Last Updated: November 11, 2026 - **Permits:** City of Rockwall (permits confirmed per address) - **Storm drainage:** City of Rockwall (streets, right-of-way and drainage easements) - **The rule that changes the job:** Engineer's grading plan ## What usually starts a drainage job in Rockwall ### A newer house that drains worse each year Rockwall asks for an engineer's grading plan on new homes. When the yard stops draining, that plan shows the slope the lot was built to, and the fix brings it back. ### A pipe aimed at the fence Someone ran a drain line to the back fence. Rockwall's plat reviews allow no lot-to-lot drainage, so water leaves as sheet flow at the line or through an easement. ### Roof water at the slab Downspouts empty into beds against the foundation. Buried lines carry the water to the street side, where the lot was designed to shed it. ### A soggy corner by the lake side One corner of the yard holds water long after the rest has drained. A catch basin collects it and solid pipe carries it to an outlet the lot can use. ## Newer Rockwall yard that’s stopped draining? A new house usually drains well at first. A few years on, the back yard holds water, the beds by the slab stay wet, and nobody is sure what changed. [Clay Plano Drainage Company](https://clayplanodrainagecompany.com/) regrades yards and builds French drains, catch basins and downspout lines in Rockwall. On a newer house, we start with the plan the lot was built to, because Rockwall asks for one. ## The grading plan your lot was built to Rockwall asks for residential new construction to come with a grading plan prepared by a Texas professional engineer. That drawing shows how the lot was meant to shed water: the high points, the swales and where water leaves. For a drainage fix, it is the most useful document you can find. It tells us the slope the yard was designed to have, so we can measure how far it has drifted rather than guessing. Where to look for it: - **Your closing papers** or the builder’s handover package. - **The builder,** who may have kept the lot’s plan. - **The city’s records** for the address. If it can’t be found, we work from elevations taken on the visit. ### Older lots without a plan Houses built before the grading plan rule, or lots whose plan has been lost, still drained to some design. We find it on the ground: the high point of the lot, the swales along the sides, and the spot where water was meant to reach the street. Elevations from the slab to each of those points show where the fall has gone missing, and that becomes the plan we build back to. ## How a designed grade drifts A lot graded to plan doesn’t stay that way on its own. Over a few seasons, small changes add up until water no longer follows the design: - **Settling** where soil was filled during construction, leaving low spots near the slab or along utility trenches. - **Beds and borders** that raise the ground against the house. - **A fence, shed or patio** placed across the swale the plan relied on. - **Downspouts** that empty where the plan never expected so much water. The fix is usually to restore the designed slope with [yard regrading](https://clayplanodrainagecompany.com/yard-grading/), then move roof water with [downspout lines](https://clayplanodrainagecompany.com/downspout-drainage/) so it doesn’t undo the work. ## No lot-to-lot drainage, sheet flow at the line Rockwall’s plat reviews state the rule plainly: no lot-to-lot drainage. Water leaves a lot as sheet flow at the property line, or through an easement on the neighbor’s lot. Sheet flow is water spread thin across the ground, the way rain leaves a gently sloped lawn. A pipe or a deep swale aimed at the fence does the opposite, gathering water into one stream and dropping it on one spot of the next yard. For your drain, that means: - **No pipe ending at the back fence,** however short the run would be. - **Collected water goes to your street side,** through an emitter, a curb line or a basin. - **The ground at the line stays as designed,** so the neighbor sees the same thin flow the plan intended. The guide to [water from a neighbor’s yard](https://clayplanodrainagecompany.com/guide/neighbor-water-runoff-texas/) covers runoff between lots under Texas law. ## Roof water comes first The roof gathers rain from a wide area and drops it at a handful of downspouts. Where those downspouts empty into beds against the foundation, the slab edge takes the whole roof’s runoff. Moving that water is the cheapest step and the one that protects the rest of the work: - **Solid pipe from each downspout,** buried under the lawn, to an emitter or outlet on the street side. - **Cleanouts** where lines join or turn, so leaves can be flushed out later. - **Splash areas closed off,** so beds by the slab stop taking the full roof’s runoff. With roof water handled, a regrade or basin only has to carry what falls on the yard itself. ## Basins, French drains and wet corners Where water gathers in one corner, a [catch basin](https://clayplanodrainagecompany.com/catch-basins/) collects it and solid pipe carries it away. Where a long strip stays wet, a [French drain](https://clayplanodrainagecompany.com/french-drain-installation/) can collect water along its length. The [French drain vs catch basin guide](https://clayplanodrainagecompany.com/guide/french-drain-vs-catch-basin/) explains which suits which spot. We probe the soil on the first visit rather than assume it, since the ground’s speed at taking water decides how much stone and pipe the collector needs. A patch that stays wet in dry weather may be a leak, not runoff; the [soggy yard guide](https://clayplanodrainagecompany.com/guide/soggy-yard-no-rain/) shows how to tell. ## Around the lake and I-30 Rockwall sits on the east shore of Lake Ray Hubbard, with I-30 crossing it and SH 205, SH 66 and SH 276 running through. Its neighbors write their own rules: - **[Heath](https://clayplanodrainagecompany.com/service-areas/heath/)** treats lot-to-lot drainage between two or fewer lots as a private matter. - **[Rowlett](https://clayplanodrainagecompany.com/service-areas/rowlett/)** requires a grading permit when dirt is added, removed or moved on a lot. - **[Lavon](https://clayplanodrainagecompany.com/service-areas/lavon/)** charges for a right-of-way activity permit and sets a minimum size for driveway culverts. ## How we work a Rockwall yard We build back toward the design the lot was given, not around it. - **Plan first.** The lot’s grading plan, or our elevations where there isn’t one. - **Source before collector.** Roof water, sprinklers and the lot above each need a different fix. - **Outlet on your side,** never a pipe at the fence. - **Water run through** before backfill and across the new grade. - **Sod and sprinklers back,** and a walk around the finished yard with you. The [guide to fixing yard drainage problems](https://clayplanodrainagecompany.com/guide/how-to-fix-yard-drainage-problems/) sets out the same order, and [whole-yard drainage](https://clayplanodrainagecompany.com/yard-drainage/) covers lots with water arriving from several directions. ## Drainage services in Rockwall - [Service**Yard grading** Reshaping the soil so the ground falls away from the slab and toward a swale or the street, set to measured slopes instead of guesswork.](https://clayplanodrainagecompany.com/yard-grading/) - [Service**French drains** A trench of washed stone and pipe that collects water held in the soil and carries it to a legal outlet at the street side of the lot.](https://clayplanodrainagecompany.com/french-drain-installation/) - [Service**Catch basins** A grated box set at the lowest point of a lawn, bed edge or patio that takes in surface water and sends it through solid pipe to an outlet.](https://clayplanodrainagecompany.com/catch-basins/) - [Service**Downspout drainage** Buried solid pipe that takes roof water from each downspout past the beds and the slab to a pop-up emitter, an existing line or a permitted curb outlet.](https://clayplanodrainagecompany.com/downspout-drainage/) - [Service**Yard drainage systems** One planned route that collects roof, surface and soil water from several parts of the yard and carries it in solid pipe to a legal outlet.](https://clayplanodrainagecompany.com/yard-drainage/) ## How a job usually runs in Rockwall ### Find the grading plan Send the address, photos from the last storm and the lot's grading plan or survey if you have it. On a newer Rockwall house, that plan is the starting map. ### Compare the yard to it On the visit we take elevations, probe the soil and compare the yard with the designed grade. The written estimate shows where it has drifted and how we bring it back. ### Permits and locates What the city needs for your job is confirmed for the address and arranged as part of the work. Texas811 marks utilities and we paint the route in white. ### Build, test, put back We cut the sod in strips, shape or trench, run water across the new grade and through any pipe before backfill, then lay the sod back and walk the yard with you. ## Neighborhoods, landmarks and routes ### Landmarks - Lake Ray Hubbard ### Routes - I-30 - SH 205 (Goliad Street) - SH 66 - SH 276 ## Rockwall: questions ### Does my Rockwall house have an engineered grading plan? If it was built recently, probably. Rockwall asks for residential new construction to have a grading plan prepared by a Texas professional engineer. The builder, your closing papers or the city's records may have it, and it shows how the lot was meant to drain. ### Can I run my Rockwall yard drain to the back fence? Not as a pipe that empties onto the next lot. Rockwall's plat reviews allow no lot-to-lot drainage: water leaves as sheet flow at the property line, the way the lot was graded, or through an easement on the neighbor's lot. We plan outlets toward the street side. ### What is sheet flow at the property line? It's water moving across the ground in a thin, spread-out layer, the way rain runs off a gently sloped lawn. A pipe or swale that concentrates water into one stream at the fence is different, because it puts all of it on one spot of the neighbor's lot. ### What will a regrade or catch basin cost in Rockwall? We use one set of rates in every city. Our typical range for yard regrading is $1,000 to $4,000 per project, and a catch basin with a short pipe run is $500 to $1,500 per basin. Underground downspout lines are $300 to $800 each. The written estimate after the site visit sets yours. ### Do I need a Rockwall permit to regrade an existing yard? Rockwall's grading plan rule covers new homes. What applies to regrading or a drain on an existing lot is confirmed with the city for your address, and any permit the job needs is arranged as part of the work before it is scheduled. ## Nearby service areas - [City of Heath (residential re-grading permit)**Heath**](https://clayplanodrainagecompany.com/service-areas/heath/) - [City of Rowlett Development Engineering (grading and right-of-way permits)**Rowlett**](https://clayplanodrainagecompany.com/service-areas/rowlett/) - [City of Lavon (Right of Way Activity Permit)**Lavon**](https://clayplanodrainagecompany.com/service-areas/lavon/) ## Guides for yards in Rockwall - [Learn**How do you fix yard drainage problems?** Start with where the water comes from, not with a drain.
