Carbon Footprint: Building Construction
2015 International Energy CodeLEED
Leadership in Energy & Environmental DesignFundamental Commissioning (assures systems & equipment designed, installed & tested according to owner operational requirements)
Enhanced Commissioning, fundamental commissioning + participation during the design phase and project post-construction follow-up
Com-Check is required during building permit phase to show overall energy calculation meets energy code requirements
Review and certification by US Green Building Council
Recycling of building materials is not required Recycling of building materials requiredCompliance with code confirmed through building permitting phase
Design team collects information & performs calculations to satisfy requirements
Result is a sustainable building without 3rd Party certification

Natural Environment: Urban Wildlife
Honey Bees Arlington is the 100th city to be certified as a Bee City USA affiliate Commitment includes
– hosting annual educational event or habitat restoration day– creating & expanding bee-friendly habitats
Monarch Butterflies Champion Status through the National Wildlife Federation’s
Mayor’s Monarch Challenge program Commitment includes
– public communication & engagement– demonstration gardens
POTENTIAL ACTIONS Continue to focus on long-term adverse
conditioning to keep wildlife away from residents
Enhance GIS mapping of animal sightings Other
Natural Environment: Arlington’s Cross Timbers Ecoregion
Woodlands dominated by post oak, blackjack oak, cedar elm, hickory, osage orange, eastern red cedar, mesquite, bumelia, hawthorn, & greenbriar
Urban growth & expansion impacts wildlife habitat
Consideration of:− historic tree area designation− regulatory approach for preservation
POTENTIAL ACTIONS Options for recognizing Arlington Cross Timbers
Region as historic: − Old-Growth Forests− Sites of Special Scientific Interest− Heritage Tree Designation
Work with Texas Historical Tree Coalition to determine a designation that is accurate and practical for Arlington

Goal is to increase the City’s resilience to floods Program managed primarily in Public Works &
Transportation− New development review is within Planning and
Development Services City has participated in National Flood Insurance
Program since 1974− 2,191 structures in FEMA floodplain− 60 identified localized drainage areas− $21,141,873 in flood insurance losses since 1977− Only 25% of structures in floodplain have
insurance
29
Stormwater: Program Overview
Stormwater: Private Infrastructure Design
30
PREVIOUS DESIGN CRITERIA CURRENT DESIGN CRITERIABMP requirements based upon disturbed area BMP requirements based upon final impervious areaMaintenance requirements could be on face of plat Maintenance Agreements filed with County for every
stormwater storage facility and BMPNo operations & maintenance plans or designated funding source for long term maintenance
Operations & Maintenance Plan
Allowed for increases in flood heights and stream velocities up to 5% from predevelopment conditions
Designate a Funding Source to Maintain
Compensatory storage for fill in floodplain was optional
Verification of post construction BMP installation
Stormwater storage facilities required when project outfalls to a system with flooding or a system without capacity to contain design stormCompensatory storage is required for fill in floodplain
Maintenance Agreement Enforcement− Stormwater Management Plan is currently under review by TCEQ− City will have to have an inspection and enforcement program for private BMPs− City will need to monitor BMP effectiveness− Locate private stormwater infrastructureo Stormwater Storage Facilitieso Nearly 20 years of underground private BMP construction will be hard to verify
Focus on education before enforcement− Understand maintenance responsibilities
Stormwater Pollution Prevention Code update needed− Clarify Maintenance Agreement enforcement− Clarify Automotive Related Businesses inspection & enforcement
31
Stormwater: Private Infrastructure Maintenance
Protect Arlington’s Waterways Campaign− Only Rain in the Storm Drain− Report Illegal Dumping− Fall outreach efforts focus on proper disposal of leaves− Spring outreach targets grass clippings and lawn waste− HOA meetings, adult education classes, neighborhood events− Stormtalker Education Program
Turn Around, Don’t Drown Floodplain Program for Public Information Plan− Developed by Committee of residents and staff− Adopted by Council January 2020− Identified target audiences − Identified new outreach projects
32
Stormwater: Public Education and Outreach
33
Stormwater: Comprehensive Plan
Data Collection Develop new hydrologic & hydraulic models for all
watersheds Update Design Criteria Manual & Stormwater related
ordinances Identification of flood prone areas & structures Identification of mitigation projects & flood buyout
locations Identification of operations and maintenance needs Identification of regulatory needs Development of a project prioritization system Implementing business strategy to regularly update CSP Identification of future funding needs
34
Present Comprehensive Stormwater Plan to Transportation & Municipal Infrastructure Committee in December 2020
Present Comprehensive Stormwater Plan to Council for consideration & adoption in early 2021
Update Stormwater Pollution Prevention Code to include inspection of Automotive Related Businesses & Private Stormwater Drainage Facilities in December 2020
Discuss long term financial needs to implement Comprehensive Stormwater Plan in 2021

Stormwater: Commercial Development Drainage Process
Construction plans
submitted to City for review.
Proposed plans reviewed by
City.
Once the plans meet City requirements,
permits are issued for construction.
Public grading & drainage inspected for
conformance with construction plans by
Public Works inspectors.
Private grading and drainage (parking lots & open space) inspected for conformance with construction plans by Developer’s engineer.
Require the development to provide a post-
construction topographic survey & verify the finished lot grading
conforms to engineered permit plans.
Certificate of Occupancy Issued & project
complete.
POST-CONSTRUCTION SURVEY
Cost varies by size of parcel and drainage patterns.
Effects on obtaining Certificate of Occupancy.
Residential adjacency only.
