11.This development is subject to the provisions of SMC Chapter 12.24, which pertains to the construction and maintenance of on-site stormwater detention facilities. Two facilities were constructed to serve the entire Perimeter Park industrial subdivision. Therefore, no further detention improvements are required for this development.
12.The site grading, erosion and sediment control measures required for this development shall be designed according to the standards in the Shawnee Manual of Technical Specifications and Design Criteria.
The conceptual grading plan shown for this development appears to be in substantial compliance with City standards. Any design issues discovered during the review of the site development plans must be resolved prior to the issuance of a building permit.
The applicant is responsible for submitting a rough grading plan as an integral part of the site development plans submitted for a building permit. The grading plan must accurately show contours of the existing ground elevations and details of area drainage and terrain, including identification of areas with existing or proposed gradients greater than 33 percent. The plan must also show contours of the finished ground elevations to be achieved by the proposed grading activities plus all grading within public rights-of-way, and typical cross-sections of all proposed drainage channels and swales. Existing and proposed contours must be shown extending at least 200 feet beyond the boundaries of the development site at 2-foot intervals.
The applicant is also responsible for submitting an erosion and sediment control plan as an integral part of the site development plans submitted for a building permit. The erosion and sediment control plan must show the type and location of all proposed measures, which will include at least one temporary construction entrance. Staff may require the plan to show additional measures, including diversion channels and siltation basins, at such locations as may be necessary to retain eroded material on the development site. Also, the plan must include general notes on installing and maintaining siltation control measures and restoring vegetation on disturbed areas, an installation schedule, details of any special grading activities, and standards details of all proposed measures.
13.Erosion and sediment control measures are required for all land disturbing activities. The applicant is responsible for installing all such measures shown on the approved plans prior to commencing any grading activities. The applicant is also responsible for maintaining such measures throughout construction until vegetation is established over the disturbed areas. Staff may require additional measures as may be necessary in the field to repair eroded areas and retain sediment on the development site. The applicant is responsible for installing such additional measures or repairing existing measures within 72
