Lisa Grote, Community Development Director

 

SUBJECT:

Consideration of a Coastside Design Review Permit, pursuant to Section 6565.4 of the County Zoning Regulations, to construct a new 2,548 sq. ft. single-family residence on a 5,000 sq. ft. parcel located at 286 – 2nd Street, in the unincorporated Montara area of the County. (Appeal from decision of the Planning Commission denying the Design Review Permit.) This project is not appealable to the California Coastal Commission.

 
 

County File Number:

PLN 1999-00015 (Mahon)

 
 

RECOMMENDATION

 

Deny the appeal and uphold the decision of the Planning Commission and deny the Design Review Permit, County File Number PLN 1999-00015, by making the findings of denial as listed in Attachment A.

 

VISION ALIGNMENT

 

Commitment: Number 9 (Partnerships); “Effective and Collaborative Government.”

 

Goal: Number 20; “Government decisions are based on careful consideration of future impact, rather than temporary relief or immediate gain.”

 

The Planning Commission’s recommendation to deny the subject Design Review Permit furthers Commitment 9 and Goal 20 because the Planning Commission’s decision that the project did not comply with design review standards suggests that they were considering the future impacts of the project on the surrounding neighbors.

 

BACKGROUND

 

Proposal: The applicant is proposing to construct a new 2,548 sq. ft. two-story single-family residence including an attached two-car garage on a 5,000 sq. ft. parcel. The proposed house fronts onto and is accessed from Farallone. No trees are proposed for removal.

 

This project was one of two Design Review (DR) applications (the other application is PLN 1999-00215) for new single-family homes on two adjacent parcels submitted by the applicant in February 1999. At the time that both of the projects were submitted Design Review applications were processed administratively by Planning Staff. At that time the Design Review chapter of the County Zoning Regulations did not include a required public notification. However, an Intra-Departmental Correspondence dated January 14, 1994 did institute a required public notification for Coastside Design Review applications. This differs from the process currently in place, as the Design Review chapter was updated on August 8, 2000 to include the establishment of the Coastside Design Review Committee. This moved the decision making authority from an administrative Staff decision to a publicly noticed hearing with the decision being rendered by the Committee.

Both projects had their initial DR approvals rescinded due to inadequate public notification. Upon thorough re-noticing, review and extensive opportunity for comment, both projects have incurred similar degrees of strong opposition from the neighbors and Midcoast Community Council, based on their bulk, size and design relative to applicable DR standards, site topography and comparative surrounding development.

 

In response to the subject project, the applicant has made few substantial design modifications to the house beyond minor articulation changes to the exterior. Subsequently, however, the subject project’s DR Permit was approved by the Planning Director in April 2004. That decision was appealed to the Planning Commission by 22 neighbors. The applicant appealed that decision to the Board of Supervisors and again submitted minor modifications to the project in December of 2004. The Board of Supervisors subsequently rendered a final decision and denied the applicant’s appeal and DR application in February 2005 finding that the applicant had not adequately addressed the concerns raised by the Planning Commission. Specifically, that neither design reviewed by the Planning Commission in November 2004 or the revisions submitted in December of 2004 blended with the natural landforms or was in harmony with character and scale of the surrounding neighborhood.

 

Planning Commission Action: The Planning Commission’s denial of this project on November 10, 2004, took into consideration the issues posed by the appellants, issues around the inadequacy of the latest submitted plans (a significant tree and existing well were not shown on the site plan, exterior wall and window details were missing from the elevations) and found there was not adequate evidence to support two applicable design review standards: (1) the house is not designed and situated so as to retain and blend with the natural vegetation and landform of the site, and (2) the house is not in harmony with the shape, size and scale of adjacent buildings in the community.

 

Board of Supervisors Action: The Board of Supervisors denied this application on February 8, 2005. While the applicant did submit revised plans in December 2004, the plans included only minor roof articulation improvements, which were essentially no different from an earlier iteration submitted by the applicant on October 1, 2001, whereby the garage was attached to the house, but moved 10 feet back from the front property line. These changes did not address the comments or recommendations provided by the Planning Commission in April 2004. In addition, there was also significant community opposition to the proposed project. The objections were similar to those that were voiced throughout the review process. Specifically, comments focused around the opinion that the design of the proposed residence was not in harmony with the character of the surrounding neighborhood due to its shape, scale, and size. Furthermore, that the design of the proposed residence would loom over the street due to the lack of articulation and that the design would alter the natural topography of the site rather than utilizing the existing contours. The community also felt that the application materials submitted by the applicant were insufficient, as a landscaping plan, color and material samples, and a site plan indicating the location of the well and the trees proposed for removal were not provided.

 

Based on comments provided by the community, the applicant’s unwillingness to agree to the recommended conditions of approval, and the project’s continued non-compliance with the previously mentioned DR standards, the Board of Supervisors unanimously voted to deny the applicant’s appeal and uphold the Planning Commission’s decision to deny the project.

Writ Proceeding:

Following the Board’s denial of the applicant’s appeal, on May 6, 2005 the applicant filed a Petition for Writ of Administrative Mandamus with a Complaint for other claims including inverse condemnation, civil rights violations, injunction and declaratory relief. By agreement of the parties, the Court bifurcated the case, staying all proceedings relating to the non-writ claims until after the hearing on the Petition for Writ of Administrative Mandate (“the Petition”).

The Petition was heard by the Court on July 26, 2007. Additional briefing was requested by the Court and submitted by the parties. A Statement of Decision representing the decision of the Court was issued on March 17, 2008. The Statement of Decision found that the applicant had been provided insufficient time at the Board hearing to present arguments in support of the appeal, and that the applicant had not been provided a fair administrative hearing. The Court set aside the decision of the Board denying the applicant’s appeal, and ordered that the Board rehear the appeal from the decision of the Planning Commission.

DISCUSSION

 

A.

KEY ISSUES OF THE APPEAL

   
 

The appellant submitted his appeal of the Planning Commission’s decision, with the specific grounds for appeal provided through his representative, Dave Beaumont (italicized) (see Attachment G). Mr. Beaumont appealed the Planning Commission’s decision, but also submitted plan revisions after the Planning Commission’s November 2004 denial of the project. The appellant has subsequently expressed a desire for the Board to consider only the plan that was considered and rejected by the Planning Commission, and not the subsequent revisions by Mr. Beaumont. Thus, the portions of the appellant’s issues on appeal that relate to revisions to the plans are not summarized here, as they have been abandoned by the appellant. The appellant’s issues and staff response follow:

   
 

The contention of the Planning Commission is that “... there was not adequate evidence to support: (1) that the proposed structure does not blend with the natural contours of the site and (2) that the proposed structure does not relate to adjacent buildings and to the neighborhood.”

   
 

   
 

     
   

Staff Response: The Planning Commission found that the proposed structure does not “blend[] with the natural contours of the site” as required by the applicable 1999 Design Review standards. The house’s size and scale in relation to its proposed siting on the lot would cause the house to appear prominently from the street, which is not in keeping with Design Review standard.

     
   

As an alternative to staff’s recommended action to deny the appeal, if the Board decides to approve this project, please refer to the Alternative Section of this report and to Attachment B for recommended and revised conditions of approval, including requiring the applicant to lower and reduce the height of the downhill portion of the house.

     
 

2.

The maintenance of a mature, towering, heritage tree in the foreground of the street facade at the southeast of the site, gives context to the structure and its reduced prominence in relation to the natural landform.

     
   

Staff Response: Staff is not clear what “heritage tree” Mr. Beaumont is referring to. There is a “significant” pine (but not designated “heritage” status) located in the southeast corner of the parcel as shown on Mr. Mahon’s recently submitted site plan. Mr. Mahon has indicated that he intends to preserve that tree. However, the tree does not substantially alter the visual impact of the façade of the house as it is proposed to be situated on the lot.

     
 

     
   

       
   

       
   

       
   

       
   

     
   

     

B.

COMPLIANCE WITH COUNTY REGULATIONS

   
 

1.

Conformance with General Plan

     
   

Visual Quality and Urban Land Use. Visual Quality Policy 4.35 (Urban Area Design Concept) seeks to: (a) maintain and, where possible, improve upon the appearance and visual character of development in urban areas [of which the Montara area is included]; and (b) ensure that new development in urban areas is designed and constructed to contribute to the orderly and harmonious development of the locality. Urban Land Use Policy 8.14 (Residential Land Use Compatibility) seeks to protect and enhance the character of existing single-family areas. The Planning Commission’s November 10 denial of the design review application infers that the project was not in compliance with these two General Plan policies.

     
 

2.

Conformance with Local Coastal Program Policies

     
   

This project site is located within the Single-Family Exclusion Area of the Coastal Zone and thus qualifies for a Coastal Development Permit Exemption under Section 6328.5.e of the County Zoning Regulations.

     
 

3.

Conformance with Zoning Regulations

     
   

a.

Development Regulations

       
     

The project site is zoned R-1/S-17 and is located within a Design Review District. The project components comply with all applicable 1999 zoning regulations, including setbacks, lot coverage, and height. There was no FAR component or daylight plane requirement in the zoning regulations at the time of the application in 1999. Although the current zoning regulations adopted in September 2001 are not applicable to the proposed project, the following table compares the proposed project with both the 1999 regulations and the current regulations.

Design Review

       
     

Section 6565.1 of the Zoning Regulations relates to DR Districts in the Coastal Zone. Section 6565.7 sets out the DR standards (as applicable at time of application’s submittal in February 1999), for which projects must be assessed. The standards are listed below in bold followed by staff’s response. Please note that the Planning Commission, as previously discussed, found that the project did not comply with select DR standards, as indicated below:

       
     

(1)

Proposed structures are designed and situated so as to retain and blend with the natural vegetation and landforms of the site and to ensure adequate space for light and air to itself and adjacent properties.

         
       

The Planning Commission found that the house design does not comply with this standard. The Planning Commission found that the house design, driven by its bulk, height and site placement, was not adequately stepped up the hill, nor adequately blended with the surrounding topography.

         
       

In regard to adequate space for light and air to itself and adjacent properties, staff believes that the design complies with this standard. The structure is located on the parcel with 5-foot right and 10-foot left side yard setbacks (along Farallone). The design of the house complies quantitatively with all applicable Zoning Regulations in terms of height, setbacks and lot coverage.

         
       

         
     

(2)

Where grading is necessary for the construction of structures and paved areas, it blends with adjacent landforms through the use of contour grading rather than harsh cutting or terracing of the site and does not create problems of drainage or erosion on its site or adjacent property.

         
       

Some grading is proposed for the construction of the house, garage and driveway. Staff does not believe that the design complies with this standard, since it does not blend with the site’s natural landforms, but rather looms prominently due to its size in relation to the size of the lot. In the event this issue is resolved to comply with this standard, conditions of approval would be recommended to ensure no drainage or erosion problems are created by the construction of this project.

         
     

(3)

Streams or other natural drainage systems are not altered so as to affect their character and thereby causing problems of drainage, erosion or flooding.

         
       

No streams or drainage systems will be altered by this project.

         
     

(4)

Structures are located outside flood zones, drainage channels and other areas subject to inundation.

         
       

The project site is not located in a flood zone.

         
     

(5)

Trees and other vegetation land cover are removed only where necessary for the construction of structures or paved areas in order to reduce erosion and impacts on natural drainage channels, and maintain surface runoff at acceptable levels.

         
       

If your Board approves this project, a condition of approval is recommended (Condition 5, Attachment B) that requires a comprehensive landscape plan be submitted, reviewed and approved prior to the issuance of the building permit. This plan would show all existing vegetation and proposed landscaping.

         
     

(6)

A smooth transition is maintained between development and adjacent open areas through the use of natural landscaping and plant materials which are native or appropriate to the area.

         
       

The project site is located on the edge of an urbanized area and is surrounded by existing residential development, except to the east, where the property is undeveloped and zoned PAD. A landscaping plan had been requested as previously indicated that would seek to promote a smooth transition.

         
     

(7)

Views are protected by the height and location of structures and through the selective pruning or removal of trees and vegetative matter at the end of view corridors.

         
       

No public views will be affected by this proposal.

         
     

(8)

Construction on ridgelines blends with the existing silhouette by maintaining natural vegetative masses and landforms and does not extend above the height of the forest or tree canopy.

         
       

This project does not involve construction on a ridgeline.

         
     

(9)

Structures are set back from the edge of bluffs and cliffs to protect views from scenic areas below.

         
       

This project is not located on a bluff or cliff.

         
     

(10)

Public views to and along the shoreline from public roads and other public lands are protected.

         
       

No public views will be affected by this proposal.

         
     

(11)

Varying architectural styles are made compatible through the use of similar materials and colors which blend with the natural setting and surrounding neighborhoods.

         
       

If your Board approves this project, a condition of approval is recommended (Condition 4, Attachment B) to require that material and color samples are submitted for the review and approval by the Planning Division to ensure that they are compatible with the surrounding area.

         
     

(12)

The design of the structure is appropriate to the use of the property and is in harmony with the shape, size and scale of adjacent buildings in the community.

         
       

While the design complies with the applicable zoning requirements, the Planning Commission found that the house design does not comply with this Design Review standard. The proposed structure will consist of 2,548 sq. ft. of livable area. The average livable area of the nearby residences, within 300 feet of the project site, is 1,852 sq. ft.; in addition, one-third of nearby residences have a livable area of 2,400 sq. ft. or greater, although these are on larger lots and therefore have a different scale in relation to their lots, as opposed to raw size. Although the proposed design does not need to comply with the FAR component of the current Zoning Regulations, this calculation can provide one indication of size and scale in the neighborhood as a matter of Design Review. The proposed size of the house is comparable to 50.96% FAR, which complies with the current Zoning Regulations. However, the Planning Commission did not believe that the proposed structure was in harmony with the shape, size and scale of adjacent buildings in the community because of the way the house is situated on a relatively small lot.

         
     

(13)

Overhead utility lines are placed underground where appropriate to reduce the visual impact in open and scenic areas.

         
       

All new utilities would have to be placed underground.

         
     

(14)

The number, location, size, design, lighting, materials, and use of colors in signs are compatible with the architectural style of the structure they identify and harmonize with their surroundings.

         
       

No signs are proposed as part of this project.

         
     

(15)

Paved areas are integrated into the site, relate to their structure, and are landscaped to reduce visual impact from residential areas and from roadways.

         
       

A driveway is proposed as part of this project which will not be highly visible from the street or adjacent properties.

         

C.

ENVIRONMENTAL REVIEW

   
 

The project is exempt from review under the California Environmental Quality Act (CEQA) pursuant to Section 15303 (construction of new small facilities or structures).

   

D.

REVIEW BY THE MIDCOAST COMMUNITY COUNCIL

   
 

The Midcoast Community Council (MCCC) has considered this application at several past meetings, but most recently on March 18, 2004 (see Attachment H for their full letter). They objected to the application on the basis that: (1) the submitted plans do not include any information on materials, finishes, landscaping, tree removal, grading or driveway slope and access; (2) earlier issues regarding compatibility with the size, scale and character of the surrounding community have not been addressed; and (3) other issues and alternatives, such as reorienting the lots, lowering the houses toward grade and increased stepping of the design for better conformance with the topography have not been addressed.

   
 

While County staff believed that the project, as originally conditioned, conformed to the design review standards, the Planning Commission concluded differently at their November 10, 2004 hearing. As to the MCCC’s first issue, the applicant has already indicated that no trees are to be removed. The proposal conforms to the applicable Zoning Regulations for the R-1/S-17 zoning district (applicable in 1999). During the redesign process, the applicant discussed with County staff the alternative lot configurations as suggested by MCCC. Staff believed that the alternative would result in more bulk along 2nd Street, which is on the downhill side. The Planning Director’s previous approval had included a number of conditions that would have improved the design and articulation of the house, in addition to recommended conditions (Attachment B) requiring landscaping, tree protection and exterior color and material confirmation. Staff believes additional redesign reducing the upper floor area would provide a design more in compliance with Design Review standards relative to conforming with existing landforms and harmony with adjacent buildings in the community.

   

E.

ALTERNATIVE

   
 

   
 

Should the Board of Supervisors decide to conditionally approve this project, staff directs them to Attachment B, Alternative Recommended Findings and Conditions of Approval. Staff recommends that the upper floor area be reduced, thus reducing the general bulk of the proposed house. Conditions of Approval 4, 5 and 9 remain to ensure the submittal, review and implementation of exterior siding, roof materials, and colors, as well as a landscape plan and tree protection.

   
 

   
 

   

FISCAL IMPACT

 

No fiscal impact.

RECOMMENDED CONDITIONS OF APPROVAL

 

1.

This approval applies only to the proposal described in this report and indicated in materials submitted on December 1, 2004. These plans supersede all other submitted and reviewed plans. The Planning Director may approve minor adjustments to the project if they are consistent with the intent of and in substantial conformance with this approval.

   

2.

This permit shall be valid for one year from the date of approval within which time a building permit must be applied for and issued. Any extension of these permits will require submittal of a request for permit extension and payment of applicable fees no less than 30 days prior to expiration.

   

   

3.

The applicant shall submit exterior color samples (no larger than approximately 4 square inches) for roof, walls and trim to the Planning Counter for review and approval by the Planning Director prior to planning approval of the associated building permit. The colors and materials used shall be in keeping with the surrounding neighborhood. The applicant shall include the file/case number with all color samples. Color verification by a building inspector shall occur in the field after the applicant has painted the structure an approved color but before the applicant schedules a final inspection.

   

4.

The applicant shall submit a landscape plan (may be shown on the site plan of the submitted building permit application) depicting the location, type, and size of trees and shrubs for review and approval by the Planning Division. The landscaped areas shall be designed to reduce excess irrigation runoff and require minimal and appropriate use of fertilizers, herbicides and pesticides. The goal of the required landscape plan is to soften the building elevations and to increase surface filtration. The plan shall include a minimum of two (2) trees (minimum 5 gallons) in the front of the residence, one (1) tree (minimum 36-inch box) in the front of the residence, a minimum of three (3) trees (minimum 5 gallons) in the rear of the residence and a minimum of twenty (20) shrubs (minimum 1 gallon) shall be included in the design. Areas in the front and rear of the property that do not contain trees or shrubs shall be covered with a combination of turf or groundcover and/or a minimum of 2 inches of mulch on all exposed soil areas to minimize erosion.

   

5.

Prior to the issuance of a building permit, the applicant shall provide an erosion and sediment control plan, which demonstrates how erosion will be mitigated during the construction of the new addition subject to the review and approval of the Planning Director. This mitigation will be in place for the life of the construction project.

   

6.

The applicant is responsible for ensuring that all contractors minimize the transport and discharge of pollutants from the project site into local drainage systems and water systems by adhering to the San Mateo Countywide Stormwater Pollution Prevention Program “General Construction and Site Supervision Guidelines” including:

   
 

a.

Stabilizing all denuded areas and maintaining erosion control measures continuously between October 15 and April 15.

     
 

b.

Removing spoils promptly and avoiding stockpiling of fill materials when rain is forecast. If rain threatens, stockpiled soils and other materials shall be covered with a tarp or other waterproof material.

     
 

c.

Storing, handling and disposing of construction materials and wastes so as to avoid their entry to a local storm drain system or water body.

     
 

d.

Avoiding cleaning, fueling or maintaining vehicles on site, except in an area designated to contain and treat runoff.

     

7.

The applicant is responsible for ensuring that all contractors are aware of all stormwater quality measures and implement such measures. Failure to comply with the construction BMPs will result in the issuance of the correction notices, citations or a project stop order.

   
 

a.

All landscaping shall be properly maintained and shall be designed with efficient irrigation practices to reduce runoff, promote surface filtration and minimize the use of fertilizers, herbicides and pesticides that can contribute to runoff pollution.

     
 

b.

Where subsurface conditions allow, the roof downspout systems from all structures shall be designed to drain to a designated, effective infiltration area or structure (refer to BMPs Handbook for infiltration system designs and requirements).

     

8.

The submitted plans do not indicate any trees to be removed. Prior to the issuance of a building permit, the applicant shall submit a plan showing the location of all existing trees on the property. The applicant shall submit a tree protection plan for the tree located towards the rear of the parcel, near Farallone Avenue. Such measures shall be identified on the building permit site plan and shall be implemented prior to the start of any construction or grading activities on the site. Removal of any additional trees with a diameter equal to or greater than 12 inches as measured 4.5 feet above the ground shall require a separate tree removal permit.

   

9.

The noise from construction activity shall not exceed that as indicated in the County Noise Ordinance.

   

10.

To ensure the height of the structure and/or structures do not exceed the maximum height permitted, staff requires the applicant to adhere to the height verification procedure during the building permit process. The applicant shall provide “finished floor elevation verification” to certify that the structure is actually constructed at the height shown on the submitted plans. The applicant shall have a licensed land surveyor or engineer establish a baseline elevation datum point in the vicinity of the construction site. The applicant shall maintain the datum point so that it will not be disturbed by the proposed construction activities until final approval of the building permit.

   
 

a.

The datum point and its elevation shall be shown on the submitted site plan. This datum point shall be used during construction to verify the elevation of the finished floors relative to the existing natural or to the grade of the site (finished grade).

     
 

b.

Prior to planning approval of the building permit application, the applicant shall also have the licensed land surveyor or engineer indicate on the construction plans: (1) the natural grade elevations at the significant corners (at least four) of the footprint of the proposed structure on the submitted site plan, and (2) the elevations of proposed finished grades.

     
 

c.

In addition, (1) the natural grade elevations at the significant corners of the proposed structure, (2) the finished floor elevations, (3) the topmost elevation of the roof and (4) garage slab elevation must be shown on the plan, elevations, and cross-section (if one is provided).

     
 

d.

Once the building is under construction, prior to the below floor framing inspection or the pouring of the concrete slab (as the case may be) for the lowest floor(s), the applicant shall provide to the Building Inspection Section a letter from the licensed land surveyor or engineer certifying that the lowest floor height--as constructed--is equal to the elevation specified for that floor in the approved plans. Similarly, certifications on the garage slab and the topmost elevation of the roof are required.

     
 

e.

If the actual floor height, garage slab, or roof height--as constructed--is different than the elevation specified in the plans, then the applicant shall cease all construction and no additional inspections shall be approved until a revised set of plans is submitted to and subsequently approved by both the Building Official and Planning Director.

   

11.

The plans submitted at the building permit stage shall clearly show the location of the existing well and that the proposed development complies with the required Environmental Health setbacks from that well.

   

12.

All new power and telephone utility lines from the street or nearest existing utility pole to the main dwelling and/or any other structure on the property shall be placed underground.

   

13.

The applicant shall, pursuant to Section 5023 of the San Mateo County Code, submit a stormwater control/drainage plan, prepared by their civil engineer or erosion control consultant. The plan shall be included as part of the project’s building permit application and construction plans. The County Building Inspection Section and County Planning Division shall ensure that the approved plan is implemented prior to the issuance of a building permit. The required drainage plan shall show the necessary mechanisms to contain all water runoff generated by on-site impervious surfaces and shall include facilities to minimize the amount and pollutants of stormwater runoff through on-site percolation and filtering facilities to control stormwater runoff from the project site once the project is completed. In addition, the plan shall indicate that:

   
 

a.

All landscaping will be properly maintained and shall be designed with efficient irrigation practices to reduce runoff, promote surface filtration, and minimize the use of fertilizers, herbicides and pesticides.

     
 

b.

Where subsurface conditions allow, all building roof downspout systems shall be designed to drain into a designated, effective infiltration or structure (refer to BMPs Handbook for infiltration system designs and requirements).
