    Aaron Sage, AICP | Senior Planner | City of Berkeley Planning and Development Dept. | Land Use Planning Division 2120 Milvia Street | Berkeley, CA 94704

    Re: 2539 Telegraph

    Use Permit #2013-0061 Dear Aaron,

    Responses to the comments in your Incomplete Letter dated January 29, 2014 are provided below in red. The project application materials have been revised accordingly and resubmitted.

    • In addition to the permits paid for at application intake, the application also

    requires the following permits under the Zoning Ordinance, with a fee of $414 each. Please see attached invoice. These fees may be paid at the Permit Service Center (bring a copy of this letter to show the planner at the Zoning counter), by mailing a check (payable to “City of Berkeley”) to my attention, or by e-mailing a copy of the attached “Credit Card Authorization Form” to me.

    • Use Permit under BMC Section 23C.08.050.A to demolish a main building • Use Permit under BMC Section 23E.56.050.A.2 to create over 1,500 square

    feet of new floor area Invoice for $828 paid by Panoramic Interests on 3/5/14.

    • In order to project into required yard fronting on Regent Street, bay windows

    must meet the following definition:

    Bay Window : A portion of a building cantilevered so as to project out from a wall and containing windows which cover at least 50% of the projection’s surface. A bay window which projects into a required yard shall not exceed 25% of the length of the wall.

    Based on floor plans, the wall from which bay windows project is 64 feet long. Therefore, total width of the bays must not exceed 16 feet. Also, per BMC Section 23D.04.030.A, the maximum projection into the required yard is 2.5 feet. Please revise bay windows to comply with these limits. Because bays will be considerably smaller, it may be necessary to further articulate the main façade. The size of the bay windows has been reduced per the definition above in the base project plan and calculations. The larger bay windows are requested as a Concession as part of the project’s density bonus.

  • • Per BMC Section 23D.04.030.A, uncovered stairs may project a maximum of 6 feet into the required yard fronting on Regent Street (providing a minimum 9- foot setback). Please revise plans to comply. Also, please note that staff has concerns about the design of the stairwell and the degree to which it projects from the main façade. This issue should be discussed with Anne Burns, and we will be requesting input from the DRC on this. The rear exit stairs to Regent Street have been incorporated into the building massing and their projection into the setback has been reduced. The stairs project 5’-6” into the setback at the Regent Street level and only 3’-0” (the same as the bay windows) at every level above.

    • Please revise base project drawings and density bonus calculations as

    necessary to comply with the following issues: (1) The rear stairs and bay windows would not comply with the limits noted above; (2) Because the garage level counts as the first story for the R-3 portion of the building, only two levels of residential space within the R-3 District can be counted in the base project calculations; (3) The Fire Department requires bedroom windows to be set back more than 3 feet from side property lines in order to provide adequate ladder access; I am waiting for verification of the minimum setback and will provide this as soon as possible.

    The base project drawings have been revised per Items #1 & 2. No action taken on Item #3. Per Fire Department direction at Interdepartmental Review Meeting on 2/12/14, ladder access is not required for bedroom windows due to proposed building’s Type III Construction.

    • As discussed earlier with the project developer, the change in the building’s

    massing scheme from a base project with minimal side setbacks to the proposed project with greater setbacks and greater height than would otherwise be necessary, may only be approved by concession. The density bonus calculations and the applicant statement should be revised to state that the fifth story is requested as a “waiver/reduction” (not a concession), and the sixth story and modified massing scheme are requested as concessions. Density Bonus calculations and applicant statement have been revised per the above direction.

    • Based on the previous comment, please submit a “pro forma” showing the

    return on investment in each of the following four scenarios: (1) base project without affordable units and with housing impact fee, (2) base project with affordable units, (3) density bonus project without concessions, (4) proposed project. A fee may be required for peer review of this document by a qualified third-party consultant. A pro-forma is provided with this application.

  • • Street trees will be required for this project and must be shown on the drawings, after City Forester has provided required species, sizes and locations. Please work with Anne Burns on this.

    Proposed street trees are depicted on the plans, per City Forester’s direction during the Interdepartmental Review Meeting on 2/12/14.

    • Please indicate number of bikes that can be parked in bike storage room.

    Please consider use of dual-level racks to increase potential storage. Proposed Response: 54 single wall mounted bike racks can be accommodated in the bike storage room for residential use. 10 sidewalk bike racks are provided for commercial use.

    • Please provide two additional 11” x 17” reduced plan sets, and one “full-size”

    set printed to scale. Please ensure that photos print clearly – the set I reviewed had some kind of “fuzz” on several of the photos.

    The requested plan sets, with improved resolution, are included in the revised application materials.

    • Per Item III.A.4 of the “Zoning Project Submittal Requirements,” at least four

    photo simulations of the project are required. For more accurate representation of the project’s context, please provide simulations based on actual photos, rather than a computer model of the surrounding area. Two of the required four simulations should be on the Regent Street side, one from the north and one from the south. If major revisions to the project are contemplated (for example, to address comments in this letter or from the DRC), you may wait until after these revisions are made to prepare these simulations.

    Major revisions to the project’s façade design are being contemplated. The simulations will be provided at a later date once these revisions are complete.

    • Per our shadow study guidelines, please provide existing shadow drawings as

    well as proposed, so we can evaluate the increase in shading.

    Shadow Studies of existing conditions are included in revised application.

    • Please note that additional information regarding the history of the existing building will be required as part of the EIR process. In addition, other technical reports, such as a traffic impact analysis and an evaluation of risks associated with excavation adjacent to the former dry cleaning site, may also be required during the EIR process. Noted.

  • • Please note that parklets are currently only allowed subject to a limited pilot program. Please contact Diana Aikenhead at 510-981-7448 or daikenhead@cityof berkeley.info for further discussion as to whether your proposed parklet would qualify for this program. The applicant has contacted Diana Aikenhead for direction on parklets. Based on comments from Diana and Michael Vecchio (Traffic Engineer) the project now proposes a formal bulbout at this location rather than a parklet.

    • Please note that the City’s traffic engineer is currently reviewing the proposed

    parking garage and loading zone and will provide comments at a future date.

    Noted. Comments from the Traffic Engineer and other departments given during the Interdepartmental Review Meeting on 2/12/14 have been incorporated into the garage and loading design.

    Sincerely,

    Daniel Backman, Lowney Architecture

    mailto:[email protected]

  • 2539 Telegraph Avenue March 28, 2014 Mixed-Use Development Applicant Statement Applicant: Daniel Backman, Lowney Architecture 360 17th Street, Suite 100 Oakland, CA 94612 On behalf of: Panoramic Interests 2116 Allston Way, Suite 1 Berkeley, CA 94704 The proposed project is a 6-story mixed-use residential and retail development. There will be a retail storefront along the majority of the Telegraph Avenue frontage. A driveway at the south end of the site will provide access to an enclosed parking garage with 8 parking spaces, as well as the building’s trash and recycling receptacles. The residential lobby is located at the northwest corner of site, along with a leasing office for the project. Additionally, the ground floor houses a bike storage room for residents, and the building’s utility room.

    Above the podium there will be 5 levels of housing, with 13 units per floor for a total of 65 units. Typical units will have 2 bedrooms, 1 bathroom, a living room, a dining nook and a kitchenette. Each residential level will include community room with shared laundry facilities. The residential levels are arranged in a “T” shape with 4 irregular shaped units facing Telegraph and 9 similarly sized units facing north and south along a corridor leading the rear exit stair.

    The exterior areas on top of the podium will not be occupied spaces, but will provide a setback from the side property lines along the back half of the site. Planters will be provided along the edge of the podium to screen the units from the neighboring properties. The roof deck, accessed by elevator and both stairways, will provide open space for residents. The rooftop open space will include a variety of seating, shading, planting and other amenities, along with sweeping views of the bay. At the rear of the site along Regent Street, the building is set back 15’ from the property line per R-3 Zoning. The garage below and the levels above have their secondary exit through this area. Otherwise this area will be set aside for landscaping with biofiltration zones which will meet the C-3 requirements for the project. As a result, the existing “pocket park” in that location is largely preserved. The proposed project is a Density Bonus project. Through the provision of 11% Affordable Units at 50% AMI, the project merits a 35% Density Bonus. The proposed project requests a waiver/reduction from Zoning to increase the story and height limit from 4 stories and 50’ to 5 stories and 65’ tall. Additionally the proposed project requests the following concessions from Zoning. These concessions are requested because the allowable Density Bonus units cannot be adequately accommodated within the height limit per current zoning.

    A. Increased building height from 5 stories & 65' to 6 stories & 70' within C-T zone B. Increased height from 3 stories & 35' to 6 stories & 70' within R3 Zone C. Waiver of side setback for ground level where site is adjacent to R-3 Zone D. Allow for larger bay window projections into Regent Street setback

    The applicant believes that the building massing and the quality of the units will be significantly enhanced and that the impact on the project’s neighbors will be reduced by allowing for increased building height at this site.

    If "INFEASIBLE" is checked for Item 6.1, then the applicant may use appropriately designed bioretention * ,1 facilities for compliance with C.3 treatment requirements. If Ksat > 1.6 in./hr., and infiltration is unimpeded by subsurface conditions, then the bioretention facilities are predicted to infiltrate 80% or more average annual runoff. If Ksat < 1.6, maximize infiltration of stormwater by using bioretention if site conditions allow, and remaining runoff will be discharged to storm drains via facility underdrains. If site conditions preclude infiltration, a lined bioretention area or flow-through planter may be used.

    Does the location of utilities, a septic system and/or heritage trees* limit the placement of a cistern on the site to the extent that rainwater harvesting is infeasible? (If so, attach an explanation.)

    6. Results of Feasibility Determination

    Are there geotechnical/stability concerns related to the surface (roof or ground) where a cistern would be located that make the use of rainwater harvesting infeasible? (If so, attach an explanation.)

    Do constraints, such as a slope above 10% or lack of available space at the site, make it infeasible to locate on the site a cistern of adequate size to harvest and use the C.3.d amount of water? (If so, attach an explanation.)

    Would the technical requirements cause the harvesting system to exceed 2% of the Total Project Cost*, or has the applicant documented economic hardship in relation to maintenance costs? (If so, attach an explanation.)

    If "FEASIBLE" is indicated for Item 6.1 the amount of stormwater requiring treatment must be treated with harvesting/use, unless it is infiltrated into the soil.

    Check “Yes” or “No” to indicate whether the following conditions apply. If “Yes” is checked for any question, then rainwater harvesting and use is infeasible. As soon as you answer "Yes", you can skip to Item 6.1. If “No” is checked for all items, then rainwater harvesting and use is feasible and you must harvest and use the C.3.d amount of stormwater, unless you infiltrate the C.3.d amount of stormwater*.

    Refer to the applicable countywide table in Attachment 2. Identify the number of dwelling units per impervious acre needed in your Rain Gauge Area to provide the toilet flushing demand required for rainwater harvest feasibility.

    Refer to the applicable countywide table in Attachment 2. Identify the square feet of non-residential interior floor area per impervious acre needed in your Rain Gauge Area to provide the toilet flushing demand required for rainwater harvest feasibility.

    Is the project's square footage of non-residential interior floor area per acre of potential rainwater capture area (listed in Item 4.2) LESS than the number identified in Item 4.4?

    Is the project's number of dwelling units per acre of potential rainwater capture area (listed in Item 4.1) LESS than the number identified in Item 4.3?

    Based on the results of the feasibility analysis in Item 4.4 and Section 5, rainwater harvesting/use is (check one):

    Note: It is assumed that projects with significant amounts of landscaping will either treat runoff with landscape dispersal (self-treating and self-retaining areas) or will evaluate the feasibility of havesting and using rainwater for irrigation using the curves in Appendix F of the LID Feasibility Report.

    5. Determine feasibility of rainwater harvesting and use based on factors other than demand.

    Does the requirement for rainwater harvesting and use at the project conflict with local, state, or federal ordinances or building codes?

    I.B.6 Does the total amount of Replaced impervious surface equal 50 percent or more of the Pre-Project Impervious Surface? If YES, stormwater treatment requirements apply to the whole site; if NO, these requirements apply only to the impervious surface created and/or replaced.

    I.C. Projects that are NOT C.3 Regulated Projects

    If you answered NO to Item I.B.5, or the project creates/replaces less than 5,000 sq. ft. of impervious surface, then the project is NOT a C.3 Regulated Project, and stormwater treatment is not required, BUT the municipality may determine that source controls and site design measures are required. Skip to Section II.

    I.D. Projects that ARE C.3 Regulated Projects

    If you answered YES to Item I.B.5, then the project is a C.3 Regulated Project. The project must include appropriate site design measures and source controls AND hydraulically-sized stormwater treatment measures. Hydromodification management may also be required; refer to Section II to make this determination. If final discretionary approval was granted on or after DECEMBER 1, 2011, Low Impact Development (LID) requirements apply, except for “Special Projects.” See Section II.

    I.E. Identify C.6 Construction-Phase Stormwater Requirements

    Yes No

    I.E.1 Does the project disturb 1.0 acre (43,560 sq.ft.) or more of land? (See Item I.A.10). If Yes, obtain coverage under the state’s Construction General Permit at https://smarts.waterboards.ca.gov/smarts/faces/SwSmartsLogin.jsp. Submit to the municipality a copy of your Notice of Intent and Storm Water Pollution Prevention Plan (SWPPP) before a grading or building permit is issued.

    I.E.2 Is the site a “High Priority Site” that disturbs less than 1.0 acre (43,560 sq.ft.) of land? (Municipal staff will make this determination.)

    “High Priority Sites” are sites that require a grading permit, are adjacent to a creek, or are otherwise high priority for stormwater protection during construction (see MRP Provision C.6.e.ii(2))

    NOTE TO APPLICANT: All projects require appropriate stormwater best management practices (BMPs) during construction. Refer to the Section II to identify appropriate construction BMPs.

    II.D. Implement construction Best Management Practices (BMPs) (Applies to all projects).

    PROJECTS THAT ARE NOT C.3 REGULATED PROJECTS STOP HERE!

    II.E. Feasibility/Infeasibility of Infiltration and Rainwater Harvesting/Use (Applies to C.3 Regulated Projects ONLY)

    Except for some Special Projects, C.3 Regulated Projects must include low impact development (LID) treatment measures. LID treatment measures are rainwater harvesting, infiltration, evapotranspiration, and biotreatment (landscape-based treatment with special soils). Biotreatment is allowed ONLY if it is infeasible to treat the amount of runoff specified in Provision C.3.d with rainwater harvesting, infiltration, and evapotranspiration.

    Yes No N/A

    II.E.1 Is this project a “Special Project”? (See Appendix K of the C.3 Technical Guidance for

    criteria.)

    If No, continue to Item II.E.2.

    If Yes, or if there is potential that the project MAY be a Special Project, complete the Special Projects Worksheet.

    II.E.2 Infiltration Potential. Based on site-specific soil report11

    , do site soils either:

    a. Have a saturated hydraulic conductivity (Ksat) less than 1.6 inches/hour), or, if the Ksat rate is not available,

    b. Consist of Type C or D soils?

    If Yes, infiltration of the C.3.d amount of runoff is infeasible. Continue to II.E.3.

    If No, complete the Infiltration Feasibility Worksheet. If infiltration of the C.3.d amount of runoff is found to be feasible, skip to II.E.8; if infiltration is found to be infeasible, continue to II.E.3.

    11 If no site-specific soil report is available, refer to soil hydraulic conductivity maps in C.3 Technical Guidance Appendix J.

    Yes No Best Management Practice (BMP)

    Attach the municipality’s construction BMP plan sheet to project plans and require contractor to implement the applicable BMPs on the plan sheet.

    Temporary erosion controls to stabilize all denuded areas until permanent erosion controls are established.

    Delineate with field markers clearing limits, easements, setbacks, sensitive or critical areas, buffer zones, trees, and drainage courses.

    Provide notes, specifications, or attachments describing the following: Construction, operation and maintenance of erosion and sediment controls, include inspection frequency; Methods and schedule for grading, excavation, filling, clearing of vegetation, and storage and disposal of

    excavated or cleared material; Specifications for vegetative cover & mulch, include methods and schedules for planting and fertilization; Provisions for temporary and/or permanent irrigation.

    Perform clearing and earth moving activities only during dry weather.

    Use sediment controls or filtration to remove sediment when dewatering and obtain all necessary permits.

    Protect all storm drain inlets in vicinity of site using sediment controls such as berms, fiber rolls, or filters.

    Trap sediment on-site, using BMPs such as sediment basins or traps, earthen dikes or berms, silt fences, check dams, soil blankets or mats, covers for soil stock piles, etc.

    Divert on-site runoff around exposed areas; divert off-site runoff around the site (e.g., swales and dikes).

    Protect adjacent properties and undisturbed areas from construction impacts using vegetative buffer strips, sediment barriers or filters, dikes, mulching, or other measures as appropriate.

    Limit construction access routes and stabilize designated access points.

    No cleaning, fueling, or maintaining vehicles on-site, except in a designated area where washwater is contained and treated.

    Store, handle, and dispose of construction materials/wastes properly to prevent contact with stormwater.

    Contractor shall train and provide instruction to all employees/subcontractors re: construction BMPs.

    Control and prevent the discharge of all potential pollutants, including pavement cutting wastes, paints, concrete, petroleum products, chemicals, washwater or sediments, rinse water from architectural copper, and non-stormwater discharges to storm drains and watercourses.

    6 FINALSeptember 28, 2012

    II.E.3

    Recycled Water. Check the box if the project is installing and using a recycled water plumbing system for non-potable

    water use.

    The project is installing a recycled water plumbing system, and the installation of a second non-potable water system for harvested rainwater is impractical, and considered infeasible due to cost considerations.

    If you checked this box, there is no need for further evaluation of rainwater harvesting. Skip to II.E.9.

    II.E.4 Potential Rainwater Capture Area

    a. Refer to the Table of Impervious and Pervious Surfaces in Section I, and enter the total square footage of impervious surface that will be replaced and/or created by the project.

    Sq. ft.

    b. If I.B.6 indicates that 50% or more of the existing impervious surface will be replaced with new impervious surface, then add any existing impervious surface that will remain in place to the amount in II.E.4.a.

    Sq. ft.

    c. Convert the amount in Item II.E.4.b from square feet to acres (divide by 43,560). If

    II.E.4.b is not applicable, convert the amount in II.E.4.a from square feet to acres. This is the project’s Potential Rainwater Capture Area, in acres.

    Acres

    II.E.5 Landscape Irrigation: Feasibility of Rainwater Harvesting and Use

    a. Enter area of onsite landscaping.

    Acres

    b. Multiply the Potential Rainwater Capture Area (the amount in II.E.4.c) times 2.5. Acres

    c. Is the amount in II.E.5.a (onsite landscaping) LESS than 2.5 times the size of the amount in II.E.5.b (the product of 2.5 times the size of the Potential Rainwater Capture Area)

    12?

    If Yes, irrigation use of the C.3.d amount of runoff is infeasible. Continue to II.E.6.

    If No, it may be possible to meet the treatment requirements by directing runoff from impervious areas to self-retaining areas (see Section 4.2 of the C.3 Technical Guidance). If not, refer to Table 11 and the curves in Appendix F of the LID Feasibility Report to evaluate feasibility of harvesting and using the C.3.d amount of runoff for irrigation. If that analysis shows that it is feasible to harvest and use the C.3.d amount of runoff, complete Part 5 (Factors Other than Demand) of the Rainwater Harvesting/Use Feasibility Worksheet. Skip to II.E.7.
