Re: Today's Dental -City of Yelm Project Number - SPR-07-0135-YL
Review No.3 Site Construction Documents
Mr. Goroch:
The City of Yelm has completed the third review of Today's Dental construction documents.
Your application included:
• Construction Plans
• Landscape Plans
• Step Tank Calculations
We have reviewed the plans for compliance with the City of Yelm Development Guidelines, the
DOE Stormwater Manual and general standards of civil engineering practice. The following
comments need to be addressed before the plans may be approved for construction. Our
comments are summarized below:
Storm:
1. I did not see any indication of what storm water management manual was used for this
project. I assume that the 2005 D.O.E. Storm Water Management Manual was used for
this project, since the storm water treatment devices used are considered UIC's in which
would trigger the 2005 D.O.E. manual to be used for storm water design. Please clarify.
Step Sewer:
2. The step tank will have to be traffic rated, with no parking over tank per sewer dept.
previous request.
3. Submittals are usually submitted with step tank calcs at time of civil plan submittal for
review and approval. Note 6 on Sheet Notes for sheet C 14.01 sheet 7 of 22 calls out
the wrong detail callout (C 04.12 Detail "A").

4. Sheet # 11.01 "Phase 1 & 2 demolition plan" Note #17 denotes existing STEP to
be decommissioned. Sheet # 31.01 Phase 3 Demolition Plan Note #7 denotes
Protecting existing Septic Tank and Sanitary Pipe. What actually is going to
happen and when? It appears that the new tank is going to be installed, the
neighboring business hooked up to the new tank and the old tank
decommissioned and abandoned. Is this assumption correct? Existing STEP
tank must remain fully functional until such time as the new STEP tank is fully
functional and ready to receive wastewater.
The existing STEP Tank at Today's Dental is NOT H-20 load bearing rated and
must be protected from being driven over or parked on, prior to being
decommissioned.
6. Sheet c14.01 Utility Note #6 calls out for sewer lines to be SDR35 unless
otherwise specified Side Sewer labels call out schedule. 40 pvc. Side Sewers
need to be SDR35 and Pump service lines need to be Schedule 40 PVC.
7. Submittals must be received and approved by the City of Yelm Sewer Dept. for
the new tank.
8. Depth of bury for the new tank must be 5 feet or less from the invert elevation of
the inlet to the rim elevation of the highest rim.
Sheet C14.01 Sheet note 11 discusses connecting proposed sewer line to
existing Grease interceptor outlet Iine...The neighboring business also has a side
sewer not served by the grease trap. All lines feeding to the existing STEP tank
must be served by the new step tank.
10. Existing 2" sewer pressure line is a pressure main. It is to be left intact along with
the end of line clean-out in the proximity of the existing STEP tank.
11. Sheet C14.01 sheet note 12 calls for providing a 2" check valve assembly on the
existing sewer pressure line. This is not needed nor desired please leave
existing sewer pressure main alone with the exception of tapping for the service
line for the new tank.
12. Sheet C14.01 sheet note #6 The Sewer Department does not understand the
requirement that the service line run uphill to the main. We have not seen that
requirement before.
13. Please move pump control panel to closer proximity to the tank, near the Hose
Bib would be ideal.
Landscape and Irrigation:
14. Civil plans show 21 parking stalls proposed. A minimum of 22 are required per the land
use approval.
October 14, 2008 Page 2 of 3
15. Please provide a detailed corner enhancement plan as part of the landscape plans.
16. Please provide a detail of the proposed refuse enclosure. Refuse enclosures located
between or adjacent to buildings and a public way shall include an 8 foot masonry wall
consistent with the building. Materials and a 5 foot landscape buffer to screen the wall.
The located and access shall be approved in writing by Lemay prior to civil plan
approval.
17. Type I landscaping along the northwest property line shall include a 6 foot wood fence in
addition to the plantings.
18. A right of way dedication and waiver of protest are required for the deferral of frontage
improvements for Yelm Avenue, Solberg and Jefferson. They are required to be
submitted prior to civil plan approval.
Please review and revise the plans to address the above referenced comments. When the
project is resubmitted you will need to submit 4 sets of plans, 2 stormwater reports. The project
engineer should include a written response with the resubmittal, indicating how all the review
comments above have been addressed or responded to. This will significantly expedite our
review of the project. If you have any additional questions or comments please do not hesitate
to call or contact me at steveh@ci.yelm.wa.us.

Agent: Christine Phillips, BCRA
2106 Pacific Ave. Suite 300
Tacoma, WA 98402
Request: Proposed construction of a new 4,530 square foot office building
and Demolition of 2 existing buildings.
Action: Approval of the Site Plan Review with conditions
Findings of Fact
Site Plan Review
The Proposal includes phased demolition of 2 existing buildings and the construction of
1 office building with associated parking on approximately 0.58 acres.
A Notice of Application was mailed to local and state agencies and surrounding property
owners on March 29, 2007.
Section 17.84.020 (C) Yelm Municipal Code allows the Site Plan Review Committee to
approve a proposal when the site plan conforms to the standards, provisions and
policies of the city as expressed in its various adopted plans and ordinances including
the applicable sections of the shoreline master program for the Thurston Region.
Property Characteristics
The property is located at 502 Yelm Avenue West, and is identified by assessor tax
parcel numbers 21724142200 & 21724142300.
The current fee to connect to the City sewer system is $5,725.00 per Equivalent
Residential Unit (each ERU equals 900 cubic feet of water consumption per month, fee
subject to change).
Stormwater
Impervious surfaces create stormwater runoff which, when uncontrolled and untreated
can create health, safety, and environmental hazards. The City of Yelm has adopted
the 1992 Department of Eco/ogy Stormwater Manua/, which requires all development to
treat and control stormwater on site.
The applicant has submitted a preliminary stormwater plan which includes a conceptual
design for the treatment and infiltration of the stormwater. The preliminary site plan
shows stormwater facilities located off site. Stormwater must be treated and disposed
of on-site and be located outside of city right-of-way. In addition, the applicant has
proposed storm filters which are not an approved method within the City of Yelm. A
final stormwater plan is required as part of civil plan application submission.
Stormwater facilities require continued maintenance to ensure they remain in proper
working condition.
Parking
The City of Yelm Development Guidelines, Design Guidelines, and Municipal Code
address parking regulations from many aspects, including, but not limited to the design
of lots, the number of stalls required, pedestrian pathways within lots, and safety.
The requirements of off-street parking and loading facilities and their design shall be
regarded as the minimum; however, the owner, developer or operator of the premises
for which the parking facilities are intended shall be responsible for providing adequate
amounts and arrangement of space for the particular premises even though such space
or its arrangement is in excess of the minimum set forth.
As stated in Chapter 17.72 YMC, Dental Clinics require one and one-half parking
spaces per patient treatment room/area, plus one space per employee based on the
greatest number of employees on a single shift. In all parking facilities containing 25 or
more parking spaces, twenty-five percent (25%) of the required spaces may be
designated compact car. The total number of parking stalls required based on 4,530
square feet of Dental Clinic space consisting of 8 operatories and a maximum of 10
employees on a single shift is twenty-two (22) stalls. Additional parking is dependent on
the development of the adjacent piece of property to the west of the proposed
development.

Subject: Today's Dental Review Comments
Jon,
Thank you for taking the time to help address our questions regarding the third review of the Today's Dental Project. As
a follow up to our conversation this morning, I would like to summarize our discussion regarding the items listed in the
review letter from Mr. Harrington dated October 14, 2008.
• Item #2 of review letter: It was discussed and agreed upon that the Xerxes step tank we have proposed for the
project is H-20 load bearing rated and therefore it is acceptable to place the tank under the drive surface within
the proposed parking lot. No further action is required.
• Item #3 and #7 of review letter: It was discussed that shop drawings specific to the site tank design are
required to be submitted to the City of Yelm prior to ordering and installing the STEP tank in order to ensure
that the City's design standards are met and so that money and time are not wasted by the developer. It was
agreed that since a contractor is not yet on board for the project, shop drawings will not need to be submitted in
order to obtain the site permit and instead will only be required prior to ordering and installing the tank. Since a
note to this effect is currently on the plans, no further action is required.
Item #4 of review letter: It was discussed that it is acceptable to show the existing STEP tank as remaining in
place until the new tank is installed. Once the new tank is installed, fully functional and the waste line
connections are made, the existing tank will be filled with pea gravel and decommissioned per the Thurston
County Health Department requirements. The note currently shown on the plans will be revised to better clarify
the phasing of the STEP tank work.
• Item #8 of review letter: A distance of 53.5" was measured from the existing grade to the invert of the line
entering the STEP tank by a sewer maintenance employee with the City of Yelm. Given this information and
the fact that we will be cutting the site grades at the proposed STEP tank location by approximately 0.5-1', it is
anticipated that a maximum depth of bury of 5' can be achieved. The depth of bury for the proposed tank will
be reflected on the plans.
Item #13 of review letter: It was discussed and agreed upon that the proposed STEP tank pump control panel
will remain at its current location just southwest of the proposed building. It will be set on a Unistrut post. The
control panel and the hose bib will be within 50' and line of sight of the proposed STEP tank. It was agreed that
the control panel and hose bib need not be within close proximity to each other. No further action is required.
Please let me know if I have misunderstood anything discussed in our conversation this morning. We would be happy to
provide you with whatever information is needed to address your questions or concerns.
Thank you,
11/3/2008
