RECOMMENDATION: Adopt a Resolution Approving the Revised River Islands Phase Two Parks and Open Space
Master Plan
CEQA STATUS: The Proposed Project Falls Within the Scope of the Previously Certified Subsequent
Environmental Impact Report ( SEIR) ( SCH No.
1993112027) for the River Islands at Lathrop
Phase Two Project; therefore, No Further
Environmental Review is Required in
Accordance with the California Environmental
Quality Act
SUMMARY:

The Parks and Recreation Commission approved the revised River Islands Phase Two Parks and Open Space Master Plan at the Parks and Recreation Commission Regular Meeting that was held on August 3, 2023. The Parks and Recreation Commission and City staff recommends the City Council adopt a Resolution to approve the revised River Islands Phase Two Parks and Open Space Master Plan to be aligned with the recent changes to Vesting Tentative Map No. VTM 6716. The Woodlands East District was recently modified which rearranged the street layout, lot configurations, and location and size of neighborhood parks N5 and N7, which increased the total Neighborhood Park acreage by 5 acres.

BACKGROUND:

The Parks Master Plan for River Islands is intended to provide a network of master planned parks and open spaces throughout the River Islands development. The park locations along the river provide opportunities to experience the river in multiple ways.

Open spaces are woven throughout at varying scales in order to support an assortment of passive and active recreation. Several types of sports fields are included as well as ample opportunities to enjoy nature and the water's edge.

Pedestrian and bicycle circulation is designed to enable residents to move safely throughout the community. Varying classes of bicycle paths are integrated and promote easy access to open space and extended cycling or running.

In June of 2021, the City approved the River Islands Phase Two Parks & Open Space Master Plan for the River Islands Modified Phase Two Project. A total of 230. 29 acres in the River Islands Modified Phase Two area are devoted to a variety of parks.

REVISED RIVER ISLANDS PHASE TWO PARKS AND OPEN SPACE MASTER PLAN
The parks, in and around the developed areas, include Neighborhood Parks, Community Parks, Linear Parks ( trails), and Pocket Parks. There are also over 272 acres of other open space areas, including levees, drainage swales and protected wetlands.

In May of 2022, the City of Lathrop' s Community Development Director approved a Substanital Conformance request from River Islands for the Woodlands East District.

The application for Substantial Conformance with VTM 6716 was submitted to include various modifications to the road alignments, lot size, and for the two Neighborhood Parks N5 and N7 to be increased in acreage from 5. 39 to 7. 8 and 5. 12 to 5. 4, respectively. This modification increased the total Neighborhood Park acreage of the development by 5 acres and also increased the size of lake L14. Substantial Conformance findings are required to be made pursuant to Condition of Approval # 36 of VTM 6716 when modifications are made to the Vesting Tentative Map. The proposed revised Parks Master Plan will account for the increase in neighbhorhood park acreages.

Additionally, pursuant to Condition of Approval # 118 of VTM 6716, the Phase Two Parks and Open Space Master Plan needs to be consistent with the Quimby Act for required park acreage. Pursuant to the Quimby Act, the project is required to provide approximately 161 acres of neighborhood and community parks. The revised Phase Two Parks and Open Space Master Plan shows compliance with the Quimby Act by providing approximately 167 acres of parkland total.

CEQA REVIEW
Environmental review for the River Islands project as a whole was completed in the certified Subsequent Environmental Impact Report ( SEIR) for the River Islands at Lathrop Phase Two Project ( State Clearinghouse No. 1993112027). The SEIR considered the full range of potential environmental effects of urban development of the entire River Islands Project, including planned parks and open space for the Project.

The project would not produce any new significant environmental impacts, and no new mitigation measures are required. The SEIR specified the mitigation measures needed to reduce potentially significant environmental effects of the River Islands project to a less than significant level. The project is required to conform to these mitigation measures.

RECOMMENDATION:

Adopt a Resolution Approving the Revised River Islands Phase Two Parks and Open Space Master Plan.

The same color- coding is used in the following inventory sheets to enable quick identification of park type. As can be seen in the Phase 1 Parks Master Plan, only some of these facilities are intended to satisfy Quimby Act requirements.

Phase one includes approximately 85 acres of Quimby Act qualified parks and open space. As phase 1 is nat compl tely built out ta date, these spaces are at various levels of completion and planning. Table 2. 2 has been provided to clarify the typology of the open spaces, Quimby Act status, and level of completion. Phase 1 also includes privately maintained and operated facilities that service the needs of the community such as Islander' s Field, and Sunset Point/ the Boathouse.

CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
PHASE 2 PARK SYSTEM GUIDELINES
The following chapter provides a review of parks and recreation guidelines and planning as they pertain to this phase of development at River Islands. This chapter reviews standards and trends in parks and recreation usage, design guidelines, and sustainable practice which will inform a basis of de5ign for the master planning of this park sysiem.

3. 1 TRENDS IN PARKS
Health Trends
In its " Healthy Parks Healthy People" guide, the National Park Service specifically mentions that connection to local parks will help children " lead healthier, happier, more fulfilled lives" in addition to connecting them to natural resources. Efforts such as these by th National Park Service and others by the State and local entities have made the dialogue surrounding health and parks mainstream. It is now widely acknawledged that increasing exposure to nature and exercise encourages physical and mental health far users of all ages. River Islands enthusiastically integrates this concept into its development by encouraging recreation throughout all aspects of the development. Best practices for parks and recreation development include maximizing opportunities to engage users in creative forms of exercise. TY e focus must be on engaging the entire community to participate more actively in parks and recreation. Parents and grandparents engaged in active pu suits will likely encourage the same values and habits in children and youth. Communities with varying demographics must feel comfortable using their public parks and recreation system. Existing cultural and hobby- related community groups provide a desire to participate in a number of activities such as little leagues, futbol clubs, etc.

Current trends show an increase in including opportunities for community gardens. The positive impact of gardening is far- reaching and proves to be beneficial for all members in the community. Community gardens support a sense of community pride and build connections amongst neighbors. They provide the opportunity for people of different cultures to share and build upon cultural connections from farming to food.

Level af Service
National Parks and Recreation organizations, including the National Recreations and Park Association, began to scale back from issuing naiional standards for facilities level of service per population about twenty years ago. Rather it was deem d apprapriat that level-of-service slandards should be determined by individual municipalities and tailored to the unique needs of each cily. 5inc the 1975 Quimby Act ( California Government Code § 66477) was passed, cities and counties in the state of California have had the power to establish land dedication ordinances and require that developers contribute in one of several ways to dedicating land for park improvements. Quimby Act standards include dedication of 3- 5 acres per 1, 000 residents in a given jurisdiction to ensure adequate park land is developed along with housing construction. While five acres does not constitute a maximum allowable park acreage, it does represent in the Quimby Act the maximum park acreage per 1, 000 residents that may be required for developers.

The City of Lathrop has further defined these acreages by requiring three ( 3) acres of Community Park per 1, 000 resitlents and two 2) acres of Neighborhood Park per 1, 000 residenls, Per the City's General Plan, minimum acreages apply to the sizes of indivitlual community and neighbohood parks, The minimum size for a community park is 15 acres, the minimum size for a neighborhood park is 4 acres.

RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN I? CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES

3. 2 PARK DESfGN GUIDELINES
Each park, regardless of size, provides varying unique services to target user groups. The following section categorizes parks by size antl summarizes the types of amenities typical of each park typology. For clarity and consistency, these categories reflect those faund in khe Phase 1 Parks Master Plan and the Neighborhood Development Plan: Community Park, Neighborhood Park, Pocket Park, and Linear Parks. The following typology sections provide an overview of each type of park within the River Islands park and open space system and include typical features which may be appropriate for the separate categories.

Recreation Gaals
River Islands echoes the recreational goals of the City of Lathrop by embracing the following:

Provisions for diverse recreational spaces and opportunities that can support music, dance, arts and crafts, sports, drama, nature study, games, special events, and educational learning activities; provisions for opportunities regardless of an individual' s age, religion, etncic background, economic status, sex, or level of abilities;
opportunities for fostering of leadership skills in the community through safe outdoor environments that allow for social interaction, creative expressions, and community involvement;
options tor year- round engagement in active and passive recreation whether programmed or not; and, education of the community on how to recreate in positive and community building ways.

Community Parks
Community parks often incorporate a variety of recreational programming to provide active and passive recreational opportunities for all. Most residents should be able to access a community park within/ z to 1 mile from their home. An ideal Community Park connects residents to outdoor recreation options, fosters public growth and establishes collective identity. Per the City of lathrop, community parks are primarily intended to serve the needs of organized sports and active recreation.

Community Parks are recommended for development on land greater than fifteen ( 15} acres; exceptions to the this are acceptable but require approval from the Cily. The service area for Community Parks is measured as Yz mile from the boundaries of the park, approximately 10- 20 minute walk for pedestrians.

Typical features include those found in a Neighborhood Park( see Neighborhood Parks description) with the addition of any number of other features. These may include sports fields( lighted and unlighted depending on programming), sport courts, concessian s(ands, restrooms, and amphitheater or performing arts facilities, nature education opportunities, splash pads or other water-play featur s, dog parks, and fitness courses. The design may also include areas for specialty athletics and recreation. Each design will attempt to provide the highest level of accessibility and safety possible ior the benefit of the community and the for the park' s continued succ ss.

Unique to River Islands, community park space also includes miles of non- motorized levee trails that circle the developm nt providing safe access to anywhere within the development. lnese parks are located near schools to maximize recreational space and programming. These open spaces may also include storm water quality features and facilities accessory to the park.

On- site parking facilities are important within community parks to service patron heavy activities that typically occur in these parks.

During the design phases of each community park, the necessary number of parking stalls to accommodate users will be identified based on specific park amenities included in the design. The number oF parking stalls will vary at each park site.

Neighborhoad Parks
Neighborhood parks serve as an extended back yard for local residents and provide both passive and active recreation opportunities.

An ideal Neighborhood Park connects residents to outdoor recreation and increases residents' sense of ownership of their own community. Neighborhood parks are generally a minimum of four acres and are recommended far new neighborhoods as amenities that may be accessed wilhin a 5- 10 minute walk.

Neighborhood Parks are recommended for development on land greater than four( 4) acres. The design of each park will tak into 13 I RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
consideration the unique needs and demographics of the neighborhood within which it is placed. Each design will attempt to provide the highest level of accessibility and safety possible for the benefit of the community and the for the park`s continued success. Parks should be as centrally located as possible within new developments, and not located along high speed roads.

Neighborhood Parks typically include a mixture of active and passive recreational opportunities and more variety of amenities than pocket parks. Playground structures, fitness equipment, and shaded benches and/ or table are typical. BBQ facilities may be appropriate, and provision of waste stations ( trash, recycling, and dog waste) will help support maintaining a clean neighborhood.

Fenced dog parks located within neighborhood parks are designed to serve communities within the immediate neighborhood viciniCy, The dog parks should be strategically located near levee access points to encourage pedestrian use between parks and levee irail.

Open lawn areas large enough to provide spaces for youth team sport practices are encouraged. Sports courts are also appropriate and maybe include bocce, horseshoes, volleyball, basketball, or multi- sport courts.

Pocket Parks
Pocket Parks are geared toward serving residents within the immediate adjacent neighborhood. lhe standard measurement ta determine park service coverage is measured as a quarter- mile radius from the park border, which is roughly a 5- 10 minute walk. The park design should consider the unique needs and the demographics within its service radius. Each design should attempt to provide the highest level of accessibility and safety possible for the benefit of the community and for the parks continued success. Parks will be as centrally located as possible within new developments, and not located along high speed roads.

Pocket parks typically include a mixture of ackive and passive recreational opportunities. These are essentially extended" backyards" of the neighborhood and so provide play opportunities as well as social space for residents. Typical features include, fitness equipment, shaded benches, and tables. BBQ facilities may be appropriate, and provision of waste stations( trash, recycling, and dog waste) will help support maintaining a clean neighborhood amenity. Pocket Parks may also support community garden initiatives. Pocket parks do not qualify for Quimby Act credit.

Linear Parks
linear parks can be designed for multiple functions and purposes. They may function to connect park spaces with safe non- motorized paths that can be used by individuals and families to navigate the network of trails and parks while avoiding automobile traffic. Th y may be a combined vehicle and pedestrian parkway, they may even act as a buffer between residential and commercial ar s, or combine storm water conveyance infrastructure with non- motorized trails. In general, these Uails also encourage pedestrian movement throughout the community while improving visibility and increasing observant" eyes" on the community. linear parks typically include a mixture of active and passive recreational opportunities, but with less amenities than neighborhood parks. Typical features include fitness equipment, benches, and tables. linear parks do not qualify for Quimby Aci credit.

3. 3 SUSTAINABILITY
There is a common misconception that sustainable building alternatives are inherently more expensive than traditional planning and building practices. In a 2009 survey by the National Recreation and Park Associa[ ion, Parks and Recreation leaders noted concerns about keeping up with funding environmental improvements while struggling with budget cuts and reductions in water supply.

Fortunately, water- saving technology and practices have improved such that conforming with state- mandated water usage restrictions is now widely achievable across even the most arid parts of California. Integration of modern irrigation equipment and selection of low- water using plant material will save funds on irrigation water for its parks as well as demonstrate to residents the accessibility of low water using landscapes.

RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN ( 1 CMAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
Sustainability practices are being incorporated into all River Islands parks development. Best practice guidelines outlining the potential strategies that should be included are listed below.

Implement Low Impact Development( lID) stormwater management technology into designs. Vegetated swales capture all water on site and clean it prior to discharging it into the many lakes within the community. The lake water is then used to irrigat th many public apen spaces.

Install hardy, native and adapted plant varieties, avoiding invasive or water- intensive plant varieties.

Recycled water is being used with all irrigation systems to the maximum extent feasible.

Central control irrigation system controllers utilizing weather- based sensors, flow sensors, master valves, and point source irrigation help to minimize over- watering and avoid catastrophic losses of water due to breaks and vandalism.

Consider incorporating community gardens to foster community ownership of park space and educate the public about food security.

3. 4 SAFETY AND SECURITY
The most important aspect of monitoring and providing safe parks and open 5:
space is maintaining an existing partnership with municipal law enforcemenl. v law enforcement agencies provide " boots on the ground° throughout parks and open space assets, and are therefore uniquely able to advise on f`
the unique needs and proven methods for various locations. Parks will be designed with security in mind. Similarly, surveillance cameras located in k y " -
particularly problematic areas may be the best option for certain locations.

A varieCy of wireless, cloud- based security camera technology is currently , available to streamline installation and monitoring of the equipment. local " law enforcement feedback will be central to any decisions related to security at public parks.

The most widely recognized set of best practice standards relating to safety in parks are Crime Prevention mrough Environmental Design ( CPTED} principles include:

Natural Surveillance s-- , - dn.

F
The overall goal of CPTED is the idea that a persan will be less likely to m,,. ,, commit a crime if there is risk of being seen. This principle encourages " see and be seen" quality in public spaces.

New parks will, when feasible be designed such that there are buildings or roads fronting all sides of the park for maximum surveillance.

Where feasible homes and businesses should Face toward the park.

Design and maintain safe pedestrian routes to the park and clear lines Il I ', , of sight from these route5 into major activiry zones within the park.

Encourage neighbors to keep an eye on the park by keeping nighttime lighting pleasant and non- obtrusive and by enforcing hours or park usage to avoid nuisances that could cause neighbors to close doors and windows facing the park.

Where feasible use pleasant, dimmer lighting rather than bright, blinding lighting to avoid creating the excessively dark areas that form just outside the reach of the bright lights.

Security cameras may be installed on a case- by- case basis as deterrent to crime and vandalism.

Where feasible, use of motion sensor lighting to alert others when movement in the park is registered.

This CPTED principle encourages use of creative access control using pathway alignment, landscape/ topographic features, signage or other features to direct the flow of user traffic, rather than traditional but intimidating mechanisms such as fences and wire.

I I RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN CHAPTER 3; PHASE 2 PAF K SYSTEM GUI[ I.IN° r
Avoid using control mechanisms such as barbed wire fences. This aesthetic supports the perception that the facility is dangerous.

A combination of eyes- on- the- park, sufficient lighting and patrolling, and other measures may be used where possible.

Incorporate clear, bilingual signage a[ the major pedestrian entrance( s) to the park. This signage may include information about park hours, maintenance/ littering, and emergency contact information.

Avoid landscape features that create blind spots and prevent adequate surveillance.

Select plant materials to groundcover height( less than 2') and maintain tree canopies to a minimum of 6' above ground level.

Keeping the 2'- 6' visual range open will increase surveillance capabilities and reduce perceptions of possible criminal activity areas.

TerriCorial Reinforcement
Use of visual cures, such as consistent types of pavement, plant materials, or signage to encourage specific usage of park space and to delineate public/ private divisions is an important part of CPTED. In the case of public parks, this territorial reinforcement will:

Encourage community ownership of and presence at parks.

Use varied plant materials to encourage activity in some areas and to discourage unwanted activities.

Suppon the formation of community service group adoption and maintenance programs.

Mainten ncP
Maintenance is of high importance of CPTED safety guidelines. Consider the" broken window" theory, which is the theory that poorly maintained properties will breed criminal activity. Well- maintained places indicate that there is regular human presence which monitors the site and that the community cares about that park, which can deter criminals and deviants from that space. River Islands is dedicated to consistent maintenance practices:

Dedicated maintenance staff to low- hanging maintenance needs, including regular clean- up of litter and graffiti.

Adequate staff and funding to maintain and prune trees and shrubs. This is important in order to keep the trees healthy and make the parks safer and cleaner without excess dead landscape material.

Scheduled periodic repairs of site amenities such as benches, tables, playground equipment, barbeque' s and garbage receptades.

Scheduled regular maintenance of ball field surfaces where the field is" closed" to repair and replace turf/ clay as needed.

Regular interaction with City staff who interact with scheduled user groups. Coordinate with City Staff as well.

Staffing of enough maintenance personnel to visit each park on a regular rotation.

Determined maintenance schedules based upon regular review of park needs with maintenance staff.

Outcome- based maintenance standards for landscape maintenance. Outcome- based standards emphasize " expected end result" maintenance standards.

3. 5 NON- MOTt7RIZED CIRCULATION
Safe pedestrian and bicyclist connections, linking parks, open spaces, and schools throughout the community is a priority. Ta this end, a complex non- motorized circulation system has been developed to accomplish this goal. Tne circulation typology ( as reflected in Figure 4. 5- Phase 2 Circulation Map) consists of elevated( levee) trails, classes 1, 2& 3 bicycle lanes, pedestrian trails, and pedestrian connections. Also included as Figure 4. 6 ( Phase 2 Safe Routes To Schools) is a highlight of the routes which may be used by children to walk or bike to school safely. These typology designations are described below.

Elevateci ( Levee} Traiis
Phase 2 elevated trails are designed to encircle the development following the levees that protect the development from flood events.

They are designed for pedestrians, bicyclists, and equestrian riders. They are also designed for maximum safety by avoiding conflicts with automobile traffic. The trail cross section is 40' wide, with 30' designed for recreational use. The 30' is intended to include a 12' wide paved path with a class II aggregate base shoulder on one side, a class II equestrian trail on the other side( per California State Parks Trail Handbook, and an aggregate base shoulder for other trail amenities. See Section 3. 6 for more detailed trail informalion.

Wilhin the 30' recreational use space other trail related amenities will be included to enhance the value of the trail system. ihose amenities may include features such as: exercise stations at strategic access locations, scenic overlooks, kiosk stations, intcrpretivc/ education signage about the river and surrounding habitat, benches/ tables for resting, bike racks at rest locations, mile markcrs, directional signage, etc.

Class I Bike Path
RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN ( Ih CNAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
Class i paths are paved rights- of- way completely separated from streets. Bike paths will have a '` , t r limited number of cross streets and driveways. These paths are typically shared with pedestrians ' k ;'
b
and often called mixed- use paths. The Highway Design Manual( HDM) standards define these l^, paths as 8'- 10' wide paths with 2' aggregate base shoulders on either side.

Cfass II Bikc Lane
Class II lanes are on- street facilities designated for bicyclists using stripes and stencils. Bike lanes may include buffer striping to provide greater separation between bicyclists and parked or moving vehicles. Bike lanes are the preferred treatment for all arlerial and collector streets on the bikeway network, and not typically installed on low- volume, low- speed residential streets.

The HDM standards define these paths as minimum 4'- 6' wide paths.

Cl ss III Bike Route
Class III routes are streets designated for bicycle travel and shared with motor vehicles. While uVi the only required treatment is signage, streets are designated as bike routes because they are suitable for sharing with motor vehicles and provide better connectivity than other streets.

The HDM notes that minimum widths for Class III bikeways are represented, in the minimum standards for highway lanes and shoulders.

Pedestrian Trails
Pedes rian trails are designated walkways for travel by pedestrian and are not wide enough for a ,, traversing with bicycles. These paths vary in width, but are never narrower than 4' wide.

Pedestrian Connections
Pedestrian connections are designated walkways for travel by pedestrian and typically connect two other circulation path designations. These paths vary in width, but are never narrower than 4' wide.

3. 6 ELEVATED L VEE TRAILS
The River Islands Community has a unique recreational opportunity as it is surrounded with a 200 yr. flood levee that not only protects the community, but also affords the residents a trail system loop longer than most City- wide trail systems. The following paragraphs describe this nearly 18 mile trail system in detail with supporting figures for clarity.

Trail Design
Roughly eight miles of planned levee trails will follow along the top of the levee, generally centered on the center line of the levee alignment. Access point will be provided from the '" development side of the levee at intervals to allow for recreational and maintenance uses. The I
levee trails are maintained and overseen by Reclamation District 2062. The levee trails exceed Highway Design Manual{ HMD) standards for two directional class I trails, with a total paved width of 12' and unimproved aggregate base shoulders totaling 10' in width: 4' wide class II aggregate base shoulder, and 6' wide class II equestrian trail. The remaining 8' wide paih shall be set aside for trail amenities such as overlooks, educational/ interpretative signage, benches and/ or exercise equipment. Figures 3.1 depicts the standard trail design for River Islands levee trails.

I i ( RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
Open Space On Waterside of Levees
The open space areas on the waterside of elevated levees are maintained and overseen by Reclamation District 2062, Th apen space will be maintained to remain in a natural state as much as possible, using hydro- seeding and erosion control methods. Public access is allowed along the 30' wide elevated levee Uails for recreational and maintenance uses. No permanent barriers are planned to restrict public access to the waterside open spaces. However, there will be no recreational trails or amenities in these areas to encourage public access.

Trail Surfacing
The paved section of trail will be constructed of 3" of asphalt over 6" of road base of the trail. Shoulders of the trail will be constructed with 6" of compacted Class II aggregate base. Slopes of the levee will be stabilized with erosion control hydroseed. ll ere will be no ornamental landscape or irrigation systems constructed in conjunction with any permanent levee trails.

Trail Access
The follawing figure highlights pedestrian and non- motorized access to the levee trail, which is crucial to the concept of a walkabl community. To this end, the levees have been designed with multiple access points at strategic neighborhood locations and to facilitate required levee maintenance. In order to accommodate bike groups, equestrian riders, and other groups that require staging areas, strategic aff-site parking locations will be available for access to the trail. These off-site access locations, designated with appropriate signage, won' t necessarily coincide with parks or open spaces, but are more closely associated with trail access points and adjacent uses with adequate parking. These sites may include Community Park C1, the transit oriented development area, the employment center, and the high school site. The transit oriented development area has been identified as a potential equestrian RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN ( 2O CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES

staging area location due to its proximity and access to the levee trail. If equestrian access is required prior to development of the staging area, an interim location can be determined to provide parking, potable water access and other amenities necessary.

3. 7 PLANTING
Plant materials for all parks and open
spaces will be selected from Table 3.1-
Parks & Open Space Plant Species list.

Alternative species may be substituted
A
or added and will be considered on a
project by project basis by the agency
listed in Table 4. 3- Agency Review Table.

Substitutions will be based on the suitability
of the species in terms of similarity of theme,
r
characteristics, size, form, tolerance of
t,,l climatic conditions, soil requirements and
water usage. Plant species have been
selected to mimic existing characteristics
and habitat of the delta waterways and
vegetated agricultural hedgerows. Plant
rr- material selection will strongly consider
Levee trail access points
s the use of drought- tolerant, durable
and long-lived species that give the
3 appearance and imagery of the Delta
Valley. Species are well adapted to the
climatic conditions and soil types typical
of the River Islands Development. large
naturally shaped flowering shrubs species
should be selected to mimic the image of traditional hedgerows typical of the surrounding agricultural regian. Flowering species that create year- round interest are of high preference. Plant and tree selections do not include invasive characteristics, such as: surface roots that can spread, creating trip hazards or that can be destructive to surrounding curbs and walks, species that produce large wind blown seed varieties that become invasive or destructive, varieties that are extremely allergenic and varieties with toxic properties that can be digested by humans or animals.

While fruiting varieties of trees or shrubs may hearken to the true agricultural use of the River Islands project, the use of such species can create maintenance challenges and become problematic as litter creating rodent or pest problems. These species will be avoided except in specific locations where maintenance and control can be exercised. Plant selections have been determined based upon natural shape of species with minimal pruning or maintenance. Shrubs will be used as a screen for fences or utility sUuctures in parks and open spaces. Evergreen plant material as a background is preferable to maintain year-round screening, however, the usage of decorative deciduous plant species is desirable and recommended with care being taken to maintain year- round interest and structure.

Spacing of plant material will be made based upon the species being utilized to create fullness and allow for ultimate growth impact.

The use of traditional " lawn" species and spaces will be limited to parks and public open spaces that encourage active recreational use. When" lawn" species are utilized, varieties will include deep rooting species that use less water than traditional varieties. lhe use and application of" lawn" species will follow the guideline and requirements set for in A61881. Where bio- swales will be incorporated, species will be selected that filter and slow the movement of water from curb inlets to drain inlets. Species will be tolerant of flooding and will be irrigated to maintain an alternative appearance year-round.

Tree varieties have been selected to imitate a rural Delta Valley aesthetic. Evergreen varieties will be used to frame and give dditional interest year- round ro selected areas. Flowering or accent trees will be selected for year-round interest through flower char ct ristics, branching patterns, bark color and shape.

3. 8 SITE FIXTURES
CPTED principles emphasize Ihe impo tance of lighting and overall park a`:, maintenance as contributors to perceptions of safery in parks. Investment in basic maintenance and communiry ownership can change usage pattems for ,, < ,, the better. The following guidelines provide best practices for provision of site " fixtures to support community goals for safe usable parks.

Lighting
Lighting of public spaces should conform to the Illuminating Engineering Society's guidelines. These include provision of sufficient lighting for users to ` discern changes in topography and surface type as well as physical details of approaching figures.

Motion sensor activated security lighting may be considered for all new park construction and existing park renovation as method of security lighting.

Parks may be evaluated for feasibility of dimming or motion sensor activated lighting complaint with California Energy Commission Title 24 on a case- by- case basis.

The Project for Public Spaces emphasizes the importance of not " overlighting" and area. This creates a harsh adjustment for the eye and deeper shadowsjust outside the lighting candle for park users. light fixtures will be installed to appropriate heights for usage. In general, Neighborhood parks will not be lighted. Lighting in larger parks may be 4 $
required for safety and to light sports fields and large areas.

Neighborhood parks may require ligh[s installed to an appropriate pedestrian height, while sports field lighting will require greater height.

LED and solar lights offer benefits of low energy consumption with a minimum of construction disruption to the surrounding area. Solar lighting is appropriate for providing light for pedestrian areas and pathways, no1 w" k• large- scale night lighting of parks.

Though not utilized in most parks, some parks may include decorative ` ', bollard lighting and railings as is found throughout the River Islands Development. Typically these have been used along lake frontages, along River Islands Parkway, and at trailhead pocket parks.

RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN 32 CHAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
Site Furniture
Site furniture should be attractive and inviting, yet durable enough to withstand heavy use.

Site furnishings will be manufactured to include River Islands and City logo to reinforce consistent community sense of place.

Post concise, bilingual signage requiring dog owners to clean up after their animals.

Add dog waster bag dispensers at prominent entrances and at intervals along pedesVian pathways at park facilities.

Ensure all playgrounds receive regular safety inspections by a Certified Playground Safety Inspector( CPSI) Fixtures should be selected that will discourage lying down. Handrail- divided or curvilinear benches are options.

Site furniture and other fixtures should discourage skateboarding and activities in non- designated areas.

Select fixtures that will not create visual obstructions or potential blind spots which could impair surveillance.

Provide trash receptacles at locations that may be easily monitored and emptied by maintenance staff.

Park signs will include River Islands logo and City of Lathrop logo to reinforce the commitment to the community.

Site furniture will be approved by City. Drinking fountains should include an option for dog watering stations where appropriate.

3. 9 CONNECTIVITY
Connecting parks to their users is an important piece of increasing community investment and use of parks facilities. Best practices typically involve locating new parks centrally within a neighborhood or adjacent to other community amenities, such as schoots or community centers, in order to increase visibility and use. RI ernately, locating walkable streets and bicycle paths to connect parks with other community hot spots provides alternative access for users who cannot or do not prefer to drive. The same efforts may be made to align public transportation stops with parks, in an effort to coordinate parks and trail heads adjacent to public transit.

In the case of River Islands, geographically adjacent amenities such as schools, town center, lakes, and the rivers are opportunities for establishing walkable, bike- able connections. A non- vehicular option to navigate these sites and others within the community might encourage users to walk or bike between natural antl cultural amenities firsthand rather than driving between each. stablishing and utilizing levee trails and connecting ihem to park locations helps establish a non- vehicular connection in River Islands.

Easy pedestrian and non- motorized access to the levee trail is crucial to the concept of a walkable community, Multiple nFf- site parking options will be available for access to the trail for those who need to travel to an access point for vehicle or horse off-load, An equestrian staging area is proposed near the transit oriented area due to its ample space and access to the levee trail. These offsite access locations, designated with appropriate signage, may be included at Community Park C1, the transit oriented development area, the employment center, and at the high school site. r, .,

3. 10 ACCESS AND INCLUSION
ADA and geyond Planning for inclusion
Trends in park development nationwide are beginning to include varied recreation opportunities such that all members of a community may enjoy public recreation facilities. It is standard best practice to comply with all local and federal guidelines for universal accessibility in public spaces per the Americans with Disabilities( ADA) regulations. New projects and retrofits to existing parks and facilities must seek to include all members of the community. In addition to complying with ADA standards for basic accessibility, park designs may include standards from the Caliiornia State Parks Accessibility Guidelines in order to increase accessibility to its facilities for all users.

Recreation amenities such as walking paths may include signage and wayfinding for persons with visual impairment, while play areas may include accessibility options for caregivers with varied levels of physical ability. Play areas should include solid impact- attenuating surfaces in order to ensure a safe path of travel for all users.

Univcrsal Design and Sacial Inclusion
In more recent years, park features have moved toward including universal access, social inclusian, and sensary integration to includ everyone. Incorporating these elements increases the parks' ability to attract many unique users and increases the functionality of th amenity. Parks and recrearion amenities which encourage participation by all residents and visitors, regardless of physical or mental ability, demonstrate investment in the public.

RIVER ISLANDS PHASE 2 PARKS AND OPEN SPACE MASTER PLAN ( 3 CNAPTER 3: PHASE 2 PARK SYSTEM GUIDELINES
Playground areas provide children space to develop essential emotional, social and physical skills. Therefore, these spaces should include elements appropriate for supporting all facets of childhood development in a safe environment. Cutting- edge studies of children and nature suggest a myriad of benefits in integrating opportunities for spontaneous learning with natural systems into playgrounds.

Examples may include non- programmed areas consisting of varied topography and surface materials, planting of trees within the playground space, flexible play space edges to encourage play to extend to other natural areas of the park. As a valuable experienc in childhood development, nature play may be explored as a signature resource to be developed.

I
Social equity in parks refer to a person' s ability to access health and wellness benefits associated with using the park. Universal d sign enables groups in society who struggle with physical or mental abilities to fully access and utilize parks and recreational spac s. The following six areas of park design contribute to creating socially inclusive spaces with universal accessibility and sensory integration.

1. Facilities: parking areas, pathways, restrooms, public buildings, and access to water. 2, Parking: provide more than the minimum ADA requirements for parking spaces. Provide accessible parking throughout the park and located near inclusive play areas. This provides numerous access points available to all users.

3. Pathways: Exceed ADA width guidelines Wider pathways allow for easier group access and multiple wheeled devices like wheelchai s and strollers.

4. Restrooms Locate restrooms near ball fields and inclusive play areas. Include family restrooms large enough to house a full- size changing table, and large enough for a caregiver to attend to a full- size adult.

5. Splash Pads: Access to pools and water areas can benefit individuals with different disabilities. Splash pads are a great way to pravide easy access to wa er. Actuato s should be planned for locations and heights that are accessible.

6. Playgrounds: Children with disabilities are one of the largest under served minority groups in our nations. 8.9% of children between the ages of 3 and 21 years old have a disability. Of these, approximately 1. 1% will have a physical disability, 1. 1% will have a sensory disability, 19.1% will have a communicative disability, 11. 2% will have a social/ emotional disability, and 53.9% will have an intellectual disability. Additionally, 2. 2% will have multiple disabilities and 10.1% will have chronic health impairment such as cancer. Disability is often misconstrued as inability to experience play because of limitation form impairment. With over 16% of the local population of I I I

children 5 and up having some sort of disability, and over 27% of the local population aged 18 and under, the need for a place to play together regardless of physical or mental limitations is evident. When feasible and when budgets allow socially inclusive and sensory integrated play principals as noted below will be used.

Comprehensive and Balances Sensory Play opportunities: Sight, Smell, Sounds, Touch, Taste, Interoceptive, Vestibular, and Proprioceptive.

Cozy spaces: Areas designed to escape sensory overload and re- engage after self- regulalion.

Unitary System Impact Attenuating Surfaces: For unimpeded access to recreation Shade Play: Areas must have ample shade to provide respite from heat.

Diversity: Provide diversity in play opportunities that exceed ADA minimums ( i. e. types, materials, grasping requirements, level of difficulty, elevated vs ground level)
Cognitive Simplicity: Play spaces should be easy to navigate with recognizable landmarks and wayfinding.

Social Play Opportunities: For social interaction and play that promote multi- users.

Intergenerational Play: Activities that encourage multiple generations to play together and interact.

Fencing: Some children on the autism spectrum and with disabilities have a tendency to bolt from the playground. lhe playground should be fenced to keep children from running onto nearby roads, canals, and/ or other hazards.

Allergens; Selecl plant species that will be plant near playgrounds and parks that produce low levels of allerg ns and ar not irritant to skin when touched. The Ogren' s Allergy Scale or OPALS Scale can be used to determine this, Playground Surfacing
The primary safety surfacing system used in the River Islands Development is rubberized surfacing.

4. 3 DISTRIBUTION OF EXISTING PARKS AND FACILITIES
Current maps of River Islands parks were studied based upon established measurements of user walkability and recommended park programming to determine new park locations for Phase 2. Smaller neighborhood parks service the immediate surraunding neighborhood with the minimum being '/a mile radius up to '/z mile radius. Larger community parks have a larger service radius with the range of'/ z mile to 1 mile radius.

Figure 4.1 shows most areas within Phase 1 and Phase 2 are covered within the'/ a mile radius, and all areas are serviced within z mile. As can be seen all areas within Phase 2 fall within the '/ z mile service range for neighborhood parks, most areas falling within a '/ a mile radius.

4. 4 PARK AMENITY BENCHMARKS
The National Recreation and Park Association ( NRPA) has long been an organization relied on for guidelines and instruciion regarding best practices for parks and open spaces. In 2019 the NRPA published an Agency Performance Review document providing benchmarks for suggested amenity counts based on residents per square mile. Table 4. 2 reflects the number of amenities proposed for phase 2 based on the NRPA' s published recommendations and Table 4. 4 reflects which parks they are located in.

4. 5 PROPOSED PARKS & OPEN SPACE SYSTEM
The parks and open space system depicted in this chapter were developed following multiple meetings and reviews of park system components with City of Lathrop staff. In order to clearly identify the components of the system maps were created and are included in this chapter as follows:

4. 6 PRELIMINARY PARK CONCEPT PLANS
In order to identify intended locations of required and additional park elements throughout the development, preliminary concept plans have been developed for all Quimby Act related community parks and neighborhood parks. In addition examples of potential pocket parks, and linear parks have also been shown which will be built by River Islands, but not intended to be built in order to meet Quimby Act requirements. All concepts are simple concepts to convey basic park ideas and are not to be misconstrued as final designs. As each neighborhood is developed the park designs will be revisited and adjusted to meet specific neighborhood, budget, and recreational needs. Any changes to the park locations, acreages, or amenities must be appraved by the City of Lathrop prior to construction. Modifications to park locations, acreages and/ or planned amenities shall be reviewed and approved by the City of Lathrop prior to construction. Amendments to this Parks & Open Space Plan shall be reviewed and approved by the City of Lathrop.

4. 7 CITY OVERSIGHT & DEVELOPMENT PROCESS
There are many types of open spaces and recreational facilities incorporated into the River Islands Phase 2 development. While the development is located within the City boundaries, portions of these open spaces are owned by Reclamation District 2062 RD2062) and all parks and open space are maintained by the River Islands Public Finance Authority ( RIPFA). lY e following table has been provided to clearly delineate the required reviews to be completed by each agency, for each open space type.

The following descriptions describe the review typology listed in Table 4. 3.

Comprehensive Review- Comprehensive review refers to plan review for construction level improvement plans. Prior t Improvement Plans, a Site Plan for Neighborhood Parks and Community Parks shall be reviewed and appraved by the City and Parks& Recreation Commission. These plans are typically reviewed and signed by the Public Warks Department, Parks Recreation Department, and the Lathrop Manteca Fire District. The City may determine which departments are required far review based on a project by project basis.

Courtesy Review- A courtesy review of construction level improvement plans by the Public Works Department for open spaces owned and maintained by RD2062 and/ or RIPFA but not in the public right of way.

Utility Only Review- A review by the Public Works Department of construction level utility plans only, for spaces owned and maintained by RD2062 and/ or RIPFA.

Subject: Findings of Substantial Conformance with Vesting Tentative Map 6716 for Proposed Lotting Amendments within the River Islands, Phase 2, Woodlands East District.

Dear Mrs. Deil' Osso:

The Community Development Department has completed its review of your request for a Finding of Substantia! Conformance with the River Islands, Phase 2 Vesting Tentative Map ( VTM) No. 6716 for the proposed lotting amendments illustrated on the Woodlands East District Lotting Summary Comparison map, and further detailed in the Woodlands East District Unit and Acreage Changes table ( enclosed). My findings and support of your substantial conformance request are detailed below.

As noted in your substantial conformance request letter of April 22, 2022, condition of approvaf number 36 of the Phase 2, VTM No 6716, established specific findings required for the Community Development Director to administratively determine whether or not Final Maps are in substantial conformance with the Vesting Tentative Map. The condition states that:

The Final Map shall be in substantial conformance with the approved Vesting Tentative Map as determined by the Community Deve%pmenf Director. Deviations from the approved Vesting Tentative Map that are not considered in substantial conformance include but are not limited to the following:
a) Changes fo the proposed location ofland uses not otherwise consistent wilh the adapted West Lathrop Specific Plan ( WLSP) land use designation; b) Changes to the proposed densities of a developmenf area fhat are in excess of the density permitted for that specific area as designated in the WLSP; c) Significant changes to the size and locafion of open space and recreation areas within a devetopmeni area that would result in less open space and recreational areas compared to the amount required to satisfy that deve%pment area's Quimby Act requiremenfs; d) Significant modifications ( such as to alignment or location) to major roadways, such as to major collecfor or arterial roads where a precise plan line has been adopted; Changes that would result in a new significant, adverse, unmitigated environmental impact, or a significant increase in any previausly identified impact.

Administrative review and approval of the requested amendments for substantial conformance is provided for by Condition 36 above, and detailed in the following findings:

May 5, 2022
Future final maps based on the proposed lotting amendments to VTM 6716 will remain consistent with the adopted WLSP land use designations. The most notable modification to the VTM is the increased size of Lake 14, necessitating the relocation of Neighborhood Park 7 immediately north and adjacent to the levee. These changes da not affect the designated land uses or require amendments ta the WLSP, as schools, lakes, and parks are permitted uses in residential zones and are not designated by separate or unique land use designations.

Future final maps based on the proposed lotting amendments to VTM 6716 will remain consistent with the adopted WLSP land use densities. None of the proposed modifications will substantially increase or decrease development densities, and none are in excess of the density otherwise permitted.

The proposed changes to the size and location of Neighborhood Parks 6& 7 are not significant in that the changes do nat result in less recreational acreage and the parks remain in generally the same locations. More specifically, Neighborhood Park, N7 is relocated immediately narth and adjacent to the levee from its current location, and increases in size fram 5. 12 to 5. 4 acres. Neighborhood Park, N6 remains in the same location with an increase in acreage fram

7. 10 to 7. 8 acres. Being larger and in the same general loca#ions maintains Neighborhood Parks 6 & 7 Quimby Act acreage requirements and status and definition as Neighborhood Parks.

There are no proposed changes in alignment or location of streets or street types; and therefore there are no changes in environmental conditions.

Overall, the proposed lotting amendments do not create any new environmental impacts or increase the intensity of previously analyzed environmental impacts, and remain within the scope of the certified SEIR, requiring no further enviranmental review. • Processing and approval of future final maps within the Phase 2, Woodlands East District as illustrated on the Woodlands East District Lotting Summary Comparisan Map and at the densities and acreages provided for in the Woodlands East District Unit and Acreage Changes Table, are in substantial conformance with VTM 6716, and will continue to be subject to the existing conditions of approval far VTM 6716 as originally adopted. This substantial conformance appraval is contingent upon the provision of amended pages for each of the assoclated Phase 2 documents in order to formally document these actions, prior to final maps wlthin the Waodlands East District. We appreciate your continued coordination and assistance with staff on the development of your project. If you have any questions, please do not hesitate to contact me at ( 209) 941- 7266.

Subject: Substantial Conformance Findings— Phase 2 Vesting Tentative Map No. 6716 Woodlands East DisU•ict of River Islands)
Dear Mark:

As a follow up to our March 8, 2022 and March 17, 2022 letters requesting substantial confo mance of revised lotting patterns in Phase 2 of River Islands, we are providing this tetter to finalize our request for the Woodlands East District and provide final exhibits as reviewed and commented upon by you and your staff.

Specifically, Exhibit" A" has been updated to reflect an updated lotting pattern that resolves the City' s issues with additional roadway intersections at River Islands Parkway, the relocation of the neighborhood park within Village 4, the expansion of Lake 14 and other issues. We sre also providing an updated Exhibit" B" that summarizes the final changes in acreage and numbers of dwelGng units for the Woodlands F,ast District. Exhibit" C" is a revised parks and parks service area e chibit that reflects the new neighborhood park location. We acknowledge that we must update the Phase 2 Master Parks Plan to the reflect the changes proposed, including the 2, S acres of pa• kland that may not be included with the various efementary school sites. However, Exhibit" C" still reflects the 2. 5 acres of park at schoots, since it is included in the existing, approved Phase 2 Master Parks Plan. We witl be siting an additional neighborhood park in or near Woodlands and will provide details as to that park( ocation with the proposed update/amendment to the Parks Plan.

In order to move forward with this administrative approval, the City witl require that the none of the conditions listed in condition of approva136 to VTM 6716 exist with regards to our proposal. I have provided a brief e: cplanation below as per condition 36( shown in red) that provide evidence that the findings for noi- conformance will not be met:
