§ 35-B105. ERZD Documentation.

(a)

Aquifer Protection Plan.

(1)

Number of Copies. The applicant shall provide fifteen (15) folded prints and computer disk of the proposed ERZD Documentation. One (1) eight and one-half by eleven (8½ x 11) inch reduced copy of the plan shall also be provided.

(2)

Format. Plats shall be drawn in India ink on Mylar on sheets eighteen (18) inches wide and twenty-four (24) inches long, with a margin of two and one-half (2½) inches on the left side of the sheet, and appropriate margins on the other three (3) sides. Plats shall be drawn at a scale of one hundred (100) feet to one (1) inch unless a smaller scale is approved by the director of planning and development services. Plats which include one-half (½) acre or less in area shall be drawn at a scale of fifty (50) feet to one (1) inch.

Where more than one (1) sheet is necessary to accommodate the entire area to be subdivided, an index sheet showing the entire subdivision at an appropriate scale shall be attached to the plat.

(3)

Contents. The application and site development plan for an aquifer protection plan within the ERZD shall contain the information required by this section unless the San Antonio Water System determines that, due to the scope and nature of the proposed development, some of the information is unnecessary:

A.

The date, scale, north point, and key plan showing the location of the tract on which the development is to take place.

B.

The existing boundary lines, and acreage of the tract on which the development is to take place, and the common boundary lines and names of the owners of adjacent properties.

C.

Identification of all floodplain preservation areas, floodplain buffer zones, significant recharge features and buffer zones, and all such other areas with restrictions as required by this appendix.

D.

A detailed erosion/sedimentation control plan and construction sequencing plan required by subsection 35-521(g).

E.

A detailed drainage plan and street layout that comply with the requirements of this appendix.

F.

Engineering drawings showing compliance with the applicable requirements of this appendix for control strategies on development.

G.

A report, site plan, and other relevant information addressing the best management practices as required by subsection 35-521(p).

H.

A topographic map, drawn to a scale of one hundred (100) feet to one (1) inch, or in an appropriate scale. The map should display, according to the best information available, topographic information and features (including, but not limited to, faults and fractures along waterways and sinkholes), and the floodplain preservation areas.

I.

The location, type of use, and total percentage of proposed and existing impervious cover on the site, in conformance with this appendix.

J.

Location of all temporary and permanent runoff detention basins, constructed and altered waterways and other physical facilities to be installed to comply with the terms of this appendix.

K.

An affidavit from the appropriate affiant showing accepting legal and financial responsibility for structural controls, maintenance cost, monitoring, and remediation.

L.

Final plans for underground utility installation shall be submitted with the site development plan and shall show minimum construction corridor widths.

M.

Location of all monitoring stations, sample points or other significant devices used in measuring or assuring water quality.

N.

Any baseline data from surface water samples required to be taken or maintained under regulations established by the San Antonio Water System.

O.

A maintenance plan which provides the proposed schedule and details of maintenance which will be performed to ensure the proper operation and effectiveness of all control structures.

P.

Special notes or attachments as may be required by other sections of this appendix.

(4)

Certification. The site plan required by this section shall be sealed by a registered engineer and by a registered landscape architect with regard to elements of the plan within their respective disciplines. In the event a site plan is amended by an applicant, the above requirements (subsection (3)), shall be updated to the extent they are affected by the amendment.

(b)

Applications for Rezoning. A report containing the information prescribed in subsection (a) is required for all applications for rezoning within the Edwards Recharge Zone District. See section 35-B117, below.

(c)

Erosion and Sedimentation Control Plans.

(1)

Plan Contents. The erosion and sedimentation control plans required by subsection 35-521(t) shall include the following items:

• Construction sequencing as it relates to placement, maintenance, removal of temporary erosion controls, and restoration measures. The sequencing plan schedules these items in the overall scheme of development.

• A list of such erosion controls and maintenance thereof.

• Slope stabilization techniques to be employed.

• Restoration plans including vegetative types.

(2)

Sequencing Plan. The erosion control and construction sequencing plan shall include the following items:

• Location of temporary erosion controls with maintenance note. The plan shall show the physical details of the controls.

• A construction sequencing list, including the timing of the use of various controls in relation to steps in the construction.
Restoration techniques and acceptability note.
