(1) An expanding population and increased construction of improvements on land coupled with inadequate drainage control have led to stormwater runoff problems affecting both lives and properties. These problems contribute to: 1) increased sedimentation in ponds, creeks, and rivers; 2) degradation of water quality and fish and wildlife habitat through uncontrolled, excess discharge of increased water runoff and transmission of contaminants such as nutrients, oil, grease, and other detrimental substances; 3) uncontrolled water runoff on streets and highways; and 4) erosion and flooding of adjacent and downstream properties. (2) Future problems could be reduced if building and construction activities, both public and private, provide for adequate stormwater quality and quantity controls.

(c) Identify existing drainage features such as streams, conveyance systems, ponds, detention facilities, wetlands, ponding areas, depressions, and such.
(2) Select and delineate pertinent sub basins under existing conditions.
(a) Select homogeneous areas which have generally consistent soils, topography and land use.
(b) Select separate sub basin areas for on-site and off-site drainage.
(c) Select separate sub basin areas for major drainage features.
(3) Determine runoff parameters for each sub basin under existing conditions.
(a) Identify pervious and impervious areas.
(b) Select SCS curve numbers.
(c) Compute time of concentration.
(4) Determine allowable release rates for the appropriate design storms.
(a) Compute runoff hydrographs for each design storm from each sub basin under existing conditions.
(b) For sub basins which drain into an existing storage facility, route the hydrographs for each design storm through the existing facility. This computation will yield the attenuated version of the hydrograph which will be representative for the sub basin under existing conditions.
(c) Sum the appropriate sub basin hydrographs to obtain the total hydrograph for the design storm under existing conditions.
(5) Repeat Steps 2 through 4 for the proposed development conditions.
(6) Determine whether peak flow rate and velocity surface runoff under developed conditions meet those under existing conditions.
(a) If the peak runoff rate under proposed development conditions for the 25-year, 24-hour design storm is less than or equal to 0.2 cfs of the peak runoff rate under existing site conditions, then the concentrated runoff may be discharged through a dispersal trough or other dispersal system provided the Applicant can demonstrate that there will be no significant adverse impact to downhill properties or drainage systems. (b) If the peak runoff rate under proposed conditions for the 25-year, 24-hour design storm exceeds 0.2 cfs of the peak runoff rate under existing conditions, then detention shall be required.
(7) Design and size the detention facility using level pool routing.
(a) Use the developed runoff hydrograph and an iterative process to size the detention facility to meet the required discharge requirements. To meet performance, the developed runoff hydrograph when routed through the new detention facility must not yield an outflow rate greater than the discharge rate for that design storm under existing conditions.
(8) Design and size the new conveyance system for the proposed development. At minimum, conveyance systems shall be designed for the 25 year, 24-hour storm. [Ord. 1161 §6, 1998]

Berm embankments greater than 6 feet in height, as measured through the center of the berm, shall require design by a qualified Geotechnical Engineer licensed in the State of Washington.
(b) Emergency overflows shall be provided at all stormwater storage facilities. The impacts of a system failure at the 100 year, 24-hr storm under developed conditions shall be analyzed to determine on-site and off-site effects. Most likely, an overflow spillway will require the analysis of a broad crested weir. The overflow spillway shall be armored and located to direct overflows safely toward the downstream conveyance system.
(c) All detention or retention ponds, or infiltration ponds should be placed out of the 100-year flood plain or special flood hazards area referenced in Ch. 15.35 LCC, and shall have a minimum freeboard of one foot above the maximum design water surface elevation of the 25 year event under post development conditions.

(j) Constructed and graded detention facilities shall be smoothly or evenly sloped no less than 0.005 ft/ft (0.5% slope) toward the outlet.
(k) The facilities should be designed and constructed to minimize the frequency and difficulty of future maintenance. The Applicant should evaluate the range of potential problems that may occur with the system and determine the corrective action. An Operation and Maintenance (O&M) Manual to be prepared by the Applicant’s engineer is required. The responsibility to implement the O&M manual shall be identified by the Applicant and recorded. All facilities shall be accessible for maintenance and operation. [Ord. 1161 §6, 1998]
(1) Infiltration basins may be selected, designed, and maintained according to the latest edition of DOE’s Manual. Suggested minimum standards shall be Lewis County’s minimum standard. Texture class shall be based on the SCS classified soil type or by field analysis. Soils analysis, including test borings, are necessary for infiltration facilities.
(2) The Applicant shall ensure that the soils information utilized for design is consistent with the actual soil conditions upon completion of construction, prior to final project approval. [Ord. 1161 §6, 1998]
(1) Lewis County requires that such permitted activities address the development’s impact on stormwater quality as well as quantity. The objectives of providing stormwater treatment BMP’s are, for both surface and ground waters, to protect the quality and quantity, and to allow attainment of the designated uses. (2) Stormwater BMP’s are required as part of all development activity. A selection process to determine if a BMP is appropriate for a given use and site outlined in DOE’s Manual should be used to determine appropriate water quality BMP’s. BMP’s which are specified in DOE’s Manual, and those set forth in this Section have been pre-approved for use. (3) The County reserves the right to require an engineering analysis of any proposed practice or design before Approval. Plans not specifically pre-approved are subject to the review and approval by the Administrator. [Ord. 1161 §6, 1998]
