Site Master Plan Recommendations

Site Master Plan Recommendations

Site Priorities

The priority list was developed by integrating PTA, Staff, and consultant concerns gathered from meetings. 
At the second staff meeting the design team reviewed each item with the staff. Items shown in green text are items that must be completed with any work done on site. The items shown in red are items that can be moved up or down on the priority list based on site votes. The staff members received three votes to place next to their preferred objectives. The accumulation of votes led to the overall site priorities.

Below is a general description of the three categories for prioritization:

01. CODE COMPLIANCE will have to be satisfied when any work is done on site. This includes adequate bathrooms, adequate ventilation, and California energy efficiency requirements. None of these items were votable as they are all mandatory.

02. FUNCTION is the next priority category andincludes items that support the physical site and building. This includes adequate building systems such as lighting and mechanical, and appropriate low voltage and daylighting. Only basic upgrades are mandatory, other items were shown in red and can move up or down their priority category based on site votes.

03. EDUCATION SUITABILITY is the final priority category and the one most sites focused on. This category focuses on what a site and a building need to support the education curriculum. It includes items such as a fully functional science lab, a staff collaboration space, and storage rooms to remove clutter from the classrooms.

Marin Elementary School Site Recommendations

ARCHITECTURAL

Site

The play area is to be enlarged and upgraded in all options. Currently the pod buildings make reorganizing play space difficult, as they exist in a cluster in the middle of the site. Therefore, in Option 1 where most of those buildings remain, site enlargement can be done but not as efficiently as starting from scratch.

Option 1

The play area is enlarged by removing portables. Some additional outdoor spaces can be an outdoor covered lunch area, an outdoor stage, or an outdoor classroom.

Option 2

This option more than doubles the useable play area on site. Possibilities include recreating the site garden, integrating softscape, an outdoor classroom, etc.

 

Building A – Kindergarten

Option 1

This building remains on site and is modernized to a like-new condition. The kindergarten classrooms are to be renovated to include the code requirements for kindergarten, i.e., access to kinder restrooms from every classroom. Directly adjacent to this building should be a play area for kindergarten children with age appropriate play equipment and surfaces.

Some walls between rooms are lacking in acoustical insulation. Site users report distracting sound penetration between spaces. Appropriate acoustic treatment should be placed in or on the walls separating classrooms.

Option 2

Demo the building in its entirety.

 

Building B – Administration

Option 1

This building remains on site and is modernized to a like-new condition. The current configuration of offices may not be adequate for the current or future administration. An adjacency study should be completed to determine if spaces should be moved or enlarged. The existing condition lacks specialist offices (counselor, psychologist, etc.) as well as a staff workroom. These are necessary components for the site and need to be included in any future reconfiguration, either in this building or in the nearby new building.

The classroom in this pod can be moved to the new building on site, thus allowing more space to be devoted to administration in a single building. Options for this space include a staff workroom which is currently sharing a space with the staff lounge.

Some walls between rooms are lacking in acoustical insulation. Site users report distracting sound penetration between spaces. Appropriate acoustic treatment should be placed in or on the walls separating offices.

Option 2

Demo the building in its entirety.

 

Building C – Multi-Purpose

All Options:

Enlarging and replacing the Multi-Purpose Building is a high priority for both staff and parents. Currently the building does not serve the needs of the site and significant alterations would have to be made to make it useful. Therefore this building in both scenarios should be demolished and rebuilt according to state standards and/or site needs. The new multi-purpose room will be enlarged and will provide a stage / performance space. It is to have a strong public presence and be accessible by the public, especially after hours for PTA meetings and community events. However, access to the space should be supervisable.

 

Building D, F, and G - Classrooms

Option 1

This building remains on site and is modernized to a like-new condition. Classrooms are to be upgraded with the technology standards of the District. Finishes are to be upgraded. Built-in storage should be assessed and either replaced or refurbished.

Some walls between rooms are lacking in acoustical insulation. Site users report distracting sound penetration between spaces. Appropriate acoustic treatment should be placed in or on the walls separating classrooms.

Option 2

Demo the building in its entirety

 

Building E – Library /Media Center

Option 1

Enlarging the Library is another high site priority. The existing Library is undersized for the site. This can be accomplished by demolishing a wall that was added adjacent to the Library to create an instruction space. Doing this would remove the instruction space from this building and it would have to be replaced in the new building. The Library/Media Center is to conform to District technology standards. Upgrade finishes and bring the building to a like-new condition.
The classroom in this building is to be modernized as well, following the Building D recommendation.


Option 2

Demo the building in its entirety.

 

 Building H – Classrooms – Original Building

Option 1

This building is from the original construction of the school. Although systems need to be upgraded, the overall size, shape, and usefulness of this building is appropriate for Option 1.

Option 2

Demo the building in its entirety.

 

Building I , J, K– Classroom – Portable

All Options

Portable building – remove from site. Consult with District for new location. It may be used for temporary housing on another site.

 

Building L and M – Classrooms – Modular Building

All Options

The top priorities on this site state a need to increase the play yard space and to increase the size of the Multi-Purpose Room. Currently, the location of this building restricts the space needed to accommodate these priorities. Also, since this building is a modular building, modernizing it to a like-new condition is not the best investment of District funds. It is recommended that this building be demolished and salvageable components are stored and/or relocated by the District.

 

New Building

Option 1

The new building in Option 1 consists of a single-story Multi-Purpose Building and a two-story classroom wing. Most of the pod buildings remain, as well as Building H, the original building on site. The portables and modular buildings have been removed from the site to make room for the new building and open up play area.

    1. The Multi-Purpose Building should serve as a dining facility, assembly, and performance space. It should include adequate facilities for a kitchen, staff lounge, and after school program.
    2. The two-story classroom wing should fulfill the technology and curriculum plan of the District.

Option 2

The new buildings will be two-story to accommodate the school population on this small site. Providing an all new two?story facility will more than double the amount of useable outdoor play space – a high priority for the site committees.

There should be three main building components:

    1. The two-story classroom wing should fulfill the technology and curriculum plan of the District.
    2. Two-story administration, media center, and classroom wing. Administration and media center are to be located on the first floor for easy public access and classrooms on the second floor.
    3. Single-story Multi-Purpose Building. The Multi-Purpose Building should serve as a dining facility, assembly, and performance space. It should include adequate facilities for a kitchen, staff lounge, and after school program.

 

 

CIVIL

Code Compliance and Safety

It is assumed that both of the options presented would trigger a DSA review of the site accessibility and emergency vehicle access. Because the ramp along Santa Fe is in compliance, it is recommended it remain in place for either option. Each option is discussed below in terms of civil engineering.

 

Option 1

This option would involve adding a new classroom at the corner of Santa Fe and Marin. This building and surrounding paving surfaces would be subject to C.3 stormwater quality requirements.

A new private fire main would be required to provide a fire hydrant and sprinkler service for the new building. Because the existing site grades make it impossible for emergency vehicles to access the interior of the campus, this fire service would need to be accessible from the street frontage.

ADA access on the rest of the campus would need to be improved according to the site assessment, including areas between Buildings A and B.

 

Option 2

Option 2 is a complete reconstruction of the campus. All new impervious surfaces created or replaced by the project would be subject to C.3 stormwater requirements. The site topography would facilitate treatment of stormwater in bioretention areas.

All of the new buildings would have fire sprinklers served by a new fire service. Each building would have a fire department connection (FDC) that would be accessible by firefighters from the street frontage.

The new site would have a designated path of travel to each building per DSA requirements. As mentioned above, the existing ramp on Santa Fe would remain in place to serve the new campus.

 

 

LANDSCAPE

The following landscape improvements are recommended:

Selective improvements to perimeter planting and at renovated or new buildings.

Campus perimeter planting improvements are to replace overgrown and poorly spaced or sheared plantings.

Bio?filtration planting shall be incorporated where possible to treat campus and roof runoff.

Where seating is provided, it shall be configured to encourage interaction between students and create opportunities for collaboration and functional use of outdoor areas as an extension of the classroom.

Play structures shall be low maintenance, long life span structures that accommodate large numbers of children in an inclusive manner. Play elements will be age appropriate and provide a variety of physical development options. Underlying safety surfacing shall be designed to meet or exceed fall height of the structures. Play areas shall be designed to ASTM, CPSC, and ADA requirements. Play areas should be installed by or verified after installation by a certified playground safety inspector. We recommend structures such as those built by Corocord, Dynamo Play, and Elephant Play for their creative designs, high play value within a small footprint, ADA accessible designs, and durability. We recommend the use of non-infill synthetic play turf with underlying shock pads in place of pour-in-place rubber due to lower installation and maintenance costs and because it is a more versatile, attractive surface material.

Where blacktop is striped for games, the striping shall be laid out to avoid overlaps in use that could lead to playground injuries.

Typically, landscape improvements shall comply with DSA and California Building Code requirements, including CALGreen, District directives, and Title 23 Irrigation Efficiency requirements.

Paved areas shall be designed for universal access.

Concrete paving shall utilize a mix of fly ash and slag replacing approximately 50% of Portland cement in order to reduce greenhouse gas emissions, provide a significant level of recycled material content in the paving, and increase the strength of the finished paving, thereby increasing its durability and lifespan. Concrete shall be non-slip broom or soda wash finish, in order to reduce install cost and construction clean up, and will not have lamp black added, to ensure that the paving remains high-albedo and reduce the urban heat island effect over the long-term.

Where appropriate, asphalt paving shall be color coated with high-albedo, slip resistant surface treatments to provide visual interest and reduce urban heat island effect while maintaining usefully large, contiguous paved areas.

Plantings shall be climate appropriate, low water use native and adapted non-invasive exotic plants. Where possible, mowed lawn should be replaced with native, non-mowed meadow, significantly reducing irrigation and maintenance.

Irrigation systems shall be weather aware, automatically adjusted to reduce waste, and meet or exceed state and local irrigation efficiency requirements.

We recommend that although not required, the nine Bay-Friendly Landscape basic practices be followed in order to further reduce irrigation use and maintenance costs, and to protect the local environment. Landscape maintenance staff should be trained in Bay-Friendly Landscape practices. District maintenance practices should incorporate Bay?Friendly Landscape practices which reduce water use, strive to eliminate pesticide and chemical fertilizer use, and tend to reduce landscape maintenance costs. The nine Bay-Friendly practices are:

  1. All soil on site is protected with a minimum of 3 inches of mulch after construction.
  2. Compost is specified as the soil amendment at the rate indicated by a soil analysis to bring the soil organic matter content to a minimum of 3.5% by dry weight or 1-2 inches of compost. If the imported or site soil meets the organic content of 3.5% or more, then the requirement is waived.
  3. Divert 50% of landscape construction and demolition waste by weight. Verify the local jurisdiction’s minimum requirement and reporting procedures for construction and demolition (C&D).
  4. Select and plant vegetation to allow for natural size and shape growth. Pruning for structural integrity and overall health is permissible. Plants adjacent to buildings or established in a row should allow for their minimum and maximum growth potential, according to a reference plant book.
  5. Do not plant invasive plant species.
  6. Grow drought tolerant California native, Mediterranean or climate adapted plants.
  7. A maximum of 25% of total irrigated area is specified as turf, with sports or multiple use fields exempted.
  8. Specify water-based irrigation controllers (automatic, self-adjusting) that includes a moisture and/or rain sensor shutoff.
  9. Sprinkler and spray heads are not specified for areas less than 8 feet wide.

 

Option 1

An outdoor classroom at the existing tree grove at the corner of Marin and Curtis.

Picnic seating adjacent to the new lunch shelter area accommodating alternative seating options and creating space for student collaboration.
Preserve the existing farm garden and improve accessibility to it.

Campus perimeter planting improvements to replace overgrown and poorly spaced or sheared plantings. Bio-filtration planting shall be incorporated where possible to treat campus and roof runoff.

“Learning Curve” seat walls are proposed to accommodate outdoor classroom space, with shade trees and native meadows.

 

Option 2

An outdoor classroom at the existing tree grove at the corner of Marin and Curtis.

Boulder seating in an adjacent landscape meadow as an extension of the new lunch shelter area, accommodating alternative seating options and creating space for student collaboration.

A planted buffer between the kindergarten play yard and the adjacent campus blacktop.

A new kindergarten yard including a play structure, trike track, garden area, and outdoor classroom.
Selective improvements to perimeter planting and at renovated or new buildings.

Campus perimeter planting improvements to replace overgrown and poorly spaced or sheared plantings. Bio-filtration planting shall be incorporated where possible to treat campus and roof runoff.

A larger farm garden consisting of raised planting beds, accessible permeable pathways, food harvest areas / curriculum gathering hubs, compost bins, worm composting stations, and cold frame or greenhouse structures to accommodate winter season gardening.

 

 

STRUCTURAL

Option 1

The existing buildings would be retrofitted, with the retrofit program primarily consisting of reinforcing the wall to roof connection at each building. The connections would generally consist of a Simpson “holdown” type bracket bolted to the wood framing and masonry walls at a regular spacing around the perimeter of the buildings. In addition, certain existing plywood shear walls would be reinforced through the addition of plywood or foundation bolts and certain roof collector connections would be reinforced.

The new building could be a wood framed structure with the roof consisting of plywood sheathing over prefabricated I-joists and glu-lam beams. Walls would be wood framed with lateral forces resisted by plywood shear walls. The ground floor would be a concrete slab on grade over conventional shallow foundations.

The existing retaining wall would receive minor repairs to fix localized spalled and cracked concrete.

Option 2

The new buildings could be either wood or steel framed structures. If the buildings are wood framed, the floors and roofs could consist of plywood sheathing over prefabricated I-joists and glu-lam beams. Walls would be wood framed with lateral forces resisted by plywood shear walls. If the building is steel framed, the floor and roof decks would consist of concrete topped metal decks supported by steel beams, girders, and columns. Lateral forces would be resisted by steel braced frames. The ground floor would be a concrete slab on grade over conventional shallow foundations.
The existing retaining wall would receive minor repairs to fix localized spalled and cracked concrete.
