SECTION I: FINDINGS

 

 

  1. WHEREAS Marin Horizon submitted a Use Permit and Design Review application to undertake programmatic changes and physical improvements to their facility. The project is a proposal to demolish an existing 5,900 square foot one-story classroom building and construct a new 11,478 square foot classroom building for a total building area of 24,451 square feet for the Marin Horizon School on the 2.27-acre Homestead School site. The new classroom building would be a primarily two-story building with a three-story component. The maximum height of the building, not including the mechanical enclosure would be 36.2 feet above grade. The maximum height of the mechanical enclosure would be 39.5 feet above grade. The following describes the various building heights and the respective area of each portion of the building and the mechanical equipment enclosure:

 

  • Approximately 2,480 square feet of the two-story portion of the building would have a 2:12 sloped roof with a maximum height of 32 feet above grade sloping down to 26 feet above grade.
  • Approximately 903 square feet of the three story portion of the building would have a nearly “flat” 0.375:12 sloped roof with a maximum height of 36.2 feet above grade.
  • Approximately 791 square feet of the building would have a “nearly flat” 0.375:12 sloped roof- covered deck with a maximum height of 26 feet above grade.
  • Approximately 341 square feet of the three-story portion of the building would be a mechanical equipment enclosure with a maximum height of 39.5 feet above grade.

 

The building would have the following minimum property line setbacks: 19.5 feet front (north); 15 feet side (west); 170 feet side (east); and 170 feet rear (south). The project also includes a proposal to increase the permitted number of students enrolled in the school by 50 students, from a maximum of 250 students to a maximum of 300 students; increase staff levels from 44 Full Time Staff Equivalent (FTE), comprised of 31 full time and 16 part time employees, to 49 FTE comprised of 44 full time and 10 part time staff; construct a new stepped terrace along the western side property line; construct 14 new parking spaces on the southern portion of the playground for a total of 49 parking spaces; construct a new transformer 11 feet from the front property line facing Montford Avenue; demolish 10 feet of building located adjacent to the driveway access on the south side of the property; construct an additional pedestrian emergency walkway from the third floor to Montford Avenue; remove two redwood trees, one Monterey pine tree, one strawberry tree, and one fir tree; and install new landscaping.

 

The project also includes an Encroachment Permit to allow existing diagonal striping for the passenger loading area along Melrose Avenue to extend 2 feet into the street right-of-way. The additional encroachment into the right of way is to provide for a wider pedestrian way between the school building and the passenger drop-off and pick-up area for safety reasons. No change to the length of the passenger loading area is proposed.

 

Land Use Changes

 

The proposed land use changes include modifications to the school’s 1993 Use Permit to: (1) increase the enrollment from 250 to 300 students, and to (2) increase the staff from 44 FTE to 49 FTE. No change to the number of special non-instructional events in the evening is proposed.

 

Table 1 outlines the proposed changes. (The proposed changes to the 1993 Use Permit are bolded.) In order to clarify and provide additional specificity to the proposed project the sponsor has submitted a detailed month-by-month matrix of the number and type of non-instructional events and the corresponding maximum on-site population levels.

Physical Improvements

 

The proposed physical improvements for the Marin Horizon School include modifications to existing buildings and facilities, demolition and removal of existing buildings, and construction of new buildings. The proposed improvements include:

 

  1. demolish an existing substandard approximately 5,900 square foot one story classroom building and replace it with a new 11,478 square foot classroom building that would result in a 48 percent increase in the size of the school buildings;
  2. demolish ten feet linear feet (300 square feet) from the existing classroom building adjacent to the driveway entrance facing Melrose Avenue;
  3. remove two temporary storage sheds located in the SCA corridor;
  4. construct a new storage shed adjacent to the new transformer;
  5. construct a new stepped terrace providing amphitheater seating along the western side property line;
  6. construct 14 new parking spaces on the playground, for a total of 49 spaces;
  7. construct a new transformer 11 feet from the Montford Avenue property line;
  8. construct an additional emergency pedestrian walkway with a breakaway exit gate from the third floor of the new building to Montford Avenue;
  9. obtain an Encroachment Permit to extend existing diagonal striping for the passenger loading area two feet into the public right of way on Melrose Avenue;
  10. construct a bio-swale between a portion of the parking lot and the creek in the SCA corridor, remove the impermeable paving and replacing it with permeable paving material;
  11. install a new site drainage filter box on the main drainage pipe leading to Reed Creek; and
  12. authorize an existing identification sign for the school on Melrose Avenue, measuring 36 inches by 43 inches” – approximately 10.75 square feet.

 

 

The new building would hold 11 classrooms: 8 classrooms for the 4th to 8th grades and 3 specialized classrooms for music, science and a foreign language studio. Demolishing the existing middle school building would eliminate 6 of the existing K-8 classrooms. Thus with the new building, the school is gaining 5 additional classrooms.

 

The proposed on-site parking areas would be redeveloped and expanded by 14 new spaces including 2 tandem spaces and 2 handicapped accessible spaces. The proposed parking plan would provide 49 on-site parking spaces, as compared to the 35 spaces currently available at the School. Other internal circulation improvements proposed as part of the project include the demolition of ten feet of existing building facing the driveway entrance onto Melrose Avenue to widen the driveway to accommodate two lanes; and modifications to on-site circulation to improve access to parking areas.

TABLE 2: LOT COVERAGE

* Includes proposed bio-swale (348 Sq. Ft.)

 

A total of five trees are proposed for removal: two redwood trees, one Monterey pine tree, one Strawberry tree, and one fir tree. The project sponsor proposes a landscaping plan that includes replacement planting of 26 trees consisting of 8 California Buckeyes; 10 Coast Live Oaks; and 8 Coast Redwoods with an additional 380 shrubs, and other groundcover plantings consisting of native plant species.

 

The project sponsor estimates that the proposed project would require total grading involving approximately 615 cubic yards of excavation to be off-hauled, and 553 cubic yards of fill to be imported. Excavation would involve approximately 491 cubic yards for the new building and 124 cubic yards for the bioswale and permeable paving. Fill would involve 240 cubic yards of drain

 

rock and sand for the building, and 313 cubic yards of compacted soil material for the terrace. Approximately 322 cubic yards would be excavated and recompacted on site for the building pad.

 

The subject property is located at 305 Montford Avenue in Mill Valley, and is further identified as

Assessor's Parcel 047-161-07.

 

  1. WHEREAS the Marin County Planning Commission also held duly noticed public hearings on May 9, 2005, and May 23rd, 2005, to consider the merits of the project, and hear testimony regarding the project.

 

  1. WHEREAS the Marin County Planning Commission finds that the proposed project, as conditioned herein, is consistent with the goals and policies contained in the Marin Countywide Plan (CWP) as discussed in the Initial Study for the following reasons:

 

  1. The continued operation of a private school on the subject property would be consistent with a permitted educational use under the governing Public Facility, Single-family Residential land use designation. (Policy CD-8.5)

 

  1. The proposed project would not adversely affect the provision of public services for fire protection, roadways, and schools. (Policies EQ-1.1, EQ-3.10, A-1.1)

 

  1. The project would conform to the CWP’s Streamside Conservation Area policies and would be developed to preserve natural riparian vegetation and to protect the fish and wildlife values associated with Reed Creek. (Policies EQ-2.4, EQ-2.5, EQ-2.8, EQ-2.9, EQ-2.10, EQ-2.13, EQ- 2.24, EQ-2.26)

 

  1. The project would not alter existing stream flow, beds, or banks, and has been designed to minimize soil disturbance and to retain sediment runoff and pollution impacts both during and following construction. (Policies EQ-2.19, EQ-2.20, EQ-2.22)

 

  1. The project would not directly or indirectly impact special status species or habitat diversity because the proposed improvements would be located either on or adjacent to previously- developed areas of the campus, and the project would be designed to avoid impacts to anadromous fish. (Policy EQ-2.87)

 

  1. The project would not result in air, water, and noise pollution. (Policy EQ-3.2)

 

  1. The project has been designed to avoid hazards associated with earthquakes, erosion, landslides, floods, and fires. (Policy EQ-3.7)

 

  1. As modified by conditions of approval, the project would retain the predominant visual qualities for the natural and built environments. (Policy EQ-3.11)

 

  1. As modified by conditions of approval, the project would minimize the extent of removal of large, mature, native trees, and provide for ample amount of replacement to compensate for the loss of native biomass. (Policy EQ-3.14)

 

  1. The project would minimize the extent of grading that is required to conform to the standards of the Department of Public Works. (Policy EQ-3.16)

 

 

  1. The project is consistent with the Tamalpais Area Community Plan because the use and development on the school site would be compatible with the Homestead Valley area. (TACP policies LU 19.1, LU 19.2, LU 20.1, LU 20.2)

 

  1. The project is consistent with the Tamalpais Area Community Plan because the Use Permit for project approval considers the value of the school for the entire community, and the conditions of approval address valid concerns addressed by the community. (LU 19.2e)

 

  1. WHEREAS the Marin County Planning Commission waives the requirements for Master Plan approval for the proposed project pursuant to Marin County Code Section 22.44.040.A, for the following reasons:

 

  1. The proposed project entails constructing a school building that would be less than 15,000 square feet.

 

  1. The proposed project would be consistent with the Marin Countywide Plan and the Tamalpais Community Plan.

 

  1. The proposed project is consistent with the mandatory Findings for Use Permit and Design Review approval.

 

  1. The new school building would be located outside any defined resource areas, including the SCA for Reed Creek.

 

  1. The proposed project would be adequately served by existing public safety personnel because it is within an urbanized area.

 

  1. The subject property is zoned for quasi-public uses, such as schools, and no residential uses are proposed. Conditions of project approval exhaust future residential development potential without receiving Master Plan approval for the project.

 

  1. The proposed project would be located to avoid any areas that are impacted by noise or natural hazards.

 

  1. The proposed project would be located on a property that meets the parking and circulation requirements of the Marin County Code, as verified by Department of Public Works staff.

 

  1. The proposed project would preserve significant views in the area as demonstrated by the visual analysis conducted for the Initial Study.

 

  1. WHEREAS, the Marin County Planning Commission finds that the proposed project is consistent with the mandatory findings necessary to approve the Design Review application (Section

22.42.060 of the Marin County Code).

 

  1. The proposed development will properly and adequately perform or satisfy it functional requirements without being unsightly or creating incompatibility/disharmony with its locale and surrounding neighborhood.

 

The visual resources policies of the CWP and the Community Plan encourage new structures to be compatible in scale and design with the surrounding environment. Structures should follow the natural land contours and should not obstruct significant views from public viewing locations. The visual impact analysis concluded that the proposed project is consistent with these policies. The viewshed reconnaissance from adjacent streets, hills, and other possible vantages where the school site could be visible from public viewpoints and open space indicated that the school would be largely screened by existing vegetation or would be obstructed by existing buildings. No locations were identified where the project would obstruct any significant views. Staff observations from the surrounding area, including private properties, confirm the information provided by the visual analysis.

 

Although the project is generally consistent with this Finding, several features of the design in the area behind the new school building and adjacent to Montford Avenue should be modified to enhance the appearance of the school from the vantage point of Montrford Avenue. The interface between the institutional character of the school property and the residential character of the surrounding area is sensitive and requires an appropriate architectural and site design. The development on the school property intergrades effectively with residential area along Melrose Avenue, the natural area of Reed Creek, and the public area of the community center. However, the treatment of the area along Montford Avenue is inappropriate and should be modified to be compatible with the character of the community.

 

The design includes features that would normally be considered appropriate for an ally or service entrance, including a storage shed and utility entrance, two exterior staircases, and an emergency exit. Exterior materials that include concrete cinderblock and a wire fence are included in the proposal for this area. Staff recommends requiring a redesign of this area that would not adversely affect the architectural integrity of the design of the new school building, but would enhance this area adjacent to Montford Avenue. The following recommendations should govern the modifications to the design:

 

  • The storage shed and utility access should be eliminated from the plans.

 

  • The unconsolidated fill retained by the existing chain link fence should be removed and the fence should be replaced with a 4-foot high fence that is constructed with wood to match the wood siding of the new school building.

 

  • The facades of all portions of the building facing Montford Avenue, including the staircases and emergency exit, should use the approved wood siding as an exterior material.

 

  • The emergency exit ramp and staircase should be reconfigured so that the staircase would be immediately adjacent to the building and the ramp would be adjacent to the street. This would eliminate the necessity of having a structural wall immediately adjacent to Montford Avenue.

 

  • The staircases should be reconfigured to be parallel rather than perpendicular to Montford Avenue in order to increase the setback to the street. However, this modification should not be required if it is found to unreasonably compromise the integrity of the architectural design.
  • The top floor of the new school building shall not be lit during the after regular school hours, except for maintenance purposes, and the top floor of the new school building shall not be used for special events.

 

 

These modifications would ensure that sound and creative design principles have been used in designing the proposed project, which result in high quality site planning and architectural design, and the innovative use of materials, construction methods, and techniques.

 

  1. The proposed development will not impair, or substantially interfere with the development, use, or enjoyment or other property in the vicinity, including, but not limited to, light, air privacy, and views, or the orderly development of the neighborhood as a whole, including public lands and rights-of-way.

 

The new building would be screened from view by the existing topography on the site and the existing vegetation and landscaping. From Montford Avenue the proposed building pad would be approximately twenty feet below the level of the street, since the property slopes from an elevation of approximately 134 feet at Montford Avenue to 114 feet at the base of the proposed structure. Consequently, approximately one and-a-half stories of the three-story structure would be visible from Montford Avenue.   Photosimulations 2s, 3s and 4s show that the existing Acacia trees and other landscaping would largely hide the portion of the project above Montford Avenue. The proposed building is designed so that the third story is approximately half the square footage of the second story. The height and bulk of the proposed building would not create a significant visual impact viewed from Montford Avenue. The prominence of construction is be minimized by placing buildings so that they will be screened by existing vegetation, and depressions in the site topography. The exterior appearance of proposed structures, along with their associated landscaping, parking, signs, is compatible and harmonious with the design, scale, and context of surrounding properties.

 

  1. The proposed development will not directly, or cumulatively, impair, or limit further investment or improvements in the vicinity, on the same or other properties, including public lands and rights-of-way.

 

As modified by the conditions of project approval, and discussed in the Initial Study, the project analysis and the other mandatory Findings, the project avoids conflicts between land uses, ensures that environmental values of the site are preserved, and adverse physical or visual effects which might otherwise result from unplanned or inappropriate development, design, or placement are minimized. The design of the project respects and preserves the natural beauty of the County and the environmental resources found in the area.

 

  1. The proposed development will be properly and adequately landscaped with maximum retention of trees and other natural features and will conserve non-renewable energy and natural resources.

 

Site Planning, building design, and construction practices promote resource conservation through climate responsive design and use of renewable energy and resources as discussed in Finding G below. Further, the bioswale, the increase in pervious paving surface, and the drainage box/filter are environmentally beneficial and would ensure that fisheries values in the creek would not be reduced as a result of unfiltered runoff, sedimentation, erosion, and contamination from use of the roadway and parking areas. These features would protect water quality and fishery values associated with Reed Creek.

 

The proposed project would preserve the primary oak woodland habitat environment on the property that is concentrated in the riparian corridor adjacent to Reed Creek because most of the proposed construction would occur on an already developed site outside of the SCA. The project would result in the removal of five trees comprising two redwood trees, one Monterey pine tree, one strawberry tree, and one fir tree. The preliminary landscaping plan proposes planting of 26 trees resulting in an average of 5.2 replacement trees for each tree that would be removed by the project. The preliminary landscape plan calls for the planting of 380 shrubs. The proposed project would result in a net increase in the biomass due to the planting of trees, shrubs and groundcover.

 

The project would maintain significant trees and other landscaping and vegetation, which would reduce and soften the visual impacts of the new construction, stabilize and prevent the erosion of graded soils around the structure and enhance the privacy of the occupants of the subject and surrounding properties. Further, the landscaping plan would increase vegetation on the site. Landscaping would enhance the appearance of the new development and surrounding areas by being designed, installed, and maintained to blend new structures into the context of an established community.

 

  1. The proposed development will be in compliance with the design and locational characteristics listed in Chapter 22.16 (Planned District Development Standards).

 

The exterior appearance of the new school building, along with the associated landscaping, and parking, as well as the existing school sign, is compatible and harmonious with the design, scale, and context of surrounding properties. The existing sign on the front of the school compliments the school property because it is relatively small and well designed.

 

  1. The proposed development will minimize or eliminate adverse physical or visual effects, which might otherwise result from unplanned or inappropriate development, design, or placement.

 

  1. The area, heights, mass, materials, and scale of structures;

 

The proposed project is consistent with this Finding for the reasons expressed in Design Review Findings A and B herein.

 

  1. Drainage systems and appurtenant structures;

 

The stability of the creek banks in the vicinity of the school site was investigated by a geotechnical consultant, Earth Mechanics Consulting Engineers. The report concluded that the creek banks on the site are generally stable. The Initial Study discusses this issue in detail, and as a condition of project approval the applicaant shall be required to submit a storm water pollution control plan prior to construction. All construction shall ensure drainage into the natural watershed in a manner that will avoid significant erosion or damage to adjacent properties, and impervious surfaces shall be minimized in the parking area within the SCA for Reed Creek.

 

Subsequent to the publication of the Initial Study, a tree fell in the channel of Reed Creek adjacent to the school property. Areas of localized erosion and the adjacent area where a tree fell were caused by surface water on the AC paving above the creek being directed toward and concentrated onto the creek bank. The engineer recommended that the collected surface water concentrated onto the creek bank slope would be improved by constructing a curb along the south side of the pavement in the area of the observed

 

erosion. The engineer’s recommendations address an existing condition on the MHS site unrelated to the proposed project and therefore does not require any revisions to the Initial Study. The engineer’s recommendations, however, are a part of the merit considerations of the project because the issue represents a land use compatibility problem or other policy concern for the project. A condition of project approval requires the construction of a curb along the south side of the pavement in the area of the observed erosion.

 

  1. Cut and fill or the reforming of the natural terrain, and appurtenant structures (e.g., retaining walls and bulkheads);

 

The proposed project will require total grading of approximately 615 cubic yards of excavation to be off-hauled, and 553 cubic yards of fill to be imported. Excavation would involve approximately 491 cubic yards for the new building and 124 cubic yards for the bioswale and permeable paving. Fill would involve 240 cubic yards of drain rock and sand for the building, and 313 cubic yards of compacted soil material for the terrace. Approximately 322 cubic yards would be excavated and recompacted on site for the building pad.

 

Grading would occur in compliance with Title 23, Chapter 23.08 of the County Code (Excavating, Grading and Filling), but shall be held to a minimum. Every reasonable effort would be made to retain the natural features of the land, including native vegetation, mature trees, and Reed Creek. Where grading is required, it would not create flat planes and sharp angles of intersection with natural terrain. Slopes would be rounded and contoured to blend with existing topography.

 

  1. Areas, paths, and rights-of-way for the containment, movement or general circulation of animals, conveyances, persons, vehicles, and watercraft; and

 

The project is consistent with this Finding as discussed in Use Permit Finding Vl.E below.

 

  1. Will not result in the elimination of significant sun and light exposure, views, vistas, and privacy to adjacent properties.

 

The project is consistent with this Finding for the reasons expressed in Finding V.A above.

 

  1. The project design includes features, which foster energy and natural resource conservation while maintaining the character of the community.

 

The new school building would have a generally east-west orientation and would have a large expanse of windows on the southern façade of the building, which would maximize passive solar heating. Therefore, the proposed site planning and building design promote resource conservation through climate responsive design and use of renewable energy and resources.

 

  1. The design, location, size, and operating characteristics of the proposed use are consistent with the Countywide Plan and applicable zoning district regulations, are compatible with the existing and future land uses in the vicinity, and will not be detrimental to the public interest, health, safety, convenience, or welfare of the County.

 

Based on the photosimulations and a visual analysis of the project, the Initial Study concluded that the project would have a less than significant visual impact pursuant to CEQA. However, the Initial Study also noted that the issue of community character involves important community planning and land use considerations and the County may further consider community character policy issues in the context of evaluating the merits of the project and/or the conditions of approval.

Staff has carefully reviewed the plans, visited the neighborhood, and evaluated the project with respect to architectural and building design. The architectural style of the school is a departure from the prevailing residential styles found elsewhere in Homestead Valley. However, the design is consistent with the institutional character of a school and would add visual interest to the Homestead Valley community. Substantial existing vegetation, proposed landscaping and the topographical depression where the new school building would be located would enhance the integration of the new school building with the surrounding area.

 

As modified by the conditions of approval, the proposed project would be compatible with the physical character of the Homestead Valley area and consistent with the policies contained in the community plan. Other operational characteristics are discussed in the Use Permit Findings below.

 

  1. WHEREAS, the Marin County Planning Commission finds that the proposed project is consistent with the mandatory findings necessary to approve the Use Permit application (Section 22.42.060 of the Marin County Code).

 

  1. The proposed use is consistent with the Countywide Plan and applicable Community Plans.

 

The proposed project is consistent with the Countywide Plan and the Tamalpais Area Community Plan for the reasons expressed in Finding III above.

 

  1. The approval of the Use Permit for the proposed use is in compliance with the California Environmental Quality Act (CEQA).

 

An Initial Study has been prepared pursuant to the requirements of the California Environmental Quality Act, and the Environmental Coordinator of the County of Marin has recommended the grant of a Negative Declaration of Environmental Impact. All potentially significant adverse effects of the project and the appropriate mitigation measures are discussed in the Initial Study. The mitigation measures are included as conditions of project approval in the recommended Resolution attached to this Staff Report.

 

  1. The design, location, size, and operating characteristics of the proposed use are compatible with the existing and future land uses in the vicinity.

 

The proposed project is consistent with this Finding for the reasons expressed in Design Review Finding V.A above.

 

  1. The proposed use would not impair the architectural integrity and character of the zoning district in which it is to be located.

 

The proposed project is consistent with this Finding for the reasons expressed in Design Review Findings V.A  and V.B above.

 

  1. That granting the Use Permit will not be detrimental to the public interest, health, safety, convenience, or welfare of the County, or injurious to the property or improvements in the vicinity and zoning district in which the real property is located.

 

The project is generally consistent with this Finding for the reasons expressed in the other Findings above. However, with respect to noise created by special events at the school as well as traffic, loading, parking congestion, conditions of approval are necessary to ensure that the alterations to the operations of the school would have adverse affects to the character of the local community.

 

The acoustical analysis prepared in connection with the Initial Study indicates that the average additional noise created by the increase in enrollment would be barely perceptible to the surrounding area, and would not result in significant adverse affects to the environment with respect to noise. However, it is important to note that determinations regarding the project’s consistency with community plan policies and compatibility with the character of the local community cannot be solely derived from whether an effect would exceed established thresholds of significance under CEQA. Subjective factors, including land use conflicts, are also important considerations that must be evaluated in accordance with community plan policy LU 19.2. Several comments received from community members note that Stolte Grove, the small park located west of the subject property, does not allow amplification during special events. The school’s operations should also be held to a reasonable standard that is consistent with the community character. Therefore, in order to maintain the quiet residential character of Homestead Valley, a condition of project approval prohibits the use of amplification during special events in the evening or on Sundays.

 

The school has developed a traffic management plan that would address adverse affects that the school’s current and future operations have on the Homestead Valley area. The traffic management plan contains mandatory measures for each family whose children attend Marin Horizon School. A contractual agreement signed by each family commits them to abide by the regulations of the traffic management plan. Violation of regulations can result in fines, loss of driving privileges to/from the school and expulsion from the school. The traffic management plan comprises five components: drop-off and pick-up of students; parking; carpooling; traffic management rules; and parent compliance. The principal features of these components are summarized in the analysis of the staff report.

 

The conditions of approval include requirements that the traffic management plan continue to operate effectively, with the assurance that independent monitoring of the traffic management measures would be enforced by the County. Proper implementation of the modified traffic management plan would ensure that the proposed project is compatible with adjacent land uses and intensity of development in the immediate area, and is consistent with the community plan because it would minimize adverse affects to the Homestead Valley area with respect to traffic, loading, and parking congestion

 

CONDITIONS OF APPROVAL:

 

Community Development Agency – Planning Division

 

  1. Marin Horizon submitted a Use Permit and Design Review application to undertake programmatic changes and physical improvements to their facility is approved in accordance with the following project description. The project is a plan to demolish an existing 5,900 square foot one-story

 

classroom building and construct a new 11,478 square foot classroom building for a total building area of 24,451 square feet for the Marin Horizon School on the 2.27-acre Homestead School site. The new classroom building will be a primarily two-story building with a three-story component.

  • Approximately 341 square feet of the three-story portion of the building will be a mechanical equipment enclosure with a maximum height of 39.5 feet above grade.

 

The building will have the following minimum property line setbacks: 19.5 feet front (north); 15 feet side (west); 170 feet side (east); and 170 feet rear (south). The project also includes a proposal to increase the permitted number of students enrolled in the school by 50 students, from a maximum of 250 students to a maximum of 300 students; increase staff levels from 44 Full Time Staff Equivalent (FTE), comprised of 31 full time and 16 part time employees, to 49 FTE comprised of 44 full time and 10 part time staff; construct a new stepped terrace along the western side property line; construct 14 new parking spaces on the southern portion of the playground for a total of 49 parking spaces; construct a new transformer 11 feet from the front property line facing Montford Avenue; demolish 10 feet of building located adjacent to the driveway access on the south side of the property; construct an additional pedestrian emergency walkway from the third floor to Montford Avenue; remove two redwood trees, one Monterey pine tree, one strawberry tree, and one fir tree; and install new landscaping.

 

The project also includes an Encroachment Permit to allow existing diagonal striping for the passenger loading area along Melrose Avenue to extend 2 feet into the street right-of-way. The additional encroachment into the right of way is to provide for a wider pedestrian way between the school building and the passenger drop-off and pick-up area for safety reasons. No change to the length of the passenger loading area is proposed.

 

Land Use Changes

 

The proposed land use changes include modifications to the school’s 1993 Use Permit to: (1) increase the enrollment from 250 to 300 students, and to (2) increase the staff from 44 FTE to 49 FTE. No change to the number of special non-instructional events in the evening is proposed.

 

Table 1 outlines the proposed changes. (The proposed changes to the 1993 Use Permit are bolded.) In order to clarify and provide additional specificity to the proposed project the sponsor has submitted a detailed month-by-month matrix of the number and type of non-instructional events and the corresponding maximum on-site population levels.

Physical Improvements

 

The proposed physical improvements for the Marin Horizon School include modifications to existing buildings and facilities, demolition and removal of existing buildings, and construction of new buildings. The proposed improvements include:

 

  1. demolish an existing substandard approximately 5,900 square foot one story classroom building and replace it with a new 11,478 square foot classroom building that will result in a 48 percent increase in the size of the school buildings;
    1. demolish ten feet linear feet (300 square feet) from the existing classroom building adjacent to the driveway entrance facing Melrose Avenue;
    2. remove two temporary storage sheds located in the SCA corridor;
      1. construct a new storage shed adjacent to the new transformer;
        1. construct a new stepped terrace providing amphitheater seating along the western side property line;
        2. construct 14 new parking spaces on the playground, for a total of 49 spaces;
        3. construct a new transformer 11 feet from the Montford Avenue property line;
          1. construct an additional emergency pedestrian walkway with a breakaway exit gate from the third floor of the new building to Montford Avenue;
          2. obtain an Encroachment Permit to extend existing diagonal striping for the passenger loading area two feet into the public right of way on Melrose Avenue;
          3. construct a bio-swale between a portion of the parking lot and the creek in the SCA corridor, remove the impermeable paving and replacing it with permeable paving material;
          4. install a new site drainage filter box on the main drainage pipe leading to Reed Creek; and
            1. authorize an existing identification sign for the school on Melrose Avenue, measuring 36 inches by 43 inches” – approximately 10.75 square feet.

 

The new building will hold 11 classrooms: 8 classrooms for the 4th to 8th grades and 3 specialized classrooms for music, science and a foreign language studio. Demolishing the existing middle school building will eliminate 6 of the existing K-8 classrooms. Thus with the new building, the school is gaining 5 additional classrooms.

 

The proposed on-site parking areas will be redeveloped and expanded by 14 new spaces including 2 tandem spaces and 2 handicapped accessible spaces. The proposed parking plan will provide 49 on- site parking spaces, as compared to the 35 spaces currently available at the School. Other internal circulation improvements proposed as part of the project include the demolition of ten feet of existing building facing the driveway entrance onto Melrose Avenue to widen the driveway to accommodate two lanes; and modifications to on-site circulation to improve access to parking areas.

TABLE 2: LOT COVERAGE

* Includes proposed bio-swale (348 Sq. Ft.)

 

A total of five trees are proposed for removal: two redwood trees, one Monterey pine tree, one Strawberry tree, and one fir tree. The project sponsor proposes a landscaping plan that includes replacement planting of 26 trees consisting of 8 California Buckeyes; 10 Coast Live Oaks; and 8 Coast Redwoods with an additional 380 shrubs, and other groundcover plantings consisting of native plant species.

 

The project sponsor estimates that the proposed project will require total grading involving approximately 615 cubic yards of excavation to be off-hauled, and 553 cubic yards of fill to be imported. Excavation will involve approximately 491 cubic yards for the new building and 124 cubic yards for the bioswale and permeable paving. Fill will involve 240 cubic yards of drain rock and sand for the building, and 313 cubic yards of compacted soil material for the terrace. Approximately 322 cubic yards will be excavated and recompacted on site for the building pad.

 

The subject property is located at 305 Montford Avenue in Mill Valley, and is further identified as

Assessor's Parcel 047-161-07.

 

  1. BEFORE ISSUANCE OF A BUILDING PERMIT, the applicant shall revise the site plan or other first sheet of the office and job site copies of the Building Permit plans to list these conditions of approval as notes.

 

  1. The existing sign on the front of the main school building on the site is approved.

 

  1. BEFORE ISSUANCE OF A BUILDING PERMIT, the applicant shall revise the plans to show the following modifications to the project:

 

  1. The storage shed and utility access shall be eliminated from the plans.

  1. BEFORE ISSUANCE OF A BUILDING OR GRADING PERMIT for any of the work identified in Condition 1 above, the applicant shall install temporary construction fencing around the dripline of the existing trees to be retained in the vicinity of any area of grading, construction, materials storage, soil stockpiling, or other construction activity. The fencing is intended to protect existing vegetation during construction and shall remain until all construction activity is complete. The applicant shall submit a copy of the temporary fencing plan and site photographs confirming installation of the fencing to the Community Development Agency.

 

  1. All site development construction practices shall be in accord with the recommended guidelines and inspection schedule contained in the tree assessment. The applicant shall comply with all recommendations made by the licensed professional with respect to tree protection during

 

construction activities, general tree care practices, and long-term vegetation management to ensure continued viability of the site’s native vegetation.

 

  1. Exterior amplification shall not be employed for special events held after 5:00 PM or on Sundays, except for emergency purposes.

 

  1. The provisions of the traffic management plan, attached as appendix B to the Initial Study, shall be implemented and enforced at all times by the Marin Horizon School with the following stipularions:

 

  1. The school shall not enroll more than 300 students simultaneously under any circumstances.

 

  1. The Traffic Management Plan shall be modified to include the parking measures required by Department of Public Works staff, and making arrangements for Special Event parking.

 

  1. An independent traffic monitor, hired by the County and paid for by Marin Horizon School, shall arrive at the school unannounced to examine the school’s compliance with the Traffic Management Plan, including performing physical counts of vehicles arriving at and departing from the school, loading, and parking for school activities.

 

  1. The traffic monitor shall conduct examinations during regular school hours, as recommended by Department of Public Works staff, as well as an additional examination of a large special event. The traffic monitor shall submit written reports after each examination is conducted, which evaluate the school’s compliance with its Traffic Management Plan. Upon request, the school shall supply the traffic monitor with accurate and complete lists of all students enrolled at the school and all school staff including independent contractors, and these shall be submitted as attachments to the report.

 

  1. Traffic Management Plan compliance examinations shall be conducted three times annually for a minimum of three years after the date the new school building has received Final Inspection approval. However, if the school fails to comply with the Traffic Management Plan, then additional studies may be required, at the school’s expense.

 

  1. The school will submit adequate fees to the County to defray the costs of the studies, including consulting costs and the standard 30 percent-of-contract administrative fee charged by the County for managing consultants.

 

 

  1. In the event the school fails three consecutive special event traffic examinations, it shall lose the privilege of increasing its permitted number of special events that are held during the day from 7 to 14 annually. The existing Use Permit’s allowed 7 events per year shall govern until such time as the school can conclusively demonstrate that it is complying with the Traffic Management Plan’s provisions regarding special events.

 

  1. In the event that the school fails three consecutive traffic examinations, or a total of five traffic examinations within the first three years after the new school building receives Final Inspection approval the Use Permit for the project shall be brought before the Board of Supervisors to consider a modification or revocation of this Use Permit, pursuant to Marin County Code Section 22.120.030.
  2. Future use and development of the subject property shall not include multiple residential units on the site without receiving Master Plan approval from the County.

  1. If archaeological, historic, or prehistoric resources are discovered during construction, construction activities shall cease, and the Community Development Agency staff shall be notified so that the extent and location of discovered materials may be recorded by a qualified archaeologist, and disposition of artifacts may occur in compliance with State and Federal law. A registered archeologist, chosen by the County and paid for by the applicant, shall assess the site and shall submit a written report to the Community Development Agency staff advancing appropriate mitigations to protect the resources discovered. No work at the site may recommence without approval of the Community Development Agency staff. All future development of the site must be consistent with findings and recommendations of the archaeological report as approved by the Community Development Agency staff. If the report identifies significant resources, amendment of the permit may be required to implement mitigations to protect resources. Additionally, the identification and subsequent disturbance of an Indian midden requires the issuance of an excavation permit by the Department of Public Works in compliance with Chapter 5.32 (Excavating Indian Middens) of the County Code.

 

  1. BEFORE ISSUANCE OF A BUILDING PERMIT, the applicant shall prepare and submit a construction management plan for review and approval by the Community Development Agency staff in consultation with the Department of Public Works. The plan shall include the following components.

 

  1. The plan shall include provisions for construction traffic control (including use of flag persons, appropriate signs, etc.) to ensure that vehicular traffic and pedestrian movement will continue to occur safely during the construction. A separate Encroachment Permit from the Department of Public Works may be required.

 

  1. The plan shall include provisions to notify residents along the roadway of the general time frame for all construction activity and specific dates and/or time periods where there may be temporary traffic control, due to delivery of equipment or materials, such as concrete, or removal of earth material, trees, and other large debris. Notification shall be given to the affected residents and copied to the Community Development Agency in writing at least 72 hours prior to any construction activity, which may involve temporary traffic control.

Pursuant to Marin County Code Chapter 15.07, Marin Horizon School shall pay Transportation Facilities Fees for the 14 new PM peak hour trips in the amount of $53,649.10 (14 trips x $3,832.08/trip). These fees are updated annually in January using the ENR Construction Cost Index to account for inflation

 

  1. Marin Horizon School shall implement the traffic management plan and routinely monitor the conformance to that plan. A copy of the plan shall be included with the Use Permit.
  2. Carpooling shall be increased from the current average of 1.53 to not less than 2.00 students per car. This average may include the use of a shuttle. Based on an analysis of the Marin Horizon School Traffic Plan performed by Robert Harrison, the average carpool rate could be 2.33.

 

 

  1. If this carpool ratio is not met during the first monitoring period, the school shall be placed on notice and required to correct the situation. If the ratio is still not met during the following monitoring, the school will be required to take corrective action or a reduction in student population may be applied.

 

  1. The school is encouraged to investigate an easily accessible and central ‘rendezvous’ carpool, vanpool or bus pickup/dropoff location to further enhance the traffic reduction proposed by the Traffic Plan (i.e., Mill Valley Community Center).

 

  1. Monitoring shall be performed by an independent professional three times per school year: September/October and March/April and during a special event. No monitoring event shall occur within two weeks of a holiday.

 

  1. Prior to building permit approval, applicant shall revise plans so as to minimize improvements needed for access from Montford Ave as approved by DPW. Retaining walls and curbs shall be minimized, a 4-foot shoulder shall be provided and access flare improved. The Road Commissioner/Director of Public Works retains the right to issue or deny an encroachment permit or impose conditions upon issuance of an encroachment permit

 

The County of Marin does not allow compact parking spaces, but will allow exceptions for tandem spaces when under suitable control of owner.

  1. The parking shall be sufficient to accommodate all on-site staff, and shall be a minimum of 49 spaces. Alternatively, the school may provide four spaces for pre-kindergarten classrooms and 3 spaces for each kindergarten through 8th grade classroom.

 

  1. An encroachment permit shall be required for construction, striping and any work within the road right-of-way and is subject to final review and approval by the Road Commissioner. Revise plans so that storm drains in the public right of way do not have blind connections.

 

  1. All handicap parking and loading areas shall meet State of California Title 24 and federal accessibility standard.  At a minimum revise plans to include following:

 

  1. Revise sheet A0.2, Accessible Parking Space detail to show “No Parking” phrase to be painted across the width at the bottom of loading zone.

 

  1. Signage for accessible parking spaces shall indicate “Van Accessible”. Also another sign shall be provided warning unauthorized vehicle against parking in these spaces and that they will be towed away.   Note the minimum height for a freestanding sign is 72”.

 

  1. For proposed tandem parking stalls the clearance between fences shall be a minimum of 18’.
  2. Prior to issuance of the Building Permit or Grading Permit the plans must be reviewed and approved by a Registered Soils Engineer or a Registered Civil Engineer with soils expertise. Proof of the same may be by the engineer’s stamp and signature on the plans or by letter.
