2.0 FRAMEWORK

2.1 Arroyo Seco Master Plan

. The Arroyo Seco Master Plans include the following:

• Hahamongna Watershed Park Master Plan

• Central Arroyo Seco Master Plan

• Lower Arroyo Seco Master Plan

• Rose Bowl Use Plan

• Design Guidelines for the Arroyo Seco

2.2 Goals and Objectives of the Arroyo Seco Master Plan

These Design Guidelines are intended to provide guidance for implementation of the objectives set forth in the Arroyo Seco Master Plan and other applicable directives such as the Arroyo Seco Lands Ordinance, pertinent traffic management plans, multigovernment agreements, and other appropriate standards.

I-3

3.0 IMPLEMENTATION PROCESS

3.1 Park Improvements and Capital Improvement Projects

All projects shall be subject to the requirements for design review pursuant to the Pasadena Municipal Code. Park improvements shall be subject to the City’s Capital Improvements Projects (CIP) review process. As such, the Parks and Natural Resources Division Administrator (under the Department of Public Works) shall find that the major improvements and/or CIP project is in substantial conformance with the Arroyo Seco Design Guidelines and will initiate reviews by the City’s Design Commission, Recreation and Parks Commission, and the Historic Preservation Commission (if appropriate).

Reference to commission review in specific sections of these guidelines does not imply that commission review is unnecessary with respect to other areas.

3.2 Minor Park Improvements

All projects shall be subject to the requirements for design review pursuant to the Pasadena Municipal Code. Minor park improvement activities will be subject to a substantial conformance review by the Parks and Natural Resources Administrator and the Planning and Development Director for compliance with the Arroyo Seco Design Guidelines. These minor improvements include repair of existing structures and replacement of plant materials.

4.0 AMENDMENT PROCESS

Amendments to the Arroyo Seco Design

Guidelines shall be reviewed by the Design Commission, the Recreation and Parks Commission, and the Historic Preservation Commission (if appropriate), and then submitted to the City Council for approval.

CHAPTER 1

OVER-RIDING DESIGN

PRINCIPLES

1.1 OVERVIEW

These Design Guidelines seek to ensure an ongoing effort to preserve the unique character of the Arroyo Seco by providing a unifying set of design principles for the three sub-areas that make up Pasadena’s Arroyo Seco. The commonalities between the three sub-areas are the backbone of these design guidelines.

Factors to be considered are:

• Restoration of the Arroyo Seco Stream

Course and Environment;

• Habitat Restoration;

• Preservation of Cultural Resources;

• Enhancement of Appropriate Recreational

Opportunities;

• Limitation of Man-made Objects in the

Natural Environment;

• Flood Management in Balance with the

Natural Environment;

• The Challenge of Integrating and Regulating

Private Use within the Arroyo Seco;

• Water Conservation and Protection of Water

Resources, and

• Public Safety and Accessibility

Each of the three sub-areas also have the following unique elements which contribute to the formulation of the design principles.

1.2 Hahamongna Watershed Park

• As the largest undeveloped, though altered, wild area in the City of Pasadena, and the gateway to the wilderness area of the National Forest to the north, its character should minimize man-made modifications.

Any improvements should be done to

1-2 minimize their impact and dominance over any native plants or animals.

• The proximity to the San Gabriel Mountain range mandates close attention to flood and sediment management for the safety of downstream uses;

The rehabilitated Devils Gate Dam provides opportunities for the seasonal holding of water for water conservation and habitat restoration; and

• The area provides 40% of Pasadena’s water supply.

1.3 Central Arroyo Seco

• The Rose Bowl is set in the midst of a natural preservation area and residential neighborhoods;

• This sub-area has:

• The most developed park land and the greatest active recreational use;

• The largest amount of paved parking;

• The greatest amount of turf with the existence of Brookside Golf Course; and

• Culturally significant structures, walls, and trails that need preservation.

• Attention must be paid to traffic mitigation including public transportation.

1.4 Lower Arroyo Seco

• This area has been designated a cultural heritage landmark;

• This sub-area has:

• The most confined area for competing recreational uses;

• Culturally significant structures and walls that need preservation;

• An experimental low-flow stream restoration project; and

Residential neighborhoods in close proximity to natural preservation areas

1-3

1.5 General Guiding Principles for Design Guidelines

The chapters that follow set forth numerous guidelines to ensure a desirable result for future improvements in the Arroyo Seco. The following general guiding principles are at the core of each of the specific guidelines developed for the Arroyo Seco and its environment:

• Limit the creation of man-made objects and minimize any impact to the natural environment.

• Enrich and promote the unique natural character of the Arroyo Seco;

• Restore the Arroyo Seco stream course and its environment;

• Encourage simplicity of design and integrity of materials;

• Provide a safe and secure environment for people and animals within the limits of the natural environment;

Figure 1-2 La Casita in the Lower Arroyo embodies many of the general guiding principles.

1-4

• Avoid use of colors that distract from the natural environment;

• Use appropriate scale to ensure harmony with surroundings and the human scale;

• Use natural materials;

• Provide accessibility for all where possible;

• Preserve natural resources;

• Ensure that improvements can be maintained; and

• Preserve historical and cultural elements.

CHAPTER 2

HABITAT RESTORATION AND

LANDSCAPE IMPROVEMENTS

Consistent with the Arroyo Seco Ordinance and the Arroyo Seco Master Plans, new plantings within the Arroyo Seco shall be native species when practical. There are also unique settings which include long-established gardens and high-use recreation areas. This chapter seeks to clarify these distinctions and provide criteria to assist with the implementation of habitat restoration and ongoing park landscaping improvements which preserve the unique character of the Arroyo Seco.

This chapter is organized as follows:

2.1 HABITAT RESTORATION

2-2

2.1 HABITAT RESTORATION

The conservation and restoration of open space areas within the Arroyo Seco is the cornerstone of creating a cohesive park and one that embodies the natural heritage of this important watershed. Only if the natural areas are carefully restored and conserved in perpetuity, will the true potential for this park be realized. The Arroyo Seco can become an ecological living laboratory and a respite for Pasadena residents as well as a testimony to their commitment to ecological preservation.

2.1.1 Definition

Habitat restoration plans or projects for the Arroyo Seco Master Plan will:

1. Preserve the historical ecosystem of the Arroyo;

2. Reestablish, enhance, and manage the plant communities native to the

Arroyo Seco Region of the San Gabriel foothills;

3. Protect and enhance the Arroyo Seco Watershed;

4. Allow public access to the natural habitats and open space consistent with the goal of protecting the habitat by considering the carrying capacity;

5. Enhance the habitat for greater biodiversity;

6. Create and/or maintain continuous transitions of natural habitat as a wildlife corridor that connects Pasadena’s Arroyo Seco to the larger Arroyo Seco Watershed and the San Gabriel foothills; and

7. Provide for the maintenance, monitoring, and assessment of the plan andd its projects with special consideration for additional plantings.

Figure 2-3 Changes in habitat from summer to winter in the Hahamongna Watershed Park.

2-3

2.1.2 General Guidelines

1. All habitat restoration plans will comply with the special regulations for natural preservation areas from Pasadena City Ordinance, Chapter 3.32, Arroyo Seco Public Lands, or its amendment.

2. Native plant communities will be established in areas that previously supported their ecology but have become altered.

3. Habitat restoration will maintain local genetic diversity.

4. Habitat restoration plan criteria:

a. All restoration plans shall have the benefit of specialty consultants to ensure viability of restoration efforts;

b. Restoration efforts will promote better quality habitat for wildlife;

c. Seed and other planting material (e.g., cuttings and container stock) will be collected from the project vicinity to the extent feasible, and/or, if necessary, will utilize plant stock material from reputable native plant nurseries;

d. Site preparation and planting techniques for all restoration efforts will comply with the Biological Technical Report for the Hahamongna Watershed Park and the Plant Palettes found in Appendix A;

e. Responsibility for maintenance of planting and for the monitoring of their progress is required;

f. Habitat restoration plans will eliminate ruderal areas within the Arroyo Seco as much as possible due to their low habitat value for wildlife and native plant species;

g. Seasonal timing (late fall, winter, and early spring rainy seasons) for planting will be anticipated to attain a successful restoration planting.

Figure 2-4 Opportunities for riparian habitat restoration and/or enhancement are prevalent throughout the Arroyo Seco

2-4

5. Restoration Plan projects shall be designed to restore the natural plant communities for improved habitat quality for biodiversity (flora and fauna), sustainability, landscape aesthetics, and the concomitant enjoyment by park users.

6. Any habitat restoration site that requires grading will apply landform-contouring principles found in Appendix C.

7. Any habitat restoration should strive to remove nonhistoric structures and return original grades where feasible.

Figure 2-5 Use of City-produced mulch is a valuable tool for successful habitat restoration projects.

2.2 LANDSCAPE IMPROVEMENTS

2.2.1 Definition

Landscape improvement areas are those areas that are not identified as habitat restoration areas but where planting is desired. Landscape improvement areas typically include areas around buildings, natural open space areas, grass areas not used as sports fields, roadways, specialty gardens, and planned beautification areas.

2.2.2 General Guidelines

1. Landscape improvements will preserve the historical heritage of the City of Pasadena and the Arroyo Seco.

2. Landscape improvements will preserve and protect the natural resources within the Arroyo Seco.

3. Landscape plantings in any area that is not a habitat restoration area or natural open space shall:

a. Utilize species from plant communities native to the Arroyo Seco

Watershed (see Appendix A);

b. Use California native plants;

c. Use drought-tolerant, water- conserving species;

d. Keep use of nonnative species to a minimum and only specify when native species will not be in the best interest of the landscape improvement due to the need to blend with an existing adjoining landscape, maintenance constraints, environmental site conditions (soil, exposure, micro-climate, etc.) and/or desired aesthetics; and

e. Any nonnative plants shall be selected so as not to pose a threat of excessive proliferation or threat to native species.

4. Multipurpose fields and open play areas within the Arroyo Figure 2-6 Drainage solutions within park area shall utilize naturalized design solutions.

2-6

Seco will use turf as the predominate plant material; however, the use of turf should be kept to the minimum extent needed.

5. Turf varieties that are water conserving, tolerant of heavy use, and not dependent on chemical fertilizers for their success are preferred.

6. Heavy-use or vehicular-access turf areas will be constructed using products that provide added structure and resist compaction.

7. The use of herbicides and pesticides will be discouraged.

8. Where required, custom-mixed N-P-K ratios of organic fertilizer (such as Ultra-gro) in combination with irrigation best management practices are preferred to ensure complete absorption and to avoid impacts on groundwater.

9. Mulching in open areas and within the drip line of new plantings is highly encouraged for weed control. Mulch shall be of the highest quality and free of weed seeds and invasive seedpods, free of palm fronds and pine needles, and free of chips from invasive plants (castor bean, arundo dona, and tree tobacco).

10. Responsibility for maintenance of planting and monitoring the progress of new planting areas is required.

11. Landscaping will be used to provide screening, as needed, between identified park-usage areas such as active recreation areas, structures, and parking lots. Landscape screening criteria include:

a. Choosing a plant palette indigenous to nearest open space area;

b. Grouping trees to simulate natural stands;

c. Planting canopy trees to unify an area choosing dominant tree type indigenous to the area;

d. Installing intermediate trees for screening, windbreak, and visual interest;

e. Planting shrubs as baffles and screens and to add visual interest with floral and foliage display; and

Figure 2-7 The landscape at La Casita is a fine example of native planting .

2-7

f. Installing ground cover to stabilize slopes and berms.

12. Vines should be permanently secured to vertical building/wall surfaces. At retaining walls, vines and shrubs shall be installed and spaced so as to completely cover walls at maturity.

13. Plantings should be arranged by similar moisture needs.

14. The arterial streets and collector roads within the Arroyo Seco shall be pedestrian oriented. Canopy shade trees are to be regularly spaced within beds of shrubs and/or groundcover. This treatment will also provide a canopy over the walkways for a more pleasant pedestrian environment. The use of similar understory plant materials will unite a landscape theme along a roadway.

15. Plantings of the slopes in the Arroyo Seco will be landscaped with:

a. Species from plant communities native to the Arroyo Seco Watershed

(see Appendix A); and/or

b. California native species.

16. The slopes of the Arroyo Seco shall serve and contribute to the wildlife corridor of the Arroyo Seco Watershed.

17. Slopes that serve as buffers between developed park areas and surrounding residential neighborhoods will be landscaped with taller tree species in natural groupings to mitigate any impacts caused by the developed park areas.

18. Tree placement on slopes adjacent to parking lots will be landscaped to mitigate any impacts caused by the parking lots.

19. Irrigation Systems shall not be exposed.

Figure 2-8 Native flowers highlight trail-hiking experience.

2-8

2.3 FIRE MITIGATION

2.3.1 Definition

The sloped areas are the steep banks of the Arroyo Seco, some of which are identified as natural preservation areas by the Arroyo Seco Public Lands Ordinance. These areas have unique landscape requirements.

Fire Mitigation is the management of the threat of fire and is of great importance in the Arroyo Seco landscape.

2.3.2 General Guidelines for Sloped Areas

1. Fire protection efforts will not jeopardize the stability of the slopes.

2. Fire protection considerations shall not take precedence over appropriate habitat restoration.

3. Slopes adjacent to the new and existing park areas as well as residential neighborhoods will receive special landscape treatment to mitigate the visual impact on the park areas. The slopes will be landscaped at a greater density than the average interior project slopes. The slopes will have an informal quality relating to a more naturalized character.

4. Tree placement on slopes adjacent to parking lots will receive exceptional efforts to mitigate the visual impact of the parking lots.

Figure 2-9 Slopes adjacent to developed park areas, and separating park areas from a residential neighborhood, will incorporate taller trees in natural groupings.

2-9

2.3.3 General Guidelines for Fire Mitigation

1. Fire mitigation shall be balanced with habitat conservation and slope protection.

2. Denuding of slopes shall be prohibited.

Figure 2-10 Brush clearing shall be balanced with habitat conservation and slope protection.

Chapter 3. Architecture

3-1

CHAPTER 3

ARCHITECTURE

Pasadena has played an important role in the evolution of its architecture. Architectural expression within and adjacent to the Arroyo Seco will continue to reflect this contribution and be an important part of the total effect of the park’s impact on the community. Each structure should seek to demonstrate the harmony between what is built by man and what exists naturally.

This chapter is organized as follows:

3.1 ARCHITECTURAL DESIGN CONCEPTS

3.1 ARCHITECTURAL DESIGN CONCEPTS

3.1.1 Definition

These guidelines provide the direction for all new construction, renovations, alterations, improvements and replacements to existing structures and event-related facilities within the Arroyo Seco.

3.1.2 General Guidelines

1. All structures shall be of a scale and character appropriate to the Arroyo Seco and their location shall be environmentally sensitive and integrated to the site.

2. All facilities shall emphasize the natural setting and use of natural materials.

3. Structures and facilities that are replacements to existing buildings/facilities shall contribute to and enhance the park environment as a whole without any loss or degradation of habitat or openspace. Any such buildings shall not significantly increase the floor area or height over the original structure.

4. Structures serving the same function (such as restrooms) shall use the same color palette throughout the Arroyo Seco. Building color shall not use more than three colors and should be warm and earth-toned. When appropriate, arroyo stone should be incorporated into the design.

5. Architecture shall provide visual and textural interest discernable through site-sensitive massing, quality building detailing, materials, and colors.

6. The siting and layout of the improvement shall consider the microclimate of the Arroyo Seco and modifications to the microclimate induced by the improvement. The microclimate produced by a building in relation to its

Figure 3-2 This demonstrates a before and after of an existing restroom facility with the earthen tones and stone design specification simulated.

3-3 immediate surroundings will impact users. Microclimate factors include sun, shade, glare, precipitation, surface and ground water, and wind and breezes.

Modifications to microclimate can be produced by landscaping, walls, grading, hardscape, water features, lighting, planting, irrigation, and other built or natural elements as well as the improvement itself.

9. The use of sustainable materials and sustainable design approaches is strongly encouraged.

3.1.3 Unique Settings

1. In the Central and Lower Arroyo Seco, new structures are currently restricted in the Natural Preservation Areas to those required for utility operations, park maintenance, and protection of plant and animal communities.

1. All changes to existing structures within the Lower Arroyo are subject to the

Historical Landmark review process.

Figure 3-3 La Casita del Arroyo, is a popular landmark in the Lower Arroyo Seco and represents many positive architectural elements.

3-4

3.2 PUBLIC USE STRUCTURES

3.2.1 Recreational/Clubhouse Facilities

1. All structures shall have colors sympathetic to the Arroyo Seco color palette.

(See 3.1.2 #4.)

2. All existing structures shall seek to incorporate ADA accessibility standards into improvement plans.

3.2.2 Restrooms

1. All bathroom structures will be of the same color palette. (See 3.1.2 #4.)

2. Design and layout of restrooms shall be easily accessible from picnic and primary activity areas. When adjacent to play areas, some consideration shall be given to providing limited sports equipment storage. Since the adoption of these guidelines, a storage policy was put into place; see Appendix F .

3. Restroom structures shall be accessible and comply with ADA requirements.

4. The use of doors and gates shall be avoided during hours of operation by locking them open.

5. Restroom structures shall be able to be secured when not in use.

6. In the upper and lower Arroyo Seco, sloped roofs with fire-retardant slate-colored shingles shall be used to prevent collection of leaves and trash. Gutters are not desirable.

7 Storage rooms for maintenance and recreational use storage should always be considered in the design to minimize the number of structures.

8. There shall be a landscape plan for every restroom.

3.2.3 Maintenance Facilities

Maintenance facilities include, but are not limited to, storage yards, maintenance field offices, and large bin-storage areas (Refer to Appendix F, Park Equipment Storage Facility Policy).

1. Maintenance facilities shall be located away from major areas of activity and from natural settings.

2. Maintenance facilities shall be accessible from an existing all-weather road.

3. Maintenance facilities shall be enclosed for safety. (Refer to Walls, Fencing, and Gates, Chapter 7)

4. Maintenance facilities shall provide an aesthetically designed enclosure or covered area to protect equipment and vehicles from the elements.

5. Maintenance facilities shall be located in as remote a location as possible and aesthetically designed and screened to minimize any visual impacts to the greater park area.

6. Site facilities shall be located or landscaped to provide tree canopy to minimize views from below and above.

3-6

3.2.4 Open Structures and Bridges

1. Wood and timber construction is preferred for overhead trellises.

2. Open structures shall use wood beams in combination with wood, concrete, brick, arroyo stone piers, unpainted weathering steel or other natural materials, i.e., copper and wrought iron.

3. Built-in grills, outdoor sinks, water fountains, and picnic tables shall be considered in the design and layout of picnic shelters.

(Refer to Site Furnishings, Section 11.7.)

3.2.5 Permanent Storage Facilities

1. All storage facilities in the Arroyo Seco shall comply with the City’s Park Equipment Storage Facility Policy, Appendix F.

3.2.6 Event-Related Facilities

1. Event-related facilities shall be defined as all those temporary structures and lights relating to the facilitation of temporary events including but not limited to fabric or fabric-like structures, tensile structures, inflatable structures, kiosks, directional devices (including temporary signs and way-finding signs), fencing, viewing stands, and corrals.

Figure 3-5 The trellis structure at La Casita in Lower Arroyo is a good example of heavy timber construction.
