For more see n This Catalog This catalog features all -new Play Areas. It is not just a new cover over old material. All of the new play areas, plus many of the SeparateSTm and accessories were created to address the most recent governmental specifications and recommendations. These include the U.S. Consumer Product Safety Commission (CPSC), the American Society for Testing and Materials (ASTM), F-1487-01 "Standard Consumer Safety Performance Specification for Playground Equipment for Public Use,"the Americans with Disabilities Act, and European standard EN 1176 as independently certified by TUt! Playground equipment appearing in this catalog has been carefully developed or critiqued based upon these guidelines and playground specifier/owner/operator concerns communicated to us regarding playground safety, accessibility and durability. History Over thirty-five years ago, TimberForm initiated the Playground Revolution. The form and function of contemporary play facilities were immediately and forever transformed. Today's finest play structures and accessories evolved from radically new concepts originated by TimberForm designs, Later, PipeLine play systems, "the toughest metal play system in the world", replicated in steel the post and deck concepts of successful TimberForm designs and the evolution continued. Subsequently, the introduction of TimberForm-2 offered a new modular post and deck system that reduced the need for many embedded posts and allowed for simplified installation by community volunteers. Friends and neighbors could erect a significant TimberForm-2 play structure in a few hours on a weekend, The state of play equipment design after the year 2000 is best described as one of evolution rather than revolution. Accessibility to all players is now a prime consideration in the equipment selection process. Plus, enhanced safety features make today's playgrounds the most player- friendly ever. Columbia Cascade has been committed to both accessibility and safety since its origin. Couple this with innovative design, structural integrity, premium materials, durable finishes and the widest product selection offered in the playground equipment industry and it's easy to see why today TimberForm & PipeLine remain the informed specifier's choice. Accessibility for All Accessible play areas and accessories are identified throughout the catalog with this graphic symbol. Columbia Cascade has long been active in the design and production of play structures that serve the needs of all children. Many states and the Federal Americans with Disabilities Act make accessibility for all children a key consideration in playground design and equipment selection. Accessible play areas from each of our play systems as well as several Separates and Accessories are presented in this catalog. The same may be said for those unique playground equipment designs we create "For Signature Projects", Safety Columbia Cascade has actively and enthusiastically participated in the improvement of playground equipment safety performance standards and guidelines for public playgrounds since they were first proposed_ The products presented in this catalog reflect playground equipment safety specifications at the time of publication. However, it should be noted that the most significant safety factor relating to playground injuries remains the surface beneath and around the equipment. As an equipment manufacturer, we have no control over this most important safety aspect. Therefore, we cannot emphasize the following statement too strongly. It is the most important message you will see in this catalog. Under no circumstances should play equipment be placed in service upon hard, unyielding surfaces such as concrete, asphalt, compacted earth or turf (natural or synthetic). We supply TimberForm & PipeLine playground equipment to customers worldwide. Many of these specifiers rely upon EN 1176 as their criteria for safe, durable playground equipment. Engineers from TOV, an internationally recognized independent testing agency headquartered in Germany, have inspected our engineering data, factory, materials and quality control systems and products in situ. TOV certifies TimberForm & PipeLine playground equipment to be in compliance with tough European specifications, By simply replacing the U.S.A.-standard slide chutes with our Euro slide chutes featuring safe 6-inch-high (15cm) side rails and rounded exit, most TimberForm & PipeLine play areas will comply with EN 1176. We receive many requests from potential customers who want to buy TimberForm or PipeLine components or accessories for attachment to apparatus they have designed and had constructed. Because we have no real knowledge of their apparatus; its structural qualities, materials, placement, or how our component or accessory may, in combination, create a hazard to children, we never sell our products for attachment to apparatus we did not make. CASPAX-7� Powder Coating POWDER All TimberForm & COATFD PipeLine colored" T metal is finished with CASPAX-7 lead-free powder coating. CASPAX-7 provides thick, rich colors that are ultraviolet (UV) stabilized, durable and smooth— free from runs, drips or sags. This dry finishing process emits no volatile solvents to the atmosphere and is ecologically sound. See page 10 for more information. Colors a% F To view the complete selection of available powder -coating colors, ask your representative to show you the Columbia Cascade ColorBook.Tm Plastic Accessories Rotationally -molded plastic products that accessorize TimberForm & PipeLine playground equipment are the finest available. Spiral, Straight, Wave and Tube Chutes, Tunnel Crawls, Bubble Panels and cylindrical accessories such as Tic-Tac-Toe, Spelling and Addition panels are manufactured from hot -compounded medium density polyethylene (MDPE). Hot -compounding assures uniform coloration within each part and from part to part. No blotchiness or variation between parts is particularly important when plastic parts are. used contiguously. Hot -compounding also imparts superior ultraviolet (UV) resistance to minimize the fading effects of the sun's rays. Maximum UV protection also enhances the strength properties of MDPE, As the company known for manufacturing "The World's Toughest Playground Equipment" we make our plastic accessories from tougher medium density polyethylene not low density. The final wall -thickness of our rotationally -molded plastic accessories is 50% thicker than the industry standard adding to durability. Beware specifying or buying cheap vacuum -formed plastic accessories often used on home playground equipment. These products may appear similar in promotional photographs. but in reality they fail to provide durability to last more than a few days in a public playground environment. Timber TimberForm uses playground equipment grade Douglas fir which is free -of -heart -center (F.O.H.C.). The F.O.H.C, specification is critically important, Timber containing the tree"s heart or pith will perform poorly and have a short useful life, After seasoning, smooth dressing and fabrication, all wood components are inspected for appearance and suitability for play. Douglas fir is a tough and durable structural species ideally suited to the demands of playground use when premium grades are used. It will vary in color from shades of salmon to ivory and eventually turn to a natural mid - gray in outdoor settings. �;Mxffi v. All TimberForm and TimberForm-2 Posts undergo MaxTreat processing prior to pressure -preservative treatment. MaxTreat is an exclusive two-step fabrication procedure that dramatically increases the effectiveness of the treatment. The process includes two steps, incising and kerfing, When combined, these two processes greatly enhance preservative penetration and retention when timbers are pressure treated in an autoclave. See page 55 for more information. Wood Preservative All wood components used on TimberForm, TimberForm-2 & PipeLine Play Areas and Accessories are pressure-preservativeiy treated after all fabrication is completed with a child - friendly wood preservative. TimberForm does not and has never used arsenic -based wood preservatives. Conserving and Enhancing America's Forests TimberForm Playground equipment grade" timber is obtained by Columbia Cascade from Northwest America sources that adhere to strict and ecologically sound sustained yield practices. For every tree felled for playground equipment use, at least three genetically superior seedlings are planted for use by future generations of players. How to Use This Catalog Within the covers of this catalog, you'll find all -new selections of TimberForm, PipeLine and TimberForm-2 play areas. The more than 2,000 play accessories we offer are also illustrated within these pages. Columbia Cascade play systems are modular in design and most accessories are interchangeable, between different systems. This modularity provides the opportunity to create playground equipment that will fulfill the uncompromised needs of the users, the specifier and the owner. The play areas presented in this catalog are just the beginning. We encourage choosing features from several models and melding them into your own unique design. Our design team is ready to assist you.

Toothman-Orton Engineering Company 9777 Chinden Blvd. Boise, Idaho 83714-2008 (208) 323-2288 TABLE OF CONTENTS: INTRODUCTION POST DEVELOPMENT Figure 1 - Post -Development Drainage Areas Peak Flow Calculations (Qso, Qioo) Storage Volumes Calculations Using (Qioo) INTRODUCTION The Three Corners subdivision is located at the southeast corner of Chinden Blvd and Locust Grove Road. A parcel of land located in the North Half of the Northwest 1/4 of Section 29, Township 4 North, Range 1 East, Boise Meridian, Ada County, Idaho. The +38-acre site consists of commercial and residential development as well as a new local roadway (Three Corners Drive). This report covers the drainage associated with a portion of the new roadway (Three Corners Drive) as well as the drainage for 5 commercial lots in the northwest corner of the subdivision. The existing site slopes gradually down to the northwest. The existing grades are generally less that 1 %. There are existing irrigation and drain ditches that run along the perimeter of the property. The post -development area was separated into ten (10) drainage areas as shown on Figure 1 - Drainage Areas. The drainage is for the roadway and associated sidewalk and landscaping as well as 5 commercial buildings and associated parking, landscaping, and sidewalk. The storm water will be treated in underground seepage beds and an above ground drainage swale by a combination of retention and infiltration. Geotechnical data including groundwater elevation was obtained from reports provided by Strata, Inc. (Report #DEADAV B07178A). PEAK FLOW CALCULATIONS The Rational Method was implemented to calculate the peak storm water runoff flows (Qp) using a 100-year and 50-year return frequency and storm duration equal to the time of concentration (Q. The 50-year peak runoff flows were used for peak flows through the pipes and sand & grease traps. The 100-year storm was used to determine the required capacity of the seepage beds. The peak flow calculations are controlled by the impervious pavement areas. A minimum time of concentration of 10 minutes was used for peak flow calculations. See attached calculations. There will only be two areas of access to this portion of Three Corners Drive. Those areas are shown on Figure 1 - Drainage Areas. Therefore the contributing drainage areas include the Three Corners Drive roadway, a small portion of an access drive, a portion of Sweet Valley Way, '/z of the associated residential lots, and associated sidewalks and landscape areas. STORAGE VOLUME CALCULATIONS The volume of runoff (V,) was calculated to retain 100% of the drainage from the roadway including a portion of a commercial access drive, a portion of the future Sweet Valley Way, associated sidewalks, '/2 of associated residential lots, and landscape areas using 100-year return frequency and 1-hour storm duration. Excavation for the seepage beds is to be through the layers with clay and/or silt to the free draining poorly -graded gravel layer. An infiltration rate of 8 inches per hour was used per the geotechnical report. See attached calculations. In addition to the 3 seepage beds, three (3) sand & grease traps (one per seepage bed) will be used to limit sediment buildup. The sand & grease traps have been sized to keep the velocity through the throat below 0.5 fps.
