River Wells Project - Project Description ( Updated)
Title: City of Solvang River Wells Project, Revised 09/27/21 Lead Agency/Project Applicant:

City of Solvang

Project Description: The City proposes to install additional wells in the Santa Ynez River and produce the river underflow within its rights under State Water Resources Control Board SWRCB) Diversion Permit 15878. In May 2015 the City submitted two Petitions: 1) Petition for Time Extension, and 2) Petition for Change in Reach of Diversion. On August 7, 2020 the City filed a letter with the State Water Resources Control Board withdrawing its Petition for Extension of Time and modifying its Petition for Change in Reach of Diversion, which the Board acknowledged in its October 2, 2020 order. The City also submitted a revised project description on October 19, 2020. The City is now further revising its Petition for Change in Reach of Diversion and project description in response to comments from, and negotiations with, protesting parties.

As compared to the 2015 Petition for Change, the City is requesting to ultimately reduce its Reach of Diversion and shift it downstream. The City’s requested final Revised Reach of Diversion is to begin at the Alisal Bridge and extend approximately 8,060 feet downstream. However, in the interim, the City will continue to divert water from its existing well 7A above the Alisal Bridge until it and the existing reach of diversion upstream of the Alisal Bridge are abandoned. See attached proposed Revised Reach of Diversion Map. In addition, the City has elected to:
significantly limit its proposed river well production to its historical maximum annual diversion of 1,368 AFY,
limit its production rate to a maximum of 2.84 cfs,
install no more than two new river wells (as opposed to the six proposed in the initial petition), and
locate any new wells 3,500 feet or more downstream of the Alisal Bridge in Site B area evaluated in the 2014 Certified EIR.

See attached proposed Revised River Wells Site Plan. The City is also electing to cease production from Well 3 and Well 7A if flows at the Alisal Bridge (as monitored by the USGS flow gage) drop below 1.5 cfs or if subsurface water flows drop below 360.3 as measured at the Alisal Ranch Well.

Further, the City will not increase the existing production capacity of Well 7A and Well 3 above 200 gpm and 350 gpm, respectively. The City will also abandon its Well 7A and its existing reach of diversion upstream of the Alisal Bridge once the combined production capacity of Well 3 and any new downstream wells is at least 950 gpm or Solvang constructs two new wells in Site B as shown in the attached Revised River Wells Site Plan. The City maintains an easement for Well 5 that was destroyed several years ago) but will not reconstruct this well or use this well site. See attached proposed Revised Reach of Diversion Map.

The City has elected to make these changes to the Project in a good faith effort to resolve the Protesters concerns and minimize possible impacts on Alisal and ID No.1 river wells, but such changes do not constitute an admission by the City to any of the Protesters claims, assertions or arguments.

The significant benefits of the new River Wells are: 1) water produced from the wells is the most cost effective water source available to the City, 2) additional wells will improve the City’s ability to meet fire flow demands and peak demands during the summer, and 3) use of river water will improve water supply reliability by allowing conjunctive use of both local and imported water supplies. The City’s future peak daily demand at Buildout is estimated at 5.19 cfs. The City’s River Wells and other sources of supply would be required to meet this demand.

Based on the Water Master Plan Update (April 2011) and Integrated Water Supply Management Plan (October 2018), the City’s anticipated future water supply by source has been updated and is shown in Table 2 below. As demonstrated below, the long-term average production from the City’s Santa Ynez River Wells is anticipated to be 650 AFY. However the City is requesting a production level of 1,368 because the City’s need for water from the River Wells will vary from year to year depending on availability from other water supply sources and climactic conditions. The requested production level of 1,368 AFY will accommodate these fluctuations and ensure the City has sufficient water supply for existing and future uses. See Water Code Section 106.5 (the City’s water rights “should be protected to the fullest extent necessary for existing and future uses.”) Table 1 - Total Water Production Based on the Master Plan (Updated) Current and Anticipated Future Supply by Source

Notes:
1) Higher production is expected from this source in certain years, while in other years production will be limited based on climatic conditions.
2) Higher amounts could be obtained from this source. However, use is minimized due to the high cost of this source.

Project Location: As described above, the Project consist of two new River Wells and approximately 2,000 feet of 12” diameter waterline. The two proposed River Wells and associated waterlines will be located along the north side of the Santa Ynez River west of the City of Solvang in Site B as described and evaluated in the 2014 Certified EIR and as shown in the attached proposed Revised River Wells Site Plan. The two proposed River Wells and associated waterlines will be located a minimum of 150 feet back from the high water mark of the River. The proposed waterline will extend from the City’s existing water distribution system at the west end of Fjord Drive westerly approximately 2,000 feet to the proposed new River Wells area. The two new 1082

River Wells will be located a minimum of 1,000 feet apart. See attached proposed Revised River Wells Site Plan.

Project Objectives: The primary objectives of this revised River Wells Project remain the same as objectives of the City of Solvang’ s 2011 Water Master Plan Update and 2014 Certified EIR as follows:

1. Ensure a future reliable water supply to meet the projected water demand at City build out as provided for in the General Plan.

2. Provide for a reliable and diversified water supply through the use of multiple sources of supply.

3. Secure adequate water rights to reliably meet the City’s water supply requirements.

4. Provide the needed water supply at a reasonable cost.

5. Avoid impacts either to public trust resources or to other water rights holders.

Background and Comparison with the 2015 Petition for Change: The SWRCB Diversion Permit 15878 was issued to Solvang Municipal Improvement District ( SMID), the City’s predecessor in interest, in 1969. The City’s Diversion Permit 15878 contemplated diversion by SMID of water from the Santa Ynez River up to 5 cubic feet per second (cfs) and up to 3,600 acrefeet per year (AFY). The 2011 Water Master Plan Update identified an average annual diversion rate of up to 5 cfs from the existing and new River Wells - for a total diversion of approximately 1,980 AFY. The City of Solvang Water Master Plan Update (April 2011) provides details on the existing City water system, proposed future upgrades, and new facilities to supply water to the current and future residents and businesses of the City. The City’s Integrated Water Supply Management Plan ( October 2018) provides additional recommendations on water sources and water supply planning.

The City’s existing Reach of Diversion begins at the Alisal Bridge and extends upstream for a distance of approximately 11,321 feet. The City currently has two active river wells, Wells 3 and 7A. Well 3 is located immediately downstream of the Alisal Bridge and Well 7A is located approximately 800 feet upstream of the Alisal Bridge. Well 7A is located approximately 700 feet upstream of Alisal Ranch Well 2, and approximately 3,800 feet downstream of ID1’ s nearest river well. The City’s original Petitions in May 2015 requested an expanded Reach of Diversion that would have added approximately 8,000 feet of reach of diversion downstream of Alisal Bridge to the existing reach of diversion upstream ofthe Alisal Bridge. Under the revised project description, in the interim, the City will continue to divert water from its existing well 7A above the Alisal Bridge until it and the existing reach of diversion upstream of the Alisal Bridge are abandoned.

However, the final Reach of Diversion under the revised project description will be significantly reduced in total linear feet to approximately 8,060 feet downstream and located entirely downstream of the Alisal Bridge.

It should be noted that in the original 2011 Water Master Plan and 2014 Certified EIR, construction of a new water treatment plant was included to treat water produced from City River Wells. It has since been determined that a water treatment plant is not needed. The proposed treatment plant has been deleted from the project description. The proposed well design is unchanged from that presented in the 2014 Certified EIR. The maximum well depth will be approximately 65 feet.

A summary of the differences between the original May 2015 Petitions and Project, and revised Petition and Project is provided in Table 3 below.

Subject: Terrestrial Biological Resources Technical Report for the CEQA Documentation for the Proposed Revisions to the City of Solvang 2011 Master System Plan Update Environmental Impact Review ( EIR)
Introduction
Pax Environmental Inc. (Pax) conducted a terrestrial biological assessment for Meridian Consultants as an update to the prior terrestrial biological information in the City of Solvang’ s (City) Water System Master Plan Update certified EIR. This included a review of the certified EIR and a site visit to provide any significant updates to the environmental conditions and potential impacts of the project (Proposed Revised Project) on terrestrial biological resources. Potential impacts to aquatic resources were not the focus of this report.

Project Description
The City completed a Water System Master Plan Update dated April 2011 to provide details on the existing City water system, proposed future upgrades, and new facilities to provide water to the current and future residents and businesses of the City. As part of the Water System Master Plan Update, the City had proposed the installation of six new wells to extract underflow from the Santa Ynez River to at the maximum instantaneous rate (5 cubic feet per second ( cfs)) allowable under its existing water right Permit 15878 by extracting underflow from the Santa Ynez River, and utilization of the river wells in conjunction with the other water supplies available to the City to provide a highly reliable source to the water users within the City’s municipal coverage area during all water year types (herein referred to as the Approved Project). The Approved Project was analyzed in the City’s Master Plan Update certified EIR.

The City now proposes to reduce the number of new wells, installing two new wells instead of six. All proposed well sites are located along the north side of the river between the Alisal Bridge and a point approximately 1.5 miles west of the Alisal Bridge. The proposed well sites located downstream of Alisal Bridge are designated Well Sites A and Well Sites B (see Figure 1), and these sites, while within the 100- year floodplain, are outside and above the ordinary high-water mark of the active river channel. These sites were also contemplated and analyzed in the City of Solvang’ s Master Plan Update certified EIR. 1091
2 The 2 new wells would be within Well Site B and at least 150 feet from any surface water flows in accordance with California Department of Public Health DPH) requirements. Supporting well infrastructure would also be constructed as part of the Proposed Revised Project that would connect the new wells to the City’ s existing water distribution system.

The new wells would connect to a new 12 inch diameter waterline to be constructed from the new wells approximately 2,000 feet length to the City’ s existing water distribution system at the western end of Fjord Drive. The proposed width of the pipeline easement area and associated buffer is 40 feet wide in total a 20 foot easement with a 10 foot buffer on both sides). The Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR. The City would be required to acquire additional easements along the Santa Ynez River for the new wells and associated water lines from owners downstream of Alisal Bridge.

Methods
Pax senior biologist Andy Fredell conducted a reconnaissance level field survey on April 2, 2021. 1the reconnaissance level survey occurred on April 2, 2021, during the blooming period for many plant species, in warm and sunny weather conditions within the footprint and the Project area and was focused on the terrestrial species that were present or have the potential to occur within the Project site. A complete coverage, variable intensity pedestrian survey was performed, and modified to account for differences in terrain, vegetation density, and visibility. All visible fauna and flora observed were recorded and identified to the lowest possible taxon. Survey efforts emphasized the search for any special status species that had documented occurrences in the California Natural Diversity Database CNDDB) and eBird within the vicinity of the Well Sites A and Well Sites B Figure 1) and those species on the United States Fish and Wildlife Service USFWS) species list. The locations of any special status species sighted were georeferenced with a geographic positioning system GPS) receiver. Habitat types occurring in the project area were mapped on aerial photographs, and information on habitat conditions to support special status species was also recorded. The project area was also informally assessed for the presence of potentially jurisdictional water features, including riparian zones, isolated wetlands and vernal pools, and other biologically sensitive aquatic habitats. Vegetation communities assemblages of plant species growing in an area of similar biological and environmental factors) were classified by Vegetation Series distinctive associations of plants, described by dominant species and particular environmental setting) using the California Native Plant Society CNPS) Vegetation Classification system Sawyer and Keeler Wolf, 2009).

Surveys were conducted along the north bank of the Santa Ynez River from Alisal Bridge, westward for approximately 1.5 miles, and within the City’ s Alisal Commons open space, between Alisal Road and the Alisal Glen housing subdivision, extending approximately 1,150 feet north of the Santa Ynez River Figure 1). During the survey’ s habitat types were generally defined and mapped Figures 2 and 3) for the purposes of updating the terrestrial biological analyses presented in the City’ s Master Plan Update certified EIR. The following describes the habitat types found in the two Well Sites and species identified during the surveys.
1 The purpose of reconnaissance level surveys is to identify the plant communities within a project site, determine whether or not any threatened, endangered, or sensitive plant or wildlife species are present or have potential to occur on site, and determine what additional protocol level surveys, if any, are needed to determine the presence of special status species and the effects of a project on biological resources. The timing or acceptable window is not required for reconnaissance level surveys compared to protocol level surveys. 1092

Results
Vegetation Communities and Wildlife Habitat Types
Coastal sage scrub or California buckwheat
This vegetation type is present in several areas of Well Site ‘A’ (Figure 2). It forms the typical vegetation along alluvial terraces that are infrequently scoured and is dominated by California buckwheat Eriogonum fasciculatum) and California broomsage ( Lepidospartum squamatum). These are largely tolerant of seasonal drought and dry conditions within the floodplain, which prevail for most of the year outside of active flow channels. Other common species seen within this area include Italianstone pine Pinus pinea), fennel (Foeniculum vulgare), coyote bush (Baccharis pilularis), tocalote (Centaurea melitensis), horseweed ( Conyza canadensis), telegraph weed (Heterotheca grandiflora), slender buckwheat ( Eriogonum microthecum), slender oat (Avena barbata), ripgut brome (Bromus diandrus), red broome (Bromus madritensis), and soft chess (Bromus hordeaceus). California buckwheat alliances including Coastal sage scrub have been assigned a sensitivity rank of G5 S5 by California Department of Fish and Wildlife (CDFW).

Non-Native Grassland
Non-native, annual grasses are the dominant species in this community located in the western portion of Well Site ‘B’ (Figure 3). These grasses germinate in the beginning of the rainy season and have completed their lifecycle by the end of the spring or early summer. Many of these grasslands also support native and non-native annual wildflowers and herbs, particularly in years with above-average rainfall. Dominant species observed in this area include slender oat, ripgut brome (B. diandrus), red broome (B. madritensis), and soft chess (B. hordeaceus), and rabbit' s foot grass (Polypogon monspeliensis). These areas have several dirt access roads throughout this area, and it appears to be disturbed regularly.

Active Agriculture
The northern portion of Well Site ‘B’ is currently farmed with annual crops and is periodically cleared of vegetation. South of this area (defined as non-native grassland with fruit trees in Figure 3) are several mature English walnuts which appear to be former orchard trees.

Developed/ Disturbed
Sparsely vegetated or frequently disturbed areas (adjacent to bare ground along roads and throughout much of proposed Well Site ‘B’) support ruderal taxa including Russian thistle (Kali tragus), annual bursage (Ambrosia acanthicarpa), California mugwort ( Artemesia douglasiana), Italian thistle (Carduus pycnocephalus), tocalote (C. melitensis), yellow starthistle (Centaurea solstitialis), horseweed ( C. canadensis), telegraph weed (H. grandiflora), black mustard (Brassica nigra), tree tobacco (Nicotiana glauca), ripgut brome (B. diandrus), and red brome (B. madritensis) ( Figure 3).

Riparian and Wetland Areas
Willow thickets: These areas are closer to the Santa Ynez River channel which appears to have seen heavy flows at some point in the past decade. These areas are very densely vegetated and dominated by willows— chiefly sandbar willow (Salix exigua) and arroyo willow (Salix lasiolepis) with mulefat 1094
Baccharis salicifolia) present within the canopy. Saplings of Southern California black walnut ( Juglans californica), western sycamore ( Platanus racemose), black cottonwood ( Populus trichocarpa), red willow Salix laevigata), and shining willow (Salix lasiandra) were also present. This is a dominant habitat type in Well Site ‘A’ (Figure 2). Arroyo willow thickets are assigned a sensitive ranking of G4 S4 by CDFW.

Black cottonwood forest: These are areas supporting mature trees and large shrubs along the banks of the floodplain, which demarcate the highest elevation of infrequent flooding within the river. Portions of Well Site ‘A’ have this vegetation type (Figure 2). These areas are dominated by black cottonwood and support numerous medium and large trees, including coast live oak (Quercus agrifolia), Southern California black walnut (J. californica), western sycamore ( P. racemose), red willow (S. laevigata), shining willow (S. lasiandra), arroyo willow (S. lasiolepis), and the non-native Canary Island date palm and Peruvian peppertree. Shrubs seen include mulefat (B. salicifolia), California coffeeberry ( Frangula californica), spiny redberry (Rhamnus crocea), and toyon (Heteromeles arbutifolia).

Understory species dominant in this habitat type include poison-oak (Toxidendron diversilobium), fennel F. vulgare), common cocklebur (Xanthium strumarium), salt heliotrope (Heliotropium curassavicum), pipestem clematis ( Clematis lasiantha), dwarf nettle (Urtica urens), and yellow nutsedge ( Cyperus esculentus). Black cottonwood forests have been given a sensitivity ranking of G5 S3 by CDFW.

California bulrush marsh: A large, excavated depression within the sand and gravel mining operation and Well Site ‘B’ supports a well-developed wetland/ pond/ woodland complex edged by willow thickets and black cottonwood forest and supporting a small marsh of California bulrush (Cyperus esculentus) and narrowleaf cattail (Typha angustifolia) ( Figure 3). California bulrush marshes have been given a sensitivity ranking of G5 S4 by CDFW.

Disturbed pond: A second depression, also within Well Site ‘B,’ supports an additional water- filled depression but lacks any appreciable mature vegetation ( Figure 3). Dominant plant species within this area are chiefly ruderal species and include Russian- thistle (K. tragus), cudweed (Gnaphalium sp.), castor-bean (Ricinus communis), white melilot (Melilotus albus), and rabbit' s foot grass (P. monspeliensis).

Wildlife
Reptiles observed on site included Great Basin fence lizard (Sceloporus occidentalis longipes) and California side-blotched lizard (Uta stansburiana elegans) Suitable habitat is present for common amphibian and reptile species in the project area. In addition, there is suitable habitat for sensitive species including California red-legged frog (Rana draytonii), two stripped garter snake (Thamnophis hammondii), and southwestern pond turtle (Actinemys pallida).

The riparian and upland vegetation in this area provide good quality foraging and nesting habitat for a wide variety of bird species. Bird species observed include mallard (Anas platyrhynchos), California scrub-jay (Aphelocoma californica), great egret (Ardea alba), great blue heron (Ardea herodias), oak titmouse (Baeolophus inornatus), red-tailed hawk (Buteo jamaicensis), California quail (Callipepla californica), Anna' s hummingbird ( Calypte anna), American crow (Corvus brachyrhynchos), snowy egret Egretta thula), belted kingfisher ( Megaceryle alcyon), California towhee (Melozone crissalis), hairy woodpecker ( Picoides villosus), spotted towhee (Pipilo maculatus), bushtit (Psaltriparus minimus), black phoebe (Sayornis nigricans), yellow warbler (Setophaga petechia), and California thrasher ( Toxostoma redivivum).

Mammal species observed on site include California ground squirrel (Spermophilus beecheyi) and desert 1095
cottontail ( Sylvilagus audubonii).

Impact Analysis
The significance of impacts to biological resources depends upon the proximity and quality of vegetation communities and wildlife habitats, the presence or absence of special- status species, and the effectiveness of measures implemented to protect these resources from Project-related impacts.

The updated plant and wildlife species database searches identified 30 sensitive plant species and 54 sensitive wildlife species, as listed in Appendix A, have the potential to utilize the project site or off-site areas affected by project construction and operation. The 2012 certified database searches identified 30 sensitive plant species and 20 sensitive wildlife species. Two species that occurred in the 2012 certified database searches that did not show up in the updated database searches were round leaf filaree California macrophylla, CNPS 1B.1) and dwarf calycadenia ( Calycadenia villosa, CNPS 1B.1). Even though these species did not show up it is not significant because the previous database searches found occurrences of these species far away from the Project area and their habitat requirements are not present at the Project area. The additional plant and wildlife species that were identified in the updated database searches were determined not to occur within the Project area due to the absence of the species during the field survey; lack of suitable habitat; beyond known elevation range; beyond known geographic range; and marginally suitable habitat or outside the terrestrial areas of the Project.

Appendix A includes the details of sensitivity status, habitat requirements and potential for these species to occur. As such, wildlife species were determined to not occur within the Project area, although listed in Appendix A, are not analyzed in this report because no direct, indirect, or cumulative impacts are expected in the terrestrial areas of the Project. In addition, many special-status wildlife species that occur in the area are avian species that may occasionally fly over or forage over the site, but that are not expected to occur during the portion of their life cycle for which their special- status is designated ( usually breeding). Therefore, no impacts would occur to these species. In addition to those identified within the Project site during the site visit, twenty other special- status plant and animal species identified in the CNDDB search have potential to occur based on habitat, including soils, vegetation, and elevation, and the known range of the species.

Potential Direct / Indirect Adverse Effects Upon Special- status Species One special status plant species, Southern California black walnut (J. californica, CNPS 4.2) was detected in several locations in the Project area during the survey, as well as detected during the Certified EIR survey period. Based on a review of the CNDDB database and the habitat types there are six other special- status plant species with the potential to occur including Hoover’ s bent grass (Agrostis hooveri), Santa Ynez groundstar ( Ancistrocarphus keilii), mesa horkelia (Horkelia cuneata var. puberula), Santa Barbara Honeysuckle ( Lonicera subspicata var. subspicata), chaparral ragwort (Senecio aphanactis), and Sonoran maiden’ s hair fern (Thelypteris puberula var. sonorensis). These species have varying degrees of sensitivity identified by CDFW, CNPS, and USFWS listed in Appendix A. In addition, all special- status plant species with a rank of CNPS 1 and 2 identified in the 9-quadrant CNDDB search are listed in Appendix A. The Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR (Well Sites A and B) and would reduce the number of proposed wells from six to two all within Well Site B. Accordingly, the Proposed Revised Project’ s construction- and operation- related impacts on sensitive plant species would be similar to the identified impacts in the Certified EIR. As such, Mitigation measures TER-2 through TER- 8 described in the Certified EIR and listed in Appendix B 1096
would remain applicable to the Proposed Revised Project and would be sufficient to minimize potential impacts to sensitive plant species.

Four special- status animal species were detected in the Project area during the survey including great egret (A. alba), great blue heron (A. herodias), oak titmouse (B. inornatus), snowy egret (E. thula), and yellow warbler (S. petechia). These species were also previously detected in the Project area during the Certified EIR survey period. Based on a review of the CNDDB and eBird databases and the habitat types there are 14 other special status animal species with the potential to occur in the Project area including Southern California steelhead ( Oncorhynchus mykiss irideus), California red-legged frog (Rana draytonii), Coast Range newt (Taricha torosa), California legless lizard (Anniella pulchra pulchra), southwestern pond turtle (Actinemys pallida), two-stripped garter snake (Thamnophis hammondii) Cooper’ s hawk Accipiter cooperii), golden eagle (Aquila chrysaetos), Southern California rufous-crowned sparrow Aimophila ruficeps canescens), ferruginous hawk (Buteo regalis), southwestern willow flycatcher Empidonax traillii extimus, discussed below), least Bell’s vireo (Vireo bellii pusillus, discussed below), pallid bat (Antrozous pallidus), and American badger (Taxidea taxus). These species have varying sensitivities recognized by CDFW and USFWS identified in Appendix A. In addition, all special- status animals identified in the 9-quadrant CNDDB search are listed in Appendix A. The Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR ( Well Sites A and B) and would reduce the number of proposed wells from six to two all within Well Site B. Accordingly, the Proposed Revised Project’ s construction- and operation- related impacts on sensitive animal species would be similar to the identified impacts in the Certified EIR. As such, Mitigation measures TER-1 through TER-7 and TER-9 described in the certified EIR and listed in Appendix B would remain applicable to the Proposed Revised Project and would be sufficient to minimize impacts to sensitive animal species.

Southwestern willow flycatcher (E. traillii extimus) and least Bell’s vireo (V. bellii pusllus) are not expected to nest onsite because the existing riparian habitat vegetation located in a small band along the river and a small remanent in the proposed Well Site B are not extensive enough to support breeding habitat for these species. More extensive riparian habitat which is more suitable for these species does occur approximately 1.3 miles downstream from Well Site B, which is well outside the Project area that this Terrestrial Biological Resources Technical Report and survey focused on. Transient and foraging individuals may utilize the Project area, however given the minimal amount of potential habitat that may exist, this is unlikely. The certified EIR identified suitable Southwestern willow flycatcher habitat approximately 1.3 miles downstream from Alisal Bridge. Typically, flycatchers choose sites in dense riparian vegetation next to the Santa Ynez River channel. Flycatchers breeding on the river often choose sites with standing water or moist surface soils away from the main channel. If water extraction activities at the two new wells were to result in downstream fluctuations in water levels further downstream, they would have the potential to adversely affect southwestern willow flycatcher nesting. However, the certified EIR stated extraction of up to 1,980 acre-feet per year (AFY) would not be expected to cause effects to stream flow (other than potential localized effects 2) and would be 2 The certified EIR calculated drawdown due to the proposed pumping of 2,400 AFY from the proposed Well Sites A and B at various times, distances, and directions. The calculated drawdowns toward the northern alluvial boundary range from a maximum of approximately 9 feet at a distance of 1,000 feet to approximately 7 feet at a distance of 3,000 feet from the proposed well fields in September. This calculation is based on no river or other inflows to the area. The certified EIR stated the proposed Master Plan Update would result in lower drawdown of groundwater 1097
within historical groundwater level fluctuations. The Proposed Revised Project would reduce the planned maximum annual pumping volume from 1,980 AFY in the certified EIR to 1,368 AFY and reduces the planned instantaneous pumping rate from 5 to 2.84 cubic feet per second ( cfs) all of which are within the historic groundwater level fluctuation. Therefore, indirect impacts to Southwestern willow flycatcher (E. traillii extimus) breeding populations 3 due to flow reductions downstream as a result of the Proposed Revised Project are highly unlikely.

Least Bell’ s vireo uses a variety of riparian habitat types with dense understory growth. The certified EIR identified suitable habitat for the least Bell’s vireo occurs in some locations along the Santa Ynez River from Alisal Bridge to Highway 101 and further downstream at Gardner Ranch. Similar to southwestern willow flycatcher, water extraction activities could cause fluctuation in downstream water level, which would have the potential to adversely affect Least Bell’s vireo nesting, if the species were to occupy those resources in the future. However, the certified EIR stated the extraction of up to 1,980 AFY at an increased rate of 5 cfs from the baseline condition of 1,053 AFY and a rate of 1.85 cfs, an increase of 927 AFY and 3.15 cfs, would cause only localized effects to stream flow which is within historical groundwater level fluctuations. As the Proposed Revised Project would reduce the extraction to 1,368 AFY and reduces the planned instantaneous pumping rate from 5 to 2.84 cfs compared to the project in analyzed in the certified EIR, indirect impacts to least Bell’ s vireo due to flow reductions downstream as a result of the Proposed Revised Project are unlikely.

Potential Direct / Indirect Adverse Effects Upon Special- status Habitats or Natural Communities or Corridors
The Certified EIR determined the 1,980 AFY of diversion would not alter the discharge requirements set forth by Order WR 94-5 issued by the State Water Resources Control Board (SWRCB). Order WR 94-5 requires the United States Bureau of Reclamation ( Reclamation) to make releases at Bradbury Dam to ensure the long-term survival of steelhead and other fisheries resources within the Santa Ynez River through implementation of the requirements in the 2000 Biological Opinion (BO) for operation and maintenance of Bradbury Dam. As these resources are dependent on current water releases that also dictate the extent of riparian and floodway resources under the jurisdiction of CDFG and USACE, the Certified EIR determined Reclamation will continue releases to downstream of the project area will remain at present levels. For upland species that may utilize the Santa Ynez River as a source of water or foraging opportunity, the Certified EIR found the installation of wells is not expected to pose an insurmountable obstacle to transverse movements across the river floodplain. Therefore, the Certified EIR concluded no impact to wildlife movement is anticipated and impacts would be less than significant.

SWRCB Order 2019-0148, issued on September 24, 2019, requires Reclamation to release sufficient water from Bradbury Dam to satisfy downstream water rights and to meet flow requirements for the protection of steelhead and their habitat including the flow requirements set forth by the 2000 BO, plus additional flow in wet and above-normal years. Order 2019-0148 discusses potential effects of surcharging Cachuma Reservoir to oak trees and oak woodlands at the margins of the reservoir, however other terrestrial plant resources and terrestrial animal species downstream of Bradbury Dam are not levels as the City would divert 1,980 AFY, 420 AFY less than the 2,400 AFY used to model potential impacts. Even the extreme case represented by the modeling indicates that the impacts would be less than significant due to the depth of the alluvium downstream of Alisal Bridge.
3 Documented approximately three miles southwest of Buellton (from the certified EIR) 1098
discussed.

As discussed in the Results section, Black cottonwood forests were identified within the Project area.

Black cottonwood forests support numerous medium and large trees, including coast live oak (Quercus agrifolia). The Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR ( Well Sites A and B) and would reduce the number of proposed wells from six to two all within Well Site B. As such, similar to the project analyzed in the Certified EIR, even with the releases required by Reclamation in Order 2019-0148, implementation of the Proposed Revised Project would not interfere substantially with the movement of any terrestrial wildlife species or with established native resident or migratory wildlife corridors or impede the use of native wildlife nursery sites.

The Conservation and Open Space Element for the City and the Santa Ynez Valley Community Plan for the County contain provisions for protection of the Santa Ynez River and biological resources. The Certified EIR stated resources and species that are dependent on current water releases, would not experience impact because Reclamation will continue water releases to downstream of the project area as required by Order WR 94-5. Impacts were found to be less than significant. As the Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR and would reduce the number of proposed wells, implementation of the Proposed Revised Project does not conflict with any county or municipal policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.

As discussed in the Results section, above, several sensitive vegetation communities were identified.

Coastal sage scrub or California buckwheat vegetation community, dominated by California buckwheat Eriogonum fasciculatum) and California broomsage ( Lepidospartum squamatum) are in several areas of Well Site ‘A’ and assigned a sensitivity rank of G5 S5 by California Department of Fish and Wildlife (CDFW).

The Results section also identified riparian and wetland areas including Arroyo willow thickets, Black cottonwood forests, and California bulbrush marshes, which are assigned a sensitive ranking of G4 S4, G5 S3, and G5 S4 respectively by CDFW, within the Project area. The Proposed Revised Project components would occur within the analyzed footprint of the Certified EIR (Well Sites A and B) and would reduce the number of proposed wells from six to two all within Well Site B. Accordingly, the Proposed Revised Project’ s construction- and operation- related impacts on sensitive vegetation communities would be similar to the identified impacts in the Certified EIR. As such, implementation of mitigation measures TER10 and TER-11 described in the certified EIR and listed in Appendix B would remain applicable to the Proposed Revised Project and would restore habitat functions and values, thereby reducing direct impacts to riparian habitats and other sensitive natural communities to a level of less than significant.

Additionally, the implementation of mitigation measure TER-12 would ensure habitat enhancement and restoration would occur within Well Site ‘B’ prior to construction of the proposed wells associated with the Proposed Revised Project.

Potential Direct / Indirect Adverse Effects on Nesting Birds The general project area surveyed contains suitable nesting habitat for various bird species. However, no nests or nesting activity was observed in the Project area during the field survey. Riparian corridors are focal areas for birds. Riparian habitat is present within the project area. If active nests are present in the project area prior to construction of the project, implementation of mitigation measure TER-13 described in the certified EIR and listed in Appendix B would remain applicable to the Proposed Revised Project and would be sufficient to minimize impacts to nesting birds in the Project area. 1099
Conclusion/ Recommendations
Vegetation communities and wildlife documented during the survey were nearly identical to those described in the certified EIR. No significant impacts to biological resources that were previously identified in the City’s certified EIR and in this report would result from implementation of the Proposed Revised Project. Portions of the Proposed Revised Project would take place in areas that are currently developed or disturbed by mining, agricultural, or residential uses.

Mitigation measures adopted in the certified EIR and included in the Mitigation and Monitoring Program shall be implemented for special- status species and sensitive vegetation communities ( TER-1 through TER12; see Appendix B). In addition, if construction takes place during January through September, mitigation measures for nesting birds (TER 13; see Appendix B) shall be implemented. No new mitigation measures or protocol level surveys are recommended based on these biological surveys. 1100

Appendix B
Certified EIR Mitigation Measures
1115
The certified EIR identified mitigation measures to address impacts to terrestrial biology. The measures, listed below, would continue to apply to the Proposed Revised Project.

TER-1 Prior to initiating construction activities within the 100-year floodplain of the Santa Ynez River, construction sites and access roads within the riverbed, as well as riverbed areas within 300 feet of the construction site and access road, shall be inspected by a qualified biologist for the presence of the listed species, California red-legged frog, and the non-listed species foothill yellow-legged frog, Coast Range newt, silvery legless lizard, western pond turtle, two-striped garter snake, and American badger.

If any of these species are discovered within the construction work areas and access roads, these areas shall be cleared of the species listed above immediately before the prescribed work is to be carried out and immediately before any equipment is moved into or through the affected habitat areas. The removal of such species shall be conducted by a qualified biologist using procedures approved by the USACE and CDFG, and with the appropriate collection and handling permits. Species shall be relocated to nearby suitable habitat areas but sufficiently distant from the construction area to minimize the likelihood of their return.

TER-2 A qualified biologist shall be retained as a construction monitor to ensure that incidental construction impacts on biological resources are avoided, or minimized, and to conduct pre-grading field surveys for special- status plant and wildlife species, including those species listed in Mitigation Measure TER-1 that may be destroyed as a result of construction or site preparation activities. Responsibilities of the construction monitor include the following:

The construction monitor shall attend pre-grade meetings to ensure that timing or location of construction activities do not conflict with mitigation requirements ( e.g., seasonal surveys for plants and wildlife).

Mark or flag the construction area in the field with the contractor in accordance with the final approved construction plan.

Supervise cordoning of natural areas that lie outside grading areas identified in the construction plans (e.g., with temporary fence posts and colored rope).

Conduct a field review of the staking (to be set by the surveyor) designating the limits of all construction activity. Any construction activity areas immediately adjacent to riparian areas or other special- status resources may be flagged or temporarily fenced by the monitor, at his or her discretion.

Conduct meetings with the contractor and other key construction personnel describing the importance of restricting work to designated areas. The monitor should also discuss procedures for minimizing harm or harassment of wildlife encountered during construction.

Periodically visit the site during construction to coordinate and monitor compliance with the above provisions.

TER-3 Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities shall be coordinated with the construction monitor.
1116
TER-4 Vehicles and equipment shall not be operated in areas of ponded or flowing water or where wetland vegetation, riparian vegetation, or aquatic organisms may be destroyed unless there are no practicable alternative methods to accomplish the construction work, and only after prior approval by the CDFG and USACE. Approval shall be acquired by submitting a request to CDFG and USACE no later than 30 days prior to construction. The request must contain a biological evaluation demonstrating that no sensitive fish, amphibians, or reptiles are currently present, or likely to be present during construction, at the construction site or along access roads.

TER-5 Temporary sediment retention ponds shall be constructed downstream of construction sites that are located in the 100-year floodplain under the following circumstances:
the construction site contains flowing or ponded water that drains off site into the undisturbed streamflow or ponds; or
streamflow is diverted around the construction site, but the work is occurring in the period November 1 through April 15 when storm flows could inundate the construction site.

The sediment ponds shall be constructed of riverbed material and shall be located away from areas of ponded or flowing water to prevent discolored, silt-bearing water from reaching areas of ponded or flowing water during normal flow regimes.

To the extent possible, ponds shall be located in barren or sandy areas devoid of existing riparian scrub, riparian woodland, or aquatic habitat. The ponds shall be maintained and repaired after flooding events, and shall be restored to preconstruction grades and substrate conditions within 30 days after construction has ended at that particular site. The location and design of sediment retention ponds shall be included in the Storm Water Pollution Prevention Plan (SWPPP) prepared by the City for all construction activities that require a NPDES General Construction Activity Storm Water Permit.

TER-6 Water containing mud, silt, or other pollutants from construction activities shall not be allowed to enter a flowing stream, standing pools that native fauna may occupy, or be placed in locations that may be subject to normal storm flows during periods when storm flows can reasonably be expected to occur.

TER-7 Stationary equipment such as motors, pumps, generators, and welders that may be located within the riverbed construction zone shall be positioned over drip pans. No fuel storage tanks or equipment maintenance shall be allowed within the 100-year floodplain.

TER- 8 Focused surveys for potentially occurring special- status plant species shall be conducted by a qualified botanist prior to the commencement of construction related activities within suitable on site habitat areas. The surveys shall be conducted no more than one year prior to commencement of construction activities within suitable habitat and during the appropriate season for detection of the target species. Should individuals of the species be documented within Well Sites A and B and any other impacted locations, a rescue/ replacement plan shall be developed prior to the issuance of grading permits and implemented by the City or its designee in accordance with the plan provisions. Undeveloped portions of the Well Sites A and B, and any other impacted locations, shall be used as receptor sites for 1117
transplanted individuals or seeds. Other suitable mitigation sites may be used upon approval by USACE, CDFG and the City and/ or County. The plan shall demonstrate the feasibility of replacing the number of individual plants to be removed at a 1:1 ratio (of individual plants for woody species, and on an aerial basis for annual and herbaceous species). The plan shall specify the following:

1. the location of mitigation;

2. methods for harvesting seeds, and salvaging and transplantation of individual plants to be impacted;

3. site preparation procedures for the mitigation site;

4. a schedule and action plan to maintain and monitor the mitigation area;

5. a list of criteria and performance standards by which to measure success of the mitigation site;

6. measures to exclude unauthorized entry into the mitigation areas; and

7. contingency measures in the event that mitigation efforts are not successful.

TER-9 Pre construction surveys for bat roosts within the project impact area shall be conducted no earlier than one week prior to the commencement of any construction activity. If potential roosting habitat is found in Wells Sites A and B or other project locations, exclusion of bats shall be accomplished by identifying primary exit points and sealing all other escape routes greater than 0.25 inch. Care shall be taken to avoid sealing bats into the roost by placing a one-way valve over the primary exit points to prevent reentry. Simple one-way valves may be constructed using wire mesh cones, PVC, and strips of clear plastic sheeting attached over exit points. Once the bats have been excluded, roost spaces can be permanently filled with a suitable substance. In order to minimize disturbance to bats, it is recommended that exclusion be initiated during the winter months when the fewest bats are present.

TER-10 In order to compensate for permanent removal of jurisdictional habitats, including but not limited to sensitive vegetation types, the applicant shall control giant reed and other invasive exotic plant species within the project site to improve and expand wildlife and endangered species habitat, reduce flooding, erosion, and fire hazards, improve water quality; and potentially increase stream flow and water quantity in the project watercourses. Removal areas shall be kept free of exotic plant species for 5 years after initial treatment. In areas where extensive exotic removal occurs, revegetation with native plants or natural recruitment shall be documented.

TER-11 Vegetation types temporarily impacted by the proposed project will be restored.

Native vegetation within temporary construction areas shall be mulched and set aside. Large trunks of removed trees may be utilized on site to provide habitat for invertebrates, reptiles, and small mammals or may be anchored within the project site for erosion control. If the timing of the mulching and application is appropriate, the native mulch will be spread over the temporary impact areas in order to facilitate revegetation. If the period of mulch storage exceeds approximately one month, fresh native mulch may be applied to the temporary impact areas to provide seed propagules and native biomass. Should the timing not be appropriate for using the native vegetation as mulch, non-clear pliable plastic sheeting shall be used.

After the completion of Year 1, a biologist will evaluate the progress of the passive 1118
restoration approach in the temporary impact areas to determine if natural recruitment has been sufficient for the site to eventually reach performance goals.

In the event that native plant recruitment is determined by the project biologist to not be adequate for successful habitat establishment, the applicant or its designee shall revegetate the temporary construction areas in accordance with the methods designed for permanent impacts (i.e., seeding, container plants, or a temporary irrigation system may be recommended).

Areas temporarily disturbed by construction activities shall also be weeded annually, as needed, for up to 5 years following construction. Weeds shall be removed by hand, an approved herbicide application, or by mechanical equipment. These areas shall be annually monitored for 5 years after construction to document vegetation type establishment.

In the event that native plant cover does not reach 50 percent of the preconstruction native plant cover within 3 years, the City shall revegetate the temporary construction.

TER-12 Prior to the drilling and construction of any wells in Wells Sites A or B, the City shall develop a habitat enhancement and restoration plan to improve the quality of the riverine and wetland functions associated with on-site portion of the Santa Ynez River in the vicinity of proposed well sites. Enhancement and restoration actions will include control of invasive plant species ( e.g., Italian stone pine, Peruvian- pepper Schinus molle], fennel, castor-bean, white melilot, tree tobacco, date palm, and smilo grass [Piptatherum miliaceum]), creation of native riparian and scrub habitat, and for the planting of appropriate locally indigenous species for the habitat created.

TER-13 Active nests of native bird species are protected by the Migratory Bird Treaty Act (16 U.S.C. 704) and the California Fish and Game Code (Section 3503). If activities associated with construction or grading are planned during the bird nesting/ breeding season, generally January through March for early nesting birds e.g., Coopers hawks or hummingbirds) and from mid-March through September for most bird species, the City shall have a qualified biologist conduct surveys for active nests. To determine the presence/ absence of active nests, pre-construction nesting bird surveys shall be conducted weekly beginning 30 days prior to initiation of ground- disturbing activities, with the last survey conducted no more than three days prior to the start of clearance/ construction work. If ground- disturbing activities are delayed, additional pre-construction surveys shall be conducted so that no more than three days have elapsed between the survey and ground- disturbing activities. 1119

The cultural resource inventory for the Project included a literature review and records search of the California Historic Resource Information System ( CHRIS) and a review of the Sacred Lands File (SLF) by the Native American Heritage Commission ( NAHC). The purpose of the inventory was to update to the existing cultural study conducted in 2011 by Compass Rose Archaeological, Inc. for the City of Solvang’ s Water System Master Plan Update ( Toren and Romani 2011) ), incorporated as Appendix 5.4 of the EIR (State Clearinghouse No. 2011011007) for the 2011 Water System Master Plan Update that was certified in February 2014 ( Certified EIR). As part of the 2011 Master Plan Update and analyzed in the Certified EIR, the City of Solvang ( City) had proposed to install up to six (6) new wells, with a capacity of about 300 gallons per minute ( gpm) each, and install filtration facilities so that the City will be able to meet potable water standards even when some wells are under the influence of surface water.

Under the Proposed Revised Project, the City now proposes to reduce the number of new wells considered in the 2011 Water System Master Plan Update Certified EIR from six (6) to two (2) new river wells (Proposed Revised Project). Considered in the Certified EIR, the proposed well site would be located downstream of Alisal Bridge in Site B as depicted on Exhibit A. Thus, the new wells would be within the area previously identified and analyzed in the Certified EIR. No new wells are proposed in Well Site A. Supporting well infrastructure, which was evaluated in the 2011 Water System Master Plan Update Certified EIR, would also be constructed as part of the Proposed Revised Project that would connect the new wells to the City’ s existing water distribution system.

The new wells would connect to a new 12-inch diameter waterline to be constructed from the new wells approximately 2,000 feet length to the City’ s existing water distribution system at the western end of Fjord Drive. The proposed width of the pipeline easement area and associated buffer is 40 feet wide in total (a 20-foot easement with a 10 foot buffer on both sides). The Proposed Revised Project components would occur within the analyzed footprint of May 26, 2021

the Certified EIR. This memorandum summarizes the results of the updated cultural resource inventory efforts for the Proposed Revised Project.

The literature review and records search were conducted on March 24, 2021 by Matthew V.C.

LoBiondo, Assistant Coordinator at the Central Coast Information Center (CCIC) of the CHRIS housed at the University of California, Santa Barbara. The records search included Well Site A, Well Site B, and the proposed and existing easements (as depicted on the River Wells Project Well Siting Plan included in the City of Solvang Permit 15878 [Application 22423] dated October 19, 2020) as well as a one-mile (1 mile) radius (Exhibit B). The purpose of the records search was to identify any known cultural resources and prior cultural studies that had been conducted in the immediate vicinity of the Project area. The records search also included a review of the Office of Historic Preservation Archaeological Determination of Eligibility and the Office of Historic Preservation Directory of Historic Properties Data File.

The records search indicated that 71 previous studies have been conducted within one mile of the Project area. Eight of these studies included or intersected the Project area (Table 1). Thirtysix cultural resources were identified within the records search area, one of which (42- 002641/CA-SBA-2641) is immediately adjacent to the proposed water main at the intersection of Fjord Drive and Glen Way. The site consists of a sparse scatter of prehistoric flaked and ground stone artifacts that measures 260 by 70 meters in area. As stated by Toren and Romani 2011), the site record on file at the CCIC does not indicate any subsurface testing or significance evaluation efforts were conducted at the site. Additionally, a review of historical topographic maps indicates a currently operational gravel pit is located within the parameters of the possible location of Well Site B; the sand and gravel pit was in operation as early as 1942 which means this facility is of historic-age.

PaleoWest contacted the NAHC for a review of the SLF on March 25, 2021. The objective of the SLF search was to determine if the NAHC had any knowledge of Native American cultural resources (e.g., traditional use or gathering area, place of religious or sacred activity, etc.) within the immediate vicinity of the Project area. The NAHC responded on April 6, 2021, stating that the SLF was completed with positive results and that the Santa Ynez Band of Chumash Indians should be contacted for additional information. In addition to the Santa Ynez Band of Chumash 1124
Indians, the NAHC recommended that 10 Native American individuals representing 6 tribal groups be contacted to elicit information regarding cultural resource issues related to the Proposed Revised Project (see Exhibit C for a copy of the response letter received from the NAHC). PaleoWest is aware that the Santa Ynez Band of Chumash Indians were consulted and participated in a meeting with the City during the Senate Bill 18 consultation efforts conducted for the Project in 2011 (Meridian 2014). Subsequent to the adoption of the 2014 Certified EIR, Assembly Bill (AB) 52 was adopted requiring lead agencies to analyze the impacts of a project on "tribal cultural resources" separately from archaeological resources and engage in consultation with California Native Tribes. AB 52 applies to projects that have a notice of preparation or notice of intent filed on or after July 1, 2015. As such, no AB 52 consultation is required for this project at this time.

The City of Solvang’s 2014 Certified EIR identified potentially significant impacts to the cultural resources and, as such, proposed mitigation measures to reduce these potential impacts to a less than significant level. The adopted mitigation measures identified in the 2014 Certified EIR include monitoring by an archaeologist and a local Santa Ynez Chumash tribal monitor of any construction involving ground-disturbing activities (CUL-4: Meridian 2014). In addition, the adopted mitigation measures require supplemental cultural resource studies for areas that may be impacted outside of the previously surveyed areas at Well Site A, Well Site B, and the proposed water treatment plant (CUL-2: Meridian 2014) as well as a mitigation measure stating that if any archaeological resources are encountered during ground-disturbing activities work will immediately be stopped and redirected until the resources can be further investigated CUL-3: Meridian 2014). All three of these adopted mitigation measures in addition to the unanticipated discovery of human remains protocols outlined in CUL-5 are still applicable for the Proposed Revised Project in order to reduce potential impacts to cultural resources to a less significant level.

It has been a pleasure working with you on this Project. If you have any questions, please do not hesitate to contact me at [email protected].

Sincerely,
Roberta Thomas, M.A., RPA | Senior Archaeologist/Project Manager

Re: Solvang River Wells ( Sites A and B) ( 21- 0093) Project, Santa Barbara County Dear Ms. Thomas:

A record search of the Native American Heritage Commission ( NAHC) Sacred Lands File (SLF) was completed for the information you have submitted for the above referenced project. The results were positive. Please contact the Santa Ynez Band of Chumash Indians on the attached list for more information. Other sources of cultural resources should also be contacted for information regarding known and recorded sites.

Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated; if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received.

If you receive notification of change of addresses and phone numbers from tribes, please notify me. With your assistance, we can assure that our lists contain current information.

If you have any questions or need additional information, please contact me at my email address: Sarah.Fonseca@nahc. ca.gov.

Sincerely,
Sarah Fonseca
Cultural Resources Analyst

City of Solvang
River Wells Project - Project Description ( Updated)
Title: City of Solvang River Wells Project, Revised 09/27/21 Lead Agency/Project Applicant:

City of Solvang
1644 Oak Street
Solvang CA, 93463
Matt van der Linden, Utilities Director
805) 688-5575 x222
Project Description: The City proposes to install additional wells in the Santa Ynez River and produce the river underflow within its rights under State Water Resources Control Board SWRCB) Diversion Permit 15878. In May 2015 the City submitted two Petitions: 1) Petition for Time Extension, and 2) Petition for Change in Reach of Diversion. On August 7, 2020 the City filed a letter with the State Water Resources Control Board withdrawing its Petition for Extension of Time and modifying its Petition for Change in Reach of Diversion, which the Board acknowledged in its October 2, 2020 order. The City also submitted a revised project description on October 19, 2020. The City is now further revising its Petition for Change in Reach of Diversion and project description in response to comments from, and negotiations with, protesting parties.

As compared to the 2015 Petition for Change, the City is requesting to ultimately reduce its Reach of Diversion and shift it downstream. The City’s requested final Revised Reach of Diversion is to begin at the Alisal Bridge and extend approximately 8,060 feet downstream. However, in the interim, the City will continue to divert water from its existing well 7A above the Alisal Bridge until it and the existing reach of diversion upstream of the Alisal Bridge are abandoned. See attached proposed Revised Reach of Diversion Map. In addition, the City has elected to:
significantly limit its proposed river well production to its historical maximum annual diversion of 1,368 AFY,
limit its production rate to a maximum of 2.84 cfs,
install no more than two new river wells (as opposed to the six proposed in the initial petition), and
locate any new wells 3,500 feet or more downstream of the Alisal Bridge in Site B area evaluated in the 2014 Certified EIR.

See attached proposed Revised River Wells Site Plan. The City is also electing to cease production from Well 3 and Well 7A if flows at the Alisal Bridge (as monitored by the USGS flow gage) drop below 1.5 cfs or if subsurface water flows drop below 360.3 as measured at the Alisal Ranch Well.

Further, the City will not increase the existing production capacity of Well 7A and Well 3 above 200 gpm and 350 gpm, respectively. The City will also abandon its Well 7A and its existing reach of diversion upstream of the Alisal Bridge once the combined production capacity of Well 3 and any new downstream wells is at least 950 gpm or Solvang constructs two new wells in Site B as shown in the attached Revised River Wells Site Plan. The City maintains an easement for Well 5 that was destroyed several years ago) but will not reconstruct this well or use this well site. See attached proposed Revised Reach of Diversion Map.
1207

The City has elected to make these changes to the Project in a good faith effort to resolve the Protesters concerns and minimize possible impacts on Alisal and ID No.1 river wells, but such changes do not constitute an admission by the City to any of the Protesters claims, assertions or arguments.

The significant benefits of the new River Wells are: 1) water produced from the wells is the most cost effective water source available to the City, 2) additional wells will improve the City’s ability to meet fire flow demands and peak demands during the summer, and 3) use of river water will improve water supply reliability by allowing conjunctive use of both local and imported water supplies. The City’s future peak daily demand at Buildout is estimated at 5.19 cfs. The City’s River Wells and other sources of supply would be required to meet this demand.

Based on the Water Master Plan Update (April 2011) and Integrated Water Supply Management Plan (October 2018), the City’s anticipated future water supply by source has been updated and is shown in Table 2 below. As demonstrated below, the long-term average production from the City’s Santa Ynez River Wells is anticipated to be 650 AFY. However the City is requesting a production level of 1,368 because the City’s need for water from the River Wells will vary from year to year depending on availability from other water supply sources and climactic conditions. The requested production level of 1,368 AFY will accommodate these fluctuations and ensure the City has sufficient water supply for existing and future uses. See Water Code Section 106.5 (the City’s water rights “should be protected to the fullest extent necessary for existing and future uses.”) Table 1 - Total Water Production Based on the Master Plan (Updated) Current and Anticipated Future Supply by Source

Notes:
1) Higher production is expected from this source in certain years, while in other years production will be limited based on climatic conditions.
2) Higher amounts could be obtained from this source. However, use is minimized due to the high cost of this source.

Project Location: As described above, the Project consist of two new River Wells and approximately 2,000 feet of 12” diameter waterline. The two proposed River Wells and associated waterlines will be located along the north side of the Santa Ynez River west of the City of Solvang in Site B as described and evaluated in the 2014 Certified EIR and as shown in the attached proposed Revised River Wells Site Plan. The two proposed River Wells and associated waterlines will be located a minimum of 150 feet back from the high water mark of the River. The proposed waterline will extend from the City’s existing water distribution system at the west end of Fjord Drive westerly approximately 2,000 feet to the proposed new River Wells area. The two new 1208

River Wells will be located a minimum of 1,000 feet apart. See attached proposed Revised River Wells Site Plan.

Project Objectives: The primary objectives of this revised River Wells Project remain the same as objectives of the City of Solvang’ s 2011 Water Master Plan Update and 2014 Certified EIR as follows:

1. Ensure a future reliable water supply to meet the projected water demand at City build out as provided for in the General Plan.

2. Provide for a reliable and diversified water supply through the use of multiple sources of supply.

3. Secure adequate water rights to reliably meet the City’s water supply requirements.

4. Provide the needed water supply at a reasonable cost.

5. Avoid impacts either to public trust resources or to other water rights holders.

Background and Comparison with the 2015 Petition for Change: The SWRCB Diversion Permit 15878 was issued to Solvang Municipal Improvement District ( SMID), the City’s predecessor in interest, in 1969. The City’s Diversion Permit 15878 contemplated diversion by SMID of water from the Santa Ynez River up to 5 cubic feet per second (cfs) and up to 3,600 acrefeet per year (AFY). The 2011 Water Master Plan Update identified an average annual diversion rate of up to 5 cfs from the existing and new River Wells - for a total diversion of approximately 1,980 AFY. The City of Solvang Water Master Plan Update (April 2011) provides details on the existing City water system, proposed future upgrades, and new facilities to supply water to the current and future residents and businesses of the City. The City’s Integrated Water Supply Management Plan ( October 2018) provides additional recommendations on water sources and water supply planning.

The City’s existing Reach of Diversion begins at the Alisal Bridge and extends upstream for a distance of approximately 11,321 feet. The City currently has two active river wells, Wells 3 and 7A. Well 3 is located immediately downstream of the Alisal Bridge and Well 7A is located approximately 800 feet upstream of the Alisal Bridge. Well 7A is located approximately 700 feet upstream of Alisal Ranch Well 2, and approximately 3,800 feet downstream of ID1’ s nearest river well. The City’s original Petitions in May 2015 requested an expanded Reach of Diversion that would have added approximately 8,000 feet of reach of diversion downstream of Alisal Bridge to the existing reach of diversion upstream ofthe Alisal Bridge. Under the revised project description, in the interim, the City will continue to divert water from its existing well 7A above the Alisal Bridge until it and the existing reach of diversion upstream of the Alisal Bridge are abandoned.

However, the final Reach of Diversion under the revised project description will be significantly reduced in total linear feet to approximately 8,060 feet downstream and located entirely downstream of the Alisal Bridge.

It should be noted that in the original 2011 Water Master Plan and 2014 Certified EIR, construction of a new water treatment plant was included to treat water produced from City River Wells. It has since been determined that a water treatment plant is not needed. The proposed treatment plant has been deleted from the project description. The proposed well design is unchanged from that presented in the 2014 Certified EIR. The maximum well depth will be approximately 65 feet.

A summary of the differences between the original May 2015 Petitions and Project, and revised Petition and Project is provided in Table 3 below.
