Management PlanChristi Upton817-748-8638

Public Works Department


A 35 Year Perspective

• Doubled the number of waterways safe for fishing and swimming

• Reducing industrial discharges by billions of pounds a year

• More than doubled number of people served by adequate sewage treatment

• Reduced annual wetland losses by 75%

• Reduced soil erosion from cropland by more than 1/3 Ohio’s Cuyahoga River Fire of 1952 (and again in 1969)

Still…•40% of nation’s waterways are too polluted for fishing and swimming•2,200 annual health advisories against consumption of contaminated fish•Extensive (>8,490 mi2) hypoxic zone (won’t support life) in Gulf of Mexico (2002)

In 35 years since the Clean Water Act the United States has…


History of Storm Water Policy

• 1956 to 1972 – series of federal pollution control acts aimed to improve water quality

• 1972 – National Pollutant Discharge Elimination System enacted and beginning of Clean Water Act

• 1987 – Clean Water Act Amendments– Establishes schedule for industrial and municipal storm water

discharge permits. Municipalities required to have controls to reduce pollutant discharges

• 1990 – Phase I – municipalities greater than 100,000 in population

• 1999 – Phase II – all small municipalities in urbanized area– 2003 – court case prevented Texas from issuing a state storm water

program for urbanized municipalities


Phase II Storm Water Permit

• Permits the discharge of storm water to waters of the US from the MS4– provided the City:

• Prepare a Storm Water Management Plan• Submit Plan to TCEQ by February 11th, 2008• Reduce amount of pollutants entering waterways

via implementation of Plan• Five Years to implement

illicit discharges– Educate staff and public to be the “eyes and ears”

and who to notify about illicit discharges


Construction Site Storm Water Runoff Control

• Requirements:– Ordinance to require erosion and sediment controls– City to require that contractors to implement appropriate erosion

and sediment controls– Develop procedures to review site plans for erosion and

sediment controls

• Southlake’s Goals– Develop an ordinance and enforcement procedures– Develop site review procedures specific to erosion and sediment

controls– Provide education for staff on erosion and sediment control

inspections– Provide education for construction site operators


Post-Construction Storm Water Management in New Development and

Redevelopment• Requirements:

– Ordinance to address post-construction runoff– Ensure adequate long-term operation of BMPs

• Southlake’s Goals:– Develop an ordinance and enforcement procedures– Develop plan review procedures that address post-

construction runoff controls– Inventory post-construction controls in Southlake– Encourage developers to consider Low Impact

Development designs during planning stages


Pollution Prevention/Good Housekeeping for Municipal Activities

• Requirements:– Identify housekeeping measures and BMPs– Implement housekeeping measures where needed

and maintain current BMPs– Provide training for staff– Properly dispose of waste

• Southlake’s Goals:– Provide training to staff annually– Audit all municipal activities and facilities for potential
