The attached comments are based upon the submitted Concept Plan, received February 18, 2014. We understand that this project has already received a lot of review and input from City staff through more informal discussions and meetings prior to and during the Concept review. The attached comments acknowledge these discussions as well as address the more technical issues that are typically associated with a Concept review. The next step will be a second Stage I Concept Plan, based on the Concept checklist and attached comments. Prior to preparing the Concept I submission, staff recommends meeting with Development and Historic Preservation staff to discuss the proposed site layout and compliance with the Waterfront Plan. With the next submission, please include a response letter addressing the comments below, a completed checklist, all materials identified in the checklist and all information requested by staff with the next submission. In the event you have any questions, or desire a meeting to discuss the comments, please feel free to contact me at 703-746-3815 or at [email protected]. Sincerely, Dirk H. Geratz, AICP Principal Planner, Development Division cc: Rob Kerns, Division Chief, Development, P&Z Jessica McVary, Urban Planner, Development, P&Z Shanna Austin, Site Plan Coordinator, T&ES Call: 703.746.4666 Connect: www.alexandriava.gov Come by: 301 King Street, Room 2100 Alexandria, VA 22314 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 Please respond in writing to the following comments: PLANNING AND ZONING During this review, Planning Staff made an effort to identify what we believe to be key issues associated with the redevelopment of Robinson Terminal South. These issues have been grouped into five broad categories and include comments related to the environment, creation of active amenity spaces / uses, site planning, building design and issues related to site history and historic preservation. Comments related to each of these categories are provided below along with our general comments. Applications 1. Please note that the following applications will be required for this project as currently proposed: a. A development special use permit with site plan to increase the FAR above 2.0 per section 5-504(D); b. A special use permit for a public or private marina per section 5-503(C); c. A special use permit for a restaurant per section 5-503(C); d. A special use permit for a retail shopping establishment per section 5-503(C); e. A special use permit to increase the height from 30 feet to 50 feet pursuant to section 6-404(B) f. A parking reduction special use permit; g. A transportation management plan; and h. Board of Architectural Review Permit to Demolish and Certificate of Appropriateness. Environment 2. Extensive land disturbing activities are anticipated with this proposal that pose potential harm to the environment. As such staff recommends developing a comprehensive environmental strategy that should at a minimum include the following: a. Develop an approach to meeting the FEMA requirements with regard to elevating the grade of the site out of the floodplain. b. Develop an approach to protecting the Potomac River from run-off during the grading and re-grading of the site. c. Develop an approach for the transportation of fill and the removal of contaminated soils. Staff anticipates that the transportation of soil may need to be done from the waterside via the use of barges. Please provide a narrative description of the above requested strategies with the next submission. 2 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 Active Amenity Space / Uses 3. Creation of an active waterfront is a primary goal of the Waterfront Plan. Staff recommends the following: a. Develop a vision for the creation of active public space and amenities on the waterfront boardwalk and pier. Submit materials to support this vision, which could include a narrative and additional precedent images with greater detail focused on how the waterfront will be activated. b. Develop a retail strategy to establish vibrant retail / restaurant uses along The Strand and the Waterfront. Provide details on the proposed retail strategy with the next submission and identify a retail consultant with experience in waterfront retail / entertainment development as part of your team. 4. The Waterfront Plan includes specific development guidelines for Robinson Terminal South. Staff recommends the following refinements to improve consistency with the Plan’s development guidelines. a. Staff acknowledges that the hotel use will no longer be a component of Robinson Terminal South and understands that this changes the anticipated dynamics of the land uses. However, this provides an opportunity to identify other uses and activities to meet the goals of the plan. As such, revise the site design to increase the amount of active retail / commercial frontage, in accordance with Development Guideline #1 and Figure 34. b. Expand the “active uses” along Buildings 1 and 2 to better activate the pier. At a minimum, active uses should be the primary use for the ground level of buildings east of The Strand and 2 Duke Street. Similarly, the Plan’s restriction on ground floor residential units should be respected, at a minimum, for buildings which front the Potomac River and public parks. c. Examples of uses that may be appropriate on the first floor in addition to the restaurant may include a pub or café, gallery, small office space and community room. d. Provide additional information on the unit types proposed to clarify how the proposed residential use and design are compatible with a high-level of public activity, particularly those proposed to front on the activated spaces. e. Revise the design to provide all parking below grade as required by the Waterfront Plan. Doing so provides a number of significant advantages for both the City and the applicant (including future residents and owners), specifically: i. Increases the amount of ground-level open space; ii. Eliminates unattractive alley views; iii. Introduces a rear garden at the ground floor of townhouse units, which is the predominant typology in historic residential buildings in the adjoining historic district; and iv. Allows for a more traditional townhouse configuration with the primary living space located on the first floor, at street level, as opposed to devoting half or more of the ground floor to garage space. 3 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 f. Provide additional information on the proposed renovation of the existing pier for public use, as noted in the Site Development Narrative on sheet 2. The Plan “recommends that connections be provided at both the northern and southern ends of the pier, and improvements made to ensure the safety of users.” These additional pedestrian connections were specified in Development Goal #4, and were placed to achieve two important plan goals: 1) offer a choice between a land-side and water-side experience for people walking along the Waterfront, and 2) encourage a higher volume of pedestrian activity on the pier to activate the water-side uses envisioned by the Plan. The Plan also provides examples of potential uses on the pier area. 5. Buildings 1, 2 and 3 shall also include primary entrances along the Waterfront and Wolfe Street, respectively, to activate these frontages. Site Plan 6. Continue The Strand further south to create an enhanced east-west alignment between Waterford Place and the existing pier. This relocation of The Strand also offers an opportunity to increase the active frontages, as it allows a larger building footprint (lined with active uses) to the north and a smaller, less active building footprint to the south. This can be accomplished without changing the number or sizes of any building footprints, as shown in Attachments 1 and 2. Please see these diagrams for clarification. 7. Continue to work with staff on the extension of The Strand into the site. For example, the material, paving patterns and width of The Strand extension should be consistent with the design of The Strand north of the site. 8. Locate townhouse residences along the public street edges (Union and Wolfe). 9. Locate the small multi-family building towards the center of the block with frontage on Union Street. Alternatively, locate the multi-family building at the corner of Union and Duke Streets to create a transition from the scale of the approved hotel and the subject property. 10. The site is overwhelmingly covered in hard surfaces. Staff recommends the provision of more green open space and a reduction in impervious surface areas. With underground parking, the alley ways between the townhouses can become small back yards in keeping with the historic pattern of small rear yards found throughout Old Town. 11. In consultation with City staff, establish appropriate sidewalk conditions to ensure adequate space for a standard sidewalk and street trees along the adjoining public street frontages. 4 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 12. The Waterfront Plan recommends the creation of “a continuous waterfront public space of at least 50 feet and preferably 100 feet or more to comply to the greatest degree possible with Chesapeake Bay Preservation Act guidelines and to better achieve the goals of the Eco-City Charter. There shall be a continuous waterfront walkway with a minimum width of 25 feet or wider, where appropriate.” (Page 35) Confirm that the walkway adjacent to the Waterfront is a minimum of 25 feet in width. Likewise, confirm that the publicly accessible space adjacent to the waterfront is a minimum of 50 feet in width. 13. Explore strategies to establish a stronger relationship between Roberdeau Park (located at the end of Wolfe Street) and the waterfront open space associated with the Harborside community. Building Design 14. This particular block is bounded by the Potomac River to the east, a proposed new hotel at 220 South Union Street to the north, the Waterford development to the west, and the Harborside development to the south. The BAR’s Guidelines discourage any mews-type developments and building entrances should be located on all public streets. Buildings should have little or no setback and new buildings should reflect the traditional pattern of spacing along the waterfront to maintain a consistent rhythm. Staff generally supports a range of building sizes and architectural expressions on the site as long as they have an appropriate quality of materials and architectural detail. As the project is comprised of a full block, each block face must relate to the character of the historic waterfront (waterfront, park, townhouses) with respect to architectural design, height, scale and mass. 15. The project must be in conformance with the BAR’s Standards and Additional Standards-Potomac River Vicinity outlined in Chapter 10 of the zoning ordinance. The applicant should reference the BAR’s adopted Design Guidelines for the waterfront in developing the design. The design should reflect the traditional waterfront building character, which was historically warehouse uses closest to the river, and should not be highly ornamented. Therefore, staff encourages an innovative architectural program that complements and is compatible with the overall character of the waterfront and historic district as a whole. Staff also reminds the applicant of the Plan’s encouragement to develop rooftop open spaces, as another way to maximize water views, while making a distinction between public and private uses (Development Goal #7). This goal can be combined with building setbacks at upper levels to also address issues of scale and specific BAR requirements. 16. The Waterfront Small Area Plan recommends that building and open spaces reflect Alexandria’s maritime history. Provide opportunities to recall and interpret the site’s history in the site and building designs. The Plan encourages modern architectural design inspired by historic precedent and should reflect the historic east-west orientation of buildings, alleys and wharves. The proposed alleys do not extend 5 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 through the entire block from east-west. Consider, for example, designing the residential condominium building and the townhouses on the western half of the property to read as small “warehouse” style buildings as opposed to appearing as individual townhouse units; this would better reflect the rhythm of varying footprints and heights along South Union Street which is established by the remaining, restored commercial and warehouse buildings to the north of this property. See Attachment 1 for how these issues could be addressed. 17. As noted earlier in the comments, Staff recommends that the townhouses take on a more historically accurate floor plan layout that relates more closely to the layout of historic homes whereby the main (active) living space is on the first floor as opposed to be elevated to the second floor and above the street level. Site History - Preservation 18. Develop a plan that addresses the history of the site and archaeology review. Explain how the history of the site can be used in the design of the site plan and / or the buildings. 19. The buildings on the project site include the following: a. 2 Duke Street: two-story brick commercial building (Built: Probably prior to 1877, with extensive repair work after 1897, and new north façade approved in 1989) b. 300 South Union Street: Metal warehouse built around portions of 2 Duke Street (Built: 1937-1939) c. 226 The Strand: Alexandria Marine Building (Built: Pre-1920, with some parts possibly pre-1877 d. Other building remnants possible as main site is an agglomeration of buildings 20. Historic maps show that the old Pioneer Mill, Bryant fertilizer warehouses and lumber piles were located on this block. 21. The subject property is located within the Old & Historic Alexandria District and any demolition or capsulation more than 25 square feet, alterations, signage, and new construction require approval by the Board of Architectural Review (BAR). The zoning ordinance requires the applicant to obtain a Permit to Demolish and a Certificate of Appropriateness from the BAR. A schedule of filing deadlines and fees can be found at http://www.alexandriava.gov/preservation. BAR Concept Review should be completed prior to submission of development Concept 2 plan. 22. In order to request a Permit to Demolish/Capsulate to demolish any buildings or any part of a building, the applicant will need to provide additional documentation, prepared by a Secretary of the Interior qualified architectural historian, regarding the history of the buildings and their current condition and integrity. Based on a site visit and very limited research, BAR staff finds that 2 Duke Street retains a high level of 6 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 integrity and should be retained and restored. While staff believes that 226 The Strand has been significantly altered, it is a historic building and additional research is necessary in order to make a final determination about whether all or portions of it retain historic integrity. 23. The Waterfront Small Area Plan notes that the southern point of the City’s original shoreline can be found on this property. As the concept plan is refined, please consider how the proposal will “recall or interpret the site’s history in the design and function of the project” – including the location of the original shoreline. General Comments 24. In future submission, please ensure consistent orientation on all plan sheets. 25. Pursuant to Table 2 on page 103 of the Waterfront Small Area Plan, the maximum permitted floor area permitted on the site is 380,529 sq. ft. (2.32 FAR). Please revise the site tabulations on sheet 3 of the submission accordingly and submit a more detailed zoning tabulation with the next submission. 26. Provide additional information related to the proposed uses. Specifically, identify the unit types proposed for the residential uses to determine the required parking. Likewise, estimate the number of seats anticipated in the proposed restaurant(s) and other non-residential uses to determine the required parking. 27. Confirm that the townhouses are proposed as “townhouse-style” condominiums, rather than fee-simple townhomes. Future Conditions 28. As noted in the Waterfront Small Area Plan, public art should be a prominent feature of the public realm, both on public and private property. The proposal is subject to compliance with the City’s Public Art Policy, and as noted in the Plan, “the recommendations of the Art Plan should be incorporated, to the greatest extent possible, in the design for the redeveloped warehouses, pier and public spaces.” Provide a comprehensive, project specific narrative describing how this project will address public art with the next submission. 29. Improvements to the pier shall be completed prior to the issuance of a certificate of occupancy for buildings which front the Waterfront. Please provide a phasing strategy with the next submission to demonstrate that this will be achieved. 30. The proposal shall comply with the City’s Green Building Policy. 31. All existing above grade utilities shall be located below grade. 7 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 32. The existing historic building at 2 Duke Street retains a high level of integrity and shall be retained and restored. Potential uses of the building should be identified and could include a restaurant or café on the first floor and gallery or office space on the second floor. 33. Public access shall be provided in several locations on the site, including along the Waterfront (Parcel H and the pier), The Strand (both the vehicular and pedestrian extensions) and other east-west connections on the site. 34. Pursuant to the Waterfront Plan, the applicant shall provide $20 per square foot in 2013 dollars in contributions. Dedications of land and improvements to the piers can be credited against the contribution, down to a floor of $9 per square foot in 2012 dollars. The $9 per square foot shall be dedicated to off-site public park development and improvements within the Waterfront Plan area. The $9 per square foot is in 2012 dollars and would be inflated to the year of construction. 35. The applicant will be required to participate in the long-term operations and maintenance of the Waterfront through a to-be determined management structure, such as a business improvement district. 36. A separate ownership regime shall be established for the commercial and residential components of the development. 37. Parcels E and M shall be dedicated to the City for public use. TRANSPORTATION AND ENVIRONMENTAL SERVICES Findings 38. A transportation study will be required for this site. (Transportation) 39. A parking study will be required to support any proposed parking reduction. (Transportation) 40. Transit has no comments on the Concept submission. 41. The applicant is reminded that unless a VSMP permit is issued prior to July 1, 2014 that the project will have to meet the new stormwater regulations. (OEQ) 42. The applicant is reminded of the restrictions associated with redeveloping in the RPA as indicated in Alexandria’s Environmental Management Ordinance section 13-107. (OEQ) 43. The applicant should be aware the parcel is immediately adjacent to a historic methane producing swamp area. (OEQ) 8 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 44. Green/sustainable measures should be planned for and incorporated during the conceptual design phase. Incorporating facilities such as rainwater harvesting, green roofs or flow through planter boxes into the building’s architecture will make it easier to meet the new stormwater regulations. (OEQ) Recommendations 45. According to Section 6-300 (FLOODPLAIN DISTRICT) of Article VI (SPECIAL AND OVERLAY ZONES) of the City of Alexandria Zoning Ordinance, Section 6305 - Administration, (C) No site plan, subdivision plat or building permit application which proposes to construct or make substantial improvements within any floodplain district shall be approved by any agency of the City of Alexandria without certification by the Director of Transportation and Environmental Services that the plan, plat or permit application meets the requirements of this Section 6-300. The Director of Transportation and Environmental Services shall insure that all other required permits related to development in the floodplain from state or federal governmental agencies have been obtained. Therefore, under this requirement the preliminary plan will not be certified to be compliant with section 6-300 for the following reasons: a. This proposed development is considered, in planning terms, a mixed-use development. Under the Floodplain Ordinance, this development does not meet the definition of a mixed-use development and must be regulated as a residential development. Section 6-306 (K). b. New residential developments in the floodplain are required to have the lowest floor, including basements (includes below ground parking) 1-foot above the Base Flood Elevation (BFE). Section 6-306 (A). The proposed development shows underground parking in the floodplain boundary; which is not compliant with the Floodplain Ordinance for residential structures. (Engineering) 46. If the development chooses to relocate the floodplain boundary by the application of fill material, the following section will apply: (Engineering) a. 6-307 Other Conditions. No filling of any kind shall be allowed within the boundaries of any A or AE Zone except where such filling, when considered in conjunction with all other uses, existing and proposed, will not increase the base flood elevation more than 0.5 foot [regulated to no rise]. Persons proposing such filling shall furnish specific engineering data and information as to the effect of their proposed action on future flood heights and shall obtain approval from the Director of Transportation and Environmental Services prior to any filling. 9 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 In order for the proposed development to be certified as compliant with the City’s Floodplain Ordinance, the applicant must provide the City with a FEMA Letter of Map Revision Based on Fill (LOMR-F) for the site, removing the floodplain boundary to within 20’ of any proposed residential building underground parking footprint. In addition, the applicant shall be required to demonstrate, using accepted engineering practices, that all structures are reasonably safe from flooding. An accepted method would be to demonstrate compliance with FEMA publication Technical Bulletin #10-01 by performing the Engineered Basement Option soils study and engineering analysis. Additional information may be required by the Director of Transportation and Environmental Services as authorized by Section 6-305 of the Floodplain Ordinance to ensure the development is reasonably safe from flooding. (Engineering) 47. Sheet 2; verify graphic depiction of floodplain. The base flood elevation is 10.2 within this section of the city. (Engineering) 48. Sheet 2; ensure all existing utilities are labeled and flow arrows provided as appropriate. (Engineering) 49. Provide an update on the status of the project’s Letter of Map Revision (LOMR) application. The required grading to remove the site from the flood plain shall be a part of the preliminary plan submittal. (Engineering) 50. The RPA line must be field verified. Contact OEQ at 703-746-4070 to schedule a field inspection. (OEQ) 51. Sheet 3 - The Strand should provide public access through the site. Provide more information with the next submission. (Transportation) 52. Sheet 3 – Additional streetscape area may be required along S. Union Street. The presently shown ~8 foot streetscape area on the east side of the street is likely not wide enough to support street trees as well as a sidewalk. (Transportation) 53. Sheets 2 & 3 – Show all existing crosswalks (missing 2nd crosswalk line on the east side of the Union & Wolfe intersection). (Transportation) 54. Sheet 6 – Show/identify a location for bicycle parking within the garage. (Transportation) 55. Sheet 6 – The proposed triple stacked commercial parking spaces will not be supported unless compelling additional information and justification on how they will be effectively utilized is provided. Provide additional information on how the commercial triple stacked and tandem parking spaces are proposed to be utilized with the next submission. (Transportation) 10 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 56. Sheet 6 – There are likely too many residential tandem spaces to be effectively utilized unless the plan is to have different condo owners or apartment units share tandem spaces. Staff has concerns that shared tandem spaces will not operate effectively in such a layout. Provide additional information on how these parking spaces are proposed to be utilized with the next submission. Explore limiting the number of tandem parking spaces and providing additional traditional parking spaces. Note that tandem parking spaces count as one parking space for zoning ordinance requirement purposes, and a parking reduction will be required if tandem spaces are to be considered as two parking spaces. (Transportation) Future conditions: 57. The applicant shall be aware that a major water quality impact assessment will be required for this project. (Engineering) 58. An enhanced two phase erosion and sediment control plan will be required given the close proximity of the project site to the river. (Engineering) 59. A detailed phasing plan will be required. The means of delivering and removal of fill and excavated material will need to be detailed in this plan and these methods will require approval by the Director of Transportation and Environmental Services. (Engineering) 60. A future condition will require a monetary contribution to Capital Bikeshare. (Transportation) 61. The applicant should be aware that a site characterization, risk assessment, management plan and health and safety plan will be required to be submitted to the City during final site plan process for review and approval. (OEQ) AlexRenew Comments: 62. Drawings shall include sanitary flow computations and complete layout of proposed sanitary mains. Please provide computations and proposed sanitary layout. 63. Proposed construction & discharge limits from the new facility could be regulated by ASA Pretreatment. Engineer/Owner is required to contact Alexandria Renew Enterprises (AlexRenew) Quality Manager, (703) 549-3382 ex: 2106. 64. Future Condition: Ensure all discharges are in accordance with City of Alexandria Code 4035. 65.

Future Condition: The Applicant shall coordinate with City of Alexandria T&ES to ensure to AlexRenew in writing that proposed additional flow does not exceed capacity in AlexRenew Potomac Interceptor (located in S. Union St.) during wet & average flow conditions. Written notice shall be provided from City that flow capacities to AlexRenew Interceptors & Trunk Sewers from proposed development will not exceed City’s wet & average allocated flow. VAWC Comments: 67. VAWC has no comments at this time. The attached water map is provided for reference. RECREATION PARKS AND CULTURAL ACTIVITIES 68. If any public park, open space or ROW is within the limits of work, then during construction, the applicant shall be responsible for all grounds maintenance within the limits of work. Upon completion of work, the Applicant shall restore impacted areas to the satisfaction of the City. Restoration shall include remedy of compacted soil, turf management, vegetation, irrigation, lighting and other site conditions. 69. Architectural finishes of buildings and structures adjacent to any public park, open space or ROW must present a public face. 70. Proposed landscape changes to public park, open space or ROW will be subject to City of Alexandria Landscape Guidelines including arboricultural review of existing vegetation. HOUSING 71. The applicant should be aware that the City’s Affordable Housing Contribution Work Group (AHCWG) recommended new voluntary contribution rates in October 2013. City Council received the AHCWG report in December of 2013. The voluntary contribution formula rates for 2014 are provided in the table below.

Work must cease in the area of the discovery until a City archaeologist comes to the site and records the finds. The language noted above shall be included on all final site plan sheets involving any ground disturbing activities. (Archaeology) 77. The applicant shall not allow any metal detection and/or artifact collection to be conducted on the property, unless authorized by Alexandria Archaeology. Failure to comply shall result in project delays. The language noted above shall be included on all final site plan sheets involving any ground disturbing activities. (Archaeology) 13 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 78. Certificates of Occupancy shall not be issued for this property until interpretive elements have been constructed, interpretive markers have been erected, and the final archaeological report has been received and approved by the City Archaeologist.*** (Archaeology) Archaeology Findings The subject property is situated at one of Alexandria’s most historic places, Point Lumley, named for a ship’s captain who frequented the area. When the City of Alexandria was formally established in 1749, Point Lumley formed the south end of the surveyed town. By 1752 Thomas Fleming established the city’s first shipyard at Point Lumley, and the property continued from that point forward to be closely associated with shipbuilding, shipping, and other water-related industries. Fleming’s shipbuilding business flourished throughout the 1760s, but began to decline by the early 1770s, perhaps due in part to a lack of raw materials and timber. In the 1770s Robert Townsend Hooe built a wharf on the property. In the process of extending his wharf into the Potomac River, Hooe fortified the marshy Point Lumley with soil, extending the shoreline and making it buildable land. Hooe then proceeded to build a large stone warehouse which functioned as one of Alexandria’s most active shipping terminals. Hooe stored and sold copious amounts of goods that arrived from around the world. He also was elected Alexandria’s first mayor in 1780. He knew George Washington well, dined often at Mount Vernon, and handled much of Washington’s shipping from his wharf. F-1 Hooe’s heirs continued to operate the wharf and warehouse at Point Lumley well into the nineteenth century. In the mid-1850s the American Steam Flour Company built an enormous milling complex on the subject property known as Pioneer Mill. At six stories tall, Pioneer Mill was the tallest building in the city at the time. The complex could churn out 800 barrels of flour per day; grain was brought to it by rail. During the Civil War the Union Army used the facility as a commissary warehouse. After the war the mill was never able to return to its prewar luster. In 1897 a huge fire gutted the complex. Several decades later the block was purchased by the Robinson Terminal Warehouse Corporation. It is believed that some of the original Pioneer Mill structures were renovated and that portions of Robinson Terminal South date to the nineteenth century. 79. If this project is a federal undertaking or involves the use of any federal funding, the applicant shall comply with federal preservation laws, in particular Section 106 of the National Historic Preservation Act of 1966. The applicant will coordinate with the Virginia Department of Historic Resources and the federal agency involved in the project, as well as with Alexandria Archaeology. Code 14 City Compiled Concept Comments Robinson Terminal South DSUP#2014-0006 C-1 All required archaeological preservation measures shall be completed in compliance with Section 11-411 of the Zoning Ordinance.
