issue, which is scheduled to go to City Council in April 2017. 8

9

PROPOSED OPTIONS 10 Staff has prepared the following three options for the Planning Commission to consider. Options 11

may be modified as desired by the Planning Commission. Public notice for the public hearing 12

RSR Impervious Surface Review April 5, 2017

of 6

ANALYSIS 1 Use of RSR in Tumwater and the Tumwater UGA 2

The Residential/Sensitive Resource (RSR) designation was created to address environmentally 3

sensitive areas and as a method to preserve open space. It was included in the 1995 4

Tumwater/Thurston County Joint Plan and Title 22 Tumwater Urban Growth Area Zoning in 5

1996. The intent is to accommodate low-density residential neighborhoods while still meeting 6

density goals of the Growth Management Act and provide services. The use of this designation 7

in the 1995 Joint Plan was limited to areas that included sensitive wetlands and areas in sensitive 8

watersheds (Percival Creek). 9

The Thurston County/Tumwater Joint Plan was amended in 2010 to account for surfacing high 10

groundwater flooding issues outlined in the Salmon Creek Basin Plan. The RSR designation was 11

specifically amended in the joint plan in 2010 to apply to environmentally hazardous areas. 12

Attachment A includes the current Joint Plan Land Use Maps for the unincorporated Tumwater 13

UGA as well as the current City of Tumwater Comprehensive Plan Land Use Map. Please note, 14

the joint plan land use map still includes two large areas that have been annexed by the City of 15

Tumwater. 16

Also in Attachment A, are maps of the areas zoned RSR 2-4 DU/AC in the unincorporated 17

Tumwater UGA, including: 18

Name Number of Parcels

Total Acreage Parcel Size Range

1 Sapp Road 8 51.31 1.18 to 9.82 2 Sapp Road 2 1 1 1 3 Sapp & Linwood 7 10.11 0.44 to 2.46 4 Linwood Avenue 6 8.99 0.24 to 2.38 5 Rural & Trosper 1 13.89 13.89 6 88th Avenue 70 147.07 0.06 to 18.31 Totals 93 232.37 0.06 to 18.31

19

The parcel sizes in the zoning district currently range from 0.06 up to 18.31. There are four 20

parcels greater than 10.0 acres, ten parcels between 5.01 and 10.0 acres, 28 parcels between 1.0 21

and 5.01 acres, with the remaining 51 parcels one acre or less. 22

Other Critical Areas in the Study Areas: 23

The RSR designation has also been used for properties with other critical areas such as 24

significant wetlands, riparian areas, and uplands of important streams such as Percival Creek. 25

This designation is used along with the County’s Critical Areas Ordinance to protect sensitive 26

areas. 27

High Groundwater Flooding and Critical Areas Regulations: 28

The 88th Avenue area is designated as RSR 2-4 in the southern Tumwater UGA and is subject to 29

periodic surfacing high groundwater flooding. Surfacing high groundwater flood regulations 30

will still limit development in areas prone to this type of flooding. Areas that are subject to high 31

Page 2 of 51


of 6

groundwater flooding were added as a special management area in the Thurston County Critical 1

Areas regulations in 2000 with Ordinance No. 12155. These regulations were updated and 2

amended with the 2012 Critical Areas Ordinance Update. The regulations were the result of the 3

serious groundwater flooding that occurred throughout Thurston County in 1998-1999. This 4

flooding led Thurston County to declare a local emergency in February of 1999 (Resolution No. 5

11890), which was replaced in May 1999 (Resolution No. 11931), and to adopt a moratorium 6

(Ordinance No. 12010) in August of 1999 suspending the issuance of certain permits, including 7

subdivision and building permits, until high groundwater regulations could be adopted. This 8

flooding also resulted in the Salmon Creek Basin Plan. 9

High groundwater flooding occurs when subsurface geologic conditions prevent water from 10

moving out of an area either to a deeper aquifer or laterally through the soil as fast as the water 11

enters the groundwater system. Aside from surface flooding, high groundwater can cause the 12

failure of on-site wastewater treatment systems, contamination of drinking water wells, and 13

interfere with surface stormwater facilities. 14

December 2016 Low Impact Development Amendments 15

The County adopted new low impact development regulations in the Tumwater UGA with 16

Ordinance No. 15390. Previous to this, there was no stated impervious surface standard for this 17

zoning district. Impervious surfaces were limited by the overall density limitations, building 18

coverage on each lot, and other limits. The new standards changed the lot coverage standards 19

from an overall building coverage limit to an impervious surface coverage limit. 20

22.08.050 - Density regulations. 21

Density regulations in the RSR zone district are as follows: 22

23

… 24

G. Lot Coverage, Maximum for All Buildingsimpervious surface: forty percent of total area of 25

the lot or seven thousand five hundred square feet, whichever is less; 26

… 27

In the past couple of months it has been found this standard does not adequately account for the 28

larger lots found in areas designated as RSR in the unincorporated Tumwater UGA. 29

City of Tumwater Recommendations 30

The City of Tumwater began working on the proposed amendment with their planning 31

Commission in February 2017, and is expected to complete their decision in April or May of this 32

year depending on City Council timelines. 33

34

The City of Tumwater Planning Commission held a public hearing on March 14, 2017. The 35

written public hearing comments are located in Attachment B. 36

37

The current City of Tumwater Planning Commission recommendation to their City Council is 38

included in Attachment C. If there are any changes from the City Council, staff will provide 39

these to the Planning Commission in advance of the public hearing. 40

G. Lot coverage, maximum for all buildingsimpervious surface: 8

1. The maximum impervious surface for lots smaller than one acre is forty percent of the 9

total area of the lot or seven thousand five hundred square feet, whichever is less;, 10

11

2. The maximum impervious surface for lots between one acre and less than five acres is 12

seven thousand five hundred square feet plus an additional two thousand square feet for 13

every additional acre in lot size, rounded to the nearest acre, 14

15

3. The maximum impervious surface for lots five acres and larger is fifteen thousand five 16

hundred square feet plus an additional three thousand square feet for every additional 17

acre in lot size, rounded down to the nearest acre, 18

From: Joel Pedersen <[email protected]>Sent: Wednesday, March 1, 2017 8:18 PMTo: Jeremy DavisSubject: Impervious surface limits

I would like you to immediately address the maximum impervious surface limits in the Residential Sensitive Resource District by adding this issue to your 2016‐2017 docket. The current 7500 sq ft maximum lot coverage is unnecessarily preventing larger parcel owners from utilizing their property. These limits left unchanged, will unfairly burden a high percentage of land owners in the Residential Sensitive Resource District.

Jeremy Davis

From: J Pedersen <[email protected]>Sent: Wednesday, March 1, 2017 8:34 PMTo: Jeremy DavisSubject: Add Impervious Surface Limit in RSR review to 2016-17 Docket

Dear Jeremy,

I would like to request the County add the item to amend Tumwater UGA Zoning Ordinance to Review Impervious Surface Coverage in the Residential Sensitive Resource Zoning District to their 2016-17 Docket. I have owned approximately 10 acres at 2519 Sapp Rd SW for almost 50 years. I have been using this property very modestly and preserving its natural condition for the benefit of the generations that will come after me. This property was part of the original land grant my husband's grandfather was issued in 1869. My family has continued to be good stewards of this land for 148 years. The time will come when I leave this 10 acres to my own two children. My hopes and dreams for this treasured land is that I can provide each of my kids with a building site.

The current limitation of 7500 sq ft of impervious surface has just taken that dream away. My property has so many other critical areas that reaching a building site outside of the seasonal streams, wet areas, and steep slopes would be impossible with only 7500 sq ft allowed. My property is about 1260 feet long and 325 ft wide. A steep slope runs right down the middle with a seasonal stream not too far from it. In order to avoid those areas and meet the existing setbacks, a long driveway would have to be built to reach the back of my property. You can see that reaching 1000 - 1200 feet back with a driveway would take over 10,000 sq ft of impervious surface. That makes it impossible all together. I don't think the people who wrote the limit of 7500 sq ft really looked to see what that limit would be doing to property owners. I hope you will add this to your Docket so you can increase the limits to an amount high enough to build a long driveway and a nice size house with outbuildings. This reasonable amount of building is what should be allowed for our freedom in the use of our own property.

This extreme limitation seems to be a regulation for the sake of a regulation. The critical areas are already tremendously protected by setbacks preventing most of our land from being used anyway. The limits already in place are satisfactorily protecting the environment and keeping it safe. Please help change this unfair limit, as we have taken great care of this property over the last 148 years and really don't need ridiculous rules to help us.

Thank you for looking into and pursuing this change.

Sincerely,

of 51

Jeremy DavisFrom: Kelly McNamara <[email protected]>Sent: Thursday, February 23, 2017 11:38 AMTo: Jeremy DavisSubject: Impervious Surface Coverage

Mr. Davis, I have been made aware of yet another issue regarding the Impervious Surface requirements in the Residential Sensitive Resource Zone District. As a real estate agent for many years in this area, I have had a number of clients and friends who have been affected by these well intentioned rules limited use on large parcels. While intended to protect resources, it seems it has had the un-intended effect of severely limiting the use of properties in an inequitable way with those having large parcels more adversely affected than others. All of the people I know that have been affected have not been trying to do major projects or disruptions, but rather trying to utilize the space in a minimal way. It seems that the current rules as written need to be revisited to perhaps better balance the impact on large and small parcels. It seems this would be an ideal item to add to the County’s Docket for 2016-17 and I would encourage you to do so. Thanks for your consideration.

From: J Pedersen <[email protected]>Sent: Tuesday, February 21, 2017 11:33 AMTo: Jeremy DavisSubject: request to add the RSR impervious sufrace coverage item to the 2016-17 docket

Dear Jeremy Davis, I would like to see the item regarding the “40% or 7500 sq ft, whichever is less” impervious surface limit in the RSR district reviewed and added to the Thurston County Docket for 2017. This should be done immediately as it is preventing larger parcel owners, like me, from reasonable use of their property. I have applied for a building permit, and this limit is currently preventing me from being issued a permit to build a necessary structure. This limit is so restrictive that many property owners in the RSR zone have lost any ability at all to build on their parcels. The land within this zone is inherently restricted from building due to environmentally sensitive areas on these properties. Parcels in the RSR zone have critical areas such as seasonal streams, wetlands, steep slopes, and gopher soils. Just finding a suitable building site can be a challenge considering those parameters. The 7500 sq ft maximum impervious surface limit currently in place does not even allow a driveway long enough to access environmentally suitable building sites on many parcels. Consider a driveway that needs to be 750 ft long in order to reach a buildable site. This, in itself, at 10 ft wide reaches the 7500 sq ft limit. There are at least five 9.82 parcels in my neighborhood where long driveways were/will be necessary, mine included. I have a 1000 ft long driveway and the parcel next to mine has critical areas in every section except for the back of it. This will require at least an 1100 ft long driveway (11,000 total sq ft) to access an environmentally acceptable building site. The 7500 sq ft limit doesn’t even allow enough for completing a driveway. Additionally, in my case, with a 9.82 acre parcel, imposing a 7500 sq ft limit on 427,759 sq ft of property is an unjustifiable limitation. This limitation results in only 1.75% use of my property. This is an inequitable limitation compared to the 40% coverage (which is a second measurement listed in this provision) allowed on neighboring lots within this RSR zone. This disproportionate limit is outside the original intent of the RSR zone. I was a member of the original committee to establish the RSR zone in 1995, and I recall this 7500 sq ft limit being written as a measurement for small lots within planned residential communities. Its application to larger lots is too limiting and unfair. Both of these situations illustrate how the current impervious surface limit of “40% or 7500 sq ft, whichever is less” is unsuitable for larger parcels and should be amended as soon as possible. It is an unfair and unnecessary limitation on larger parcel owners and is preventing people from reasonable use and enjoyment of their land. I believe this regulation is posing undue hardship unnecessary in carrying out the spirit of the RSR designation and request the County to add this item to their 2016- 2017 Docket. Thank you for your time and consideration in amending this, Jorjana Pedersen 2425 Sapp Rd SW Olympia, WA 98512

From: [email protected]: Wednesday, March 1, 2017 8:25 PMTo: Jeremy DavisSubject: Add RSR Impervious Surface Limit review to 2016-17 Docket

Dear Jeremy, I would like to request the County add the item to amend Tumwater UGA Zoning Ordinance to Review Impervious Surface Coverage in the Residential Sensitive Resource Zoning District to their 2016-17 Docket. I have owned approximately 10 acres at 2519 Sapp Rd SW for almost 50 years. I have been using this property very modestly and preserving its natural condition for the benefit of the generations that will come after me. This property was part of the original land grant my husband's grandfather was issued in 1869. My family has continued to be good stewards of this land for 148 years. The time will come when I leave this 10 acres to my own two children. My hopes and dreams for this treasured land is that I can provide each of my kids with a building site. The current limitation of 7500 sq ft of impervious surface has just taken that dream away. My property has so many other critical areas that reaching a building site outside of the seasonal streams, wet areas, and steep slopes would be impossible with only 7500 sq ft allowed. My property is about 1260 feet long and 325 ft wide. A steep slope runs right down the middle with a seasonal stream not too far from it. In order to avoid those areas and meet the existing setbacks, a long driveway would have to be built to reach the back of my property. You can see that reaching 1000 - 1200 feet back with a driveway would take over 10,000 sq ft of impervious surface. That makes it impossible all together. I don't think the people who wrote the limit of 7500 sq ft really looked to see what that limit would be doing to property owners. I hope you will add this to your Docket so you can increase the limits to an amount high enough to build a long driveway and a nice size house with outbuildings. This reasonable amount of building is what should be allowed for our freedom in the use of our own property. This extreme limitation seems to be a regulation for the sake of a regulation. The critical areas are already tremendously protected by setbacks preventing most of our land from being used anyway. The limits already in place are satisfactorily protecting the environment and keeping it safe. Please help change this unfair limit, as we have taken great care of this property over the last 148 years and really don't need ridiculous rules to help us. Thank you for looking into and pursuing this change. Sincerely, Rosemary L. Shattuck ____________________________________________________________ Affordable Wireless Plans Set up is easy.

Hi Jeremy, Our family owns approximately 10 acres in Tumwater at 2438 Sapp Road NW. The current proposal discriminates against large property owners. The proposal says that property owners would be allowed 7,500 sq ft of impervious surface or 40%, whichever is less. This means that a 1/2 half acre piece of land would be allowed nearly 40% of impervious surface and a 10 acre piece of land would only be allowed 2.5% of impervious surface. Also, these surface restrictions would very much impact our ability to put a long driveway to any potential building site. Additionally, the entire northern portion and much of the eastern portion of our land is Category II wetlands and regulated setbacks. That, alone, greatly reduces our hopes for future development of our land. Thank you for adding this impervious surface issue to the docket on March 14. Sincerely, Teresa Shattuck On behalf of Patrica Shattuck and Family.

of 51


"Lot coverage" means the amount or percentage of ground area covered or occupied by impervious surface(s)building(s) usually expressed in square feet or percentage of land on the lot and measured horizontally at the foundation.

Section 3. Tumwater Municipal Code Section 18.08.050 is hereby amended to read as follows: 18.08.050 Density regulations. Density regulations in the RSR zone district are as follows:

A. Site Area. All land divisions are subject to the lot size provisions of this section, provided that all land divisions must meet the following density requirements:

1. Minimum: two dwelling units per acre;

a. In situations where density requirements and lot size, shape, topography, or location result in a subdivision that cannot possibly meet the density requirements, a reduction in minimum density (i.e., an increase in maximum lot size) may be granted by the community development director if all of the following criteria can be met:

i. The lot to be subdivided must be less than or equal to one-half acre in total area.

ii. The reduction in minimum density may not result in more than one additional single-family dwelling.

iii. The reduction in density will not result in a density that is less than eighty-five percent of the minimum density required in the applicable zoning district.

iv. The conditions unique to the site (size, shape, topography, etc.) are not the result of actions by the applicant.

v. In no event may a reduction in density be granted if it would result in a use that would not be allowed as a permitted use, accessory use, or conditional use in the district in which the property is located.

2. Maximum: four dwelling units per acre, or if a land division is subject to the clustering provisions of subsection E of this section and not subject to the wetland protection standards of TMC Chapter 16.28, the maximum density shall be no greater than one hundred twenty-five percent of the maximum density that would otherwise be allowed.

B. Density Calculation. The calculation of the density requirements in subsection A of this section is based on the portion of the site that contains lots devoted to residential and associated uses (e.g., dwelling units; private community clubs;

of 51


stormwater detention, treatment and infiltration). The following land is excluded from density calculations:

1. Land that is required to be dedicated for public use as open space, right-of-way, or land on which development is prohibited by TMC Title 16, Environment, and land that is to be used for private roads. Provided, that portion of open space/park areas that consists of stormwater facilities and that is designed for active and/or passive recreational purposes in accordance with the drainage design and erosion control manual for Tumwater shall not be excluded from density calculations;

2. Land that is intended for future phases of development created in accordance with TMC 18.08.060;

3. Land that consists of lots devoted to uses other than residential and associated uses, including but not limited to churches, schools, and support facilities (except for stormwater detention, treatment and infiltration facilities).

C. Division of Land Not on Public Sanitary Sewer. Division of land in areas without sewer must occur in a manner that maintains long-term potential to achieve minimum required densities and efficient provision of sewer once sewer becomes available. For a proposed division of land not required to be served by the extension of public sewer or a community septic system at the time of approval, a conversion plan shall be submitted in accordance with TMC 18.08.060 for the entire property, and the proposed land division shall be subject to the following:

1. For land division of an existing lot of record created prior to September 15, 1998:

a. Any division creating two lots shall not be subject to the minimum density requirements of subsection A of this section, provided one of the lots created is at least five acres in size. A note must be included on the recorded land division that future land divisions shall meet minimum density requirements of subsection A of this section in each phase of development.

b. Any division creating more than two lots shall meet the minimum density requirements of subsection A of this section in each phase of development.

D. Lot Size Requirements.

1. Maximum: no maximum lot size;

of 51


3. In the event that the minimum lot size provisions above make it impossible to achieve the minimum density permitted under subsection A of this section, one or more lots may be reduced in size by up to ten percent. This provision may be applied only to the minimum number of lots necessary to allow the minimum density to be achieved.

E. Clustered Subdivision. Any site in this zone district may be subdivided as a clustered subdivision, subject to the following:

1. The portion of the site dedicated for open space use shall be at least thirty percent of the area of the entire site;

2. At least one-half of the area dedicated for open space shall be useful for passive recreational purposes;
