Section 1.0 - Executive Summary

LAS POSITAS COLLEGE DESIGN GUIDELINES

1. EXECUTIVE SUMMARY

INTRODUCTION

Las Positas College is a 147-acre community college campus located in Livermore, California. The college has been granted $217 million in Measure B Bond funds, and with that, the campus is set to expand greatly over the next 5 years. With increased sur-rounding development, such as Shea Homes to be built directly adjacent to campus, the LPC understands the need for the col-lege campus to become integrated with the local community. In addition, Las Positas College seeks to create a campus that: promotes active student life, provides increased educational opportunities, is a comfortable and attractive environment and works toward greater sustainability.

In April 2006, the Chabot-Las Positas Community College District retained the services of Royston Hanamoto Alley & Abey (RHAA), landscape architects and environmental planners, and Carducci and Associates, Inc., landscape architects and irrigation design-ers - to lead the process of creating Design Guidelines for the LPC Campus.

This set of Design Guidelines has been created to provide a framework for future development that recognizes the needs of a growing campus. With development projects underway, such as the multi-disciplinary instructional building and aquatic center, Las Positas College will use the Design Guidelines to ensure that all future endeavors remain consistent with the principles of the college and key design considerations.

REPORT ORGANIZATION

The Design Guidelines report begins with a Project Overview, which lists the overall goals of the Design Guidelines, and follows with a review of Site Organization, a crucial consideration of view corridors to be enhanced, vehicular and pedestrian gateways and a hierarchy of pedestrian circulation paths.

Next, the Design Guidelines defi ne the over arching Landscape Themes on campus, and a more refi ned look at Landscape Elements at key zones, including treatment of gathering spaces and suggested specialized gardens.

The section titled Site Elements outlines specifi c design guidelines for components which visually and functionally unify the campus, such as paving, lighting, site furnishings and signage.

Lastly, discussion of sustainable principles is followed by a compre-hensive set of technical design guidelines which address: paving, planting, stairs and ramps, irrigation, grading and drainage.

Section 1.0 - Executive Summary

PHILOSOPHICAL PRINCIPLESSeveral over-arching principles apply to all of the recommenda-tions in the Design Guidelines.

- Enhanced Learning Environment

- A Sustainable Campus

- Campus Core as: relaxed, inviting, comfortable and beautiful

- Campus as Focal Point of Local Community

DESIGN GUIDELINESThese guidelines are intended to provide a standard for future development and the criteria necessary to ensure cohesive site design and campus planning for future developments, along with improved sustainable functionality.

The guidelines ensure that future projects will be consistent with both the Las Positas College Mission Statement and the Facilities Development Plan. These guidelines also suggest that all future development be designed sustainably in accordance with green building practices.

The Design Guidelines defi ne design parameters for the follow-ing elements:

• Site organization to include views, gateways and circula-tion.

• Landscape Themes that have contextual relevance and help to visually organize the campus.

• Landscape and site elements to include planting, irriga-tion, paving, site furniture, plaza areas, streetscapes, parking lot design, lighting, and signage

• General and specifi c guidelines to ensure campus-wide sustainable practices.

Finally, the Master Design Guidelines provide direction in the areas of signage, wayfi nding, and lighting in the Civic Center.

The diagrams featured in the document reinforce and clarify the set of design guidelines and provide a visual record of design decisions. Also, included in the Appendix are both a Plant List and set of Technical Details, which will inform future site design on campus.

The attached Summary Table outlines the Design Guidelines, with more details in the accompanying full report and Product Information Sheets.

Section 2.0 - Project Overview and Background


2.0 PROJECT OVERVIEW

2.1 IntroductionLas Positas College is located in the city of Livermore, in what is called the Tri-Valley Region, north of Highway 580 and 40 miles southeast of San Francisco. The 147-acre campus site once supported an agrarian lifestyle made up of vineyards and cattle ranches, but today has shifted toward residential and commercial development. The growth of the college is refl ective of the overall growth of the Livermore area, which is home to some of California’s fastest growing business and scientifi c industries.

The college is situated amid scenic rolling hills which frame the campus to the north and east. The topography of the campus is characterized by a slope from east to west. Directly south of the site is future residential development.

Las Positas College began as an extension center of Chabot College in 1963 and soon expanded to its current location in 1975. It has since developed into a fully accredited comprehensive institution of over 8,000 students, serving the ever-growing community of the Tri-Valley Region. Most of the buildings of the campus are more than 25 years old.

In 2004, a Measure B Bond was passed to provide Las Positas College over $217 million for renovation and expansion (see below). With improvements already underway, including the construction of a new multi-disciplinary instructional building, the need for a comprehensive set of Design Guidelines is immediate.

LOS POSITAS COLLEGE DESIGN GUIDELINES

PROCESSThe process of establishing Design Guidelines began with site visits to Las Positas College by landscape architects from Royston Hanamoto Alley & Abey and Carducci & Associates where potential gathering spaces and view corridors were documented, students’ use of the campus was observed, and perimeter conditions were noted.

Along with familiarization with past planning documents, the landscape architects formulated general concepts of design and presented them to the District at a user group meeting. In response to the feedback, a follow-up meeting addressed more specifi c options for various design guideline considerations, such as site furnishings and lighting.

The decisions made in user group meetings determined the Design Guidelines explained in this document.

2.2 Design Guidelines Goals & ObjectivesThe central aim of the Design Guidelines is to bring people from the perimeter of the college to the campus core. This is achieved by blending the campus into its natural environment, both thematically and through educational use of adjacent open space, and encouraging a philosophy of sustainability that enhances the learning environment.



OBJECTIVES

The following key objectives will apply to all of the recommen-dations in the Design Guidelines.

Enhance Campus IdentityThe recently passed Measure B Bond will allow the campus to expand and provide the opportunity to create a distinct identity as a unique learning environment. New development projects will be integrated into the existing campus to provide continuity. Design Guidelines will establish the campus identity, infl uenced by the character of the surrounding natural landscape and will use the campus gateways to be a strong expression of the iden-tity put forth.

Make the Campus an Attractive EnvironmentThe Design Guidelines will call for the following implementations to create an attractive learning environment: enhancement of natural surroundings, appealing and low-maintenance plant palette, continuity of site furnishings, and landscape design which addresses problems such as wind and heat.

Develop an Appropriate Landscape ThemeThe landscape theme will offer a balance between the natural surrounding environment, characterized by native plant species and agricultural landscape, and the park-like, botanical land-scape of traditional campus design. In addition, the layout of landscape themes will reinforce site organization.

Improve Public ImageClearly defi ned gateways that are consistent with the overall campus character will be one of the key guidelines to establish a strong public image. Also, the college will reinforce its image as a modern, technology-driven learning environment through updated site furnishings and application of current standards in sustainable design.

Enhance Learning EnvironmentDesign Guidelines will incorporate learning opportunities into site expansion and improvements in the following ways: pro-vide outdoor classrooms intimate in size for focused learning, use agricultural parts of the campus (small vineyards) as an ed-ucational opportunity, promote physical education along with native plant knowledge through trail system, and fi nally, to use all implemented sustainable design as a vehicle for education.

Low Maintenance, Sustainable CampusLas Positas College is dedicated in “fi nding new solutions and improving old practices” through implementation of sustainable design. In accordance with the Facilities Development Plan (May 2005) chapter on sustainability, the Design Guidelines out-line specifi c objectives: LEED certifi cation, water conservation, stormwater management, reducing heat islands and prevent-ing light pollution.

DESIGN GUIDELINES

The Design Guidelines will also defi ne design parameters for the following elements:

Site organization to include views, parking locations, hierar-chy of circulation, gateways and nodes/gathering spaces.

Landscape Themes

Relationship of buildings to adjacent outdoor spaces

Landscape and site elements to include planting, irrigation, paving, site furniture, open space, streetscapes, parking lot design, lighting, and signage.

POTENTIAL FUTURE DEVELOPMENT SITES

A key component of the Master Design Guidelines will reevalu-ate and analyze previous development site recommendations in order to create a comprehensive framework upon which sub-sequent designs will be based.

Issues to be discussed for site development include the following:

Pedestrian Circulation and AccessParking LayoutVisual ImpactsPossible Development SitesSite utilities

Based on the above, the Guidelines will outline site design crite-rion that the Las Positas College District can use for current and future projects.

2.3 Facilities Development Plan, 2005In response to increased residential and commercial develop-ment adjacent to Las Positas College, the Facilities Develop-ment Plan states planning objectives for the college based on research and a forward-thinking approach.

With development comes increased vehicular and pedestrian traffi c. The Plan proposes that this infl ux of people to the college be channeled into a vibrant “Campus Hub,” framed by open space, athletics and access points at the perimeter.

The goal is that Las Positas College become a focal point of the local community, and form a strong relationship with its neigh-bors. A key objective of the Facilities Development Plan is to create “A Model Sustainable Campus” (College Mission State-ment, 2004). This will be achieved through the implementation of specifi c sustainable design and practices. The goals of the plan are as follows:

Campus Sustainability. This includes a responsible use of re-sources and low mainetance and operating costs.

LEED Silver Certifi cation Equivalent. This includes using renew-able energy sensibly, reducing all forms of pollution and con-serving water.

Superior Teaching and Learning Environments. This will, in turn, enhance the quality of student life.

Building Forms and Landscape to Infl uence Climate.

Safe and Functional Campus.

2.4 Measure B Bond Program, 2004Measure B, a Chabot-Las Positas Community College District capital improvement bond measure, was passed in March of 2004, allocating $217 million to Las Positas College toward reno-vation and expansion, based on growth projections consistent with the increased population of the Tri-County Region. The bond program is designed to provide facilities which will serve current and expected enrollment (enrollment is expected to increase from 8,000 to 15,000 students in the next few years). Modernization and expansion of both buildings and site is re-quired to meet said demand. The following campus planning documents outline criteria for application of Measure B funds.

DESIGN STANDARDS MANUAL, 2006

The Design Standards Manual describes the standards generic to the Measure B Bond program. Specifi c requirements for the

9



Chabot-Las Positas Community College District can be found in the District Design Guidelines (see below).

The purpose of the Design Standards Manual is to provide a framework to ensure consistency for new and rehabilitated parts of the campus. The manual provides technical standards that architects and engineers will be expected to meet or exceed. The standards include:

Program. Establish project limits based on approved master plan.

Sustainable Design Standards. Meet LEED Silver Level via: water conservation, facilitating use of public transportation, and maximizing renewable resources.

Landscape Design Standards. Continuation of existing pal-ette of the campus, as it applies to: planting, paving, light-ing and site furnishing; and modernization of the irrigation system.

DISTRICT DESIGN GUIDELINES, 2006

The District Design Guidelines are a district-specifi c set of techni-cal standards to ensure consistency of design for all new and rehabilitated parts of the campus. The policy calls for:

Consistency of parts (for reorder) from the District InventoryHigh level of product quality and workmanshipUniform and simplifi ed maintenance scheduleUpdating of old materials consistent with new materialsOverall aesthetic consistency apparent at both campuses

SECURITY MASTER PLAN, 2005

The Security Master Plan has been compiled by CATALYST, se-curity specialists. The section on lighting in the report is most applicable to the Design Guidelines discussed in this document. Lighting to be designed to incorporate general principles of se-curity lighting, such as:

Integrate light into the total security system and thereby fa-cilitate the effectiveness of security devices or procedures.

Illuminate objects, people and places to allow observation and identifi cation and thereby physically reduce criminal concealment.

Reduce the fear of crime for the innocent by enhancing a perception of security.



CATALYST’s Night Survey found insuffi cient footcandle levels along non-primary paths. The study revealed that the fi rst prior-ity for lighting improvements is parking lots. In fact, the Security Master Plan suggests parking lot areas be upgarded al least to IESNA standards.

Landscaping considerations address tree and shrub mainte-nance. All plant material to be maintained so as not to obstruct the ability of light to create a clear line of sight. This means that shrubs to be trimmed to below 3 feet and trees trimmed up to 7-8’.

Section 3.0 - Site Organization


3.1 IntroductionAs the local community continues to grow, student enrollment increases and the campus expands, planning for effective site organization will be vitally important for the future functionality of the campus. This section deals with points of access, pedes-trian and bicycle circulation and both vehicular and pedestrian gateways.

In order to bring people from the perimeter of campus into the campus core, the following set of design guidelines outline a hi-erarchy of pedestrian circulation paths. Once on campus, the arrangement of pedestrian paths direct visitors to distinct views enabled by the campus setting and topography.

3.2 View CorridorsThe location of the Las Positas College campus allows for great views. Because it is situated at the northern edge of the Liver-more Valley against the rolling hills, including topographic change within the site, the campus offers views west toward scenic vineyards and south across the Livermore Valley to dis-tant hills.

The following design guidelines ensure that the key views be maintained and enhanced through future development, see Figure 2: View Corridors, for specifi c view point locations.

DESIGN GUIDELINES

- Tree planting at key viewpoints should be handled with care. Views to the west (toward vineyards) and views south (across the valley) should not be obstructed with large tree species, but rather, views should be framed by smaller trees. (A thorough tree planting master plan is required).

- Location and treatment of nodes/gathering spaces (see Section 5.2) shall be coordinated with viewpoints, listed be-low.

SECTION 3.0 SITE ORGANIZATION

Several important views are listed below and indicated on the View Corridors Diagram:

1 Viewpoint between tennis courts and ball fi eld at highest point of the site offers views down through the central bou-levard of campus, and south across the valley to the distant hills.

2. A key node/gathering space at a high point – views of both the vineyards westward and the Livermore Valley south-ward.

3. This viewpoint from within campus is still high enough al-low views of vineyards westward as well as a view through the central campus corridor south to the demonstration vine-yard.

4. Views from within campus include: the rolling hills to the im-mediate north and through the campus entry corridor south across the Livermore Valley.

5. View from existing recreational fi eld, future amphitheater, with an unobstructed view of the rolling hills of the campus’ north side open space.

6. At the lowest point of the site, there are still important views. To the west is the small demonstration vineyard at the cam-pus entry and to the south is the view across the equestrian trail and Shea homes.

7. Upon arrival at the central pedestrian gateway of the campus, views are impressive across the valley toward the distant hills.

8. The pedestrian gateway at the athletic complex offers a great view of the demonstration vineyard to the immediate south, with the Livermore Valley beyond.

3.3 Site Circulation

Las Positas is committed to enhancing the travel experience for pedestrians, bicyclists, and transit users to ensure that alternate modes of transportation are successful in reducing car traffi c. The Alameda County Congestion Management Agency has outlined a plan that underscores this commitment with repeat-ed emphasis on the importance of pedestrian links and con-nections between neighborhoods, shopping centers, employ-ment centers, schools and recreational sites.

In accordance with the sustainable values expressed in the Facilities Development Plan, access to the entire campus by way of foot paths, walkways and bicycle routes is critical to the site’s success as a hub of the local community. Plans for the Los Positas College campus includes a comprehensive network of walkways. Currently the site lacks several critical pedestrian links.

It is also becoming increasingly important to provide access to the college from adjacent neighborhoods, the campus can po-tentially serve as a neighborhood park for an increasing number of local residents. Currently access to the site from adjacent areas is limited and could be improved.

ENTRIES AND GATEWAYS

Gateways are important access points that establish the char-acter and image of the campus upon arrival. Vehicular and pedestrian gateways will have different treatments and are de-scribed below:

Vehicular Gateways. The Los Positas College District has agreed that vehicular gateways be indicated by a strong scheme con-sisting of planting and signage, instead of structural elements such as pillars and archways.

DESIGN GUIDELINES

- Planting shall be organized, of varying heights and variety, offer fl owering color, and be easy to maintain on a frequent basis.

- Planting shall be designed to not obstruct signage.

- Signage shall be consistent with all campus signage (see Section 5.12) with appropriate lighting.



Pedestrian Gateways. Pedestrian gateways double as nodes/gathering spaces, and as such, treatment of nodes as seen in Section 5.2 applies. The pedestrian gateways also are places that offer views, which shall be enhanced by the design.

DESIGN GUIDELINES

- Perimeter of node defi ned by vertical structure: wood trellis with concrete base 6” above fi nish grade – or GreenScreen.

- Seating to include: concrete seatwall (see Section 6.3)

- Planting, lighting and signage consistent with vehicular gateways.

PEDESTRIAN CIRCULATION

Pedestrian circulation (see Figure 3: Pedestrian and Bicycle Cir-culation) will be organized into two categories:

Primary Paths. Major paths include walkways connecting sur-face parking lots with pedestrian gateways. And within cam-pus, the major pedestrian path consists of a prominent Boule-vard, which is a central spine that connects the entire campus along a series of gathering spaces.

Secondary Paths. Secondary paths serve to connect the major paths with buildings and connect buildings with eachother.

DESIGN GUIDELINES

- Sidewalks along primary and secondary streets are pre-ferred site-wide in order to strengthen connections between buildings and outdoor features on site. Signage and lighting should also be included. Sidewalks will improve overall pe-destrian safety and access to parking lots.

- For all major pedestrian routes: poured-in-place, sawcut concrete to be used, at a minimum of 12’ width.

- For all secondary pedestrian routes: poured-in-place, saw-cut concrete to be used, at a minimum of 6’ width.

- Boulevard treatment shall include: specialized tree plant-ing and lighting. At nodes along the Boulevard, concrete slab base will be present under specialty pavers to allow for vehicular access along the entire length of the Boulevard.

BICYCLE CIRCULATION

The Alameda County Bicycle Plan of 2005 proposes bike routes to allow students commute by bike to Las Positas College im-proved access (see map).

The following guidelines will improve bicycle circulation and ac-commodate increased bicycle usage on the Los Positas College campus while reducing adverse effects on the environment.

DESIGN GUIDELINES

- Bike racks will be installed at all pedestrian gateways.

- To keep Las Positas College compliant with LEED Silver Equivalent: “Locate bicycle storage facilities within 50 feet of the frequently used entrances.” Bike rack allotment shall be in compliance with LEED requirements according to 5% of new building occupants.

- Los Positas College and other primary streets should have striped bike lanes and should meet all city, county and state standards.

- Bicycle access via multi-use paths, such as the open space trail network, is encouraged. Care should be taken in design-ing these paths to avoid user confl icts and safety problems.

- Coordination with relevant county agencies, City of Liver-more and interested citizen groups is encouraged.

However, this 2005 plan shows a proposed bike trail through the Shea Homes development adjacent on the south side of campus, which continues southeast toward Livermore city center.



PUBLIC TRANSPORTION

The Livermore Amador Valley Transit Authority (LAVTA), other-wise known as “Wheels” provides easy access to the Las Positas College campus, via bus line 12 which connects to the Dublin/Pleasanton BART station.

Also, The Altamont Commuter Express (ACE) runs east/west to Livermore center and stops on campus. The bus stop for both bus routes is at the Parking Lot ‘D’ circle.

DESIGN GUIDELINES

- LPC is committed to enhancing public and alternative modes of transportation to and from the campus. Future transporta-tion planning efforts should emphasize options other than the use of private vehicles.

- Currently, there is one bus shelter. As student enrollment increases (it is expected to double in the next 5 years), more bus shelters are encouraged on the campus and should be designed specifi cally for the needs of the student popula-tion.

- To avoid deterrents for students using public transportation, LPC shall encourage LAVTA to post current schedules and maps at all bus stops on campus and provide shelters that adequately protect riders from inclement weather.

TRAIL SYSTEMS AND CONNECTIONS

A trail system on the Las Positas College campus is an important addition to the standard pedestrian paths because: a trail sys-tem will allow students and faculty to take advantage of the open space to the north of the campus and to provide oppor-tunities for both physical education and botanical education of California native plants (see Section 4.2 on landscape themes).

DESIGN GUIDELINES

- A trail system that incorporates a loop in its alignment is highly encouraged, as suggested by the Physical Education Department.

- Coordination will be required to provide a trailhead con-nection at the intersection of the campus trail system and the equestrian path planned for the Shea Homes community at the southern edge of the site. Other connections to existing or future adjacent trail systems, wherever possible, is encour-aged.

- The trail shall be constructed using decomposed granite. Decomposed granite will allow infi ltration, and is in keeping with the informal aesthetic of the California Native Landscape theme.

Section 4.0 - Landscape Themes


SECTION 4.0 LANDSCAPE THEMES

4.1 IntroductionEstablishing appropriate landscape themes on campus is im-portant because it sets up a framework that will determine sub-sequent landscape design decisions. The Las Positas College District has decided upon an arrangement of landscape themes, per Figure 4.

Consistent with the philosophy of the LPC’s Mission Statement, the college will promote sustainability through continuing native plantings at the campus perimeter, and transitioning into an at-tractive park-like landscape theme at the campus core.

4.2 Campus as Extension of Native California Landscape

Grounds Manager Tom Fuller outlines in Sustainable Landscapes at Los Positas College (see Appendix), the 20-year practice of planting native California trees and shrubs along the north perimeter of campus. Enhancing the natural surroundings by continuing this native California landscape theme will promote sustainability and offer educational opportunities for students along the proposed trails.

20 LAS POSITAS DESIGN GUIDELINES


DESIGN GUIDELINES

- Decisions about specifi c plant species be based on: Sus-tainable Landscapes at LPC (appendix), Plant List (appendix) and consultation with LPC Grounds Manager.

- Species similar to pure natives (species native to Mexico, Central America, the Meditteranean and Africa) may be used because they are conducive to the Livermore environment. Like native species, non-natives will not be irrigated. Plant identifi cation will make clear which species are CA natives and which are not.

- Plant identifi cation will be installed along trail alignment: botanical name, common name and location of origin.

4.3 Campus as Park and Botanical GardenAt the center of campus, the landscape theme will be a com-bination of park setting and botanical garden. The Las Positas College District agrees that the core of the campus should be lush and have shade trees, to help protect against the heat typical of the summer months, and more formal in nature than the native California plantings at the campus perimeter. The planting scheme will consist of non-native (exotic) plant species that require irrigation.

DESIGN GUIDELINES

- Decisions about specifi c plant species will be based on: Sus-tainable Landscapes at LPC (appendix), Plant List (appendix) and consultation with LPC Grounds Manager.

- Plant species will be non-native and irrigated, but will not require excessive watering.

- Plant species will be low-maintenance and have a clean, compact appearance.

- Key areas will be designated as rose gardens. Roses are already present on campus and the Livermore Valley climate is conducive for growing roses. Specifi c planting schemes may be used, such as a Heritage Roses theme.

- Plant identifi cation will be installed along trail alignment: botanical name, common name and location of origin.

- Opportunities for specialized plant palette will be possible at key locations (See Section 5.2, Specialized Gardens).

EXAMPLES OF BOTANICAL LANDSCAPE THEME AT CAMPUS CORE

4.4 Campus as Agricultural Landscape

The agricultural history of the Livermore Valley offers inspiration for establishing the Los Positas College campus as a unique setting which refl ects its past. The rolling hills of Livermore were used for cattle grazing, then cultivated into vineyard and orchards.

With a strong viticulture curriculum at LPC, the Facilities Develop-ment Plan calls for two vineyard demonstration areas, showcased at point vehicular gateways.

DESIGN GUIDELINES

- Areas specifi cally designated as agricultural will be limited to (2) vineyard demonstration areas, as indicated in the Facilities Development Plan.

22 LAS POSITAS DESIGN GUIDELINES


- Agricultural areas to be cultivated and maintained by Viti-culture Department.

- Possible integration of agriculture-inspired landscape fea-tures (such as, olive tree grove) will be considered for addi-tional locations on campus.

Section 5.0 - Landscape Elements


SECTION 5.0 LANDSCAPE ELEMENTS

5.1 Introduction

This chapter discusses how landscape elements such as planting schemes and gathering spaces/plazas can create speces for students, staff and faculty to use, which are comfortable, beautiful and occasionally, educational. The landscape elements reinforce the landscape themes, discussed in the last chapter, adding new dimensions to the planting palette, such as opportunities for specialized gardens.

The following landscape elements are meant to by fully incorporated with the site elements (Section 6.0), such as paving, lighting and furnishings, to create an integrated approach which will be evident on campus.

5.2 Planting Schemes

The following planting scheme categories outline the specifi c guidelines which correspond to the Master Tree Planting Plan, see Figure 5. The species selected are suggestions, based on: existing plant material on campus, Shea Homes and City of Livermore streetscape plans, desirable foliage color and tree canopy cover for specifi c areas on campus, and input from the LPC User Group, especially the Grounds Department.

STREETSCAPE AND VEHICULAR GATEWAYS

Because Las Positas College has opted for an informal approach to vehicular gateway design, the planting scheme is important as the main way of differetiating and emphasizing gateways. The character, scale and abundance/variety of species chosen for each gateway shall be consistent with its prominence and functional importance within the campus as a whole.

DESIGN GUIDELINES

- Create vehicular gateways using: planting, signage and lighting

- Varying features, such as specialized plant selection, to be utilized in order to differentiate and identify various gate-ways.



- Planting scheme selected at each gateway shall correspond to the landscape theme within which it falls, i.e., gateways along the north part of the loop road will be planted using the plant palette of the transitional landscape zone - both native and botanical species.

- Formality of planting scheme to be consistent with the over-all importance of the gateway. For instance, Collier Canyon gateway, is the campus’ most formal and gateways along north edge of campus least formal.

- Refer to City of Livermore streetscape plans for the new street, Campus Hill Drive - LPC tree and shrub selection adjacent to City streetscape shall be consistent and/or complimentary in scale, color and shape of plant material.

- Intersection at Collier Canyon and LPC Loop Road:Flowering trees and shrubs to be utilized. Where possible, ex-tend planting areas across the road. Incorporate bioswales, as indicated in the Technical Section 9.0, wherever possible.

- Secondary Parking Gateways along South Loop Road: Utilize fl owering shrubs at small gateways to help identify points of entry and aesthetically link campus exterior with interior.

- Main Student Services Loop:Develop formal tree arrangement of Quercus agrifolia (per Master Tree Planting Plan diagram) to emphasize formal qual-ity of entry loop, i.e., formal and equidistant alignment of trees along road.

- Shea Homes Gateway (Campus Hill Drive):Extend agricultural expression into gateway planting scheme, such as orchard tree plantings. Also, incorporate bioswales wherever possible as part of gateway and campus identity.

- Athlectic Fields Gateway:This gateway is at an important vantange point for views. All tree plantings to be consistent with guidelines outlined in Sec-tion 3.2 View Corridors.

- Childcare Gateway:Utilize fl owering shrubs and trees.

- Performing Arts Gateway:This vehicular entry to the Performing Arts center shall have a specialzed planting treatment consistent to differentiate the gateway. The specialzed planting scheme at the gateway shall relate to that of the Performing Arts plaza space.

- Additional Gateways along North Edge of Loop Road:California native plant species to be utilized, per categorized plant list, see Appendix. Generally informal planting scheme utilized.

25



NODES AND PEDESTRIAN GATEWAYS

Treatment of node spaces are detailed in the following section, 5.3, Gathering Spaces / Nodes. The planting scheme of these spaces contributes to the purpose of the nodes: to provide protection from the elements, comfortable seating and unobstructed views. The trees and shrubs selected shall be compact in form, maintained regularly so as not to confl ict with signage and lighing, and trees shall not block views, per Section 3.2 View Corridors.

DESIGN GUIDELINES

- Deciduous shade trees to be utilized wherever possible to pro-mote a comfortabel gathering space: shade protection during summer months and sun exposure during winter months.

- Seasonal color (annual fl owering plants) to be utlized wher-ever possible to showcase node/plaza spaces.

BOULEVARD

The Boulevard will be distinguished from other pedestrian paths by several design implements: paving consistent with primary path circulation (see Section 6.2), campus core lighting which includes bollard and pedestrain pole lighting, and lastly, through plant selection. The Master Tree Planting Plan shows the tree selections along the Boulevard.

DESIGN GUIDELINES

- Develop educational planting concept along Boulevard.

- Educational interpretation can include, for instance, the use of both native and non-native plant species to show plants of a particular continent or region. Interpretive signage shall be utlized wherever such educational planting schemes are implemented (see Signage Section 6.8).

NATIVE PERIMETER

The planting scheme of the Native Perimeter (north edge of campus) is outlined in Section 4.2, Landscape Themes: Campus as Extension of Native California Landscape.



SPECIALIZED GARDENS

Specialized Gardens can be an excellent opportuntiy for the college to: emphasize diversity of educational programs through the garden’s relationship with adjacent departments, provide fundraising and naming opportunities, and to create an aesthetically diverse and stimulating campus core.

DESIGN GUIDELINES

- Where possible, specialized gardens shall relate to adjacent building uses.

- The following suggestions for specialized gardens through-out the campus are opportunites for education, naming and fundraising:

Shakespeare Garden near Performing Arts buildingPoetry Garden near Literature/English DepartmentViticulture and/or orchards near Agriculture Dept.Culinary or Herb Garden near CafeteriaWhimsical, colorful plants with varied textures at CDC

- Additional ideas for specialized gardens which are not de-partment-specifi c:

Fragrant Grarden near high traffi c areasHummingbird and Butterfl y Garden along BoulevardDry Garden to demonstrate sustainabilityBioswale/Biobasin to demonstrate sustainabilityNight GardenPalm Garden botanical display, similar to an arboretum.

TURF PLANTING

Turf planting is generally abundant on campuses due to its reliability, pleasing aesthetics and often functional use as a space for students to sit and gather informally and comfortably. However, Los Positas College should consider LEED principles when allocating area for sod planting in order to remain consistent with the sustainability principles of the college.

DESIGN GUIDELINES

- Concentrate turf planting in high use/traffi c areas.

- Where possible, use signifi cant turf planting in areas most likely to be used by students and faculty for seating/picnicing and possible outdoor class meetings.

- Separate turf and shrubs with concrete mowband, consistent with existing concrete mowbands currently on campus.

- Install sod, not seed whenever possible.

5.3 Gathering Spaces / Nodes

The temperate climate of the Livermore Valley provides a learning environment where students and faculty tend to gather outdoors, for both educational and social congregation. It is important that outdoors gathering spaces - nodes - be designed to be comfortable, functional and in general, a pleasant place to stop and have a seat. These spaces will help to promote a cohesive collegiate community.

As seen on the Site Organization Diagram (Figure 1), the nodes have been placed at points throughout the campus most condusive for gathering. Also, placement of nodes takes advantage of key view corridors.

The primary function of the nodes is to provide space for small and large gatherings in a pleasant environment. The size of the nodes will vary in size dependent upon estimated needs of the space. The larger nodes shall be large enough to accomodate a class meeting.

Nodes are to provide protection from the elements. This includes shade for both heat and rain, and planted screening for wind protection. There are several opportunities possible at any of the proposed nodes:

Fundraising can be achieved by collecting donations for special paving.

Art installations can ideally be displayed at nodes (also a fundraising/donor opportunity).

Water features can be the focal point of a node

If adjacent to a specialty garden, a naming opportunity exists where both the garden and node are identifi ed by a memorable name.

DESIGN GUIDELINES

- At nodes where views are important, follow tree planting instructions, per Section 3.2.

- All paving at nodes shall be asphalt pavers, see Section 6.2. Arrangement/pattern of pavers can vary from node to node.

- Seating at nodes to be concrete seatwalls with recessed light fi xtures in wall.

- Additional seating in large plaza spaces will include tables, chairs and umbrellas (see Section 6.5) Exising gathering space on campus

Campus plaza condusive for gathering

Trees, seawalls, light posts and paving patterns organize the space and provide comfortable functionality.



- Shade trees to be strategically planted at nodes where no existing shade cover exists.

- Utility stub-outs (hook-ups) to be installed for programmatic fl exibility. Utilities need to accommodate: amplifi ers, water and electricity for a coffee cart, etc.

- LPC Public Relations Department to be consulted at onset of site design for all plaza spaces to ensure all fundraising op-portunities be realized.

- If water feature is planned for a node at time of pavement install, proper piping will be required.

5.4 Art and Special FeaturesArt that is appropriate in content, scale and placement for the setting can add a unique character to a specifi c space, and the campus as a whole.

The district agreed that sculptural pieces are the most desirable form of art to be displayed on campus. Also, the District has suggested that some art pieces be sensory elements, such as water features in nodes. Solar-powered water features are preferred due to maintenance and budget issues.

DESIGN GUIDELINES

- All proposed art peices will be reviewed per the Los Positas College district standard review process.

- Any bases required for art pieces will be consistent in ma-terials, construction and appearance with poured-in-place concrete seatwalls (see Section 6.3).

Example of art installation that doubles as seating, UCSF Mission Bay campus


Section 6.0 - Site Elements

SECTION 6.0 SITE ELEMENTS

6.1 Introduction

The character of a college campus is defi ned in large part by the order, consistency and material quality of site elements. These elements should be located in a purposeful and meaningful way. The current development of the campus has evolved without the benefi t of over arching guidelines which bring these characteristics to the site.

The following guidelines provide a reference for future campus development with the intent of unifying the campus spaces, and to enhance the collegiate environment of Las Positas College.

6.2 Paving and SurfacesThe following guidelines are intended to outline the recommended approach to paving treatments and surfaces on the Las Positas College campus. Further discussion regarding pedestrian circulation, path widths and preferred routes can be found in Section 3.3, Site Circulation.

Guideline for ALL Paving Types:DETECTABLE WARNINGSAdd detectable warning paver of contrasting color to meet ADA code (not bright yellow).

PRIMARY PEDESTRIAN WALKWAY SURFACESPrimary walkways encompass most of the circulation on campus. These are the primary routes for students between different parts of the campus, including major walkways through parking lots.

DESIGN GUIDELINES

- Existing sidewalks to be made as consistent as possible in terms of design, materials, color and fi nish.

- The preferred material for walkways is poured in place standard gray concrete with sawcut joints, and with a consistent medium sandblast fi nish.

SECONDARY PEDESTRIAN WALKWAY SURFACESRoutes between primary walkways and between buildings are known as secondary walkways.



DESIGN GUIDELINES

- Existing sidewalks should be made as consistent as possible in terms of design, materials, color and fi nish.

- The preferred material for secondary walkways is poured in place standard gray concrete with sawcut joints, and with a medium broom fi nish.

CAMPUS BOULEVARD WALKWAY SURFACESThe Campus Boulevard is the major pedestrian spine in the center of campus.

DESIGN GUIDELINES

- Existing sidewalks should be made as consistent as possible in terms of design, materials, color and fi nish.

- The preferred material for boulevards is poured in place standard gray concrete with sawcut joints, with a medium broom or sandblast fi nish. Asphalt pavers may be used as accent paving at nodes along boulevard.

GATHERING SPACES/NODESThese areas are special destination places for social interaction, studying, eating, special performances, and special events.

DESIGN GUIDELINES

- The preferred material for these areas is asphalt pavers or Stepstone concrete pavers. Where possible, asphalt pavers and Stepstone concrete pavers should be arranged in a pattern distinct to adjacent pathways to give the nodes their own character.

BUILDING ENTRY PLAZASBuilding entry plazas are areas located in front of primary or visually signifi cant building entries.

DESIGN GUIDELINES

- Concrete pavers are preferred material at building entries.

TRAILS AND INFORMAL PATHSThese areas are noted as informal pedestrian paths at the perimeter of the campus and possible connections to an overall trails system.



DESIGN GUIDELINES

- The preferred material for trails and informal paths is Nature Pave Resin Pavement, see product information sheet, p.92; OR, decomposed granite can be used as an alternative.

Paving materials and site surfaces in any landscape are important as they help defi ne spaces and connections. Surface treatments also signal the importance of an arrival point or building entry and provide students and faculty with a sense of orientation.

At Las Positas College, much of the paving consists of poured in place concrete and asphalt (a few areas with stamped concrete). In general, the quality of paving materials at Las Positas College should be signifi cantly improved and updated. It is preferred, too, that paving treatments and materials be consistent based on function as much as possible as outlined above. This will provide clarity for users fi nding their way through the site.

Asphalt pavers Nature Pave Resin PavementSee product information sheet, page 92.

Standard poured-in-place concrete with sawcut joints. Medium sandblast fi nish for primary circulation and medium broom fi nish for secondary circulation.

Concrete pavers - StepstoneSee product information sheet, page 91.



6.3 Seatwalls and StairsSteps and Seatwalls to be made of reinforced concrete, consistent in appearance with all poured-in-place concrete paving.

DESIGN GUIDELINES

- Steps to be consistent with adjacent paving: sandblasted concrete for primary paths and broom-fi nish for secondary.

- Seatwalls are to be form-fi nish on all edges, except top of seatwall, which is smooth, trowel-fi nish concrete.

6.4 Landscape Lighting

The importance of lighting on a college campus cannot be overemphasized. As discussed in Section 2.4, the Security Master Plan for the college outlines specifi c lighting goals as a direct contributor to actual and perceived campus safety.

Additionally, the family of lighting fi xtures chosen can go a long way in establishing a set aesthetic character for the campus. The Design Guidelines outlined in this document serve to ensure continuity and functionality of all site and landscape elements on campus - lighting is a key component of said continuity.

And lastly, the goals for sustainability stated in the LPC Mission Statement have been considered in forming the landscape lighting design guidelines. Energy effi ciency is promoted and light pollution has been mitigated.

See Figure 7: Lighting Plan for footcandle recommendations.

Seatwalls: poured-in-place concrete with form fi nish sides and smooth trowel fi nish top.

Stairs: poured-in-place concrete, medium sandblast fi nishHandrails: brushed aluminum



Louis Poulsen Lighting/Kipp Post; pedestrian pole light for primary pedestrian circulation. See product information sheet, page 93.

Bega Lighting/Model 8145: pedestrian pole light for secondary pedestrian circulation. See product information sheet, page 94.

GENERAL DESIGN GUIDELINES

- Provide adequate light for safety and security. Two main lighting factors that reinforce a sense of safety and security are adequate horizontal illuminance at the ground for navigation of pathways, and adequate vertical luminance at surfaces such as building forms, building entries, people, signage and planting to provide visual contex

- Use lighting to promote wayfi nding. Illuminate gateways and vertical surfaces to provide context for pedestrians and drivers. Integrate lighting systems with signage. - Address maintenance issues such as standardizing lamp types as much as possible, maximizing accessibility of fi xtures for easier repair and re-lamping, optimizing lamp life, cost, and energy efficiency, and minimizing opportunities for vandalism.

- The scale, form, color, and spacing of lighting elements should be cohesive campus-wide and compatible with the historic design precedents and with the simple, and timeless designs of other site elements such as planting, architecture, and signage. This concept of a “family of fi xtures” should be applied to the major open spaces.

- The Lighting Plan, Figure 7, contained in this section summarizes the overall design approach. Each possible future project should provide smooth transitions between zones of different light intensities. Zones of varying levels of brightness based on the diagram should be implemented. The lighting solution should provide an appropriate balance of light and level of comfort, with the actual quantity of light (i.e. number of footcandles) as a guideline. Special attention should be paid to providing a visually comfortable transition from one area to the next.



PEDESTRIAN POLE LIGHTSThe lighting design approach calls for one treatment for primary pedestrian circulation and another treatment for secondary circulation - therefore, two types of pole lights will be used.

DESIGN GUIDELINES

- Louis Poulsen Lighting, Kipp Post (Cut-Off version), pedestrian pole light with black powdercoat fi nish consistent with other lighting fi xtures - has been selected as District Standard for primary paths. See Product Information page p.93.

- BEGA Lighting, Model 8145,pedestrian pole light with black powdercoat fi nish consistent with other lighting fi xtures - has been selected as District Standard for secondary pedestrian circulation. See Product Information page p.94.

PEDESTRIAN BOLLARD LIGHTSBollard lights to be used along primary circulation, such as the Boulevard, and potential for use adjacent to future buildings.

- KIM Lighting bollard light - Dual Function Luminaire VRS2 with Aluminum Shaft in Black Powdercoat - has been selected as District Standard, see p.95.

RECESSED LIGHTING IN CONCRETE SEATWALLSThe recessed wall lights are to be used in nodes/plazas/gathering spaces where concrete seatwalls are implemented.

- BEGA Lighting recessed wall light - Semi-Recessed with Shielded Light Source in black - selected as District Standard for use in concrete seatwalls, see p.96.

UPLIGHTINGUplighting is to be used for signage and trees. Because of light pollution concerns, uplighting to be kept to a minimum.

- KIM Lighting uplight - Aluminum fi xture, Model #KLV 200/201 in black powdercoat fi nish - selected as District Standard for all uplights required on campus, see p.97.

PARKING LOT POLE LIGHTS

- Existing parking lot pole lights have been selected as District Standard for surface parking lot lighting.

6.5 Site Furnishings

Site furnishings are an important feature on a college campus because they allow for: sociability, fl exibility, outdoor gathering for classes, a refi ned campus character and potentially an opporunity for fundraising.

SITE FURNITURE

Consistent with the overall design approach of the LPC campus, the site furniture is not overly formal, instead opting for a balance of modern, clean lines and traditional forms.

BENCHES- Landscape Forms - Town Square model with black powdercoated peforated metal - has been selected as District Standard for use througout campus, see p.99.

- Landscape Forms - Austin model with ipe wood structure and black powdercoated metal accents in both backless and full-size models - has been selected as District Standard for use as a specialty bench in nodes/plazas on campus, see p.98.

Landscape Forms: Carousel picnic tableSee product information sheet, page 101. Generic Market (cloth) Umbrella

Landscape Forms: Austin bench, for nodes/plazasSee product information sheet, page 98.

Landscape Forms: Town Square bench, standardSee product information sheet, page 99.



TABLES & CHAIRS

Currently, the Las Positas College campus has limited usable site furniture. The User Goups have agreed that the general approach to site furniture is a relaxed, fl exible arrangement of tables and chairs. Moveable tables and chairs are becoming increasingly popular, seen at public gathering spaces and college campuses because they allow for impromptu social gatherings and at the same time, allow fl exibility for students, staff and faculty to sit read alone, if desired.

TABLES- Landscape Forms - cafe table, round perforated Steelhead tabletop with black powdercoat fi nish - has been selected as District Standard, see p.100.

CHAIRS- Landscape Forms - Verona chair, perforated with black powdercoat fi nish - has been selected as District Standard, see p.100.

UMBRELLAS

The User Group has decided that the ability to move the umbrellas is very important, thus ruling out the option of a metal canopy umbrellas which has a long lifespan but virtually no fl exibility because it requires being bolted to the ground. Therefore, the Group has agreed that 2-3 year maintenance of a cloth umbrella will be worthwhile because of its versatility.

- Generic marketplace (cloth) umbrella to be used with use of tables and chairs.

Landscape Forms: verona chairSee product information sheet, page 99.

Landscape Forms: cafe tableSee product information sheet, page 100.



ADDITIONAL SITE FURNISHINGS

The following additional site furnishings are abundant througout campus and therefore, have been selected to be both functional and fi t in with the site furniture selections.

BIKE RACK

The specifi c requirements for bicycle storage for LEED Silver equivalent is outlined in Section 3.3. Bike racks will be installed at building entrances and require a certain surrounding area for occasional bike storage. Their appearance must be consistent with the aesthetic of the other site furnishings.

- Landscape Forms - Pi Rack model, black powdercoated metal - has been selected as District Standard throughout campus. Also, the slender bars of this selected model allow for a Kryptonite lock to secure both the bike frame and wheel to the rack, see p.102.

DRINKING FOUNTAIN

The following drinking fountain will replace existing freestanding drinking fountains and installed as part of future development.

- Most Dependable Fountains, Inc. - Model 450SS and 440DBSS, stainless steel pipe, bowl and bubbler, which meets ADA requirements - has been selected as District Standard thoughout campus, see p.103.

TRASH/RECYCLING RECEPTACLES

The following guidelines indicate both trash and recylcing receptacles selected for use througout campus.

- Forms + Surfaces - Universal Trash Receptacle, 36-gallon round with black powdercoat perforated fi nish, top-opening, without ash option - has been selected as District Standard for all trash receptacles on campus, see p.104.

- Forms + Surfaces - Universal Receptacle, with Recycling Logo, 36-gallon round with black powdercoat perforated fi nish, top-opening, without ash option - has been selected as District Standard for all recycling receptacles on campus, see p.104.



Landscape Forms: Pi bike rackSee product information sheet, page 102.

Forms + Surfaces: trash and recycling receptaclesSee product information sheet, page 104.



6.6 Fences & Screening

The Las Positas College campus has fencing in only a few areas, adjacent to service areas and surrounding athletic fi elds. The design guidelines will establish consistency for all fencing to be replaced or newly installed.

Maintaining and ensuring safety on the campus for all users is the college’s fi rst priority, refer to Security Master Plan for all specifi cs regarding security fencing. In addition, the aesthetics and functionality of fences and screens are important. The college is committed to fi nding and appropriately addressing fencing, screening and access issues with its neighbors to the south, east and west.

DESIGN GUIDELINES

- Black vinyl coated fences are preferred for durability and aesthetics.

- Fencing will be needed at: service areas, Child Development Center and athletic areas. Add black wind screen material to fence where necessary in athletic areas.

- All fences should be planted with shrubs and vines wherever possible.

- Greenscreen is one possible alternative to the standard black vinyl coated chain link. To be used in key areas, such as gathering spaces/nodes, see p.105.

- Screening should be applied specifi cally to service area along northern stretch of the loop road. This will include both black vinyl coated chain link fence and shrub/tree planting in front.

Greenscreen: green trellis as accent fence type for gathering spaces/nodesSee product information sheet, page 105.

Standard fence thoughout campus: black vinyl coated cahin link



6.7 Parking Lots

The parking lots on the Los Positas College campus would value from aesthetic and functional improvements, in accordance with the sustainable values put forth in the Facilities Development Plan. As refl ected in the above design guidelines, the preferred approach today is to return to this idea of highly vegetated park-ing lots.

The District has decided that said vegetation shall be concen-trated into key circulation corridors cutting through the lots and providing organized pedestrian access to the campus. In addi-tion to beautifying the campus, the LPC has an opportunity to demonstrate cutting-edge sustainable design strategies in the campus parking lots. Using bioswales to fi lter run-off from the lots, dense tree planting for shade, and permeable paving to reduce run-off, these sustainable parking gardens could be models for development.

The following are guidelines for parking lot improvements to be applied to all renovation of existing surface parking lots and future built lots.

DESIGN GUIDELINES

- Whenever possible, existing parking lots on the LPC campus should be redesigned to incorporate bioswales to capture and treat run-off on-site. These swales should run in between rows of parked cars and be planted with species specifi cally chosen for their water fi ltration abilities. Future construction of parking lots shall comply with the above.

- Existing parking lots should also be densely planted with shade trees. Tree planting to be concentrated along designed pedestrian walkways, which provide functional pedestrian ac-cess to the campus. Soil fertility and irrigation strategies must be devised in order to promote sustained health and growth of trees in such harsh environments

- Where possible, existing lots should be repaved with per-meable surfaces to reduce stormwater run-off. The Facilities Development plan calls for a plan to mitigate runoff which incorporates parking stalls paved with pervious surface, and drive lanes with standard asphalt (impervious).

- Parking lot lighting should be enhanced for safety. Refer to the Security Master Plan’s section on lighting for further details.

- All new lots on the site should strictly adhere to the sustainable design practices listed above.

- The feasibility of installing solar panels in shade structures over parking areas should be explored.

6.8 Signage and Wayfi ndingThis section addresses existing site signage, a concept for overall site signage and wayfi nding, and signage design guidelines and concepts. Redirecting the main vehicular entrance to campus will require establishing an entrance sign equal in prominence as the current monument at Collier Canyon.

An updated, comprehensive site wayfinding system would substantially improve visitor orientation and enhance the special character of the Los Positas College campus.

DESIGN GUIDELINES

Identity Signage- It will be critical to “label” each public entrance to all campus buildings conspicuously.

- Plant identifi cation signage will be necessary along trail (for native plant identifi cation) and within the campus (for exotic botanicals). Signs to be small-scale, consistent with most arboretum plant identifi cation signage. Signs to include: botanical name, common name and location/region of origin.

Directional Signage- New signs should be placed at the Isabel Road entrance to campus, and along the loop road to direct visitors to the parking zone nearest the building entrance that leads most directly to their destination.

- Wherever possible, directional signs should have a maximum of three listed destinations - limiting listings ensures drivers have enough time to read and react.

- Secondary directionals are used where slower speeds permit readability of smaller copy. Generally, they also display fewer destinations.

- Pedestrian-scale wayfinding should be provided along the paths of travel along the specifi ed boulevards and from parking lots to appropriate building entries, and throughout the campus. - The cap height (the size of a capital letter measured vertically) for primary directional signs along LPC Loop Drive should be 4” to 4.5.”

Existing building identifi cation signage

Exisitng directional signage



Informational Signage- This includes all regulatory signage, such as handicap access signage, etc. Whenever possible, informational signage to be as consistent as possible with campus signage (typeface, color palette, etc.)

lnterpretive Signage- Interpretive signage to be used at visual displays of sustainable implements for education purposes, specifi cally, signage near bioswales in parking lots to explain environmental benefi ts of best management practices such as these.

- Interpretive signage to be employed along trail for educational opportunities: botanical information pertinent to native California plants, understanding of agricultural history of the site, etc.

ADDITIONAL CONSIDERATIONS

Pedestrian Orientation MapsA few strategically placed maps will give many visitors a helpful overview of the site. (Some people cannot make the association between a scaled representation and the physical world. Wayfi nding should therefore not rely exclusively on orientation maps.)

Potential map locations include the transit stop on Civic Center Drive, the Administration Building and Hall of Justice parking lots, and key pedestrian nodes at the Marin Center. These maps should include only the destinations and information necessary to guide most visitors. The more complex a map, the more intimidating and confusing it can be.

Compatibility with other AgenciesPublic transit systems typically have their own, distinct signage and graphics, together with standards for their use, and this may be the case for LAVTA. However, signage should, if possible, have site-specifi c structural supports and/or “framing.”

Overall SizeSize as necessary to display the copy at the indicated cap height and to provide an adequate border zone all around.

Sign panels should generally be wider than they are high to minimize multiline messages. 4’6” is an optimal overall height. The lowest copy on a sign panel should be 1’0” to 1’6” above fi nish grade to keep the copy within a driver’s line of vision and

to prevent being blocked by ground cover.

MaterialsAluminum is the industry standard for most sign fabrication. It is lighter and easier to work than steel, doesn’t rust, and is only moderately more expensive.

A spray applied paint fi nish is also standard; powder coating and baked enamel are more durable and more costly. Porcelain enamel is most expensive, but non fading and essentially impervious to graffi ti. A primary sign can be a monolith or a sign panel on a base structure like precast concrete. Secondary signs are usually post and panel signs.

ChangeabilityMost destinations at the Las Positas College campus are unlikely to change over time. Where change is a possibility, the use of modular directional signs which simplify copy updates should be considered.

PlacementVehicular directionals should be placed as close to the street as possible without disrupting sightlines or interfering with underground utilities.

Placement should also take into account adjacent trees, shrubs and ground cover.

Irrigation heads should be directed away from sign panels to avoid the buildup of alkaloids from repeated spraying.

LightingAll principal wayfinding features should have dedicated external illumination unless ambient light levels are high enough to provide the necessary visibility.

Design ConsiderationsAll components of the hierarchy should employ the same typeface and utilize the Las Positas College color palette, and all components should reflect a common design vocabulary.

That design vocabulary, however, should not mimic the Los Positas College architecture. Instead, it should be compatible in a general way, using curved forms to soften massing, and horizontal rather than vertical proportions whenever possible.

Section 7.0 - Building and Architecture

7.1 Relationship of Buildings to Outdoor SpacesOVERVIEWAs indicated in the Las Positas College Master Plan, the campus will be growing signifi cantly over the next 5-10 years, including the construction of many new buildings. This Design Guidelines document deals primarily with site and landscape concerns, yet this chapter addresses the design relationship between the new buildings and adjacent outdoor spaces. In general, it is encouraged that new buildings incorporate design of outdoor space to compliment both the landscape design and architecture.

DESIGN GUIDELINES

- Paved plaza areas with ample seating at the main entrance to new buildings to be provided.

- Utilize special paving type, Stepstone pavers, at building entrance, per Paving Diagram, Figure 6.

- Locate plaza spaces in wind-protected areas wherever pos-sible, using shelter trellises, for example.

- Consider views when locating plaza spaces and tree plant-ing around plaza spaces: views from building interior to be considered equally to views from the building exterior.

SECTION 7.0 BUILDING & ARCHITECTURE

Section 8.0 - Sustainability


7.1 Introduction“The Las Positas mission is one of achieving academic, social, eco-nomic and ecological sustainability,” Facilities Development Plan, 2004. The following design guidelines outline the key principles of sustainable site and landscape design, to ensure that future campus development is consistent with the values expressed in the college’s mission statement. (More technical considerations are addressed in Section 9.0)

7.2 Water ConservationThe two main ways to conserve water through effective land-scape design: planting drought-tolerant plant species that thrive in the local environment and installing a modernized, automated irrigation system which is designed specifi cally for the site.

DESIGN GUIDELINES

- The native planting palette at the northern perimeter of campus (see Landscape Themes diagram, p.x) shall consist of California native species wherever possible. Drought-tolerant, non-natives will be considered.

SECTION 8.0 SUSTAINABILITY

Example of aesthetic quality of native planting scheme



- Exotic plant species at the campus core (see Landscape Themes diagram, Figure 3) will be irrigated, but should not required excessive irrigation.

- All plant lists for future development projects to be reviewed by Grounds Maintenance Department for compatibility with existing list of plants known to succeed in the Livermore Val-ley environment.

- Use Toro Weather Track or similar system that tracks the weather daily and varies the water quantity accordingly. Slopes and type of landscape (groundcover, etc.) can also be inputed into the system to determine exact water quantities. (see Section 9.0 for irrigation specifi cs).

7.3 Reducing Effects of Heat IslandsThe Livermore Valley reaches high temperatures during the summer months (May through September). As such, reducing the harmful effects of the “heat island effect” will include both abundant planting of shade trees and paving that is light in color and pervious wherever possible.

In addition to providing a campus that provides comfortable protection from the sun for students and faculty, the following design guidelines are consistent with the LEED standards for Silver Equivalency.

DESIGN GUIDELINES

- Shade trees are to be planted according to the planting schemes outlines in Section 5.0, with species selection made from the plant list (appendix).

- Intense heat effects due to large, asphalt-paved surface parking lots to be mitigated by shade tree planting and planted rows along walkways, see Section 6.9. - According to Credit 7.1: Landscape and Exterior Design to Reduce Heat Islands, Non-Roof of LEED standards, “Provide shade (within 5 years) and/or use light-colored/high-al-bedo materials (refl ectance of at least 0.3) and/or open grid pavement for at least 30% of the siteÆs non-roof impervious surfaces, including parking lots, walkways, plazas, etc.” This means that credit can be earned by using paving that has an emissivity rating of 0.3 or greater and/or providing shade cover for 30% of paved surface.

Planters display native California plant species, with opporunity for botanical signage for educational purposes.

7.4 Stormwater ManagementManaging stormwater runoff through a sustainable approach to site planning will include best management practices, such as the capture and infi ltrating of runoff by pervious and vegetated surfaces, in accordance with the Facilities Development Plan.

Best management practices such as bioswales are becoming increasingly prevalent and, if properly designed, can be an attractive landscape feature throughout the year. Refer to Technical Section 9.0 for specifi cs on stormwater management implements.

DESIGN GUIDELINES

- Impervious surface shall be kept to a minimum, with planting areas breaking up large spans of impervious paving wherever possible.

- Grading plan to allow for drainage into infi ltration and reten-tion areas, as indicate din Technical Section 9.0.

- LEED standards state, “Use an open-grid pavement system (less than 50% impervious) for a minimum of 50% of the park-ing lot area,” in order to earn Credit 7.1.

7.5 Light PollutionAlong with residential and commercial development planned for land adjacent to the campus, the Las Positas College campus is committed to reducing light pollution to preserve views of the night sky.

DESIGN GUIDELINES

- Light fi xtures to be ‘cut-off’ (full cut-off, where possible) to limit the amount of light emitted into the sky, and focus light on the ground.

- Limit quantity and intensity of uplighting for trees.

- Limit intensity of uplighting for signage.

9.1 IntroductionAs a complement to the previous chapters, this section is a discussion of the technical elements of the major landscape elements at the Las Positas College campus. The guidelines of this section provide the parameters for the construction of high quality, long lasting and low maintenance projects that further the objectives of the LPC. The technical guidelines provide the designer tools to create a cohesive campus design and help resolve the inherent technical issues related to working at the LPC site.

This section is meant to be a further expansion and refi nement of the Measure B Bond Program Design Standards Manual and the Measure B Bond Program District Design Guidelines, as those documents are district wide, these guidelines have been created for the LPC specifi cally.

DESIGN GUIDELINES- Conform to geo-technical reports for the project site

- Conform to no less than Chabot-Las Positas Measure B Bond Program District Design Guidelines (DDG), Design Standards Manual (DSM), and CADD Standards Manual.

- All projects must include as-built drawings in AutoCAD, pro-vided to the district upon project closeout.

9.2 Paving

Conform to geo-technical reports and no less than Chabot-Las Positas DDG and DSM for paving and related site work. Designers should consider the layout and dimensions of paving adjacent to planting areas in regard to minimizing potential irrigation over-spray due to the limitations of recycled water. The relationship between the dimensions of paving and planting areas should also be considered for maintenance reasons. The Las Positas cam-pus is know for its cleanliness, especially for such a small grounds staff, due in large part to the use of automated equipment, “…it is done successfully is with power equipment, blowers, sweepers, and vacuum trucks, not with rakes and brooms. Walkways need to be accessible to truck mounted equipment. Shrub beds need to be designed so that debris can be easily blown out of it (refer to Appendix: Sustainable Landscapes At LPC).”

Stepstone truncated domes

DESIGN GUIDELINES- Adhere to DSM DCS 005 and DCS 007 and DDG 004.

- If non-expansive fi ll is required under paving, consider im-porting asphaltic concrete grindings or recycled concrete or recycled aggregate base if it meets the specifi cations for non-expansive fi ll and is not hazardous.

- Evaluate use of permeable paving with geotechincal engi-neer to develop solutions for stormwater management and pavement use.

- Include a turned down edge at edges of paving to limit water infi ltration from adjacent landscape areas under paving.

- Exterior pedestrian concrete paving shall be 3000 psi with steel reinforcement (consider #4 rebar @ 18” on center), expansion joints where necessary and appropriate, saw cut joints where necessary and appropriate.

- Joint pattern to respect built forms.

- Final control joint design should be reviewed and approved by structural engineer.

- Topping slabs on structural concrete require design by struc-tural engineer.

- Concrete for vehicular paving per geo-technical report.

- Concrete for emergency vehicular paving per geo-technical report.

- Asphaltic concrete for vehicular paving per geo-technical report.

- Asphaltic concrete for emergency vehicular paving per geo-technical report.

- Asphaltic concrete paving must have a wood header with a moisture barrier or a concrete header.

- Use Stepstone concrete unit pavers where appropriate, match sub-base for concrete. Install per geotechnical recommenda-tions, not recommended for vehicular or emergency areas.

- Use asphalt pavers where appropriate, match asphaltic con-crete sub-base criteria per geotechnical recommendations. - Match asphaltic concrete sub-base criteria for decomposed granite sub-base.

- Due to expansive quality of native soils include non-expansive fi ll under paving per geo-technical report (see above note).



Relationship between paving and planting areas. Score joints refl ecting form of concrete paving and architecture.

Score joints refl ecting form of concrete paving (circular). Decomposed granite.

- Include concrete mow bands under fences adjacent to grass areas to minimize the need to maintain grasses at the fence line.

- Include an 18” wide concrete band at the exterior base of buildings where the building meets soil and planting areas. This band will serve to keep moisture away from the founda-tion, keep irrigation and shrubs off the building walls and allow access to the walls and windows of the building for mainte-nance.

- Use resin-based decomposed granite paving for decomposed granite paving near buildings (such as “Natural Pave”).

- Use decomposed granite paving without resin for rustic walk-ing trails.

- The DSM encourages the use of permeable paving. The tech-nical implementation of permeable paving for vehicular areas

may be limited due to the impermeable nature of compacted aggregate base courses required to support vehicular loads.Permeable pavers may be more feasible in pedestrian and light traffi c (maintenance vehicles only) areas. In all areas, designers need to understand risks involved with use of permeable paving when designing permeable paving and that water will go somewhere and the clay soils of the col-lege by nature have a limited capacity to absorb water and transmit it to the ground.

ADA REQUIREMENTSAs a minimum ADA requirements must be met, of course. There are some specifi c products that are required to meet ADA require-ments such as truncated domes.

DESIGN GUIDELINES

- Provide truncated domes where required.

- Truncated domes to be inline Stepstone (or approved equal) with yellow color or contrasting color.

9.3 PlantingTurf is easier to maintain at LPC than under normal circumstances given that it is easy to remove garbage from (compared to shrub beds) and there is no need to fertilize, because of recycled water use. “The key to low maintenance is to design the turf for our com-mercial equipment. Small lawns with ill-placed obstacles, like signs, light posts, trees, etc., are what makes [sic] turf diffi cult to maintain (refer to Appendix: Sustainable Landscapes At LPC).”

Designers should also consider the layout and dimensions of plant-ing areas in regard to minimizing potential irrigation overspray due to the limitations of recycled water. The relationship between the dimensions of paving and planting areas should also be consid-ered for maintenance reasons. The Las Positas campus is know for its cleanliness, especially for such a small grounds staff, due in large part to the use of automated equipment, “…it is done successfully is with power equipment, blowers, sweepers, and vacuum trucks, not with rakes and brooms. Walkways need to be accessible to truck mounted equipment. Shrub beds need to be designed so that debris can be easily blown out of it [sic](refer to Appendix: Sustainable Landscapes At LPC).” Over-spray is a signifi cant problem with recycled water due to inspections, environmental health, etc. Designers should be aware of over-spray issues when designing planting areas, curved lines are problematic – minimize curves, and be aware of head spacing.

DESIGN GUIDELINES

- Adhere to DDG 004 and DSM DCS007.



Turf panels with sand channel drainage. Palm tree selection at nursery.

- Respect existing planting where possible. Include specifi ca-tions for protection of existing trees and shrubs.

- Provide soils report for planting projects, including agricultural suitability and recommendations for planning soil amend-ment.

- Amend on site topsoil per soil report recommendation and provide import topsoil as required for specialty planting.

- Strip on-site topsoil, stockpile, protect and reuse for planting per soil report recommendations.

- Adjacent to paved areas provide adequate soil conditions for tree growth to full maturity.

- Include an 18” wide concrete band at the exterior base of buildings where the building meets soil and planting areas. This band will serve to keep moisture away from the founda-tion, keep irrigation and shrubs off the building walls and allow access to the walls and windows of the building for mainte-nance.

- Planting areas are required to self-drain and preferably have sub-surface drainage.



- Plant trees at least 15’ away from light poles.

- Plant trees at least 10’ away from the centerline of underground utilities and increase distance in response to pipe size. Refer to utility plan (Figure 8).

- Avoid placing trees under overhead utilities.

- Palms, if planted, require sub-surface drainage, sand backfi ll, and seasonal planting limitations.

- Palms, if planted, may require selection at nursery by Land-scape Architect or palm tree specialist.

- Plant material adjacent to buildings should be low water using and drip irrigated to protect building foundations and adjacent soil from the effects of water.

- Use deeply rooted plant materials on slopes for erosion control and drought tolerance.

- Provide appropriate bioswale planting (bioswale plantings can range from annually mowed “wild” plantings to regularly mowed turf with adequate drainage).

- Slow growing trees are preferred to large fast growing trees. Maintenance becomes a major issue. Can mix slow growing with fast growing trees.

- Plant selection should take into consideration the effect of recycled water on plants.

- Take into consideration, when selecting native plants, the concern that some native plant species will cross pollinate with Livermore area endemic plants thus compromising the endemic plant’s genetic integrity.

- Choose plants that are not considered hosts of Glassy Winged Sharpshooter, because of the detrimental effects to the wine industry.

- Require a 12-month maintenance period for planting and irrigation projects.

- As part of specifi cations, require an 11-month review for plant-ing and irrigation projects.

- Except at asphaltic concrete paving, use Trex (or approved equal) header in lieu of redwood or pressure treated wood headers where headers are needed.

-Generally separate mowed lawns from shrub and ground cov-er areas with wood or steel headers or concrete mow bands.



9.4 Stairs and Ramps

DESIGN GUIDELINES

- Projects will meet ADA criteria.

- Projects will meet criteria for Path of Travel.

- Projects will meet CBC criteria.

- Project specifi c stair noses will meet all applicable codes.

- Wide steps are acceptable where appropriate; like in an amphitheater.

- All stairs should follow a riser to tread ratio of 2:1 with a total of approximately 26.”

- Handrails to conform to material and fi nish of design guide-lines.

9.5 IrrigationBecause of restrictions on reclaimed water application, there is a very limited watering schedule. Requirements for recycled water call for watering only when there are no people on campus in addition, no standing water on paving is allowed, and no wet playfi elds are allowed during school hours. Because of early and late classes the realistic watering schedule is roughly 11:15 PM – 5 AM; this is quite a limited timeframe considering the amount of watering that needs to be done. In order to ease pressure on these time requirements, irrigation design should aim for stations that use 2” valves (higher fl ow rates), currently there are too many existing 1” valves existing on campus. On slopes, one method used to encourage water percolation, is to increase the frequency of watering while decreasing the time a valve is on. One important step to increasing the capacity for irrigation and easing the water schedule would be to upsize or manifold the irrigation water me-ter, the existing 4” line with 3” meter is an inadequate volume for campus irrigation. Irrigation water pressure is reported to be 90 psi at the top of campus. Carducci fi eld testing found 70 psi at bottom of campus and 30 psi at top of campus, which could be under irregular fi eld conditions. Designers should investigate pressure to determine accurate fi eld conditions. Over-spray is a signifi cant problem with recycled water, inspections, etc. Designers should be aware of over-spray issues when designing planting areas, curved lines are problematic – minimize curves, and be aware of head spacing. See Figure 9 for existing irrigation diagram.

- Valve fl ood bubblers separately from spray irrigation.

- Valve lawn areas separately from other irrigation.

- Complete native plant and like-native zones should be on isolated valves so they can be shut off after establishment. Coordinate remote control valves with hydrozones of planting design.

- In sloped areas valve circuits to refl ect the difference in water needs for the bottom, intermediate, and top of slope.

- In large turf areas, where appropriate, use gear driven rotors such as Hunter I-40 rotor (or equal).

- Use subsurface irrigation in planting areas adjacent to build-ings.

- Provide subsurface irrigation equipment with in-line emitters such as Toro DL 2000 or equal.

- Include a “Y” fi lter with remote control valves on subsurface irrigation systems.

- Hold dripperlines 18” off of face of building, 6” off of paving.

- Space dripperlines equally within each zone, 18” on-center maximum.

- Install air vacuum release valve(AVRV)(s) at high point(s) of each subsurface irrigation area. AVRV’s are shown to indicate intent- locate as required based on actual grades of the site. Locate one AVRV per 500’ of dripperline tubing.

- Possibly consider an Evaporative Control System (ECS) for subsurface lawn irrigation due to recycled water limitations and its storm water retention capabilities.

DESIGN GUIDELINES

- Meet ADA and Path of Travel criteria.

- Meet CBC criteria.

- Follow Best Management Practices.

- Drain surface runoff from vehicular paving into bioswales and biobasins. Incorporate stormwater detention in drainage systems. (See Figure 10)

- Slope bioswales and detention basins slope 1%-2% and in-clude subsurface drainage.

- There should be no residual standing water for more than 48 hours in bioswales, in order to prevent mosquito larvae.

- Use slotted curbs to conduct water into bio-swales in parking area.

Notes: (a) 33% is approximately the maximum slope for mowing machinery. (b) Slopes covered only by shrubbery tend to erode above 10%. Slopes over 6%

should have erosion protection. (c) The design intent is for the swales to appear natural and not man-make except

where it is desirable to have steeper side slopes to limit vehicles’ off-road access. (d) 1.5% minimizes wet soil conditions. Less than 1.5% requires subsurface drainage

and should be treated as a bioswale. (e) Slope is less then maximum allowed by code(8.33%) to allow for construction

tolerances and achieve CBC/ADA requirements. (f) Requires subsurface drainage.

- Avoid rainwater leaders/roof drains daylighting directly onto walks, paving, or drainage inlets. Water should go into storm drains planting areas or bioswaless/biobasins, while implement-ing necessary erosion control.

- Provide back drains in fi ll slopes per geo-technical report.

- Use at least 3000 psi concrete for concrete retaining walls.

- Use gray Keystone segmented retaining walls (or approved equal).

- Planting areas should self drain and possibly also have sub-surface drainage.

- Design a barrier free access route with the following:- Less than 1:20 slope without a ramp- Less than 1:50 cross slope- No abrupt changes in level- 48” min clear in width- Accessible path shall have no abrupt vertical changes exceeding 1/2” at 1:2 maximum slope, except that level changes do not exceed ¼”- Gate and door landings in accessible path of travel shall meet maneuvering clearances at gates per CBC Sections 1133b.2.4.2 & 1133b.2.4.3.- Contractor to verify that barriers in the path of travel in the areas work have been removed or will be removed in the project, and that the path of travel complies with CBC 1133b.

- Refer to chart for minimum, maximum and preferred slopes.

Section 10.0 - Conclusion


SECTION 10.0 CONCLUSION

Through review of Chabot-Las Positas Community College Dis-trict planning documents for future development, including the Facilities Development Plan, along with vital input form the LPC landscape committee, the Design Guidelines herein incorporate environmental protection and campus planning considerations for future development on-site together with site and landscape design parameters.

New development at the college is anticipated which may include a new student services entry building, outdoor amphi-theater and performing arts center, additional classrooms, and most certainly, the development of a primary pedestrian corridor known as the Boulevard. While this document does not specifi -cally propose new development or authorize any new construc-tion, it does provide recommendations for project proposals for-mulated in the future. Its purpose is to defi ne design parameters regarding, landscape and site architecture, lighting, signage, and environmental protection.

Detailed environmental review and additional studies will be required for any proposed future projects. However, these guide-lines outline ways to reduce adverse environmental effects and provide a framework for the future development of high-quality projects, which will promote a strong campus experience. The County is committed to the enhancement of the Civic Center campus and to ensuring the protection of its natural resources and community assets.
