SE
CTION 1. The findings for Zone Change Z -S-2025-0003 and Specific Plan Amendment SP -S-2025-0002 contained in the Planning Commission Resolution dated June 3, 2026, and incorporated herein by reference, are hereby adopted.

SE
CTION 2. Environmental Assessment. Because of the facts set forth in Section 1, the Director completed an Initial Study for Z -S-2025-0003 and SP -S-2025- 0002. Thereafter, the Director prepared an Addendum to the certified Environmental Impact Report (EIR) and Mitigation Monitoring and Reporting Program (MMRP) in accordance with CEQA Guidelines § 15063, which is incorporated by reference, and the Director is authorized to file a Notice of Determination in accordance with CEQA Guidelines § 15075 and any other applicable law.

SE
CTION 3. Pursuant to SVMC 9 -20.030 and 9-73, Zone Change No. Z - S-2025-0003 removing the Commercial Recreation (CR-SP) Zone and reconfiguring the Open Space (OS-SP), Residential Estate (RE-SP), Residential Low Density (RL-SP), and Residential Medium Density (RM-SP) Zones, as contained in Exhibit B, attached hereto, is hereby approved.

SE
CTION 5. Validity of Previous Code Sections. If the entire Ordinance or its application is deemed invalid by a court of competent jurisdiction, any repeal of the SVMC or other regulation by this Ordinance will be rendered void and cause such SVMC provision or other regulation to remain in full force and effect for all purposes.

SE
CTION 6. Limitations. The City Council’s analysis and evaluation of the project is based on the best information currently available. It is inevitable that in evaluating a project, it is based on the best information currently available. It is inevitable that in evaluating a project, absolute and perfect knowledge of all possible aspects of the project will not exist. One of the major limitations on analysis of the project is the Cit y Council’s lack of knowledge of future events. In all instances, best efforts have been made to form accurate assumptions. Somewhat related to this are limitations on the City’s ability to solve what are, in effect, regional, state and National problems and issues.

The City must work within the political framework within which it exists and with the limitations inherent in that framework.

SE
CTION 7. Preservation. Repeal or amendment of any previous SVMC Sections does not affect any penalty, forfeiture, or liability incurred before, or preclude prosecution and imposition of penalties for any violation occurring before this Ordinance’s effective date. Any such repealed part will remain in full force and effect for sustaining action or prosecuting violations occurring before the effective date of this Ordinance. 3 Ord. No. 1374

SECTION 8. Severability. If any part of this Ordinance or i ts application is deemed invalid by a court of competent jurisdiction, the City Council intends that such invalidity will not affect the effectiveness of the remaining provision or application, and to this end, the provisions of the Ordinance are severable.

SECTION 9. Summaries of Information. All summaries of information in the findings, which precede this section, are based on the substantial evidence in the record.

The absence of any particular fact from any such summary is not an indication that a particular finding is not based in part on that fact.

SECTION 10. Publication. The City Clerk is directed to certify the passage and adoption of this Ordinance; cause it to be entered into the City of Simi Valley’s book of original ordinance; make a note of the passage and adoption in the records of this meeting; and, within 10 days after passage and adoption of this Ordinance, cause it to be published or posted in accordance with California law.

SECTION 11. Incompatible Provisions. To the extent of any provision of this Ordinance is incompatible with or at variance with any prior adopted ordinance or resolution, the provisions of this Ordinance shall take precedence.

SECTION 12. The City Clerk shall cause this ordinance or a summary hereof to be published in a newspaper of general circulation, published in the County of Ventura and circulated in the City, and if applicable, to be posted, in accordance with Section 36933 of the California Government Code; shall certify to the adoption of this ordinance and shall cause a certified copy of this ordinance, together with proof of publication, to be filed in the Office of the Clerk of this City.

SECTION 13. This ordinance shall go into effect and be in full force and effect at 12:01 a.m. on the thirty-first (31st) day after its passage.

I. Introduction
The Simi Valley General Plan is a statement of development policies that establish goals, standards and plans for the physical, social and economic development of the community. The City of Simi Valley has grown and changed considerably since the adoption of the ﬁrst General Plan in 1972. Some of the new trends and issues that have emerged which affect the land use of Simi Valley are community growth, increased employment opportunities, social and population changes, development patterns and the increased cost of housing. The area has matured into a community accommodating diversiﬁed age groups, lifestyles and range of incomes. To better satisfy these changing needs of the community, the General Plan requires a Speciﬁc Plan of development for certain areas of the City. A Speciﬁc Plan is a plan adopted for a particular area of the City that implements the General Plan and its policies, and creates the standards and criteria by which development will proceed. Particularly within large, vacant areas, Speciﬁc Plans allow for a comprehensive approach to addressing matters such as design and circulation that should be detailed prior to any one portion developing by itself.

A. Purpose and Intent
A Speciﬁc Plan is a detailed version of the City’s General Plan for a focused area that speciﬁcally delineates concepts, regulations, and conditions to be applied to the future development of the speciﬁed area. By adopting a Speciﬁc Plan for a development area, the City of Simi Valley directly establishes the density, housing type, and character of the planned development while ensuring the type and location of the infrastructure required, as well as setting the standards for development to occur. Essentially, the Speciﬁc Plan is the guide established by the City to ensure the envisioned development of the area. The Whiteface Speciﬁc Plan (as amended and updated) and applicable City ordinances, regulations, and procedures deﬁne the residential unit types and locations in addition to imaginative community design concepts. The two volumes comprising this document also establish development controls to provide the City with the assurance that development within each of the canyons will be as it was envisioned at the time of approval.

B. Legal Authority
The California Government Code, Article 8, Sections 65450 through 65457, authorizes the City of Simi Valley to prepare, adopt, and amend Speciﬁc Plans for areas of the City that are deemed necessary. The City of Simi Valley has established speciﬁc procedures, requirements, and ﬁndings for the review, adoption, and implementation of Speciﬁc Plans within the City of Simi Valley Municipal Code, Title 9, Article 5, Chapter 9-56.

Adoption and amendment of the Whiteface Speciﬁc Plan by the Simi Valley City Council makes this document the governing standard for the basic development of the Speciﬁc Plan area. All applicable development and design standards of the Simi Valley Municipal Code will apply to this development, unless the standard is provided in this Speciﬁc Plan.

Adoption and amendment of the Speciﬁc Plan does not imply approval for future building permits.

August 2026 - I. Introduction
[13]
20 Ord. No. 1374
The adoption and amendment of the Speciﬁc Plan does not constitute a vesting of rights to construct any of the land uses or improvements described herein. No existing provisions of state law, or provisions of state law as may hereafter be adopted, amended or judicially interpreted, shall be construed as authorizing the Speciﬁc Plan to constitute an entitlement or a vesting of rights to construct.

The existing Whiteface Speciﬁc Plan area is composed of three (3) developable canyon areas; the ﬁrst canyon includes the area of Sand Canyon, the second canyon is Dry Canyon, and the third is Tapo Canyon. A number of unrelated development ﬁrms could be responsible for building out and implementing this Speciﬁc Plan. Because of their mutual involvement in the project but separate and distinct interests for the construction of the development areas, governance will be stated as follows protecting the rights and interests of each developer:

If any developer should choose to amend or make an adjustment to any particular regulation, condition, program, or portion of this Speciﬁc Plan, then such change will have no corresponding or identical impact upon similar sections of any other separate, distinct, and independent portion of the Speciﬁc Plan. For instance, a developer’s proposed changes to the Speciﬁc Plan affecting the Sand Canyon development will not affect the development policies as established within the Speciﬁc Plan for Dry Canyon or Tapo Canyon, as these canyons may be developed by other unrelated development ﬁrms.

If any regulation, condition, program, or portion of this Speciﬁc Plan is held invalid or unconstitutional by any court of applicable jurisdiction, such portion will be deemed a separate, distinct, and independent provision and the invalidity of such provision will in no way affect the validity of the remaining provisions.

C. GOALS AND OBJECTIVES
The primary objective of the Whiteface Speciﬁc Plan is to implement the development guidelines and policies of the current City of Simi Valley General Plan and Hillside Performance Standards through a carefully planned development.

The following goals were established to guide the development of the Whiteface Speciﬁc Plan area into a planned development that harmoniously incorporates the natural environment and the surrounding community in conformance with Simi Valley Hillside Performance Standards and policies of open space, recreation, circulation, land use and density, as well as community character:

1. Provide a comprehensive plan of urban and suburban development within three canyons as identiﬁed within Appendix B, Section H of the Simi Valley General Plan that will include open space and recreation, and public and private secured residential communities.

2. Establish consistency with, and implementation of, the City of Simi Valley General Plan goals, objectives, and policies.

3. Implement a comprehensive program for the physical and economic development of the property.

21 Ord. No. 1374

4. Provide a diverse community of detached single family homes in the Sand Canyon area that is purposefully designed to be consistent with the development goals of the City of Simi Valley General Plan.

5. Provide for the opportunity of the development of new single family residences which will be served by public and private streets and will preserve signiﬁcant land forms while creating a rural residential setting.

6. Establish a community that provides a variety of housing types to meet the needs of middle, and upper income families and individuals living in Simi Valley and surrounding communities.

1. General Plan Community Development Element Goals
The Whiteface Speciﬁc Plan supports and complements the following goals within various elements of the General Plan.

GOAL LU-1: Growth and Change. Sustainable growth and change, achieved through orderly and well-planned development, meet the needs of existing and future residents and businesses, ensure the effective and equitable provision of public services, and efficiently use land and infrastructure.

GOAL LU-3: City Structure and Form. Land uses are located, designed, and scaled to respect Simi Valley’s natural setting; maintain distinct and interconnected places for residents to live, shop, work, and play; and reduce automobile dependence.

GOAL LU-6: Open Spaces. Open space lands are preserved to maintain the visual quality of the City, provide recreational opportunities, protect the public from safety hazards, and conserve natural resources and wildlife.

GOAL LU-7: Viewsheds. Vistas of the hillsides, valley ﬂoor, city entrance areas, recreation areas, major open space areas, and viewsheds from the hills are maintained for the public.

GOAL LU-12: Neighborhood Identity. Residential neighborhoods are provided that are distinctly identiﬁed and differentiated from one another in consideration of geography, character, and lifestyle.

GOAL LU-32: General Plan and Zoning Consistency. Development proposals within the city are consistent with the General Plan Policies and Land Use Designations identiﬁed on the General Plan Land Use Map.

The Whiteface Speciﬁc Plan provides a comprehensive plan of development within three (3) canyons, Sand, Dry, and Tapo Canyons. It is the intent of the Whiteface Speciﬁc Plan to site the residential areas, recreational facilities, and other public and private improvements in an effort to complete the development of the area in a manner sensitive to topography, landforms, natural vegetation, and neighboring views. Public and private roadways will provide required circulation within the Whiteface Speciﬁc Plan area, and will be integrated into the City of Simi Valley’s overall system of roadways.

2. General Plan Natural Resources Element Goals
GOAL NR-1: Natural Resource Conservation. Natural resources of importance to the City of Simi Valley and its Planning Area are conserved, enhanced, and protected.

GOAL NR-2: Vegetation and Habitat Preservation. Plant and wildlife habitat are preserved and enhanced and wildlife movement corridors are protected.

Au gust 2026 - I. Introduction Whiteface Speciﬁc Plan
Volume II - Lost Canyon
[16]
23 Ord. No. 1374
GOAL NR-3: Visual Resource Protection. Signiﬁcant visual resources are preserved as important quality-of-life amenities for residents and as assets for recreation and tourism.

The Whiteface Speciﬁc Plan designates a signiﬁcant portion of the area as open space.

That portion of the Santa Susana Mountains known as Whiteface, including slopes facing Simi Valley to the south, the summit, and the primary landforms within the adjacent canyon areas, are thereby preserved.

The Lost Canyons Conceptual Land Use Plan (Exhibit #6) protects the prominent ridgelines, and unique natural land features and enhances the new community by maintaining the open character of the hillsides. The hillsides should be protected by locating residential development primarily within the previously disturbed areas of the Project Site.

3. General Plan Housing Element Goals
GOAL HE 1: Balanced Community. A balanced community with services and housing opportunities is created for all.

The Whiteface Speciﬁc Plan creates a sense of “neighborhood” within each of the three (3) canyons, and a feeling of “community” throughout the Speciﬁc Plan area.

A variety of housing types and lot sizes will be planned to appeal to a diverse range of family types, sizes and needs.

4. General Plan Community Services Element Goals
GOAL PR-1: Parks and Recreation Facilities. Parks, recreation, and community facilities that enhance community livability and contribute to public health are available to serve the diverse recreational needs of residents and visitors.

GOAL PR-3: Accessible and Connected Trail System. An interconnected and accessible trail system is available to provide connections to community facilities, recreational areas, public and private schools, regional trails, canyons, hills, and open space to provide an important recreational opportunity throughout Simi Valley.

The Whiteface Speciﬁc Plan establishes recreation resources which integrate public and private facilities, including large areas of open space and a public park surrounded by open space located in the Sand Canyon area. The public park in Sand Canyon will be designed to have at least one active recreational element.

There will be three public/private passive recreational areas within the Sand Canyon area that will be maintained by the Homeowner’s Association. The open space will be traversed by a trail system with designated trailheads that will provide access to the regional trail system as designated on General Plan Figure PR-2 - Trails.

August 2026 - I. Introduction

24 Ord. No. 1374

5. General Plan Mobility and Infrastructure Element Goals GOAL M-1: Safe and Efficient Transportation System. The safe and efficient movement of people, goods, and services is provided by encouraging the design, construction, and maintenance of an integrated mobility and circulation system, including roads, transit, bike paths, sidewalks, and commuter rail.

GOAL M-3: Roadway Design. A safe and efficient roadway circulation system is provided within the City that minimizes the impact on residential areas, maintains the suburban character of the community, and accommodates conservative growth within the City of Simi Valley.

Public roadways have been conﬁgured to provide connections to the City of Simi Valley’s roadways as identiﬁed within the Circulation Element of the General Plan.

The planned phasing of roadways will provide safe and efficient access within each of the three (3) canyon areas.

D. Plan Organization
Several development ﬁrms may be responsible for the development of the proposed Whiteface Speciﬁc Plan area because the three (3) canyons are separate areas subject to independent sale. The City requires that all three (3) canyons be one (1) Speciﬁc Plan.

The Whiteface Speciﬁc Plan has been organized into two (2) volumes, each with four (4) chapters, each introducing a particular aspect of the Speciﬁc Plan: 1) Introduction, 2) Overall Project, 3) Big Sky Ranch/Sand Canyon (within Volume 1), 3) Lost Canyons/Dry & Tapo Canyon (within Volume II), and 4) Plan Implementation. Chapters 2 and 3 are of particular interest for the planning and physical development of the Speciﬁc Plan areas.

Chapter 2 describes the site and physical characteristics of the entire Speciﬁc Plan area while identifying the required infrastructure and location of a circulation system designed to mitigate impacts of the proposed development.

Chapter 3 identiﬁes and describes the three (3) canyon areas as separate and distinct development areas. Chapter 3 of Volume I introduces Big Sky Ranch/Sand Canyon, the ﬁrst of three (3) canyon development areas to be discussed within the Speciﬁc Plan.

Chapter 3 of Volume II introduces the Lost Canyons project located within Dry and Tapo Canyons. These sections address the General Plan requirements speciﬁc to each canyon development area along with a land use summary, infrastructure, architectural concept, homeowner’s association, landscaping guidelines, phasing, and energy conservation.

II. Overall Project
A. Site Description

1. Location
The Whiteface Speciﬁc Plan area is located within the City of Simi Valley (see Exhibit #1, Regional Location Map), and comprises approximately 2,779 acres in the lower foothills to the north of Simi Valley, within three (3) distinct canyon areas known as Sand Canyon, Dry Canyon and Tapo Canyon (see Exhibit #2, Project Vicinity Map, and Exhibit #4, Canyons Boundaries Map). The site is designated in the General Plan as a Speciﬁc Plan area (see Exhibit #9, General Plan Land Use Designations). The Speciﬁc Plan area is bounded on the south by open space, single family residences, and the l25-acre Simi Valley Regional Center Speciﬁc Plan area; on the west by the vacant 200-acre North First Street Speciﬁc Plan area and the 2,200-acre Alamos/Brea Canyons Speciﬁc Plan area; to the east along Tapo Canyon Road by open space and Marr Ranch, a 2,800 acre residential development; and to the north by undeveloped open space, including Whiteface, a community-wide landmark. Whiteface is a local name for an escarpment formed on the south slope of Big Mountain that exposes light colored shale.

2. Physical Characteristics
a. Natural Terrain
The Whiteface Speciﬁc Plan area encompasses foothills north of Simi Valley and the southern slopes of Big Mountain (see Exhibit #3, Physical Constraints for Sand, Dry and Tapo Canyons). Big Mountain is an isolated ridge within an east- west trending range situated between Simi Valley and the Santa Clara River that includes Oak Ridge (to the northwest) and the Santa Susana Mountains (to the northeast). The foothills and Big Mountain are composed of sedimentary strata (layers) that are chieﬂy inclined to the north at a moderate angle. Differential erosion has produced a cuesta topography (steep south facing slopes, gentle north-facing slopes). Relief within the Speciﬁc Plan area is approximately 1,270 feet, with the elevation ranging from 960 feet in the southwest corner of the area to 2,330 feet at the summit of Whiteface along the north boundary of the area.

Three major south draining canyons are encompassed within the Speciﬁc Plan area. From east to west these drainages are Tapo Canyon, Dry Canyon, and Sand Canyon. Tapo Canyon, located along the east margin of the Speciﬁc Plan area, is the largest of the three drainages. Tapo Canyon has headwaters north of the Speciﬁc Plan area and drains portions of Oak Ridge, Big Mountain, and the Santa Susana Mountains. Dry and Sand Canyons drain portions of the south slope of Big Mountain. In the Speciﬁc Plan area, Tapo Canyon has a relatively narrow alluvial ﬂoor with incised active channels. The south end of Tapo Canyon is narrow, but broad, low gradient tributary drainages are present in the central part of the Speciﬁc Plan area. These low gradient areas have been used for agriculture in the past.

[22]
29 Ord. No. 1374
Exhibit #3 - Physical Constraints for Sand, Dry and Tapo Canyons August 2026
[23]
30 Ord. No. 1374
Dry Canyon has a relatively wide alluvial ﬁlled active stream course within a steep sided canyon. Like Tapo Canyon, low gradient areas are present in the upper reaches of Dry Canyon near the base of Whiteface.

In contrast to the other major drainages, the Sand Canyon drainage is broad and open with extensive areas of low gradient. Actively eroding ravines have developed in the minor drainages within Sand Canyon. Headward erosion of these ravines appears to be a response to tectonic uplift of the foothills exacerbated by overgrazing of livestock.
b. Geology
The City of Simi Valley is located within the Transverse Ranges geomorphic province, which is characterized by a roughly east-west trending structural-grain and compressional tectonics. Simi Valley is formed by a broad, west plunging, synclinal fold in Tertiary rocks that is bound on the north by the Simi fault. North side up, reverse displacement on the active Simi fault has produced the sharp break in slope along the northern margin of the Valley and formed a sill at the northwestern end of the Simi Valley. Immediately north and roughly parallel to the Simi fault is the Simi anticline (and arch-like fold) that trends across the southern portion of the Speciﬁc Plan area. The anticline may represent a fault propagation fold on the hanging wall (upper block) of the Simi fault. North of the Simi anticline, the tertiary strata generally are inclined to the north, but are dissected by several east-west trending faults. Big Mountain, north of the Speciﬁc Plan area, is a hogback ridge composed of Tertiary rocks.

Tertiary sedimentary rocks are exposed within the Speciﬁc Plan area and are referred to the late Eocene to late Oligocene Sespe Formation, and Miocene Calabasas and Modelo formations. These rocks are extensively exposed in the Simi Valley region. Bedrock of the developable portions of the Speciﬁc Plan area consists of non-marine sedimentary rocks referred to the Sespe formation.

These rocks are generally poorly exposed in the southern part of the area, but moderately to well exposed in the northern portions of the area. In the Speciﬁc Plan area, the Sespe Formation consists chieﬂy of the very thickly bedded sandstone with interbeds of mudstone. The sandstone is more resistant to erosion and generally forms ridges, spurs, and steeper slopes. Areas of mudstone often exhibit highly expansive soil and a tendency to support annual vegetation, particularly grass.

Surﬁcial deposits within the Speciﬁc Plan area include alluvium, colluvium, older alluvium, debris ﬂow, rock avalanche deposits, landslides, and artiﬁcial ﬁll. Relative ﬂat lying, incoherent detrital sediments mantle the Tertiary rocks over most low gradient areas of the Speciﬁc Plan area. These sediments represent remnant alluvial (streambed) deposits. The older alluvium is highly variable in composition, but consists chieﬂy of sand with interbedded and lensing clay, silt, and gravel.

The older alluvial deposits are of Pleistocene age based on the occurrence of the extinct ground sloth, Glossotherium. Modern alluvium is present along segments of the active stream channels. The alluvium typically consists chieﬂy of sand and gravel. Slope wash (colluvium) is present in low gradient tributary drainages and on the lower canyon slopes. The colluvium consists chieﬂy of clayey to silty sand.

The Sespe Formation that underlies the development area and consists of inclined strata that include relative low strength claystone interbeds that form planes or zones of weakness. Where inclined toward a free face, the earth material above these planes of weakness may move, or translate, in the direction of inclination (i.e. down-dip direction). Several landslides of this type have been identiﬁed within the Speciﬁc Plan area that are considered to be deep-seated translational landslides. Although most of the translational landslides appear to be ancient, a few are active. Surﬁcial failures are also common on the steeper slopes of the Speciﬁc Plan area (i.e. slope ratio less than 2 horizontal to 1 vertical). Mudstone or claystone interbeds in the Sespe Formation exposed on steep slopes are susceptible to shallow slumping when moisture contents approach saturation.

Shallow slumps high on slopes have resulted in local debris ﬂows. Numerous debris ﬂows were observed after the unusually heavy rainfall in February 1998.

Slopes, particularly dip slopes, formed of claystone or mudstone exhibit soil creep.

Within the Speciﬁc Plan area, erosion of sandstone bodies, particularly on scarp slopes (anti-dip slopes) has locally resulted in very steep slopes. Rock topples or falls have occurred on these slopes, particularly where sandstone is fractured.

Topples and falls were widespread on very steep slopes as a consequence of the 1994 Northridge earthquake. Shallow rockslides occurred on Whiteface associated with the main shock and aftershocks of the 1994 Northridge earthquake that resulted in rock avalanches and large dust clouds.

Within Dry and Tapo Canyons is located on the southeastern ﬂank of the east-west trending Santa Susana Mountains, a part of the Transverse Ranges Geomorphic Province. The Simi Anticline sub-parallels the southern Dry and Tapo Canyon property boundary. Bedding north of the anticlinal axis dips moderately to the north-northwest and on the southern limb of the anticline, bedding dips south-southwest. Numerous translational landslides are mapped on the north facing slopes of the ridges north of the Simi Anticline and on the southern slopes of the Simi Anticline. The majority of the site is under-lain by Tertiary non-marine sedimentary rocks of the Sespe Formation. Tertiary Llajas Formation, which unconformably underlies the Sespe Formation, outcrops in the extreme southeast portion of the site and the Monterey Formation is mapped unconformably on top of the Sespe in the northern portion of the site. The Sespe, Llajas, and Monterey Formations are overlain by surﬁcial units including landslides, alluvium, colluvium and artiﬁcial ﬁll.

Numerous landslides have been identiﬁed and conﬁrmed, through recent and past exploratory borings within Dry and Tapo Canyons. As shown in the geotechnical report prepared for the Lost Canyons project (Paciﬁc Soils, June 2007), several of the landslides have been identiﬁed as potentially hazardous and require remedial grading in order to stabilize the speciﬁc slopes. These include areas above and below residential pad areas.

The site geologic structure is dominated by the east trending Simi anticline.

Bedding dips moderately to the northwest on the northern limb of the anticline and to the south – southwest on the southern limb. The axis of the gently westward plunging anticline traverses the southern portion of the site and becomes less deﬁned toward the southeastern portion of the property. Folding August 2026 - II.

along the Simi anticline becomes more complicated in this area and breaks into several small east-trending anticlines and synclines.

No known active fault zones have been identiﬁed in Dry or Tapo Canyon; however, the Simi-Santa Rosa Fault Zone is mapped just to the south of the Speciﬁc Plan area. Other faults in the vicinity include the Santa Susana, Oak Ridge, Red Mountain-San Cayetano, and Northridge Faults.

The geotechnical report prepared for Dry and Tapo Canyons (Paciﬁc Soils, June 2007), demonstrates that portions of the Lost Canyons project site have been placed in a zone of required investigation for liquefaction potential, as well as earthquake-induced landslide potential, by the California Geological Survey (Seismic Hazards Map, Simi Valley East Quadrangle). Proposed development areas within the limits of these zones will require analysis and possibly remedial grading to mitigate these issues.
c. Vegetation
According to Biological Reports prepared by Envicom Corporation and Glenn Lukos and Associates, dated November 1998, for the Sand Canyon portion of the Speciﬁc Plan Area, the study area is characterized by a mix of Chaparral, Coastal Sage Scrub, non-native grassland, and oak woodland. Southern Coastal Live Oak Riparian woodlands, Southern Arroyo Willow Scrub, mule fat scrub, alluvial scrub and Athel Windrows are found adjacent to the seasonal drainages.

Within Dry and Tapo Canyons, a total of 10 different vegetation communities were identiﬁed on site. In particular, the coastal sage scrub communities occur as 12 different dominance associations. The primary vegetation communities present on site include Coastal Sage Scrub, Artiﬁcial Wetland, Coast Live Oak Woodland, Eucalyptus Woodland, Non-native Annual Grassland, Perennial Grassland, Quailbrush Scrub, Riparian Scrub, Southern Willow Scrub, and landscaping.

Details of each of the vegetation associations identiﬁed on site and an illustration of their distribution are provided in the appended report. A complete report of the rare plant surveys conducted on site is provided under separate cover.

The goal of the Speciﬁc Plan is to preserve, to the greatest extent possible, the Southern Willow Scrub, the Southern Coast Live Oak Riparian forest, and the Coastal Sage Scrub, Riparian Scrub, and perennial grassland which are considered sensitive habitats (see Exhibit #7, Conservation Map). Landscaping with non- invasive, native plants occurring in local vegetation communities will minimize long-term impacts to downstream waterways and adjacent sensitive habitats. d. Drainage Patterns
The Whiteface Speciﬁc Plan site generally drains in a southern direction, The Whiteface Speciﬁc Plan site generally drains in a southern direction, with existing storm drain structures in Erringer Road, Sycamore Drive and Tapo Canyon Road collecting the runoff at the project’s lowest elevations.

Sheet runoff is joined within a multitude of drainage rivulets that traverse the hillside slopes. These tributaries enter into the three major canyons that traverse the project site.

[27]
34 Ord. No. 1374
It is anticipated that the Whiteface Speciﬁc Plan development will drain into detention and downstream facilities that are identiﬁed in the City’s Master Plan of Drainage. The City and the Ventura County Watershed Protection District will determine the size of the facilities and the downstream discharge. e. View
Big Mountain and the sheer topographic front of the Whiteface escarpment are the prominent elements in the landscape viewed from the Valley ﬂoor. Big Mountain forms the northern horizon for most Simi Valley residents. The ridges that form the lower foothills to Big Mountain can be viewed from selected vantage points in the hills that rim the Valley. Within the Speciﬁc Plan area, north-facing views are dominated by Whiteface and the foothills rising up to Big Mountain. A signiﬁcant portion of the Sand Canyon area leading up to Big Mountain will be dedicated to the Rancho Simi Recreation and Park District for preservation as undeveloped open space during the Big Sky Ranch development (Sand Canyon).

Residential development, roads, and the proposed public park within Sand Canyon may have limited intrusion into areas with gradients of greater than 20 percent (20%). These encroachments will be as allowed by the Hillside Performance Standards (Municipal Code Section 9-32.010 et seq.). The Speciﬁc Plan compliant incursions within the Speciﬁc Plan boundary will be screened by the natural topography of the site and will not be visible from viewpoints along the Valley ﬂoor. Residential development will conform to the Ridge Line Development standards and Hillside Performance standards
f. Archaeology
There are eight (8) known archaeological sites within the Sand Canyon portion of the Speciﬁc Plan area. All sites were test excavated by Ancient Enterprises. A Cultural Resources Management Program for the Sand Canyon portion of the Whiteface Speciﬁc Plan area has been prepared to determine the appropriate action to be taken at each of the sites.

A number of surveys were conducted in Dry and Tapo Canyons with the most recent research investigations conducted in August 2006. State law prohibits the public disclosure of the speciﬁc location of archeological sites.

There are seven (7) archaeological sites recorded within the project boundaries of Dry and Tapo Canyons. All of the sites have been evaluated by State-certiﬁed archaeologists and were found to be “not signiﬁcant”. Because of those determinations, no additional studies will be required for the sites. In addition to the archaeological sites, nine (9) isolated occurrences of prehistoric artifacts were also recorded.

35 Ord. No. 1374
Because of the potential for buried archaeological material to be located within Dry and Tapo Canyons, it is recommended that a qualiﬁed archaeologist monitor any future ground-disturbing activities in native soils/sediments. In the event that archaeological resources are discovered during construction, the monitor will be empowered to temporarily halt or divert construction in the immediate vicinity of the discovery while it is evaluated for signiﬁcance. Construction activities could continue in other areas. If the discovery proves to be signiﬁcant, additional investigation, such as evaluation and data recovery excavation, may be warranted. g. Paleontology
The Tertiary sedimentary rocks exposed in Sand Canyon contain fossils, the evidence of ancient life. Fossil frogs, turtles, lizards, snakes, birds, opossum, insectivores, rodents, carnivores, tapir, a mastodon and other animals have been collected from Sespe Formation within the Speciﬁc Plan area. Qualiﬁed paleontologists should recover fossils exposed during the grading operations to mitigate damage to these non renewable cultural resources.

A number of surveys were conducted in the Dry and Tapo Canyon areas with the most recent research investigations conducted in August 2006. State law prohibits the public disclosure of the speciﬁc location of Paleontological sites. The majority of the proposed development in the Lost Canyons Project Site occurs in areas of Low Paleontological sensitivity, which is predominately comprised of Alluvium geological formations. The implementation of proper mitigation measures, as identiﬁed in the project’s CEQA documentation, can reduce the impact to any potential Paleontological resources to below the level of signiﬁcance.

B. Circulation
(See Exhibit #5: Overall Circulation and Volume I, Exhibit #21: Off-site Improvements) The Speciﬁc Plan area is accessible by three (3) secondary arterial roadways, First Street, Erringer Road and Tapo Canyon Road (south of Speciﬁc Plan boundary) and two (2) minor arterial roadways, Lost Canyons Drive and Tapo Canyon Road (between south Speciﬁc Plan boundary and approximately 190 feet north of Lost Canyons Drive). Each of these (with the exception of Lost Canyons Drive) intersects with State Route 118 south of the project area. Lost Canyons Drive, Madera, Erringer, and Tapo Canyon Road (south of Speciﬁc Plan boundary) are all identiﬁed as scenic roadways by the General Plan. The General Plan notes that the design of the road section of Lost Canyons Drive will be reviewed and/or modiﬁed during the review of the Big Sky Ranch (Whiteface) Speciﬁc Plan. This review was completed and this road was approved by the City Council with a changed classiﬁcation to a minor arterial roadway in December 2001. The general alignment of these roadways has been reﬁned based upon topography and land use design to reduce the intrusion of the roads on the adjacent hillsides, thereby reducing the hillside grading that would be required as a result of the roads’ construction.

All of these arterial roads will be designed with left and right turn lanes and bus turnouts at all intersections, as required by the Director of Public Works, along with traffic signals at major intersections, as conditioned for each tract map prior to recordation.

1. Madera Road
(See Volume I Exhibits #22 and #71, Public Street Sections) Madera Road follows the base of the foothills rising up to Whiteface, intersecting with Erringer Road 400 feet easterly of the westerly project boundary of Sand Canyon. The Circulation Element, page 7.16, of the City of Simi Valley General Plan delineates Madera Road as a secondary arterial roadway as well as a scenic roadway within the hillsides north of the Valley Floor. Madera Road connects to Lost Canyons Drive at Erringer Road within the Speciﬁc Plan boundary. The City Council designated Lost Canyons Drive as a minor arterial as part of a Speciﬁc Plan Amendment approved in December 2001.

Enriched parkways along Lost Canyons Drive will be designed to provide a landscaped and scenic atmosphere as the road is driven.

2. Lost Canyons Drive
(See Volume I Exhibit #22a, Public Street Sections)
Lost Canyons Drive provides access from the easterly terminus of Madera Road at Erringer Road to Tapo Canyon Road. This road is designated in the City’s General Plan as a Minor Arterial Road and as a Scenic Roadway. Lost Canyons Drive is responsive to the City’s Hillside Performance Standards and General Plan goals and policies, which desire a rural appearance in outlying areas while minimizing grading of hillsides. Accordingly, overall right of-way widths have been reduced from the secondary arterial standards, which were previously designated for this road. The City adopted the Minor Arterial designation to achieve this width reduction.

The resulting road has less grading than would typically be required for a minor arterial within the Valley ﬂoor. Enriched parkway requirement ends at the easterly boundary of Tract 5182 to Tapo Canyon Road. The width of the road varies throughout the Speciﬁc Plan area, reducing in width as the road turns easterly from residential to open space.

3. First Street
(See Volume I, Exhibit #22, Public Street Sections)
The future easterly extension of First Street will transition from its current terminus in a ninety degree direction towards Erringer Road, and will eventually connect with the completed segment of First Street that intersects with Erringer Road within Tract 5182-C that was re-named to Falcon Street. This extension and connection will provide additional access to State Route 118 for the residents of the project area, and will be developed by others as required in providing access for new development areas to the west.

4. Erringer Road
(See Volume I, Exhibit #22, Public Street Sections)
Erringer Road is a designated secondary arterial roadway with a 99-foot right-of-way according to the Simi Valley General Plan. From its fully improved terminus at State Route 118 interchange, the Erringer Road extension has been improved in a northerly direction to the intersection with Madera Road/Lost Canyons Drive. Erringer Road intersects with Falcon Street (formerly First Street) approximately 1,000 feet easterly of the westerly project boundary, and 600 feet northerly of the southerly project boundary.

Erringer Road is identiﬁed as a Scenic Roadway north of First Street in the Circulation Element of the Simi Valley General Plan, but is proposed to be improved as a secondary arterial due to anticipated ultimate traffic volumes.

5. Tapo Canyon Road
(Exhibits #15, #16 and #17, Tapo Canyon Road Street Section) From 500 feet north of Presidio Drive, to the planning boundary 190 feet north of Lost Canyons Drive, Tapo Canyon Road is set forth in the General Plan as a Minor Arterial, and will provide access to the project at the eastern boundary. Lost Canyons Drive will meet the proposed alignment approximately 2,900 feet north of Presidio Drive, or 2,300 feet from the southern property boundary. Tapo Canyon Road continues to go north and provides access to the Gillibrand Rock operation.

Tapo Canyon Road north of Presidio Drive is to be improved to the standards of a Minor arterial between Presidio Drive and Lost Canyons Drive. North of Lost Canyons Drive, Tapo Canyon Road will be left in its existing two (2) lane, paved condition. An alignment study has been completed for Tapo Canyon Road from Presidio to the city limit at Bennet Road, and the right-of-way dedication requirements have been offered (See Chapter III, Section G, Infrastructure, 1. Vehicular Circulation for more detailed discussion related to the Lost Canyons project area).

C. Infrastructure

1. Purveyors
Necessary infrastructure and public services will be supplied to the Whiteface Speciﬁc Plan area by the following agencies:

Water Ventura County Waterworks District No. 8
Sewer/Reclaimed Water 1 City of Simi Valley Sanitation Services Division Storm Drain/Flood Control Ventura County Watershed Protection District Electricity Southern California Edison
Gas Southern California Gas Company
Telephone Paciﬁc Bell
Police City of Simi Valley
Fire Ventura County Fire Protection District
Schools Simi Valley Uniﬁed School District
Parks Rancho Simi Recreation and Park District
Refuse Waste Management
Cable Television Time Warner Cable

1. Should reclaimed water become available by the City, the Whiteface Speciﬁc Plan will be required to join a reclaimed water system when it is economically feasible and once it is implemented by the Ventura County Waterworks District No. 8.

2. Water Services
The Whiteface Speciﬁc Plan is divided into two primary water pressure zones and will be served by a total of two potable water tanks. One potable water tank is proposed within the Lost Canyons development and the other is an existing tank is located in Sand Canyon. Architectural treatment or other treatment such as landscaping berms and natural contours will aid screening of the proposed tank and minimize visual impacts upon the development areas. A detailed Water Master Plan has been completed for the Lost Canyons Speciﬁc Plan area.

The Lost Canyons Speciﬁc Plan Area is located within the service boundaries of the Ventura County Waterworks District No. 8 (the “District”). Water supply originates from the Calleguas Municipal Water District and is conveyed to the project site through the 1248 and 1355 pressure zones via several transmission lines of varying size. Water will be pumped to the existing 1355 Tapo Street Pump Station until the new Walnut pump station is complete. Water is further pumped through a new Lost Canyons booster station to the proposed Lost Canyons potable tank described above. The completion of the proposed water improvements will provide reliable water supply and service pressures.

III. Dry and Tapo Canyons
A. Introduction
Dry Canyon and Tapo Canyon, two neighboring valleys totaling 1,770 acres, located at the base of Big Mountain, are the proposed sites of a new community to be named Lost Canyons. The development of Lost Canyons is planned as a private community designed to provide a housing option not otherwise available within Simi Valley, while embracing and enhancing the unique topography of the area.

B. Lost Canyons Concept and Speciﬁc Plan Land Use
Categories
The plan, as shown in Exhibit #6 Land Plan and Canyon Boundaries, details where development will occur within the Speciﬁc Plan Boundary. The map establishes the Plan’s intent for site planning, land use designation, connectivity and preservation of open space. Conservation Map (Exhibit #7) for Lost Canyons prescribes the sensitive conservation of resources and consists primarily of open space, residential uses, and private recreation center.

The land uses establishes and description of plan layout and purpose are described below.

1. Residential Uses
Shown in Exhibit #6, Land Plan and Canyon Boundaries and Exhibit #13, Proposed Planning Areas, four (4) residential product types are contemplated in the Lost Canyons Project:
• Product A: 60 x 100’ Lots
• Product B: 65 x 100’ Lots
• Product C: 60 x 120’ Lots
• Product D: 90 x 110’ Lots
The Land Plan features the majority of development north of Lost Canyons Road, within in the north portion of Dry and Tapo Canyons as well as small pockets of development to the south (two lots). The clustering of development achieves the following:
• Reduces environmental impacts to the greater Whiteface hillsides by eliminating development in environmentally sensitive areas, • Creates a more sustainable plan by increasing use efficiency of public resources such as water and sewer,
• Reduces time and access constraints for safety services such as police and ﬁre,
• Increases the Plan’s economic feasibility to create new and needed housing in the area, and,
• Provides a connected neighborhood feel for future residents and homeowners.

August 2026 - III. Dry and Tapo Canyons
[37]
44 Ord. No. 1374
The residential development concept for the community is that most development occurs in a project core (Planning Areas 1-6) north of Lost Canyons Road. Planning Area 7 is zoned Residential Estate. Similarly, Planning Area 8 is reserved for open space. In Planning Area 9 it is expected that residential development would occur through two individual 90x110’ Product D lots, identiﬁed off Ditch and Anderson to the south. Finally, Planning Area 8 is zoned for open space. See Exhibit #12, Planning Areas on page 65.

The residential component of the Lost Canyons Project consists of a maximum of 364 residential dwelling units within Dry Canyon and Tapo Canyon located within the following residential categories.
a. Residential Estate
Residential Estate parcels are shown on Exhibit 9 General Plan Land Use Designations and Exhibit #11 Speciﬁc Plan Zoning. There are no units planned on residential estate lots. These lots provide a transition from the natural landscape to the medium and low density residential in the north, and to the south.

While there is no plan for development of these lots, they shall maintain a buildable pad of a minimum of 6,000 square feet on minimum 20-acre lots.

A signiﬁcant portion of the lot acreage within each of the estate lots shall be preserved in its natural state, with some limited boarding of horses only, pursuant to Sections 9-28.030 and 9-44.060 of the City of Simi Valley Development Code, and located in the (H) overlay zone, described below (see Exhibit #11, Speciﬁc Plan Zoning). Use of the land outside of the buildable pad shall be limited to passive uses in order to maintain a natural open space character, preserving the hillsides, and natural vegetation. If built at a later time, each home within an estate lot area shall allow for the location of accessory structures within the lot, so long as any accessory structure is located on a land area with a natural slope of less than twenty percent (20%). These portions of the Project Site will be kept, to the greatest extent feasible, in their natural state, free from intensive development activities so that residents can enjoy the natural surroundings.

The areas in the designated as residential estate are situated to protect the existing signiﬁcant Whiteface escarpment land form and adjacent ridgelines to the northeast that serve as a backdrop to not only the project development off Lost Canyon Drive, and the entire City of Simi Valley. To accomplish this aesthetic and buffer transition, portions of the hillsides outside the buildable pad within the natural open space areas are subject to a Conservation Mechanism as deﬁned below
i) Conservation Mechanism.

A Conservation Mechanism has been designed for the Lost Canyons Speciﬁc Plan to ensure preservation of open space and surrounding natural resources. The language below references Exhibit #7, Conservation Map.

Pursuant to the Lost Canyons Project Resource Agency permits received from the US Army Corps of Engineers, US Fish and Wildlife Service, California Department of Fish and Wildlife and California Regional Water Quality Control Board the August 2026 - III.

areas shown on the Conservation Map (Exhibit #7) will be preserved though conservation easements and deed restrictions. The Resource Agency permits require habitat restoration, monitoring and maintenance by the Project until the conservation easements can be turned over to a long-term manager.

The three (3) areas shown in blue are 1602 riparian conservation easements (CE’s) and the areas shown in light green are 404 Costal Sage Shrub (CSS) conservation easements. Additionally, as shown in the crossed hatched green color, a 404 CSS deed restriction will be recorded on these portions of the property.

Separately, restrictive covenants have been recorded against the areas shown in orange (RE lots), that require focused California Gnat Catcher surveys be performed and submitted to the USFW before disturbing the property.

Preservation of the Whiteface escarpment will be provided through a combination of conservation mechanisms and open space as set forth above. Access and uses will be restricted to retain the character of the preserved land. Public access to these areas will be addressed in the Conservation Mechanism(s). i) H (Horse) Overlay Zoning District
The Speciﬁc Plan’s H (Horse) overlay zoning district for the estate lots shall follow Sections 9-28.030 and 9-44.060, Horse (H) Overlay District of the City’s Development Code. This overlay permits the equestrian use because of the estate lot’s size and recognizes the compatibility of the use within the rural setting.

The purpose of the Speciﬁc Plan’s Horse Overlay district is intended to provide these large estate areas for the keeping of horses only. Proposed development and new land uses within the H overlay district shall comply with all applicable requirements of the primary zoning district.
b. Residential Low
Product D (90x110’) lots will be located within this category with not less than eighty percent (80%) of the lots being a minimum of 1/3-acre (14,520 square feet) in size. Residential Low lots are clustered primarily in the northeast and two lots to the south in Planning Areas 3 and 10 as shown on Exhibit #12, Planning Areas, with the majority located on the outermost edge of the clustered development pattern, enabling the homes with views of the hillside, creating an opportunity to maximize on the expansive open space character of the site. The clustering of the landscape plantings throughout the neighborhoods and streetscape shall complement the existing natural environment and to create a natural transition between the single- family neighborhoods and open space.

Product A: 60 x 100’ lots, Product B: 65 x 100’ Lots, and Product C: 60 x 120’ Lots will be located within this category as shown in Table III-2, Planning Area Statistical Table.

These homes are situated centrally to the project area, focusing on connected development that provides hillside views, access to trail’s and a high quality community experience. Exterior architectural details for these homes will vary, including material details, entries and doorways, hardscape, and landscape features. These exterior treatments provide unique transitions between homes, and when coupled with the latitude a purchaser is typically offered in the home’s interior, emulate a more “custom” experience. These products are an essential component of the Lost Canyons character and will establish the core and quality of the community.

2. Open Space Uses
A signiﬁcant portion of the Lost Canyons Project Site will remain natural, and is located within the Open Space category, located within Planning Area 9 as shown on Exhibit #12, Planning Areas, and Exhibit #10, Conceptual Open Space Plan. These Open Space areas encompass the open areas and vistas within the Lost Canyons Project Site. These portions of the Project Site will be kept in their natural state.

3. Lost Canyon Trails Plan
The Speciﬁc Plan preserves public access to several portions of the Whiteface Speciﬁc Plan Area through open space designation and community and public-access trails.

Community trails are permitted so that residents and the public can enjoy the natural surroundings. The community trails are accessed through the project area along the northern edge of development (as shown in Exhibit #8, Conceptual Trails Plan).

One trail head for public access will be provided, and will be located at Bennett Road on the northeastern portion of the Speciﬁc Plan area. Additionally, a space located off the entrance at Tapo Canyon Road and Lost Canyons Drive will be dedicated for a future RSRPD trail head. The Trails Plan creates multiple routes at easy to medium levels, the trails and vantage points. The trail system coordinates access for both natural and improved recreational areas in conjunction with the Rancho Simi Recreation and Park District Master Trails Plan. (See Exhibit #8, Conceptual Trails Plan.) Regional trails shall be maintained by the Rancho Simi Valley Recreation Park District and community trails shall be maintained by the HOA.
a. Open Space/Whiteface
A signiﬁcant portion of the Open Space will be preserved in its natural state. These Open Space areas encompass the natural areas and vistas within the Lost Canyons Project Site (see Exhibit #6, Land Plan and Canyon Boundaries, and Exhibit #10 Conceptual Open Space Plan). The open space areas are divided as follows:

Conservation of Natural Open Space. This includes signiﬁcant areas in Dry and Tapo Canyon and hillside areas throughout the plan. In order to enhance the protection of the Whiteface escarpment and other open space areas, the preservation of these areas will be subject to Conservation Mechanism(s) as discussed above. These open space areas or portion thereto may also be dedicated to the Rancho Simi Recreation and Park District, HOA or other land conservation entity. The Conservation Plan and mechanisms are shown in Exhibit #7.
b. Improved Open Space Areas/Trails (Public and Private) Dispersed throughout the Open Space areas of Lost Canyons will be a series of regional and community trails (see Exhibit #8, Conceptual Trails Plan). The public trails within Lost Canyons provide for development of the City’s regional trails system, and connectivity to and through the project. Access to the community trails is provided by a trail head at Bennett Road, and a future trail head for RSRPD at the intersection of Lost Canyons Drive and Tapo Canyon Road.

C. General Plan Consistency

1. Relationship to City’s General Plan
The goals of this Speciﬁc Plan include the provision for stewardship of the natural resources within the open space and to guide future development in conformance with the General Plan. The Speciﬁc Plan provides for the preservation of natural resources and the provision of recreational amenities in combination with residential neighborhoods that transition and interface with the existing adjacent neighborhoods. The Speciﬁc Plan balances the needs of the future residents with the existing residents in the community, and provides for logical growth in an area adjacent to existing public services and utilities.

The opportunity to realize the vision set forth in the planning documents for both Dry Canyon and Tapo Canyon can be accomplished working within the regulatory framework (with respect to the number of homes), as well as the environmental objectives (preserving the natural terrain) envisioned in the City’s General Plan and the Whiteface Speciﬁc Plan. Exhibit #9, General Plan Land Use Designations, presents the General Plan land use designation for the adopted Lost Canyons Project Area. The Speciﬁc Plan accomplishes these goals and includes the following:

1. Reallocate the combined residential density permitted within Dry Canyon and Tapo Canyon by using the previously graded areas of the golf course and other portions of the project site, in accordance with the Simi Valley Hillside Performance Standards to create up to 364 residential units, including but not limited to, Product A: 60’ x 100’ lots, Product B 65’ x 100’ lots, and Product C 60’ x 120’ lots, as well as the larger 90’ x 100’ lots of Product D. By primarily utilizing these existing developed areas for the new home sites the objectives of the Whiteface Speciﬁc Plan will be met by having minimal impact on the natural environment. The proposed reallocation will not increase the residential density contemplated by the General Plan.

2. Provide Community trails north of Lost Canyons Road with direct walking access to the community.

3. Provide RSRPD with a new trail alignment through Dry Canyons.

4. Rezone the Lost Canyons golf course and recreational commercial land for medium and low density housing in order to cluster development north of Lost Canyons Road. The clustering of development and the use of previously grade land for the golf course intends to reduce the environmental impacts to the surrounding hillside and retain the natural environments of Dry and Tapo Canyons.

5. Rezone the southern portion of the plan area (south of Lost Canyons Road in Dry and Tapo Canyon) from Residential Low to Residential Estate, reducing the development impacts of new housing and infrastructure in the southernmost area of the plan.

6. Change portions of the land use designations including changing the previous golf course to Residential Low and Medium, and portions of previous Estate Residential to Open Space. See Exhibit #9 General Plan Land Use Designations.

51 Ord. No. 1374
D. Speciﬁc Plan Objectives and General Plan
Implementation
The following Speciﬁc Plan Amendment objectives have been applied to the planning and design process for the Speciﬁc Plan Amendment. The Lost Canyons Speciﬁc Plan has been prepared to incorporate and advance the overall objectives of the City of Simi Valley General Plan. The Speciﬁc Plan Amendment sections that address the objectives follow.

1. Lost Canyons Speciﬁc Plan Objectives
a. Natural Resources within Preserved Open Space
i) Preserve a signiﬁcant portion of the Project Area, as open space and recreational uses.

The Lost Canyons Speciﬁc Plan Open Space (Exhibit #10) designates a signiﬁcant portion of Dry and Tapo Canyons as open space. These open space areas are distributed throughout the plan area to preserve sensitive habitat, increase scenic views and create a balanced development pattern.
ii) Provide for the preservation of Whiteface to preserve natural resources and scenic qualities.

The Lost Canyons Speciﬁc Plan Land Plan (Exhibit #6 Land Plan and Canyon Boundaries) designates a signiﬁcant portion of the project area for open space and recreational uses. The area of Whiteface falls within the Residential Estate areas, and a Conservation Mechanism (See Exhibit #7 Conservation Map) will be placed on these large lots to ensure the preservation of Whiteface. Private preservation of the Whiteface escarpment is preferred because it will provide a greater degree of control over those portions subject to conservation. Access can be restricted rather than open, allowing for more diligent monitoring of the preserved land. iii) Provide for the preservation and/or restoration of wetland and riparian areas.

The Lost Canyons project calls for the preservation of a signiﬁcant amount of open space and recreation areas as shown on Exhibit #10, Conceptual Open Space Plan. Among this acreage (as shown in Exhibit #7, Conservation Map) 1602 Riparian CE Area includes drainage corridors which are under the jurisdiction of the United States Army Corps of Engineers and the California Department of Fish and Game, including the alkaline marsh area south of Lost Canyons Drive. iv) Respect the panoramic, visual, and aesthetic resources of the Speciﬁc Plan Area and surrounding region.

The Lost Canyons Speciﬁc Plan Open Space Exhibit #10 designates a signiﬁcant amount of the project area for open space and recreational uses. Portions of this preserved open space include the prominent hillsides and ridgelines that characterize the Lost Canyons area. The Lost Canyons project also includes a landscape concept plan that emphasizes the blending of development with the natural character of the surrounding area, in order to preserve the inherent, aesthetic nature of the project’s surrounding area.

August 2026 - III. Dry and Tapo Canyons
[45]
52 Ord. No. 1374
v) Protect sensitive habitat areas by relocating future residential development from the southern portion of the plan area (south of Lost Canyons Road) to areas that were previously used for golf course recreation, north of Lost Canyons Drive.

The Lost Canyons Land Use Plan (Exhibit #6 Land Plan and Canyon Boundaries) protects sensitive habitats and drainage/riparian areas. Residential development within Lost Canyons is relocated from natural and undisturbed land to the previous location of the golf course facilities, north of Lost Canyons Road. b. Recreational Amenities within Open Space
i) Provide accessibility to the open space, via a network of paths and multi-use trails with connections to existing paths and trails.

The Lost Canyons Project provides for public access to areas designated open space. Residential areas within the project contain a system of improved community trails that link to existing unimproved paths and service access roads.

Additionally, there are regional multi-use trail connections planned throughout the Speciﬁc Plan area, including a future Rancho Simi Parks and Recreation District trail head location east of Tapo Canyon Road, at Lost Canyons Drive intersection. ii) Establish pedestrian, bicycle and equestrian paths and trails for usage by the public with linkages to the adjacent existing neighborhoods and connections to existing paths and trails.

The Lost Canyons project establishes provisions for the creation of an integrated trail system, as shown on Exhibit #8, Conceptual Trails Plan. This plan contains linkages between proposed residential development and existing and proposed trails.
ii) Provide a public trail head to provide public access to the trails systems and provide a trail alignment for RSRPD for future regional trails.

The Lost Canyons project will provide a trail head off Bennett Road that will connect the pedestrian, community trails in the northern portion of the plan area.

Additionally, the plan will dedicate an easement for a future trail head at Lost Canyons Drive and Tapo Canyon Road as well as dedicated trail alignments for the Dry Canyon Trail as well as other regional, multi-use trails in the future. c. Community Planning
i) Minimize the modiﬁcations of the existing landforms using clustered development techniques to achieve sensitive development patterns.

Residential development within Lost Canyons is clustered within the area where a golf course was previously developed and graded (north of Lost Canyons Drive), and where the visual impacts of development on the surrounding hillsides and canyons are minimized. This clustering results in a designation of a signiﬁcant portion of the project area’s 1,770 acres for open space and recreation uses.

This open space includes an assortment of prominent natural features, including hillsides and ridgelines, and drainage/riparian areas.

[46]
53 Ord. No. 1374
ii) Locate development adjacent to existing infrastructure in order to minimize the extension of public services and utilities.

The Lost Canyons project locates the majority of development activities within the central portion of the Project Site, either contiguous to or in close proximity to existing infrastructure.
iii) Design a community that results in a compatible transition to the existing adjacent residential neighborhoods.

The Lost Canyons project utilizes both sensitive landscape techniques and the clustering of development within areas previously altered by golf course construction to create a natural transition between existing and proposed development. The Landscape Architecture Guidelines within Appendix A, Lost Canyons Design Guidelines, focuses on gently transitioning residential development into open space portions of the project site. Development is located in a manner to preserve hillsides and ridgelines, thus preserving views for both future residents of the project and those residents in adjacent neighborhoods. iv) Establish a maximum Development threshold of 364 residential units for the Speciﬁc Plan Area.

The Lost Canyons project allows for a maximum of 364 residential units within the Project Site. While the project does provide ﬂexibility through its implementation program by allowing a relocation of the total number of residential units allowed in each of the Planning Areas, it nevertheless maintains the 364-unit threshold. v) Provide for a variety of lot sizes, in a conﬁguration consistent with the City’s Residential Design Guidelines.

The Lost Canyons Project allows for a variety of residential lot sizes, ranging from large, 20+ acre Estate Lots, to 90x110’ lots with no less than eighty percent (80%) of the lots being a minimum of 1/3-acre (14,520 square feet) in size (Product D), to smaller single-family detached lots (Product A, Product B and Product C lots) of a minimum 6,000 square feet in a conﬁguration consistent with the City’s Residential Design Guidelines.
vi) Coordinate with service providers and applicable public health and safety agencies to facilitate extension of the adequate coverage of existing local Public Safety Communication Systems within the proposed development area in order to provide essential services to the community.

The Lost Canyons geography contains several constraints to the coverage capabilities of existing communication systems utilized by public health and safety agencies, including but not limited to, Police, Fire, Water, and Sanitation agencies.

These constraints and corrective measures shall be addressed in the subsequent tentative tract map and planned development design of Dry and Tapo Canyons in accordance with Federal and State Law, the City of Simi Valley Municipal Code and this Speciﬁc Plan.

August 2026 - III. Dry and Tapo Canyons
[47]
54 Ord. No. 1374
d. Housing
i) Provide residential development in response to the current and future demand for housing within the region.

The Lost Canyons Project allows for up to 364 single-family dwelling units on approximately 1,770 acres within Dry and Tapo Canyons (Lost Canyons). The Land Use Plan allows for a variety of single-family residential lot sizes, ranging from 60x100’ to 90x110’ lots.
ii) Provide an upscale housing option which is otherwise limited in the City of Simi Valley.

The Lost Canyons Project anticipates providing up to 364 single family, detached homes and homesites. The intent is for the Project to enhance the existing residential market within the City of Simi Valley by producing a new concept which does not currently exist as a lifestyle choice within the City.

2. General Plan Elements
The Speciﬁc Plan Amendment implements the following goals of the Simi Valley General Plan:
a. Land Use Element
GOAL LU-1: Growth and Change. Sustainable growth and change, achieved through orderly and well-planned development, meet the needs of existing and future residents and businesses, ensure the effective and equitable provision of public services, and efficiently use land and infrastructure.

The Lost Canyons Project is a new master-planned private community in Dry and Tapo Canyons. It will provide new housing opportunities in the City of Simi Valley for existing and future residents, preserve and conserve open space, while enhancing the unique topography of the area. The land use plan, as shown in Exhibit #6 Land Plan and Canyon Boundaries, establishes the site planning for the Project. Subsequent exhibits in the Speciﬁc Plan show the provisions for public services and infrastructure.

The Project will have an internal circulation network, multi-use trails network, recreation center, and a scenic lake that will serve as a ﬁre emergency, water storage area. Development will primarily be clustered in the area north of Lost Canyons Road, within the north portion of Dry and Tapo Canyons. The Project will respect Simi Valley’s natural setting by eliminating development in environmentally sensitive area; provide a circulation network that supports walking, biking, and other modes of transportation; and have a community gathering space for residents to recreate and socialize.

August 2026 - III. Dry and Tapo Canyons Whiteface Speciﬁc Plan Volume II - Lost Canyon
[48]
55 Ord. No. 1374
GOAL LU-4: Development Shaped by Environmental Setting. Development is located to respect, work with, and complement the natural features of the land.

The Lost Canyons Project is planned and designed to complement the natural features of the Whiteface Escarpment and the Santa Susana Mountains. Residential development is clustered around the project core.

With the clustered development approach, a signiﬁcant portion of the Lost Canyons Project Site will be conserved and preserved as open space, as shown in Exhibit #12, Planning Areas, and Exhibit #10, Conceptual Open Space Plan. A Conservation Mechanism has been designed for the Lost Canyons Speciﬁc Plan to ensure preservation of open space and surrounding natural resources, as shown in Exhibit #7, Conservation Map.

GOAL LU-7: Viewsheds. Vistas of the hillsides, valley ﬂoor, city entrance areas, recreation areas, major open space areas, and viewsheds from the hills are maintained for the public.

The viewsheds are one of the most cherished features in the Project. As such, the residential development pattern, with the clustered development approach, is designed to complement the natural features of the land and minimize impacts to natural vistas and slopes.

GOAL LU-10: Livable and Quality Neighborhoods. A city composed of neighborhoods with a variety of housing types, densities, and design, and that provide a mix of land uses, services, and amenities that support the needs of its residents.

The Lost Canyons Project will be a new neighborhood that offers residents a variety of housing options in different densities and designs. Four residential product types are contemplated in the Project: Product A: 60 x 100’ lots, Product B: 65 x 100’ Lots, Product C: 60 x 120’ Lots , and Product D: 90’ x 110’. In addition to residential uses, Lost Canyons will feature a scenic lake and recreation center that support the recreation needs of residents.

GOAL LU-12: Neighborhood Identity. Residential neighborhoods are provided that are distinctly identiﬁed and differentiated from one another in consideration of geography, character, and lifestyle.

Neighborhood identity will be achieved through a variety of architectural and landscaping elements. Building setbacks would be typically kept to a minimum to create a more deﬁned space, and building massing and height would be allowed to vary to encourage prominent architectural accent buildings. Project entries, landscaping, and signage and monumentation will deﬁne and communicate the street character to residents and visitors. The Design Guidelines and Program Book contains more information on how to achieve a neighborhood identity in the Lost Canyons Project.

August 2026 - III. Dry and Tapo Canyons
[49]
56 Ord. No. 1374
GOAL LU-32: General Plan and Zoning Consistency. Development proposals within the city are consistent with the General Plan Policies and Land Use Designations identiﬁed on the General Plan Land Use Map.

This Speciﬁc Plan functions as the zoning ordinance for the Project Area. The provisions of this Speciﬁc Plan Amendment are consistent with the Land Use policies and designations set forth in the General Plan.

GOAL HR-1 Historic Resources. Historically signiﬁcant landmarks, sites, natural features, and structures are recognized and protected.

Signiﬁcant archaeological and historical features, if discovered within the Lost Canyons Project Area during monitored earth moving activities, should be excavated and collected following typical mitigation measures and conditions of approval as prescribed by the Project entitlements, and environmental determination.

GOAL EJ-2: Land Use Decisions. Land use decisions do not adversely impact disadvantaged individuals and groups differently than the population as a whole.

The Lost Canyons Project will be a new planned development that will expand housing opportunities in Simi Valley. As such, it will not adversely impact disadvantaged individuals or groups currently residing in the city. b. Natural Resources Element
GOAL NR-1: Natural Resource Conservation. Natural resources of importance to the City of Simi Valley and its Planning Area are conserved, enhanced, and protected.

The Lost Canyons land use plan (Exhibit #6 Land Plan and Canyon Boundaries) and Conceptual Open Space Plan (Exhibit #10) provide for the permanent preservation of Whiteface, a unique portion of the Project Site and the City’s overall character. Natural resources, including hillsides, wetlands, and oak woodlands will be preserved to the maximum extent feasible. There is a signiﬁcant amount of open space area that allows for the conservation and protection of the site’s natural resources.

GOAL NR-2: Vegetation and Habitat Preservation. Plant and wildlife habitat are preserved and enhanced and wildlife movement corridors are protected.

The Lost Canyons land plan (Exhibit #6 Land Plan and Canyon Boundaries) and Conceptual Open Space Plan (Exhibit #10) provide for large, contiguous open space areas that preserve existing plant resources, wildlife habitats, and wildlife movement corridors. Drought-resistant and native vegetation is utilized in Project landscape areas appropriate to the region in transition areas between development and open space uses. In addition, the project is subject to the standards in the Ventura County Fire Department Fuel Modiﬁcation and the Fire Prevention Protection Plan.

August 2026 - III. Dry and Tapo Canyons Whiteface Speciﬁc Plan Volume II - Lost Canyon
[50]
57 Ord. No. 1374
GOAL NR-3: Visual Resource Protection. Signiﬁcant visual resources are preserved as important quality-of-life amenities for residents and as assets for recreation and tourism.

The Lost Canyons land use plan(Exhibit #6 Land Plan and Canyon Boundaries) protects prominent ridgelines and unique natural land features and enhances the new community by maintaining the open character of the hillsides. The hillsides should be protected by locating residential development primarily within the previously disturbed areas of the Project Site.

GOAL NR-4: Water Conservation. Water consumption is minimized through conservation methods and other techniques.

The Project will have several water-conserving measures, including the use of drought-tolerant plant species and efficient irrigation systems. Reclaimed water is not anticipated for use in the landscaped area. The landscape areas adjacent to open space will be revegetated using a drought-tolerant plant palette, which would reduce the need for supplemental irrigation water and utilization of non- potable water service.

GOAL NR-9: Air Quality. Air Quality in the City and the Simi Valley environs is improved.

The extension of public bicycle lanes, pedestrian and multi-use trails into and through the Lost Canyons Project to service its residents encourages bicycle riding as an alternative transportation mode. Additionally, the clustering of residential uses will encourage walking and other forms of non-vehicle transport such as biking. The applicant should coordinate with the City on innovative methods to minimize adverse air quality impacts associated with construction impacts.
c. Housing Element (as revised 2023)
HOUSING ELEMENT GOAL 1: Balance Community. A balanced community with services and housing opportunities is created for all.

The Lost Canyons Project envisions the creation of a uniﬁed “neighborhood” within each of the Planning Areas, and a feeling of “community” within the Project Site as a whole. A variety of housing types and lot sizes are planned to appeal to a diverse range of family types and income levels. As mentioned earlier in section D.1.d. Housing, of this Speciﬁc Plan, Lost Canyons provides a range of lots and product types from smaller lot Product A: 60 x 100’ lots and Product B: 65 x 100’ Lots, to larger lot Product C: 60 x 120’ Lots and Product D: 90 x 110’ lots – each adding to the balance of housing product opportunity for new families, homeowners and residents as well blending together to create a connected community feel.

August 2026 - III. Dry and Tapo Canyons
[51]
58 Ord. No. 1374
HOUSING ELEMENT GOAL 2: Existing Housing Stock. The existing residential housing stock is maintained and improved where necessary.

Currently there are no existing homes in the Lost Canyons project area, with the exception of one existing residence on the northeastern edge of the Plan Boundary, which is grandfathered in as an existing residential land use. This Speciﬁc Plan Amendment will not displace existing residential stock. The Lost Canyons project, however, will provide a comprehensively designed development plan that allows ﬂexibility for development of a maximum of 364 residential dwelling units. The private, gated community consists of a mix of lots ranging from 60x100’ to 90x110’ with potential equestrian use.
d. Community Services Element
GOAL PR-1: Parks and Recreation Facilities. Parks, recreation, and community facilities that enhance community livability and contribute to public health are available to serve the diverse recreational needs of residents and visitors.

The Lost Canyons Project provides exceptional opportunities for low-intensity outdoor recreational activities and establishing passive recreational areas. The character of the new community is based on, and enhanced by, the compatible integration of development with the natural scenic features that contribute to Lost Canyons’ most deﬁning attributes.

GOAL PR-2: Recreational and Leisure Programs. Recreational programs and services are provided that promote personal enrichment, healthy lifestyles, wellness, fun, lifelong learning, skill development, and positive relationships.

A private recreation center is proposed for Planning Area 6. Located next to the lake, the recreation center will offer a variety of amenities to residents to take part in a multitude of active and passive activities.

The Lost Canyons Project will have an accessible and connected trails network for future residents and Simi Valley community members to use. A dedication will be provided for a future trail head for Rancho Simi Recreation and Park District to provide access to its trail system.

Additionally, a trail head will be provided off of Bennett Road, providing access at the northern portion of the trails. The Conceptual Trail Plan allows access to Whiteface and connection to trails within the City’s Master Plan of Trails.

59 Ord. No. 1374
e. Mobility and Infrastructure Element
GOAL M-1: Safe and Efficient Transportation System. The safe and efficient movement of people, goods, and services is provided by encouraging the design, construction, and maintenance of an integrated mobility and circulation system, including roads, transit, bike paths, sidewalks, and commuter rail.

Lost Canyons will have an integrated network roadway that supports the movement of people, goods, and services. The majority of the Project’s residential circulation movement utilizes ingress and egress via Tapo Canyon Road and Lost Canyons Drive. Residential neighborhoods will be accessed through collector and local streets deemed acceptable by the City. The circulation network will have tree-lined streets that provide a comfortable pedestrian experience.

Roadways will be designed according to City standards. Streets may incorporate passive traffic calming devices such as landscape islands. Actual street routing and design speciﬁcations are addressed in the Circulation section of this Chapter.

GOAL M-4: Level of Service. Efficient movement of vehicles, people, and other modes of travel along City streets is provided by maintaining acceptable levels of service at intersections.

The circulation network in the Project will be designed to meet the Level of Service requirements as required in the General Plan, Mobility and Infrastructure chapter.

GOAL M-9: Neighborhood Traffic Control. Community character and quality of life are maintained in City neighborhoods through the implementation of neighborhood traffic management techniques.

The Lost Canyon Project will have an internal circulation comprised of private streets and driveways. The private roadways will be built as low speed, pedestrian- friendly streets through the Project, around the Village Core area, and to the home sites, and will serve to calm traffic throughout the neighborhood.

GOAL M-12: Bicycling as a Travel Mode Option. Develop bicycle facilities and programs in Simi Valley by providing an integrated, complete, and safe bicycle system and encourage bicycling as a viable option to automobile travel.

Bicycle lanes along Tapo Canyon Road and Lost Canyons Drive are provided, and a project adjacent bus stops allows for access to the plan area via alternative travel methods.

August 2026 - III. Dry and Tapo Canyons
[53]
60 Ord. No. 1374
GOAL M-14: Pedestrian Travel. A safe and comfortable pedestrian environment is provided that results in walking as a desirable travel choice, particularly for short trips, within the City.

The Lost Canyons Project will have a trails network comprised of regional and community trails. Within the developed portion of the Project Site, trails would provide access to the Rancho Simi Recreation and Park District’s east- west trail linkages and the Whiteface escarpment. Meanwhile, the regional trail system connects to a community residential trail system, linking the various neighborhoods to the development along Lost Canyons Road.

GOAL IU-1: Reliable Water Supply. A high-quality water supply, water treatment, distribution, pumping, and storage system that is reliable for meeting the current and projected future daily and peak water demands of Simi Valley residents is provided for the community.

The stormwater detention facility and common area irrigation lake will continue to serve as a ﬁre emergency, water storage area located in the central portion of the Project Site. This source and the water system designed for the Project provides adequate supply to Lost Canyons’ residents.

GOAL IU-3: Service for Current and Future Development. A sewer collection and treatment system that supports existing and planned development is provided that minimizes adverse effects to water quality.

A Conceptual Sewer Plan is provided for the Project and is designed to provide a level of service consistent with the master plan for the anticipated population and land uses.

GOAL IU-4: Drainage Facilities. Adequate stormwater drainage facilities and services are available that are environmentally sensitive, accommodate growth, and protect residents and property.

A Drainage Study for the Project includes drainage facilities necessary to meet the requirements of the City of Simi Valley Master Plan of Drainage, the Ventura County Watershed Protection District, and other applicable Regulatory agencies.

In addition, National Pollutant Discharge Elimination System (NPDES) facilities will be provided to ensure the quality of runoff water. NPDES permits will be obtained for both the construction and ultimate development phases. Best Management Practices will be incorporated into the development and ﬁnal design of drainage facilities should be proposed and reviewed as part of subsequent plan approvals (e.g., Final Tract Maps).

GOAL IU-5: Solid Waste Facilities. Solid waste facilities that meet or exceed requirements of state law, and utilize strategies for economic and efficient collection, transfer, recycling, storage, and disposal of refuse are provided.

Solid waste recycling, reuse, and disposal will be available to Lost Canyon residents. The HOA will be responsible for coordinating solid waste pickup with the City’s refuse purveyor to ensure the health and safety of community members.

GOAL IU-6: Reliable Energy Resources. Affordable, reliable, and environmentally sensitive energy resources are available for the City’s residents and businesses.

The applicant will coordinate with Southern California Edison and the Southern California Gas Company to provide electricity and gas for future residents, along with the necessary infrastructure to meet the project’s needs as well as city and state regulations.

GOAL IU-7: Telecommunications Infrastructure. Provision of adequate, safe, innovative, and aesthetically designed telecommunication infrastructure to support existing and future land uses is provided within the City.

The applicant will work with telecommunications purveyors to ensure that future residents will have access to telecommunications services. f. Safety and Noise Element
GOAL S-1: Emergency Response. Effective emergency preparedness and rapid response to natural or human induced disasters are provided that minimize the loss of life, damage to property, and disruptions in the delivery of vital public and private services during and following disaster.

A lake area will be reconﬁgured as visual feature within the new development and will serve as a multi-function water body. The lake serves as a water retention basin, as a ﬂood control facility in times of heavy rain, and also as an emergency water supply in the event of ﬁre.

GOAL S-4: Police Services, Crime Prevention, and Protection. Quality police services are provided that protect the long-term safety and well-being of Simi Valley residents, businesses, and visitors from criminal activities.

The residential development areas of the Lost Canyons Project are designed to be accessed only through controlled access gates that may be guarded or automated. This level of access control increases the perception of exclusivity and protection from criminal activity.

Furthermore, the Lost Canyon Project will include development standards that support defensible space concepts (site and building lighting, visual observation of open spaces, secured areas, etc.) in the design of new development and rehabilitation projects.

[55]
62 Ord. No. 1374
GOAL S-5: Geologic and Seismic Hazards. Adverse effects to residents, public and private property, and essential services caused by seismic and geologic hazards are minimized.

The Lost Canyons Project incorporates several measures to reduce slope and ground stability hazards. These include reducing hillside grading and development by concentrating development primarily in the previously altered areas of the site, thus preserving steep hillsides and prominent ridgelines; and avoiding more severe terrain, which is more subject to ﬂood, erosion, landslides, and mudslides.

Identiﬁed landslides in proximity to development and road improvements may be remediated based on recommendation by geotechnical engineer.

Areas of potential geologic or soils instability will be appropriately investigated and mitigated during all phases of the planning, design, and development of Dry and Tapo Canyons. It is expected that the mitigation of geotechnical issues will be completed as part of the development process, with ﬁnal reconciliation required prior to issuance of building permits.

GOAL S-7: Fire Protection. People and property in Simi Valley are protected from urban and wildﬁres.

Brush ﬁre hazards will be minimized by the provision of fuel modiﬁcation zones between development and natural open areas. This includes the utilization of ﬁre retardant materials and establishing minimum distances between structures and natural open areas or “wet zones” (irrigated vegetation). The irrigation lake, located in the central area of the Project Site, can serve as emergency water storage and will continue to provide regional ﬁre protection. Additionally, all development will adhere to the Ventura County Fire Department and California Fire Protection Plan and Fuel Modiﬁcation zones.

GOAL S-8: Flood Hazard Protection. Residents, workers, and visitors are protected from ﬂood hazards.

The Lost Canyons Project incorporates City, County, and State design criteria and requirements related to ﬂood control and is described in this Chapter.

GOAL S-11: Local Infrastructure, Facilities, and Structures. The built environment is adapted to a warmer and drier climate with increased ﬁre risk, particularly in the wildland-urban interface, including public infrastructure, facilities, and structures and private development, to effectively prepare for anticipated climate risks.

The Project contains directives for builders to comply with City, County, and State design criteria and requirements for structural hardening, home weatherization, and other design measures to help minimize climate risks. Additionally, all development will adhere to the Ventura County Fire Department and California Fire Protection Plan and Fuel Modiﬁcation zones.

E. Land Use Zoning
In accordance with State and municipal law, the Speciﬁc Plan functions as the zoning ordinance for the Project Area. The provisions of this Speciﬁc Plan Amendment are consistent with the Development Code, Title 9 of the Simi Valley Municipal Code. To the extent this Speciﬁc Plan speciﬁcally addresses a zoning standard, the Speciﬁc Plan controls.

1. Hillside Performance Standards
The City recognizes the hills within and adjacent to the City as signiﬁcant features of the community. Title 9, Chapter 32 of the Municipal Code sets forth Hillside Performance Standards (HPS) to guide development within hillside areas. Visually prominent ridgelines are deﬁned within these standards. Development of the Lost Canyons Project will comply with the City’s Hillside Performance Standards (HPS) requirements (Simi Valley Municipal Code Title 9, Chapter 32). The previous golf course is the optimal location for residential development consistent with the HPS.

2. Land Uses Allowed Within Residential Zoning Districts The residential development pattern is designed to complement the natural features of the land, and minimize impacts to natural vistas and slopes, while also providing for a landscape buffer/fuel modiﬁcation zone between the built environment and the natural open space areas.

As shown in Exhibit #9, General Plan Land Use Designations, Residential land uses consist of three (3) distinct categories.

August 2026 - III. Dry and Tapo Canyons
[57]
64 Ord. No. 1374
The Lost Canyons Project Site is comprised of the following residential categories:

Residential Estate, Residential Low, and Residential Medium Density. These districts govern the development standards for residential development within the Project Site.

All applicable development and design standards of the Simi Valley Municipal Code, Title 9, Article 1, et. seq. of the Simi Valley Development Code apply within the Lost Canyons Project Site, unless otherwise speciﬁed below.
a. Residential Medium Density / RM(SP) (0-3.7 dwelling units/ acre)
This zone contains single-family detached dwellings on lots (minimum of 6,000 square feet) as shown on Conceptual Land Use Plan (Exhibit #6) and identiﬁed in Table III-2, Planning Area Statistical Table. The purpose of this zone is to allow a medium density residential uses, such as Product A: 60’ x 100’ lots, Product B: 65’ x 100’ Lots, and Product C: 60’ x 120’ Lots within Planning Areas 1, 2, 4, 5 and 6. This zone creates integrated housing to encourage pedestrian and non- vehicular mobility, making the community spaces conducive for social interaction.

This unique residential product type will enable the City of Simi Valley to offer a community of housing and lifestyle not currently available. b. Residential Low / RL(SP) (0-2.6 dwelling units/acre) This zone contains Planning Areas 3 and 10 and consists of single-family detached homes on 90x110’ lots (Product D) with not less than eighty percent (80%) of the lots being a minimum of 1/3-acre (14,520 square feet) in size in size as shown on Conceptual Land Use Plan (Exhibit #6) and identiﬁed in Table III-2, Planning Area Statistical Table. The purpose of this zone is to provide for detached housing on a variety of lot sizes that buffer the project core (residential medium housing) and the natural hillside. These homes are situated such that they have views of the natural surrounding landscape.
c. Residential Estate / RE(H)(SP) (0-0.5 dwelling unit/acre) This zone is permitted in Planning Area 8 and allows for single-family detached homes on estate lots, a minimum of 20 acres in size, with minimum building pads of 6,000 square feet as shown on Table III-2, Planning Area Statistical Table.

The purpose of this zone is to provide for detached estate style housing with the opportunity for rural character of permitted uses and horse keeping. The Estate Lots also serve as a buffer to the natural areas of the site from higher density housing types. These lots are situated along the northern and southern boundaries of the Lost Canyons Project Site and are classiﬁed “RE (SP),” with an (H) Horse Overlay District.

3. Land Uses Allowed Within Open Space Zoning District
This zone contains Planning Area 9 to maintain the natural character of the canyons and hillsides. Preserved open space is the primary element of the Project Site, comprising most of the southerly portions of the property.

Exhibit #10, Conceptual Open Space Plan, illustrates the Open Space network within the Project Site.

A signiﬁcant portion of the Lost Canyons Project Site will be preserved as open space, and identiﬁed on the Land Use Plan as Open Space. These areas may be subject to a Conservation Mechanism (as shown in Exhibit #7 Conservation Map) designed to preserve open space, as outlined in Section B.1.a.i within III. Tapo and Dry Canyons starting on Page 38. These Open Space areas encompass the open areas and vistas within the Lost Canyons Project Site. These portions of the Project Site will remain in their natural state, free from intensive development activities. The intent is to allow for active trails so that residents and the public can enjoy the natural surroundings.

4. Lost Canyons Planning Areas (PA)
Planning Areas inform the Phasing Plan and encourage development in an organized and holistic approach. There are ten total planning areas which make up the total Lost Canyon Speciﬁc Plan Boundary. The Planning Areas are grouped primarily by use, categorizing similar uses into the same Planning Areas. Planning Areas 1 through 7 make up majority of the development within the plan. Additional development occurs to the south in Planning Area 10. Planning Area 10 also contains an existing residential dwelling unit, which is grandfathered into the Speciﬁc Plan, but does not propose new residential development. Planning Area 10 may also include public improvements. The following descriptions are of the numbered Planning Areas within the Project Site boundaries.

a. Planning Area 1 –Residential Medium/Zoning RM(SP)
Planning Area 1 will feature detached homes referred to as Product A: 60 x 100’ Lots. The lots are oriented to provide a connected and walkable neighborhood experience and the homes will create a small neighborhood that invokes a “village” feel. All homes are accessed via private roadways with gated access points.

Planning Area 1 will utilize fundamental design principles to create access, variety, organization, and identity. In general, building setbacks are typically kept to a minimum to create a more deﬁned space, and building massing and height encourages prominent architectural accent buildings. Residential homes will be oriented to maximize views of natural features. Pedestrian links will connect Planning Area 1 with the other Project Planning Areas. All of these efforts will help to create a strong sense of identity and interest within the greater neighborhood pad itself. All homes are accessed via a private roadway with gated access via Lost Canyon Drive.

73 Ord. No. 1374
h. Planning Area 8 – Estate Lots – Residential/Zoning RE(H)(SP) Residential Estate Lots are currently being proposed within the greater Whiteface Speciﬁc Plan, and are permitted in Planning Area 8. These lots have a minimum lot size of 20 acres. Lots of this type are situated at the northern and southern edge, and permitted through the southern portion of Tapo and Dry Canyon. These minimum twenty (20) acre lots allow a transition, from the residential medium and low to the north and south into the Open Space designated area.

The northern Estate Lots enhance the protection of the existing Whiteface escarpment landform and adjacent ridgelines to the northeast that serve as a backdrop to not only the Project Core and the custom residential lots, but the entire City of Simi Valley. The southern Estate Lots may also serve as a buffer to the existing residential development to the south of the Lost Canyons Project Site.

To accomplish this aesthetic transition, the concept for the hillsides outside the buildable pad within the natural, open space areas are to be preserved to protect the existing natural surrounding vegetation on the slopes and ridgeline areas within each of the Estate Lots. Private preservation will provide a greater degree of control over those portions subject to conservation by restricting access rather than open, allowing for more diligent monitoring of the preserved land. i. Planning Area 9 – Open Space
Open Space encompasses the open areas and vistas within the Lost Canyons Project Site. Active multi-purpose trails will meander throughout the site so that residents and the public can enjoy the natural surroundings (see Exhibit #10, Conceptual Open Space Plan).
j. Planning Area 10 – Ditch/Anderson Lots, Existing Development and No Planned Development Areas
Planning Area 10 is located in four areas of the plan, including two areas along the southern edge of the project boundary, one area along the northern boundary of the Speciﬁc Plan near Bennett Road and one along the southeastern edge of the boundary, along Tapo Canyon Road.

PA 10 to the south on Ditch and Anderson includes two Residential Low lots that will tier off of the existing residential development that is situated south of the Speciﬁc Plan Boundary. One lot extends from Anderson Road and the other from Ditch Road. These lots are each planned to include one 90x110’ lot (Product D).

PA10 to the north includes one existing residential unit, which has been grandfathered into the plan as an existing-nonconforming use.

PA10 along Tapo Canyon Road has no existing development and no proposed development other than street improvements and RSPRD trails.

k. Oil Wells
There are currently 51 closed oil wells located within the Project boundary located within Tapo Canyon south, and South of Lost Canyons Drive (see Exhibit #13, Non-Active Drill Site Easement Locations). There are no residential units planned in areas where oil wells are located. This area has been historically referred to as the “Old Simi Oil Field.” Numerous oil companies have previously operated within this area, the most recent being Seneca Resources, a Division of National Fuel Gas Company, Texaco Exploration and Production, Inc. and Midland Oil Company.

5. Development Standards
a. Approach to Lost Canyons Development Standards
The overall concept for the Lost Canyons Project Site, depicted in Exhibit #6, Conceptual Land Use Plan, is based upon a comprehensive analysis and understanding of the property’s natural systems. These systems include topography, plant and animal communities, hydrology, climate, soils, and geology.

Included within the Project will be a maximum of up to 364 new homes and an associated recreation center. Table III-3, Setback and Building Height Standards, provides the site development standards that apply to the entire Lost Canyons Speciﬁc Plan area. Included within Exhibit #12, Proposed Planning Areas, are the Planning Areas which comprise the Lost Canyons Project Site.

The purpose of the development standards and the Lost Canyons Design Guidelines (attached hereto as Appendix A) is to ensure that all future site development maintain the same high standard of aesthetic quality, appearance and sustainability intended throughout the development lifetime of Lost Canyons.

The development standards below, in conjunction with the Lost Canyons Design Guidelines (Appendix A) establish the Project’s overall aesthetic standard and development requirements for development within the Speciﬁc Plan area.

Adherence to the development standards and the Lost Canyons Design Guidelines will ensure quality of design and aesthetic character throughout the Speciﬁc Plan area during Project implementation, regardless of the individual project, the applicant, or the time frame.

The Speciﬁc Plan’s development standards and the Lost Canyons Design Guidelines (Appendix A) are a comprehensive set of rules and regulations that will guarantee architectural and aesthetic integrity in the Speciﬁc Plan area, while providing a range of options to ensure that the Project is implemented in a unique and appealing fashion. Accordingly, to the extent this Speciﬁc Plan provides a development standard or design guideline criteria that differs with any portion of the Simi Valley Municipal Code, the Speciﬁc Plan’s development standard or design guideline criteria shall apply to the Lost Canyon’s development.

Subdivisions, land uses and structures, and alterations to existing land uses and structures, shall be designed, constructed, and/or established in compliance with Table III-3, Setback and Building Height Standards, and the development standards listed below

78 Ord. No. 1374
F. Visual
Lost Canyons views will be predominantly internal to Dry and Tapo Canyons, with views from Simi Valley to the proposed development area screened by the natural terrain. This will be maintained by locating development in lower elevations where the Lost Canyons homes will remain, in a large part, screened by interspersed ridgelines, existing foothills, and landscaping. The proposed site plan also minimizes visual impacts through contour grading and complying with the Hillside Performance Standards by respecting natural topography to the extent possible. The proposed project will also serve to preserve the views of Whiteface as seen from the valley ﬂoor.

G.Infrastructure

1. Vehicular Circulation
a. Circulation and Access
The Lost Canyons Project Site is accessible by two (2) minor arterial roadways; Erringer Road and Tapo Canyon Road (see Exhibit #14, Local Area Off-Site Circulation).

Erringer Road and Tapo Canyon Road intersect State Route 118 approximately 1½ miles south of the Project Area. Erringer Road, portions of Lost Canyons Drive, and Tapo Canyon Roads are identiﬁed as Scenic Roadways within the City’s General Plan. These minor arterial roads will be designed with left and right turn lanes and bus turnouts at all intersections, as required by the Director of Public Works, along with traffic signals at major intersections.

Streets may incorporate passive traffic calming devices such as landscape islands (on entry streets), slight variations in road curves, parking pullouts, and where appropriate and feasible include the use of roundabouts approved by the Director of Public Works. The incorporation of roundabouts shall be feasible within site planning and engineering constraints.

The primary entry towards the Lost Canyons project site is from Lost Canyons Drive at its intersection with Tapo Canyon Road. Both roadways are currently two- lane roadways.

b. Internal Circulation (Private Streets, Driveways)
In order to minimize grading related impacts to hillsides and natural terrain, all direct access to the homes and amenities within the Project Area will be from private internal roadways accessed via Lost Canyons Drive (see Exhibit #19, Conceptual Circulation Plan). This Speciﬁc Plan provides for alternative roadway designs from those found in the City that are typical to development in non- hillside areas. For example, portions of roadways may exceed, for short segments, typically acceptable grades in order to minimize vertical cuts through some of the hillsides. Limiting parking to designated pullouts (bays) reduces the pavement width resulting in reduction in earth moving activities and site disturbance; in addition to providing a character and scale that is difficult to achieve with street widths set forth in the current City standards, which provide unlimited parking along roadways.

The private roadways will be built as low speed, pedestrian-friendly streets through the project. These roadways have been narrowed for traffic calming purposes. A reduced pavement width also allows opportunities for environmentally sensitive landscaping along the roads and intersections.

Parking, circulation patterns, and streets shall be designed to complement the natural contours of the land and retain natural features of the hillsides and reduce street lengths.

To minimize grading and provide a rural setting, private street widths may be reduced, and sidewalks along these streets may be eliminated. On-street parking has been limited to narrow the paved road section thus providing more opportunities for enhanced landscaping. Road segments with steeper grades have been utilized in some areas to minimize grading impacts by responding to the existing terrain.

The design of the private streets is intended to encourage lower traffic speeds to promote safety for both people and cars. The parking and street design standards shall provide safe vehicular access while promoting the vitality and charm of a rustic residential neighborhood.

Several classiﬁcations of roadways, with their representative cross sections shown in Exhibits #18-21, and within Table III-4, Lost Canyons Roadway Sections, provide service to the Lost Canyons community. The following provides a discussion of the on-site roadways designated within the Project Site.

[84]
91 Ord. No. 1374
The nearest bus stop is located approximately one (1) mile south of the Project Site, near the intersection of Tapo Canyon Road and Township Avenue (per Simi Valley Transit routes effective October 2005). Lost Canyons Drive will be improved as part of the Project to meet City standards and is thus adequate to handle any future extension of transit service up to and/or into the Project Site. Bus turnouts would be required at any new bus stop location. Simi Valley Transit also offers a Dial-A-Ride curb-to-curb service for disabled and senior persons.

The nearby Simi Valley Metrolink Station is located southeast of the Project Site at Los Angeles Avenue and Stearns Street.

2. Pedestrian Circulation
a. Speciﬁc Plan Regional Trails
Trails provided within the speciﬁc plan provide access to the Rancho Simi Recreation and Park District’s east-west trail linkages, as well as trail access to the Whiteface escarpment. An RSVRPD public trail head and parking area will be located on the east side of Tapo Canyon Road, as shown on approved TTM 6127.

It will serve as the staging area for a trail that crosses the foothills between South Tapo Canyon and Dry Canyon. The future trail continues across Dry Canyon to the south and accesses trail easements on the neighboring Big Sky development.

Signage may be provided along the trail and at intersection points for direction and wildlife information. This trail system provides trail linkages for the public.

The surfaces for the improved multi-purpose trails located within the developed portion of the Project Site will be compacted dirt or decomposed granite with the implementation of standard erosion control measures on steeper gradients, in conformance with the standards of the Rancho Simi Recreation and Park District (see Exhibit #8, Conceptual Trails Plan).
b. Speciﬁc Plan Community Trails
The community trails will be provided as shown in Exhibit #8 as well as a public trail head to be accessed off of Bennett Road.

Various community trails will be provided within the plan area for pedestrians.

One trail is accessed from the future trail head at the Lost Canyons Drive and Tapo Canyon Road intersection and runs along the northern edge of Lost Canyons Drive. Additional trails will be provided north of the residential uses, and all trails can be accessed by the public from the proposed trail head at Bennett Road. The trails will have two connection points from the residential areas, one along the northern edge in Planning Area 5 and one along the eastern edge in Planning Area 3. The trails will serve pedestrians only and offer various routes for walking, running and hiking. See Exhibit #8, Conceptual Trails Plan.

3. Domestic Water
The Lost Canyons Speciﬁc Plan Area is located within the service boundaries of the Ventura County Waterworks District No. 8 (the “District”). Water supply originates from the Calleguas Municipal Water District and is conveyed to the project site through the 1248 and 1357 pressure zones via several transmission lines of varying size. For water pipe sizing, locations, and improvements, see Lost Canyons Residential Development Water System Master Plan prepared by RTM Engineering Consultants, January 15, 2026.

The criteria used to determine the water system facilities required is based on the current standards of the District. Delivery of the water service to the Project will require the construction of new improvements as well as upgrading of existing facilities. New facilities to be constructed include the completion of a looped pipeline system which connects existing transmission facilities located at the intersection of Tapo Canyon Road and Lost Canyons Drive to a new approximately 580,000-gallon reservoir located at elevation 1537 on the Project Site; and to the existing 16-inch Big Sky transmission pipeline located within Lost Canyons Drive. Additionally, the Project will construct a new pumping station to provide supply to the 1537 reservoir and pressure zone. The pumping station will connect to the existing 1357 Tapo Street Pump station until such time as the city completes the proposed Walnut Creek pumping station which will provide regional pumping needs. With these system improvements, the Project will be assured a reliable water supply with water service pressures to address lot-speciﬁc pressure needs.

4. Sewer
The entire Lost Canyons Project Area falls within the jurisdiction of the City of Simi Valley and its Sanitation Services Division (SVSSD). The proposed Project wastewater system would connect to the existing sewer lines at Tapo Canyon Road and Lost Canyons Drive. There is adequate capacity in the wastewater treatment and effluent conveyance systems to accommodate ﬂows from the Project, with some system improvements which have been modeled and discussed with the SVSSD. These improvements would be performed in conjunction with development of the Project to ensure adequate capacity is maintained to address the development. See Exhibit #22, Conceptual Sewer Plan.

The subsequent Tentative Tract Map (TTM), Planned Development Permit, and other related approvals will address the Project-speciﬁc measures to be incorporated.

5. Storm Drain/Flood Control
The Lost Canyons Speciﬁc Plan area is located within the boundaries of Ventura County Watershed Protection District (VCWPD). The City of Simi Valley deemed the Lost Canyons Project (Project) Tract Tentative Map 6127, Speciﬁc Plan Amendment and its associated application phases complete prior to Ventura County’s adoption of the 2011 Technical Guidance Manual for Stormwater Quality Control Measures (2011 Technical Guidance Manual).

Pursuant to the terms of the 2011 Technical Guidance Manual (see e.g., page 1-8), the Project will comply with the performance criteria set forth in the 2004 Technical Guidance Manual for Stormwater Quality Control Measures under Board Order 00-108.

The Project is planned and designed to maintain the natural characteristics of the channel to the extent possible consistent with the 2004 Technical Guidance Manual. The Project’s August 2026 - III. Dry and Tapo Canyons Whiteface Speciﬁc Plan Volume II - Lost Canyon
[86]
93 Ord. No. 1374
storm drainage system has been designed with two objectives: 1) meet storm drainage design requirements of the City of Simi Valley and VCWPD, and 2) minimize impacts to the existing channels and support the natural vegetation and wildlife.

Two independent watersheds, Tapo Canyon and Dry Canyon, extend through the Project site. The Tapo Canyon watershed is generally located on the east side of the Project and initiates beyond the Project’s northern boundary. This watershed includes approximately 13,182 acres at the conﬂuence with Arroyo Simi and ultimately drains to Arroyo Simi.

The Dry Canyon watershed is generally located on the western edge of the Project and includes approximately 2,234 acres at the conﬂuence with Arroyo Simi. The Dry Canyon watershed initiates above the north boundary of the Project and ultimately ﬂows to Arroyo Simi. The Project will not substantially obstruct or alter the major drainage course of each of these watersheds.

The subsequent Tentative Tract Map (TTM), Planned Development Permit Modiﬁcation, and other related approvals will address the Project-speciﬁc measures to be incorporated.

In general, storm water management plans will be developed to meet NPDES requirements. Best management practices will be developed based upon the Ventura Countywide Stormwater Management Program (VCSMP) and the City of Simi Valley Water Quality Permit to reduce and control the impacts of stormwater runoff pollution and erosion upon the receiving waters. Stormwater treatment systems, including detention basins and structural stormwater treatment systems will be designed and constructed for water quality treatment. A number of debris basins are proposed throughout the Project to collect debris produced upstream of the developed area and to meet the Project’s requirements for debris mitigation. These measures are being evaluated based on the limits of the Project’s disturbance and are not intended to address regional debris mitigation.

Extended detention facilities are proposed to meet ﬂood control requirements for the Project’s developed areas. These facilities will consist of a primarily off channel drainage facilities intended to mitigate the incremental runoff contributed by the proposed development and meet the speciﬁc impacts of the developed areas.

The City of Simi Valley’s Master Plan of Drainage previously depicted two regional drainage basins one of each located on Tapo Creek and Dry Canyon. Tentative Tract Map 6127, Final Map 6127-1 and the associated Speciﬁc Plan Amendment memorialized the elimination of the Dry Creek regional basin. Additionally, an easement was offered to the City of Simi Valley for the future design and construction of an enlarged regional basin on Tapo Creek. This offer was made over Lot BJ of Final Map 6127-1.

H.MAINTENANCE RESPONSIBILITIES
This section describes the various agencies or groups that will be responsible for maintaining the different land uses within the Project Site.

1. City of Simi Valley
Upon ﬁnal acceptance, the City will maintain the streets and on-street bikeways for Tapo Canyon Road and Lost Canyons Drive.

2. Open Space Conservation Entity(ies)
A signiﬁcant portion of the Project Site will be maintained as open space, and will be implemented through a Conservation Mechanism as shown in Exhibit #7, Conservation Map. Responsibility for maintenance of the property will be determined by the legal mechanism preserving those portions of the property which will be maintained as open space.

In order to accomplish the aesthetic vision for the Lost Canyons community, the concept for the hillsides between the buildable pads and the natural open space areas are planned to have an appropriate Conservation Mechanism, in order to preserve and complement the existing natural surrounding vegetation on the slopes and ridgelines. Private preservation of the Whiteface easement is preferred because it will provide a greater degree of control over those portions subject to conservation. Access can be restricted rather than open, allowing for more diligent monitoring of the preserved land and will be determined by the appropriate legal mechanism.

3. Rancho Simi Recreation and Park District
The Public Multi-Purpose Trails located throughout the Project Area may be maintained by the RSRPD. The Rancho Simi Recreation and Park District (RSRPD), and/or other public or non-proﬁt agencies may also maintain the dedicated open spaces.

4. Ventura County Watershed Protection District
The area for ongoing regional ﬂood control purposes will be maintained by the VCWPD.

5. Master Homeowners Association
All common areas, as identiﬁed on the subsequent Tentative Tract Map(s), Planned Development Permit(s), and other related approvals shall be maintained by a Homeowners Association (HOA). The HOA will be formed to provide for the maintenance of: slope areas not located within individual lots; fuel modiﬁcation zones; all landscaping and irrigation in the public rights-of-way and private streets, including parkways, pedestrian pathways, and medians; landscaping and irrigation adjacent to water tanks; storm drain facilities that may include surface drains, storm drains, detention basins, debris basins, stormwater pollution control devices and other appurtenances thereto; and other landscaping, irrigation, and improvements in common areas. Landscape maintenance may include, but not necessarily be limited to, weeding, removal, and replacement of dead or dying plants, pruning, irrigation management, and periodic fertilization. The Applicant shall submit, concurrent with Planned Development Permit and related approvals, a master maintenance plan showing all areas within the Project Site, for which the HOA is to have maintenance responsibility.

The ﬁnal master maintenance program and plan is to be reviewed and approved by the Public Works and Environmental Services Departments prior to the approval and the recordation of any Final Map.

The HOA will be responsible for certain, designated maintenance responsibilities related to the public open space properties to be dedicated to a public entity(ies). These include:
(1) maintenance of those portions of required fuel modiﬁcation buffer zones located within the public open space parcels, (2) maintenance of all drainage devices located within the public open space parcels not maintained by public agencies, (3) HOA private streets and driveways, (4) The Recreation Center, and (5) any other maintenance required by the City of Simi Valley, Ventura County Watershed Protection District, Department of Fish and Game, or other agencies with jurisdiction over site resources. A Maintenance Agreement between the HOA and the governmental entity(ies) will deﬁne any required maintenance responsibilities and will be recorded as part of the Project’s Conditions, Covenants, and Restrictions (CC&Rs).

The Master Developer shall establish the Lost Canyons HOA for maintenance of all common areas included within the Project Site. The HOA shall include broad representation from the community and shall enforce the recorded CC&Rs as prepared by the Master Developer. The CC&Rs will implement the development standards, private uses, and maintenance program for each Planning Area within the Project Site.

I. PHASING
The infrastructure necessary for each individual Planning Area of the Project Site shall be installed in phases by the Applicant and/or the Builders. Refer to Exhibit #25, Proposed Phasing Plan. All of the improvements on Tapo Canyon Road and Lost Canyons Drive will be completed consistent with the project phasing, unless an alternate time limit to complete each street is approved with the Tentative Tract Map and Planned Development Permit. Below is an outline of the amenities and total units to be built in each phase.

Phase 1. Phase 1 of the project build out includes the development of approximately 184 units and three community parks (the Main Entrance Park, the Overlook Park and the Creek Park) as well as the improvements to Lost Canyons Drive.

J. CONSERVATION/PRESERVATION

1. Oak Tree Preservation
Chapter 9-38 of the Simi Valley Development Code requires that all mature trees within a development area be identiﬁed, and a plan prepared for the preservation, replacement, or relocation of Mature Trees. A Horticultural Tree Report has been prepared for the Lost Canyons Project Site, which inventories the mature trees and identiﬁes the best candidates for relocation based on several factors including health, size, slope, and adjacent boulders or vegetation within the development area and the open space areas.

2. Energy Conservation
The Project Site is located within the inland foothills of southeastern Ventura County.

Summer temperatures often reach 90 degrees or higher and overnight winter temperatures can reach freezing. The need for energy conservation is important in an area with such a diverse seasonal climate. The Project Site will comply with Title 24 requirements. Residential and other development within the Project Site will incorporate energy saving features and resource conserving ﬁxtures. All new development will incorporate insulated water heaters, efficient insulation in walls and ceilings, dual range thermostats, newer more energy-efficient water and space heaters, and low electrical- usage appliances. Furthermore, trees have been included adjacent to paved areas to provide shade and help mitigate the effects of solar heat absorption. Deciduous trees should be planted adjacent to homes to provide shade from summer sun and allow inﬁltration of winter sun.

3. Water Conservation
A number of water-conserving measures are incorporated into the Project, including the use of drought-tolerant plant species and efficient irrigation systems.

The water purveyors serving the Project do not provide or anticipate providing facilities for reclaimed water use in landscaped areas. Landscaping will be irrigated with potable water. The revegetation of landscape areas adjacent to open space utilizes a drought- tolerant plant palette. This landscape design feature supports water conservation measures through the reduced need for supplemental irrigation water and utilization of non-potable water service.

4. Green Building Techniques
Green Building Techniques will be incorporated as part of future residential development within the Lost Canyons Project with the intent of using effective building techniques that minimize impacts to the environment, energy resources, and raw materials. These Green Building Techniques are contained within Appendix A, Lost Canyons Design Guidelines of the Speciﬁc Plan. The Lost Canyons Design Guidelines and Green Building Techniques provides a combination of objectives, and ways of implementation for developers and builders to pursue and achieve a direction in reducing greenhouse gas emissions in response to AB 32 and to become energy and resource efficient. The end result of the implementation of these guidelines is to reduce the overall carbon footprint impacts on the Project and assists in supporting “cooler communities” and effectively using energy and material resources.

August 2026 - III. Dry and Tapo Canyons Whiteface Speciﬁc Plan Volume II - Lost Canyon
[92]
99 Ord. No. 1374
The Green Building Techniques within the Design Guidelines will serve the following functions:
(a) Assist in addressing AB 32 Green House Gas emission reductions; (b) Community recycling and reclaiming resources such as water, soils, and wastes that can reduce impacts to water quality;
(c) Establish guidelines and opportunities for “practical green” solutions for residential development for effective ways in reducing energy and water consumption;
(d) Assist project designers in preparing building design for resource efficiencies; and
(e) Support new technologies that improve residential living standards more effectively.

On a City-wide level, future recycled water systems, building technologies, as well as waste disposal and recycling programs should also be employed as they become available. New technologies for generating energy and power should be embraced as it could potentially reduce operational, maintenance, and living costs.

K. IMPLEMENTATION
This section provides a more detailed discussion of the implementation of the Lost Canyons Project which is in addition to Chapter IV of this Speciﬁc Plan. Implementation is carried out through the application and processing of standard City approvals as set forth in Title 9, Chapter 10, and et seq. of the Simi Valley Municipal Code (Development Code).

In addition, criteria are included under which the City Council may approve Amendments to this Speciﬁc Plan. The development program for implementation of the Speciﬁc Plan and a discussion of ﬁnancing alternatives are also set forth.

The Conceptual Land Use Plan for this Project Site (Exhibit #6, Conceptual Land Use Plan) is designed to integrate a variety of open space, park, multi-purpose trail, trailhead, residential, ancillary commercial, and related uses within the community while providing a compatible proﬁle for development in the canyon ﬂoors, and protecting the hillsides and vistas for the general public. Preservation of natural watercourses, speciﬁed mature trees, and views are purposefully incorporated into this Land Use Plan concept. The Speciﬁc Plan land use categories for the Project Site include residential, commercial recreation, and open space. A land use acreage summary providing the acres and percent of total area for the various land use categories and zoning districts within the Project Site is included in Table III-1, Land Use Acreage Summary and detailed in Table III-2, Planning Area Statistical Summary.

1. Implementation Procedures
Implementation of the Whiteface Speciﬁc Plan Amendment No. 6 is carried out by the preparation, ﬁling, and processing of applications for land use permits, Tentative Tract Maps, Tentative Parcel Maps, and other approvals pursuant to the City’s Municipal Code.

The Tentative Tract Map and Planned Development Permit for the Lost Canyons Project will be subject to City Council approval with recommendations made by the Planning Commission. Should future economic or development conditions make it desirable to amend this Speciﬁc Plan, the procedures described in the Municipal Code shall govern such amendments.
a. Speciﬁc Plan Amendment Adoption
This Whiteface Speciﬁc Plan Amendment No. 8 has been prepared, submitted, and approved in a manner consistent with California Government Code Section 65451, as well as all pertinent sections of the Municipal Code. Adoption of this Speciﬁc Plan Amendment has been by Ordinance of the City Council. b. Implementation
All applicable standards and Codes of the State of California, and Federal Government shall apply to this Development. In addition, all standards and Codes of the City, with the exception of those standards contained herein shall apply to this Development. In cases where speciﬁc standards are not addressed by this Speciﬁc Plan Amendment, the standards contained within the appropriate sections of the Simi Valley Municipal Code and Development Code shall be followed.

When design guidelines are not addressed in the Lost Canyons Design Guidelines of Appendix A, herein, the guidelines within the City’s Residential and Landscape Guidelines shall apply.

The Project Site is zoned as follows:

Table III-7 Lost Canyons Zoning
Speciﬁc Plan Land Use SVMC Zoning
Residential Estate Residential Estate Density (RE/H/SP) Zone Residential Low Residential Low Density (RL/SP) Zone
Residential Medium Residential Medium Density (RM/SP) Zone Open Space Open Space (OS/SP) Zone

[94]
101
Ord. No. 1374
The foregoing base zones are followed by the suffix (SP) to signify that, in each case, the zoning district is controlled by this Speciﬁc Plan Amendment and the Simi Valley Municipal Code.

The grading, street and infrastructure improvements, including underground utility lines, streetlights, medians, parkway landscaping, and the backbone infrastructure shall be constructed concurrently with each phase of constructing residential development, and offered for dedication to the City (in the case of public street rights-of-way), or any public easements dedicated to the various utility providers as a condition of recordation of any Final Map(s). All of the required improvements on Tapo Canyon Road and Lost Canyons Drive must be fully completed prior to issuance of the ﬁrst building permit for any habitable structure, unless an alternate time limit to complete each street is approved by the City Council upon recommendations made by the Planning Commission concurrently with the Tentative Tract Map and Planned Development Permit.
c. Minor Revisions to the Speciﬁc Plan and Related Procedures This section of the Speciﬁc Plan Amendment sets forth the regulations governing minor Lost Canyons Planning Area boundary adjustments, transfers of dwelling units from one Planning Area to another, adjustments to grading on approved tentative tract maps, and other similar minor adjustments. In the event that a change is made to the Project which does not require a Speciﬁc Plan Amendment, such a change may be approved administratively if it does not create an environmental impact not previously studied under the EIR.

The Speciﬁc Plan area has been contemplated for development for over a decade, but it has yet to be developed because of the land’s uniqueness. These unique features are not present on the valley ﬂoor. For example, the Speciﬁc Plan area is topographically challenging and has known adverse soils conditions, thus making development within the Speciﬁc Plan area difficult. Such unique topographic and adverse soils conditions have also made it difficult to design an economically feasible project. While every effort will be made to ensure accuracy in the preparation of the project’s tentative map(s) and planned development permit(s), the Speciﬁc Plan area’s topographic challenges may present unforeseeable issues that could result in the need to revise the grading design of approved tentative map(s) and related planned development permit exhibits. For example, remediation work on a landslide could result in the creation of more or even less developable land. These conditions, however, could be discovered during preliminary site preparation. Post tentative tract map approval remediation work could result in minor changes to the grading design of the approved tentative maps(s) and related planned development permit exhibit(s).

Therefore, the following is a streamlined procedure to allow certain minor changes to previous speciﬁc plan, tentative map, and planned development permit approvals that result from unforeseeable circumstances arising during post tentative tract map approval remediation work and other administrative changes.

Ord. No. 1374
Transfer of Dwelling Units: In order to promote ﬂexibility, the transfer of dwelling units from one Planning Area to another, within the Lost Canyons portion of the Speciﬁc Plan Area, will not require a Speciﬁc Plan Amendment and shall be subject to approval as part of the Tentative Tract Map, Planned Development Permit, and other related approvals. Any such transfer must be consistent with the Speciﬁc Plan’s maximum 364 single-family detached dwelling units, and shall not result in more than 364 dwelling units. The density of the receiving Planning Area shall not exceed the authorized maximum of the zone into which the residential units are being transferred.

Notwithstanding this provision, the clustering provisions of the Speciﬁc Plan shall be utilized to maintain the intent of the community character inherent in the density categories established by this Speciﬁc Plan.

Transfers of density shall be based on a plot plan, Tentative Tract Map, and other plan exhibits demonstrating that the proposed transfer would not exceed the maximum of 364 dwelling units, improve the spatial or functional relationships of the involved Speciﬁc Plan, and would materially increase the quality of land use, circulation, or conservation pattern thereof. The precise number of residential units will be updated within Table III-2, Planning Area Statistical Summary in order to demonstrate that the overall 364 number of dwelling units will not be exceeded.

Transfer of residential units from one Planning Area to another within the Speciﬁc Plan Area shall be processed as described above if:
i) The mixture of residential dwelling units will not increase either the overall density or the overall intensity contemplated by the Speciﬁc Plan. ii) The overall Lost Canyons Speciﬁc Plan total number of 364 dwelling units is not exceeded.
iii) The density of the receiving area does not exceed the authorized maximum density established within the Speciﬁc Plan.
iv) The transfer creates no new signiﬁcant environmental impacts which cannot be mitigated to a level of less than signiﬁcance.
v) The transfer of dwelling units must be located in designated residential Planning Areas, as determined by the Project’s Tentative Tract Map.

Modiﬁcations which are not consistent with all of the above criteria shall require review by the Planning Director for determination of Administrative approval or to require a Speciﬁc Plan Amendment.

Ord. No. 1374
Changes to Grading: The Project developer may submit a request accompanied with plan exhibits, supporting documents/studies, applicable review fee, and other related information for consideration of proposed changes to the approved grading elevations, for review and approval by the City Engineer and Director of Environmental Services provided no new signiﬁcant environmental impacts are created or identiﬁed, and no previously insigniﬁcant impacts are increased to a level of signiﬁcance. The allowed changes are:

If the proposed grade of a grading plan differs from that which was approved on the tentative map by: a) no more than 2 feet of elevation increase or decrease along the Project boundary when adjacent to existing homes; b) no more than 4 feet of elevation increase or decrease along the Project boundary when not adjacent to existing homes; c) no more than 4 feet of increased elevation within the interior of the map; or d) no more than 6 feet of decreased elevation within the interior of the map, and e) the proposed changes are in conformance with the City’s Hillside Performance Standards and grading standards, then the changes in grading and corresponding adjustments to lot lines may be approved by the City Engineer and Director of Environmental Services.

Other Minor Revisions: In order to maximize the opportunities inherent in the property’s setting, it is desirable to establish parameters that allow site constraints to be addressed without sacriﬁcing the quality of the development. In particular, criteria related to minor changes to public services providers, and design guidelines for custom residential lots will not require a Speciﬁc Plan Amendment and shall be subject to review and approval by the Director in accordance with the Simi Valley Municipal Code, except as amended by this Speciﬁc Plan. These minor changes are as follows:
i) Change in utility and/or public service provider concurrently with the Tentative Tract Map/Planned Development Permit.
ii) Adjustments to open space corridors that change the boundaries of any adjacent residential development area, when the resultant total areas are within 10 percent of the mapped area, shall be considered as an Administrative Adjustment pursuant to SVMC Section 9-52.030; provided, that pursuant to SVMC Section

9.52.030.E.2 such Administrative Adjustment shall be deemed to not substantially affect the property rights of others, and shall not require a public hearing. iii) Changes to landscape materials, wall materials, wall alignment, entry and community features design, and streetscape design that are consistent with conceptual designs set forth in Appendix A, Lost Canyons Design Guidelines, shall be considered as an Administrative Adjustment pursuant to SVMC Section 9-52.030. provided, that pursuant to SVMC Section 9-52.030.E.2 such Administrative Adjustment shall be deemed to not substantially affect the property rights of others as provided in and shall not require a public hearing.

L. FINANCING
The development of public facilities and the provision of public services associated with the Project Site could occur through a combination of ﬁnancing mechanisms. These mechanisms are described below:

An infrastructure ﬁnancing program is important to implementation of the Speciﬁc Plan Amendment. The ﬁnancing program needs to assure the timely ﬁnancing of public streets, utilities, and other necessary capital improvements.

Various techniques are available for ﬁnancing of the improvements associated with Project development. The exact ﬁnancing method for various improvements will be determined in conjunction with the phasing of the infrastructure. Some of the possible funding mechanisms for improvements include, but are not limited to:

1. Impact fees;

2. Conventional subdivision ﬁnancing;

3. Turnkey construction by Project Applicants;

4. Land reservation, offers of dedication, fee dedications and/or easements;

5. Per unit hook up charges;

6. Reimbursement agreements;

7. State and/or Federal grants and loans (e.g., Federal Transportation Funds and various

8. Infrastructure ﬁnancing programs);

9. Community Facilities District (CFD); and

10. Mello Roos.

M. DEVELOPMENT AGREEMENT
The Project application may include a request for a new Development Agreement.

I. INTRODUCTION
A. PURPOSE AND INTENT
The Lost Canyons Design Guidelines establishes the desired visual character for individual neighborhoods within the Lost Canyons portion of the Whiteface Speciﬁc Plan Area, and the manner in which the developed areas should relate to the surrounding open space and adjacent neighborhoods.

The purpose of the Design Guidelines is to consistently apply community design concepts to site planning, landscape architecture, and architecture. This comprehensive approach to implementation of strategic community design elements promotes high quality standards and functions as a unifying theme to create the community character and enhance the visual quality of the homes.

The level of quality deﬁned in these standards is directed towards promoting a pleasant and attractive community environment that can complement its addition to the larger City community.

More speciﬁcally, the purpose and intent of these Design Guidelines are:
• To provide the City with the project speciﬁc level of design criteria assuring that the Speciﬁc Plan Area will develop in accordance with City’s Residential Design and Landscape Guidelines (see below);
• To provide guidance to builders, engineers, architects, landscape architects and other professionals in order to maintain the desired design quality; and • To supplement the Simi Valley Development Code on matters of residential design and provide guidance in the formulation of Covenants, Conditions and Restrictions (CC&Rs) for the land uses within the Speciﬁc Plan area. If there is a conﬂict between the Design Guidelines and Simi Valley Development Code, the Design Guidelines within the White Face Speciﬁc Plan as amended shall apply.

B. PROJECT DESCRIPTION
Lost Canyons is a unique community within the
City of Simi Valley. Comprised of approximately
1,770 acres, the Lost Canyons Speciﬁc Plan
integrates a variety of residential uses, dedicated
open space, a recreation center, natural habitat,
and trail systems all contained in a natural
canyon setting. The community concept is based
on the heritage of the land and the character
of the site. Creating the rustic appeal of a rural
neighborhood, the future community will blend
with the environment and integrate with adjacent
Whiteface neighborhoods. The development
pattern for this private, gated community sets as
its priority a balancing of the preservation of open
space with the need for an important move-up
residential housing option for the City of Simi Valley. The majority of the property will be left in a natural state, creating recreational opportunities throughout open space areas.

A network of paths and trails will be available to the existing neighborhoods adjacent to Lost Canyons. However, recreational trails are not intended for motorized vehicle use. The natural hillsides offer incredible views to the residents, reinforcing the semi-rural feel of the community.

C. APPLICATION
These guidelines form the basis and criteria
for the evaluation of plans and speciﬁcations
submitted for review and approval to the City and
the master developer. (See Whiteface Speciﬁc
Plan, Volume II - Lost Canyons, Section IV. Plan
Implementation, C. Planned)
Development/Clustered Development for
applicable development are subject to City
review and approval. It is anticipated there may
be multiple third-party builders. The builder of
each lot(s) is required to implement all provisions
of these guidelines as applicable. All development
plans, landscape plans, and graphic designs are
consistent with these guidelines. The Plan also
complies with the regulations, requirements,
standards, speciﬁcations, obligations, mitigation
measures, and guidelines of the Speciﬁc Plan.

The provisions contained in these Design Guidelines are applicable to the Lost Canyons Speciﬁc Plan Area. For design standards and regulations not contained herein, refer to the applicable provisions of the City of Simi Valley Municipal Code, Residential Design Guidelines, and Landscape Design Guidelines. The sketches and graphic representations Rustic design meshes with the rural

The Lost Canyons Sustainable Development Guidelines embody a combination of systems, objectives, and ways of implementation for the master developer(s), builders, and homeowners to investigate and pursue in order to achieve a direction in reducing greenhouse gas emissions for AB 32 and to become energy and resource-efficient. The end result of the implementation of these guidelines is to reduce the overall carbon footprint impacts on the community, City, and region.
• The Sustainable Guidelines Application Matrix will serve the following functions:

Assist in addressing AB 32 Green House Gas emission reductions; • Recycle and reclaim resources such as water, soils, and wastes that can reduce impacts to the environment;
• Establish opportunities for “practical green” solutions for the Lost Canyons Community that allow homeowners effective ways in reducing energy and water consumption; • Assist project designers in preparing ﬁnal project designs for resource efficiencies; and Support current and future technologies that improve living standards more effectively.

The guidelines are tailored to address a variety of “systems” that are focused on the residential development anticipated within the Speciﬁc Plan Area. These systems include natural resources, community and neighborhood planning, construction, implementation and life cycle operations, building interiors, and humanity. Sustainable Development Guidelines are summarized in a matrix format to provide recommended solutions to pursue in order to effectively support a “Green” and sustainable community.

The following guidelines will assist in building a “cooler community” and effectively using energy and material resources. Recycling and new technologies for generating energy and power should be embraced as they could potentially reduce operational and living costs.

The Sustainable Development Guidelines are to be supported as outlined in the following matrix.

II. SITE PLANNING GUIDELINES
A. GENERAL CONCEPTS
A team of planners, engineers, and environmental scientists studied the land and worked with City and agency staff to balance the needs of development and open space uses on this site. The following site planning guidelines are applicable for the Lost Canyons residential neighborhoods and open space uses. These guidelines should be addressed during preparation of preliminary plans and ﬁnal construction documents unless it is clearly demonstrated that certain guidelines may not be applicable, appropriate, or feasible under site-speciﬁc conditions.

B. GRADING

1. Introduction
The Lost Canyons Speciﬁc Plan Area exists
outside of the valley ﬂoor in the City. Due to this,
the Hillside Performance Standards (HPS) (Simi
Valley Municipal Code Chapter 9-32) apply to
this project. The Grading Guidelines, contained
herein, are in addition to the objectives and
policies of the General Plan, the HPS, and the
Residential Design Guidelines.
136
Ord. No. 1374
August 2026
[19]

2. Grading and Hillside Management

1. Signiﬁcant ridges, knolls, and rock outcroppings should be respected in the site design and incorporated as features where feasible.

2. Grading should emphasize and accentuate scenic vistas and natural landforms.

3. Contour grading with variable gradients should be employed where feasible to simulate the natural terrain, lessen the visual impact of large slopes, and mitigate long major uniform slopes.

4. Graded slopes should reuse topsoil and be planted and stabilized with non- toxic stabilizers in compliance with City-approved landscape, irrigation, and maintenance requirements.

5. Special attention should be given to the arrangement of landscape materials as a means of creating a natural, hillside appearance consistent with the natural areas of the site.

6. Preserve mature trees contained within the open space portions of the project and minimize grading disturbance to the edge of tree driplines and reuse existing vegetation where feasible.

7. Preserve, restore and enhance wetlands and jurisdictional waters where required.

8. Accommodate off-site ﬂows, design and construct naturalized drainage channels and maintain on-site drainage where feasible.

C. LOT DESIGN

1. Introduction
The following Lot Design Guidelines are intended to enhance ﬂexibility and encourage diversity within each neighborhood, and for the project as a functional, attractive, safe and viable community. In general, the architecture should consider compatibility with the adjacent and nearby houses that make up the block, as well as with the character of the Lost Canyons Community. In addition to harmonious building styles, architectural design should include careful consideration of form, size, color, material, rooﬂines, and accessory structures.

2. Standard Lot Design

1. Lot layout and design should integrate well with the existing built environment, as well as with the surrounding natural environment.

2. Lot conﬁgurations should allow for varied setbacks including those for reduced front yard setbacks for living areas and side-facing garages, zero lot-lines, detached garages, and other creative residential design tools.

3. Signiﬁcant grade changes should be aesthetically stepped, terraced, or retained.

4. Minimum driveway lengths for single-family homes shall be 20 feet as measured between the garage door and front property line, except in cases where reduced. 137

Design Guidelines
[20]

5. Lots at higher elevations should be sited and designed to capture view opportunities but harmonize with the natural surroundings when viewed from lower elevations.

6. Exterior radio, television, or other types of antennas and satellite reception dishes should be sited or screened to reduce visual impact.

7. House designs should emphasize changes in wall planes and vertical articulation.

8. The entry should be an identiﬁable and accessible element of the front elevation of the house, as may be consistent and appropriate with the architectural style.

9. For garages that face the street, the doors should be recessed to reduce the dominance of the garage door openings and to create greater shadow and depth effects for the garage wall.

10. The front building elevation should be designed with articulated architecture, incorporating variation in materials, changes in façade depth, and rooﬂine modulation.

11. Exterior trim and sills should reﬂect the home's architectural context and style.

12. Materials and ﬁnishes should serve to achieve and enforce a common identiﬁable theme for the house, although architecturally appropriate eclecticism is also permitted.

13. Finish treatments are to be made of materials that are durable and ﬁre-resistant.

Vents are to be composed of ember-resistant materials. Main wall colors should be compatible with the City’s semi-arid climate, where the use of muted and pastel colors provides a cooling and calming effect.

14. Trim colors that contrast with main colors are encouraged where appropriate with architectural style.

15. Roofs are to be composed of Class A Fire Rated materials that complement the building style.

16. Windows are to be dual-paned with tempered glass, and are encouraged to maximize the use of natural light.

17. Unscreened roof-mounted heating and cooling equipment is not allowed.

18. Solar panels and all solar equipment are to be concealed from public view to the maximum extent feasible without compromising the functionality of emerging technologies.

G.UTILITY AND EQUIPMENT

SCREENING

1. Introduction
Trash receptacles, utilities, and other equipment
providing service to residential dwellings are
necessary components of a new development.

However, the congregation of these items can
cause unsightly conditions that detract from the
overall aesthetic quality of the neighborhood
streetscape.

2. Utility and Equipment Screening

1. Utility connections and service locations such
as trash storage areas and air conditioning
units should be architecturally screened,
placed within an enclosed area, or otherwise
situated to avoid direct view from the street
and from adjacent houses.

2. Above-ground utility equipment should be
screened from view by the use of low walls,
hedge material, and/or vines where feasible,
subject to utility provider requirements or
restrictions.

3. Above-ground utility equipment, vents, and access doors for underground utility vaults shall be located with sufficient space to allow clearance between the screening for the utility equipment and any paved surfaces including streets, driveways, and walkways.

III. LANDSCAPE ARCHITECTURE GUIDELINES
A. GENERAL CONCEPTS
The landscape guidelines for Lost Canyons allow
for the development of residential neighborhoods
that are well-designed, functional, attractive,
safe, and respectful of the natural surroundings.

The preservation of the site’s natural beauty
is an important component of the overall
landscape design, which will be accomplished
through various means and techniques. These
include developing landscape guidelines for
the “Landscape Areas,” planting design, fuel
modiﬁcation, monumentation, lighting, and
landscape maintenance.

B. LANDSCAPE COMPONENT AREAS

1. Introduction
The landscape areas that make up the Lost
Canyons development vary from the native
landscapes of the surrounding hillsides to
the re-establishment of natural landscapes
on the project “edges” to various residential
components and manufactured slopes that make
up the project. Refer to Table III-4, Proposed Plant
Palette in Section III. J., Landscape Guidelines,
for a complete list of proposed plants associated
with each landscape area.

2. Landscape Areas

1. Community Entries
• Project Entry at Lost Canyons Drive, west of Tapo Canyon Road (refer to 3.1.a below) • Residential Entry on the north side of Lost Canyons Drive and approximately one mile west of Tapo Canyon Road (refer to 3.1.b below)

2. Residential Development and Parks
• Residential Areas (see 3.2.a below)
• Parks, Lake and Clubhouse (see 3.2.b below)

3. Landscape Areas

1. Community Entries
These features are located at the various access
points to the different development areas within
Lost Canyons. A hierarchy of entries is planned
that announce the arrival into the Lost Canyons
Project Area as a component of the broader Big
Sky community, as well as neighborhood entries
allowing access into the different geographic
environs of Lost Canyons itself. To strengthen
the concept of neighborhood integration and completion, the plant materials and design used in these areas are envisioned as similar in character. Candidate trees for relocation should be used in these features to announce arrival into this community, which is deﬁned by its relationship to the large, surrounding expanses of open space and the canyon feel.

While drought tolerant plants are preferred throughout the plan area, to create an inviting sense of place, statement trees which provide shade emphasis will be included in the entry landscaping
a. Lost Canyons Project Entry
This Project Entry, is located at Lost Canyons Drive west of Tapo Canyon Road. This location may feature entry monumentation within the median and on each side of the street and a manned building for electronic monitoring of the community facilities may be located at the northwest corner adjacent to the Lost Canyons Drive and Tapo Canyon Road intersection within Planning Area 2 subject to approval of the subsequent Tentative Tract Map and Planned Development Permit. The intent is to create a strong sense of arrival even though Lost Canyons Drive is a public street and will not be gated. Lost Canyons may contain an unmanned building within the median. Faux gates and massing of walls and landscape will foster a sense of transition from the outside world into the Lost Canyons Project Area, as well as enhancing the feeling of Lost Canyons as part of the larger Big Sky community.

Specimen trees add visual interest and provide a strong backdrop to the monumentation. The materials contemplated for the entry monuments are intended to emulate native colors and textures seen throughout the existing natural environment in the region. Intermittent re-occurrence of these materials is anticipated along roadways to add visual interest to the natural landscape and provide a design connection to the Project Entry. b. Lost Canyons East and West Entries
The Lost Canyons East and West entries are located along Lost Canyons Drive, west of Tapo Canyon Road. Electronic transponder technology, cameras and remote operation of the gates will ensure secure and expedient access to residents, guests and vendors. These gates will serve as the main entry to Planning Areas 1 through 7 (as shown in the Speciﬁc Plan, Figure #12).

Enhanced vehicular paving and/or a special curb treatment may be provided for traffic calming purposes and to create a sense of arrival. Specimen trees along the main entry and at the corners will be provided for hierarchy to the 146

community. The plant material should be consistent with the overall theme of the Project. Ornamental plant material may be used to add color to the landscape.

2. Concept Landscape Plan
a. Residential Areas
The project core is the clustering of development within Planning Areas 1 through 6. The project core includes nearly all of the development that will occur north of Lost Canyon Road. The landscape areas consist primarily of single-family residential lots (and the adjacent manufactured slopes and fuel modiﬁcation zones) located within the project core. A comprehensive landscape plan for this area will be prepared to create a strong sense of identity. Thematic plantings of trees may occur in this location, in contrast to the custom home areas, where informal massings of trees at key accent and impression points are contemplated. This area will be landscaped to blend the residential areas together with the surrounding natural landscape. b. Parks, Lake and Clubhouse
Parks, located throughout the plan area will be programmed and lanscaped following the design of the broader residential development area. Walking paths will be included in parks as well as connections to the public community trails through the Passage and Creek Parks. Trees and plants within the parks will adhere to the Ventura County Fire Department approved plants and trees. Located in Planning Area 7 is the lake and Clubhouse. This area is considered both a visual amenity and a recreation amenities. The area provides several amenities for all age groups, and may include walking paths, hard court recreation areas, children’s play area, and small-scale grass or landscaped areas. This Planning Area is intended to serve as a recreational nucleus for the Lost Canyons community, offering social, active and passive forms of recreation.

C. PLANTING DESIGN

1. Introduction
The planting design for all areas of Lost Canyons
shall be completed using sound professional
practices. The developed areas will incorporate
such techniques as screening objectionable
views, mitigating the impacts of grading on
surrounding natural areas, and “blending” or
transitioning of the proposed landscapes with
the surrounding natural areas. The proposed
plant material list contained in the Appendix, A.

Plant Palette, is designed to create an overall
project unity while still allowing the various components to have a sense of individuality.

In addition, the list is developed to allow for a blending of the built environment with the surrounding native areas. All proposed planting will be climatically appropriate and include a diverse combination of plant species appropriate for the City and the region.

2. Residential

1. Manufactured neighborhood slopes should have a transitional element of plant material linking them to the natural landscape.

2. Boulders and/or rock outcropping could be used to create a natural look linking them to the native areas.

3. A mix of drought tolerant plants should be used.

4. Thematic placement of plant material that relates to the architecture is encouraged.

5. Plant material should blend with adjacent residential areas or open space areas.

6. Non-deciduous trees should provide shading, screening and privacy where desired.

7. Perimeter areas should use more natural planting where appropriate at open space areas and/or planting scheme complimentary to adjacent neighborhoods.

8. Special interest planting should be considered, including traditional garden species and/or species recognizable from the region.

9. Incorporate native planting where possible.

10. Maximize vegetative canopy and ground cover to reduce heat gain and the need for air conditioning.

11. Water-efficient irrigation systems (drip or subsurface; “Smart Irrigation” type controllers monitor weather & soil moisture).

3. Plant Spacing and Sizing
The desired character of common area slope
landscaping is to mimic Oak Woodlands, which
once occurred on site. This landscape habitat is
characterized by groupings of trees within open
areas of low grasses and shrubs. To achieve this
effect, the sizing and distribution of slope tree
planting should be as follows:

1. One-third (1/3) of all installed trees at
15 gallon and two-thirds (2/3) of all
installed trees at 24-inch box installed
size, at an average planting spacing of 1 tree per 1,800 square feet for the area adjacent to roads.

2. The tree planting on disturbed slopes should be a mix of 15 gallon and 24” box in small groupings of 3-7 trees located amongst low shrubs and groundcovers.

4. Security Planting Design

1. Landscaping should not block the visibility of address numbers from the street.

2. Landscaping at driveways should not block the view of a seated driver from oncoming vehicles or pedestrians.

D. FUEL MODIFICATION

1. Introduction
Lost Canyons incorporates a fuel modiﬁcation zone (FMZ) that is designed to minimize the potential exposure of the development areas to wildﬁre hazards consistent with the requirements of the VCFPD.

2. Fuel Modiﬁcation Guidelines

1. The FMZ will incorporate a program of brush clearance and thinning of combustible plant materials.

2. A FMZ shall be designated around all structures as measured from face of building.

3. Scattered oak trees and thinned native plants of high habitat value may be located throughout this zone as a transition between open space and developed areas.

4. FMZs will be maintained by the Homeowner within the private lot and the Homeowner’s Association within common areas in accordance with the VCFPD guidelines (except estate lots).

Example of Fuel Modiﬁcation

Ord. No. 1374

3. Fuel Modiﬁcation Concept
Given the project location’s natural setting, wild land ﬁre hazard is a known risk to living in such an environment. The Land Use Plan currently contemplates that a Landscape/ Fuel Modiﬁcation buffer will be required surrounding each home site and structure. The exact location, dimension and requirements for the Fuel Modiﬁcation zones will be further determined and reﬁned in agreement with the Ventura County Fire Protection District and the City concurrent with the review and approval of the subsequent Tentative Tract Map and Planned Development Permit.

The following zone descriptions represent a Conceptual Fuel Modiﬁcation Plan with the treatment for the zones described:

1. Zone 0 - Ember-Resistant Zone
The horizontal area within the ﬁrst ﬁve feet around the structure will decrease the likelihood of structure ignition by minimizing the potential for direct ignition from ﬂame contact, embers accumulating at the base of walls, and indirect ignitions when embers ignite nearby vegetation, debris, or other combustible materials, which can expose the structure to radiant heat or direct ﬂame
contact. Hardscape like gravel, pavers, concrete
and other non-combustible mulch materials
are encouraged to be used in this zone.

Most vegetation in this zone is limited to ground
covers, green lawns, and a limited number of
selected ornamental plants. This zone provides
defensible space for ﬁre suppression that will be
homeowner maintained.

2. Zone 1 - Lean, Clean and Green Zone
This intermediate zone extends 30 feet from
the building structure. Zone 1 may extend to a
distance of 50 feet on slopes with a grade greater
than 20%. Decreases the probability of ﬁre
directly impacting the structure. This is achieved
by altering fuel arrangements and establishing
discontinuities between planting groups, which
restricts the pathways for ﬁre to reach the
structure and diminishes the potential for ember
generation and radiant heat exposure near the
building. This is a minimal planting zone consisting
of a limited number of ﬁre-resistant tree species,
with additional spacing will augment irrigation
and planting required, relating to manufactured
slopes and landscape requirements. The
intermediate zone provides defensible space for
ﬁre suppression and will be maintained by the
private homeowner within the private lot and by
HOA outside private lot. Special consideration
153
Ord. No. 1374
August 2026 Whiteface Speciﬁc Plan
Design Guidelines
[36]
will be given for rare and endangered species, geologic hazards, tree ordinances, or other conﬂicting restrictions as identiﬁed in the environmental documentation.

3. Zone 2 - Reduced Fuel Zone
This one hundred-foot wide zone will be the extended zone and will be designed to eliminate the spread of ﬁre in such a way as to drop and approaching ﬁre from the crown of the trees to the ground reducing the ﬂame heights, and the potential for ember generation and radiant heat exposure to structures. This may require clearance outside the 100-foot zone or setting back vegetation and trees within Zone 2 away from the 100-foot line.

Thinning will reduce existing vegetation with removal of the majority of undesirable high ﬂammable plants species including trees and tree form shrubs and will be HOA maintained.

Reduction of fuel loading is accomplished by reducing the fuel in each remaining shrub or tree without substantial decrease in the canopy cover or removal of soil holding root systems. Natural vegetation is thinned in reduced amounts as the zone moves away from development.

4. Zone 3 - Thinning Zone
This Thinning Zone will be any FMZ between 100 to 200-feet from structures and decks.

This progressive thinning zone will Mitigate the spread of ﬁre as it approaches the primary FMZ adjacent to structures. The type and density of fuels, aspect, topography, weather patterns, and ﬁre history will determine the amount of fuel reduction. It will consist of native vegetation individual thinned to reduce foliage mass or fuel loading. This zone does not necessarily require the removal of plants, but thinning those that exist. Proper thinning and spacing of remaining tree and tree form native shrubs, will reduce fuel load without overly exposing the soil to threat of erosion. Natural vegetation is thinned by reduced amounts as the zone moves away from the development, depending on fuel type in this area. Typical tree and shrub maintenance required is 3 to 5 years depending on growth and native grasses would be maintained as needed annually by the HOA. 154

E. MONUMENTS AND SIGNAGE

1. Introduction
The signage and monumentation program in the
Lost Canyons community comprises a mixture
of types, both residential and recreational. The
signage program implements a community-wide
identiﬁcation program to ensure a cohesive well-
articulated directional system for community and
City residents.

2. Monuments and Signs

1. The general approach to project
signage is one of subtlety and
understatement, limited to what is
required for safety and directional
assistance.

2. Monumentation and signage at Lost
Canyons Drive plays a signiﬁcant role
in the overall community image and
shall incorporate thematic elements
found in the proposed development’s
common architectural identity and
programming.

3. Entry monument walls, fences,
and landscaping shall comply with
the City’s Traffic Safety Sight Area
provisions and with the required sight
lines for the minimum corner sight
distances of vehicles at intersections.

4. Entry features should be constructed
with materials that are compatible
with the architecture and natural
resources found in the region.

5. Entry monument walls and signs should be separated from adjacent roadways by a landscaped area with a minimum setback of 3 feet from the adjacent hardscape surface.

6. Foreground planting in front of monument walls and signs should be selected to not obscure sign copy once matured.

F. LIGHTING

1. Introduction
Project lighting is of primary importance to the “dark skies” appeal and, as necessary, to enhance safety of all residents and visitors to Lost Canyons, both in vehicle and on foot.

In addition to safety, lighting is also a design element that adds character and enhances the project theme, adding to the overall cohesiveness of the community.

2. Lighting

1. Lighting design shall incorporate techniques to
minimize nuisance lighting from all ﬁxtures.

2. Architectural lighting ﬁxtures shall be in scale and character of the surrounding elements.

3. Exterior lighting on homes shall be fully shielded, downward facing ﬁxtures to reduce impact on “dark skies” appeal.

4. All public street lighting shall comply with City standards.

5. Lighting of monuments, signs, and key architectural features is considered important and desirable but should avoid hot spots and spill over onto adjacent open space and residential areas.

6. Architectural lighting features should be integrated into building details.

G.LANDSCAPE MAINTENANCE

1. Introduction
It is envisioned that the landscape maintenance
of Lost Canyons common areas shall continue to
improve the project aesthetics as time passes through
the formation of a master homeowner’s association
and the implementation of CC&Rs. The natural
area disturbed by development will be “blended”
to undisturbed areas over time, as the residential
neighborhoods, park, and open space grow and
mature to a complex transformation of Lost Canyons.

2. Landscape Maintenance

1. Ongoing maintenance shall be performed to acceptable industry standards. It involves, but is not limited to, adjusting watering schedules, weeding, pruning, and mowing, as climatic/seasonal concerns dictate scheduled fertilization and replacing dead/dying or diseased plants.

2. Pruning shall conform to arboricultural pruning standards to maintain health and aesthetic of plant materials; no topping of trees should be allowed.

B. ARCHITECTURAL STYLES

1. Architectural Style Selection
This section is intended to inspire architects
to employ historical precedents in creating
distinctive architecture designs for Lost Canyons.

The architecture should consider compatibility
with the adjacent and nearby houses that make
up the block, as well as with the character of
existing neighborhoods in the area.

The architectural styles suggested for Lost
Canyons include, but are not necessarily limited
to, the following:
• Mission
• Spanish Colonial Revival
• American Eclectic
• Craftsman Bungalow
• Mediterranean
• Modern Farmhouse; and
• Coastal Contemporary
These styles demonstrate simplicity and a sense
of elegance. These styles remain popular over
long periods of time and are applicable in building
the traditional community character desired for
Lost Canyons.

Other architectural styles will be considered if the
proposed style provides an appropriate richness
of design detail and can establish a common
sense of consistency with the approved styles
contained herein.

1. Mission
California was the birthplace of the Mission style, a natural extension of its early Spanish heritage. Details such as dormers or roof parapets, porch roofs supported by large arched piers, and quatrefoil windows are common in these simple, symmetrical, hipped roof homes.

California turned to the Mission style in the late 1880’s and 1890’s, with traditional design elements borrowed to adorn traditional shapes, until this style faded from favor after World War I.

Mission architectural details are summarized below:
a. Form and Mass: Balanced, symmetrical facades; simple square or rectangular shapes with hipped roofs; tile roof cantilevered from wall surface, prominent one-story porches with arched roof supports to simulate outdoor arcades providing shaded protection and a place of gathering and walking. b. Materials and Colors: Smooth wall stucco ﬁnish painted off white with tiled roofs.
c. Openings and Details: Scalloped front facades and walls pierced for the hanging of bells and ornamental openings heighten the sense of entry and arrival; Quatrefoil windows are common; large glass areas are oriented to outdoor arcades (corridors) and quadrangles.

2. Spanish Colonial Revival
Spanish Colonial Revival architecture is a mixture of styles derived from many sources, including southwest adobe architecture, late Moorish architecture, medieval Spanish church architecture, provincial Italian architecture, baroque architecture of colonial Spain and Portugal and the Pueblo and Mission styles.

The style began to gain acceptance with the popularity of the Spanish Colonial buildings designed for the 1915 San Diego Exposition by Bertram G. Goodhue and Carleton M.

Winslow. By the 1920’s, it became “the style” for Southern California. The acknowledged master of the style was the Montecito architect George Washington Smith.

Spanish Colonial Revival architectural details are summarized below:
a. Form and Mass: Simple, strong one- and two-story volumes with tile roofs of low pitch. Eaves are rarely used and simple tile rakes are typical. Courtyards, colonnades, and patios are used extensively. Mass predominates over openings.
b. Materials and Colors: Stucco with little or no texture is the typical wall material. Red barrel tiles are the preferred roof material. Off-white or creamy beige is the primary color with accents of blue, dark green, ochre, and red.

Wrought iron (black) or wood is used for window grates and balconies.

Limited use of awnings may be designed for sun control. c. Openings: Limited use of arches. Deep set windows and doors. Limited use of simple window grills. Major openings are occasionally accented with raised or molded pediments. French doors are typical. Simple vent holes in walls are common.

3. American Eclectic
Reminiscent of the American Folk and Ranch-style housing, homes designed in the American Eclectic style are deﬁned by the use of wood. The use of wood is an integral element of classic design and suggests permanence, craftsmanship, and warmth.

American Eclectic details are described below:
a. Form and Mass: Prominent in this style of architecture is the gable roof form, which is generally pitched from 5:12 or greater, and broken by dormer windows. Decorative wood trusses, shingles, and round attic vents are used at gable ends to accentuate the gable form.
b. Materials and Colors: The use of siding, wood railings, gable-end millwork, trim surrounds, fascias and shutters, helps to create a feeling of established richness and timelessness reminiscent of Colonial America. Roofs are to be composed of composite, ﬁre-resistant shingles. Asphalt shingles are prohibited.
c. Openings and Details: A distinguishing feature of this style is the asymmetrical front porch. A front porch provides a roof over the main entrance and a semi-private place to sit and enjoy the outdoors.

4. Craftsman Bungalow
The Craftsman Bungalow style was inspired primarily by the work of the Greene Brothers who practiced in Pasadena from 1893 to 1914. These homes feature low pitched gable roofs, exposed roof rafters and decorative braces under gables, porches with roofs supported by square columns and wood clapboard, stucco, and stone exteriors. Craftsman architectural details are summarized below:
a. Form and Mass: Low pitched gabled roofs with porches, either full or partial width with roof supported by square columns, often two-story with dormers and box windows.
b. Materials and Colors: Materials used for piers, columns, and solid porch balustrades are varied. Stone, clapboard, brick, or stucco is all common; they frequently occur in combination. Colors vary with a mix of earth tones with higher accents for windows, piers, and columns. Exposed rafters, rakeboards, and fascia are typically painted complementary colors. Roofs are to be composed of composite, ﬁre-resistant shingles. Asphalt shingles are prohibited.
c. Openings: Craftsman doors tend to be simple three light colonial doors in various conﬁgurations occasionally with sidelights. Windows tend to be single hung with divided lights as grids.

5. Mediterranean
Neo-Mediterranean and Italian Revivalist architecture is a mixing of styles derived from many sources, including southwest adobe architecture, provincial Italian architecture, baroque architecture of colonial Spain and Portugal, and the Pueblo and Mission styles.

Prominent arches over the entry and court yards, colonnades and patios, smooth and rough plaster, and tile roofs are used extensively. Neo-Mediterranean architectural details are summarized below:
a. Form & Mass: Simple hipped roof with ﬂat, symmetrical facades. Many of these homes have a small central wing projected forward from the front facade, or two small wings at either end of the facade with a recessed central block in between.
b. Materials & Colors: Roofs are tiled with boxed eaves. Stucco and masonry veneers are common; wood claddings are never used. Typically an off white plaster is used in a rough or smooth ﬁnish, with quoined accents. c. Openings: Doors, ﬁrst-story windows, or porches commonly have arches above, and entrance areas are accented by small classical columns or pilasters. Common details include pedimented windows and classical door surrounds.

6. Modern Farmhouse
Modern Farmhouse style is the 21st century’s evolution of the traditional Farmhouse style, which merges traditional design with contemporary design elements. Modern farmhouse architecture maintains the farmhouse shape while modernizing it with clean, minimal elements, while utilizing rustic materials in contemporary ways. Modern farmhouse details are described below:
a. Form and Mass: Simple, rectangular shapes with gabled roofs. Balanced and symmetrical massing, generally low and wide. Lines are mostly straight. Roof pitch may vary. Steeper roofs (35-45 degree pitch) may feature no eaves, emphasizing height.
b. Materials and Colors: Natural materials like wood, stone, and brick are preferred. Neutral colors such as white, gray, and brown are the primary exterior colors. Black may be utilized as an accent. Roofs elements to be composed of metal, tile, or composition shingles. Asphalt shingles are prohibited.
c. Openings and Details: Large windows and sliding doors. Exposed beams, rustic wood and industrial metal accents are also common. A large front porch reﬂects functionality and openness.

7. Coastal Contemporary
Coastal Contemporary architecture is a modern interpretation of residential coastal architecture, incorporating contemporary design elements while maintaining a sense of connection to the ocean. This style is characterized by its open ﬂoor plans, large windows, sleek lines, and a focus on natural light and ventilation. Coastal contemporary details are described below:
a. Form and Mass: Simple, rectangular shape with a low-pitched roof, but no ﬂat roofs. Massing is typically horizontal, emphasizing the connection to the ground and the surrounding landscape. Large overhangs and porches provide shade and protection from the elements.
b. Materials and Colors: Natural materials like wood, stone, and metal are frequently used in coastal contemporary architecture. Light, neutral colors such as white, gray, and beige serve as primary colors, while warmer tones like brown and tan can may be utilized as accents. Roofs are to be composed of metal, tile, or synthetic composite or concrete shingles. Asphalt shingles are prohibited.
c. Openings and Details: Large windows and sliding doors are essential features of coastal contemporary homes. Open ﬂoor plans and indoor-outdoor living spaces connect to the surrounding environment.

MASTER PLANNED DEVELOPMENT PERMIT
This booklet accompanies a Formal Application for a Planned Development Permit. It is a program document (or “Master PD”) that communicates the landscape, streetscape and character influences for site layout and common area features, binding the planning areas of Lost Canyons together as a cohesive master plan. It is consistent with, and an extension of, information already presented in the approved Lost Canyons Specific Plan and associated Design Guidelines.

The Master PD is presented as a step in a hierarchy of information depicted in the exhibit below. /gid00049/gid00051/gid00048/gid00036/gid00038/gid00052/gid00052/gid00001/gid00041/gid00042/gid00038/gid00051/gid00034/gid00051/gid00036/gid00041/gid00058/gid00001/gid00039/gid00048/gid00051/gid00001 /gid00046/gid00034/gid00052/gid00053/gid00038/gid00051/gid00001/gid00049/gid00045/gid00034/gid00047/gid00047/gid00038/gid00037/gid00001/gid00037/gid00038/gid00055/gid00038/gid00045/gid00048/gid00049/gid00046/gid00038/gid00047/gid00053/gid00001/gid00049/gid00038/gid00051/gid00046/gid00042/gid00053
