2 Outline 1. Overview of Current Operations a. Leaf Storage b. Mulch Distribution c. Salt Staging and Distribution 2. Long-Term Operational Needs a. Maintain Current Leaf, Mulch, and Salt Operations b. Provide Shift Change & Support Facilities 3. Existing Site Environmental Practices 4. Public Space Considerations a.

3 Primary Objective for 26th/Old Dominion Site To improve effectiveness and efficiency of snow operation services for the North side of the County in the most environmentally and community sensitive manner feasible, while maintaining existing leaf and mulch operations 1. Winter Storm Response Facility a. Enables faster completion of snow and ice clearing or treatment (gain varies by storm event, but typically results in a 10-15% gain) b. Provides a cost-effective and higher level of service by reducing deadhead time during treatment c. Chain shop keeps trucks operational during icy or heavy snow conditions 2. At the same time: a. Maintain Leaf Storage and Mulch Distribution operations b. Address current site deficiencies including zoning setbacks, appropriate screening and buffers relative to adjacent uses 26/Old Dominion Task Force 3

5 Current Operations Leaf Storage & Mulch Distribution Leaf Storage Area Mulch Distribution Area 26/Old Dominion Task Force 5

6 Current Operations Leaf Storage & Mulch Distribution Leaf Storage includes the collection, storage, and off-site processing during the winter months (Nov.- Feb.) 26 th St N. site stores 60% of leaves collected in Arlington's leaf vacuum program (approx. 2,300 tons serving 33 Civic Associations) Existing site can: Serve 16 leaf collection trucks Average four loads/day/truck Maximum six loads/day/truck 26/Old Dominion Task Force 6

7 Current Operations Leaf Storage & Mulch Distribution Mulch Distribution represents a satellite mulch distribution center for residents throughout the year 26 th St N. Site Characteristics: Approx. 1,000 tons of mulch delivered to site annually Separate bays for wood and leaf mulch; size varies w/ season Mulch deliveries vary with season: Peak wood mulch demand - July (18 deliveries) Peak leaf mulch demand - April (14 deliveries) 26/Old Dominion Task Force 7

8 Current Operations Salt Staging and Distribution Salt Dome Interim Salt Storage Facility 26/Old Dominion Task Force 8

9 Current Operations Salt Staging and Distribution Salt Operations include the staging and distribution of salt during each winter and spring (Nov.-Apr.) 1. Winter Operations (Nov.-Apr.): a.

10 Current Operations Salt Staging and Distribution Salt Loading and Refilling A backhoe (pictured) or loader is required to load salt from storage facility onto trucks Salt refilling frequency dependent on truck size and storm severity. o Larger trucks could be as frequent as every 3-6 hours o Smaller trucks could be as frequent as every 1-2 hours 26/Old Dominion Task Force 10

15 Long-Term Operational Needs - Winter Storm Response Overall Program area of approx. 60,000 SF Maintain 6,000 Ton capacity Site elements to include: Covered storage of (~25) V-box spreaders & plows Brine Mixing & Storage Tanks Program for road pre-treatment Brine making machine Four 2,000-5,000 Gal. Capacity Tanks (salt brine solution) Efficiency of operations before storm equally important 26/Old Dominion Task Force 15

16 Long-Term Operational Needs - Winter Storm Response Additional Site Elements to include: Shift Change Facility Shift change operations during the winter months Evaluate potential off-season uses Architecturally appropriate, depending on location Chain Shop Pull through bay for installing/storing chains Collocated with the salt storage structure, spreaders and part of the shift change facility Light vehicle & equipment maintenance Administrative Office Break Area/Dispatch operations/training Seating with tables for up to 40 occupants 26/Old Dominion Task Force 16

17 Long-Term Operational Needs - Winter Storm Response Shift Change Facility - Support Spaces Restrooms Kitchenette Locker Room Storage Telecom Room Emergency Generator Circulation Parking 26/Old Dominion Task Force 17

18 Long-Term Operational Needs - Overall Site Site planning will need to reserve additional areas to allow for: Fire Lanes Ingress & Egress to the site Large vehicle turning radii Site security Zoning Setbacks Stormwater Management Facilities Buffering and Screening* *Site screening and/or buffer space requirements TBD, after placement of major program elements is determined 26/Old Dominion Task Force 18

19 Long-Term Operational Needs - Program Summary Estimated Range of Space Needs* (in SF) Existing On-site (in SF) Leaf Storage 30,000-35,000 37,000 Mulch Distribution 3,500-5,000 5,000 Salt Operations 55,000-65,000 57,000 Shift Change Facility 4,000-5,000 N/A Parking (peak parking) 25,000-35,000 Limited/Unmarked at Site Additional Site Elements (Site circulation, buffers, etc.) 30-40% Included in Programs Above/currently deficient Total Site Area Needed* acres 2.3 acres * Estimated areas are subject to change based on further design, inclusion of screening and buffers, and evaluation of parking alternatives. Site design will iterate with intent of dual-use and opportunities for efficient configuration of site elements. 26/Old Dominion Task Force 19

20 EXISTING SITE ENVIRONMENTAL PRACTICES 26/Old Dominion Task Force 20

21 Existing Site Environmental Practices Environmental mitigation measures have been implemented on site to facilitate Leaf Storage & Mulch Distribution along with Salt Operations. Both operations require compliance with their respective Stormwater Pollution Prevention Plans (SWPPP) for the defined site use. Primary pollutants of concern at this facility include sediment, nutrients, hydrocarbons (fuel, oil), hydraulic fluid, and trash. 26/Old Dominion Task Force 21

28 Draft PSMP - Land Acquisition Policy (page 139) Generational or Unique Opportunities: Defined as an acquisition opportunity that, if not acquired at the point of availability, would likely become redeveloped to the point it would never become an opportunity again. Missionhurst Note: The County s typical method for acquiring land for creating or expanding parks is to make offers to purchase said properties when they are put on the market for sale. 26/Old Dominion Task Force 28

29 Draft PSMP Statistically Valid Survey Sample Size Goal for number of surveys to be completed: 800 Survey response exceeded the goal: 1,470 surveys completed Demographics of survey respondents accurately reflect the actual population of the County Survey Results Generated Top 3 Outdoor Facility Needs: 1. Paved Multi-Use Trails 2. Natural Areas & Wildlife Habitats (Casual Use Spaces) 3. Hiking Trails 26/Old Dominion Task Force 29

30 Draft PSMP - Casual Use Spaces (page 60) Priority Action 1.3. Ensure access to spaces that are intentionally designed to support casual, impromptu use and connection with nature.

33 Draft PSMP - Level of Service (LOS) (page 169) No national uniform level of service standards exist for parks or recreational amenities across the country. However, there are generally 2 types of standards communities use to analyze service: population-based standards and access standards. Both will be updated every 5 years for Arlington County. Population Based Indicates the quantity of each amenity Arlington needs between now and 2035 (verifies whether the County has a surplus or deficit of any particular amenity. Mapped LOS Indicates, based on geography, where Arlington may need additional/fewer amenities or improved access to those amenities. 26/Old Dominion Task Force 33
