Storm drain system

Underground storm drain pipes

Watershed boundaries

Water quality impacts from stormwater

13

• Stormwater runoff erodes local streams, carries sediment, nutrients, bacteria, petroleum, and litter downstream, kills trees, affects habitat for aquatic organisms, and damages sewer lines

• Sediment and nutrients are major pollutants of concern for Chesapeake Bay

Stormwater program goals

14

• Protect public health, safety, and property

• Reduce development impacts on water quality in local streams, the Potomac River, and the Chesapeake Bay

• Comply with state and federal regulations• Municipal Separate Storm Sewer System

(MS4) permit• Chesapeake Bay cleanup requirements• Floodplain management

Basic program elements

15

• Stormwater infrastructure• Flood risk reduction• Adding stormwater management for existing

development• Regulation of new development• Stream restoration• Pollution prevention for public and private

activities• Outreach, education, and monitoring

Stormwater Master Plan

16

• Adopted by County Board September 2014

• Evaluates current state of stormwater management and condition of storm sewers, streams, and watersheds

• Provides comprehensive framework for managing stormwater, streams, and watersheds for next 20 years.

• Incorporates 3 technical needs assessment studies that identified priorities and led to current CIP project proposals:

• Stream inventory• Watershed retrofit plans• Storm sewer capacity analysis

MS4 permit and Chesapeake Bay cleanup requirements

17

• Major program driver with quantitative nutrient and sediment reduction requirements and regulatory deadlines

• Stormwater Master Plan and CIP provide strategy and funding

• MS4 permit also requires a broad range of programmatic and operational requirements to reduce stormwater pollution

Resource Protection Areas (RPAs)

19

Overview

20

• Established under Chesapeake Bay Preservation Ordinance

• 100’ buffer from the banks of a stream (wider where steep slopes exist)

• Additional controls on development activity• Goal is net stream buffer improvement in terms

of vegetation and habitat• Compatibility with streamside passive

recreation and aesthetic and habitat improvements

Exceptions Process

21

• Exception required for projects that increase RPA encroachment or impervious area, or move structures closer to stream

• Chesapeake Bay Ordinance Review Committee reviews most exception requests associated with redevelopment in RPA

• Types of mitigation:• Tree replacement or protection• Overall vegetative enhancement• Invasive plant removal/control• Additional stormwater management

measures• Enhanced erosion control measures during

construction

Floodplain Management Ordinance

23

Overview

24

• Residential development in or adjacent to FEMA designated 100-year floodplain must meet these requirements:• Lowest level elevation must be one foot

above 100-year flood elevation• Footprint of structure must be at least 15

feet horizontally from floodplain• Non-residential – Meet above OR flood-proof

structures.• No encroachment in 100-year floodplain without

analysis demonstrating no significant impact

• New flood data will be used to update map in study area – ~5 years

Stormwater Management Ordinance

28

Overview

29

• Required by State in response to Chesapeake Bay cleanup requirements

• Arlington Stormwater Management Ordinance adopted by County Board effective July 1, 2014

• Regulatory threshold is 2,500 SF of land disturbance

• Stormwater management compliance level of effort is driven by the increase in impervious cover for the project

Performance standard summary

30

• 10% to 20% net pollutant load reduction.• Protect downstream properties from increases

in runoff volume• Control construction impacts• Typical compliance techniques include:

• Stormwater planters• Bioretention• Pervious pavements• Underground filter systems• Infiltration

‘Illicit discharges’ and pollution ‘hot spots’

31

Overview

32

• MS4 permit requires programs to address pollution incidents and potential pollution sources

• Combination of techniques, including inspections, monitoring, and technical assistance and outreach

‘Hot spot’ inspections

33

• Industrial and commercial facilities with high pollution potential

• Auto-related businesses and restaurant strips most common in Arlington

• Coordinate with multiple agencies to resolve issues and conduct enforcementHealth Department, Fire Marshal Office, Code Enforcement, Solid Waste

Storm drain screening

34

• Includes S. Four Mile Run Drive area• Collection of stormwater and ‘dry weather’

samples• Concentrated auto-related services contribute to

petroleum pollution seen in stormwater runoff• Larger road network also a major source

Challenges

35

• Existing, older development and site constraints

• Lack of awareness• Incidents often occur after hours• Turnover of property managers and/or

tenants • Limited enforcement authority

Redevelopment of sites will provide much stronger opportunity and authority to address pollutant impacts.

Pollution Preventionhttps://environment.arlingtonva.us/streams/prevent-pollution/

36

• Targeted outreach to business community• Educational materials and technical guidance

• Community meetings • Collaboration between business community, civic

associations, and County

• Outreach to public• How to report illicit discharges and prevent pollution

• Is one element of the County’s Comprehensive Plan

GLUP overview

77

• History of the General Land Use Plan• First GLUP adopted in August 1961• GLUP amendments incorporated into 11 published

documents to date (1961, 1964, 1966, 1975, 1979, 1983, 1990, 1996, 2004, 2011)

• GLUP amendment map on-line is updated semi-annually

• Amending the General Land Use Plan• The GLUP may be amended to more clearly reflect the

intended use for a particular area through three processes:

• As part of, or an implementation recommendation resulting from, a long-range planning process for a designated area (e.g. 4MRV study); or

• With a site plan or other development proposal (typically where consistent with recommendations in an adopted plan)

• As a result of a Special GLUP Study based upon an individual request (e.g. development proposal)

Zoning Overview

• Zoning is a land use regulatory tool developed in the early 20th Century

• Rooted in the Police Powers of the United States Constitution

• New York City enacted the first zoning ordinance in the United States in 1916

• Based on concept of separating land uses and regulating placement of structures on the lot

• Euclidean zoning (e.g. R-districts, C-1, C-2, M districts in Arlington)

• This model of zoning has evolved over the years to many different models, allowing for:

• Mixed-use zoning (e.g. Arlington’s Metro corridors)• Form Based Codes (e.g. Columbia Pike)• Planned Unit Developments• Cluster development

82

Zoning Overview

• Enabling authority for Arlington’s Zoning Ordinance comes from the Code of Virginia

• Ordinance includes text and a map

• Arlington’s first Zoning Ordinance was adopted April 26, 1930, based on a “pyramid” structure

• ZO Substantially amended in 1950 and 2013

83

Zoning Overview

• Zoning Ordinance is one tool to implement the County’s Master Plan

• As part of development of a plan in Arlington, it is typical to consider whether the Zoning Ordinance should be amended to implement the plan

• Arlington Zoning Ordinance includes 3 types of use allowances:

• By-right uses – approved by Zoning Administrator when in compliance with the Ordinance provisions

• Special Exception uses:• Use permit – conditional uses, require approval by the

County Board and may include conditions to mitigate impacts

• Site plan – special exceptions, require Planning Commission and County Board approval, and used in Arlington to implement incentive zoning enabled by VA Code

90

Industrial Land Use and Zoning Study (2000)• This study focused attention on the area’s potential for

redevelopment in the face of waning industrial use

• The study found that the County no longer needs industrial uses* to perform successfully

• But, it also found that some industrial uses should potentially be preserved because of their value to the County

• Such uses could potentially be incorporated into non-industrial zoning districts through special exception processes with performance standards

• A major recommendation was to further study this area

* However, additional consideration of the Concrete Batching Plant is warranted.

91

Nauck Village Center Action Plan

• The vision is for a mixed-use, pedestrian friendly environment centered around a “town square” bordered by 4-5 story buildings with retail on the ground floor/housing above

• To the north of the square, the scale of development would decrease with residential uses predominating

• To the south of the square, the scale of development would increase with a greater emphasis on mixed-use development

• Roadway elements address the needs of pedestrian, bicycle and vehicular traffic

• Urban design guidelines further the goal of an attractive and vibrant mixed-use environment

92

Nauck Village Center Action Plan (2004) Winner of a 2005 Virginia Chapter of the American Planning

Association Award

Plan was adopted as a revitalization plan for the commercial area of the Nauck neighborhood
