Antonoff P.E. SECTION 1- PROPOSED PROJECT DESCRIPTION _ - :, McCammant Homes wishes to build two four-plexes on an existing lot of record in the northwesterly portion of the City of Yelm. Approximately 0.29 acre of impervious area will be constructed on the 1 27 acre parcel The new impervious areas will drain into catch basins, which will convey the storm water to an appropriately sized infiltration system. SECTION 2- EXISTING CONDITIONS The subject property is located along the west side of Crystal Springs Rd. ,north of the Yelm Hwy_, neaz the intersection of Mr. Aire Ln. NW., within the city limits of Yelm, Washington. Yelm Creek flows along the extreme westerly margin of the property. The natural topography is slightly sloping downward from east to west, toward Yelm Creek. The native vegetation is primarily pasture grasses, with scattered native underbrush and deciduous tress. There is an existing single family residence onsite along with associated scattered sheds and out-buildings. Access to the existing property is via an existing gravel driveway off of Crystal Springs Rd. A compacted gravel drive circulates through the property to provide access. There is no established existing storm drainage on the property. The site storm drainage currently runs due west and infiltrates into the native soil SECTION 3- INFILTRATION RATES/ SOILS REPORT Test holes were dug in the summer of 2006 in the easterly portion of the property to determine the potential infiltration characteristics of the native soil. A coazse sand and gravel was encountered to a minimum of 72". No watertable or evidence of a winter watertable was observed. See soil log locations and descriptions on the storm drainage plan. SECTION 4- WELLS There is an existing individual well onsite which serves the existing residence. The well will be properly abandoned per Health Dept criteria- Water will be provided to the new structures via an City of Yelm existing watermaia New water services wiil be constructed onsite to provide domestic water service to the new structures- It is not anticipated that the proposed storm drainage facility will have any adverse impact on any wells in the immediate area. SECTION 5- FUEL TANKS Does not apply- No fuel tanks are known to be onsite_ SECTION 6- SUB-BASIN DESCRIPTION -~i P-~ ~ _r _.. .._ , The new impervious areas will drain into the proposed storm drainage system, which will be entirely from onsite runoff. No significant offsite area will be tributary to the ougite drainage system and the surrounding areas are relatively level, undeveloped andCahave excellent, well draining onsite soil The current area which will be paved is a crushed grave] and pasture grass surface. The area which will be collected by the proposed storm drainage system is essentially the area located at the east end of the property. The balance of the property will remain undisturbed. SECTION 7- ANALYSIS OF 100 YEAR FLOOD The proposed parking) access drive are significantly higher than the 100 year flood plain of an existing creek which flows along the westerly margin of the subject property, approximately 200 feet west. There is no history of flooding occurring on the existing developed portion of the property. No construction is proposed near or around the creek which traverses the extreme westerly margin of the property. The known 100 year flood plain has been indicated on the civil site plans, along with a recommended minimum finish floor elevation for the proposed structures- SECTION 8- AESTHETIC CONSIDERATIONS OF THE FACILITIES Landscaping per the city code will be implemented in and around the new parking and access drives. The entire storm drainage system will be underground so no aesthetic issues apply. SECTION 9- DOWNSTREAM ANALYSIS Does not apply. The increased runoff generated by this project will be mitigated by implementing an appropriately sized gravel filled infiltration system_ The system will be sized to handle a t 00 year and 7 day storm_ Consequently, unless the system malfunctions or a major storm occurs, no runoff from the site should occur. SECTION 10- COVENANTS, DEDICATIONS, EASEMENTS Does not apply_ The site is owned by the company. The storm drainage system will be privately owned and operated by McCammant Homes. SECTION 11-HOMEOWNERS- ARTICLES OF INCORPORATION Does not apply. Site is a commercial operation. EROSION ('ONTROL REPORT SECTION 1-CONSTRUCTION SEQUENCE AND PROCEDURE 1) Contact City of Yelm Public Works Department to arrange for apre-construction meeting. 2) Place silt fences as necessary and as directed by the City of Yelm inspector. 3)Install storm drainage system. Do not connect system to infiltration trench to storm system until site is paved and the potential for sedimentation has passed. 4) Fine grade site to slope sub-grade into catch basins. Install interim catch basin protection. 5) Maintain and regularly clean facilities during coarse of constnuction. Dismantle facilities only when site has stabilized and potential for sedimentation has passed. SECTION 2- TRAPPING SEDIMENT Does not apply. Site is essentially to grade, only a minor amount of fine grading will occur to direct the sub-grade into the proposed catch basins. Upon completion of the storm system installation and the minor grading it is anticipated the site will stand unpaved for a very short period of time. SECTION 3- PERMANENT EROSLON CONTROL AND SITE RESTORATION --Baer-aet-apply. Upon completion of the paving the majority of all exposed or disturbed surfaces will be covered SECTION 4- GEOTECHNICAL ANALYSIS AND REPORT Does not apply. A geotechnical study was not required by the city and is beyond the scope of a project this size. SECTION 5-INSPECTION SEQUENCE Inspection No- 1 -Installation of erosion control facilities prior to any cleazing or site prep. Inspection No. 2 -Completion of clearing and grubbing of site. Inspection No. 3 -Upon completion of installation of storm system and completion of minor grading. Infiltration trench inspected prior to backfill. Inspection No. 4 - Prior to paving, crushed gravel in place. Inspection No. 6 -Completion of project. MAINTENANCE PLAN FOR McCAMMANT HOMES FOUR PI,EXES CRYSTAL SPRINGS ROAD STORM DRAINAGE REPORT PARCEL 33020000100 903 CRYSTAL SPRINGS RD. PREPARED BY: MICHAEL N. ANTONOFF P.E. 3316 DEER IS. DR.

EAST BONNEY LAKE, WASH. 98391 (253)732-9453 OPERATION AND MAINTENANCE PLAN This operation and maintenance plan shall follow the included appendix "A"_ These checklists area for the general guidance for the maintenance and should be adopted as required by the conditions that may occur during normal operation of the site- The responsible maintenance organization is the current property owner, Brian McCammant , 20407 Cascade Dr_ East, Bonney Lake, Wash_ 98391, 253) 732-9453. Because of the sensitive nature of storm infiltration systems, and it's "out of sight, out of mind"placement, it is imperative that extreme care is implemented on what drains into the storm drainage system. As well it is imperative that proper protection and maintenance of the infiltration system is carried out. The checklist for the infiltration system is a guideline only. It is up to the owners of [he private system to insure the system is maintained, so that reduced performance us not reduced or eliminated due to siltation of the system's gravel structure. It is recommended that during the first year of operation, the free~Qrrey of inspection be monthly for all drainage system components. APPENDIX A MAINTENANCE SCHEDULE INSTRUCTIONS FOR USE OF MAINTENANCE CHECKLISTS The following pages contain maintenance needs for most of the components that are part of your drainage system, as well as for some components that you may not have. Let the C+ *Y know if there are any components that are missing from these pages. Ignore the requirements that do not apply to your system. You should plan to complete a checklist for all system components on the following schedule: (M) Monthly from November through April. (A) Once in late summer (preferable September) (S) After any major storm (use 1-inch in 24 hours as a guideline). Use photocopies of these pages and check off the problems you looked for each time you did an inspection. Add comments on problems found and actions taken. Keep these "checked" sheets in your fles, as they will be used to write your annual repor! Some items do not need to be looked at every tir: ,e an inspection is done. Use the suggested frequency at the left of each item as a guideline for your inspection. The facility-specific maintenance standards contained in this section are intended to be conditions for determining if maintenance actions are required as identified through inspection. They are not intended to be measures of the facility's required condition at all times between inspections. In other words, exceeding these conditions at any time between inspections and/or maintenance does not automatically constitute a violation of these standards. However, based upon inspection observations, the inspection and maintenance schedules shall be adjusted to minimize the length of time that a facility is in a condition that requires a maintenance action.
