DCM Review

A detailed review of the existing Drainage Control Manual was completed by the consultants and City Staff in January and 0DUFK7KLVUHYLHZLGHQWL¿HGNH\LVVXHV related to the stormwater plan for New Braunfels and prioritization of completing changes. An overview of the recommended changes are summarized below:

Phase II | 13 Community Outreach and Participation Process

Stakeholder Meeting Process

There were two rounds of stakeholder meetings during this process. The purpose was to build upon the four day public input DIWHUWKHÀRRGVLQ,QVWHDGRIKDYLQJ a large meeting where one faction can control the conversation, our approach was to have a series of two-hour meetings with likeminded stakeholder groups. This enabled the conversation to stay focused on the point of view of the stakeholder group.

7KH¿UVWURXQGRIVWDNHKROGHUPHHWLQJVZDV a series of focus group workshops over a two day time period on October 9 and 7KHSXUSRVHRIWKLV¿UVWURXQG of meetings was to introduce the process, gather priorities on stormwater strategies for the community and present best management practices (BMP) as it relates to stormwater management.

The second round of public meetings was a series of focus group workshops over a one day time period on January 22, 2012. These meetings focused on the prioritization DQGORFDWLRQRIVSHFL¿FLPSOHPHQWDWLRQ tools associated with preferred stormwater strategies gathered from the last series of meetings.

14 | Phase II New Braunfels Stormwater Management Strategy | New Braunfels, Texas Stormwater Strategy Options

Strategy Development

Stormwater strategies were developed through the review of existing documents, review of approved EPA mechanisms and consultation with City Staff.

The City of New Braunfels has an existing MS4 permit and a Drainage Criteria Manual that currently guides stormwater management. A review of these documents was completed to gather a base understanding of existing stormwater strategies in the City.

The Environmental Review of approved EPA mechanisms supplemented the list of stormwater strategies with green infrastructure options that have multiple EHQH¿WVIRUWKH&LW\

$¿QDOOLVWRISRWHQWLDOVWRUPZDWHUVWUDWHJLHV was created in consultation with City staff after review of the above strategy options. Strategy Details

For each stormwater strategy, a brief description was created based upon the common understanding of the strategy in City or governmental materials. This description was followed with a list of EHQH¿WVDQGOLPLWDWLRQVRIHDFKVWUDWHJ\ Finally, each strategy included information on the typical scale at which the strategy may be applied (site, community, regional) and the phase of the project the strategy is most applicable to (policy, design and construction,operations, maintenance and monitoring).

The following pages have the above information summarized. Appendix B has full cards that were used for each strategy during the public engagement process.

Priority Strategy Implementation Options

In order to best understand the implementation options, the current conditions in New Braunfels were evaluated VSHFL¿FWRHDFKVWUDWHJ\7KLVHYDOXDWLRQ SURYLGHGDQH[LVWLQJFRQGLWLRQVSHFL¿FWR each strategy.

A series of case studies around each of the strategies was then completed to better understand how other cities similar to New Braunfels have implemented similar strategies. These case studies were based upon four criteria: comparable size to New Braunfels, economy has river-based tourism, regionally similar with priority to Texas examples, and presence of MS4 permit.

The proposed implementation options for each strategy are based on the case studies and extensions of the strategies that New Braunfels currently has in place. These proposed implementation options are summarized at the end of this chapter.

The following pages outline each strategy, explaining the actions that New Braunfels has already taken to address the strategies, the recommendations that were pulled from the corresponding case studies and the proposed implementation options for New Braunfels.

Proposed implementation options are explained in Phase III of this document.

New Braunfels existing impervious coverage restrictions currently focus on landscape. The planning director may require a SURIHVVLRQDODUERULVW¶VUHSRUWWKDWGH¿QHV the impact of a development upon existing trees affected by proposed construction and impervious cover limitations adjacent to protected trees.

Landscaping is accepted as adding value to property and is in the interest of the general welfare of the city. The provision of landscaped area also serves to increase the amount of a property that is devoted to pervious surface area which, in turn, helps to reduce the amount of impervious surface area, stormwater runoff and consequent non-point pollution in local waterways. Therefore, landscaping is hereafter required of new development as provided in this section, except landscaping is not required for single-family and two-family, and agricultural uses.

Case Study Recommendations

Austin, Texas - The Edwards Aquifer Recharge Zone Building Limitations limits impervious cover and density in the Edwards Aquifer Recharge Zone. Developers may transfer impervious cover or development rights. The Limitations also specify stormwater treatments and construction management, require detention and stream bank setbacks or buffer zones.
