We had an excellent meeting on the implications of run-off from codenext vs. current situation. Currently our run-off mitigation measures in existing code are negligible and I believe this is where code-next offers us the more value (we will get density we like it or not). We will see engineered solution of run-offs which will help flood mitigation. (instead of just calling code-next bad let's read what it can do for us better - the car you drive today is a million times better than the one your grandfather drove - so there is value to engineering)

here are few details from Matt Hollon's presentation
23-10E-3030 Engineer’s Certification Required for Certain Alterations and Improvements
(A) The director may not accept any plan or specification for a proposed alteration or improvement of a bed or bank of a waterway unless the plan or specification is accompanied by a certificate bearing the seal of an engineer certifying that:
(1) The hydraulic and structural design is adequate; and
(2) The proposed alteration or improvement complies with the ordinances of this City,the Drainage Criteria Manual, and the laws of this state.
(B) Subsection (A) does not prohibit the director from accepting a plan or specification for a minor alteration or improvement that, in the judgment of the director, does not require certification by an engineer.
Here are few very important links from Mr. Ruven Brooks who is also a wizard with GIS to get maps and data from city GIS
http://www.austintexas.gov/floodpro/ Floodpro shows flood plains throughout the City. I'm always amazed at the number of structures that are actually within flood plains.https://abc.austintexas.gov/web/permit/public-search-other?reset=true If you enter a street name in upper case and select a street type from the pulldown, this site will give you all of the building permits open along that street.https://austin.civicinsight.com/ This is a newer site.
