HomeMy WebLinkAboutIV.D Environmental Park Memorandum TO: Planning and Community Development Committee FROM: Kevin Snyder, AICP, Assistant Director DATE: March 17, 2009 SUBJECT: DISCUSSION: Potential Amendments to ACC 18.33 (Environmental Park), ACC 18.50 (Landscaping and Screening) and ACC 18.52 (Off-Street Parking and Loading) A.B ACKGROUND At the Committee’s February 23, 2009 meeting, the Committee requested staff to make revisions to the revised draft amendment text presented at the meeting. In addition, the Committee asked staff to analyze potential changes to building setback, off-street parking and landscaping requirements to support the potential increase in the current 35 percent maximum lot coverage standard specified in ACC 18.33.040.D. Further, the Committee asked staff to provide information on the advantages of the LEED Platinum certification. The following is a summary of key points and questions that staff would like to review and discuss with the Committee at its March 23, 2009 meeting: B.TEO ECHNICAL DITING VERVIEW For purposes of clarification, please be advised that staff has used the following technical editing techniques to explain proposed revisions: Strikethough and No Highlighting: Words that were struck for the February 23, 2009 have been retained for reference purposes and are indicated using strike-through – i.e. word Single Underlined and Yellow Highlighted: Technical edits that were made for the February 23, 2009 Committee meeting have been retained for reference purposes and are indicated by yellow highlighting – i.e. word Double Underlined and Teal Highlighted: Technical edits that were made for the February 23, 2009 Committee meeting have been retained for reference purposes and are indicated by yellow highlighting – i.e. word C.PACC18.33(EPD)A ROPOSEDISTRICTMENDMENTS The following is a summary of key potential code amendments for this chapter developed by rd staff subsequent to the Committee’s February 23 meeting. In addition, key questions that staff would like to discuss with the Committee are presented: Revisions to ACC 18.33.040.F.1-4 – Staff is proposing several amendments to this section of the code including: Reduction in building setbacks to support the potential increase in the maximum lot coverage standard and increase the opportunity for more innovative site design. Introduction of new code language that would authorize the Community Development 1 Director to approve the on-site clustering of setbacks to support the construction of innovative site design features. Elimination of the requirement for a 30-foot setback if adjacent to or separated by a street less than 50 feet in width of any residentially zoned property. This standard is not applicable to the EP zoning designation based on current surrounding zoning patterns. This requirement is currently specified in the portion of the City Code that addresses the Light Industrial (M-1) and Heavy Industrial (M-2) zoning designations. Revision to proposed ACC 18.33.050.F to clarify the incremental application of Table rd 18.33.050-1 per the Committee’s request at the February 23 meeting. Revisions to proposed Table 18.33.050-1 – Staff is proposing to modify the percentages previously presented to the Committee. As originally conceived, the Table would allow for the incremental increase in the maximum lot coverage from 50 percent up to 75 percent. Except for the use of native and drought resistant vegetation (initially proposed at 1 percent) and the use of LEED oriented design principles and guidelines (initially proposed at 4 rd percent), the table proposed 2 percent incremental increases. Subsequent to the February 23, staff has conducted substantive analysis of the potential to achieve 75 percent lot coverage on the existing lot configurations within the EP District based on current building setback, off- street parking and landscaping requirements. Staff also looked at hypothetical lot configurations within the EP District to see if the 75 percent maximum building lot coverage standard might be achievable with these different configurations. Staff has determined that 2 primarily due to the current on-site parking requirement, the 75 percent maximum building lot coverage standard could not be achieved. Staff’s analysis indicates that at best a 65 percent maximum building lot coverage could be achieved in the District with a 5 percent reduction in the current minimum 15 landscape area requirement for the EP District (ACC 18.50.050.I) and no change in the current parking requirements. Staff believes that this finding represents a substantive policy consideration for the Committee that it may want to discuss and further analyze. Staff will be preparing some additional points on this matter for rd use in the discussion on March 23. Clarification of the proposed language pertaining to a major renovation specified in proposed ACC 18.33.050.F.2. Staff is proposing to define a major renovation for the purpose of implementing Table 18.33.050-1 as an addition to an existing structure that exceeds 50 percent of the assessed valuation of the existing structure pursuant to the City’s currently adopted Building Valuation Data. This definition was developed in consultation with the City’s Building Official and is consistent with current business practices. 1 Please note that the term planning director is used in the draft code language to maintain consistency with other sections and chapters of the Auburn City Code that are not currently proposed for amendment consideration. 2 Please note that for purposes of this analysis, staff used the current parking requirement for industrial and manufacturing activities specified in ACC 18.52.020.C based on the anticipated types of future land uses within the EP District pursuant to the intent statement for the District specified in ACC 18.33.010 (Intent). 2 During the Committee’s discussion of the potential draft amendments for ACC 18.33 at its rd March 23 meeting, staff would like to discuss the following questions: 1.What are the Committee’s viewpoints on the proposed revisions submitted by staff for this chapter? 2.Does the Committee want to attempt to achieve a maximum 75 percent maximum lot coverage standard through possible changes in the current parking standards? 3.Does the Committee have additional questions or information needs that it wants staff to research and report back on at a future meeting? D.PACC18.50(L&S)A ROPOSEDANDSCAPING CREENINGMENDMENTS The following is a summary of key potential code amendments for this chapter developed by rd staff subsequent to the Committee’s February 23 meeting. In addition, key questions that staff would like to discuss with the Committee are presented: Potential amendment to ACC 18.50.050.I.1 to provide the planning director or designee with the authority to modify the requirement for Type III landscaping in all required yards to support innovative site design features. Potential amendment to ACC 18.50.050.I.2 to provide the planning director or designee with the authority to reduce the width of required landscaping by additional methods beyond those currently listed in the code to support innovative site design features. Potential amendment to ACC 18.50.050.I.3 to reduce the current percentage of the site to be landscaped from 15 percent to 10 percent. Staff’s analysis of the application of increased maximum lot coverage percentages indicates that this reduction would be needed for some of the existing parcels within the EP District to achieve the proposed 50 percent maximum lot coverage standard and for all parcels to achieve any authorized increase in maximum lot coverage over 50 percent. Potential amendment to ACC 18.50.060.E to allow the use of sodded lawns in the EP District only when the irrigation source is recycled on-site water to promote a higher level of on-site water conservation. Potential amendment to ACC 18.50.060.H.1-4 to provide the planning director or designee with the authority to modify current design standards for parking lots to support innovative site design features. During the Committee’s discussion of the potential draft amendments for ACC 18.50 at its rd March 23 meeting, staff would like to discuss the following questions: 1.What are the Committee’s viewpoints on the proposed revisions submitted by staff for this chapter? 3 2.Does the Committee concur with staff’s recommendation to provide the planning director with the authority to modify landscaping requirements for the EP District only to support innovative site design features? 3.Does the Committee have additional questions or information needs that it wants staff to research and report back on at a future meeting? E.PACC18.52(O-SPL)A ROPOSEDFFTREET ARKING AND OADINGMENDMENTS The following is a summary of key potential code amendments for this chapter developed by rd staff subsequent to the Committee’s February 23 meeting. In addition, key questions that staff would like to discuss with the Committee are presented: Potential amendment to ACC 18.52.010.B.3-4 to exclude the EP District only from requirements that might lead to the expansion of existing parking areas or the development of new parking areas that could result in the creation of additional impervious surfaces. Potential amendment to the table at the beginning of ACC 18.52.030 to provide for the opportunity to reduce the amount of required parking in the EP District to promote less impervious surfaces and associated stormwater impacts. Potential amendment to ACC 18.52.030.B to provide the planning director or designee with the authority to approve joint use parking facilities having the same peak parking demands when both on-site parking and the availability to multi-modal transportation options such as transit shuttles, bicycle facilities, carpool programs or vanpool programs. Potential amendment to ACC 18.52.050 implementing a new requirement for the use of pervious pavement materials in the EP District only unless it can be demonstrated to the planning director and the city engineer that the use of these materials is impracticable due to soil conditions or cannot support the post development traffic loads of a project. The purpose of this proposed amendment would be to substantively reduce the future introduction of new impervious surfaces into the EP District. Potential amendment to ACC 18.52.090.B to specify for the EP District only that up to 100 percent of the parking spaces for a development may be constructed as compact parking spaces to contribute to a reduction in the overall size of on-site parking areas. Potential amendment to ACC 18.52.090.E to exclude parking areas in the EP District from the current overhang provisions of the code to promote more innovate site design features (e.g. in-parking area bio-swale) and allow for overhang landscape areas to be counted toward meeting the on-site landscaping requirement to promote more alternatives for addressing site specific building coverage, on-site parking and landscaping issues. Potential amendment to ACC 18.52.130 to allow for the development of joint off-street loading facilities between multiple uses to help reduce the area of impervious surfaces. 4 During the Committee’s discussion of the potential draft amendments for ACC 18.52 at its rd March 23 meeting, staff would like to discuss the following questions: 1.What are the Committee’s viewpoints on the proposed revisions submitted by staff for this chapter? 2.Does the Committee want to consider further reduction of the on-site parking standards (i.e. significant reduction in the on-site parking requirements or the promotion of one or two shared parking facilities in the District for all businesses rather than individual site development of parking facilities) to further promote the environmental friendly intent of the EP District? 3.Does the Committee have additional questions or information needs that it wants staff to research and report back on at a future meeting? F.IALEEDPC NFORMATION ON DVANTAGES OF LATINUM ERTIFICATION rd At the February 23 meeting, the Committee asked to report back on the advantages of LEED Platinum certification as part of its consideration of using the LEED Silver certification. Staff has researched this question and finds that the answer is complicated because of the multiple methods that can be used to achieve this rating and the associated potential benefits of these different methods. However, staff’s review of the current information on the LEED Platinum rating from the US Green Building Council – the creator and operator of the LEED certification system - have identified some potential advantages: Marketing and public relations – The receipt of the LEED Platinum rating for a building or a project is viewed as a potential marketing tool for future building users and a positive public relations image message. Rebate on Certification Fees – The US Green Building Council currently offers a full rebate on all certification fees it charges for projects that attain a LEED Platinum certification. Lower long-term operating costs – LEED platinum buildings require the implementation of conservation oriented business practices and the installation of materials and equipment that 3 are energy and resource efficient that can lead to lower long-term operating costs. 3 In a January 8, 2009 press release from the US Green Building Council, the Council reported that in 2003, California's Sustainable Building Task Force reported on the costs associated with its green buildings. That report found the cost premium averaged less than 1 percent for basic LEED certification, 2.1 percent for Silver certification, 1.8 percent for Gold, and 6.5 percent for Platinum. The Council further reported that in a separate 2008 report, which included contributors from Boston College, The Brookings Institution, and PNC Financial Services group, researchers found that green buildings cost less than 4 percent more than conventional buildings, with the highest premium concentrations being no more than 1 percent. The Council reported that the California EPA Headquarters Building in Sacramento, CA attained a Platinum LEED for Existing Buildings in 2004. The Council stated in the January 8, 2009 press release that with systems calibration, monitoring, and maintenance for energy performance, the building delivers annual savings of nearly $200,000 and that after-hours heating and lighting controls as well as the building's exterior lighting systems add another $110,000 of yearly savings. The Council 5 Positive contribution to climate change – LEED platinum buildings can substantially reduce the emission of carbon dioxide (CO2) into the atmosphere. rd During the Committee’s discussion at its March 23 meeting, staff would like to discuss the following questions: 1.Does the Committee have additional questions or information needs that it wants staff to research and report back on at its next meeting pertaining to LEED Platinum or other certifications? further reported that $500,000 was invested in efficiency upgrades, operations, and employee practices, which generated a total of $610,000 in annual savings and that this initial investment was recovered in less than a year. The Council’s press release also stated that according to the building's USGBC project profile, using an 8 percent capitalization rate, the annual cost savings have increased the asset value of the building by nearly $12 million. 6 DRAFT FOR REVIEW ONLY – SUBJECT TO CHANGE 18.33.040 Development standards.

Every parcel of land hereafter used as a public or private off-street parking area shall be developed and maintained as follows: A. The parking areas on private property, including interior driveways and access to a public street, shall be paved with asphalt concrete or cement concrete pavement and shall have appropriate bumper guards where needed. Where a driveway crosses an improved public right-of-way, it shall be constructed with cement concrete. All pavement sections shall be designed to support the post development traffic loads anticipated due to the intended use as approved by the city engineer. B. Parking areas inclusive of parking spaces, drive aisles and pedestrian crossings in the EP District shall be constructed with pervious pavement composed of concrete or asphalt or pavers or grid systems filled with grass or gravel or other low impact development methods proposed by the applicant and determined to be appropriate to the site and type of development. The planning director or designee and the city engineer may allow impervious pavement only after evidence that the use of pervious pavement or other similar materials would be impractical due to soil conditions or cannot support the post development traffic loads anticipated due to the intended use. In order to make this determination, the planning director or designee and the city engineer will review written and plan documentation submitted by the applicant’s engineer, architect or contractor and make findings therein. In making their findings, the planning director or designee and the city engineer shall in any approval of pervious paving materials consider the public health, safety and welfare. 18.52.090 Parking space dimensional requirements. B. Compact Sized Parking Spaces. 1. In any off-street parking lot up to 30 percent of the spaces may be designated as “compact” spaces and be developed according to the minimum dimensional requirements for compact spaces established under this section. Municipally owned/leased automobile parking facilities may designate up to 50 percent of the spaces as “compact.” 2. To promote low impact development and reduce stormwater runoff impacts, up to 100 percent of the parking spaces for development in the EP District may be developed according to the minimum dimensional requirements for compact spaces established under this section. E. Overhang parking may be permitted. 1. The overhang area need not be paved but must be landscaped with deciduous trees planted 30 feet on center and groundcover or sodded lawn provided. The trees shall be planted to avoid conflict with the vehicles. No overhang landscape areas, created exclusively for overhang parking, shall be considered to meet the landscape requirements of this title. The overhang landscape area must be a minimum width of five feet; however, the maximum overhang allowed into the landscaped area shall be two feet.
