1) Policies particularly relevant to District activities HAZARDS, FLOODING, POLICY 4. The City and the Santa Clara Valley Water District should cooperate to develop flood control facilities to protect the Alviso and North San Jose areas from the occurrence of the "1%" or "100-year flood. . HAZARDS, FLOODING, POLICY 5. Appropriate emergency plans for the safe evacuation of occupants of areas subject to possible inundation from dam failure and dam flooding should be prepared and periodically updated. Consistency: The proposed Program provides routine maintenance of channels to ensure protection from flood flows. The proposed Program would assist the city in protecting residents and their properties from flood hazards. HAZARDS, FLOODING, POLICY 8. The City should cooperate with the Santa Clara Valley Water District to develop additional flood control retention facilities in areas where existing retention facilities are nearing capacity. Consistency: Flood protection retention facilities developed in conjunction with new developments may reduce flood intensities and reduce the need for both flood protection improvements and long-term maintenance. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 2. New public and private development adjacent to riparian corridors should be consistent with the provisions of the Riparian Corridor Policy Study. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 3. New development within the Urban Service Area should be set back from the outside edge of riparian habitat (or top of bank, whichever is greater) a distance sufficient to buffer the impacts of adjacent human activities and provide avenues for wildlife dispersal. Consistency: Keeping development setback from the riparian corridor could minimize the District's future need for sediment removal and/or vegetation management and bank stabilization. The Stream Maintenance Program includes provisions to improve fish habitat and increase the amount of shaded riverine habitat. The application of BMPs and resource protection policies will support the city in meeting its Riparian Corridors and Upland Wetlands policies. In addition, vegetation management practices, including revegetation and revegetation maintenance, will enhance wildlife dispersal corridors. RIPARIAN CORRIDORS AND UPLAND WETLANDS GOAL. Preserve, protect and restore riparian corridors and upland wetlands within the City of San Jose's Sphere of Influence. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 1. Creeks and natural riparian corridors and upland wetlands should be preserved whenever possible . RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 4. New development should be designed to protect adjacent riparian corridors from encroachment of lighting, exotic landscaping, noise and toxic substances into the riparian zone. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 5. When disturbance to riparian corridors and upland wetlands cannot be avoided, appropriate measures should be required to restore, or compensate for damage to, the creeks or riparian corridors. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 6. The City encourages appropriate native plant restoration projects along riparian corridors, upland wetlands, and in adjacent upland areas. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 7. The City should consider the preparation of a Riparian Restoration Action Plan to assess riparian conditions and identify potential riparian restoration programs and priorities. RIPARIAN CORRIDORS AND UPLAND WETLANDS POLICY 8. Natural riparian corridors outside the Urban Service Area should be protected from disturbance associated with development (such as structures, roadways, sewage disposal facilities and overhead utility lines, except those required for flood control or bridging) by a minimum 150 foot setback from the top bank line, whenever feasible. Consistency: The Stream Maintenance Program contemplates sediment removal and/or vegetation management work within the municipal boundaries of San Jose. More sediment removal and/or vegetation management and bank protection work is contemplated within the City of San Jose than within any other local jurisdiction in Santa Clara County. NATURAL RESOURCES, NATURAL COMMUNITIES AND WILDLIFE HABITATS, SPECIES OF CONCERN, GOAL. Preserve habitat suitable for Species of Concern, including threatened and endangered species. NATURAL RESOURCES, NATURAL COMMUNITIES AND WILDLIFE HABITATS, SPECIES OF CONCERN, POLICY 1. Consideration should be given to setting aside conservation areas in the Bay and baylands, along riparian corridors, upland wetlands, and hillside areas to protect habitats of unique, threatened and endangered species of plants and animals, and to provide areas for educational and research purposes. NATURAL RESOURCES, NATURAL COMMUNITIES AND WILDLIFE HABITATS, SPECIES OF CONCERN, POLICY 2. Habitat areas that support Species of Concern should be retained to the greatest extent feasible. Consistency: The instream fish habitat enhancement and offstream mitigation sites included in the Stream Maintenance Program will have a net benefit to Species of Concern, including threatened and endangered species. 2) Other policies relevant to waterways HAZARDS, 3. FLOODING, GOAL. Protect the community from the risk of flood damage. HAZARDS, FLOODING, POLICY 1. New development should be designed to provide protection from potential impacts of flooding during the "1%" or "100-year" flood. HAZARDS, FLOODING, POLICY 2. Development in watershed areas should only be allowed when adequate mitigation measures are incorporated into the project design to prevent unnecessary or excessive siltation of flood control ponds and reservoirs. HAZARDS, FLOODING, POLICY 3. Designated floodway areas should be preserved for non-urban uses. HAZARDS, FLOODING, POLICY 6. The City should support State and Federal legislation which provides funding for the construction of flood control improvements in urbanized areas. HAZARDS, FLOODING, POLICY 7. The City should require new urban development to provide adequate flood control retention facilities. NATURAL RESOURCES, WATER RESOURCES GOAL. Protect water resources because they are vital to the ecological and economic health of the region and its residents.
NATURAL RESOURCES, WATER RESOURCES, POLICY 1. The City, in cooperation with the Santa Clara Valley Water District, should restrict, or carefully regulate, public and private development in watershed areas, especially in those necessary for effective stream flow and for the prevention of excessive siltation. NATURAL RESOURCES, WATER RESOURCES, POLICY 2. Water Resources should be utilized in a manner which does not deplete the supply of surface or groundwater, and efforts to conserve and reclaim water supplies, both local and imported, should be encouraged. NATURAL RESOURCES, WATER RESOURCES, POLICY 3. The City should encourage the Santa Clara Valley Water District to restrict public access and recreational uses on land adjacent to rivers, creeks, freshwater wetlands and other significant watercourses when water quality could be degraded. NATURAL RESOURCES, WATER RESOURCES, POLICY 5. The City should protect groundwater recharge areas, particularly creeks and riparian corridors. NATURAL RESOURCES, WATER RESOURCES, POLICY 6. When new development is proposed in areas where storm runoff will be directed into creeks upstream from groundwater recharge facilities, the potential for surface water and groundwater contamination should be assessed and appropriate preventative measures should be recommended. NATURAL RESOURCES, WATER RESOURCES, POLICY 7. The City shall require the proper construction and monitoring of facilities storing hazardous materials in order to prevent contamination of the surface water, groundwater and underlying aquifers. In furtherance of this policy, design standards for such facilities should consider high groundwater tables and/or the potential for freshwater or saltwater flooding. Relevance to the Proposed Program: The majority of these policies pertain to new development. If implemented, these policies would limit soil erosion, volume and velocity of runoff from future development upstream of the channels. Future development would not cause the need for an increase of future routine maintenance activities performed by the District. n. City of Saratoga The City of Saratoga has policies in the Land Use, Open Space, and Safety General Plan elements that pertain to lands that are under the District's jurisdiction. Policies directly relevant to District activities include: 1) Policies particularly relevant to District activities OPEN SPACE GOAL 16. To preserve, protect and maintain riparian habitats and creek corridors. OPEN SPACE GENERAL POLICY 19. The City's creeks shall be preserved and restored where possible, as natural scenic views. OPEN SPACE IMPLEMENTATION PROGRAM Q. The City should work with the Santa Clara Valley Water District, neighboring jurisdictions, other non-neighboring jurisdictions including but not limited to the California Regional Water Control Board for the San Francisco Bay region, the California Department of Fish and Game, the United States Army Corps of Engineers, and landowners, as appropriate, to restore and enhance the creeks and drainageways to serve as wildlife habitats. Consistency: The Stream Maintenance Program contemplates sediment removal and/or vegetation management work and bank protection work on all 7 creeks within Saratoga's municipal boundaries. The mitigation provisions of the Stream Maintenance Program which include BMPs and offsite enhancement of fish habitat and riparian bank vegetation will assist this jurisdiction in meeting its goal. 2) Other policies relevant to waterways NATURAL RESOURCES, POLICY CO.3.5. Watersheds shall be protected by stringent bank protection during development and by minimizing grading to the fullest extent possible. NATURAL RESOURCES, POLICY CO.3.5 IMP. Implementation through grading Ordinance and through building site approval conditions. Coordinate with Evergreen Resource Conservation District. OPEN SPACE GOAL 3. To use open space to protect human life and property from natural hazards such as fire, flood, seismic, and geotechnical hazards. OPEN SPACE GOAL 5. To protect and conserve natural resources including watersheds, water quality, productive agricultural land, native vegetation and wildlife habitat, mineral land, archeological and historic sites, and areas of ecological significance. OPEN SPACE GOAL 27. The City shall not acquire, plan or develop trail easements or public access easements along Wildcat Creek or Saratoga Creek, across single or multi-family land uses as designated in the Saratoga General Plan abutting said creeks, or adjacent to said creeks between the centerline thereof and any single or multi-family designated property. This policy statement shall apply to Saratoga Creek from Prospect Avenue south to Tollgate Road, and to Wildcat Creek from Quito Road south to the Villa Montalvo Arboretum property line, with the exception of the section between Carnelian Glen Drive and Douglass Lane, as shown on the Trail System Map. OPEN SPACE GOAL 33. Creek and Drainageway Conservation Zone is defined to consist of the watercourse or drainageway itself and surrounding banks on both sides, and a strip of land extending laterally outward from the top of both banks. The establishment of this Zone shall incorporate the Santa Clara Valley Water District (SCVWD) Zone for flood control, maintenance and emergency vehicle access, shall be in accordance with the California Regional Water Quality Control Board for San Francisco Bay Region's policies and guidelines, and shall allow for variations depending upon existing land use and parcel size. OPEN SPACE GOAL 34. The City shall establish a Creek and Drainageway Conservation Zone: To protect Saratoga's creeks and drainageways from pollution and erosion. To enhance and protect water quality. To protect adequate debris flow corridors. To preserve the natural character of creek corridors. To restore existing improved or altered creek corridors to their natural state consistent with flood control requirements. To preserve riparian habitat and wildlife corridors. To provide transition areas between inhabited structures and waterways. To protect properties from damage due to stream bank undercutting and flooding. For the preservation of scenic views. OPEN SPACE IMPLEMENTATION PROGRAM R. The City Code should be amended to include specific regulations regarding the limits of creek drainage and conservation zones. OPEN SPACE POLICY 41. Open space, conservation or scenic easements and dedications shall be utilized to preserve open space lands and to protect critical areas in subdivisions. These areas shall include but not be limited to riparian areas, wildlife habitats and areas of mature native vegetation in subdivisions. SAFETY ELEMENT, PAGE 23. Residential development should not be permitted in designated floodplains unless it has been previously approved by the Santa Clara Valley Water District, or only if the structures are adequately protected by raising the first habitable floor at least one foot above the base floodline level. SAFETY ELEMENT, PAGE 23. Uses within the floodplain which do not subject human life to danger, such as orchards or wildlife preserves, can be permitted in the floodplains. SAFETY ELEMENT, PAGE 24. Land development proposals adjacent to a floodplain or a creek must be reviewed by the Santa Clara Valley Water District, which usually requires the dedication of an easement along natural watercourses or channels under its jurisdiction for the purpose of maintaining the channel or for the future construction of channel improvements. The Water District may also recommend other measures for the mitigation of flood hazards, such as grading of the site and elevation of the structure above the anticipated flooding level. A drainage plan is required by the City at the time of preliminary map submittal to ensure that runoff is drained away from structures. The city engineering department has the responsibility for Saratoga's drainage facilities, and operates in conjunction with the Water District when areas of responsibility overlap. The following policies are from the Hillside Specific Plan Amendment which provide policies for development in hillside areas that may be adjacent to or upstream of the channels within the District's jurisdiction. The Specific Plan Amendment was adopted by the City Council on 6/15/94: CONSERVATION, LAND, AIR AND WATER QUALITY POLICY 2. Preserve natural (creekside) vegetation to the greatest extent feasible. ECOLOGY POLICY 4. Minimize disturbance of creek ecosystems by placing riparian areas in open space. ECOLOGY POLICY 6. Propose trails away from creeks. GEOLOGY AND SOILS POLICY 7. The City, Santa Clara Valley Water District, Evergreen Resource Conservation District and Santa Clara County should immediately commence proceedings with the landowners for the stabilization of the abandoned quarry areas on the Paul Masson Vineyard and Cocciardi properties as well as other erosion reduction activities. HYDROLOGY AND FLOODING POLICY 2. City Council, Planning Commission and City Staff should continue all available efforts to secure remedy to flooding and erosion problems along the main Calabazas and in already developed areas. HYDROLOGY AND FLOODING POLICY 4. Continue (and expand to include the Specific Plan Area) pro-rate share fees for drainage, insuring that they are large enough to pay all costs of necessary facilities to eliminate flooding at the 100-year storm level. HYDROLOGY AND FLOODING POLICY 5. Recommend continuing support of long-term study of hydrology of area. HYDROLOGY AND FLOODING ACTION PROGRAM 1. Work with the Santa Clara Valley Water District to develop appropriate procedures for the above policies. SITE GRADING POLICY 5.
