Stormwater Design Manual
Christenson, Water Resources Utility Engineer, provided an update on
the final draft of the Lacey Stormwater Design Manual that will replace
the City’s current 1994 Drainage and Erosion Control Manual.
the NPDES Phase II Municipal Stormwater Permit, Lacey is required to
adopt and implement specific drainage requirements to control the
quality and quantity of stormwater runoff at nearly all new
development, redevelopment, and construction sites. The City’s new
drainage requirements must be at least as protective of water quality
as the criteria in the Department of Ecology’s (DOE) 2005 Stormwater
Management Manual for Western Washington, to meet the Phase II Permit
Doug stated in order to comply with the Phase II
Permit, Lacey’s new stormwater manual with its regulations and design
criteria must be adopted by ordinance and implemented before the
deadline, which DOE changed from August 16, 2009, to February 16,
2010. In early June 2009, the public review draft of the new manual
was posted on the City website, and the 470-page printed manual was
placed in City Hall and at the Lacey Timberland Library. An Open House
was held on June 19, 2009, to provide the public an opportunity to
comment on the new drainage manual. A Public Hearing for the new
manual was held on July 7, 2009; there were no public attendees or
comments received at the Hearing.
Doug explained that the new
manual has been condensed and rearranged from Ecology’s five-volume
manual, to ten chapters. A substantial amount of background and
supporting information was excluded since it’s not needed for local
drainage design. These changes to the manual make it concise,
straightforward, and easy to use for both the development community and
City staff. Some of the more significant changes incorporated since
the 2009 draft review is as follows:
- More emphasis
on low-impact development, by emphasizing techniques including design
criteria for rain gardens, permeable pavement, and other LID techniques.
- Additional information on site analysis and planning, site design, and selection of Best Management Practices (BMPs)
- Added more detailed information on BMPs and clarified their design criteria
more flexibility in some requirements, such as setbacks for
infiltration facilities can be adjusted based on site-specific
conditions and analysis
- More clarity provided for submittal requirements on drainage reports
the amount of infiltration and groundwater recharge after development
of a site to be at least equal to the natural pre-development
- It is more closely aligned with Thurston County’s new manual.
stated in order to comply with the Phase II Permit, Lacey’s new
Stormwater Design Manual with its regulations and design criteria must
be adopted by ordinance and implemented before the February 16, 2010,
deadline. The Planning Commission will hold a Public Hearing on
January 5, and any comments received by the public, City staff, or the
Planning Commission will be addressed.
Ryder asked if the Department of Ecology must approve our manual. Doug
explained that it is not a requirement.

Amended Interlocal Agreement for Water Rights Acquisition
Rector, Water Quality Analyst, presented the Committee with an amended
Interlocal Agreement for Water Rights Acquisition. The cities of
Lacey, Olympia, and Yelm entered into two previous interlocal
agreements for contracting consultants to acquire water rights to use
for water rights mitigation. The cities share equally the costs for
any acquired water rights. Phase I was for evaluating any water rights
in the Deschutes basin that may be used for mitigation purposes. Phase
II was for contacting water right holders, entering into option
agreements with willing sellers, and documenting water use history for
transferring water rights for mitigation. She explained that Phase II
has been a slow process primarily due to the limited number of willing
sellers, and the level of use documentation requested by the Department
of Ecology. As a result, the budget dedicated to Phase II has been
expended before Ecology’s information needs on one optioned water right
have been met.
Julie stated that the cities will need
additional mitigation besides any acquired water rights. Out-of-kind
mitigation, such as habitat restoration, has been proposed for
providing mitigation during winter months when instream flows may not
be met; however, the current interlocal agreement does not authorize
the cities to jointly purchase property or to fund habitat restoration
projects, nor does it authorize the cities to retain water rights
counsel as needed. She noted that the amended Interlocal Agreement
expands the activities that can be jointly funded by the cities to
include property acquisitions, developing restoration plans, and hiring
legal counsel if needed. The amendment will provide a budget for these
activities. The original $80,000 budget will be increased to
$230,000. The City of Lacey’s share will be $50,000, which is included
in the City’s 2010 budget.
Julie noted that one property owner
has expressed an interest in working with the cities to sell part of
his 200 acre farm. The cities have toured the property and the next
step will be to prepare a letter of intent.
NELSON MOVED TO RECOMMEND TO FULL COUNCIL TO AUTHORIZE THE CITY MANAGER
TO SIGN THE AMENDED INTERLOCAL AGREEMENT FOR WATER RIGHTS ACQUISITION,
AT THE JANUARY 14, 2010, COUNCIL MEETING. COUNCILMEMBER CLARKSON
